[0023] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0025] Figure 1 FIG. 1 is a schematic plan view of a display panel provided by an embodiment of the present disclosure. Figure 2 Shown Figure 1 For an enlarged view of the second display area, please refer to Figures 1 to 2 The present disclosure provides a display panel 100, comprising: a first display area AA1 and a second display area AA2, wherein the light transmittance of the first display area AA1 is lower than the light transmittance of the second display area AA2; it is understood that the display panel 100 provided in the embodiment of the present disclosure is suitable for display devices that require sensors to be set under the screen, wherein the sensors can be, for example, cameras, ambient light sensors, etc. Since the shape of the area corresponding to the sensor is generally set to be circular, Figures 1 to 2The second display area AA2 is exemplarily shown as a circular area, but this does not constitute a limitation of the present disclosure. The second display area AA2 can also be a polygonal area or an elliptical area. In addition, this embodiment does not specifically limit the position of the second display area AA2 in the display panel 100. Figure 1 The second display area AA2 is located at the upper left corner of the display panel 100 for illustration only. In other optional embodiments, the second display area AA2 may also be located in the central area of ​​the display panel 100 .

[0026] Please refer to Figure 2 The second display area AA2 includes a plurality of first light-emitting element columns 11 and a plurality of second light-emitting element columns 12, which are arranged alternately along a first direction D1. The first light-emitting element columns 11 include a plurality of first light-emitting elements 01 and a plurality of second light-emitting elements 02, which are arranged alternately along a second direction D2. The second light-emitting element columns 12 include a plurality of third light-emitting elements 03 arranged along a second direction D2. Both the first direction D1 and the second direction D2 are parallel to the plane of the display panel 100, and the first direction D1 intersects the second direction D2. Figure 2 The example of a first direction D1 and a second direction D2 being perpendicular is used for illustration only and is not limited in this disclosure. The first light-emitting element 01, the second light-emitting element 02, and the third light-emitting element 03 are each one of a red light-emitting element, a green light-emitting element, and a blue light-emitting element. The green light-emitting elements in the first light-emitting element column 11 have a higher efficiency than the red light-emitting elements. In actual manufacturing processes, the area of ​​the green light-emitting elements can be slightly smaller than that of the red light-emitting elements.

[0027] Please continue to refer to Figure 2 The second display area AA2 further includes a plurality of first light-emitting element rows 21, a plurality of second light-emitting element rows 22, and a plurality of third light-emitting element rows 23. The first light-emitting element rows 21 include a plurality of first light-emitting elements 01 arranged along a first direction D1, the second light-emitting element rows 22 include a plurality of second light-emitting elements 02 arranged along the first direction D1, and the third light-emitting element rows 23 include a plurality of third light-emitting elements 03 arranged along the first direction D1. That is, the first light-emitting elements 01, the second light-emitting elements 02, and the third light-emitting elements 03 are respectively located in different light-emitting element rows 20 in the display panel 100. Optionally, each pixel of the display panel 100 provided in the embodiment of the present disclosure is composed of a complete red sub-pixel, a green sub-pixel, and a blue sub-pixel. Each sub-pixel can independently display the required color, and sub-pixels do not need to be shared between pixel groups in this arrangement.

[0028] The display panel 100 further includes a plurality of light-transmitting holes 00 located in the second display area AA2. In a plan view, the light-transmitting holes 00 are located between two adjacent third light-emitting elements 03 in the second light-emitting element column 12. Optionally, the shape of the light-transmitting holes 00 includes at least one of a circle, an ellipse, and a rounded polygon. Figure 2 The circular shape of the light-transmitting hole 00 is used for exemplary description. It should be noted that the shape of the light-transmitting hole 00 includes but is not limited to the above examples, and those skilled in the art can set the shape of the light-transmitting hole 00 according to product requirements, which is not limited in this disclosure.

[0029] Specifically, by providing multiple light-transmitting holes 00 in the second display area AA2, external light enters the sensor on the backlight side of the display panel 100 through the multiple light-transmitting holes 00, ensuring that the sensor receives sufficient light, enabling the sensor to more accurately detect the intensity of external light, thereby dynamically adjusting the screen brightness; by providing the light-transmitting holes 00 between two adjacent third light-emitting elements 03 in the second light-emitting element column 12, the existing space between the third light-emitting elements 03 can be utilized, thereby achieving a more compact pixel arrangement or a smaller pixel pitch without increasing the overall size. This can be applied to display devices with high resolution or high integration requirements. In different application scenarios, the shape, size, and position of the light-transmitting holes 00 can be adjusted as needed to achieve optimal optical performance and visual effects. In addition, this layout allows the light-transmitting holes 00 and light-emitting elements to be arranged simultaneously in the same manufacturing step, thereby simplifying the manufacturing process and reducing production costs. At the same time, by providing multiple light-emitting elements in the second display area AA2, when the display panel 100 is required to display, the normal display of the second display area AA2 can be achieved through the multiple light-emitting elements, thereby improving the screen-to-body ratio of the display panel 100 and achieving full-screen display.

[0030] Please continue to refer to Figure 2 The present disclosure provides a display panel 100 , wherein one of the first light-emitting element 01 and the second light-emitting element 02 is a red light-emitting element, the other is a green light-emitting element, and the third light-emitting element 03 is a blue light-emitting element.

[0031] Specifically, in an optional embodiment provided by the present disclosure, the display panel 100 includes a first display area AA1 and a second display area AA2, the second display area AA2 includes a first light-emitting element column 11 and a second light-emitting element column 12, the first light-emitting element column 11 and the second light-emitting element column 12 are alternately arranged along the first direction D1, the first light-emitting element column 11 includes a plurality of red light-emitting elements and a plurality of green light-emitting elements, and the red light-emitting elements and the green light-emitting elements are alternately arranged along the second direction D2; the second light-emitting element column 12 includes a plurality of blue light-emitting elements arranged along the second direction D2.

[0032] The second display area AA2 further includes a plurality of first light-emitting element rows 21, a plurality of second light-emitting element rows 22, and a plurality of third light-emitting element rows 23. The first light-emitting element rows 21 include a plurality of red light-emitting elements arranged along a first direction D1, the second light-emitting element rows 22 include a plurality of green light-emitting elements arranged along the first direction D1, and the third light-emitting element rows 23 include a plurality of blue light-emitting elements arranged along the first direction D1. Alternatively, the first light-emitting element rows 21 include a plurality of green light-emitting elements arranged along the first direction D1, and the second light-emitting element rows 22 include a plurality of red light-emitting elements arranged along the first direction D1. This is not limited in the present disclosure, as long as the red light-emitting elements, green light-emitting elements, and blue light-emitting elements are located in different light-emitting element rows 20. That is, in the embodiments of the present disclosure, each independently displayed pixel is composed of one complete red, one green, and one blue sub-pixel. Each pixel can independently display the complete color information it requires without "borrowing" sub-pixels from adjacent pixels, resulting in a clearer display image and more accurate colors on the display panel 100.

[0033] Figure 3 Shown Figure 1 Another enlarged view of the second display area, Figure 4 Shown Figure 1 For another enlarged view of the second display area, please refer to Figure 3 and Figure 4 In an optional embodiment provided by the present disclosure, the third light emitting element 03 in the second light emitting element column 12 may also be a shape including multiple curved edges, for example, it may be Figure 3 or Figure 4 The shape shown in the figure can, of course, also be other shapes including curved edges, which is not limited in the present disclosure.

[0034] Please refer to Figures 2 to 4 The present disclosure provides a display panel 100 , wherein along a first direction D1 , the third light emitting element 03 overlaps with at least one of the first light emitting element 01 and the second light emitting element 02 .

[0035] Specifically, optionally, the third light-emitting element 03 overlaps with the first light-emitting element 01 in the first direction D1, or the third light-emitting element 03 overlaps with the second light-emitting element 02 in the first direction D1, or the third light-emitting element 03 overlaps with the first light-emitting element 01 in the first direction D1, and the third light-emitting element 03 overlaps with the second light-emitting element 02 in the first direction D1. By allowing light-emitting elements of different colors to overlap in the first direction D1, sub-pixels can be arranged more closely, increasing the effective light-emitting area of ​​the display panel 100 and effectively reducing the non-light-emitting area in the display panel 100, thereby significantly improving pixel density within the same physical size. Higher pixel density can lead to higher resolution, reduce image graininess, and enhance visual detail. Furthermore, overlapping light-emitting elements of different colors in the first direction D1 allows light of different colors to mix more closely, helping to improve color uniformity, reduce the visual gap between sub-pixels of different colors, and make the color transition perceived by the human eye more natural and smoother.

[0036] Figure 5 Shown Figure 1 For another enlarged view of the second display area, please refer to Figure 5 The present disclosure provides a display panel 100 , wherein in a third light-emitting element row 23 , centers of at least some of the third light-emitting elements 03 are on a straight line L1 , and centers of at least some of the third light-emitting elements 03 are on another straight line L2 .

[0037] Specifically, in an optional embodiment provided by the present disclosure, a third light-emitting element row 23 includes multiple blue light-emitting elements, with the centers of at least some of the blue light-emitting elements aligned on a straight line L1 and at least some of the blue light-emitting elements aligned on another straight line L2. By staggering the centers of the blue light-emitting elements onto different straight lines, larger blue sub-pixels can be accommodated within a limited pixel space, as blue light-emitting elements have the shortest lifespan. This allows for more flexible pixel design, thereby increasing the physical size of the blue sub-pixels or improving their heat dissipation conditions without sacrificing overall brightness, thereby extending their lifespan and achieving more compact and efficient space utilization. Thus, by aligning the centers of at least some of the third light-emitting elements 03 in a third light-emitting element row 23 on a straight line L1 and at least some of the third light-emitting elements 03 on another straight line L2, a more flexible pixel design can be achieved, the physical size of the blue sub-pixels can be increased, and more compact and efficient space utilization can be achieved.

[0038] Please continue to refer to Figure 5 The present disclosure provides a display panel 100 , wherein along the second direction D2 , a distance H2 between two adjacent third light-emitting elements 03 is greater than a distance H1 between adjacent first light-emitting elements 01 and second light-emitting elements 02 .

[0039] Specifically, the second display area AA2 includes a first light-emitting element column 11 and a second light-emitting element column 12 alternately arranged along the first direction D1, the first light-emitting element column 11 includes a first light-emitting element 01 and a second light-emitting element 02 alternately arranged along the second direction D2, and the second light-emitting element column 12 includes a third light-emitting element 03 arranged along the second direction D2. Along the second direction D2, the distance H2 between two adjacent third light-emitting elements 03 in the second light-emitting element column 12 is greater than the distance H1 between adjacent first light-emitting elements 01 and second light-emitting elements 02 in the first light-emitting element column 11. In an optional embodiment provided in the present disclosure, one of the first light-emitting element 01 and the second light-emitting element 02 is a red light-emitting element, the other is a green light-emitting element, and the third light-emitting element 03 is a blue light-emitting element. That is, along the second direction D2, the distance H2 between two adjacent blue light-emitting elements in the second light-emitting element column 12 is greater than the distance H1 between adjacent red light-emitting elements and green light-emitting elements in the first light-emitting element column 11. Furthermore, there is sufficient space between two adjacent blue light-emitting elements along the second direction D2. Along the first direction D1, the light-transmitting hole 00 can be set between two adjacent blue light-emitting elements to utilize the existing space between the third light-emitting element 03 without increasing the existing size of the display panel 100.

[0040] Please continue to refer to Figure 5 The present disclosure provides a display panel 100 , in which, in a second light-emitting element column 12 , the distances between the light-transmitting hole 00 and two adjacent third light-emitting elements 03 along the second direction D2 are equal.

[0041] Specifically, in an optional embodiment provided by the present disclosure, the second light-emitting element column 12 includes third light-emitting elements 03 arranged along the second direction D2, and the light-transmitting hole 00 is located between two adjacent third light-emitting elements 03. Along the second direction D2, the distance between the light-transmitting hole 00 and one adjacent third light-emitting element 03 is h1, and the distance between the light-transmitting hole 00 and another adjacent third light-emitting element 03 is h1, where h1=h2. That is, along the second direction D2, the light-transmitting hole 00 is located in the middle between the two adjacent third light-emitting elements 03, and the distance between the light-transmitting hole 00 and the two adjacent third light-emitting elements 03 is equal. The uniform spacing simplifies the arrangement of the light-transmitting hole 00 and the third light-emitting element 03 and reduces the complexity of the optical design. During the manufacturing process, the standardized layout in which the light-transmitting hole 00 is located between two adjacent third light-emitting elements 03 along the second direction D2 makes it easier to achieve precise alignment, which helps to improve production efficiency and yield rate, and reduce manufacturing costs. In addition, this layout is also conducive to uniform distribution of light, improves photoelectric conversion efficiency, extends the life of the light-emitting element, and enhances visual effects. In this way, by setting the distance between the light-transmitting hole 00 and two adjacent third light-emitting elements 03 to be equal, the layout spacing can be simplified, the manufacturing process can be simplified, the uniform distribution of light can be facilitated, and the visual effect can be improved.

[0042] Please refer to Figures 2 to 5 The present disclosure provides a display panel 100 , wherein along a first direction D1 , a light-transmitting hole 00 overlaps with at least one of a first light-emitting element 01 and a second light-emitting element 02 .

[0043] Specifically, in an optional embodiment provided by the present disclosure, the first light-emitting element column 11 and the second light-emitting element column 12 are alternately arranged along the first direction D1, the first light-emitting element column 11 includes the first light-emitting element 01 and the second light-emitting element 02 alternately arranged along the second direction D2, the second light-emitting element column 12 includes the third light-emitting element 03 arranged along the second direction D2, and at least part of the third light-emitting elements 03 adjacent along the second direction D2 include a light-transmitting hole 00. Optionally, along the first direction D1, the light-transmitting hole 00 located in the second light-emitting element column 12 overlaps with the first light-emitting element 01 located in the first light-emitting element column 11, or, along the first direction D1, the light-transmitting hole 00 located in the second light-emitting element column 12 overlaps with the second light-emitting element 02 located in the first light-emitting element column 11, or, along the first direction D1, the light-transmitting hole 00 located in the second light-emitting element column 12 overlaps with both the first light-emitting element 01 and the second light-emitting element 02 located in the first light-emitting element column 11. In other words, the light-transmitting hole 00 can be expanded as much as possible within the existing spacing between adjacent third light-emitting elements 03, and can be expanded to overlap at least one of the red light-emitting element or the green light-emitting element in the first direction D1, thereby increasing the area of ​​the light-transmitting hole 00 and improving the light transmittance of the second display area AA2. In this way, by arranging the light-transmitting hole 00 to overlap at least one of the first light-emitting element 01 and the second light-emitting element 02 in the first direction D1, the size of the light-transmitting hole 00 can be maximized to increase light transmittance without changing the existing structure or size of the display panel 100.

[0044] Figure 6 Shown Figure 1 Another enlarged view of the second display area, Figure 7 Shown Figure 6 For the cross-section along the middle line B-B', please refer to Figure 6 and Figure 7 The present disclosure provides a display panel 100 , wherein the third light-emitting element 03 includes two third sub-light-emitting elements 003 , and the two third sub-light-emitting elements 003 in the same third light-emitting element 03 share a pixel circuit.

[0045] Specifically, in an optional embodiment provided by the present disclosure, the first light-emitting element column 11 and the second light-emitting element column 12 are alternately arranged along the first direction D1, the first light-emitting element column 11 includes the first light-emitting element 01 and the second light-emitting element 02 alternately arranged along the second direction D2, and the second light-emitting element column 12 includes the third light-emitting element 03 alternately arranged along the second direction D2, wherein the third light-emitting element 03 includes two third sub-light-emitting elements 003, and the two third sub-light-emitting elements 003 in the same third light-emitting element 03 share a pixel circuit. Please refer to Figure 7The two third sub-light-emitting elements 003 in a third light-emitting element 03 share a transistor 31, which is used to drive the two third sub-light-emitting elements 003 in the same third light-emitting element 03 to emit light simultaneously. In other words, there is no need to design and manufacture a separate driving circuit for each third sub-light-emitting element 003, which can reduce the number of driving circuits, thereby reducing the number of components such as transistors 31 and capacitors in the display panel 100, reducing material costs and process complexity, and lowering production costs. Because the two third sub-light-emitting elements 003 share a pixel circuit, the area of ​​each third sub-light-emitting element 003 can be reduced. Accordingly, the film layer or substrate area occupied by each third sub-light-emitting element 003 can be reduced, achieving a higher pixel density and being applicable to high-resolution or micro display panels 100. In addition, the two third sub-light-emitting elements 003 are controlled by the same pixel circuit, which facilitates synchronous brightness or color calibration and improves the consistency of the overall light emission of the third light-emitting elements 03. In this way, by sharing the pixel circuit between the two third sub-light-emitting elements 003 in the same third light-emitting element 03, the circuit structure can be simplified, the manufacturing cost can be reduced, the space utilization can be optimized, and it is conducive to synchronous brightness or color calibration to improve the consistency of the overall light emission.

[0046] Please refer to Figure 4 The present disclosure provides a display panel 100, wherein the centers of the plurality of light-transmitting holes 00 are located on the same straight line L11 along a first direction D1; and / or, the centers of the plurality of light-transmitting holes 00 are located on the same straight line L12 along a second direction D2.

[0047] Specifically, in an optional embodiment provided by the present disclosure, along the first direction D1, the centers of the plurality of light-transmitting holes 00 are located on the same straight line L11; or, along the second direction D2, the centers of the plurality of light-transmitting holes 00 are located on the same straight line L12; or, along the first direction D1, the centers of the plurality of light-transmitting holes 00 are located on the same straight line L11, and, along the second direction D2, the centers of the plurality of light-transmitting holes 00 are located on the same straight line L12. As mentioned above, please combine Figure 5A third light-emitting element row 23 includes multiple third light-emitting elements 03, each of which is a blue light-emitting element. The centers of at least some of the blue light-emitting elements are aligned on a straight line L1, and the centers of at least some of the blue light-emitting elements are aligned on another straight line L2. A second light-emitting element column 12 includes multiple blue light-emitting elements arranged along a second direction D2, with light-transmitting holes 00 located between two adjacent blue light-emitting elements along the second direction D2. That is, the centers of all the blue light-emitting elements in a third light-emitting element row 23 are not aligned on the same straight line. However, the centers of the multiple light-transmitting holes 00 in the second display area AA2 are aligned on a straight line L11 along the first direction D1, and / or, the centers of the multiple light-transmitting holes 00 are aligned on a straight line L12 along the second direction D2. Because the light-transmitting holes 00 need to open on the display panel 100, arranging the centers of the light-transmitting holes 00 to be aligned on the same straight line facilitates pre-emptive positioning of certain horizontal or vertical signal lines in the display panel 100 around the light-transmitting holes 00, facilitating uniform design of the underlying film layers. During the manufacturing and assembly process, the linearly arranged light transmission holes 00 are also easier to accurately align and calibrate, thereby improving production efficiency and product consistency.

[0048] Figure 8 Shown Figure 1 A cross-section along the middle line A-A', please refer to Figure 8 The present disclosure provides a display panel 100, which includes an array layer 30, a pixel definition layer 40, a light-emitting layer 50, and a color filter layer 60. The pixel definition layer 40 is located on the side of the array layer 30 facing the light-emitting layer 50, and the color filter layer 60 is located on the side of the light-emitting layer 50 away from the array layer 30; the color filter layer 60 includes a light-shielding portion 61; the light-shielding portion 61 includes a first opening 62, the pixel definition layer 40 includes a second opening 41, and the projections of the first opening 62 and the second opening 41 in a direction perpendicular to the plane of the display panel 100 overlap; the light-transmitting hole 00 includes the first opening 62 and the second opening 41.

[0049] Specifically, the array layer 30 includes pixel circuits and control circuits. The pixel circuits and control circuits include multiple transistors 31 for driving the light-emitting elements to emit light. The pixel definition layer 40 is used to define the boundaries and light-emitting area of ​​each light-emitting element. The light-emitting layer 50 includes multiple light-emitting elements that emit light when current passes through them. Different light-emitting elements can emit different colors of light, such as red, green, and blue. The color filter layer 60 includes a light shielding portion 61, which is used to isolate light of different colors to prevent crosstalk and improve contrast and image clarity. In an optional embodiment provided by the present disclosure, the light-transmitting hole 00 includes a first opening 62 and a second opening 41. The first opening 62 is located in the light shielding portion 61 in the color filter layer 60, and the second opening 41 is located between two adjacent light-emitting elements in the pixel definition layer 40 along the first direction D1. The first opening 62 and the second opening 41 overlap in a direction perpendicular to the plane of the display panel 100. Together, they define a single channel for external light to enter the display panel 100, maximizing the effective light concentration and facilitating the reception of light by the light sensor within the display panel 100. Thus, by providing openings in the light shielding portion 61 in the color filter layer 60 and the pixel definition layer 40 , the functional synergy of each layer can be utilized to precisely control the incident path of external light and improve the light sensor's reception of external light.

[0050] Figure 9 Shown Figure 1 For another cross-sectional view along the middle line A-A', please refer to Figure 9 The present disclosure provides a display panel 100, wherein the light shielding portion 61 includes a black matrix; or, the light shielding portion 61 includes a first color resist 63 and a second color resist 64, the projections of the first color resist 63 and the second color resist 64 in a direction perpendicular to the plane of the display panel 100 overlap, and the first color resist 63 and the second color resist 64 have different colors.

[0051] Specifically, in an optional embodiment provided by the present disclosure, please refer to Figure 8 The light shielding portion 61 includes a black matrix, and the light-transmitting hole 00 includes a first opening 62 and a second opening 41. The first opening 62 is located in the black matrix of the color filter layer 60, and the second opening 41 is located in the pixel definition layer 40. The projections of the first opening 62 and the second opening 41 in the direction perpendicular to the plane of the display panel 100 overlap. In another optional embodiment provided by the present disclosure, please refer to Figure 9In the manufacturing process of the color filter layer 60, a first color resist 63 and a second color resist 64 of different colors overlapping along the second direction D2 are provided at the position of the light-shielding portion 61 to replace the black matrix. Specifically, when manufacturing the color filter layer 60, the black matrix process is eliminated and the color resist is directly applied. A stacked structure of two different color resists is used to replace the black matrix. For example, a half-tone mask is used to apply a normal thickness of color resist of the same color as the corresponding light-emitting element in the light-emitting element opening area, and a thinned color resist is applied to the original black matrix areas on both sides of the light-emitting element opening area. The red color resist can be applied first, and then the green color resist. By stacking two layers of different color resists, the black shielding effect is basically achieved. It can be understood that the coating order of the different color resists can be set according to actual production needs, and this disclosure is not limited to this. In this way, the first opening 62 of the light-transmitting hole 00 can be set in the black matrix of the color film layer 60 according to the manufacturing process of the black matrix, or can be set in the stacking structure of different color resists that replace the black matrix according to the manufacturing process of stacking different color resists. Of course, the first opening 62 of the light-transmitting hole 00 can also be set in other light-shielding structures that replace the black matrix, which is not disclosed and not limited to this.

[0052] Please refer to Figures 2 to 6 The present disclosure provides a display panel 100 , in which, in a plan view, edges of the first light-emitting element 01 , the second light-emitting element 02 , and the third light-emitting element 03 all include curved edges.

[0053] Optionally, the first light-emitting element 01, the second light-emitting element 02 and the third light-emitting element 03 include circular, elliptical, 8-shaped and other shapes with curved edges. The present disclosure does not limit the shape of the light-emitting element, and it is only necessary that its edge include a curved edge. The curved edge can make the boundary transition of the light-emitting element smoother and more natural, so that the light emitted by the light-emitting element can be diffused and transitioned more naturally at the edge, reducing obvious light boundaries, helping to improve the uniformity of the light, reducing brightness attenuation or color shift at specific angles, providing a wider viewing angle, and improving the visual softness of the overall picture. In this way, by setting the edge of the light-emitting element to include a curved edge, the light transition at the edge of the light-emitting element can be improved, thereby enhancing the user's visual experience.

[0054] In addition, considering the color shift symmetry and dispersion issues, the shapes of the first light-emitting element 01, the second light-emitting element 02 and the third light-emitting element 03 in the embodiment of the present disclosure can be symmetrical.
