Currently, resistive and capacitive touch screen technologies are widely used.

Mutual capacitive touch screen, with its high sensitivity and advantages of multi-touch, is becoming more and more popular. The basic principle of mutual capacitive touch screen is: apply voltage on the drive line side, and detect signal changes on the detection line side . The driving line determines the coordinates in the X direction, and the detection line determines the coordinates in the Y direction. During detection, the X-direction driving lines are scanned row by row. When scanning each row of driving lines, the signals on each detection line are read. After one round of scanning, the intersection points of each row and column can be scanned to , to scan X*Y signals in total. This detection method can specifically determine the coordinates of multiple points, so it can realize multi-point touch.

The driving method of the capacitive touch screen commonly used at present is a time-sharing driving method, that is, the display driving (display) and the touch signal detection driving (touch) are performed step by step.

Detailed ways

In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the utility model. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the described embodiments of the present invention belong to the protection scope of the present invention.

Unless otherwise defined, the technical terms or scientific terms used herein shall have the usual meanings understood by those skilled in the art to which the present invention belongs. "First", "second" and similar words used in the utility model patent application specification and claims do not indicate any order, quantity or importance, but are only used to distinguish different components. Likewise, words like "a" or "one" do not denote a limitation in quantity, but indicate that there is at least one. Words such as "connected" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "Down", "Left", "Right" and so on are only used to indicate the relative positional relationship. When the absolute position of the described object changes, the relative positional relationship also changes accordingly.

The embodiment of the present invention provides a touch display device, including a first substrate 1, as shown in FIG. A matrix row in the matrix of touch driving electrode blocks corresponds to at least one grid line within the projected area on the first substrate, and each column in the matrix of touch driving electrode blocks includes a first touch driving electrode block 41 and a second touch driving electrode block. Control drive electrode blocks 42, the second touch drive electrode blocks 42 in different matrix columns belong to different matrix rows;

As shown in Figures 1 and 6, the first substrate may specifically include:

A plurality of first touch drive signal transmission lines 5 (TXn) corresponding to each column in the touch drive electrode block matrix, the first touch drive signal transmission lines 5 and the first touch drive electrode blocks 41 in the corresponding matrix columns Electrically connected, used to sequentially transmit the first touch driving signal to the first touch driving electrode block 41 in the corresponding matrix column within a display time period; wherein, the first touch driving signal receiving the first touch driving signal The gate line 9 corresponding to the electrode block 41 is in the closed state, and when the gate line 9 corresponding to the first touch driving electrode block 41 in a matrix column is in the closed state, the second touch driving electrode block 42 in the matrix column is in the closed state. The corresponding gate line 9 is in an open state;

The second touch drive signal transmission line 6 (TX-add) is connected to the second touch drive electrode blocks 42 in all matrix columns in the touch drive electrode block matrix, and is used to transmit all signals between adjacent display time periods. The second touch driving electrode blocks 42 in the matrix column transmit the second touch driving signal.

The touch display device provided by the embodiment of the present invention, through the above-mentioned configuration, can drive the grid lines 9 corresponding to the matrix rows in a matrix of electrode blocks in a touch control (usually, a matrix row on the first substrate A plurality of pixel rows may be included in the projected area, therefore, in the embodiment of the present invention, a matrix row may correspond to at least one gate line 9) When it is in an on state, it does not connect to the first grid line connected to the touch drive electrode block in the matrix row. A touch driving signal transmission line 5 sends the first touch driving signal, but sends the corresponding first touch driving signal to other first touch driving signal transmission lines 5 not connected to the touch driving electrode block in the matrix row, Therefore, within one display period (for example, one frame time), display driving and touch detection can be realized synchronously. Compared with the existing time-sharing driving control method, the time of touch detection can be extended, and the touch detection time can be reduced. The transmission frequency of the detection signal reduces the internal noise of the touch display device and improves the display quality of the touch display device.

At the same time, in order to avoid the omission of touch detection, the touch display device provided by the embodiment of the present invention can also drive the second touch in all matrix columns between two adjacent display periods. The second touch drive signal transmission line 6 connected to the electrode block 42 (that is, the touch drive electrode block that is not synchronized with the display drive for touch detection) sends the second touch drive signal to realize the second touch drive electrode block. 42 to detect the touch operation in the corresponding touch area. Since the second touch driving signal transmission line 6 is connected to the second touch driving electrode blocks 42 in all matrix columns, only at least one second touch driving signal transmission line 6 can transmit the second touch detection signal once. , the touch detection of all the second touch driving electrode blocks 42 can be realized, so the touch detection of the second touch driving electrode blocks 42 will not take a long time, and will not affect the touch display device. Normal display is affected.

Moreover, due to the above-mentioned structural settings, in the touch display device provided in the embodiment of the present invention, the gate lines 9 intersected with the touch signal transmission lines (including the first touch drive signal transmission line 5 and the second touch control signal transmission line 5 and the second touch control signal transmission line The driving signal transmission line 6) does not transmit the driving signal at the same time, so signal interference between the gate line 9 and the touch signal transmission line can be avoided, which further improves the display quality of the touch display device.

The touch display device provided by the embodiment of the present invention, as shown in FIG. 2 , may specifically include a touch display area 7 .

In order to correspond to the structural settings of existing touch display devices such as mobile phones, in the embodiment of the present utility model, the touch display area 7 can be specifically configured as a vertical screen structure, that is, as shown in FIG. The length y value of the column direction of the control driving electrode block matrix is greater than the length x value of the touch display area 7 in the row direction of the touch driving electrode block matrix. Of course, the touch display area 7 involved in the embodiment of the present invention can also be a horizontal screen structure, or any geometric shape and corresponding structure.

Then, it can be seen from the structure shown in FIG. 2 that the arrangement positions of the plurality of common electrodes 3 and the matrix of touch driving electrode blocks involved in the embodiment of the present invention are located in the touch display area 7 .

At the same time, it can be seen from FIG. 2 that the plurality of common electrodes 3 included in the first substrate 1 according to the embodiment of the present invention can be arranged at intervals with the matrix rows of the touch driving electrode block matrix and extend in the same direction.

The touch display device provided by the embodiment of the present utility model, as shown in FIG. Color film substrate.

In the second substrate 2 involved in the embodiment of the present utility model, it may specifically include a plurality of detection electrodes 8 (RX), and the setting position of the detection electrodes 8 in the second substrate may be specifically related to the setting of the common electrode 3 in the first substrate. The positions are the same, specifically as shown in FIG. 3 , that is, the two are arranged to overlap in space.

In the embodiment shown in FIG. 1 , the touch driving signal transmission lines (the first touch driving signal transmission line 5 and the second touch driving signal transmission line 6 ) lead out from the left side of the touch display area 7 to the touch display area 7 . But in fact, the touch drive signal transmission line can lead out from at least one side of the touch display area 7, the left and right sides as shown in FIG. 4, and the bottom side as shown in FIG. The intersecting touch driving signal transmission lines can be provided with a shielding insulation layer on the two touch driving signal transmission lines).

In a specific embodiment, in order to avoid the intersection of the touch drive signal transmission line and the gate line 9, in the embodiment of the present utility model, the touch display area 7 leads to the sides of a plurality of touch drive signal transmission lines, which are connected with the gate line 9. In the touch display area 7, the grid lines 9 are introduced into one side opposite to the other side. As shown in Figure 6, when the gate line 9 is introduced into the touch display area 7 from the left side of the touch display area 7, in the embodiment of the present invention, the touch drive signal transmission line can be drawn out of the touch control display area from the right side of the touch display area. Control the display area 7, so as to fundamentally solve the mutual interference between the gate line 9 and the touch driving signal transmission line.

Next, a specific embodiment of the touch display device provided by the present invention will be described in detail.

In this embodiment, as shown in FIG. 7 , the touch drive electrode block matrix may specifically include N matrix rows and M matrix columns, and both N and M are positive integers greater than or equal to 2.

In the M matrix columns, the touch driving electrode block located in the Nth matrix row is the second touch driving electrode block 42 , and the touch driving electrode blocks located in other matrix rows are the first touch driving electrode block 41 .

For example, as shown in FIG. 7, in the first matrix column, the touch drive electrode blocks located in the first matrix row are the second touch drive electrode blocks 42, and in the first matrix column, except for the touch drive electrode blocks located in the first matrix row The touch driving electrode blocks other than the touch driving electrode blocks are the first touch driving electrode blocks 41; in the second matrix column, the touch driving electrode blocks located in the second matrix row are the second touch driving electrode blocks 42, In the second matrix column, the touch driving electrode blocks except the touch driving electrode blocks located in the second matrix row are all the first touch driving electrode blocks 41; The touch driving electrode blocks in the N matrix rows are the second driving electrode blocks 42 , and the touch driving electrode blocks except the touch driving electrode blocks in the Nth matrix row are all the first driving electrode blocks 41 .

In this embodiment, the first substrate 1 may specifically include M first touch driving signal transmission lines 5 and one second touch driving signal transmission line 6 . Wherein, the M first touch driving signal transmission lines are respectively connected to the first touch driving electrode blocks 41 in the M matrix columns, and the second touch driving signal transmission lines are connected to the second touch driving electrode blocks 41 in all the M matrix columns. The control drive electrode block 42 is connected.

For example, as shown in FIG. 7, the first one of the first touch driving signal transmission lines 5, namely TX1, is connected to the first touch driving electrode block 41 in the first matrix column, and the first touch driving signal transmission line 5 The second line, TX2, is connected to the first touch drive electrode block 41 in the second matrix column, and so on until the Mth first touch drive signal transmission line 5 is connected to the first touch drive electrode block 41 in the Mth matrix column. The drive electrode block 41 is connected. The second touch driving signal transmission line 6 (TX-add) is connected to the second touch driving electrode blocks 42 in all the M columns of the matrix.

Then, as shown in FIG. 8 , within a display period (for example, a frame time), when the gate line corresponding to the first matrix row is in an open state (that is, the gate line 9 transmits a gate drive signal, the first matrix row is located The pixel row at the position is in the display driving state display), and the first touch driving signal is input to TX1 which is not connected to the second touch driving electrode block 42 located in the first matrix row in the first matrix column, and the first touch driving signal is input by TX1 The touch driving signal is transmitted to the first touch driving electrode block 41 in the first matrix column to realize the touch detection of the corresponding touch area at the position of the first touch driving electrode block 41 in the first matrix column;

Since the grid lines are usually scanned row by row, after the grid lines corresponding to the first matrix row are scanned, the grid lines corresponding to the second matrix row will be scanned, then, the grid lines corresponding to the second matrix row In the ON state, the first touch driving signal is input to TX2 which is not connected to the second touch driving electrode block 42 in the second matrix row in the second matrix column, and TX2 transmits the first touch driving signal to the second touch driving electrode block 42. In the first touch driving electrode block 41 in the second matrix column, the touch detection of the corresponding touch area at the position of the first touch driving electrode block 41 in the second matrix column is realized;

Followed by analogy, until the gate line at the position of the Nth matrix row is in the open state, the first touch driving signal is input to the TX(M), and the TX(M) transmits the first touch driving signal to the Mth In the first touch driving electrode block 41 in the matrix column, the touch detection corresponding to the position of the first touch driving electrode block 41 in the Mth matrix column is realized, so that within a display period, all matrix columns The touch detection of the corresponding touch area where the first touch driving electrode block 41 is located.

Then, between two adjacent display periods, input the second touch driving signal to TX-add, and transmit the second touch driving signal to the second touch driving electrodes in all M columns of matrix columns by TX-add Block 42, so as to realize the touch detection of the corresponding touch area where the second touch drive electrode block 42 in all M columns of matrix columns is located.

In subsequent display cycles and adjacent display cycles, the above-mentioned process is repeatedly performed to realize synchronous execution of display driving and touch detection.

It can be seen from the above description that the touch display device according to the embodiment of the present invention adopts column-by-column scanning for touch detection, which is completely different from the conventional progressive scanning commonly used.

Although in the above embodiment, the second touch driving electrode block 42 includes one touch driving electrode block and the first touch driving electrode block 41 includes a plurality of touch driving electrode blocks for illustration, in other embodiments, The second touch driving electrode block 42 may also include a plurality of touch driving electrode blocks 4 in a matrix column, and is connected to at least one second touch driving signal transmission line.

In the above-mentioned embodiment, the matrix row of the first touch driving electrode block 41 receiving the first touch driving signal is adjacent to the matrix row of the second touch driving electrode block 42 corresponding to the gate line 9 in the on state. However, in other embodiments, the row of the matrix where the first touch driving electrode block 41 receiving the first touch driving signal is located, and the second touch driving electrode block 42 corresponding to the gate line 9 that is currently in the on state are located Matrix rows, separated by a preset matrix row distance.

For example, also in the structure shown in FIG. 7 , in the first matrix column, the touch driving electrode block located in the first matrix row is the second touch driving electrode block 42, and the touch driving electrode block located in the second matrix row The electrode block can be the second touch driving electrode block 42, or a separate touch driving electrode block (that is, neither the second touch driving electrode block 42 nor the first touch driving electrode block 41) , the touch drive electrode block can be connected to the second touch drive signal transmission line 6 (or connected to other signal lines, and can also be suspended in extreme cases), and the touch drive electrode block located in the third matrix row is the first touch drive electrode block. The driving electrode block 41 is controlled.

When the gate lines 9 corresponding to the touch driving electrode blocks located in the first matrix row are in the open state, the gate lines 9 corresponding to the touch driving electrode blocks located in the second matrix row may be in the closed state, but the gate lines 9 located in the second matrix row The touch driving electrode block does not receive the first touch driving signal, and at this time, the touch driving electrode block located in the third matrix row receives the first touch driving signal, so it can be seen that the touch driving electrode block receiving the first touch driving signal The matrix row where the first touch driving electrode block 41 is located and the matrix row where the second touch driving electrode block 42 is located corresponding to the gate line 9 that is currently in the on state are separated by a distance of one matrix row, thereby avoiding display driving and touch control. There is mutual interference and influence between control and detection.

The first touch driving signal and the second touch driving signal involved in the above-mentioned embodiments of the present invention may be the same touch driving signal, and the first substrate involved in the above-mentioned embodiments of the present invention may specifically be an array substrate, Specifically, the second substrate may be a color filter substrate.

The embodiment of the present invention also provides a method for driving a touch display device, which is used to drive the touch display device provided by the above embodiment of the present invention;

As shown in Figure 9, the method may specifically include:

Step 91, within a display time period, input the first touch driving signal to the first touch driving signal transmission line 5 connected to the first touch driving electrode block 41 in the first matrix column, wherein the first touch driving signal is received The gate line 9 corresponding to the first touch drive electrode block 41 of the control drive signal is in the off state, and when the gate line 9 corresponding to the first touch drive electrode block 41 in the first matrix column is in the off state, the first The gate line 9 corresponding to the second touch driving electrode block 42 in the matrix column is in an open state;

Step 92, within the display time period, sequentially input the first touch driving signal to the first touch driving signal transmission line 5 connected to the first touch driving electrode block 41 in other matrix columns according to a preset sequence;

Step 93 , inputting a second touch driving signal to the second touch driving signal transmission line 6 between the display time period and the next display time period.

It can be seen from the above that the touch display device provided by the embodiment of the present invention sequentially transmits the first touch driving signal to the first touch driving electrode block in the corresponding matrix column within a display time period; wherein , the gate line corresponding to the first touch drive electrode block receiving the first touch drive signal is in the off state, and when the gate line corresponding to the first touch drive electrode block in a matrix column is in the off state, the matrix The gate line corresponding to the second touch driving electrode block in the column is in an open state; and the second touch driving signal is transmitted to the second touch driving electrode block between adjacent display time periods. Therefore, by synchronizing the display drive and touch detection, the touch detection time is prolonged, the transmission frequency of the touch detection signal is reduced, the noise of the touch display device is reduced, and the display performance of the touch display device is improved. quality.

The above are only embodiments of the utility model, and it should be pointed out that for those of ordinary skill in the art, some improvements and modifications can also be made without departing from the principle of the utility model. It should be regarded as the protection scope of the present utility model.
