Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display panel and display device. Background Technology

[0002] With the development of display technology, the thinner and lighter design of display devices and the increase in screen ratio are receiving increasing attention.

[0003] In related technologies, integrating the light sensor into the display screen can effectively reduce the area occupied by the light sensor, increase the screen ratio of the display device, and facilitate the thinning and lightening of the display device.

[0004] However, the light sensors in related technologies are easily affected by the display light, resulting in low accuracy in sensing ambient light. Summary of the Invention

[0005] Based on this, embodiments of this application provide a display panel and a display device that can improve the accuracy of the light sensor in sensing ambient light and improve the display effect of the display panel.

[0006] On one hand, embodiments of this application provide a display panel, including:

[0007] substrate;

[0008] The light-emitting device layer is disposed on one side of the substrate and includes multiple light-emitting devices.

[0009] A touch structure layer is disposed on the side of the light-emitting device layer away from the substrate; the touch structure layer includes a first touch electrode, which includes a plurality of first touch electrodes with the same signal type; the touch structure layer also includes a first photosensitive electrode layer, a semiconductor layer and a second photosensitive electrode layer stacked along the direction away from the substrate; the first photosensitive electrode layer is electrically connected to one of the plurality of first touch electrodes and the second photosensitive electrode layer is electrically connected to the other of the plurality of first touch electrodes;

[0010] The touch structure layer has a first state and a second state. In the first state, the potentials of the first photosensitive electrode and the second photosensitive electrode are the same. In the second state, the potentials of the first photosensitive electrode and the second photosensitive electrode are different, so as to apply a reverse bias voltage between the first photosensitive electrode layer and the second photosensitive electrode layer.

[0011] On the other hand, embodiments of this application provide a display device, including the display panel provided in the foregoing embodiments of this application.

[0012] The display panel and display device provided in this application embodiment utilize a light-emitting device layer disposed on one side of a substrate. This light-emitting device layer includes multiple light-emitting devices, allowing the light emitted by these devices to display an image. A touch structure layer is disposed on the side of the light-emitting device layer facing away from the substrate. This touch structure layer includes multiple first touch electrodes of the same signal type. The touch structure layer also includes a first photosensitive electrode layer, a semiconductor layer, and a second photosensitive electrode layer stacked along a direction away from the substrate. The first photosensitive electrode layer is electrically connected to one of the multiple first touch electrodes, and the second photosensitive electrode layer is electrically connected to another of the multiple first touch electrodes. Thus, the stacked first photosensitive electrode layer, semiconductor layer, and second photosensitive electrode layer can form a photosensitive device within the touch structure layer. Furthermore, the touch structure layer can have a first state and a second state. In the first state, the potentials of the first and second photosensitive electrode layers can be the same. That is, the potentials on the first touch electrodes are the same. In this case, the first and second photosensitive electrode layers can serve as the first touch electrodes of the touch structure. In the second state, the first photosensitive electrode layer and the second photosensitive electrode layer can be charged with different potentials through different first touch electrodes, thereby loading a reverse bias voltage between the first photosensitive electrode layer and the second photosensitive electrode layer; thus, when ambient light shines on the semiconductor layer, a photocurrent can be generated, thereby determining the intensity of the ambient light.

[0013] In other words, in this embodiment of the application, the touch structure layer includes a first photosensitive electrode layer, a semiconductor layer, and a second photosensitive electrode layer stacked along the direction away from the substrate. The first photosensitive electrode layer is electrically connected to one of the first touch electrodes of the touch structure layer, and the second photosensitive electrode layer is electrically connected to the other first touch electrode of the touch structure layer. This allows the photosensitive device to be integrated into the touch structure layer, enabling the touch structure to operate in two different working states to realize touch function and photosensitive function respectively.

[0014] Furthermore, by configuring the touch structure layer to include a first photosensitive electrode layer, a semiconductor layer, and a second photosensitive electrode layer stacked along the direction away from the substrate, the distance between the photosensitive device formed by the first photosensitive electrode layer, the semiconductor layer, and the second photosensitive electrode layer and the touch structure layer is reduced. This reduces the amount of display light (emitted by the light-emitting device) reflected from the touch structure layer to the photosensitive device, lowers the interference caused by reflected display light to the photosensitive device, improves the accuracy of the photosensitive device in sensing ambient light, and enhances the display effect of the display panel.

[0039] Figure 1 This is a cross-sectional view of a display panel provided in some embodiments of this application.

[0040] In some examples, refer to Figure 1 As shown, the display panel 10 may include a substrate 11. The substrate 11 may include either a glass substrate 11 or a flexible substrate 11. It is understood that in some examples of the embodiments of this application, the specific type of the substrate 11 may be the same as, similar to or similar to the type of substrate 11 in the related art. For details, please refer to the detailed description of the related art. The embodiments of this application will not repeat the details in this regard.

[0041] In some examples, refer to Figure 1 As shown, the display panel 10 may include a light-emitting device layer 12. The light-emitting device layer 12 may be disposed on one side of the substrate 11.

[0042] In some examples, the light-emitting device layer 12 may include a plurality of light-emitting devices 121. The light-emitting devices 121 may include any one of a light-emitting diode (LED), an organic light-emitting diode (OLED), or a micro-organic light-emitting diode (Micro OLED).

[0043] It is understood that in some examples of the embodiments of this application, the specific type of the light-emitting device 121 is only used as a specific example for illustration, and is not a limitation on the specific type of the light-emitting device 121.

[0044] In some examples, multiple light-emitting devices 121 may be arranged in an array on one side of the substrate 11. At least some of the multiple light-emitting devices 121 may emit light of different colors, thereby enabling the display panel 10 to display images of different colors.

[0045] In some examples, refer to Figure 1 As shown, the display panel 10 may include a touch structure layer 13. The touch structure layer 13 may be disposed on the side of the light-emitting device layer 12 opposite to the substrate 11.

[0046] It is understood that in some examples of the embodiments of this application, other layer structures may be provided between the touch structure layer 13 and the light-emitting device layer 12. For example, an encapsulation layer may be provided between the touch structure layer 13 and the light-emitting device layer 12.

[0047] Figure 2 This is a schematic diagram of a touch structure layer in a display panel provided in some embodiments of this application.

[0048] In some examples, refer to Figure 2 As shown, the touch structure layer 13 may include a first touch electrode 131. Multiple first touch electrodes 131 with the same signal type may be provided. For example, the first touch electrode 131 may be used to transmit a transmitted signal; or, the first touch electrode 131 may be used to transmit a received signal.

[0049] In some examples, refer to Figure 1 As shown, in order to reduce the area occupied by the photosensitive device 14 and increase the screen ratio of the display panel 10, the photosensitive device 14 is usually placed under the screen.

[0050] In some examples, refer to Figure 1 As shown, the photosensitive device 14 can be disposed on the side of the light-emitting device layer 12 facing the substrate 11. The light-emitting device layer 12 can be provided with a through-hole 122 for ambient light to enter. (Refer to...) Figure 1As shown, ambient light can travel along... Figure 1 The light shines into the display panel 10 in the direction indicated by the middle arrow a and is received by the photosensitive device 14.

[0051] In some examples, the photosensitive device 14 can generate an electrical signal corresponding to the intensity of the ambient light after receiving ambient light. The display panel 10 can determine the intensity of the current ambient light based on the electrical signal generated by the photosensitive device 14, and adjust the display brightness of the display panel 10 according to the intensity of the ambient light, thereby improving the display effect and user experience of the display panel 10.

[0052] However, refer to Figure 1 As shown, during the transmission of light emitted by the light-emitting device 121 to the external environment, the divergent display light may illuminate the touch structure layer 13 and be reflected by it. For example, see reference... Figure 1 As shown, the light may travel along... Figure 1 The light emitted in the direction indicated by arrow b is reflected to and received by the photosensitive device 14. At this time, the electrical signal generated by the photosensitive device 14 may contain signals generated by both ambient light and display light. This causes interference in the display panel 10's judgment of ambient light intensity, resulting in lower accuracy in sensing ambient light.

[0053] Figure 3 This is another cross-sectional view of the display panel provided in some embodiments of this application.

[0054] In some examples, refer to Figure 3 As shown, the touch structure layer 13 may include a first photosensitive electrode layer 141. The first photosensitive electrode layer 141 may be electrically connected to one of the plurality of first touch electrodes 131.

[0055] In some examples, the material of the first photosensitive electrode layer 141 may be the same as, similar to or similar to the material of the first touch electrode 131.

[0056] In some examples, the first photosensitive electrode layer 141 may be made of an opaque conductive material.

[0057] In some examples, the first photosensitive electrode layer 141 may be located on the side of the light-emitting device layer 12 away from the substrate 11.

[0058] In some examples, the touch structure layer 13 may include a semiconductor layer 142. The semiconductor layer 142 may be located on the side of the first photosensitive electrode layer 141 facing away from the substrate 11. That is, the first photosensitive electrode layer 141 and the semiconductor layer 142 may be stacked in a direction away from the substrate 11.

[0059] In some examples, the touch structure layer 13 may include a second photosensitive electrode layer 143. The second photosensitive electrode layer 143 may be located on the side of the semiconductor layer 142 facing away from the substrate 11. That is, the first photosensitive electrode layer 141, the semiconductor layer 142, and the second photosensitive electrode layer 143 may be stacked in a direction away from the substrate 11. In this way, the first photosensitive electrode layer 141, the semiconductor layer 142, and the second photosensitive electrode layer 143 can be constructed to form a photosensitive device 14.

[0060] In some examples, the second photosensitive electrode layer 143 may be electrically connected to another of the plurality of first touch electrodes 131. That is, in some examples of embodiments of this application, the first photosensitive electrode layer 141 and the second photosensitive electrode layer 143 may be electrically connected to different first touch electrodes 131 respectively.

[0061] In some examples, the touch structure layer 13 may have a first state. In the first state, the potentials of the first photosensitive electrode layer 141 and the second photosensitive electrode layer 143 may be the same. That is, in the first state, the first touch electrode 131 electrically connected to the first photosensitive electrode layer 141 can transmit either a transmit signal or a receive signal, and the first touch electrode 131 electrically connected to the second photosensitive electrode layer 143 can transmit the same signal type as the first touch electrode 131 electrically connected to the first photosensitive electrode layer 141. For example, the first touch electrode 131 electrically connected to the first photosensitive electrode layer 141 can transmit a transmit signal, and in this case, the first touch electrode 131 electrically connected to the second photosensitive electrode layer 143 can also transmit a transmit signal. Alternatively, the first touch electrode 131 electrically connected to the first photosensitive electrode layer 141 can transmit a receive signal, and in this case, the first touch electrode 131 electrically connected to the second photosensitive electrode layer 143 can also transmit a receive signal.

[0062] In some examples, in the first state, the potentials of the first photosensitive electrode layer 141 and the second photosensitive electrode layer 143 can be the same. The photosensitive device 14 formed by the first photosensitive electrode layer 141, the semiconductor layer 142 and the second photosensitive electrode layer 143 will not generate photocurrent. The first photosensitive electrode layer 141 and the second photosensitive electrode layer 143 are used as two different first touch electrodes 131 of the touch structure layer 13.

[0063] In some examples, the touch structure layer 13 may have a second state. In the second state, the potentials of the first photosensitive electrode layer 141 and the second photosensitive electrode layer 143 may be different. Thus, a reverse bias voltage can be applied between the first photosensitive electrode layer 141 and the second photosensitive electrode layer 143, thereby giving the photosensitive device 14 formed by the first photosensitive electrode layer 141, the semiconductor layer 142, and the second photosensitive electrode layer 143 a reverse bias voltage, enabling it to convert received light energy into electrical energy, thereby generating a photocurrent, which facilitates the detection of ambient light intensity.

[0064] In some examples of embodiments of this application, a first photosensitive electrode layer 141, a semiconductor layer 142, and a second photosensitive electrode layer 143 are stacked along a direction away from the substrate 11 in the touch structure layer 13. The first photosensitive electrode layer 141 is electrically connected to one of the plurality of first touch electrodes 131, and the second photosensitive electrode layer 143 is electrically connected to another of the plurality of first touch electrodes 131. Thus, when the touch structure layer 13 is in the second state, the light emitted by the light-emitting device 121, after being reflected by the first touch electrode 131, will not illuminate the photosensitive device 14 formed by the first photosensitive electrode layer 141, the semiconductor layer 142, and the second photosensitive electrode layer 143. This reduces the interference of display light on the photosensitive device 14, improves the accuracy of the photosensitive device 14 in sensing ambient light, and enhances the display effect and user experience of the display panel 10.

[0065] The display panel 10 provided in some examples of embodiments of this application provides a light-emitting device layer 12 on one side of a substrate 11. The light-emitting device layer 12 includes a plurality of light-emitting devices 121, so that the light emitted by the light-emitting devices 121 can display an image. A touch structure layer 13 is provided on the side of the light-emitting device layer 12 away from the substrate 11. The touch structure layer 13 includes a plurality of first touch electrodes 131 with the same signal type. The touch structure layer 13 also includes a first photosensitive electrode layer 141, a semiconductor layer 142, and a second photosensitive electrode layer 143 stacked in a direction away from the substrate 11. The first photosensitive electrode layer 141 is electrically connected to one of the plurality of first touch electrodes 131, and the second photosensitive electrode layer 143 is electrically connected to the other of the plurality of first touch electrodes 131. Thus, the stacked first photosensitive electrode layer 141, semiconductor layer 142, and second photosensitive electrode layer 143 can be used to construct a photosensitive device 14 within the touch structure layer 13. Furthermore, the touch structure layer 13 can have a first state and a second state. In the first state, the potentials of the first photosensitive electrode layer 141 and the second photosensitive electrode layer 143 can be the same. That is, the potentials on the first touch electrode 131 are the same. At this time, the first photosensitive electrode layer 141 and the second photosensitive electrode layer 143 can serve as the first touch electrode 131 of the touch structure layer 13. In the second state, the first photosensitive electrode layer 141 and the second photosensitive electrode layer 143 can be charged with different potentials through different first touch electrodes 131, thereby applying a reverse bias voltage between the first photosensitive electrode layer 141 and the second photosensitive electrode layer 143. Thus, when ambient light shines on the semiconductor layer 142, a photocurrent can be generated, thereby determining the intensity of the ambient light.

[0066] In other words, in this embodiment, the touch structure layer 13 includes a first photosensitive electrode layer 141, a semiconductor layer 142, and a second photosensitive electrode layer 143 stacked along a direction away from the substrate 11. The first photosensitive electrode layer 141 is electrically connected to one of the first touch electrodes 131 of the touch structure layer 13, and the second photosensitive electrode layer 143 is electrically connected to the other first touch electrode 131 of the touch structure layer 13. This allows the photosensitive device 14 to be integrated into the touch structure layer 13, enabling the touch structure layer 13 to operate in two different states to achieve touch and light-sensing functions respectively. This reduces the amount of display light (emitted by the light-emitting device 121) reflected from the touch structure layer 13 to the photosensitive device 14, reducing interference from reflected display light on the photosensitive device 14, improving the accuracy of the photosensitive device 14 in sensing ambient light, and enhancing the display effect of the display panel 10.

[0067] In some examples, the first photosensitive electrode layer 141 can be a light-shielding conductive layer. The first photosensitive electrode layer 141 can be made of an opaque metallic material. For example, the first photosensitive electrode layer 141 can be made of molybdenum.

[0068] In some examples, the transmittance of the light-shielding conductive layer can be less than 10%.

[0069] In some examples, the second photosensitive electrode layer 143 can be a light-transmitting conductive layer. The second photosensitive electrode layer 143 can be made of a light-transmitting conductive material. For example, the second photosensitive electrode layer 143 can be made of indium tin oxide (ITO).

[0070] In some examples, the transmittance of the second photosensitive electrode layer 143 can be greater than 85%.

[0071] In some examples of embodiments of this application, the first photosensitive electrode layer 141 is configured as a light-shielding conductive layer. Thus, when the display light emitted by the light-emitting device 121 illuminates the first photosensitive electrode layer 141, it can be blocked by the first photosensitive electrode layer 141, reducing interference caused by the display light to the photosensitive device 14. This improves the accuracy of the photosensitive device 14 in sensing ambient light, thereby enhancing the display effect and user experience of the display panel 10. Alternatively, the second photosensitive electrode layer 143 is configured as a light-transmitting conductive layer. Thus, when ambient light illuminates the display panel 10, it can pass through the second photosensitive electrode layer 143 and illuminate the semiconductor layer 142, generating a photocurrent. This improves the reception of ambient light by the semiconductor layer 142, enhancing the accuracy of the photosensitive device 14 in sensing ambient light. This further improves the display effect and user experience of the display panel 10.

[0072] In some examples, refer to Figure 3 As shown, the first touch electrode 131 can be located on the side of the light-emitting device layer 12 away from the substrate 11. The first photosensitive electrode layer 141 can be located on the side of the light-emitting device layer 12 away from the substrate 11. That is, in some examples of the embodiments of this application, the first touch electrode 131 and the first photosensitive electrode layer 141 can be disposed on the same layer. In a specific configuration, the first photosensitive electrode layer 141 can be formed simultaneously with the first touch electrode 131 on the side of the light-emitting device layer 12 away from the substrate 11, thereby constructing the first touch electrode 131 and the first photosensitive electrode layer 141.

[0073] In some embodiments of this application, the first touch electrode 131 is positioned on the side of the light-emitting device layer 12 facing away from the substrate 11, and the first photosensitive electrode layer 141 is positioned on the side of the light-emitting device layer 12 facing away from the substrate 11. This allows the first touch electrode 131 and the first photosensitive electrode layer 141 to be disposed on the same layer. This facilitates the formation and placement of the first photosensitive electrode layer 141, improves the manufacturing efficiency of the display panel 10, simplifies the manufacturing process of the display panel 10, and saves on the manufacturing costs of the display panel 10.

[0074] In some examples, refer to Figure 3 As shown, the display panel 10 may include a light-shielding layer 15. The light-shielding layer 15 may be disposed between the touch structure layer 13 and the light-emitting device layer 12.

[0075] In some examples, the light-shielding layer 15 may be made of a black material. The light transmittance of the light-shielding layer 15 may be less than 0.01%.

[0076] In some examples, refer to Figure 3 As shown, the light-shielding layer 15 may have a first light-transmitting opening 151. Along the thickness direction of the substrate 11 (e.g., along the thickness direction of the substrate 11) Figure 3 (In the direction indicated by the y-axis) The first light-transmitting opening 151 can be opposite to the light-emitting device 121. That is, the light emitted by the light-emitting device 121 can be transmitted to the outside of the display panel 10 through the first light-transmitting opening 151.

[0077] It is understood that in some examples of embodiments of this application, multiple first light-transmitting openings 151 may be provided. One first light-transmitting opening 151 may be opposite to one light-emitting device 121.

[0078] In some examples, the light-shielding layer 15 may have a first orthographic projection on the substrate 11. The first orthographic projection may be located between the orthographic projections of two adjacent light-emitting devices 121 on the substrate 11.

[0079] In some examples, any one of the first photosensitive electrode layer 141, the semiconductor layer 142, and the second photosensitive electrode layer 143 may have a second orthographic projection on the substrate 11. The first orthographic projection may cover the second orthographic projection. That is, the light-shielding layer 15 may be positioned between the light-emitting device layer 12 and the first photosensitive electrode layer 141 to block the light from the light-emitting device layer 12 illuminating the first photosensitive electrode layer 141.

[0080] In some examples of embodiments of this application, a light-shielding layer 15 is provided between the touch structure layer 13 and the light-emitting device layer 12. The light-shielding layer 15 has a first light-transmitting opening 151, which is opposite to the light-emitting device 121 along the thickness direction of the substrate 11. Thus, the light emitted by the light-emitting device 121 can shine through the first light-transmitting opening 151 to the outside of the display panel 10, ensuring the normal display of the display panel 10. The light-shielding layer 15 has a first orthographic projection on the substrate 11, and any one of the first photosensitive electrode layer 141, the semiconductor layer 142, and the second photosensitive electrode layer 143 has a second orthographic projection on the substrate 11. In some examples of embodiments of this application, the first orthographic projection is configured to cover the second orthographic projection. This ensures that the light-shielding layer 15 blocks the light-emitting device layer 12 and the first photosensitive electrode layer 141. The light emitted by the light-emitting device 121 can be blocked from shining on the first photosensitive electrode layer 141, which can reduce the interference of display light on the photosensitive device 14, ensure the accuracy of the photosensitive device 14 in sensing ambient light, and improve the display effect and user experience of the display panel 10.

[0081] In some examples, the first touch electrode 131 may have a third orthographic projection on the substrate 11. The first orthographic projection may cover the third orthographic projection. That is, in some examples of embodiments of this application, the light-shielding layer 15 may block the light-emitting device layer 12 and the first touch electrode 131.

[0082] In some examples, the light-shielding layer 15 can block the light-emitting device layer 12 from the first touch electrode 131 and the first photosensitive electrode layer 141. That is, the light-shielding layer 15 can simultaneously block the first touch electrode 131 and the first photosensitive electrode layer 141.

[0083] In some examples of embodiments of this application, the first touch electrode 131 has a third orthographic projection on the substrate 11. The first orthographic projection is configured to cover the third orthographic projection. This blocks the light emitted by the light-emitting device 121 to the first touch electrode 131, reducing the reflection of light emitted by the light-emitting device 121 by the first touch electrode 131. This reduces interference from reflected light on the photosensitive device 14, improving the display effect and user experience of the display panel 10.

[0084] In some examples, refer to Figure 3 As shown, the second photosensitive electrode layer 143 can have a first preset distance d1 between the side facing the first light-transmitting opening 151 and the first light-transmitting opening 151.

[0085] In some examples, the first preset distance d1 can be the minimum distance between the side of the second photosensitive electrode layer 143 facing the first light-transmitting opening 151 and the first light-transmitting opening 151.

[0086] In some examples, the first preset distance d1 can be the minimum distance between the side of the second photosensitive electrode layer 143 facing the first light-transmitting opening 151 and the opening edge of the first light-transmitting opening 151.

[0087] In some examples, the first preset distance d1 can be greater than zero. That is, the side of the second photosensitive electrode layer 143 facing the first light-transmitting opening 151 can be positioned away from the first light-transmitting opening 151 relative to the edge of the first light-transmitting opening 151 in a direction away from the first light-transmitting opening 151.

[0088] In some examples, during setup, after forming the touch structure layer 13 on the light-shielding layer 15, the second photosensitive electrode layer 143 can be removed from the side facing the first light-transmitting opening 151 during the patterning process of the touch structure layer 13, so that the side of the second photosensitive electrode layer 143 facing the first light-transmitting opening 151 can have a first preset distance d1 between it and the first light-transmitting opening 151.

[0089] In some examples of embodiments of this application, a first preset distance d1 is set between the side of the second photosensitive electrode layer 143 facing the first light-transmitting opening 151 and the first light-transmitting opening 151, and the first preset distance d1 is set to be greater than zero. This ensures that the side of the stacked first photosensitive electrode layer 141, semiconductor layer 142, and second photosensitive electrode layer 143 facing the first light-transmitting opening 151 is all at a certain distance from the first light-transmitting opening 151; this reduces the amount of divergent light emitted by the light-emitting device 121 illuminating the photosensitive device 14, reduces interference from display light on the light-emitting device 121, improves the accuracy of the light-emitting device 121 in sensing ambient light, and enhances the display effect and user experience of the display panel 10.

[0090] In some examples, refer to Figure 3 As shown, along the arrangement direction of the light-emitting devices 121 (e.g.) Figure 3 (in the direction shown by the x-axis), the side of the light-emitting device 121 away from the second photosensitive electrode layer 143 and the side wall of the first light-transmitting opening 151 that opens into the second photosensitive electrode layer 143 may have a first virtual connection i.

[0091] In some examples, when the first virtual connection i passes through the side of the second photosensitive electrode layer 143 facing the first light-transmitting opening 151, there may be a second preset distance d2 between the side of the second photosensitive electrode layer 143 facing the first light-transmitting opening 151 and the first light-transmitting opening 151.

[0092] In some examples, the first preset distance d1 can be greater than or equal to the second preset distance d2.

[0093] In some examples, the first preset distance d1 can be equal to the second preset distance d2.

[0094] In some examples, the first preset distance d1 can be greater than the second preset distance d2.

[0095] In some examples of embodiments of this application, along the arrangement direction of the light-emitting device 121, the line connecting the side of the light-emitting device 121 away from the second photosensitive electrode layer 143 and the sidewall of the first light-transmitting opening 151 near the second photosensitive electrode layer 143 is designated as a first virtual connection line i. When the first virtual connection line i passes through the side of the second photosensitive electrode layer 143 facing the first light-transmitting opening 151, there is a second preset distance d2 between the side of the second photosensitive electrode layer 143 facing the first light-transmitting opening 151 and the first light-transmitting opening 151. In some examples of embodiments of this application, the first preset distance d1 is set to be greater than or equal to the second preset distance d2. In this way, the diffused light emitted by the light-emitting device 121 can be blocked by the light-shielding layer 15, which can reduce the occurrence of light emitted by the light-emitting device 121 hitting the second photosensitive electrode layer 143, reduce the interference of the display light emitted by the light-emitting device 121 on the photosensitive device 14, improve the accuracy of the photosensitive device 14 in sensing ambient light, and improve the display effect and user experience of the display panel 10.

[0096] In some examples, the display panel 10 may include an anti-reflection layer (not shown). The anti-reflection layer may be disposed on the side of the touch structure layer 13 opposite to the substrate 11.

[0097] In some examples, the antireflection layer may include a polarizer. The antireflection layer may be connected to the touch structure layer 13 via an optical adhesive layer.

[0098] In some examples of embodiments of this application, an anti-reflection layer is provided on the side of the touch structure layer 13 facing away from the substrate 11. In this way, after ambient light shines on the first touch electrode 131, the ambient light reflected by the first touch electrode 131 can be blocked by the anti-reflection layer, which can reduce the ambient light reflected from the first touch electrode 131 to the outside of the display panel 10 and improve the display effect of the display panel 10.

[0099] In some examples, refer to Figure 2 and Figure 3 As shown, the touch structure layer 13 may include a second touch electrode 132. The arrangement of the second touch electrode 132 may be the same as, similar to or similar to that of the first touch electrode 131. For details, please refer to the detailed description of the first touch electrode 131 in the foregoing embodiments of this application. This application will not repeat the details in this embodiment.

[0100] In some examples, the types of signals transmitted by the first touch electrode 131 and the second touch electrode 132 may be different. For example, the first touch electrode 131 may transmit a transmit signal, and the second touch electrode 132 may transmit a receive signal. Alternatively, the first touch electrode 131 may transmit a receive signal, and the second touch electrode 132 may transmit a transmit signal.

[0101] In some examples, refer to Figure 2 As shown, the extension direction of the first touch electrode 131 may intersect with the extension direction of the second touch electrode 132.

[0102] In some examples, the extension direction of the first touch electrode 131 may be perpendicular to the extension direction of the second touch electrode 132.

[0103] In some examples, the second touch electrode 132 and the first touch electrode 131 can be stacked along the thickness direction of the substrate 11. For example, the first touch electrode 131 can be located on the side of the light-emitting device layer 12 facing away from the substrate 11, and the second touch electrode 132 can be located on the side of the first touch electrode 131 facing away from the substrate 11. Alternatively, the second touch electrode 132 can be located on the side of the light-emitting device layer 12 facing away from the substrate 11, and the first touch electrode 131 can be located on the side of the second touch electrode 132 facing away from the substrate 11.

[0104] In some examples, the touch structure layer 13 may include an insulating layer 133. The insulating layer 133 may be located between the first touch electrode 131 and the second touch electrode 132. That is, when the first touch electrode 131 is located on the side of the light-emitting device layer 12 away from the substrate 11, the insulating layer 133 may be located on the side of the first touch electrode 131 away from the substrate 11, and the second touch electrode 132 may be located on the side of the insulating layer 133 away from the first touch electrode 131. Alternatively, when the second touch electrode 132 is located on the side of the light-emitting device layer 12 away from the substrate 11, the insulating layer 133 may be located on the side of the second touch electrode 132 away from the substrate 11, and the first touch electrode 131 may be located on the side of the insulating layer 133 away from the first touch electrode 131.

[0105] In some examples of embodiments of this application, a second touch electrode 132 and an insulating layer 133 are provided, with the second touch electrode 132 and the first touch electrode 131 stacked along the thickness direction of the substrate 11, and the insulating layer 133 located between the first touch electrode 131 and the second touch electrode 132. Thus, the first touch electrode 131 and the second touch electrode 132 can transmit different signal types respectively, allowing a longitudinal capacitance to be formed between the first touch electrode 131 and the second touch electrode 132 when the touch structure layer 13 is in the first state, facilitating precise positioning of the touch location.

[0106] In some examples, refer to Figure 2 As shown, the touch structure layer 13 may include a first conductive filling structure 134. The first conductive filling structure 134 may be disposed in the same layer as the first touch electrode 131.

[0107] In some examples, the first filling conductive structure 134 can optimize the uniformity of the manufacturing process of the first touch electrode 131 and improve electrical performance. For example, the first filling conductive structure 134 can balance the layout density of the first touch electrode 131, avoid over-etching or under-etching when patterning the first touch electrode 131, and reduce the impact of reflection or diffraction during photolithography on the accuracy of patterning.

[0108] In some examples, the first conductive filling structure 134 can be reused as the first photosensitive electrode layer 141. That is, the first conductive filling structure 134 can be electrically connected to one of the first touch electrodes 131.

[0109] In some examples, the touch structure layer 13 may include a second conductive filler structure 135. The second conductive filler structure 135 may be disposed in the same layer as the second touch electrode 132.

[0110] It is understood that in some examples of the embodiments of this application, the setting method of the second filling conductive structure 135 may be the same as, similar to or similar to the setting method of the first filling conductive structure 134 in the foregoing embodiments of this application. For details, please refer to the detailed description of the foregoing embodiments of this application. The embodiments of this application will not repeat the details here.

[0111] In some examples, the second conductive filling structure 135 can be reused as the second photosensitive electrode layer 143. That is, the second conductive filling structure 135 can be electrically connected to another first touch electrode 131.

[0112] In some examples, the first touch electrode 131 is located on the side of the light-emitting device layer 12 away from the substrate 11 as a specific example. In some examples of embodiments of this application, a first filling conductive structure 134 may be formed during the process of forming and patterning the first touch electrode 131 on the side of the light-emitting device layer 12 away from the substrate 11. The first filling conductive structure 134 may be electrically connected to one of the first touch electrodes 131; thereby, the first filling conductive structure 134 is reused as a first photosensitive electrode layer 141.

[0113] In some examples, after the first touch electrode 131 and the first photosensitive electrode layer 141 are formed, an insulating layer 133 can be formed on the first touch electrode 131. Then, the insulating layer 133 corresponding to the first filled conductive structure 134 can be removed, and a semiconductor layer 142 can be formed on the first filled conductive structure 134.

[0114] In some examples, the thickness of the semiconductor layer 142 may be the same as the thickness of the insulating layer 133.

[0115] In some examples, the thickness of the semiconductor layer 142 may be different from the thickness of the insulating layer 133.

[0116] In some examples, after the semiconductor layer 142 is formed, a second touch electrode 132 can be formed on the insulating layer 133 and the semiconductor layer 142, and a second filled conductive structure 135 can be formed.

[0117] In some examples of embodiments of this application, a first conductive filling structure 134 and a second conductive filling structure 135 are provided. The first conductive filling structure 134 is disposed in the same layer as the first touch electrode 131, and the second conductive filling structure 135 is disposed in the same layer as the second touch electrode 132. In this way, the uniformity of the manufacturing process of the touch structure layer 13 and the electrical performance can be optimized by utilizing the first conductive filling structure 134 and the second conductive filling structure 135. This avoids over-etching or under-etching during the patterning of the touch structure layer 13, and reduces the impact of reflection or diffraction during photolithography on the patterning accuracy. Furthermore, the first conductive filling structure 134 can shield noise interference signals.

[0118] Alternatively, the first conductive filling structure 134 can be reused as the first photosensitive electrode layer 141, and the second conductive filling structure 135 can be reused as the second photosensitive electrode layer 143. In this way, the first photosensitive electrode layer 141 can be formed simultaneously with the first touch electrode 131, and the second photosensitive electrode layer 143 can be formed simultaneously with the second touch electrode 132. This simplifies the formation of the first and second photosensitive electrode layers 141 and 143, simplifies the manufacturing process of the display panel 10, and saves on the production costs of the display panel 10.

[0119] Figure 4 This is yet another cross-sectional view of the display panel provided in some embodiments of this application. Figure 5 This is yet another cross-sectional view of the display panel provided in some embodiments of this application.

[0120] In some examples, refer to Figures 3-5 As shown, the display panel 10 may include a color filter layer 16. The color filter layer 16 may be disposed on the side of the touch structure layer 13 opposite to the substrate 11.

[0121] In some examples, the color filter layer 16 may have a fourth orthographic projection on the substrate 11. This fourth orthographic projection may overlay the second orthographic projection. That is, along the thickness direction of the substrate 11 (e.g., ...). Figure 3 (in the direction shown by the y-axis), the color filter layer 16 can be stacked on the side of the second photosensitive electrode layer 143 away from the substrate 11.

[0122] In some examples, the color filter layer 16 can be of different colors. In this way, ambient light can be colored green by the color filter layer 16, so that the photosensitive device 14 corresponding to the color filter layer 16 can receive light of a specific color.

[0123] In some examples of embodiments of this application, a color filter layer 16 is provided on the side of the touch structure layer 13 facing away from the substrate 11. The fourth orthographic projection of the color filter layer 16 on the substrate 11 covers the second orthographic projection. In this way, the ambient light incident on the photosensitive device 14 can be filtered by the color filter layer 16, so that the photosensitive device 14 under different color color filter layers 16 can receive different colors of light. This allows the color temperature of the current ambient light to be determined based on the intensity of different colors of light, facilitating the adjustment of the display color temperature of the display panel 10. This improves the display effect and user experience of the display panel 10.

[0124] In some examples, a first photosensitive electrode layer 141, a semiconductor layer 142, and a second photosensitive electrode layer 143 are constructed to form a photosensitive device 14.

[0125] In some examples, the photosensitive device 14 may include a first sub-device 144. The color filter layer 16 may include a first sub-color filter 161. The first sub-color filter 161 may be located in the incident light path of the first sub-device 144. That is, ambient light incident on the first sub-device 144 can be filtered by the first sub-color filter 161 before being incident on the first sub-device 144. The first sub-device 144 can receive ambient light of the same color as the filtered light from the first sub-color filter 161.

[0126] In some examples, the photosensitive device 14 may include a second sub-device 145. The color filter layer 16 may include a second sub-color filter 162. The second sub-color filter 162 may be located in the incident light path of the second sub-device 145. That is, ambient light incident on the second sub-device 145 can be filtered by the second sub-color filter 162 before being incident on the second sub-device 145.

[0127] In some examples, the color of the second sub-color filter 162 may be different from the color of the first sub-color filter 161.

[0128] In some examples, photosensitive device 14 may include a third sub-device 146. Color filter layer 16 may include a third sub-color filter 163. The third sub-color filter 163 may be located on the incident light path of the third sub-device 146.

[0129] In some examples, the color of the third sub-color filter 163 may be different from both the first sub-color filter 161 and the second sub-color filter 162.

[0130] In some examples, the first sub-color filter 161 can be a red (R) color filter; the second sub-color filter 162 can be a green (G) color filter; and the third sub-color filter 163 can be a blue (B) color filter.

[0131] It is understood that in some examples of the embodiments of this application, the colors of the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163 are only shown as specific examples and are not intended to limit the colors of the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163.

[0132] In some examples of embodiments of this application, a first sub-color filter 161 is provided on the light incident path of the first sub-device 144, a second sub-color filter 162 is provided on the light incident path of the second sub-device 145, and a third sub-color filter 163 is provided on the light incident path of the third sub-device 146; the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163 have different colors. Thus, the first sub-device 144 can receive ambient light filtered by the first sub-color filter 161, the second sub-device 145 can receive ambient light filtered by the second sub-color filter 162, and the third sub-device 146 can receive ambient light filtered by the third sub-color filter 163. In other words, the first sub-device 144, the second sub-device 145, and the third sub-device 146 can each receive ambient light of different colors. Therefore, the intensity of different colors of light in the ambient light can be determined by the intensity of the photocurrent generated by the first sub-device 144, the second sub-device 145, and the third sub-device 146, thereby determining the color temperature of the ambient light. This allows the display panel 10 to adjust its display color temperature according to the color temperature of the ambient light, improving the display effect and user experience of the display panel 10.

[0133] In some examples, refer to Figures 3-5 As shown, the plurality of light-emitting devices 121 may include a first light-emitting device 121a, a second light-emitting device 121b, and a third light-emitting device 121c. The first light-emitting device 121a, the second light-emitting device 121b, and the third light-emitting device 121c can emit different colors of light. For example, the first light-emitting device 121a can emit red (R) light, the second light-emitting device 121b can emit green (G) light, and the third light-emitting device 121c can emit blue (B) light. It is understood that the emission colors of the first light-emitting device 121a, the second light-emitting device 121b, and the third light-emitting device 121c are only shown as specific examples and are not intended to limit the color of the light emitted by the light-emitting devices 121.

[0134] Figure 6 This is a diagram showing an arrangement of the first sub-color filter, the second sub-color filter, and the third sub-color filter in a display panel provided in some embodiments of this application. Figure 7This is a diagram showing another arrangement of the first sub-color filter, the second sub-color filter, and the third sub-color filter in a display panel provided in some embodiments of this application.

[0135] In some examples, refer to Figure 6 As shown, the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163 can be arranged along a first direction of the display panel 10 (e.g., the long side direction of the display panel 10). The first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163 can cover the entire display area of ​​the display panel 10.

[0136] In some examples, refer to Figure 7 As shown, the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163 can be arranged along a second direction of the display panel 10 (for example, the short side direction of the display panel 10). The first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163 can cover the entire display area of ​​the display panel 10.

[0137] In some examples, any one of the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163 can be located in the light output path of the first light-emitting device 121a, the second light-emitting device 121b, and the third light-emitting device 121c.

[0138] In some examples, the first sub-color filter 161 can be located in the light-emitting path of the first light-emitting device 121a, the second light-emitting device 121b, and the third light-emitting device 121c. That is, the coverage area of ​​the first sub-color filter 161 can cover the first light-emitting device 121a, the second light-emitting device 121b, and the third light-emitting device 121c.

[0139] In some examples, the second sub-color filter 162 may be located in the light output path of the first light-emitting device 121a, the second light-emitting device 121b, and the third light-emitting device 121c.

[0140] In some examples, the third sub-color filter 163 may be located in the light output path of the first light-emitting device 121a, the second light-emitting device 121b, and the third light-emitting device 121c.

[0141] Figure 8 This is an enlarged structural schematic diagram of the first sub-color filter in a display panel provided in some embodiments of this application. Figure 9 This is an enlarged structural schematic diagram of the second sub-color filter in a display panel provided in some embodiments of this application. Figure 10This is an enlarged structural schematic diagram of the third sub-color filter in a display panel provided in some embodiments of this application.

[0142] In some examples, refer to Figures 8-10 As shown, any one of the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163 may be provided with a second light-transmitting opening 165.

[0143] In some examples, the second light-transmitting opening 165 can be opposite to the light-emitting device 121 along the thickness direction of the substrate 11. That is, the light emitted by the first light-emitting device 121a can be transmitted to the outside of the display panel 10 through the second light-transmitting opening 165 without being filtered by any one of the first sub-color filters 161, the second sub-color filters 162, and the third sub-color filters 163; the light emitted by the second light-emitting device 121b can be transmitted to the outside of the display panel 10 through the second light-transmitting opening 165 without being filtered by any one of the first sub-color filters 161, the second sub-color filters 162, and the third sub-color filters 163; and the light emitted by the third light-emitting device 121c can be directly disposed outside the display panel 10 through the second light-transmitting opening 165 without being filtered by any one of the first sub-color filters 161, the second sub-color filters 162, and the third sub-color filters 163.

[0144] In some examples of embodiments of this application, the plurality of light-emitting devices 121 include a first light-emitting device 121a, a second light-emitting device 121b, and a third light-emitting device 121c, which emit light of different colors. Thus, different colors can be displayed by mixing the light emitted by the first light-emitting device 121a, the second light-emitting device 121b, and the third light-emitting device 121c, thereby enhancing the richness of the colors displayed on the display panel 10 and improving the display effect of the display panel 10.

[0145] In addition, any one of the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163 is located on the light emission path of the first light-emitting device 121a, the second light-emitting device 121b, and the third light-emitting device 121c. A second light-transmitting opening 165 is provided in any one of the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163. Along the thickness direction of the substrate 11, the second light-transmitting opening 165 is opposite to the light-emitting device 121. This facilitates the overall installation of the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163, improving the installation efficiency of the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163. Furthermore, by setting a second light-transmitting opening 165 on any one of the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163, and the second light-transmitting opening 165 being opposite to the light-emitting device 121, the different colors of light emitted by the first light-emitting device 121a, the second light-emitting device 121b, and the third light-emitting device 121c can be smoothly transmitted through the second light-transmitting opening 165 to the outside of the display panel 10. This avoids the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163 blocking the different colors of light emitted by the light-emitting device 121, ensuring the display effect of the display panel 10.

[0146] Figure 11 This is a schematic diagram showing the arrangement of the first sub-color filter, the second sub-color filter, the third sub-color filter, and the fourth sub-color filter in a display panel provided in some embodiments of this application.

[0147] In some examples, the photosensitive device 14 may include a fourth sub-device. The color filter layer 16 may include a fourth sub-color filter 164. The fourth sub-color filter 164 may be located in the incident light path of the fourth sub-device.

[0148] In some examples, the light transmission color of the fourth sub-color filter 164 may be different from that of the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163.

[0149] In some examples, the fourth sub-color filter 164 can transmit infrared light. The fourth sub-device can receive the infrared light transmitted through the fourth sub-color filter 164.

[0150] In some examples, the fourth sub-color filter 164 may be configured in the same, similar or identical manner as any one of the first sub-color filter 161, the second sub-color filter 162 and the third sub-color filter 163 in the foregoing embodiments of this application. For details, please refer to the detailed description of the foregoing embodiments of this application. The embodiments of this application will not repeat the details here.

[0151] In some examples of embodiments of this application, a fourth sub-device is provided, and a fourth sub-color filter 164 is provided on the light-incident path of the fourth sub-device. In this way, the fourth sub-color filter 164 can filter out all colors of light except infrared in the ambient light, allowing only infrared light to pass through the fourth sub-color filter 164 and be received by the fourth sub-device. Thus, the photocurrent generated by the first sub-device 144, the second sub-device 145, and the third sub-device 146 can be subtracted from the photocurrent generated by the fourth sub-device due to infrared light, thereby accurately determining the light intensity of each color in the current ambient light, and thus accurately determining the color temperature of the current ambient light. This improves the accuracy of ambient light perception and enhances the display effect and user experience of the display panel 10.

[0152] Figure 12 This is another schematic diagram showing the arrangement of the first sub-color filter, the second sub-color filter, and the third sub-color filter in a display panel provided in some embodiments of this application.

[0153] In some examples, refer to Figure 12 As shown, the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163 can be arranged according to the arrangement of the first light-emitting device 121a, the second light-emitting device 121b, and the third light-emitting device 121c. For example, the transmitted light color of the first sub-color filter 161 can be the same as the emitted light color of the first light-emitting device 121a, and the first sub-color filter 161 can cover the light emission path of the first light-emitting device 121a. The transmitted light color of the second sub-color filter 162 can be the same as the emitted light color of the second light-emitting device 121b, and the second sub-color filter 162 can cover the light emission path of the second light-emitting device 121b. The light-transmitting color of the third sub-color filter 163 can be the same as the light-emitting color of the third light-emitting device 121c. The third sub-color filter 163 can cover the light-emitting path of the third light-emitting device 121c. In this way, each light-emitting device 121 can have a color filter layer 16 with the same light-transmitting color filtering along its light-emitting path. The color filter layer 16 can filter out different colors of light emitted by other light-emitting devices 121, thereby improving the contrast of the display panel 10 and enhancing its display effect.

[0154] Figure 13 This is a schematic diagram showing another arrangement of the first sub-color filter, the second sub-color filter, the third sub-color filter, and the fourth sub-color filter in a display panel provided in some embodiments of this application.

[0155] In some examples, refer to Figure 13As shown, the first sub-color filter 161, the second sub-color filter 162, and the third sub-color filter 163 can be arranged according to the arrangement of the first light-emitting device 121a, the second light-emitting device 121b, and the third light-emitting device 121c. The fourth sub-color filter 164 can cover the light-incident path of the fourth sub-device. That is, the fourth sub-color filter 164 can cover the light-outceasing path of any one of the light-emitting devices 121.

[0156] In some examples, embodiments of this application provide a display device, including the display panel 10 provided in the foregoing embodiments of this application.

[0157] In some examples, the display device can be a laptop computer, mobile phone, wireless device, personal data assistant (PDA), handheld or portable computer, GPS receiver / navigator, camera, MP4 video player, camcorder, game console, watch, clock, calculator, TV monitor, flat panel display, computer monitor, automotive display (e.g., odometer display, etc.), navigator, cockpit controller and / or display, display of camera view (e.g., display of a rearview camera in a vehicle), electronic photograph, electronic billboard or sign, projector, packaging, etc.
