[0044] Please see Figures 1 to 12 This application provides a display panel, which includes a substrate 1, a display module 2, a light-sensing module 3, and a touch module 4, all of which are disposed on the substrate 1. The display module 2 includes an array of pixel units 21, with multiple pixel units 21 arranged in a row along a first direction and in a column along a second direction. The pixel units 21 can be pixels of different colors arranged sequentially, such as... Figure 2As shown, pixel unit 21 includes a first pixel unit 211, a second pixel unit 212, and a third pixel unit 213. The first pixel unit 211 corresponds to red pixels, the second pixel unit 212 corresponds to green pixels, and the third pixel unit 213 corresponds to blue pixels. Each column consists of pixels of the same color. Adjacent first pixel units 211, second pixel units 212, and third pixel units 213 are arranged in a row as the smallest repeating units extending along the first direction. It should be noted that... Figure 2 This is merely an example to facilitate understanding of one arrangement of display module 2, and should not be construed as being limited to this.

[0045] The light-sensing module 3 includes multiple light-sensing units 31 and multiple data lines. The multiple light-sensing units 31 are arrayed among the pixel units 21. The light-sensing units 31 and pixel units 21 can be in a one-to-one correspondence, or one light-sensing unit 31 can correspond to multiple rows of pixel units 21, such as... Figure 2 As shown, one photosensitive unit 31 corresponds to four rows of pixel units 21. Furthermore, the distribution spacing of the photosensitive units 31 can be multiple columns or rows of pixel units 21, such as... Figure 2 As shown, pixel unit 21 includes three colors: red, green, and blue. The distribution interval of light-sensing units 31 when arranged in rows is 3 columns of pixel units 21. Multiple data lines are electrically connected to light-sensing units 31 in the same column and / or row, respectively. The data lines are used to provide constant voltage DC signals to light-sensing units 31 and to transmit sensing signals.

[0046] The touch module 4 includes multiple first antennas 41 and multiple second antennas 42. The first antennas 41 extend along a first direction, and the second antennas 42 extend along a second direction. The multiple first antennas 41 form multiple first antenna loops 411, and the multiple second antennas 42 form multiple second antenna loops 421. Figure 3 and Figure 4 The image only identifies one antenna loop formed by connecting two adjacent antennas; in reality, every pair of adjacent antennas forms a loop. It should be noted that... Figure 3 and Figure 4 An antenna loop formed by connecting two adjacent antennas is just one example; an antenna loop can also contain two antennas spaced apart. Furthermore, Figure 4 The lower end of the second antenna 42 is connected to a control module (not shown). When a stylus touches the display panel, the information collected by the first antenna circuit 411 is used to determine the position of the touch point in the first direction, and the information collected by the second antenna circuit 421 is used to determine the position of the touch point in the first direction. The two are combined to determine the position information of the touch point.

[0047] It should be noted that the substrate 1 has a display area 11 and a non-display area. The display module 2, the light-sensing module 3, and the touch module 4 are all located within the display area 11. A control module is located in the non-display area and is electrically connected to the display module 2, the light-sensing module 3, and the touch module 4. The light-sensing module 3 and the touch module 4 transmit the collected information to the control module, which analyzes and determines the interaction position. The data line, the first antenna 41, and the second antenna 42 extend from the display area 11 to the non-display area. They can be independently connected to individual control units within the control module, or they can be partially and uniformly connected to the same control unit as needed. This embodiment does not impose specific limitations. The control unit can be COF (Chip On Flex).

[0048] This embodiment combines remote interactive photoelectric sensing control with near-field interactive electromagnetic touch control, providing more interaction methods on the same display panel, thus offering more convenience and possibilities, applicable to more application scenarios, and avoiding the inconvenience caused by a single interaction method.

[0049] In one embodiment, such as Figure 5 As shown, Figure 5 The circuit diagram of the photosensitive module 3 provided in this embodiment is shown. The photosensitive unit 31 includes a photosensitive thin-film transistor T1, a first storage capacitor C1, and a first switching thin-film transistor T2. The data lines may include multiple first power lines 32SVDD, second power lines 33SVGG, and read lines 34RD. The first power line 32SVDD is electrically connected to the source of the photosensitive thin-film transistor T1. The second power line 33SVGG is electrically connected to the gate of the photosensitive thin-film transistor T1 and the first plate of the first storage capacitor C1. The drain of the photosensitive thin-film transistor T1 is connected to the source of the first switching thin-film transistor T2 and the second plate of the first storage capacitor C1. The gate of the first switching thin-film transistor T2 is connected to the scan line Scan, and the drain of the first switching thin-film transistor T2 is connected to the read line 34RD.

[0050] The working principle of the photosensitive module 3 is as follows: the first power line 32SVDD and the second power line 33SVGG are constant voltage sources, and the photosensitive thin-film transistor T1 can always be in the on state, charging the first storage capacitor C1. The first switching thin-film transistor T2 is an addressing switch, and the scan line Scan controls the first switching thin-film transistor T2 to turn on line by line to detect the capacitance of the first storage capacitor C1.

[0051] When light shines on the photosensitive thin-film transistor T1, its leakage current increases, causing a change in the capacitance of the first storage capacitor C1. The first switching thin-film transistor T2 detects this change in the first storage capacitor C1. At this time, the sensing signal read from the first switching thin-film transistor T2 by the readout line 34RD is the sensing signal generated by the photosensitive thin-film transistor T1 due to light illumination. Based on the sensing signal read from the readout line 34RD, the light-sensitive position of the display panel can be determined.

[0052] Furthermore, the display module 2 may include a second switching thin-film transistor T3, a second storage capacitor C2, and a third storage capacitor C3. The second storage capacitor C2 and the third storage capacitor C3 are connected in parallel. The gate of the second switching thin-film transistor T3 is connected to the scan line Scan, the source of the second switching thin-film transistor T3 is connected to the data line Data, and the drain of the second switching thin-film transistor T3 is connected to one end of the second storage capacitor C2 and the third storage capacitor C3. The other ends of the second storage capacitor C2 and the third storage capacitor C3 are grounded. The scan line Scan controls the second switching thin-film transistor T3 to turn on line by line to control the brightness of the corresponding pixel unit 21.

[0053] In one embodiment, the first antenna 41 and the data lines extending along a first direction are both disposed between two adjacent rows of pixel units 21. The extension directions of the first power line 32SVDD, the second power line 33SVGG, and the readout line 34RD within the data lines can be freely configured according to the arrangement space of the display panel. Figure 2 As shown, the first power line 32SVDD, the second power line 33SVGG, and the read line 34RD in the data line all extend along the second direction, that is, each data line is electrically connected to the optical sensing unit 31 in the same column. Figure 6 As shown, the first power line 32SVDD extends along the first direction, and the second power line 33SVGG and the read line 34RD extend along the second direction. Figure 7 As shown, the second power line 33SVGG extends along the first direction, and the first power line 32SVDD and read line 34RD extend along the second direction. Figure 8 As shown, the first power line 32SVDD and the second power line 33SVGG extend along a first direction, and the read line 34RD extends along a second direction. Alternatively, the read line 34RD may also extend along the first direction.

[0054] It should be noted that when there are data lines extending along the first direction, and one photosensitive unit 31 corresponds to multiple rows of pixel units 21, the data lines extending along the first direction can be repeatedly set. However, in practice, only one data line is needed to connect each photosensitive unit 31 to each other. For example... Figure 8As shown, one photosensitive unit 31 corresponds to four rows of pixel units 21. The first power line 32SVDD and the second power line 33SVGG both extend along the first direction. Correspondingly, there is a first power line 32SVDD between the four rows of pixel units 21. The three second power lines 33SVGG are connected to the photosensitive unit 31. However, in reality, only one second power line 33SVGG needs to be set. Considering that the first antenna 41 is also set between two adjacent rows of pixel units 21, the other two second power lines 33SVGG can be replaced with the first antenna 41.

[0055] Furthermore, by placing the data line between any two adjacent rows of pixel units 21, the area occupied by the light-sensing module 3 in the display area 11 can be reduced, thereby increasing the aperture ratio of the display circuit and thus improving the transmittance of the display panel.

[0056] In one embodiment, since the first antenna 41 and the data line extending along the first direction are both arranged between two adjacent rows of pixel units 21, in order to provide arrangement space, the light sensing unit 31 corresponds to at least a preset number of pixel units 21. The preset number of rows is the number of types of connecting lines extending along the first direction. The connecting lines include the first antenna 41 and the data line. The number of types of connecting lines is the number of the first power line 32SVDD, the second power line 33SVGG, and the read line 34RD that are extended along the first direction.

[0057] If all connecting lines extend along the second direction, then only the first antenna 41 extends along the first direction, and the photosensitive unit 31 can correspond to one or more rows of pixel units 21. If any one of the connecting lines—the first power line 32SVDD, the second power line 33SVGG, and the readout line 34RD—extends along the first direction, then the photosensitive unit 31 corresponds to at least two rows of pixel units 21. Similarly, if two of the connecting lines—the first power line 32SVDD, the second power line 33SVGG, and the readout line 34RD—extend along the first direction, then the photosensitive unit 31 corresponds to at least three rows of pixel units 21. If all three connecting lines—the first power line 32SVDD, the second power line 33SVGG, and the readout line 34RD—extend along the first direction, then the photosensitive unit 31 corresponds to at least four rows of pixel units 21.

[0058] In one embodiment, such as Figure 9 and Figure 10 As shown, the display panel includes a gate metal layer 51, a gate insulating layer 52, an active layer 53, a source drain metal layer 54, a passivation layer 55, and a pixel electrode layer 56 stacked on the substrate 1. Among them, 61 is the structure corresponding to the display module 2, and 62 is the structure corresponding to the light sensing module 3.

[0059] The gate metal layer 51 includes multiple patterned gates, such as the gates of the photosensitive thin-film transistor T1, the first switching thin-film transistor T2, and the second switching thin-film transistor T3. The gate metal layer 51 also includes multiple scan lines Scan extending along a first direction and spaced apart in a second direction. The scan lines Scan connect to the gates of the first switching thin-film transistor T2 and the second switching thin-film transistor T3, and are used to transmit scan control signals that control the first switching thin-film transistor T2 and the second switching thin-film transistor T3 to turn on and off.

[0060] The first antenna 41 extends along a first direction and is disposed on the same layer as the gate metal layer 51. Similarly, each data line extending along the first direction is also disposed on the same layer as the gate metal layer 51.

[0061] After the gate metal layer 51 is patterned, it only occupies a part of the substrate 1. Therefore, a gate insulating layer 52 is deposited on the substrate 1 and the gate metal layer 51. The gate insulating layer 52 covers the gate metal layer 51 and the substrate 1. The material on which the gate insulating layer 52 is disposed is SiNx, SiOx or a combination of both.

[0062] The active layer 53 is positioned opposite to the gate of each crystal thin film light. The material of the photosensitive thin film transistor T1 is amorphous silicon (A-Si). Based on the photosensitive properties of amorphous silicon, after the amorphous silicon active layer 53 receives light, photogenerated carriers are generated, causing the current to change, and thus the capacitance of the first storage capacitor C1 changes.

[0063] The source-drain metal layer 54 includes multiple patterned sources and drains, such as the sources and drains of the photosensitive thin-film transistor T1, the first switching thin-film transistor T2, and the second switching thin-film transistor T3. The sources and drains are located at both ends of the active layer 53, with the active layer 53 exposed in the middle. The source-drain metal layer 54 also includes multiple data lines Data extending along a second direction and spaced apart in a first direction. The data lines Data are connected to the source of the second switching thin-film transistor T3, and the drain of the second switching thin-film transistor T3 is electrically connected to the corresponding pixel electrode layer 56. When the second switching thin-film transistor T3 is turned on, the pixel electrode layer 56 can be charged through the data lines Data.

[0064] The second data line 42 extends along the second direction and is disposed on the same layer as the source / drain metal layer 54. Similarly, each data line extending along the second direction is also disposed on the same layer as the source / drain metal layer 54. It should be noted that, as Figure 10 As shown, a metal layer (i.e., metal layer M2 in region 62) is added to the dummy area to create the second antenna 42, which does not occupy the routing space of the data line of the optical sensor module 3.

[0065] The active layer 53 and the source / drain metal layer 54 occupy only a portion of the gate insulating layer 52. Therefore, a passivation layer 55 is deposited on the active layer 53 and the source / drain metal layer 54, covering the active layer 53 and the source / drain metal layer 54. Specifically, the passivation layer 55 has vias in the region corresponding to the source / drain metal layer 54, exposing a portion of the source / drain metal layer 54 for communication between the pixel electrode layer 56 and the source / drain metal layer 54.

[0066] In one embodiment, a metal reflective layer 57 is provided to increase the reflection and utilization of ambient light while reducing energy consumption. The metal reflective layer 57 is made of silver, and to prevent oxidation of the silver layer, it is disposed between the passivation layer 55 and the pixel electrode layer 56. The metal reflective layer 57 utilizes 50% of the area of ​​the color resist. Furthermore, to prevent the metal reflective layer 57 from obstructing the light sensing module 3 from receiving light signals, it has vias to expose the active layer 53 of the light-sensing thin-film transistor T1 for receiving light signals.

[0067] In one embodiment, such as Figure 1 As shown, the touch module 4 also includes a second main antenna 422 electrically connected to multiple second antennas 42. That is, one end of all the second antennas 42 is electrically connected to the same second main antenna 422, and the other end of each second antenna 42 is connected to a control unit in the non-display area. The multiple second antennas 42 form multiple second antenna loops 421 with the second main antenna 422. When the stylus clicks a certain point, the click falls within a specific second antenna loop 421. The electromagnetic signal strength within the corresponding second antenna loop 421 differs, thus determining the position of the stylus click in the second direction. For example... Figure 11 As shown, two second antennas 42 separated by three second antennas 42 form a second antenna loop 421. The two second antennas 42 of the same second antenna loop 421 are connected to the same control unit in the non-display area. When the stylus touches between X5 and X6, the second antenna loop 421 containing the space between X5 and X6 in the figure senses the electromagnetic signal strength, while the other second antenna loops 421 do not, thus determining that the stylus touch is between X5 and X6.

[0068] It should be noted that, in order to make the sensing and positioning more accurate, any two secondary antennas 42 and the second main antenna 422 form a secondary antenna loop 421. The two secondary antennas 42 can be adjacent to each other, or they can be two secondary antennas 42 separated by at least one secondary antenna 42. Figure 11 The second secondary antenna 42, separated by two secondary antennas 42, and the second main antenna 422 form a secondary antenna loop 421. It should be noted that a predetermined number of secondary antennas 42 are spaced apart between the two secondary antennas 42 for more accurate positioning.

[0069] Similarly, similar to the connection method of the second antenna 42, the touch module 4 also includes a first main antenna 412 electrically connected to multiple first antennas 41. Any two of the multiple first antennas 41 and the first main antenna 412 form a first antenna loop 411. The two first antennas 41 can be adjacent to each other, or they can be two first antennas 41 separated by at least one first antenna 41. Likewise, if a preset number of first antennas 41 are spaced apart between the two first antennas 41, the positioning effect will be more accurate.

[0070] In one embodiment, since the first antenna 41 and the data line extending along the first direction are disposed on the same layer, when there is a data line extending along the first direction, the impedance generated by the data line extending along the first direction will affect the acquisition accuracy of the first antenna 41. The first main antenna 412, which is electrically connected to all the first antennas 41, is most affected. Therefore, the first antenna loop 411 is a separate connection between any two first antennas 41, and the two first antennas 41 in the same first antenna loop 411 are connected to the same control unit in the non-display area. Furthermore, to make the sensing and positioning more accurate, the first antenna loop 411 is a separate connection between two first antennas 41. The two first antennas 41 can be adjacent first antennas 41, or they can be two first antennas 41 spaced apart by at least one first antenna 41, such as... Figure 12 As shown in the figure. Among them, the first antennas 41 are spaced apart by a predetermined number of first antennas 41, which results in more accurate positioning and lower impedance.

[0071] This embodiment combines remote interactive photoelectric sensing control with near-field interactive electromagnetic touch control, providing more interaction methods on the same display panel, thus offering more convenience and possibilities, applicable to more application scenarios, and avoiding the inconvenience caused by a single interaction method.
