Note that FIG. 8B is a diagram of the information processing apparatus 100 viewed from the opposite side of FIG. 8A. FIG. 8B may be referred to as a bottom view. In addition, FIG.
It is sectional drawing corresponding to the dashed-dotted line X1-X2 of (B). In the information processing device 100 shown in FIG. 8, the touch sensor 600 is provided on the surface of the touch panel 500TP shown in FIG. Therefore, the sign portion 104b is provided on the surface opposite to the surface on the touch sensor 600 side. As shown in FIG. 8, by providing the sign portion 104b on the surface opposite to the surface on the touch sensor 600 side, the area 101 can be widened. In addition, the indicator 104b is provided on the touch panel 5
It may be provided inside 00TP. For example, it may be provided on the surface where the display unit 500 and the touch sensor 600 are attached, or inside the display unit 500 or the touch sensor 600. In addition, the marking portion 104b may be provided on the side surface of the touch panel 500TP. Touch panel 500TP
9A is a perspective view and FIG. 9B is a top view of the information processing apparatus 100 in which the marking portion 104b is provided on the side surface of the. As shown in FIG. 9, the area 101 can be widened by providing the marker portion 104b on the side surface of the touch panel 500TP.

Various shapes can be used as the marker Pt. The shape of the marker Pt may be any shape as long as it can be detected by the detection element 104a. Further, it is preferable that the markers Pt have different shapes. For example, one-dimensional code such as barcode, QR code (registered trademark)
You can use a two-dimensional code such as. Also, numbers, characters, symbols, figures, colors, etc. can be used as the marker Pt.

A plurality of markers Pt having different shapes are provided on the touch panel 500TP as a marker 104b.
Provided in various positions. When the touch panel 500TP is wound up by the winding unit 106, the relative positional relationship between the detection element 104a and the touch panel 500TP changes, so the marker Pt detected by the detection element 104a also changes. Therefore, the state of the touch panel 500TP, specifically, the touch panel 5 is determined based on the type of the marker Pt detected by the detection element 104a.
It is possible to obtain information on the area wound by the winding unit 106 of 00TP.

For example, when the marker Pt_h1 and the marker Pt_h2 are arranged in the marker 104b as illustrated in FIG. 4A, when the detection element 104a detects the marker Pt_h1, the information processing apparatus 100 displays the information illustrated in FIG.
When the detection element 104a detects the marker Pt_h2 in the state as shown in (B), it can be seen that the information processing apparatus 100 is in the state as shown in FIG.

In addition, for example, the drive unit 103 or the calculation unit 110 holds data indicating which type of the marker Pt is located at which position on the touch panel 500TP, and thus the detection element 10 is provided.
The area wound around the winding unit 106 of the touch panel 500TP can be calculated from the type of the marker Pt detected by the 4a.

Further, when the touch panel 500TP is wound around the winding unit 106, the detection element 104a
When the first information related to the state of the touch panel 500TP is obtained from the number of the markers Pt detected by, the shapes of the plurality of markers Pt may be the same. For example, when h markers Pt provided on the marker 104b are sequentially detected, a state in which h1 markers Pt are detected is different from a state in which h2 markers Pt are detected. Therefore, the number of detected markers Pt becomes the first information related to the state of the touch panel 500TP. In this case, the detection element 104a preferably has a function of determining whether the touch panel 500TP is wound up by the winding section 106 or, conversely, being unfolded from the winding section 106. For example, when a camera is used as the detection element 104a, it is possible to determine whether the touch panel 500TP is wound on the winding unit 106 or unrolled from the winding unit 106, depending on the direction in which the marker Pt moves in the image. I can.

<Structure example 2 of detection unit>
The detection unit 104 of this configuration example has a mechanism that detects the degree of rotation of the winding unit 106 with respect to the housing 105. The degree of rotation of the winding unit 106 with respect to the housing 105 is the total number of rotations or rotation angles of the winding unit 106 relative to the housing, or the total. For example, the degree of rotation of the winding unit 106 with respect to the housing 105 is determined by the touch panel 5
On the basis of the state in which 00TP is not wound by the winding unit 106, the winding unit 106
Refers to the total number of rotations or rotation angles. Therefore, when rotation is stopped once and rotation is performed again, the sum of all rotations is taken as the degree of rotation. In totaling, when the rotation in the winding direction of the touch panel 500TP on the winding unit 106 is positive, the rotation in the expanding direction is negative. The plus and minus may be exchanged.

As the detection unit 104, any unit may be used as long as it can detect the degree of rotation of the winding unit 106 with respect to the housing 105. For example, a potentiometer capable of detecting rotation can be used. At that time, it is preferable to use a potentiometer capable of detecting a plurality of rotations.

In this configuration example, the information about the degree of rotation of the winding unit 106 with respect to the housing 105, which is obtained by the detection unit 104, is supplied to the drive unit 103 or the calculation unit 110.

Further, the drive unit 103 drives the touch sensor 600 based on the first information supplied from the detection unit 104. Alternatively, the first information supplied from the detection unit 104 and the winding unit 10
6 based on the information such as the diameter of the touch panel 6 and the thickness of the touch panel 500TP.
The region wound by the winding unit 106 of 0TP is calculated, and the touch sensor 600 provided in the region not wound by the winding unit 106 of the touch panel 500TP is driven. Alternatively, the detection unit 104 supplies the first information to the calculation unit 110, and the calculation unit 110 calculates the touch panel winding from the first information and the information such as the diameter of the winding unit 106 and the thickness of the touch panel 500TP. The area wound around the take-up unit 106 is calculated. The second information calculated by the calculation unit 110 is supplied to the drive unit 103, and the drive unit 103 is provided on the touch panel 500TP in a region that is not wound by the winding unit 106 based on the second information. The sensor 600 is driven.

In the present specification, the first information or the second information related to the state of touch panel 500TP refers to all information related to the state of touch panel 500TP. The first information or the second information may be capable of knowing the state of the touch panel 500TP by combining with other information. Touch panel 5 by combining with other information
The information with which the state of 00TP can be known is, for example, the type of the marker Pt detected by the detection element 104a shown in the configuration example 1 of the detection unit. The type of the marker Pt detected by the detection element 104a is checked against the state of the touch panel 500TP, specifically, the state of the touch panel 500TP by comparing with the data indicating which kind of the marker Pt is located at which position of the marker section provided on the touch panel 500TP. It is possible to calculate the area wound by the winding unit 106 of the touch panel 500TP.

Further, the first information or the second information related to the state of the touch panel 500TP may be directly related to the driving of the touch sensor 600 driven based on the state of the touch panel 500TP. For example, information such as which control line is supplied with a control signal and which control line is not supplied with a control signal, which will be described later in the third embodiment, or which signal line's detection signal is used to determine which signal line Information such as whether to use the detection signal may be used. When the first information or the second information is sent from the detection unit 104 to the driving unit 103, the touch sensor 600 is limitedly driven without calculating the state of the touch panel 500TP in combination with other information. Can be done.

<< Operation of information processing device >>
The operation of the information processing apparatus 100 when the touch panel 500TP is partially wound up by the winding unit 106 will be described below.

(First step)
The winding unit 106 is rotated with respect to the housing 105 by the rotation mechanism provided in the housing 105, and the touch panel 500TP is partially wound around the winding unit 106 (see FIG. 4B). Here, the region 500TP_2 shown in FIGS. 4B and 4C is not wound by the winding unit 106.

(Second step)
The detection unit 104 determines the state of the touch panel. Thereby, the detection unit 104 obtains the first information related to the state of the touch panel. Specifically, the detection unit 104 uses the touch panel 500TP.
The first information relating to the region wound by the winding unit 106 is obtained. The above information is the detection unit 1
It depends on the configuration of 04. For example, in the configuration example 1 of the detection unit described above, as illustrated in FIG. 4B, the detection element 104a detects the marker Pt_h1. The information on the marker Pt_h1 is the first information on the state of the touch panel 500TP, specifically, the touch panel 500T.
This is the first information related to the region wound by the P winding unit 106.

(Third step)
The detection unit 104 supplies the first information on the state of the touch panel 500TP obtained in the second step to the drive unit 103. Specifically, the detection unit 104 supplies the first information related to the wound region to the winding unit 106 of the touch panel 500TP.

Alternatively, the detection unit 104 may supply the first information regarding the state of the touch panel to the calculation unit 110. The calculation unit 110 calculates second information related to the state of the touch panel based on the first information, and then supplies the second information to the driving unit. Specifically, the detection unit 104 calculates the first information related to the region wound by the winding unit 106 of the touch panel 500TP from the calculation unit 110.
Supply to. The calculation unit 110 calculates the second information related to the region wound by the winding unit 106 of the touch panel 500TP based on the first information, and then supplies the second information to the driving unit.

(Fourth step)
The drive unit 103 uses the touch sensor 60 based on the first information or the second information.
Drive part of 0. Specifically, the drive unit 103 drives the touch sensor 600 provided in a region of the touch panel 500TP that is not wound by the winding unit 106. Also,
The drive unit 103 does not drive the touch sensor 600 provided in the region wound by the winding unit 106 of the touch panel 500TP. For example, the area 500TP_ shown in FIG.
The touch sensor 600 provided in No. 2 is driven, but the touch sensor 600 provided in the region 500TP_1 is not driven. Note that, as described above, FIG. 4C is a diagram showing a state in which the touch panel 500TP shown in FIG.

Further, it is not necessary to drive the entire region of the touch panel 500TP that is not wound by the winding unit 106. In other words, the range in which the touch sensor 600 is driven may be adjusted in the region of the touch panel 500TP that is not wound by the winding unit 106. For example, in the configuration in which the winding unit 106 is provided in the housing 105, the area of the touch panel 500TP housed in the housing 105 may be wider than the area of the touch panel 500TP wound by the winding unit 106. .. For example, when the housing 108 is provided with a roller 108 or the like,
The touch panel 500 is provided so as to avoid the area where the roller 108 and the like touch the touch panel.
The range in which the touch sensor 600 is driven may be determined in the area not wound by the winding section 106 of the TP. Further, the drive unit 103 drives the touch sensor 600 provided in a region of the touch panel 500TP which is not housed in the housing 105, and the touch panel 500T.
It is not necessary to drive the touch sensor 600 provided in the area housed in the P casing 105. For example, the touch sensor 600 included in the region 500TP_4 illustrated in FIG. 6B is driven and the touch sensor 600 included in the region 500TP_3 is not driven. In addition, the driving unit 103 may determine a region where the touch sensor 600 is driven and a region where the touch sensor 600 is not driven, based on the detection element 104a. For example, the touch sensor 600 included in the region 500TP_6 illustrated in FIG. 6D is driven and the touch sensor 600 included in the region 500TP_5 is not driven.

The details of the method of driving the touch sensor 600 by the driving unit 103 will be described in the third embodiment.

Further, it drives the display unit 500 provided in the region not wound by the winding unit 106 of the touch panel 500TP, and drives the display unit 500 provided in the region wound by the winding unit 106 of the touch panel 500TP. You don't have to.

The display area of the display unit 500 can be limited based on the first information related to the area wound by the winding unit 106 of the touch panel 500TP supplied from the detection unit 104. Alternatively, the display area of the display unit 500 can be limited based on the second information about the area wound by the winding unit 106 of the touch panel 500TP supplied from the calculation unit 110. For example, only the display unit 500 provided in the region not wound by the winding unit 106 of the touch panel 500TP is driven. Alternatively, only the display unit 500 provided in the area of the touch panel 500TP that is not housed in the housing 105 is driven.

When limiting the area for driving the display unit 500, the winding unit 10 of the touch panel 500TP.
The image may be transformed so that the entire image can be seen in the area that is not rolled up by 6. Further, the image does not have to be displayed on the entire display unit provided in the area not wound by the winding unit 106 of the touch panel 500TP. Further, the display area may be changed according to the aspect ratio of the image. Further, the orientation of the image may be changed. For example, the image may be rotated by 90 degrees and displayed in order to display the image to the maximum extent. For example, when the horizontal width of the original image is longer than the vertical length, but the horizontal width of the display area is shorter than the vertical length, the image can be displayed larger by rotating the image 90 degrees. In addition, the orientation of the image is the orientation of the touch panel MEMS (
The image may be detected by a sensor such as a microelectromechanical system, and the image may be converted so that the upper side of the information processing apparatus 100 and the upper side of the image which are determined in advance are aligned. Further, when converting an image so that the entire image can be viewed, it is preferable to limit the display area so as to match the aspect ratio of the original image. Further, the display area may be limited to the number of pixels and the area in which it is easy to convert the image.

When the display area is changed, the area for driving the touch sensor 600 may be changed according to the display area.

For example, the touch sensor 600 of the touch panel 500TP can detect the detection information and supply the detection information together with the position information. Specifically, the user of the touch panel 500TP can perform various gestures (tap, drag, swipe, pinch-in, etc.) by using a finger or the like that is close to or in contact with the touch sensor 600 as a pointer.

The touch sensor 600 can detect a finger or the like that is in proximity to or in contact with the touch sensor 600, and can supply detection information including the detected position or locus.

The arithmetic unit determines whether the supplied information satisfies a predetermined condition based on a program or the like, and executes a command associated with a predetermined gesture.

Has 00.

Note that an example of a method for manufacturing a stacked body which can be applied to manufacturing the touch panel 500TP is described in detail in Embodiments 4 to 6.

《Touch sensor》
The touch sensor 600 includes a control line CL (i), a signal line ML (j) or a flexible substrate 610.

Note that the touch sensor 600 may be manufactured by a method of forming a film for forming the touch sensor 600 on the flexible substrate 610 and processing the film.

Alternatively, the touch sensor 600 may be manufactured by a method in which part of the touch sensor 600 is formed on another base material and the part is transferred to the flexible substrate 610.

The touch sensor 600 detects a proximity or a contact and supplies a detection signal. For example, capacitance, illuminance, magnetic force, radio waves or pressure are detected, and information based on the detected physical quantity is supplied. Specifically, a capacitive element, a photoelectric conversion element, a magnetic sensing element, a piezoelectric element, a resonator, or the like can be used as the sensing element of the touch sensor 600.

As the touch sensor 600, for example, a capacitance method, a resistance film method, an optical method, a surface acoustic wave method, an electromagnetic induction method, or the like can be used. Capacitive touch sensor,
It is classified into a projection type and a surface type, and the projection type is further classified into a self-capacitance method and a mutual capacitance method.
Further, as the touch sensor 600, an active matrix method using an active element such as a transistor can be used.

For example, the capacitance type touch sensor detects a change in capacitance between a detected object such as a finger or a stylus pen and a conductive film included in the touch sensor 600. In the case of the mutual capacitance method which is one of the projected electrostatic capacitance methods, for example, the extending direction of the control line and the first electrode electrically connected thereto, and the signal line and the second direction electrically connected thereto The extending directions of the electrodes of are intersected. At the intersection, the control line and the first electrode are separated from the signal line and the second electrode by an insulator. Therefore, a mutual capacitance is generated between the control line or the first electrode and the signal line or the second electrode near the intersection. In addition, the detected object is a control line, a first electrode, a signal line,
Alternatively, when it comes close to the second electrode, an electrostatic capacitance is generated between the object to be detected and them.

When an AC voltage or a pulsed voltage is applied to the control line, a current flows in the signal line depending on the mutual capacitance at the intersection. However, when the object to be detected approaches the intersection and electrostatic capacitance occurs, the current is affected by the electrostatic capacity in addition to the mutual capacitance.Therefore, the value of the current flowing through the signal line is Change compared to when not. Therefore, the current flowing through the signal line can be used as the detection signal. Further, when a plurality of control lines and signal lines are provided, if a voltage is sequentially supplied to the plurality of control lines, a current sequentially flows through the plurality of signal lines. It is possible to detect the position of the intersecting portion where the detected object is in close proximity, based on the amount of change in the current flowing through the plurality of signal lines and the timing at which the current flows. Therefore, it is possible to detect the position of the object to be detected that is close to or in contact with the touch sensor 600.

If the area 107 is the same as the edge of the touch panel 500TP, the touch panel 5 is displayed in the area 107.
00TP is fixed to the winding unit 106. Even when the end of the touch panel 500TP does not match the end of the touch sensor 600, the touch panel 500TP is fixed to the winding unit 106 in the region 107_2 outside the region 107, as shown in FIG. Therefore, the direction in which the touch panel 500TP is wound around the winding unit 106 is the direction indicated by the arrow C.

In this configuration example, the direction in which the touch panel 500TP is wound around the winding unit 106 intersects the direction in which the control line extends.

The direction in which the touch panel 500TP is wound around the winding unit 106 preferably intersects the direction in which the control line extends perpendicularly. With the above configuration, the touch panel 500
It becomes difficult for the control line to be partially provided in the region wound by the winding unit 106 of the TP. This is because in the above configuration, the boundary line between the wound area and the unwound area is parallel to the control line.

For example, rectangular electrodes can be used for the first electrode C1 (i) and the second electrode C2 (j) (see FIG. 14A). Note that when a light-transmitting conductive film is used, a light-transmitting touch sensor can be provided.

For example, a rectangular first electrode C1 (i) and a second electrode C2 (j) each having an opening so as to have a mesh shape can be used (FIG. 14B or FIG. See C)). Note that when a metal film or the like provided with an opening is used, electric resistance can be reduced as compared with the case where a conductive film having a light-transmitting property is used. With this, it is possible to provide a touch sensor having various sizes having translucency, and it is possible to supply the detection information without depending on the size. For example, it is possible to provide touch sensors of various sizes from a size that can be used for a handheld type to a size that can be used for an electronic blackboard.

<< Method of Driving Touch Sensor in Configuration Example 1 >>
In the following, in the touch panel 500TP of the configuration example 1, the drive unit 103 includes the touch sensor 6
00 shows a method for driving a part of 00. Specifically, the touch panel 500TP is the winding unit 1.
When a part of the touch panel 500TP is wound, the touch sensor 600 provided in an area not wound by the winding portion of the touch panel 500TP is driven to be provided in an area wound by the winding portion of the touch panel 500TP. A method of not driving the touch sensor 600 will be described with reference to FIG.
This will be described using (A) and the like.

The detection unit 104 supplies the first information regarding the state of the touch panel 500TP to the drive unit. Specifically, the detection unit 104 supplies the drive unit 103 with the first information on the region wound by the winding unit 106 of the touch panel 500TP.

Note that, as shown in FIG. 15A, the detection unit 104 supplies the first information related to the state of the touch panel 500TP to the arithmetic unit 110, and the arithmetic unit 110 detects the touch panel 500TP based on the first information. The configuration may be such that the second information regarding the state is calculated. The second information regarding the state of the touch panel 500TP calculated by the calculation unit 110 is supplied to the drive unit 103. Specifically, the detection unit 104 supplies the calculation unit 110 with the first information related to the region wound by the winding unit 106 of the touch panel 500TP, and the calculation unit 110 touches the touch panel based on the first information. The second information related to the region wound by the winding unit 106 of 500TP is calculated. The second information, which is calculated by the calculation unit 110 and is related to the region wound by the winding unit 106 of the touch panel 500TP, is supplied to the driving unit 103.

The control unit 103C of the drive unit 103 supplies a control signal. For example, the control unit 103C sequentially supplies the control signal to each control line. Alternatively, a plurality of signals that are modulated by a method capable of being separated by the output unit 103D are supplied to a plurality of control lines at the same time.

However, based on the first information or the second information of the area wound by the winding section 106 of the touch panel 500TP supplied to the driving section 103, the area not wound by the winding section 106 of the touch panel 500TP is set. The control signal is supplied to the provided control line, and the control signal is not supplied to the control line provided in the region wound by the winding unit 106 of the touch panel 500TP. For example, when the control lines CL (1) to CL (k1) are provided in the region wound by the winding unit 106 of the touch panel 500TP, control signals are supplied to the control lines CL (k1 + 1) to CL (m). The control signal is supplied to the control lines CL (1) to CL (k1). Here, k1 is a natural number of 1 or more and m-1 or less. It should be noted that even if a part of the control line is provided in the region wound by the winding unit 106 of the touch panel 500TP, no control signal is supplied to the control line. Further, it is not necessary to supply the control signal to all the control lines CL (k1 + 1) to CL (m), and it is possible to select them as needed. Specifically, for example, when the roller 108 or the like contacts the control line CL (i), the control signal does not have to be supplied to the control line CL (i).

When a detection object such as a finger or a stylus pen approaches a conductive film such as the control line CL (i1) or the first electrode C1 (i1) electrically connected to the control line CL (i1), the detection object is detected. And the capacitance between the conductive film changes. Here, i1 is a natural number of (k1 + 1) or more and m or less. In addition, since the detected object comes close to the conductive film such as the signal line ML (j) or the second electrode C2 (j) electrically connected to the signal line ML (j), the detected object and these conductive objects The capacitance between the membranes also changes. Then, the detection signal changes based on the change in the capacitance.

The output unit 103D is supplied with the detection signal. The detection signal changes as the detected object approaches the first electrode and the second electrode. The touch sensor 600 can know the proximity or contact of the detected object based on whether or not the change of the detection signal exceeds a threshold value, for example. The above operation can be restated as touch detection.

With the above driving method, erroneous detection of the touch sensor 600 included in the information processing apparatus 100 can be prevented. Further, since the number of control lines for supplying the control signal can be reduced, power consumption can be reduced.

<Modification of Configuration Example 1 of Touch Sensor>
The detection signal passes through the signal line and the second electrode and is supplied to the output section. In the configuration of FIG. 12A, since the touch panel 500TP is wound from the side closer to the output unit, the detection signal includes the signal line and the first signal line provided in the region wound by the winding unit 106 of the touch panel 500TP. Through electrode 2.

On the other hand, the touch sensor 600 may have a structure in which the wiring portion 112 is rotated around as shown in FIG. As a result, the detection signal is supplied to the output unit 103D without passing through the second electrode provided in the region wound by the winding unit 106 of the touch panel 500TP.

Alternatively, as shown in FIG. 17A, the driving unit 103 may be provided in a direction different from the direction in which the winding unit 106 is provided. Thereby, the detection signal is supplied to the output unit 103D without passing through the signal line and the second electrode provided in the region wound by the winding unit 106 of the touch panel 500TP. In the configuration of FIG. 17A, for example, the driving portion can be provided in a handle.

<Touch sensor configuration example 2>
The configuration example 2 is different from the configuration example 1 in the positional relationship between the control line and the signal line and the winding unit 106. Structural example 2 will be described with reference to FIG.

FIG. 12B illustrates a top view and a block diagram of the touch sensor 600 of Structural Example 2. 12B shows the state in which the touch sensor 600 is expanded in a plane for the sake of explanation, a part of the touch panel 500TP is wound around the winding unit 106 by using FIG. 12B. The driving method in the taken state may be described.

The drive unit 103 includes a control unit 103C and an output unit 103D. The control unit 103C supplies a control signal. Further, the output unit 103D is supplied with the detection signal. The detection signal includes information regarding the position of the touch sensor with which the detection target such as a finger or a stylus pen approaches or contacts.

The control line is supplied with a control signal and extends in the direction indicated by arrow C in the figure.

The signal line extends in the direction indicated by the arrow R in the figure and supplies a detection signal.

It is electrically connected to the output unit 103D via C1. Although the wiring portion 112 is provided along one side of the touch sensor 600 in FIG. 12B, the wiring portion 112 may be provided on the opposite side in addition to this.

The touch panel 500TP and the winding unit 106 are fixed in the direction of the side of the area 107 of the touch sensor. For example, the edge of the touch panel 500TP and the edge of the touch sensor 600 are aligned,
If the area 107 becomes the end of the touch panel 500TP, the touch panel 500T is displayed in the area 107.
P is fixed to the winding unit 106. Even when the edge of the touch panel 500TP does not coincide with the edge of the touch sensor 600, as shown in FIG. 13B, the touch panel 500TP is fixed to the winding portion 106 in the area 107_2 outside the area 107. Therefore, the direction in which the touch panel 500TP is wound around the winding unit 106 is the direction indicated by the arrow C.

In this configuration example, the direction in which the touch panel 500TP is wound around the winding unit 106 intersects the direction in which the signal line extends.

In addition, it is preferable that the direction in which the touch panel 500TP is wound around the winding unit 106 intersects with the direction in which the signal line extends perpendicularly. With the above structure, a part of the signal line exists in the region wound by the winding unit 106, and another part of the signal line exists in the region not wound by the winding unit 106. It becomes difficult to be in the state of doing.

The first information related to the area wound up on the sheet is supplied to the drive unit 103.

As shown in FIG. 15B, the detection unit 104 supplies the first information regarding the state of the touch panel 500TP to the arithmetic unit 110, and the arithmetic unit 110 detects the touch panel 500TP based on the first information. The configuration may be such that the second information regarding the state is calculated. The second information regarding the state of the touch panel 500TP calculated by the calculation unit 110 is supplied to the drive unit 103. Specifically, the detection unit 104 supplies the calculation unit 110 with the first information related to the region wound by the winding unit 106 of the touch panel 500TP, and the calculation unit 110 touches the touch panel based on the first information. The second information related to the region wound by the winding unit 106 of 500TP is calculated. The second information, which is calculated by the calculation unit 110 and is related to the region wound by the winding unit 106 of the touch panel 500TP, is supplied to the driving unit 103.

The control unit 103C of the drive unit 103 supplies a control signal to the control lines CL (1) to CL (m). For example, the control unit 103C sequentially supplies the control signal to each control line CL (i).
Alternatively, the plurality of signals modulated by the method capable of being separated by the output unit 103D are supplied to the plurality of control lines CL (i) at the same time.

When a detected object such as a finger or a stylus pen approaches a conductive film such as the control line CL (i) or the first electrode C1 (i) electrically connected to the control line CL (i), the detected object is detected. And the capacitance between the conductive film changes. In addition, the signal line ML (j) and the second line electrically connected to the signal line ML (j)
When the detected object comes close to the conductive film such as the electrode C2 (j), the electrostatic capacitance between the detected object and these conductive films also changes. Then, the detection signal changes based on the change in the capacitance.

The output unit 103D is supplied with the detection signal. The detection signal changes as the detected object approaches the first electrode and the second electrode. The output unit 103D can detect the proximity of the detection target to the conductive film, for example, based on whether or not the change in the detection signal exceeds a threshold value. In addition, the touch sensor 600 can know the position on the touch sensor 600 where the detection target is in proximity or in contact.

However, the signal line ML provided in the region not wound by the winding unit 106 of the touch panel 500TP based on the first information related to the region wound by the winding unit of the touch panel 500TP supplied from the detection unit. The detection information supplied from (j) is used, and the detection information supplied from the signal line ML (j) provided in the region wound by the winding unit 106 of the touch panel 500TP is not used. For example, the winding unit 106 of the touch panel 500TP
When the signal lines ML (1) to ML (k2) are provided in the region wound up by the signal lines ML (k2 + 1) to ML (n), the detection information supplied from the signal lines ML (k2 + 1) to ML (n) is used. 1)
To the detection information supplied from ML (k2) are not used. Here, k2 is a natural number of 1 or more and n-1 or less. Note that it is not necessary to use all the detection information supplied from the signal lines ML (k2 + 1) to ML (n), and it is possible to select as necessary. Specifically, for example, when the roller 108 or the like contacts the signal line ML (k2 + 1), the detection information of the signal line ML (k2 + 1) does not have to be used.

With the above driving method, erroneous detection of the touch sensor 600 included in the information processing apparatus 100 can be prevented.

As a result, it is possible to provide a novel touch sensor that is highly convenient or reliable.

For example, a control signal that can be separated from the first control signal may be used as the second control signal. Specifically, a signal having the first frequency can be used as the first control signal, and a signal having the second frequency different from the first frequency can be used as the second control signal.

In this configuration example, it is possible to combine the configurations described in the configuration example 1 or the configuration example 2 with the above configuration.

Further, when the layer to be peeled is peeled from the peeling layer S2, the liquid is permeated into the interface between the peeling layer S2 and the layer to be peeled S3. Alternatively, the liquid may be ejected from the nozzle 99 and sprayed. For example, water, a polar solvent, or the like can be used as the liquid to be permeated or the liquid to be sprayed.

By allowing the liquid to permeate, it is possible to suppress the influence of static electricity or the like generated due to the peeling. Alternatively, the peeling layer may be peeled off while permeating a liquid that dissolves the peeling layer.

In particular, when a film containing tungsten oxide is used for the peeling layer S2, if the first peeled layer S3 is peeled while infiltrating or spraying a liquid containing water, the stress caused by peeling applied to the first peeled layer S3 Can be reduced, which is preferable.

A method for manufacturing a laminate having the same steps except that the second support 42 is replaced by a second support 42b smaller than the first support 41b in the ninth step. Is. Accordingly, a stacked body in which part of the second layer to be separated S3 is exposed can be manufactured (see FIGS. 21A-1 and 21A-2).

A liquid adhesive can be used for the second adhesive layer 32. Alternatively, an adhesive agent (also referred to as a sheet-like adhesive agent) whose fluidity is suppressed and which is previously molded into a sheet shape can be used. If a sheet-shaped adhesive is used, the amount of the adhesive layer 32 protruding outside the second support 42b can be reduced. Moreover, the thickness of the adhesive layer 32 can be easily made uniform.

Further, the exposed portion of the second layer to be peeled S3 may be cut off so that the first layer to be peeled F3 is exposed (see FIGS. 21B-1 and 21B-2). ).

Specifically, a scratch is formed on the exposed second layer to be peeled S3 by using a blade or the like having a sharp tip. Then, for example, an adhesive tape or the like is attached to a part of the exposed second peeled layer S3 so that stress is concentrated near the scratch, and the second peeled layer S is attached together with the attached tape or the like.
A part of 3 can be peeled off, and that part can be selectively excised.

In addition, a layer that can suppress the force of bonding the bonding layer 30 to the first peeled layer F3 is
It may be selectively formed on a part of the peeled layer F3. For example, a material that does not easily adhere to the bonding layer 30 may be selectively formed. Specifically, the organic material may be vapor-deposited in an island shape. Thereby, a part of the bonding layer 30 can be selectively and easily removed together with the second layer to be peeled S3. As a result, the first peeled layer F3 can be exposed.

Note that, for example, the first peeled layer F3 is a functional layer and a conductive layer F3 electrically connected to the functional layer.
b), the conductive layer F3b can be exposed in the opening of the second stacked body 92c. Thereby, for example, the conductive layer F3b exposed in the opening can be used as a terminal to which a signal is supplied.

As a result, the conductive layer F3b partially exposed in the opening can be used as a terminal from which a signal supplied by the functional layer can be extracted. Alternatively, a signal supplied with the functional layer can be used for a terminal to which an external device can supply.

<< Example 2 of manufacturing method of laminate having opening in support >>
A mask 48 having an opening provided so as to overlap with an opening provided in the second support body 42 is formed in the stacked body 92. Then, the solvent 49 is dropped into the opening of the mask 48. Accordingly, the second support 42 exposed in the opening of the mask 48 can be swollen or dissolved using the solvent 49 (see FIGS. 21C-1 and 21C-2).

After removing the excess solvent 49, the second support 42 exposed in the opening of the mask 48 is rubbed or the like to apply stress. As a result, the portion of the second support 42 and the like that overlaps the opening of the mask 48 can be removed.

If a solvent that swells or dissolves the bonding layer 30 is used, the first peeled layer F3 can be exposed (see FIGS. 21D-1 and 21D-2).

Note that this embodiment can be combined with any of the other embodiments in this specification as appropriate.

In this example, a bendable touch panel of one embodiment of the present invention was manufactured. In addition, in the present embodiment, a result of performing a sensing test on the touch panel in a bent state will be described.

[Fabrication of touch panel]
In this example, an in-cell type touch panel was manufactured in which a touch sensor was built in a counter substrate (substrate on the display surface side) of a flexible display panel. Further, the electrodes of the touch sensor are formed in a mesh shape (also referred to as a metal mesh shape) so that the load capacitance between the touch sensor and the display panel is reduced. With such a configuration, the thickness of the entire touch panel can be reduced to the extent that the user can freely fold it. Further, since the load capacitance is small, the influence of noise from the display panel on the touch sensor is suppressed, and it is possible to suppress the occurrence of problems such as erroneous detection and non-detection.

As a driving method of the in-cell type touch panel manufactured in this example, a mutual capacitance method, which is one of the projected capacitance methods, was adopted.

FIG. 23A shows the structure of the touch panel manufactured in this example. A schematic diagram of the touch panel is shown in the center of FIG. 23A, a sectional structure of the touch panel is shown on the left side, and an enlarged view of a bent portion of the touch panel is shown on the right side. The touch panel includes a flexible display portion (denoted as Display) and an FPC. The touch panel has a structure in which two flexible substrates are bonded together by an adhesive layer. In addition, a passivation layer is provided on each surface of the flexible substrate that faces each other. On one of the flexible substrates, a FET layer and an organic EL element (denoted as OLED) are formed on the passivation layer. On the other flexible substrate, a touch sensor and a color filter are formed on the passivation layer. As shown in FIG. 23A, the touch panel manufactured in this example can be bent so that the display surface has a convex shape and can be bent so as to have a concave shape.

FIG. 23B shows a more specific cross sectional structure. On one flexible substrate side,
Partitions (denoted as Partition) are provided on both ends of the organic EL element, and spacers are provided on the partition. On the surface of the other flexible substrate on the organic EL element side, a black matrix is formed on the passivation layer, and a sensor electrode (Sensor metal) forming a touch sensor is formed.
,), A bridge electrode (Bridge metal), and a color filter are sequentially formed. The color filter is arranged so as to overlap the organic EL element. An insulating layer (Intemet) is provided between each of the black matrix, the sensor electrode, the bridge electrode, and the color filter.
r layer). Each of the sensor electrode and the bridge electrode is arranged so as to overlap the black matrix. By disposing the black matrix on the display surface side of the sensor electrode and the bridge electrode, it is possible to suppress reflection of external light due to these. Further, by arranging the sensor electrode and the bridge electrode inside the width of the black matrix, it is possible to minimize the influence on the aperture ratio (light extraction efficiency).

To manufacture a touch panel, first, a peeling layer, a passivation layer, an FET layer,
An organic EL device was formed.

As a transistor included in the FET layer (corresponding to the transistor 502t), a transistor including an oxide semiconductor as a semiconductor in which a channel is formed is used. Here, in this embodiment, as an oxide semiconductor, a crystalline oxide semiconductor (CAAC-OS: C-Axis) in which a c-axis is oriented in a direction substantially perpendicular to a film surface and a crystal grain boundary in the film surface direction is not confirmed. Aligned
Crystalline-Oxide Semiconductor) was used.

The CAAC-OS is a crystalline oxide semiconductor in which the c-axis of crystals is approximately vertical to the film surface. Since the CAAC-OS has a feature that crystal grain boundaries are not confirmed, a stable and uniform film can be formed over a large area, and the stress caused when the flexible light-emitting device is bent causes the CAAC-OS. Cracks are less likely to occur in the OS film.

In this example, an In—Ga—Zn-based oxide was used as the oxide semiconductor material.

As the pixel electrode (lower electrode), an alloy containing silver having an extremely high reflectance was used. In addition, a transparent electrode layer (also referred to as an optical adjustment layer) having an appropriate thickness was formed over the pixel electrode so that a microcavity effect was obtained depending on the structure of the subpixel.

A top emission type white EL element was used as the organic EL element. The organic EL element had a tandem structure in which a blue light emitting unit and a yellow light emitting unit were stacked.

Further, a peeling layer, a passivation layer, a black matrix, a sensor electrode, a bridge electrode, a color filter, and an insulating layer therebetween were formed over a glass substrate different from the above.

Subsequently, the two substrates were bonded together with an adhesive layer. Distance between substrates at this time (cell gap)
Was adjusted to about 5 μm. After that, each substrate was peeled between the peeling layer and the passivation layer, and a flexible substrate was attached. As a flexible substrate, thickness is about 20 μm
The plastic substrate of was used.

The touch panel was produced as described above. The specifications of the touch panel are as follows: the size of the display is 8.67 inches diagonal, the number of pixels is 1080 × RGBY × 1920, and the definition is 254 ppi.
The aperture ratio is about 46%. As the touch sensor, a mesh-shaped sensor electrode was used, and 48 transmission electrodes were formed in the long side direction of the display portion and 27 reception electrodes were formed in the short side direction. Moreover, each space | interval was 4 mm. In the touch sensor, a region of 40 × 40 pixels included in the display portion corresponds to one unit of the touch sensor.

It was confirmed that the manufactured touch panel could display normally both when the display surface was made flat and when it was bent to a convex shape and when it was bent to a concave shape. Furthermore, it was confirmed that normal detection can be performed in each of the flat surface portion, the convex portion, and the concave portion of the surface of the touch panel.

[Evaluation of parasitic resistance / capacitance at bending part]
The effect of bending the fabricated touch panel on the parasitic capacitance and the parasitic resistance between the receiving electrode and the display panel was evaluated.

The measurement was performed in three ways: a state in which the display surface of the touch panel was flat, a state in which it was bent in a convex shape, and a state in which it was bent in a concave shape. Further, when the radius of curvature R was 10 mm, two types were examined when the radius of curvature R was 5 mm.

The measurement was performed using an LCR meter (4275A, manufactured by Agilent Technologies, Inc.).

FIG. 24 shows the rate of change of the parasitic resistance and the parasitic capacitance in the bent state with reference to the state where the display surface is flat. The number of measurements is 6. As shown in FIG. 24, the display surface is bent in a convex shape (denoted by Outside bend) and the display surface is bent in a concave shape (inside).
In any state of “bend” and a state where the radius of curvature is 5 mm,
It was confirmed that the fluctuation rates of the parasitic resistance and the parasitic capacitance were less than 0.1%, which were extremely small. From this result, it was confirmed that the influence of bending the touch panel on the detection sensitivity was extremely small.

Below, the results of examining the influence on the light extraction efficiency by providing the electrodes of the touch sensor will be described.

Since the touch panel manufactured in Example 1 uses a top emission type light emitting element, light from the light emitting element is extracted through the substrate on the opposite side. Therefore, both a flexible substrate on which the touch sensor electrode is formed and a flexible substrate on which the touch sensor electrode is not formed are manufactured, and the light transmittance thereof is measured.

25 (A), (B), and (C) show schematic sectional views of the measuring method and the manufactured sample.

FIG. 25A corresponds to a measurement system that directly measures the brightness of light from a reference light source. Figure 25
(B) corresponds to a measurement system for measuring a sample (expressed as w / metal mesh) on which a mesh-shaped sensor electrode is formed. For comparison, FIG. 25C corresponds to a measurement system that measures a sample (described as w / o metal mesh) in which a mesh-shaped sensor electrode or the like is not formed.

The sample shown in FIG. 25B is the same as the sample shown in FIG. 23B except that the position of the flexible substrate is different from the layered structure which is an upper layer than the color filter. In FIG. 25B, the flexible substrate is attached to the color filter side with an adhesive layer in between.

The sample shown in FIG. 25C has a structure in which a black matrix and a color filter are formed over a passivation layer, and this and a flexible substrate are attached to each other with an adhesive layer interposed therebetween.

In the measurement, the sample was placed on a surface light source, and the brightness of light passing upward through the sample was measured by a measuring instrument. The number of measurements is 12. An edge type backlight (MEBL-CW145 manufactured by Shot Moritex Co., Ltd.) was used as the surface light source. A color luminance meter (BM-5AS manufactured by Topcon Techno House Co., Ltd.) was used as a measuring instrument.

When each sample was placed on the surface light source and compared, the difference could not be visually confirmed. Figure 2
6 shows the measurement results. FIG. 26 shows 100 when the sample is not placed (FIG. 25 (A)).
%, And the luminance measured for each sample is shown as the transmittance. It was confirmed that the sample having the mesh-shaped sensor electrode had a transmittance of about 16.0%, and the sample having no sensor electrode had a transmittance of about 16.3%, showing almost no difference. The slightly low transmittance of the sample having the mesh-shaped sensor electrode is considered to be due to the difference in the laminated structure.

From the above, it was confirmed that the touch sensor of one embodiment of the present invention hardly affects the light extraction efficiency.
