Light incident from the second light-transmitting opening travels along the same light path in the first and second directions, reducing the intensity difference reaching the light sensor. This reduces or eliminates the brightness change of the screen when the display device is rotated back and forth, improving the user experience.

Detailed Implementation

[0035] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted. Furthermore, the drawings are merely illustrative of the invention and are not necessarily drawn to scale.

[0036] 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, these terms are used only for convenience, such as according to the orientation of the examples in the accompanying drawings. It is 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 "upper" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0037] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0038] To achieve a thinner display panel with lower power consumption, the polarizer was removed. A color filter layer was placed on the side of the encapsulation layer (COE, Color On Encapsulation) away from the substrate, filtering the light emitted from the light-emitting layer. The color filter layer includes a light-shielding layer with a second light-transmitting opening. A light sensor was located on the side of the substrate away from the second source / drain conductive layer. Ambient light passed through the second and first light-transmitting openings to the light sensor, which then collected the external light intensity to adjust the screen's brightness in real time. Alternatively, a heat sensor could be placed on the side of the substrate away from the second source / drain conductive layer to regulate the screen's temperature. A pressure-sensitive sensor could also be placed on the side of the substrate away from the second source / drain conductive layer to adjust the screen's touch sensitivity.

[0039] To further improve the rationality of screen brightness conditions, the concept of field of view for the light sensor 11 is proposed, and the field of view capability of the display panel is characterized by testing the half-fading angle. Figure 1 shows the test fixture 100 for the half-fading angle. The test method is as follows: the light source moves upwards with an angle. When it is directly above the display device 200, the ambient light brightness collected by the light sensor 11 is recorded as A0. The light source is rotated clockwise or counterclockwise until the brightness collected by the light sensor 11 becomes 0.5*A0, and the angle θ corresponding to the light source at this time is recorded. This angle is the half-fading angle in the second direction. The display device 200 is rotated 90 degrees, and the half-fading angle in the first direction is tested according to the above method.

[0040] Generally, a larger half-fading angle is better, indicating that under the same environment, the screen brightness will not change when the display device 200 is rotated by a certain angle, resulting in a better user experience. As shown in Figure 2, tests on the display device 200 with a color filter layer revealed a significant difference in the half-fading angle between the first and second directions. This means that under the same ambient light conditions, the screen brightness will change noticeably depending on whether the user uses the display device 200 horizontally or vertically. Rotating the display device 200 back and forth causes the screen brightness to switch back and forth, creating a flickering effect and negatively impacting the user experience.

[0041] As shown in Figure 2, when ambient light enters the light sensor 11 sequentially through the second light-transmitting opening 71 and the first light-transmitting opening 61, the display panel exhibits different positive brightness X+ along the positive direction of the first direction x and different negative brightness X- along the negative direction of the first direction x at different test angles. Similarly, the display panel exhibits different positive brightness Y+ along the positive direction of the second direction y and different negative brightness Y- along the negative direction of the second direction y at different test angles. 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.

[0042] Table 1. Brightness changes collected by light sensor 11 in the first direction (x) and the second direction (y) at different test angles.

[0043] The main reasons for the difference in half-decay angles in the first and second directions are as follows:

[0044] Typically, the second light-transmitting opening 71 is rectangular. Therefore, the size of the second light-transmitting opening 71 in the first direction differs from its size in the second direction, resulting in an inherent inconsistency in the amount of light entering the first and second directions. A larger size of the second light-transmitting opening 71 in either the first or second direction is more beneficial for the half-fade angle. For a rectangular second light-transmitting opening 71, the size of the second light-transmitting opening 71 in the first direction is larger than its size in the second direction. The reflection of ambient light by the driving circuit layer differs in the first and second directions, resulting in a different light path for light incident from the second light-transmitting opening 71 during transmission in the first and second directions, causing 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.

[0045] As shown in Figure 3, in order to improve the pixel density of the display panel, the data line 21 is usually placed on the first source-drain conductive layer 2, and a connection part 214 is provided on the data line 21. A second source-drain conductive layer 4 is provided on the side of the first source-drain conductive layer 2 close to the substrate 1. A first conductive part 43 is provided on the second source-drain conductive layer 4. The connection part 214 is connected to the first conductive part 43 through a second via 32 on the second planarization layer.

[0046] Because the distance between the connection portion 214 and the lower layer traces is relatively large, the first conductive portion 43 can be connected to the third source-drain conductive layer, which is closer to the substrate 1 than the second source-drain conductive layer 4. The third source-drain conductive layer (not shown in FIG3) typically houses the source or drain of a transistor, thereby inputting or outputting data signals to the corresponding transistors. This reduces the parasitic capacitance of the data line 21 and avoids excessive parasitic capacitance causing delays in the data signal. When pixel density requirements are 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, the source or drain of a transistor is housed in the second source-drain conductive layer 4.

[0047] As shown in Figure 3, ambient light at small angles can pass through the second light-transmitting opening 71 and the first light-transmitting opening 61 in sequence and directly enter the light sensor 11 in the middle. Ambient light at large angles 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. 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 large angles before entering 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 they do not affect the ambient light in the second direction y. Ambient light at small and large angles in the second direction y can directly enter the light sensor 11.

[0048] Based on this, embodiments of the present invention provide a display module. As shown in Figures 4 to 10, 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 of the first source / drain conductive layer 2 away from or close to the substrate 1. The pixel definition layer 6 is disposed on the side of the driving circuit layer away from the substrate 1, and the pixel definition layer 6 has a first light-transmitting opening 61. The light-shielding layer 7 is disposed on the side of the pixel definition layer 6 away from the substrate 1, and the light-shielding layer 7 has a first light-transmitting opening 61. Two light-transmitting openings 71 are provided, the orthographic projection of the second light-transmitting opening 71 on the substrate 1 at least partially overlapping 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 extending along a second direction, and 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 an adapter line 42 extending along the first direction, and the reset signal line 41 and the adapter line 42 are respectively provided on both sides of the first light-transmitting opening 61 along the second direction; the reset signal line 41 is located on the first light-transmitting opening 61. Data line 41 includes a reset trace 411 and a first adapter 412. The first adapter 412 is connected to the reset trace 411 and is at least partially located on the side of the reset trace 411 near the first light-transmitting opening 61. Adapter line 42 includes an adapter trace 421 and a second adapter 422. The second adapter 422 is connected to the adapter trace 421 and is at least partially located on the side of the adapter trace 421 near the first light-transmitting opening 61. Both the first adapter 412 and the second adapter 422 are located between the two data lines 21. The second source / drain conductive layer 4 also includes at least two... The first conductive part 43 is provided on both sides of the first light-transmitting opening 61 along the first direction. The orthographic projection of the first conductive part 43 on the substrate 1 on the same side of the first light-transmitting opening 61 overlaps with the orthographic projection of the data line 21 on the substrate 1. The first source-drain conductive layer 2 also includes a second conductive part 23 and a third conductive part 24. The orthographic projection of the second conductive part 23 on the substrate 1 overlaps with the orthographic projection of the first adapter part 412 on the substrate 1. The orthographic projection of the third conductive part 24 on the substrate 1 overlaps with the orthographic projection of the second adapter part 422 on the substrate 1.

[0049] The display panel includes a first conductive part 43, a second conductive part 23, and a third conductive part 24. The orthographic projection of the first conductive part 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 part 23 on the substrate 1 overlaps with the orthographic projection of the first adapter part 412 on the substrate 1. The orthographic projection of the third conductive part 24 on the substrate 1 overlaps with the orthographic projection of the second adapter part 422 on the substrate 1. The drive circuit layers on both sides of the second light-transmitting opening 71 in the first and second directions have symmetrical structures. The drive circuit layers in the first and second directions reflect ambient light in the same way. The light incident from the second light-transmitting opening 71 travels along the same light path in the first and second directions, reducing the intensity difference reaching the light sensor 11. The brightness change of the screen is reduced or eliminated when the display device 200 is rotated back and forth, improving the user experience.

[0050] The display module involved in the embodiments of the present invention will be described in detail below with reference to specific examples.

[0051] As shown in Figure 4, the pixel driving circuit may include: a driving transistor T3, a first transistor T1, a second transistor T2, a fourth transistor T4, a fifth transistor T5, a sixth transistor T6, a seventh transistor T7, an eighth transistor T8, and a capacitor C. Specifically, the first terminal of the fourth transistor T4 is connected to the data signal terminal Da, the second terminal of the fourth transistor T4 is connected to the first terminal of the driving transistor T3 at the first node N1, and the gate of the fourth transistor T4 is connected to the second gate driving signal terminal G2. The first terminal of the fifth transistor T5 is connected to the power supply terminal VDD, the second terminal of the fifth transistor T5 is connected to the first terminal of the driving transistor T3, and the gate of the fifth transistor T5 is connected to the enable signal terminal EM. The gate of the driving transistor T3 is connected to the second node N2. The first terminal of the second transistor T2 is connected to the second node N2, the second terminal of the second transistor T2 is connected to the second terminal of the driving transistor T3, and the gate of the second transistor T2 is connected to the first gate driving signal terminal G1. The first terminal of the sixth transistor T6 and the second terminal of the driving transistor T3 are connected at the third node N3. The first electrode of transistor T7 is connected to the second electrode of transistor T7, the gate of transistor T6 is connected to the enable signal terminal EM, the first electrode of transistor T7 is connected to the second initial signal terminal Vinit2, and the gate of transistor T7 is connected to the second reset signal terminal Re2; the first electrode of transistor T1 is connected to the first initial signal terminal Vinit1, the second electrode of transistor T1 is connected to the second electrode of driving transistor T3, and the gate of transistor T1 is connected to the first reset signal terminal Re1; the first electrode of transistor T8 is connected to the third initial signal terminal Vinit3, the second electrode of transistor T8 and the first electrode of driving transistor T3 are connected at the first node N1, and the gate of transistor T8 is connected to the second reset signal terminal Re2; the first electrode of capacitor C is connected to the second node N2, and the second electrode of capacitor C is connected to the power supply terminal VDD. This pixel driving circuit can be used to drive a light-emitting unit OLED. The first electrode of the light-emitting unit OLED can be connected to the second electrode of transistor T6, and the second electrode of the light-emitting unit can be connected to the second power supply terminal VSS. The first electrode of the light-emitting unit can be the anode of the light-emitting unit, and the second electrode of the light-emitting unit can be the cathode of the light-emitting unit. The second transistor T2 can be an N-type transistor, for example, an N-type metal-oxide transistor. N-type transistors have a smaller leakage current, which can avoid the light-emitting stage. The second node N2 leaks current through the second transistor T2.Meanwhile, the first transistor T1, driving transistor T3, fourth transistor T4, fifth transistor T5, sixth transistor T6, seventh transistor T7, and eighth transistor T8 can be P-type transistors. For example, driving transistor T3, fourth transistor T4, fifth transistor T5, sixth transistor T6, seventh transistor T7, and eighth transistor T8 can be P-type low-temperature polysilicon transistors. P-type transistors have higher carrier mobility, which is beneficial for realizing display panels with high resolution, high response speed, high pixel density, and high aperture ratio. The first initial signal terminal, second initial signal terminal, and third initial signal terminal can output the same or different voltage signals according to actual conditions.

[0053] The display panel also includes a color filter layer disposed on the side of the pixel definition layer 6 away from the substrate 1. The pixel definition layer 6 has a plurality of first light-transmitting openings 61, which are typically located between adjacent pixel openings (not shown in the figure). The color filter layer includes a light-shielding layer 7, which has second light-transmitting openings 71, which are typically located between adjacent color resist openings. The orthographic projection of the pixel openings on the substrate 1 typically falls within the orthographic projection of the color resist openings on the substrate 1. 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. In this embodiment, the orthographic projection of the second light-transmitting opening 71 on the substrate 1 falls within the orthographic projection of the first light-transmitting opening 61 on the substrate 1. In other embodiments, the orthographic projection of the first light-transmitting opening 61 on the substrate 1 may also fall within the orthographic projection of the second light-transmitting opening 71 on the substrate 1.

[0054] The first light-transmitting opening has a first source / drain metal layer and a second source / drain metal layer on both sides along the first direction and both sides along the second direction. The drive circuit layers on both sides of the second light-transmitting opening 71 in the first direction and the second direction have symmetrical structures. The drive circuit layers in the first direction and the second direction reflect ambient light in the same way. The light incident from the second light-transmitting opening 71 has the same light path when it is transmitted in the first direction and the second direction, which reduces the intensity difference when it reaches the light sensor 11.

[0055] As shown in Figure 7, the first source / drain conductive layer 2 includes two data lines 21, which provide the data signal terminal Da in Figure 6. The two data lines 21 extend along a second direction and are located on both sides of the first light-transmitting opening 61 along a first direction. The data lines 21 include a first data segment 211, a second data segment 212, and a third data segment 213. The two ends of the first data segment 211 are respectively connected to a second data segment 212, and the ends of the second data segment 212 away 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, and the distance between the two second data segments 212 gradually decreases along the second direction away from the first data segment 211.

[0056] The first source / drain conductive layer 2 may further include two power signal lines 22, which are used to provide the power terminal VDD in FIG6. The two power signal lines 22 extend along a second direction and are located on both sides of the data line 21 along a first direction. The power signal lines 22 include a first power segment 221, a second power segment 222, and a third power segment 223. The two ends of the first power segment 221 are respectively connected to the second power segment 222. The end of the second power segment 222 away from the first power segment 221 is connected to the third power segment 223. The two third power segments 223 are located between the two first power segments 221 along the first direction. The distance between the two second power segments 222 gradually decreases along the second direction away from the first power segment 221.

[0057] Two first data segments 211 are located between two first power segments 221. Both the first data segments 211 and the first power segments 221 extend along the second direction, and the distance between them in the first direction remains equal. Two second data segments 212 are located between two second power segments 222. Both the second data segments 212 and the second power segments 222 extend along an oblique direction, and the distance between them in the first direction remains equal. Two third data segments 213 are located between two third power segments 223. Both the third data segments 213 and the third power segments 223 extend along the second direction, and the distance between them in the first direction remains equal. It should be noted that the oblique direction intersects with the first and second directions, where the first direction is the x-direction shown in Figure 7, the second direction is the y-direction shown in Figure 7, and the oblique direction is the z-direction shown in Figure 7.

[0058] The driving circuit layer may further include a second source / drain conductive layer 4. The second source / drain conductive layer 4 is disposed on the side of the first source / drain conductive layer 2 near the substrate 1. The second source / drain conductive layer 4 includes a reset signal line 41 and a transition line 42. The reset signal line 41 can be used to provide the reset signal terminal Re2 in FIG. 6. The reset signal line 41 and the transition line 42 extend along a first direction and are respectively disposed on both sides of the first light-transmitting opening 61 along a second direction. The orthographic projection of the reset signal line 41 on the substrate 1 overlaps with the orthographic projection of the second data segment 212 and the second power segment 222 on the substrate 1. The orthographic projection of the transition line 42 on the substrate 1 overlaps with the orthographic projection of the third data segment 213 and the second power segment 222 on the substrate 1.

[0059] The reset signal line 41 includes a reset trace 411 and a first adapter 412. The first adapter 412 is connected to the reset trace 411 and is at least partially located on the side of the reset trace 411 near the first light-transmitting opening 61. The adapter line 42 includes an adapter trace 421 and a second adapter 422. The second adapter 422 is connected to the adapter trace 421 and is at least partially located on the side of the adapter trace 421 near the first light-transmitting opening 61. Both the first adapter 412 and the second adapter 422 are located between the two data lines 21.

[0060] The second source-drain conductive layer 4 also 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 also 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 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.

[0061] The first conductive part 43, the second conductive part 23, and the third conductive part 24 are the same or approximately the same in shape and size. The two first conductive parts are symmetrically arranged in the first direction, and the second conductive part 23 and the third conductive part 24 are also symmetrically arranged in the second direction. There are two first conductive parts 43, which are located on the same straight line along the first direction. The second conductive part 23 and the third conductive part 24 are located on the same straight line along the second direction.

[0062] To better determine the placement of the two first conductive parts 43 and avoid misalignment of the two first conductive parts 43 in the second direction, the center line of the first conductive part 43 in the first direction overlaps with the center line of the second light-transmitting opening 71 in the first direction. Similarly, to better determine the placement of the two second conductive parts 23 and the third conductive part 24 and avoid misalignment of the second conductive parts 23 and the third conductive part 24 in the first direction, the center lines of the second conductive parts 23 and the third conductive part 24 in the second direction overlap with the center line of the second light-transmitting opening 71 in the second direction.

[0063] It should be noted that the center line of the first conductive part 43 in the first direction and the center line of the second light-transmitting opening 71 in the first direction may approximately overlap. Due to process errors, they may not completely overlap. As long as the distance between the center lines of the first conductive part 43 in the first direction and the center lines of the second light-transmitting opening 71 in the first direction is less than a certain value, they can be considered to overlap. Similarly, the center lines of the second conductive part 23 and the third conductive part 24 in the second direction and the center lines of the second light-transmitting opening 71 in the second direction may approximately overlap. Due to process errors, they may not completely overlap. As long as the distance between the center lines of the second conductive part 23 and the third conductive part 24 in the second direction and the center lines of the second light-transmitting opening 71 in the second direction is less than a certain value, they can be considered to overlap.

[0064] The suspended first conductive part 43, second conductive part 23, and third conductive part 24 are prone to static electricity accumulation. During the display process, static electricity is generated, and electrostatic discharge can damage the transistors, causing abnormalities in the pixel driving circuit. As a result, the light-emitting devices cannot be effectively driven, leading to dark spots on the display panel. Therefore, the adapter cable 42 is connected to the two power signal lines 22 through the first via 31 on the second planarization layer 10, the first conductive part 43 is connected to the data line 21 through the second via 32 on the second planarization layer 10, the second conductive part 23 is connected to the first adapter part 412 through the third via 33 on the second planarization layer 10, and the third conductive part 24 is connected to the second adapter part 422 through the fourth via 34 on the second planarization layer 10.

[0065] 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 transition 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 transition line 42 on the substrate 1 overlaps with the orthographic projection of the third data segment 213 on the substrate 1. The second transition portion 422 extends from between the two third data segments 213 to between the two first data segments 211. 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.

[0066] The second adapter 422 includes a first sub-adapter 4221 and a second sub-adapter 4222. The first sub-adapter 4221 extends from between two third data segments 213 to between two second data segments 212. The second sub-adapter 4222 is connected to the side of the first sub-adapter 4221 near the first light-transmitting opening 61. The second sub-adapter 4222 extends from between two second data segments 212 to between two first data segments 211. The distance between the edge of the second sub-adapter 4222 and the edge of the first data segment 211 is greater than the distance between the edges of the first sub-adapter 4221 and the first data segment 211. The orthographic projection of the third conductive part 24 on the substrate 1 is located within the orthographic projection of the second sub-adapter 4222 on the substrate 1. The third conductive part 24 is connected to the second sub-adapter 4222 through a fourth via 34.

[0067] The orthographic projection of the second conductive part 23 on the substrate 1 is the first orthographic projection, the orthographic projection of the first transition 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, and the orthographic projection of the second sub-transition part 4222 on the substrate 1 is the fourth orthographic projection. The first orthographic projection and the second orthographic projection overlap each other on both sides of the first direction, and the fourth orthographic projection and the third orthographic projection overlap each other on both sides of the first direction.

[0068] The first orthographic projection and the second orthographic projection in the first direction can approximately overlap in their respective sides. However, due to manufacturing errors, they may not completely overlap. If the distance between the two sides of the first orthographic projection and the two sides of the second orthographic projection in the first direction is less than a certain value, they can be considered to overlap. Similarly, the fourth orthographic projection and the third orthographic projection in the first direction can approximately overlap in their respective sides. However, due to manufacturing errors, they may not completely overlap. If the distance between the two sides of the fourth orthographic projection and the two sides of the third orthographic projection in the first direction is less than a certain value, they can be considered to overlap.

[0069] The closer the orthographic projections of the second conductive portion 23 and the third conductive portion 24 on the substrate 1 are to the edge along the first direction of the orthographic projection of the first light-transmitting opening 61 on the substrate 1, the better. Similarly, the closer the orthographic projection of the first conductive portion 43 on the substrate 1 is to the edge along the second direction of the orthographic projection of the first light-transmitting opening 61 on the substrate 1, the better. In this embodiment, the orthographic projections of the second conductive portion 23 and the third conductive portion 24 on the substrate 1 can overlap with the edge along the first direction of the orthographic projection of the first light-transmitting opening 61 on the substrate 1, respectively, and the orthographic projection of the first conductive portion 43 on the substrate 1 overlaps with the orthographic projection of the first light-transmitting opening 61 on the substrate 1.

[0070] The orthographic projections of the second conductive portion 23 and the third conductive portion 24 on the substrate 1 can approximately overlap with the edge of the orthographic projection of the first light-transmitting opening 61 on the substrate 1 along the first direction. Due to process errors, the overlap may be incomplete. An overlap can be considered complete if the distance between the edges of the orthographic projections of the second conductive portion 23 and the third conductive portion 24 on the substrate 1 and the orthographic projection of the first light-transmitting opening 61 on the substrate 1 along the first direction is less than a certain value. Similarly, the orthographic projection of the first conductive portion 43 on the substrate 1 and the orthographic projection of the first light-transmitting opening 61 on the substrate 1 can approximately overlap. Due to process errors, the overlap may be incomplete. An overlap can be considered complete if the distance between the edges of the orthographic projections of the first conductive portion 43 on the substrate 1 and the first light-transmitting opening 61 on the substrate 1 is less than a certain value.

[0071] As shown in Figure 7, to further optimize the film consistency of the driving circuit layer around the second light-transmitting opening 71, the two sides of the second conductive portion 23 and the third conductive portion 24 are extended along the first direction to the edge near the data line 21. Since the distance between adjacent first data segments 211 is greater than most of the distance between adjacent second data segments 212, and a portion of the third conductive portion 24 is located between adjacent second data segments 212, the distance between the edge of the third conductive portion 24 and the second data segment 212 is less than the distance between the edge of the third conductive portion 24 and the first data segment 211.

[0072] While ensuring that the power signal, the second reset signal, and the data signal are not short-circuited, the distance between the second conductive part 23 and the third conductive part 24 and the data line 21 is minimized. This ensures that the second conductive part 23 and the third conductive part 24 cover the second light-transmitting opening as much as possible along the first direction. The ratio of the length of the reflective portion 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 approximately the same as the ratio of the length of the reflective portion 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 great as possible to be greater than or equal to the size of the second light-transmitting opening along the first direction. In this embodiment, the distance d1 between the edge of the second conductive part 23 and the edge of the first data segment 211 can 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 can be greater than or equal to 2 micrometers.

[0073] As shown in Figure 8, 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 small, and most of the third conductive part 24 is located between the adjacent first data segment 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.

[0074] The orthographic projection of the second conductive part 23 on the substrate 1 is the first orthographic projection; the orthographic projection of the first transition 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-transition part 4222 on the substrate 1 is the fourth orthographic projection; and 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 edges of the second and fifth orthographic projections in the first direction. 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 can also be approximately overlapping. Here, 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, which can be considered as an overlap.

[0075] When the dimensions of the second conductive part 23 and the third conductive part 24 in the first direction are smaller than the dimensions of the second light-transmitting opening 71 in the first direction, misalignment of the second conductive part 23 and the third conductive part 24 can easily lead to inconsistent optical paths when ambient light propagates along the second direction on both sides of the second light-transmitting opening 71. Therefore, the dimensions 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 dimensions 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 dimensions 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 dimensions of the second light-transmitting opening 71 in the first direction. This ensures that the optical paths of ambient light propagating along the second direction on both sides of the second light-transmitting opening 71 are the same.

[0076] To better ensure that the light incident from the second light-transmitting opening 71 travels along the same light path in both the first and second directions, the shapes and sizes of the first conductive part 43, the second conductive part 23, and the third conductive part 24 are identical. This avoids differences in edge shape that could lead to variations in the reflection of ambient light and cause differences in the half-decay angles in the first and second directions.

[0077] As shown in Figure 9, to further reduce the difference in half-fading angle between the display panel in the first and second directions, both the first light-transmitting opening 61 and the second light-transmitting opening 71 are regular polygonal openings. To facilitate the arrangement of the first conductive part 43, the second conductive part 23, and the second conductive part 23, the number of sides of the polygonal opening is usually even. For example, the shapes of the first light-transmitting opening 61 and the second light-transmitting opening 71 are octagonal or dodecagonal openings. This can reduce the difference in the amount of light entering the second light-transmitting opening 71 in multiple directions. As shown in Figures 10 and 11, to further reduce the difference in the amount of light entering 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 to circular.

[0078] While maintaining the same light-transmitting area, setting the second light-transmitting opening 71 as a regular polygon or a circle increases its size in the second direction. This causes the second conductive part 23 to move upward in the second direction and the third conductive part 24 to move downward in the second direction. Consequently, most of the third conductive part 24 is located between adjacent second data segments 212, resulting in a reduction in its size in the first direction. After the size of the third conductive part 24 decreases in the first direction, 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 the distance between the edge of the third conductive part 24 and the edge of the first data segment 211.

[0079] As shown in Figure 11, in addition to the consistent amount of light entering the second light-transmitting opening 71 in the first and second directions, the amount of light entering the second light-transmitting opening 71 in other directions on the circumference (e.g., the oblique direction z) can also be kept consistent.

[0080] When the second light-transmitting opening 71 is a circular opening, the first conductive part 43 and the first data segment 211 are at least on the side closest to the second light-transmitting opening 71 and are concave arc-shaped in the direction away from the second light-transmitting opening 71. The second conductive part 23 and the first transition part 412 are at least on the side closest to the second light-transmitting opening 71 and are concave arc-shaped in the direction away from the second light-transmitting opening 71. The third conductive part 24 and the second transition part 422 are at least on the side closest to the second light-transmitting opening 71 and are concave arc-shaped in the direction away from the second light-transmitting opening 71.

[0081] Alternatively, the first conductive portion 43 and the first data segment 211 can be configured with concave arc shapes on both sides near and away from the second light-transmitting opening 71, and the second conductive portion 23 and the first transition portion 412 can be configured with concave arc shapes on both sides near and away from the second light-transmitting opening 71, and the third conductive portion 24 and the second transition portion 422 can be configured with concave arc shapes on both sides near and away from the second light-transmitting opening 71. When both sides of the third conductive portion 24 and the second transition portion 422 are configured with arc shapes, the limitation on the size of the third conductive portion 24 in the first direction caused by the change in spacing between adjacent second data segments 212 can be reduced or eliminated.

[0082] It is understandable that, in addition to the symmetrical structure of the driving circuit layers on both sides of the first direction and the second direction of the second light-transmitting opening 71, the structure of the driving circuit layers in other directions (e.g., the oblique direction z) on the circumference is also basically symmetrical. Therefore, the reflection of ambient light by the driving circuit layers is the same throughout the circumference, and the light incident from the second light-transmitting opening 71 has the same light path when transmitted in the circumferential direction, thereby ensuring that the light intensity reaching the light sensor 11 from all directions is basically the same.

[0083] It should be noted that only the section of the first data segment 211 closest to the second light-transmitting opening 71 is an arc-shaped segment. The arc-shaped edges of the first conductive part 43, the first data segment 211, the second conductive part 23, the first transition part 412, the third conductive part 24, and the second transition part 422 can have the same curvature as the second light-transmitting opening 71 to avoid differences in light intake and reflection of ambient light caused by differences in curvature.

[0084] This invention also provides a display device 200, which may include the display panel described in any of the above embodiments of this invention. The specific structure and beneficial effects of the display panel have already been described in detail above, and therefore will not be repeated here.

[0085] It should be noted that, in addition to the display panel, the display device 200 also includes other necessary components and parts, such as the housing, circuit board, power cord, etc. Those skilled in the art can make corresponding additions according to the specific usage requirements of the display device 200, which will not be elaborated here.

Display device 200 can also be a traditional electronic device, such as a mobile phone, computer, television, or camcorder. These will not be listed individually here.
