DETAILED DESCRIPTION
[0033] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale.
[0034] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of an icon to another component, these terms are used in this specification only for convenience, for example, according to the directions in the examples in the drawings. It can be understood that if the device of the icon is flipped so that it is upside down, the component described as "upper" will become the component described as "lower". When a structure is "on" another structure, it may mean that a structure is integrally formed on another structure, or that a structure is "directly" disposed on another structure, or that a structure is "indirectly" disposed on another structure through another structure.
[0035] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "comprising" and "having" are used to mean an open inclusion and mean that there may be additional elements / components / etc. in addition to the listed elements / components / etc.; the terms "first", "second", "third", etc. are used only as labels and are not a limitation on the quantity of their objects.
[0036] In order to make the display panel thinner and consume less power, the polarizer is removed, and a color film layer is provided on the side of the encapsulation layer (COE, Color On Encapsulation) away from the substrate. The color film layer filters the light emitted by the light-emitting layer. The color film layer includes a light-shielding layer, and a second light-transmitting opening is provided on the light-shielding layer. A light sensor is provided on the side of the substrate away from the second source-drain conductive layer. Ambient light is incident on the light sensor through the second light-transmitting opening and the first light-transmitting opening in sequence, and the light sensor collects the external light intensity to adjust the brightness of the screen itself in real time. A heat sensor can also be provided on the side of the substrate away from the second source-drain conductive layer, and the temperature of the screen itself is adjusted through the heat sensor. A pressure-sensitive sensor can also be provided on the side of the substrate away from the second source-drain conductive layer, and the touch sensitivity of the screen is adjusted through the pressure-sensitive sensor.
[0037] In order to further improve the rationality of the screen brightness condition, the concept of the field of view of the light sensor 11 is proposed, and the field of view ability of the display panel is characterized by testing the half-attenuation angle. Figure 1 For the test fixture 100 of the half-attenuation angle, its test method is as follows: The light source moves with the angle above. When the light source is directly above the display device 200, record the ambient light brightness collected by the light sensor 11 as A0. Rotate the angle of the light source clockwise or counterclockwise until the brightness collected by the light sensor 11 becomes 0.5*A0, and record the angle θ corresponding to the light source at this time. This angle is the half-attenuation angle in the second direction. Rotate the display device 200 by 90 degrees, and test the half-attenuation angle in the first direction according to the above method.
[0038] Generally, the larger the half-life angle is, the better. It indicates that in the same environment, when the display device 200 rotates by a certain angle, the screen brightness will not change, providing a better experience. For example, Figure 2 As shown, during the test of the display device 200 with a color film layer, it is found that there is a large difference in the half-life angles of the display device 200 in the first direction and the second direction. This means that under the same ambient light conditions, when the user uses the display device 200 horizontally and vertically, the brightness of its screen will change significantly. When the display device 200 is rotated back and forth, the brightness of the screen switches back and forth, giving people a feeling of screen flickering and affecting the experience.
[0039] For example, Figure 2 As shown, when the ambient light is incident on the light sensor 11 through the second light-transmitting opening 71 and the first light-transmitting opening 61 in sequence, at different test angles, the display panel has different forward brightnesses X+ along the positive direction of the first direction x and different reverse brightnesses X- along the reverse direction of the first direction x. At different test angles, the display panel has different forward brightnesses Y+ along the positive direction of the second direction y and different reverse brightnesses Y- along the reverse direction of the second direction y. The brightness changes collected by the light sensor 11 in the first direction x and the second direction y at different test angles are shown in Table 1.
[0040] Table 1 Brightness changes collected by the light sensor 11 in the first direction x and the second direction y at different test angles
[0041] Test Angle Y+ Y- X+ X- 0 415 415 414 414 5 419 419 418 394 10 406 416 405 405 15 383 391 394 375 20 348 338 379 339 25 272 250 344 278 30 197 179 296 237 35 245 172 40 195 Half-life Angle 28° 27° 37° 32°
[0042] Analyzing the reasons for the difference in the half-life angles between the first direction and the second direction, there are mainly the following two aspects:
[0043] Generally, the shape of the second light-transmitting opening 71 is rectangular. Therefore, the size of the second light-transmitting opening 71 in the first direction is different from that in the second direction, resulting in inconsistent light incident amounts in the first direction and the second direction. The larger the size of the second light-transmitting opening 71 in the first direction or the second direction, the more beneficial it is to the half-life angle. For the rectangular second light-transmitting opening 71, the size of the second light-transmitting opening 71 in the first direction is larger than that in the second direction. There are differences in the reflection of the ambient light by the driving circuit layer in the first direction and the second direction. The optical paths of the light incident from the second light-transmitting opening 71 are different when transmitting in the first direction and the second direction, resulting in different intensities reaching the light sensor 11. It should be noted that the first direction x is the row direction of the display panel, and the second direction y is the column direction of the display panel.
[0044] For example, Figure 3As shown in the figure, in order to increase the pixel density of the display panel, data lines 21 are usually disposed on the first source-drain conductive layer 2. A connection portion 214 is provided on the data lines 21. A second source-drain conductive layer 4 is provided on a side of the first source-drain conductive layer 2 close to the substrate 1. A first conductive portion 43 is provided on the second source-drain conductive layer 4. The connection portion 214 is connected to the first conductive portion 43 through a second via 32 on the second planarization layer.
[0045] Since the distance between the connection portion 214 and the lower-layer traces is relatively large, the first conductive portion 43 can be connected to a third source-drain conductive layer closer to the substrate 1 than the second source-drain conductive layer 4. The third source-drain conductive layer ( Figure 3 not shown in the figure) is usually provided with a source or drain of a transistor, so as to input or output a data signal to or from the corresponding transistor, which can reduce the parasitic capacitance of the data lines 21 and avoid data signal delay caused by excessive parasitic capacitance. In the case where the requirement for pixel density is not high or the number of traces is relatively small, the display panel may only include the first source-drain conductive layer 2 and the second source-drain conductive layer 4, that is, a source or drain of a transistor is provided on the second source-drain conductive layer 4.
[0046] As Figure 3 shown in the figure, ambient light at a small angle can sequentially pass through the second light-transmitting opening 71 and the first light-transmitting opening 61 and directly enter the light sensor 11 in the middle. Ambient light at a large angle enters the first source-drain conductive layer 2 and the second source-drain conductive layer 4 located on both sides of the first light-transmitting opening 61 in the first direction x. After the first source-drain conductive layer 2 and the second source-drain conductive layer 4 on both sides of the first light-transmitting opening 61 reflect and absorb the ambient light at a large angle, the light enters the light sensor 11 in the middle. In the second direction y, the first source-drain conductive layer 2 and the second source-drain conductive layer 4 are not provided on both sides of the first light-transmitting opening 61, so as not to affect the ambient light in the second direction y. The ambient light at a small angle and the ambient light at a large angle in the second direction y can directly enter the light sensor 11.
[0047] Based on this, an embodiment of the present invention provides a display module. As Figures 4 to 10As shown, the display panel may include a substrate 1, a driving circuit layer, a pixel definition layer 6, and a light-shielding layer 7. The driving circuit layer includes a first source-drain conductive layer 2 and a second source-drain conductive layer 4. The first source-drain conductive layer 2 is disposed on one side of the substrate 1, and the second source-drain conductive layer 4 is disposed on the side away from the substrate 1 or on the side close to the substrate 1 of the first source-drain conductive layer 2; the pixel definition layer 6 is disposed on the side away from the substrate 1 of the driving circuit layer, and a first light-transmitting opening 61 is provided on the pixel definition layer 6; the light-shielding layer 7 is disposed on the side away from the substrate 1 of the pixel definition layer 6, and a second light-transmitting opening 71 is provided on the light-shielding layer 7. The orthographic projection of the second light-transmitting opening 71 on the substrate 1 at least partially overlaps with the orthographic projection of the first light-transmitting opening 61 on the substrate 1; the first source-drain conductive layer 2 includes at least two data lines 21, and the at least two data lines 21 extend along the second direction. At least one data line is provided on each side of the first light-transmitting opening 61 along the first direction. The second source-drain conductive layer 4 includes a reset signal line 41 and a transfer line 42. The reset signal line 41 and the transfer line 42 extend along the first direction, and the reset signal line 41 and the transfer line 42 are respectively disposed on both sides of the first light-transmitting opening 61 along the second direction; the reset signal line 41 includes a reset trace 411 and a first transfer portion 412. The first transfer portion 412 is connected to the reset trace 411, and at least part of the first transfer portion 412 is disposed on the side of the reset trace 411 close to the first light-transmitting opening 61. The transfer line 42 includes a transfer trace 421 and a second transfer portion 422. The second transfer portion 422 is connected to the transfer trace 421, and at least part of the second transfer portion 422 is disposed on the side of the transfer trace 421 close to the first light-transmitting opening 61. Both the first transfer portion 412 and the second transfer portion 422 are located between the two data lines 21; the second source-drain conductive layer 4 further includes at least two first conductive portions 43. At least one first conductive portion 43 is provided on each side of the first light-transmitting opening 61 along the first direction. The orthographic projection of the first conductive portions 43 on the same side of the first light-transmitting opening 61 on the substrate 1 overlaps with the orthographic projection of the data lines 21 on the substrate 1. The first source-drain conductive layer 2 further includes a second conductive portion 23 and a third conductive portion 24. The orthographic projection of the second conductive portion 23 on the substrate 1 overlaps with the orthographic projection of the first transfer portion 412 on the substrate 1, and the orthographic projection of the third conductive portion 24 on the substrate 1 overlaps with the orthographic projection of the second transfer portion 422 on the substrate 1.
[0048] The display panel includes a first conductive portion 43, a second conductive portion 23 and a third conductive portion 24. The orthographic projection of the first conductive portion 43 on the substrate 1 overlaps with the orthographic projection of the data line 21 on the substrate 1, the orthographic projection of the second conductive portion 23 on the substrate 1 overlaps with the orthographic projection of the first adapter portion 412 on the substrate 1, and the orthographic projection of the third conductive portion 24 on the substrate 1 overlaps with the orthographic projection of the second adapter portion 422 on the substrate 1. The structures of the driving circuit layers on both sides of the second light-transmitting opening 71 in the first direction and the second direction are symmetrical, and the reflection of the driving circuit layers on the ambient light in the first direction and the second direction is the same. The light incident from the second light-transmitting opening 71 has the same optical path when it is transmitted in the first direction and the second direction, which reduces the intensity difference reaching the light sensor 11. When the display device 200 is rotated back and forth, the brightness change of the screen is reduced or eliminated, thereby improving the user experience.

The N-type transistor has a small leakage current, so as to avoid leakage of the second node N2 through the second transistor T2 during the light-emitting stage.Meanwhile, the first transistor T1, the driving transistor T3, the fourth transistor T4, the fifth transistor T5, the sixth transistor T6, the seventh transistor T7, and the eighth transistor T8 can be P-type transistors. For example, the driving transistor T3, the fourth transistor T4, the fifth transistor T5, the sixth transistor T6, the seventh transistor T7, and the eighth transistor T8 can be P-type low-temperature polycrystalline silicon transistors. P-type transistors have a high carrier mobility, which is beneficial to realizing a display panel with high resolution, high response speed, high pixel density, and high aperture ratio. The first initial signal terminal, the second initial signal terminal, and the third initial signal terminal can output the same or different voltage signals according to the actual situation.

The driving circuit layer includes a first source-drain conductive layer 2, a first planarization layer 3, a second source-drain conductive layer 4, and a second planarization layer 10. The second source-drain conductive layer 4 is provided on one side of the substrate 1.

[0052] The display panel further includes a color filter layer provided on the side of the pixel definition layer 6 away from the substrate 1. A plurality of first light-transmitting openings 61 are provided on the pixel definition layer 6. The first light-transmitting openings 61 are usually located between adjacent pixel openings (not shown in the figure). The color filter layer includes a light-shielding layer 7. A second light-transmitting opening 71 is provided on the light-shielding layer 7. The second light-transmitting openings 71 are usually located between adjacent color-resist openings. The orthographic projection of the pixel opening on the substrate 1 is usually located within the orthographic projection of the color-resist opening on the substrate 1. The orthographic projection of the second light-transmitting opening 71 on the substrate 1 and the orthographic projection of the first light-transmitting opening 61 on the substrate 1 overlap at least partially. In this embodiment, the orthographic projection of the second light-transmitting opening 71 on the substrate 1 is located within the orthographic projection of the first light-transmitting opening 61 on the substrate 1. In other embodiments, it may also be that the orthographic projection of the first light-transmitting opening 61 on the substrate 1 is located within the orthographic projection of the second light-transmitting opening 71 on the substrate 1.
[0053] On both sides of the first light-transmitting opening along the first direction and on both sides along the second direction, a first source-drain metal layer and a second source-drain metal layer are provided. The structures of the driving circuit layers on both sides of the second light-transmitting opening 71 along the first direction and on both sides along the second direction are symmetric. The reflections of the driving circuit layers on the ambient light in the first direction and the second direction are the same. The optical paths of the light incident from the second light-transmitting opening 71 are the same when transmitted in the first direction and the second direction, reducing the intensity difference reaching the light sensor 11.
[0054] As Figure 6 shown, the first source-drain conductive layer 2 includes two data lines 21, and the data lines 21 are used to provide Figure 4 the data signal terminal Da in. The two data lines 21 extend along the second direction and are arranged on both sides of the first light-transmitting opening 61 along the first direction. The data line 21 includes a first data segment 211, a second data segment 212, and a third data segment 213. Both ends of the first data segment 211 are respectively connected to a second data segment 212. The ends of the second data segment 212 far from the first data segment 211 are respectively connected to a third data segment 213. The two third data segments 213 are located between the two first data segments 211 along the first direction. The distance between the two second data segments 212 gradually decreases along the second direction away from the first data segment 211.
[0055] The first source-drain conductive layer 2 may further include two power supply signal lines 22, and the power supply signal lines 22 are used to provide Figure 4 the power supply terminal VDD in. The two power supply signal lines 22 extend along the second direction and are arranged on both sides of the data line 21 along the first direction. The power supply signal line 22 includes a first power supply segment 221, a second power supply segment 222, and a third power supply segment 223. Both ends of the first power supply segment 221 are respectively connected to the second power supply segment 222. The end of the second power supply segment 222 far from the first power supply segment 221 is connected to the third power supply segment 223. The two third power supply segments 223 are located between the two first power supply segments 221 along the first direction. The distance between the two second power supply segments 222 gradually decreases along the second direction away from the first power supply segment 221.
[0056] Two first data segments 211 are located between two first power supply segments 221. The first data segments 211 and the first power supply segments 221 both extend along a second direction, and the distance between the first data segments 211 and the first power supply segments 221 in a first direction always remains equal. Two second data segments 212 are located between two second power supply segments 222. The second data segments 212 and the second power supply segments 222 both extend along an oblique direction, and the distance between the second data segments 212 and the second power supply segments 222 in the first direction always remains equal. Two third data segments 213 are located between two third power supply segments 223. The third data segments 213 and the third power supply segments 223 both extend along the second direction, and the distance between the third data segments 213 and the third power supply segments 223 in the first direction always remains equal. It should be noted that the oblique direction intersects with the first direction and the second direction, where the first direction is Figure 6 the x direction shown in Figure 6 and the second direction is Figure 6 the y direction shown in
[0057] The driving circuit layer may further include a second source-drain conductive layer 4. The second source-drain conductive layer 4 is disposed on a side of the first source-drain conductive layer 2 close to the substrate 1. The second source-drain conductive layer 4 includes a reset signal line 41 and a transfer line 42. The reset signal line 41 can be used to provide Figure 4 the reset signal terminal Re2 in
[0058] The reset signal line 41 and the transfer line 42 extend along the first direction. The reset signal line 41 and the transfer line 42 are respectively disposed on two sides of the first light-transmitting opening 61 along the second direction. The orthographic projection of the reset signal line 41 on the substrate 1 overlaps with the orthographic projections of the second data segments 212 and the second power supply segments 222 on the substrate 1. The orthographic projection of the transfer line 42 on the substrate 1 overlaps with the orthographic projections of the third data segments 213 and the second power supply segments 222 on the substrate 1.
[0059] The second source-drain conductive layer 4 further includes a first conductive portion 43. The orthographic projection of the first conductive portion 43 on the substrate 1 overlaps with the orthographic projection of the data line 21 on the substrate 1. The first source-drain conductive layer 2 further includes a second conductive portion 23 and a third conductive portion 24. The orthographic projection of the second conductive portion 23 on the substrate 1 overlaps with the orthographic projection of the first transfer portion 412 on the substrate 1. The orthographic projection of the third conductive portion 24 on the substrate 1 overlaps with the orthographic projection of the second transfer portion 422 on the substrate 1.
[0060] The shape and size of the first conductive portion 43, the shape and size of the second conductive portion 23, and the shape and size of the third conductive portion 24 are the same or approximately the same. The two first conductive portions are symmetrically arranged in the first direction, and the second conductive portion 23 and the third conductive portion 24 are also symmetrically arranged in the second direction. The number of the first conductive portions 43 is two, and the two first conductive portions 43 are located on the same straight line in the first direction. The second conductive portion 23 and the third conductive portion 24 are located on the same straight line in the second direction.
[0061] In order to better determine the setting positions of the two first conductive portions 43 and avoid the two first conductive portions 43 being misaligned with each other in the second direction, the center line of the first conductive portion 43 in the first direction overlaps with the center line of the second light-transmitting opening 71 in the first direction. In order to better determine the setting positions of the second conductive portion 23 and the third conductive portion 24 and avoid the second conductive portion 23 and the third conductive portion 24 being misaligned with each other in the first direction, the center line of the second conductive portion 23 and the third conductive portion 24 in the second direction overlaps with the center line of the second light-transmitting opening 71 in the second direction.
[0062] It should be noted that the center line of the first conductive portion 43 in the first direction and the center line of the second light-transmitting opening 71 in the first direction may be approximately overlapped. Due to process errors, the incomplete overlap, as long as the distance between the center line of the first conductive portion 43 in the first direction and the center line of the second light-transmitting opening 71 in the first direction is less than a certain value, it can be considered as overlapping. The center line of the second conductive portion 23 and the third conductive portion 24 in the second direction and the center line of the second light-transmitting opening 71 in the second direction may be approximately overlapped. Due to process errors, the incomplete overlap, as long as the distance between the center line of the second conductive portion 23 and the third conductive portion 24 in the second direction and the center line of the second light-transmitting opening 71 in the second direction is less than a certain value, it can be considered as overlapping.
[0063] The suspended first conductive part 43, the second conductive part 23 and the third conductive part 24 are prone to static electricity accumulation, which generates static electricity during the display process. The static electricity discharge will damage the transistor, causing the pixel driving circuit to be abnormal, thereby failing to effectively drive the light-emitting device, resulting in dark spots on the display panel. Therefore, a transfer line 42 is provided to be connected to the two power signal lines 22 through the first via hole 31 on the second planarization layer 10, the first conductive part 43 is connected to the data line 21 through the second via hole 32 on the second planarization layer 10, the second conductive part 23 is connected to the first transfer part 412 through the third via hole 33 on the second planarization layer 10, and the third conductive part 24 is connected to the second transfer part 422 through the fourth via hole 34 on the second planarization layer 10.
[0064] The orthographic projection of the reset signal line 41 on the substrate 1 overlaps with the orthographic projection of the second data segment 212 on the substrate 1, the first adapter portion 412 extends from between the two second data segments 212 to between the two first data segments 211, the second conductive portion 23 is located between the two first data segments 211 along the first direction, the orthographic projection of the adapter line 42 on the substrate 1 overlaps with the orthographic projection of the third data segment 213 on the substrate 1, the second adapter portion 422 extends from between the two third data segments 213 to between the two first data segments 211, and the third conductive portion 24 is located between the two first data segments 211 and the two second data segments 212 along the first direction.
[0065] The second adapter portion 422 includes a first sub-adapter portion 4221 and a second sub-adapter portion 4222. The first sub-adapter portion 4221 extends from between the two third data segments 213 to between the two second data segments 212. The second sub-adapter portion 4222 is connected to a side of the first sub-adapter portion 4221 close to the first light-transmitting opening 61. The second sub-adapter portion 4222 extends from between the two second data segments 212 to between the two first data segments 211. The distance between the edge of the second sub-adapter portion 4222 and the edge of the first data segment 211 is greater than the distance between the first sub-adapter portion 4221 and the edge of the first data segment 211. The orthographic projection of the third conductive portion 24 on the base substrate 1 is located within the orthographic projection of the second sub-adapter portion 4222 on the base substrate 1. The third conductive portion 24 is connected to the second sub-adapter portion 4222 through the fourth via 34.
[0066] The orthographic projection of the second conductive portion 23 on the substrate 1 is the first orthographic projection, the orthographic projection of the first adapter portion 412 on the substrate 1 is the second orthographic projection, the orthographic projection of the third conductive portion 24 on the substrate 1 is the third orthographic projection, and the orthographic projection of the second sub-adapter portion 4222 on the substrate 1 is the fourth orthographic projection. The two sides of the first orthographic projection in the first direction overlap with the two sides of the second orthographic projection in the first direction, and the two sides of the fourth orthographic projection in the first direction overlap with the two sides of the third orthographic projection in the first direction.
[0067] The two sides of the first orthographic projection in the first direction and the two sides of the second orthographic projection in the first direction can be approximately overlapped. Due to the incomplete overlap caused by process errors, if the distance between the two sides of the first orthographic projection in the first direction and the two sides of the second orthographic projection in the first direction is less than a certain value, it can be considered as overlap. The two sides of the fourth orthographic projection in the first direction and the two sides of the third orthographic projection in the first direction can be approximately overlapped. Due to the incomplete overlap caused by process errors, if the distance between the two sides of the fourth orthographic projection in the first direction and the two sides of the third orthographic projection in the first direction is less than a certain value, it can be considered as overlap.
[0068] The closer the edge distance between the orthographic projection of the second conductive part 23 and the third conductive part 24 on the substrate 1 and the orthographic projection of the first light-transmitting opening 61 on the substrate 1 in the first direction is, the better. The closer the edge distance between the orthographic projection of the first conductive part 43 on the substrate 1 and the orthographic projection of the first light-transmitting opening 61 on the substrate 1 in the second direction is, the better. In this embodiment, the orthographic projections of the second conductive part 23 and the third conductive part 24 on the substrate 1 can respectively overlap with the edges of the orthographic projection of the first light-transmitting opening 61 on the substrate 1 in the first direction, and the orthographic projection of the first conductive part 43 on the substrate 1 overlaps with the orthographic projection of the first light-transmitting opening 61 on the substrate 1.
[0069] The orthographic projections of the second conductive part 23 and the third conductive part 24 on the substrate 1 can be approximately overlapped with the edges of the orthographic projection of the first light-transmitting opening 61 on the substrate 1 in the first direction. Due to the incomplete overlap caused by process errors, if the distance between the orthographic projections of the second conductive part 23 and the third conductive part 24 on the substrate 1 and the edges of the orthographic projection of the first light-transmitting opening 61 on the substrate 1 in the first direction is less than a certain value, it can be considered as overlap. The orthographic projection of the first conductive part 43 on the substrate 1 and the orthographic projection of the first light-transmitting opening 61 on the substrate 1 can be approximately overlapped. Due to the incomplete overlap caused by process errors, if the distance between the edges of the orthographic projection of the first conductive part 43 on the substrate 1 and the orthographic projection of the first light-transmitting opening 61 on the substrate 1 is less than a certain value, it can be considered as overlap.
[0070] As Figure 7 shown, to further optimize the film layer consistency of the driving circuit layer around the second light-transmitting opening 71, the two sides of the second conductive part 23 and the third conductive part 24 are extended along the first direction to the edge close to the data line 21. Since the distance between adjacent first data segments 211 is greater than most of the distances between adjacent second data segments 212, and a part of the third conductive part 24 is located between adjacent second data segments 212, the distance between the edge of the third conductive part 24 and the second data segment 212 is less than the distance between the edge of the third conductive part 24 and the first data segment 211.
[0071] On the premise of ensuring that the power signal, the second reset signal and the data signal are not short-circuited, the distances between the second conductive part 23 and the third conductive part 24 and the data line 21 are made as small as possible, so as to ensure that the second conductive part 23 and the third conductive part 24 cover the second light-transmitting opening along the first direction as much as possible, such that the ratio of the length of the reflection part of the driving circuit layer in the second direction of the second light-transmitting opening 71 to the size of the second light-transmitting opening along the second direction is basically the same as the ratio of the length of the reflection part of the driving circuit layer in the first direction of the second light-transmitting opening 71 to the size of the second light-transmitting opening along the first direction. That is, when the size of the first conductive part 43 along the second direction is greater than or equal to the size of the second light-transmitting opening along the second direction, the sizes of the second conductive part 23 and the third conductive part 24 along the first direction are also as large as possible and greater than or equal to the size of the second light-transmitting opening along the first direction. In the embodiment, the distance d1 between the edge of the second conductive part 23 and the edge of the first data segment 211 may be greater than or equal to 2 micrometers, and the distance d2 between the edge of the third conductive part 24 and the edge of the second data segment 212 may be greater than or equal to 2 micrometers.
[0072] As Figure 7 shown, when the shape of the second light-transmitting opening 71 is rectangular, the size of the second light-transmitting opening 71 in the second direction is smaller, and most of the third conductive part 24 is located between adjacent first data segments 211. While ensuring that the second conductive part 23 and the third conductive part 24 are close to the first data segment 211, it can also ensure that the distance between the edge of the second conductive part 23 and the edge of the first data segment 211 in the first direction is less than or equal to the distance between the edge of the third conductive part 24 and the edge of the first data segment 211 in the first direction.
[0073] The orthographic projection of the second conductive part 23 on the substrate 1 is the first orthographic projection, the orthographic projection of the first transfer part 412 on the substrate 1 is the second orthographic projection, the orthographic projection of the third conductive part 24 on the substrate 1 is the third orthographic projection, the orthographic projection of the second sub-transfer part 4222 on the substrate 1 is the fourth orthographic projection, the orthographic projection of the first data segment 211 on the substrate 1 is the fifth orthographic projection. The edge of the first orthographic projection is located between the edge of the second orthographic projection and the edge of the fifth orthographic projection in the first direction, and the two sides of the fourth orthographic projection in the first direction overlap with the two sides of the third orthographic projection in the first direction. Here, the two sides of the fourth orthographic projection in the first direction and the two sides of the third orthographic projection in the first direction may also be approximately overlapped. Here, when the distance between the two sides of the fourth orthographic projection in the first direction and the two sides of the third orthographic projection in the first direction is less than a certain value, it can be considered as overlapping.
[0074] When the sizes of the second conductive part 23 and the third conductive part 24 in the first direction are smaller than the size of the second light-transmitting opening 71 in the first direction, if the second conductive part 23 and the third conductive part 24 are misaligned, it is easy to cause the optical paths of ambient light transmitted on both sides of the second light-transmitting opening 71 in the second direction to be inconsistent. Therefore, the sizes of the second conductive part 23 and the third conductive part 24 in the first direction are set to be greater than or equal to the size of the second light-transmitting opening 71 in the first direction. In this way, when light is incident along the second light-transmitting opening 71, the reflection sizes of the second conductive part 23 and the third conductive part 24 on both sides of the second light-transmitting opening 71 in the second direction are the same, both equal to the size of the second light-transmitting opening 71 in the first direction, which can ensure that the optical paths of ambient light transmitted on both sides of the second light-transmitting opening 71 in the second direction are the same.
[0075] In order to better ensure that the optical paths of the light incident from the second light-transmitting opening 71 are the same when transmitting in the first direction and the second direction, the shapes and sizes of the first conductive part 43, the second conductive part 23, and the third conductive part 24 are the same. This can avoid differences in the reflection of ambient light due to differences in the edge shapes, resulting in differences in the half-life angles in the first direction and the second direction.
[0076] As Figure 8 shown, in order to further reduce the difference in the half-life angles of the display panel in the first direction and the second direction, both the first light-transmitting opening 61 and the second light-transmitting opening 71 are regular polygon openings. For the convenience of setting the first conductive part 43, the second conductive part 23, and the second conductive part 23, the number of sides of the polygon opening is usually an even number. For example, the shapes of the first light-transmitting opening 61 and the second light-transmitting opening 71 are octagonal openings or dodecagonal openings, which can reduce the difference in the light incident amounts of the second light-transmitting opening 71 in multiple directions. As Figure 9 and Figure 10 shown, in order to further reduce the difference in the light incident amounts of the second light-transmitting opening 71 in multiple directions, the shapes of the first light-transmitting opening 61 and the second light-transmitting opening 71 can be set as circular.
[0077] When the second light-transmitting opening 71 is set as a regular polygon or a circle while keeping the light-transmitting area of the second light-transmitting opening 71 unchanged, the size of the second light-transmitting opening 71 in the second direction will become larger, resulting in the second conductive part 23 moving upward in the second direction and the third conductive part 24 moving downward in the second direction, making most of the third conductive part 24 located between adjacent second data segments 212, and causing the size of the third conductive part 24 in the first direction to shrink. After the size of the third conductive part 24 in the first direction shrinks, the distance between the edge of the second conductive part 23 and the edge of the first data segment 211 in the first direction is smaller than the distance between the edge of the third conductive part 24 and the edge of the first data segment 211 in the first direction.
[0078] As Figure 10As shown, the second light-transmitting opening 71 not only has consistent light entering amounts in the first direction and the second direction, but also has consistent light entering amounts in other directions on the circumference (eg, the oblique direction z).
[0079] When the second light-transmitting opening 71 is a circular opening, at least one side of the first conductive portion 43 and the first data segment 211 close to the second light-transmitting opening 71 is an arc-shaped recessed in a direction away from the second light-transmitting opening 71, at least one side of the second conductive portion 23 and the first adapter portion 412 close to the second light-transmitting opening 71 is an arc-shaped recessed in a direction away from the second light-transmitting opening 71, and at least one side of the third conductive portion 24 and the second adapter portion 422 close to the second light-transmitting opening 71 is an arc-shaped recessed in a direction away from the second light-transmitting opening 71.
[0080] Of course, the two sides of the first conductive portion 43 and the first data segment 211 close to and away from the second light-transmitting opening 71 may be set to be arc-shaped concave in the direction away from the second light-transmitting opening 71, the two sides of the second conductive portion 23 and the first adapter portion 412 close to and away from the second light-transmitting opening 71 may be set to be arc-shaped concave in the direction away from the second light-transmitting opening 71, and the two sides of the third conductive portion 24 and the second adapter portion 422 close to and away from the second light-transmitting opening 71 may be set to be arc-shaped concave in the direction away from the second light-transmitting opening 71. When the two sides of the third conductive portion 24 and the second adapter portion 422 are set to be arc-shaped, the restriction on the size of the third conductive portion 24 in the first direction caused by the change in the spacing between adjacent second data segments 212 can be reduced or eliminated.
[0081] It can be understood that in addition to the symmetrical structure of the driving circuit layer on both sides of the first direction and the second direction of the second light-transmitting opening 71, the structure of the driving circuit layer in other directions on the circumference (for example, the oblique direction z) is also basically symmetrical. Therefore, the driving circuit layer reflects ambient light the same way on the entire circumference, and the light incident from the second light-transmitting opening 71 has a consistent optical path when transmitted in the circumferential direction, thereby ensuring that the light intensity reaching the light sensor 11 from all directions is basically consistent.
[0082] It should be noted that only a section of the first data segment 211 close to the second light-transmitting opening 71 is an arc segment. The arc edge of the first conductive portion 43, the arc edge of the first data segment 211, the arc edge of the second conductive portion 23, the arc edge of the first adapter portion 412, the arc edge of the third conductive portion 24, and the arc edge of the second adapter portion 422 can have the same arc as the second light-transmitting opening 71, so as to avoid the difference in the amount of light entering and the difference in the reflection of ambient light caused by the difference in arc.
[0083] The embodiment of the present invention further provides a display device 200, which may include any display panel of the above embodiment of the present invention. The specific structure and beneficial effects of the display panel have been described in detail above, so they will not be repeated here.
