[0064] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0065] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0066] Extended Reality (XR) refers to the use of computer technology to combine the real and virtual worlds, creating an interactive virtual environment that provides an immersive experience. Extended Reality devices offer users a truly immersive experience, placing them within a virtual environment. However, due to this immersive nature, users may experience sleepiness while using Extended Reality devices. Extended Reality devices can include Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) devices.

[0067] Furthermore, because augmented reality (AR) devices are head-mounted displays, their weight and size are limited, resulting in smaller batteries. Battery size significantly impacts battery life. To address this, a camera integrated into the AR device can be used to monitor the user's eye movements and induce sleep. If the user is detected sleeping while using the display, the device can be automatically switched off to conserve power and improve battery life. However, the camera occupies internal space, leading to a larger and more complex AR device, hindering portability and ultimately resulting in a poorer user experience.

[0068] The extended reality device provided in this application embodiment also includes a display panel, which includes an organic light-emitting diode (OLED) display panel, a quantum dot light-emitting diode (QLED) display panel, and a micro light-emitting diode (Micro LED) display panel. The organic light-emitting diode display panel has the characteristics of fast response speed, wide operating temperature range, high contrast, wide viewing angle, ultra-thin panel, and the ability to realize flexible display and light-transmitting display.

[0069] Please refer to Figures 1, 2, and 3. Figure 1 is a structural schematic diagram of a display panel 10 provided in an embodiment of this application. Figure 2 is a cross-sectional structural schematic diagram of the display panel 10 shown in Figure 1 along the A1-A2 position. Figure 3 is a schematic diagram of the optical path of a photosensitive unit 122 monitoring a human eye provided in an embodiment of this application. Figure 1 can be a partial film layer structure schematic diagram of the display area of ​​a display panel 10. In Figure 1, dashed lines are used to represent the outline of the film layer (such as the light-emitting unit 121 and the photosensitive unit 122) located below the filter layer 13, so as to clearly show the structure of the display panel 10. The display panel 10 may include: a substrate 11, a photoelectric structure 12, and a filter layer 13. The photoelectric structure 12 may be located on the substrate 11. The photoelectric structure 12 may include multiple light-emitting units 121 and multiple photosensitive units 122, which are arranged in a direction parallel to the surface of the substrate 11. That is, multiple light-emitting units 121 and multiple photosensitive units 122 may be located in the same layer. The photosensitive unit 122 is used to sense a portion of the light incident on the display panel 10 from the outside, and the multiple light-emitting units 121 are used to emit light and exit the display panel 10.

[0070] As shown in Figure 3, when a person's eyes are open, the eyeball can reflect light, and at least part of the reflected light can enter the display panel 10, and part of the light can illuminate the photosensitive unit 122; when a person's eyes are closed, the eyelids cover the eyeballs, and the eyelids usually do not reflect light; therefore, the amount of light received by the photosensitive unit 122 is different when the person's eyes are open and closed. When the person's eyes are open, the amount of light received by the photosensitive unit 122 is the first amount of light, and when the person's eyes are closed, the amount of light received by the photosensitive unit 122 is the second amount of light, and the first amount of light is greater than the second amount of light.

[0071] Thus, the photosensitive unit 122 can determine whether the user's eyes are open or closed based on the amount of light received (or the light energy received), and perform sleep monitoring on the user using the display panel 10. For example, if the user is detected to be in a closed-eye state for more than 3 minutes, it can be determined that the user is currently asleep.

[0072] The light-emitting unit 121 may include at least one of an organic light-emitting diode (OLED) and a quantum dot light-emitting diode (QLED). Multiple light-emitting units 121 may include light-emitting units 121 for emitting various colors of light. After the display panel 10 is activated, the light-emitting unit 121 can emit light, which can exit the display panel 10 to achieve the function of image display.

[0073] Thus, in this embodiment of the application, by integrating the photosensitive unit 122 into the display panel 10, optical detection of the human eye is achieved through the photosensitive unit 122, and the user's sleep monitoring function is realized by utilizing the optical detection results, thereby enhancing the functionality of the display panel 10, simplifying the structure of the display device, and facilitating the miniaturization of the display device.

[0074] The filter layer 13 can be located on the side of the optoelectronic structure 12 facing away from the substrate 11. The filter layer 13 can include multiple filter units 131 corresponding to multiple light-emitting units 121. The orthographic projection of the light-emitting unit 121 on the substrate 11 lies within the orthographic projection of the corresponding filter unit 131 on the substrate 11. The filter layer 13 can be called a color filter (CF) layer. The multiple filter units 131 can include filter units 131 of various colors. Different colored filter units 131 can be used to transmit different colors of light, and the transmittance of different colored filter units 131 is different.

[0075] For example, if different light-emitting units 121 can emit monochromatic light of different colors, the display panel 10 can be directly displayed in color by multiple light-emitting units 121. In this case, the color of the filter unit 131 in the filter layer 13 can be the same as the light-emitting color of the corresponding light-emitting unit 121. During the display process of the display panel 10, some ambient light can be filtered out by the filter unit 131, reducing the reflection of ambient light inside the display panel 10. This eliminates the need for thick anti-reflection film layers such as circular polarizers, which helps to reduce the thickness of the display panel 10.

[0076] If the light-emitting units 121 emit the same color, such as if all the light-emitting units 121 can emit white light, then the display panel 10 can be displayed in color by using filter units 131 of different colors. In this case, the filter layer 13 can still reduce the reflection of ambient light.

[0077] The plurality of filter units 131 include a first color filter unit 1311 and a second color filter unit 1312, wherein the transmittance of the first color filter unit 1311 is greater than the transmittance of the second color filter unit 1312. The orthographic projection of the photosensitive unit 122 on the substrate 11 overlaps with the orthographic projection of the first color filter unit 1311 on the substrate 11, and the orthographic projection of the photosensitive unit 122 on the substrate 11 is offset from the orthographic projection of the second color filter unit 1312 on the substrate 11. Since the reflected light from the human eyeball first illuminates the filter layer 13 during its incident on the display panel 10, and the filter layer 13 can transmit at least a portion of the reflected light, a portion of the light beam that passes through the filter layer 13 can illuminate the photosensitive unit 122, therefore, by placing the photosensitive unit 122 below the first color filter unit 1311 with higher transmittance, the influence of the filter layer 13 on the amount of light received by the photosensitive unit 122 can be reduced, thereby improving the sensing accuracy and precision of the photosensitive unit 122.

[0078] In summary, this application provides a display panel comprising: a substrate, multiple light-emitting units, multiple photosensitive units, and a filter layer. The photosensitive units are integrated into the display panel to perform optical detection of the human eye, thereby enabling sleep monitoring. This enhances the functionality of the display panel, simplifies the structure of the display device, and facilitates miniaturization. Furthermore, placing the photosensitive units on the side of the first color filter unit with higher transmittance closer to the substrate reduces the influence of the filter layer on the amount of light received by the photosensitive units, improving the sensing accuracy of the photosensitive units.

[0079] Referring to Figure 1, in one optional embodiment, the first color filter unit 1311 includes at least one filter unit 131 of a green filter unit 13G and a red filter unit 13R, and the second color filter unit 1312 includes a blue filter unit 13B; the orthographic projection of the photosensitive unit 122 on the substrate 11 overlaps with at least one of the first projection and the second projection, wherein the first projection is the orthographic projection of the green filter unit 13G on the substrate 11, and the second projection is the orthographic projection of the red filter unit 13R on the substrate 11.

[0080] For example, a plurality of light-emitting units 121 are arranged in an array along a direction parallel to the surface of the substrate 11. The plurality of light-emitting units 121 include a red light-emitting unit for emitting red light, a blue light-emitting unit for emitting blue light, and a green light-emitting unit for emitting green light.

[0081] Alternatively, a plurality of light-emitting units 121 are arranged in an array along a direction parallel to the surface of the substrate 11, and the plurality of light-emitting units 121 include white light-emitting units for emitting white light.

[0082] Multiple filter units 131 in the filter layer 13 are also arranged in an array along a direction parallel to the surface of the substrate 11, and adjacent filter units 131 can be connected or in contact. Each filter unit 131 has a unique color, so that each filter unit 131 can only transmit blue light, red light, green light or other monochromatic light. Through the light-emitting unit 121 and the filter units 131, light of various colors can be formed, and the display panel 10 can then display images.

[0083] For example, the filter layer 13 may include a red filter unit 13R, a green filter unit 13G, and a blue filter unit 13B. The red filter unit 13R corresponds to a red light-emitting unit and transmits red light; the green filter unit 13G corresponds to a green light-emitting unit and transmits green light; and the blue filter unit 13B corresponds to a blue light-emitting unit and transmits blue light. Alternatively, the red filter unit 13R, green filter unit 13G, and blue filter unit 13B may each correspond to a plurality of white light-emitting units.

[0084] The materials of the different colored filter units 131 are different, and therefore the transmittance of the different colored filter units 131 is also different. For example, the transmittance of the green filter unit 13G can be greater than that of the red filter unit 13R, and the transmittance of the red filter unit 13R can be greater than that of the blue filter unit 13B. The transmittance range of the green filter unit 13G can be 70% to 90%, such as 70%, 75%, 78%, 80%, or 85%; the transmittance range of the red filter unit 13R can be 30% to 60%, such as 35%, 40%, 42%, 50%, or 55%; and the transmittance range of the blue filter unit 13B can be 10% to 40%, such as 10%, 18%, 26%, 37%, or 38%. It should be noted that the above values ​​can include endpoint values.

[0085] Thus, by placing the photosensitive unit 122 on the side of the red filter unit 13R and the green filter unit 13G with higher transmittance closer to the substrate 11, the photosensitive unit 122 can receive more light reflected from the eyeball, which can reduce the influence of the filter layer 13 on the amount of light received by the photosensitive unit 122, thereby improving the sensing accuracy and precision of the photosensitive unit 122.

[0086] Please refer to Figures 4 and 5. Figure 4 is a schematic diagram of another display panel 10 provided in an embodiment of this application, and Figure 5 is a schematic diagram of another display panel 10 provided in an embodiment of this application. In Figures 4 and 5, dashed lines are used to represent the outlines of the film layers (such as light-emitting unit 121 and photosensitive unit 122) located below the filter layer 13, so as to clearly show the structure of the display panel 10. In an optional embodiment, the orthographic projection of the photosensitive unit 122 on the substrate 11 overlaps with the boundary line of the first projection and the second projection, and the shortest distance L1 between the center of the orthographic projection of the photosensitive unit 122 on the substrate 11 and the boundary line of the first projection and the second projection is less than or equal to 10 micrometers. The first projection is the orthographic projection of the green filter unit 13G on the substrate 11, and the second projection is the orthographic projection of the red filter unit 13R on the substrate 11.

[0087] The photosensitive unit 122 can be located on the side of the substrate 11 near the connection between adjacent green filter unit 13G and red filter unit 13R. The photosensitive unit 122 can be located between adjacent green light-emitting units and red light-emitting units, and the center of the photosensitive unit 122 can coincide with the connection between the green filter unit 13G and red filter unit 13R. This can reduce the impact on the light-emitting unit 121 when the photosensitive unit 122 is integrated into the display panel 10.

[0088] For example, the shortest distance L1 between the center of the orthographic projection of the photosensitive unit 122 on the substrate 11 and the boundary line between the first projection and the second projection can be 0 micrometers, 2 micrometers, 6 micrometers, 7 micrometers, or 10 micrometers. The center of the orthographic projection of the photosensitive unit 122 on the substrate 11 is the geometric center.

[0089] In one alternative embodiment, the orthographic projection of the photosensitive unit 122 onto the substrate 11 is rectangular, and the axis of symmetry of the orthographic projection of this rectangle may coincide with the boundary line between the first projection and the second projection. The orthographic projection of the filter unit 131 onto the substrate 11 may be hexagonal, rectangular, or square.

[0090] Please refer to Figures 6 and 7. Figure 6 is a schematic diagram of another display panel 10 provided in an embodiment of this application, and Figure 7 is a schematic diagram of another display panel 10 provided in an embodiment of this application. In Figures 6 and 7, dashed lines are used to represent the outlines of the film layers (such as light-emitting unit 121 and photosensitive unit 122) located below the filter layer 13, so as to clearly show the structure of the display panel 10. In an optional embodiment, the orthographic projection of the photosensitive unit 122 on the substrate 11 is located in the first projection, and the shortest distance L2 between the edge of the orthographic projection of the photosensitive unit 122 on the substrate 11 and the edge of the first projection is less than or equal to 10 micrometers. The first projection is the orthographic projection of the green filter unit 13G on the substrate 11. Since the transmittance of the green filter unit 13G is higher than that of the red filter unit 13R and the blue filter unit 13B, the photosensitive unit 122 can also be disposed only on the side of the green light unit close to the substrate 11 to further increase the amount of reflected light irradiated onto the photosensitive unit 122.

[0091] Furthermore, the orthographic projection of the photosensitive unit 122 on the substrate 11 can be as close as possible to the boundary line between the first projection and the second projection to avoid affecting the light-emitting unit 121. For example, the shortest distance L2 between the edge of the orthographic projection of the photosensitive unit 122 on the substrate 11 and the edge of the first projection can be 0 micrometers, 2 micrometers, 6 micrometers, 7 micrometers or 10 micrometers.

[0092] Referring to Figures 1 and 2, in an optional embodiment, the display panel 10 may further include a pixel definition layer 14 (PDL). The pixel definition layer 14 may be located on the substrate 11 and may have a plurality of first openings 141 and a plurality of second openings 142. The plurality of first openings 141 correspond one-to-one with a plurality of filter units 131, and the orthographic projection of the first opening 141 on the substrate 21 lies in the orthographic projection of the corresponding filter unit 131 on the substrate 21.

[0093] The first opening 141 can be referred to as a pixel opening. Multiple first openings 141 and multiple second openings 142 can be arranged in an array. Each first opening 141 and each second opening 142 can penetrate the pixel defining layer 14 along its thickness direction. The pixel defining layer 14 may include a first gap between adjacent first openings 141 and second openings 142, and a second gap between two adjacent first openings 141. The area on the pixel defining layer 14 other than the first openings 141 and second openings 142 is a continuous structure.

[0094] The light-emitting unit 121 may include a light-emitting functional layer 1211, at least a portion of which is located in the first opening 141, and the photosensitive unit 122 is located in the second opening 142.

[0095] Optionally, the light-emitting functional layer 1211 includes a stacked hole transport layer, a light-emitting layer, and an electron transport layer. Each light-emitting functional layer 1211 in each first opening 141 corresponds to a sub-pixel. Light-emitting functional layers 1211 in different first openings 141 can emit light of the same color or different colors. Multiple sub-pixels corresponding to multiple first openings 141 can include various sub-pixels, such as a red sub-pixel R, a blue pixel B, and a green pixel G. Multiple sub-pixels can also include sub-pixels of other colors; no specific limitation is made here. For example, a second opening 142 can be located between adjacent sub-pixels, and at least one second opening 142 is provided between two adjacent first openings 141.

[0096] Multiple light-emitting units 121 correspond one-to-one with multiple pixel openings. The light-emitting unit 121 may also include an anode 1212 and a cathode located on both sides of the light-emitting functional layer 1211 along a direction perpendicular to the substrate 11. The anode 1212 is located between the light-emitting functional layer 1211 and the substrate 11, and the cathode is located on the side of the light-emitting functional layer 1211 facing away from the substrate 1111.

[0097] The pixel openings in the pixel defining layer 14 can be used to expose the anode 1212, allowing the anode 1212 to contact the light-emitting material, thereby defining the shape of the pixel. The pixel defining layer can be used to define the shape of the light-emitting unit 121. The shape of the light-emitting unit 121 presented on the display panel 10 is approximately the shape of the pixel opening, which can be circular, elliptical, hexagonal, rectangular, etc. This embodiment does not limit the shape of the pixel opening. The material of the pixel defining layer 14 can include inorganic insulating materials, such as silicon oxide or silicon nitride.

[0098] Referring to Figures 1, 5, and 6, in one optional embodiment, the plurality of filter units 131 may include a green filter unit 13G, a red filter unit 13R, and a blue filter unit 13B, and the plurality of first openings 141 include a plurality of pixel opening groups 141a; the pixel opening group 141a may include a first pixel opening G corresponding to the green filter unit 13G, a second pixel opening R corresponding to the red filter unit 13R, and a third pixel opening B corresponding to the blue filter unit 13B; the plurality of pixel opening groups 141a correspond one-to-one with the plurality of photosensitive units, and the photosensitive units are located between the first pixel opening G and the second pixel opening R in the corresponding pixel opening group 141a.

[0099] Figures 1, 5, and 6 respectively illustrate two exemplary arrangements of the first pixel opening G, the second pixel opening R, and the third pixel opening B. In Figure 1, the first opening 141 (first pixel opening G, second pixel opening R, and third pixel opening B) corresponding to the green filter unit 13G, the red filter unit 13R, and the blue filter unit 13B can all be hexagonal, and the opening sizes of the first pixel opening G, the second pixel opening R, and the third pixel opening B are the same, which can be the opening area. A photosensitive unit 122 corresponding to a pixel opening group 141a can be located between the first pixel opening G and the second pixel opening R in the pixel opening group 141a.

[0100] In Figure 5, the first pixel opening G, the second pixel opening R, and the third pixel opening B can all be quadrilaterals. The opening size of the third pixel opening B is larger than the opening size of the second pixel opening R, and also larger than the opening size of the first pixel opening G. In Figure 6, the first pixel opening G, the second pixel opening R, and the third pixel opening B can all be quadrilaterals. The opening size of the third pixel opening B is larger than the opening size of the second pixel opening R, and the opening size of the second pixel opening R is larger than the opening size of the first pixel opening G.

[0101] It should be noted that the first pixel opening G, the second pixel opening R, and the third pixel opening B can also be arranged in other ways. For example, the first pixel opening G, the second pixel opening R, and the third pixel opening B can be arranged in a straight line.

[0102] Please refer to Figures 8 and 9. Figure 8 is a schematic diagram of the structure of another display panel 10 provided in an embodiment of this application, and Figure 9 is a schematic diagram of the structure of another display panel 10 provided in an embodiment of this application. In Figures 8 and 9, dashed lines are used to represent the outlines of the film layers (such as light-emitting units 121 and photosensitive units 122) located below the filter layer 13, so as to clearly show the structure of the display panel 10. In an optional embodiment, the plurality of filter units 131 may include a green filter unit 13G, a red filter unit 13R, and a blue filter unit 13B. The first opening 141 includes a plurality of pixel opening groups 141a; the pixel opening group 141a may include a first pixel opening G corresponding to the green filter unit 13G, a second pixel opening R corresponding to the red filter unit 13R, and a third pixel opening B corresponding to the blue filter unit 13B; at least one pixel opening group 141a in the plurality of pixel opening groups 141a corresponds to a plurality of photosensitive units 122, and the plurality of photosensitive units 122 corresponding to a pixel opening group 141a may be arranged around the first pixel opening G in the corresponding pixel opening group 141a.

[0103] The ratio of the plurality of pixel aperture groups 141a and the plurality of photosensitive units 122 in the display panel 10 can be 1:2, that is, one pixel aperture group 141a can correspond to two photosensitive units 122, and the two photosensitive units 122 can be arranged around the first pixel opening G in the corresponding pixel aperture group 141a, that is, the two photosensitive units 122 can be located on both sides of the first pixel opening G. Alternatively, the ratio of the plurality of pixel aperture groups 141a and the plurality of photosensitive units 122 in the display panel 10 can be 1:3. In an exemplary embodiment, the plurality of photosensitive units 122 corresponding to one pixel aperture group 141a can be evenly arranged around the first pixel opening G in the corresponding pixel aperture group 141a.

[0104] Please refer to Figure 10, which is a schematic diagram of another display panel 10 provided in an embodiment of this application. In an optional embodiment, at least a portion of the edge of the photosensitive unit 122 located in the second opening 142 has a target gap L3 between it and the edge of the pixel defining layer 14; a portion of the light-emitting functional layer 1211 extends into the second opening 142, and at least a portion of the light-emitting functional layer 1211 located in the second opening 142 is broken at the edge of the photosensitive unit 122.

[0105] The second opening 142 of the pixel defining layer 14 is configured to expose at least a portion of the edge of the photosensitive unit 122, such that at least a portion of the light-emitting functional layer 1211 extending into the second opening 142 is truncated by the edge of the isolated photosensitive unit 122. Exemplarily, the light-emitting functional layer 1211 includes at least one common layer located within the first opening 141 and extending along the pixel defining layer 14 to the edge of the photosensitive unit 122 within the second opening 142. This common layer may be an electron transport layer. The light-emitting functional layer 1211 may also include other film layers with different functions and extending locations. For example, other film layers in the light-emitting functional layer 1211 may be located within the first opening 141 and extend to a first interval around the first opening 141 (not extending into the second opening 142), or they may be located within the first opening 141 and extend along the first interval to the edge of the photosensitive unit 122 within the second opening 142; no specific limitation is made here.

[0106] The photosensitive unit 122 has a photosensitive surface, and the second opening 142 of the pixel defining layer 14 is also configured to expose the photosensitive surface of the photosensitive unit 122, so that the photosensitive surface can receive light reflected from the eyeball onto the display panel 10. In this way, the photosensitive unit 122 can be reused as a partition structure to further simplify the structure of the display panel 10, reduce the thickness of the display panel 10, and reduce the manufacturing difficulty of the display panel 10.

[0107] For example, in the direction parallel to the substrate 11, the width of the target gap L3 ranges from 1 micrometer to 3 micrometers. In this way, it can be ensured that at least a portion of the edges of the isolation structure can effectively block at least a portion of the light-emitting functional layer 1211, and the opening size of the second opening 142 is not too large and can affect the first opening 141.

[0108] Please refer to Figure 11, which is a schematic diagram of another display panel 10 provided in an embodiment of this application. In the direction perpendicular to the surface of the substrate 11, the height of the photosensitive unit 122 located in the second opening 142 is greater than the height of the pixel defining layer 14; a portion of the light-emitting functional layer 1211 extends to the second opening 142, and at least a portion of the light-emitting functional layer 1211 located at the second opening 142 is interrupted at the edge of the photosensitive unit 122. Thus, by having at least a portion of the light-emitting functional layer 1211 extending to the second opening 142 truncated by the edge of the isolation structure photosensitive unit 122, the photosensitive unit 122 can be reused as an isolation structure to further simplify the structure of the display panel 10. It is understood that the extension of a portion of the light-emitting functional layer 1211 to the second opening 142 means that the orthographic projection of a portion of the light-emitting functional layer 1211 on the substrate 11 overlaps with the orthographic projection of the second opening 142 on the substrate 11.

[0109] Please refer to Figure 12, which is a schematic diagram of another display panel structure provided in an embodiment of this application. The display panel 10 may further include a driving circuit 19 located on a substrate 11. The driving circuit 19 is electrically connected to the anode 1212 of the light-emitting unit 121, thereby providing an anode voltage to the anode 1212. The cathode 1213 can provide a cathode voltage to the multiple pixel structures on the display panel 10.

[0110] In one exemplary embodiment, the cathode can be a transparent electrode, for example, made of a transparent conductive oxide material such as indium tin oxide (ITO) or indium zinc oxide (IZO), which can make the display panel 1020 have higher transmittance. The anode 1212 can be made of at least one of copper (Cu), silver (Ag), and aluminum (Al).

[0111] The photosensitive unit 122 may further include a first electrode and a second electrode electrically connected to the photosensitive material layer. The first electrode may be located on the side of the photosensitive material closer to the substrate and may be connected to the driving circuit 19. The second electrode may be located on the side of the photosensitive material away from the substrate, or the second electrode and the photosensitive material may be in the same layer. The principle for setting the first and second electrodes is to connect the photosensitive material layer and the driving circuit 19 into a conductive loop. The specific placement of the first and second electrodes is not limited in this embodiment. The driving circuit can receive different photosensitive signals generated by the photosensitive unit 122 under different lighting conditions. The material of the photosensitive material layer may include amorphous silicon or low-temperature polycrystalline silicon.

[0112] The driving circuit 19 may include a driving transistor. The active layer of the driving transistor may be made of amorphous silicon (a-Si), low-temperature poly-silicon (LTPS or p-Si), or metal oxide. The driving transistor may be a low-temperature polycrystalline silicon thin-film transistor or a single-crystal silicon thin-film transistor.

[0113] Optionally, the photosensitive material layer in the photosensitive unit 122 can be reused as a partition structure, or the stacked structure formed by the first electrode, the photosensitive material layer and the second electrode in the photosensitive unit 122 can be reused as a partition structure.

[0114] Please refer to Figures 13, 14, and 15. Figure 13 is a schematic diagram of another display panel 10 provided in an embodiment of this application. Figure 14 is a cross-sectional schematic diagram of the display panel 10 shown in Figure 13 along the B1-B2 position. Figure 15 is a schematic diagram of the optical path of a photosensitive unit 122 monitoring a human eye provided in an embodiment of this application. Figure 13 can be a schematic diagram of a partial film layer structure of the display area of ​​a display panel 10. In Figure 13, dashed lines are used to represent the outline of the film layer (such as the filter layer 13, the light-emitting unit 121, and the photosensitive unit 122) located under the first protrusion structure 16, so as to clearly show the structure of the display panel 10. In an optional embodiment, the display panel 10 may further include a first light-transmitting layer 15, and a plurality of first protrusion structures 16 corresponding to a plurality of photosensitive units 122. The first protrusion structure 16 is located on the side of the photosensitive unit 122 facing away from the substrate 11, and the orthographic projection of the first protrusion structure 16 on the substrate 11 overlaps with the orthographic projection of the corresponding photosensitive unit 122 on the substrate 11. The first light-transmitting layer 15 is located on the side of the plurality of first protrusions 16 away from the substrate 11, and the first light-transmitting layer 15 covers the first protrusions 16. The refractive index of the first light-transmitting layer 15 is less than the refractive index of the first protrusions 16.

[0115] The dimension of the first protrusion structure 16 on the side closer to the substrate 11 is larger than the dimension of the first protrusion structure 16 on the side farther from the substrate 11. The orthographic projection of the first protrusion structure 16 on the substrate 11 does not overlap with the orthographic projection of the light-emitting unit 121 on the substrate 11.

[0116] Please refer to Figures 15, 16, and 17. Figure 16 is a schematic diagram of the optical path of another display panel 10 provided in this application embodiment, and Figure 17 is a schematic diagram of the optical path of another display panel 10 provided in this application embodiment. The light emitted by the light-emitting unit 121 may include at least a first light s1. The first light s1 can be emitted from the light-emitting unit 121 and enter the human eye. The human eye can reflect part of the received first light s1 back to the display panel 10. The light reflected by the human eye can be a second light s2. The second light s2 can enter the first light-transmitting layer 15 and then pass through the first light-transmitting layer 15 to illuminate the surface of the first protruding structure 16. The surface of the first protruding structure 16 is the interface between the first light-transmitting layer 15 and the first protruding structure 16. Since the refractive index of the first light-transmitting layer 15 is less than the refractive index of the first protruding structure 16, the second light s2 is in a state of moving from a less dense medium to a denser medium. Based on the principle of light refraction, a portion of the second light s2 will be deflected at the surface of the first protruding structure 16 and will be directed toward the area where the photosensitive unit 122 is located. That is, when the second light s2 obliquely enters the first protruding structure 16 from the first light-transmitting layer 15, the refraction angle α1 is smaller than the incident angle α2. In this way, the first protruding structure 16 gathers the light that might otherwise not be able to reach the photosensitive unit 122 and guides it to the photosensitive surface of the photosensitive unit 122, thereby increasing the amount of light reflected by the human eye from the second light s2 that reaches the photosensitive unit 122, thereby improving the sensing accuracy and precision of the photosensitive unit 122.

[0117] It should be noted that, in order to clearly show the direction of the light path that the light shines on the photosensitive unit 122, only a portion of the light path is shown in Figures 15, 16 and 17. This portion of the light path does not completely represent the amount of light emitted by the light-emitting unit 121 from the direction shown in the figure, nor does it completely represent the amount of light reflected by the human eye.

[0118] For example, the first protrusion structure 16 may be hemispherical in shape, and the focal length of the first protrusion structure 16 satisfies the following formula:

[0119] Where f is the focal length of the first protrusion structure 16, r is the radius of curvature of the first protrusion structure 16, n1 is the refractive index of the first light-transmitting layer 15, and n2 is the refractive index of the first protrusion structure 16.

[0120] Please refer to Figure 18, which is a schematic diagram of another display panel 10 provided in an embodiment of this application. In an optional embodiment, the orthographic projection of the photosensitive unit 122 on the substrate 11 can be located within the orthographic projection of the first protrusion structure 16 on the substrate 11. Optionally, the orthographic projection of the first protrusion structure 16 on the substrate 11 is circular or elliptical. It is understood that the orthographic projection of the photosensitive unit 122 on the substrate 11 shown in Figure 18 of this embodiment can be the orthographic projection of the light-emitting material layer in the photosensitive unit 122 on the substrate.

[0121] When the orthographic projection of the first protrusion structure 16 on the substrate 11 is circular, the orthographic projection of the photosensitive unit 122 corresponding to the first protrusion structure 16 on the substrate 11 can be a regular polygon, such as a square or a regular hexagon. The first ratio of the diameter of the orthographic projection of the first protrusion structure 16 on the substrate 11 to the side length of the orthographic projection of the corresponding photosensitive unit 122 on the substrate 11 is in the range of 0.5 to 1.5. For example, the first ratio can be 0.8, 1, 1.2, 1.4 or 1.5.

[0122] When the orthographic projection of the first protrusion structure 16 on the substrate 11 is elliptical, the orthographic projection of the photosensitive unit 122 corresponding to the first protrusion structure 16 on the substrate 11 can be rectangular or a symmetrical polygon. The second ratio of the major axis of the orthographic projection of the first protrusion structure 16 on the substrate 11 to the long side of the orthographic projection of the corresponding photosensitive unit 122 on the substrate 11 ranges from 0.5 to 1.5. For example, the second ratio can be 0.8, 1, 1.2, 1.4, or 1.5. The third ratio of the minor axis of the orthographic projection of the first protrusion structure 16 on the substrate 11 to the short side of the orthographic projection of the corresponding photosensitive unit 122 on the substrate 11 ranges from 0.5 to 1.5. For example, the third ratio can be 0.8, 1, 1.2, 1.4, or 1.5.

[0123] Please refer to Figures 19, 20, and 21. Figure 19 is a schematic diagram of another display panel 10 provided in an embodiment of this application. Figure 20 is a schematic diagram of the cross-sectional structure of the display panel 10 shown in Figure 19 along the C1-C2 position. Figure 21 is a schematic diagram of the optical path of a photosensitive unit 122 monitoring a human eye provided in an embodiment of this application. Figure 19 can be a schematic diagram of a partial film layer structure of the display area of ​​a display panel 10. In Figure 19, dashed lines are used to represent the outline of the film layer (such as the filter layer 13, the light-emitting unit 121, and the photosensitive unit 122) located under the first protrusion structure 16 and the second protrusion structure 17, so as to clearly show the structure of the display panel 10. In an optional embodiment, the display panel 10 may further include a plurality of second protrusion structures 17 corresponding to a plurality of light-emitting units 121. The orthographic projection of the light-emitting unit 121 on the substrate 11 overlaps with the orthographic projection of the corresponding second protrusion structure 17 on the substrate 11. The second protrusion structure 17 and the first protrusion structure 16 are in the same layer, and the first protrusion structure 16 is located between two adjacent second protrusion structures 17. A first light-transmitting layer 15 covers the second protrusion structure 17, and the refractive index of the first light-transmitting layer 15 is less than the refractive index of the second protrusion structure 17. The orthographic projection of the first opening 141 corresponding to the light-emitting unit 121 on the substrate 21 may be located within the orthographic projection of the second protrusion structure 17 corresponding to the light-emitting unit 121 on the substrate.

[0124] The light emitted by the light-emitting unit 121 can include at least a first ray s1. The first ray s1 can exit from the light-emitting unit 121 and enter the second protruding structure 17, then pass through the second protruding structure 17 and illuminate the interface between the second protruding structure 17 and the first light-transmitting layer 15. Since the refractive index of the first light-transmitting layer 15 is less than the refractive index of the second protruding structure 17, the first ray s1 is in a state of moving from an optically denser medium to an optically less dense medium. Based on the principle of light refraction, a portion of the first ray s1 will be deflected at the interface between the second protruding structure 17 and the first light-transmitting layer 15. The light emitted from the light-emitting unit 121 is directed towards the area directly opposite the display panel 10. In this way, the second protrusion structure 17 guides the light that might otherwise not reach the human eye to the human eye. The second protrusion structure 17 can reduce the light emission angle of at least part of the light emitted from the light-emitting unit 121 (such as the first light s1), thereby improving the light emission efficiency of the front side of the display panel 10, increasing the amount of light emitted from the light-emitting unit 121 that reaches the human eye, and also increasing the amount of light reflected by the second light s2 that reaches the photosensitive unit 122, thereby improving the sensing accuracy and precision of the photosensitive unit 122.

[0125] Referring to Figure 20, in one optional embodiment, the shortest distance L4 between the first protrusion structure 16 and the adjacent second protrusion structure 17 ranges from 0 micrometers to 2 micrometers. For example, this shortest distance L4 can be 0 micrometers, 0.5 micrometers, 0.8 micrometers, 1 micrometer, 1.8 micrometers, or 2 micrometers. That is, the first protrusion structure 16 and the second protrusion structure 17 can be an integral structure.

[0126] Optionally, the height h1 of the first protrusion structure 16 in the direction perpendicular to the surface of the substrate 11 ranges from 0.5 micrometers to 3 micrometers, and the height h2 of the second protrusion structure 17 in the direction perpendicular to the substrate 11 ranges from 1 micrometer to 4 micrometers. For example, the height h1 of the first protrusion structure 16 in the direction perpendicular to the surface of the substrate 11 can be 0.5 micrometers, 0.6 micrometers, 0.8 micrometers, 1 micrometer, 1.5 micrometers, 2 micrometers, 2.6 micrometers, or 3 micrometers. The height h2 of the second protrusion structure 17 in the direction perpendicular to the surface of the substrate 11 can be 1 micrometer, 1.5 micrometers, 2.2 micrometers, 2.6 micrometers, 3.1 micrometers, 3.5 micrometers, 3.8 micrometers, or 4 micrometers.

[0127] In an optional embodiment, the materials of the first protrusion structure 16 and the second protrusion structure 17 may include optically clear adhesive (OCA) and zirconium oxide (ZrO2). The refractive index of the first protrusion structure 16 and the refractive index of the second protrusion structure 17 may range from 1.55 to 2.1. For example, the refractive indices of the first protrusion structure 16 and the second protrusion structure 17 are 1.55, 1.56, 1.61, 1.65, 1.7, 1.75, 1.8, 1.85, 1.91, 1.95, or 2.1. The material of the first light-transmitting layer 15 may include optical adhesive. The refractive index of the first light-transmitting layer 15 may range from 1.4 to 1.55. For example, the refractive index of the first light-transmitting layer 15 is 1.4, 1.43, 1.46, 1.45, 1.5, 1.52, or 1.55.

[0128] In an alternative embodiment, referring to FIG20, the display panel may further include an encapsulation layer 181, a first planarization layer 182, and a second planarization layer 183.

[0129] Please refer to Figure 21, which is a schematic diagram of another display panel structure provided in an embodiment of this application. The display panel 10 may further include a driving circuit 19 located on the substrate 11. The driving circuit 19 is electrically connected to the anode 1212 of the light-emitting unit 121, thereby providing an anode voltage to the anode 1212. The cathode 1213 can provide a cathode voltage to the multiple pixel structures on the display panel 10.

[0130] The photosensitive unit 122 may also include a first electrode and a second electrode electrically connected to the photosensitive material layer. The first electrode may be located on the side of the photosensitive material close to the substrate and may be connected to the driving circuit 19. The second electrode may be located on the side of the photosensitive material away from the substrate, or the second electrode and the photosensitive material may be in the same layer. The principle for setting the first electrode and the second electrode is to be able to connect the photosensitive material layer and the driving circuit 19 into a conductive loop. The specific setting position of the first electrode and the second electrode is not limited in this embodiment. The driving circuit can receive different photosensitive signals generated by the photosensitive unit 122 under different lighting conditions.

[0131] In one exemplary embodiment, the cathode can be a transparent electrode, for example, made of a transparent conductive oxide material such as indium tin oxide (ITO) or indium zinc oxide (IZO), which can make the display panel 1020 have higher transmittance. The anode 1212 can be made of at least one of copper (Cu), silver (Ag), and aluminum (Al).

[0132] The driving circuit 19 may include a driving transistor. The active layer of the driving transistor may be made of amorphous silicon (a-Si), low-temperature poly-silicon (LTPS or p-Si), or metal oxide. The driving transistor may be a low-temperature polycrystalline silicon thin-film transistor or a single-crystal silicon thin-film transistor.

[0133] In summary, this application provides a display panel comprising: a substrate, multiple light-emitting units, multiple photosensitive units, and a filter layer. The photosensitive units are integrated into the display panel to perform optical detection of the human eye, thereby enabling sleep monitoring. This enhances the functionality of the display panel, simplifies the structure of the display device, and facilitates miniaturization. Furthermore, placing the photosensitive units on the side of the first color filter unit with higher transmittance closer to the substrate reduces the influence of the filter layer on the amount of light received by the photosensitive units, improving the sensing accuracy of the photosensitive units.

[0134] This application also provides a display device, which includes a power supply component and a display panel. The power supply component is used to supply power to the display panel. The display panel can be any of the display panels described in the above embodiments.

[0136] In this application, the term "at least one of A and B" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, "at least one of A and B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0137] It should be noted that the dimensions of layers and regions may be exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers.
