Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Currently, in order to realize the infrared detection function of the display screen, an infrared light source is usually arranged on one side of the photosensitive detection area of the display screen. When a touch object approaches the infrared photosensitive area, infrared light emitted by the infrared light source is reflected by the touch object and then received by the infrared photosensitive unit of the photosensitive detection area, so that the infrared photosensitive unit generates a corresponding infrared detection signal.
However, since the infrared light source is disposed on one side of the photosensitive detection region, the infrared light sensed by the infrared sensing unit close to the infrared light source is stronger, and the infrared light sensed by the infrared sensing unit far away from the infrared light source is weaker, so that the infrared detection signal generated by the infrared sensing unit far away from the infrared light source is easily ignored, thereby affecting the accuracy and sensitivity of the infrared detection.
In order to solve the above technical problem, an embodiment of the present invention provides a display screen, where the display screen includes a display panel and an infrared light source; the display panel comprises a display area; the display area is provided with a plurality of sub-pixels arranged in an array; at least part of the display area is a photosensitive detection area; infrared photosensitive units are arranged in gaps of at least part of sub-pixels in the photosensitive detection area; the infrared light source comprises a plurality of infrared light-emitting elements; the orthographic projection of the infrared light-emitting elements on the plane of the display area is distributed on at least two opposite sides of the photosensitive detection area; or the orthographic projection of the plurality of infrared light-emitting elements on the plane of the display area is positioned in the photosensitive detection area.
By adopting the technical scheme, on the first hand, the infrared photosensitive unit is arranged in the gap of the sub-pixels of the photosensitive detection area, so that the display function of the sub-pixels of the display area is not influenced on the premise that the infrared detection function can be realized, the display screen has higher screen occupation ratio, and the display effect of the display screen is favorably improved; in a second aspect, infrared light emitted by an infrared light source in a display screen can be received by an infrared light sensing unit arranged in the display panel after being reflected and/or scattered by a touch body on the display surface side of the display panel, so as to generate a corresponding infrared detection signal, so as to realize functions of space touch, fingerprint identification or virtual key and the like, thereby enriching the functions of the display screen; the third aspect, through making infrared light source middle infrared light emitting component be located the at least relative both sides of sensitization detection zone or be located the sensitization detection zone in the planar orthographic projection of sensitization detection zone place, make the infrared light of infrared light source middle infrared light emitting component transmission cover whole infrared sensitization detection zone uniformly, in order to prevent to set up in one side of infrared sensitization detection zone because of infrared light source, make the intensity of the infrared light that infrared light source's infrared sensitization unit can be detected of keeping away from weak and neglected easily, influence the phenomenon production of infrared detection degree of accuracy, thereby when adopting infrared light source and infrared sensitization unit to realize space touch-control, fingerprint identification or functions such as virtual button, be favorable to improving infrared detection's degree of accuracy and sensitivity.
The above is the core idea of the present invention, and based on the embodiments of the present invention, a person skilled in the art can obtain all other embodiments without creative efforts, which belong to the protection scope of the present invention. The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
It should be noted that, in the embodiment of the present invention, at least a part of the display area of the display screen is the photosensitive detection area, that is, all the display areas of the display screen are the photosensitive detection areas, so as to implement a full-screen fingerprint identification or spatial touch function, or a part of the display areas of the display screen are the photosensitive detection areas, so as to implement a fingerprint identification or virtual key function in a specific area, which is not specifically limited in this embodiment of the present invention.
In the embodiment of the invention, the orthographic projections of a plurality of infrared light-emitting elements of an infrared light source in a display screen on the plane of a photosensitive detection area can be distributed on at least two opposite sides of the photosensitive detection area, namely the plurality of infrared light-emitting elements of the infrared light source are arranged oppositely; or the orthographic projection of a plurality of infrared light-emitting elements of the infrared light source in the display screen on the plane of the photosensitive detection area is positioned in the photosensitive detection area. The following describes an exemplary embodiment of the present invention with reference to the above two setting modes and the accompanying drawings.
When the orthographic projection of a plurality of infrared light emitting elements of the infrared light source in the display screen on the plane of the photosensitive detection area is distributed on at least two opposite sides of the photosensitive detection area, the plurality of infrared light emitting elements of the infrared light source are oppositely arranged, and the orthographic projection of the plane of the photosensitive detection area can be distributed on two sides, four sides, … and N sides of the photosensitive detection area, wherein N is an even number.
Fig. 1 is a schematic top view of a display screen according to an embodiment of the present invention. As shown in fig. 1, the display device 100 includes a display panel 10 and infrared light sources (21 and 22), and a display area 101 of the display panel is provided with a plurality of sub-pixels 110 arranged in an array. Set up infrared sensitization unit 120 through the clearance at least partial sub-pixel 110, promptly through setting up infrared sensitization unit 120 at non-open area to under the prerequisite that does not influence sub-pixel 110 of display screen 100 and show, can realize infrared detection function, make the display screen have higher screen and account for the ratio, thereby be favorable to improving the display effect of display screen.
The infrared light source (21 and 22) of the display screen 100 includes a plurality of infrared light emitting elements 210, and orthographic projections of the plurality of infrared light emitting elements 210 on a plane where the display area 101 of the display panel 10 is located are located on two opposite sides of the photosensitive detection area 1011. For example, the infrared light source may include a plurality of infrared light source groups, and each infrared light source group may include at least one infrared light emitting element 210. When the photosensitive detection area 1011 includes the first side 1010 and the second side 1020 which are opposite to each other, and includes the third side 1030 and the fourth side 1040 which are opposite to each other, the infrared light source may include the first infrared light source group 21 and the second infrared light source group 22, and the first infrared light source group 21 and the second infrared light source group 22 are disposed opposite to each other, at this time, the orthographic projection of the first infrared light source group 21 on the plane of the photosensitive detection area 1011 and the orthographic projection of the second infrared light source group 22 on the plane of the photosensitive detection area 1011 are located on the first side 1010 and the second side 1020 of the photosensitive detection area 1011, respectively. At this time, the infrared light emitted by each infrared light emitting element 210 in the infrared light source will be emitted through the display panel, and when a touch object is located on the display surface side of the display panel, the infrared light will be reflected and/or scattered on the touch object; the infrared sensing unit 120 can receive the infrared light reflected and/or scattered by the touch object and generate a corresponding infrared detection signal, so that the display screen 100 can implement functions of corresponding space touch, fingerprint identification or virtual key, etc.
Illustratively, when all the display areas 101 of the display screen 100 are the photosensitive detection areas 1011, the infrared light sources (21 and 22) cooperate with the infrared photosensitive units 120 to enable the display screen 100 to realize the space touch function. Because the orthographic projections of the first infrared light source group 21 and the second infrared light source group 22 of the infrared light sources on the plane of the photosensitive detection area 1011 are respectively positioned on the first side 1010 and the second side 1020 of the photosensitive detection area 1011, when no touch object exists on the display surface side of the display panel, the intensity of the infrared light covered by the area where the infrared photosensitive unit 120 close to the edge of the first side 1010 of the photosensitive detection area 1011 is positioned is consistent with the intensity of the infrared light covered by the area where the infrared photosensitive unit close to the edge of the second side 1020 of the photosensitive detection area 1011 is positioned; when a touch object is located on the display surface side of the display panel 10, the touch object may be a limb (finger, palm, etc.) of a user, and is close to the photosensitive detection area 1011 of the display panel 10, for example, when a vertical distance between the touch object and the photosensitive detection area 1011 is within a preset range and/or a horizontal distance is within a preset range, the infrared light emitted by the infrared light emitting element 210 can be reflected by the touch object, so that the infrared photosensitive unit 120 of the photosensitive detection area 1011 can be activated, and collect the infrared light reflected by the touch object, and generate a corresponding infrared detection signal.
When the touch object moves along the Y direction, the infrared light reflected by the touch object received by the photo sensor units 120 close to the third side 1030 of the photo sensor detection area 1011 gradually decreases, and the infrared light reflected by the touch object received by the photo sensor units 120 close to the fourth side 1040 of the photo sensor detection area 1011 gradually increases, so that the infrared light sensor units 120 close to the third side 1030 of the photo sensor detection area 1011 generate corresponding infrared detection signals, and the change trend of the infrared light sensor units 120 close to the fourth side 1040 of the photo sensor detection area 1011 generate corresponding infrared detection signals is opposite, thereby knowing the moving direction of the touch object, realizing corresponding touch functions according to the moving direction of the touch object, and displaying sliding, page turning and the like of a screen, thereby realizing corresponding touch based on the spatial motion of the touch object, namely, realizing non-contact touch of a gesture space.
When the touch object moves along the X direction, the moving direction of the touch object can be known through the variation trend of the infrared detection signal of the infrared photosensitive unit 120 near the first side 1010 of the photosensitive detection area 1011 and the variation trend of the infrared detection signal of the infrared photosensitive unit 120 near the second side 1020 of the photosensitive detection area 1011, and the corresponding touch control can be realized based on the spatial motion of the touch object, that is, the non-contact touch control of the spatial gesture.
When a touch object floats above the photosensitive detection area 1011 or touches a certain position of the display screen 100, the infrared light sensing units 120 of the touch object in and/or near the coverage area of the orthographic projection of the plane of the photosensitive detection area receive the infrared light reflected by the touch object and generate corresponding infrared detection signals, and the orthographic projection of the touch object on the plane of the photosensitive detection area 1011 on the photosensitive detection area 1011 can be determined based on the infrared detection signals of the infrared light sensing units 120. For example, when it is known that the touch object is suspended above an application icon in the photosensitive detection area 1011 through the infrared detection signal of each infrared photosensitive unit 120, the application software corresponding to the application icon may be controlled to be started, so that the current display screen of the display panel is switched to the start interface of the application software, thereby implementing the non-contact click touch function. Accordingly, when the touch object is a finger of a user and is suspended above the photosensitive detection area 1011 or touches a certain position of the display screen 100, the infrared detection signal of the infrared photosensitive unit 120 at the position can be used to obtain a fingerprint image of the user, thereby implementing a fingerprint identification function.
In the embodiment of the present invention, since the projections of the infrared light emitting elements 210 of the infrared light source on the plane of the photosensitive detection area 1011 are distributed on the first side 1010 and the second side 1020 opposite to the photosensitive detection area 1011, the intensity of the infrared light emitted by the infrared light emitting elements 210 in the infrared light source in the area where the infrared photosensitive units 120 close to the first side 1010 of the photosensitive detection area 1011 are located is consistent with the intensity of the area where the infrared photosensitive units 120 close to the second side 1020 of the photosensitive detection area 1011 are located, so as to prevent the infrared detection signals generated by the infrared photosensitive units 120 at the positions where the intensity of the infrared light is weaker from being ignored due to different intensities of the infrared light at the respective positions, and thus when the functions such as spatial touch, fingerprint identification, or virtual key are implemented by using the infrared light source and the infrared photosensitive units, the accuracy and sensitivity.
It should be noted that, in the embodiment of the present invention, the infrared photosensitive units are disposed in gaps between at least some sub-pixels of the photosensitive detection area, that is, the infrared photosensitive units may be disposed in one-to-one correspondence with the sub-pixels, or one infrared photosensitive unit may correspond to multiple sub-pixels, which is not specifically limited in this embodiment of the present invention.
In the display panel shown in fig. 1, all display areas of the display panel are multiplexed as photosensitive detection areas, in the embodiment of the present invention, a part of the display areas of the display panel are photosensitive detection areas, and the infrared photosensitive units 120 are only disposed in the sub-pixel gaps of the photosensitive detection areas, while the infrared photosensitive units are not disposed in other display areas.
For example, fig. 2 is a schematic top view structure diagram of another display screen provided in an embodiment of the present invention. Fig. 2 is the same as fig. 1, reference is made to the above description of fig. 1, and only the differences between fig. 2 and fig. 1 will be exemplarily described. As shown in fig. 2, a portion of the display area 101 of the display panel 10 in the display screen 100 is a photosensitive detection area 1011, an infrared photosensitive unit 120 is disposed between sub-pixels 110 of the photosensitive detection area 1011, and a projection of the infrared photosensitive element 210 of the infrared light source (21 and 22) on a plane where the photosensitive detection area 1011 is located may also be located on two opposite sides of the photosensitive detection area 1011, so that the infrared photosensitive unit 120 in the photosensitive detection area 1011 can receive infrared light reflected by a touch object and generate a corresponding infrared detection signal. At this time, when a touch object such as a finger contacts the photosensitive detection area 1011, infrared light emitted from the infrared light emitting element 210 in the infrared light sources (21 and 22) can be reflected by the touch object, and the infrared light reflected by the touch object is received by the infrared sensing unit 120 in the photosensitive detection area 1011, so that the infrared sensing unit 120 is activated and generates a corresponding infrared detection signal, so that the motion of the touch object can be determined according to the infrared detection signal generated by the infrared sensing unit 120, and a function corresponding to the motion of the touch object can be executed. For example, when the photosensitive detection area 1011 is a virtual key for returning to a main menu, when a touch object such as a finger contacts the infrared photosensitive unit 120 of the photosensitive detection area 1011, infrared light emitted by the infrared light source is reflected by the touch object and received by the infrared photosensitive unit 120 of the photosensitive detection area 1011, and the infrared photosensitive unit 120 can generate a corresponding infrared detection signal according to the received infrared light; at this time, the infrared detection signal generated by the infrared sensing unit 120 in the sensing detection area 1011 can indicate that a touch object touches the virtual key, and the display screen switches the current display frame to the display frame of the main menu. Therefore, the corresponding key function can be realized without arranging mechanical keys in the display screen, and the display screen is ensured to have higher screen occupation ratio.
Meanwhile, when the display screen is provided with the mechanical key, the mechanical key can generate a corresponding signal when being pressed by pressing force, so that the display screen can realize corresponding functions, and the mechanical key can be damaged or deformed due to long-term concentrated stress, and the display is influenced. According to the embodiment of the invention, the infrared photosensitive unit of the photosensitive detection area is adopted to realize the function of the key, and a user only needs to lightly touch, click or suspend above the photosensitive detection area, so that the phenomenon that the display screen deforms due to concentrated stress can be prevented, the service life of the display screen can be prolonged, and the cost of the display screen can be reduced. Correspondingly, when the photosensitive detection area 1011 is a virtual key, the virtual key may also be a virtual key for increasing/decreasing volume, returning to a previous page, entering a next page, and the like, which is not specifically limited in the embodiment of the present invention.
In addition, as shown in fig. 3, when the display screen 100 is a foldable display screen or a curved display screen, the photosensitive detection area 1011 may be located in a side display area of the display screen, so as to enable the side of the display screen to display a picture and conform to the current habit of using keys.
In the above description, the orthographic projections of the infrared light emitting elements of the infrared light source on the plane of the photosensitive detection area are exemplarily described as being located on two opposite sides of the photosensitive detection area, and in the following description, the orthographic projections of the infrared light emitting elements of the infrared light source on the plane of the photosensitive detection area are exemplarily described as being located on four opposite sides of each two of the photosensitive detection areas.

At this time, the orthographic projection of the infrared light emitting element 210 of the infrared light source 20 on the plane of the photosensitive detection area 1011 is uniformly distributed in the photosensitive detection area 1011, so that after the infrared light emitted by the infrared light emitting element 210 is reflected by the touch object, the infrared light can be received by the infrared photosensitive unit in the photosensitive detection area 1011, and a corresponding infrared detection signal is generated, thereby corresponding operation can be executed according to the infrared detection signal. Meanwhile, because the orthographic projection of the infrared light emitting elements 210 of the infrared light source 20 on the plane of the photosensitive detection area 1011 is uniformly distributed in the photosensitive detection area 1011, the intensity of infrared light emitted by the infrared light emitting elements 210 and received by the infrared photosensitive units at all positions of the photosensitive detection area 1011 is kept consistent, so that the infrared detection signals generated by the infrared photosensitive units at positions with weaker infrared light intensity are ignored due to different infrared light intensities at all positions, and the accuracy and sensitivity of detection can be improved when the functions of space touch control, fingerprint identification or virtual key pressing and the like are realized by adopting the infrared light source and the infrared photosensitive units.
It should be noted that the display panel in the display screen provided in the embodiment of the present invention may be an organic light emitting display panel or a liquid crystal display panel, and the embodiment of the present invention is not particularly limited thereto. When the display panel of the display screen is a liquid crystal display panel, a backlight module is also arranged in the display screen and can provide a light source for the display panel. At the moment, the infrared light source can be arranged in the backlight module to adopt the existing structure in the backlight module to support and fix the infrared light source, and a supporting and fixing structure is not required to be additionally arranged for the infrared light source, so that the structure of the display screen can be simplified, the cost of the display screen is reduced, and the screen occupation ratio of the display screen is improved.

As shown in fig. 7, the display screen 100 includes a display panel 10, an infrared light source and a backlight module 30. The backlight module 30 at least comprises a module frame 31, an optical film 33 and a display light source 32 positioned at the side of the optical film 33; the optical film 33 may include a light guide plate, a diffusion sheet, a reflection sheet, and the like, and the display light source 32 enters through the light incident surface of the light guide plate, is homogenized by the light guide plate, reaches the display panel 10 through the synergistic effect of other optical films, and exits through the display surface of the display panel 10, so that the display screen 100 can emit light. At this time, the infrared light emitting elements 210 of the infrared light source are disposed on two opposite sides of the module frame 31, so that the orthographic projection of the infrared light emitting elements 210 of the infrared light source on the plane of the photosensitive detection area 1011 is located on two opposite sides of the photosensitive detection area 1011, thereby facilitating the improvement of the accuracy and sensitivity of the infrared detection.
Fig. 8 is a schematic diagram illustrating a film structure of another display screen according to an embodiment of the present invention. The same in fig. 8 as in fig. 7 can be referred to the above description of fig. 7, and only the differences in fig. 8 from fig. 7 will be exemplarily described here. As shown in fig. 8, the backlight module 30 is provided with a direct-type display light source 32, i.e. the display light source is located on a side of the optical film 33 away from the display panel 10. In this case, similarly, the light emitted from the display light source 32 is optically processed by the optical film 33, reaches the display panel 10, and is emitted through the display surface of the display panel 10, so that the display panel 100 can emit light for display. Correspondingly, the infrared light emitting elements 210 of the infrared light source can also be disposed on two opposite sides of the module frame 313 in the backlight module 30, so that the orthographic projection of the infrared light emitting elements 210 of the infrared light source on the plane of the photosensitive detection area 1011 is located on two opposite sides of the photosensitive detection area 1011, thereby facilitating the improvement of the accuracy and sensitivity of the infrared detection.

At this time, the backlight module may be a backlight module of a direct type light source.
Exemplarily, fig. 9 is a schematic top view of a lamp panel according to an embodiment of the present invention. As shown in fig. 9, the lamp panel 321 is provided with a light emitting diode 322 and an infrared light emitting element 210. The light emitted by the light emitting diodes 322 can pass through the display panel, so that the display screen can emit light; the infrared light emitted from the infrared light emitting element 210 can be reflected by a touch object on the display surface side of the display panel after passing through the display panel, and received by the infrared light receiving unit, thereby implementing an infrared detection function. Meanwhile, because the light emitting diodes 322 and the infrared light emitting elements 210 arranged in the lamp panel 321 are arranged in an array, when the sizes of the infrared light emitting elements 210 and the light emitting diodes 322 are the same, the infrared light emitting elements 210 may be arranged at positions originally used for arranging the light emitting diodes 322 on the premise of not affecting the display function of the display screen 100, so that the light emitting diodes 322 and the infrared light emitting elements 210 can be controlled to emit light at the same time. Like this, need not additionally to set up the structure of fixed infrared light emitting component 210 equally to can simplify the structure of display screen, reduce the cost of display screen, make the display screen have higher screen to account for than.
Optionally, fig. 10 is a schematic view of a film structure of another display screen provided in an embodiment of the present invention. As shown in fig. 10, when the infrared light emitting elements 21 of the infrared light source can be disposed in the lamp panel 321, the orthographic projection of the infrared light emitting elements 210 on the display panel 10 and the infrared sensing unit 120 do not overlap each other. In this way, the infrared sensing unit 120 can be prevented from blocking the infrared light emitted by the infrared light emitting element 210, so as to ensure that the infrared light emitted by the infrared light emitting element 210 can be emitted through the display panel, and can be reflected by a touch object when the touch object exists and then received by the infrared sensing unit 120, thereby realizing a corresponding infrared detection function.
Although the orthographic projection of the infrared light emitting element 210 on the display panel 10 does not overlap with the infrared light sensing unit 120, in order to enable the infrared light received by the infrared light sensing unit 120 to have a sufficiently large light intensity, the orthographic projection of the infrared light emitting element 210 on the display panel 10 needs to be as close as possible to the infrared light sensing unit 120, for example, the orthographic projection of the infrared light emitting element 210 on the display panel 10 may be spaced from the infrared light sensing unit 120 by 2 to 3 sub-pixels. On the premise of realizing the infrared detection function, the embodiment of the invention does not specifically limit the distance between the orthographic projection of the infrared light-emitting element on the display panel and the infrared photosensitive unit.
Optionally, fig. 11 is a schematic top view structure diagram of another display screen provided in an embodiment of the present invention. As shown in fig. 11, a plurality of infrared scanning signal lines 130 and a plurality of infrared signal reading lines 140 are disposed in a display area 101 of a display panel 10 in a display screen 100. Wherein, the infrared light sensing units 120 located in the same row are electrically connected to the same infrared scanning signal line 130; the infrared sensing units 120 are electrically connected to the infrared signal reading lines 140 in a one-to-one correspondence.
Specifically, the infrared scanning signal transmitted by each infrared scanning signal line 130 can control the infrared light sensing units 120 in each row to start and generate a corresponding infrared detection signal, and the corresponding infrared detection signal is output by each infrared signal reading line 140. When the infrared light sensing units 120 are used to implement a contactless touch function, since the infrared detection signals output by the infrared light sensing units 120 at various positions need to be obtained at the same time to obtain the moving direction of the touch object, each infrared light sensing unit 120 needs to output a corresponding infrared detection signal through a separate infrared signal reading line, thereby implementing a dynamic contactless touch function.
Optionally, fig. 12 is a schematic view of a film structure of a display panel according to an embodiment of the present invention. As shown in fig. 12, the infrared sensing unit 120 in the display panel includes an infrared sensing element 122 and an infrared detection circuit 121, and the infrared sensing element 122 is electrically connected to the infrared detection circuit 121, so that the infrared sensing element 122 receives corresponding infrared light, converts the received infrared light into an electrical signal, and converts the electrical signal into a corresponding infrared detection signal through the infrared detection circuit 121. At this time, the infrared detection circuit 121 may include at least one first thin film transistor, and the sub-pixel 110 may include at least one second thin film transistor 111. The first thin film transistor and the second thin film transistor 111 can be formed by using the same material and using the same process, so that the manufacturing process of the display panel can be simplified, the manufacturing cost of the display panel can be reduced, and the display panel can be thinned.
In addition, when the display panel is a liquid crystal display panel, the display panel may further include a pixel electrode 112, a common electrode 113, a liquid crystal layer, and a color film substrate 150. The pixel electrode 112 may be electrically connected to the second thin film transistor 111 to receive a corresponding display signal when the second thin film transistor 111 is turned on, so that the pixel electrode 112 and the common electrode 113 can form an electric field to drive the liquid crystal molecules 160 of the liquid crystal layer to twist, and light can pass through the color filter substrate 150 to display a colorful picture. Correspondingly, the infrared sensing element 122 may include at least one first electrode, and the first electrode may be disposed on the same layer as the common electrode 113, so as to further simplify the manufacturing process of the display panel, reduce the manufacturing cost of the display panel, and facilitate the thinning of the display panel.
For example, fig. 13 is a circuit structure diagram of an infrared sensing unit according to an embodiment of the present invention. As shown in fig. 13, the infrared light sensing unit includes an infrared light sensing element 122 and an infrared detection circuit 121; the infrared sensing element 122 can be, for example, an infrared photodiode, one end of the infrared sensing element 122 is Grounded (GND), and the other end is electrically connected to the infrared detection circuit 121; the infrared detection circuit 121 includes a drive transistor M1, a reset transistor M2, and a storage capacitor C1. The reset transistor M2 can be turned on or off under the control of a reset signal received by its gate, and when it is turned on, will transmit the power signal VDD to the gate of the driving transistor M1 to reset the driving transistor M1; when the infrared photosensitive element 122 receives the infrared light, the infrared photosensitive element 122 can generate a corresponding electrical signal, and the electrical signal is transmitted to the gate of the driving transistor M1, so that the driving transistor M1 outputs a corresponding infrared detection signal Vout according to the electrical signal of the gate, thereby implementing the infrared detection function.
It should be noted that fig. 13 is only an exemplary diagram of an embodiment of the present invention, and a specific structure of the infrared photosensitive unit is not limited in the embodiment of the present invention on the premise that the infrared photosensitive unit can realize an infrared detection function.
Based on the same inventive concept, the embodiment of the invention also provides a control method of the display screen, which is used for controlling the display screen provided by the embodiment of the invention, so that the display screen can realize the functions of space touch, fingerprint identification or virtual keys and the like. The control method of the display screen is executed by the control device of the display screen provided by the embodiment of the invention, and the control device of the display screen can be realized in a software and/or hardware mode. Fig. 14 is a flowchart of a control method of a display screen according to an embodiment of the present invention. As shown in fig. 14, the fingerprint identification method includes:
s110, acquiring an infrared detection signal generated by the infrared sensing unit according to infrared detection light in real time; the infrared detection light is infrared light which is emitted by an infrared light source and returns to the infrared photosensitive unit through the display surface of the display panel;
and S120, determining the user gesture on the display surface side of the display panel according to the infrared detection signal, and executing a gesture action to control the display screen to enter an application picture or switch the application picture.
Therefore, the infrared light source in the display screen can emit infrared light, and when the infrared light source meets a touch object, the infrared light is reflected by the touch object, and the reflected light is the infrared detection light. The infrared light sensing unit arranged in the display screen can receive the infrared detection light and generate a corresponding infrared detection signal; the action of the touch object, namely the gesture of the user, can be known through the infrared detection signal generated by the infrared photosensitive unit. The user gesture may include at least one of a unidirectional horizontal movement, a unidirectional vertical movement, a floating still, a tap click, a reciprocating shift, a swing movement, and a bidirectional movement, so that an action corresponding to the user gesture, such as entering an application screen, switching the application screen, moving an icon, and the like, can be performed according to the user gesture.
Optionally, the method for determining the user gesture may be: determining the variable quantity of the infrared detection signals of the infrared photosensitive units at each position according to the infrared detection signals; and determining the moving direction of the user gesture according to the variable quantity of the infrared detection signals of the infrared light sensing units at the positions. Fig. 15 is a flowchart of a method for determining a user gesture according to an embodiment of the present invention. As shown in fig. 15, the method of determining a user gesture includes:
s1211, determining the variable quantity of the infrared detection signals of the infrared light sensing units at each position according to the infrared detection signals;
and S1212, determining the moving direction of the user gesture according to the variable quantity of the infrared detection signal of the infrared photosensitive unit at each position.
Illustratively, when the user gesture is unidirectional horizontal movement, the infrared detection signals generated by the infrared light sensing units in the movement direction of the user gesture are enhanced and then weakened, and thus the user gesture can be known through the variation of the infrared detection signals generated by the infrared light sensing units. When the user gesture is in other situations, the user gesture can also be known according to the variation of the infrared detection signal generated by each infrared photosensitive unit, and the technical principle of the method can refer to the above description about the detection of the touch object or the user gesture, and is not described herein again.
Optionally, the method for determining the user gesture may further include: determining the number of first infrared detection signals generated by each infrared photosensitive unit within preset time according to the infrared detection signals; and judging whether the number of the first infrared detection signals is greater than or equal to the preset number of infrared photosensitive units, and determining the position of the user gesture according to the position of the first infrared photosensitive units when the number of the first infrared detection signals is greater than or equal to the preset number of infrared photosensitive units. Fig. 16 is a flowchart of another method for determining a user gesture according to an embodiment of the present invention. As shown in fig. 16, the method for determining a user gesture specifically includes:
s1221, determining the number of first infrared detection signals generated by each infrared photosensitive unit in preset time according to the infrared detection signals;
s1222, judging whether the number of the first infrared detection signals is larger than or equal to the preset number of the infrared photosensitive units; if yes, go to S1223;
and S1223, determining the position of the user gesture according to the position of the first infrared photosensitive unit.
For example, when the user wants to open the application software in the display screen, the user gesture may be hovering, i.e., the touch object is stationary above the icon of the application software. At this time, if a touch object is displayed in the infrared detection signal of the infrared photosensitive unit, the infrared detection signal generated by the infrared photosensitive unit may be greater than or equal to a preset infrared detection signal, and the infrared detection signal generated by the infrared photosensitive unit may be determined as the first infrared detection signal. When the touch object is still above the icon of the application software, the infrared detection signal generated by the infrared light sensing unit at the position of the application icon is greater than or equal to the preset infrared detection signal, that is, the infrared detection signal generated by the infrared light sensing unit at the position of the application icon is the first infrared detection signal, and the infrared light sensing unit at the position continuously generates the first infrared detection signal because the touch object is still above the icon of the application software, and the infrared light sensing unit can generate the first infrared detection signal in each frame of infrared detection process. Therefore, whether the gesture of the user is in the suspension static state or not can be known by detecting the number of the first infrared detection signals generated by the infrared photosensitive unit. For example, when the number of the first infrared detection signals exceeds a preset number, the gesture of the user is considered to be in a floating static state, and application software in the display screen can be controlled to be started and switched to a picture corresponding to the application software; and when the number of the first infrared detection signals does not exceed the preset number, the gesture of the user is considered to cause the icon passing through the application software to execute actions such as screen sliding and the like.
According to the embodiment of the invention, infrared light emitted by the infrared light source in the display screen is reflected and/or scattered by the touch body on the display surface side of the display panel, and then is received by the infrared photosensitive unit arranged in the display panel to generate a corresponding infrared detection signal, so that the functions of space touch, fingerprint identification or virtual key and the like are realized, and the functions of the display screen can be enriched.
