Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a display panel and electronic equipment. BACKGROUND

[0002] With the development of display technology, people not only require smooth use experience of electronic products, but also have higher and higher requirements on visual experience, and high screen ratio has become the research direction at present. For electronic products, the setting of optical elements such as front camera will inevitably occupy a certain space, thereby affecting the screen ratio. In order to improve the screen ratio and realize full-screen, researchers consider the implementation scheme of under-screen optical element.

[0003] The optical element is arranged below the film layer where the light emitting device of the display panel is located, that is, the optical element is arranged in the display area. When display is needed, the position where the optical element is located can be normally displayed; when the optical element is needed to be used, light rays penetrate the display panel to reach the optical element and are finally utilized by the optical element. The optical element is arranged under the screen, and the light rays need to penetrate the film layer structure of the display panel to be utilized by the optical element. It is found through evaluation of the current under-screen optical element setting scheme that the imaging of the under-screen optical element is very blurred, which is difficult to meet the needs of users. SUMMARY

[0004] Therefore, the present application provides a display panel and electronic equipment, which improves the imaging quality of light rays after penetrating the display panel, so as to improve the optical effect of the under-screen optical element.

[0005] In a first aspect, the present application provides a display panel, the display area of the display panel is divided into at least two pixel areas, the pixel area includes at least two sub-pixels, the display area includes a first display area and a second display area, the sub-pixel density of the first display area is less than the sub-pixel density of the second display area; wherein in the first display area, the structures of at least part of two adjacent pixel areas are different.

[0006] The display panel provided in the present application has a first display area with a sub-pixel density less than that of a second display area. When the display panel is assembled into a display device, an optical element can be arranged below the position corresponding to the first display area, such as one or more of a camera, an optical fingerprint sensor, a structured light emitter, a structured light receiver, a proximity light emitter, a proximity light receiver, and a time of flight (TOF) device. By arranging the sub-pixel density of the first display area to be less than that of the second display area, the light transmittance of the first display area can be improved, thereby increasing the amount of light received by the under-screen optical element. In the display panel provided in the present application, the structures of some adjacent pixel areas in the first display area can be different, or the structures of all adjacent pixel areas (i.e., any adjacent pixel areas) in the first display area can be different. Compared with the related art in which the same structure is arranged in multiple pixel areas in a display area, the present application can change the regularity of the arrangement of pixel areas in the first display area to some extent, thereby weakening the diffraction phenomenon of light penetrating through the display panel, and further improving the optical effect of the under-screen optical element.

[0045] In order to better understand the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the drawings.

[0046] It should be clear that the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0047] The terms used in the embodiments of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0048] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0049] It should be understood that although the terms first, second, etc. may be used in the embodiments of the present application to describe the devices, these devices should not be limited to these terms. These terms are only used to distinguish the devices from each other. For example, without departing from the scope of the embodiments of the present application, the first device can also be called the second device, and similarly, the second device can also be called the first device.

[0050] In related display technologies, an optical element is arranged below a display panel and in a display area, that is, a pixel is still arranged above the optical element corresponding to the optical element. When display is needed, the position where the optical element is located can normally display; when the function of the optical element is turned on, the light penetrates the display panel and is used by the optical element. The scheme of realizing the under-screen optical element can be beneficial to improve the screen ratio. The inventors find that in the current scheme of the under-screen optical element, obvious diffraction phenomenon occurs when the light penetrates the display panel, and the diffraction light seriously affects the optical performance of the optical element. Taking the optical element as a camera as an example, the main function of the under-screen camera is to take pictures or make videos, and the image clarity of the image formed by the camera using the diffraction light is very poor, which seriously affects the shooting effect of the camera.

[0051] The optical element is arranged below the display area of the display panel, and the light needs to penetrate the display layer and the array layer of the display panel before being used by the optical element. When the light penetrates the display panel, the arranged plurality of light emitting devices in the display layer and the pixel circuit and the signal line in the array layer all act as a diffraction grating, and diffraction phenomenon occurs when the light penetrates. In related technologies, in order to reduce the difficulty of the manufacturing process, the same structure of pixels is used to manufacture in the entire panel, that is, the same structure of pixels is arranged in an array in the display area. The pixel circuit in the array layer is also arranged in an array. The inventors believe through a large number of experimental researches and thinking that: the display area in related technologies acts as a short-period regular diffraction grating with a pixel as a period, and forms short-period regular stripe diffraction when the light penetrates the display panel, which seriously affects the optical performance of the optical element.

[0052] Based on this, the present application provides a display panel and an electronic device, in the display area corresponding to the optical element (that is, the first display area in the present application), the structures of at least part of two adjacent pixel areas are different, the shapes of the light transmission areas of at least part of the two adjacent pixel areas are different, that is, by changing the structures of at least part of the two adjacent pixel areas, the arrangement regularity of the pixel areas in the first display area is changed to a certain extent, the at least part of the short-period regular diffraction grating is broken, the period length of the grating is increased or the grating without period is formed, the diffraction phenomenon caused when the light penetrates the display panel is weakened, and then the optical effect of the under-screen optical element is improved.

[0053] Figure 1 An optional embodiment of the display panel provided by the present application is shown in the schematic diagram. Figure 2 For Figure 1 A local enlarged view of the position Q1. Figure 3 Another optional embodiment of the display panel provided by the present application is shown in the schematic diagram. Figure 4 A local schematic diagram of the display panel in related technologies.

[0054] As shown in Figure 1 , the display area AA includes a first display area AA1 and a second display area AA2, the sub-pixel density of the first display area AA1 is less than that of the second display area AA2, and the sub-pixel density refers to the number of sub-pixels per unit area. When the display panel is assembled into an electronic device, an optical element can be arranged below the position corresponding to the first display area AA1, which can be one or more of a camera, an optical fingerprint sensor, a structured light emitter, a structured light receiver, a proximity light emitter, a proximity light receiver, and a time of flight (TOF) device. By setting the sub-pixel density of the first display area AA1 to be less than that of the second display area AA2, the light transmittance of the first display area AA1 can be improved, thereby increasing the amount of light received by the under-screen optical element. The shape of the first display area AA1 is not limited in the embodiments of the present application, and the shape of the first display area AA1 can be circular, semicircular, triangular, rectangular, or any polygon. The relative positional relationship between the first display area AA1 and the second display area AA2 is also not limited. Figure 1 Only the second display area AA2 surrounds the first display area AA1 is shown, as Figure 3 indicated, the second display area AA2 can also semi-enclose the first display area AA1.

[0055] As shown in Figure 2 , the display area AA of the display panel is divided into a plurality of pixel areas P, and each pixel area P includes at least two sub-pixels sp. In the figure, one pixel area P includes a red light emitting sub-pixel spR, a blue light emitting sub-pixel spB, and a green light emitting sub-pixel spG, a total of three sub-pixels are shown, and optionally, one pixel area P can also include a white light emitting sub-pixel, or one pixel area can only include two sub-pixels of different colors, which is not shown in the figure. It can be seen that Figure 2 It can be seen that the sub-pixel density of the first display area AA1 is less than that of the second display area AA2.

[0056] It should be noted that the pixel area in the embodiments of the present application refers to an area formed by a plurality of adjacent sub-pixels and the structures around them. In one embodiment, one pixel area includes two sub-pixels; in another embodiment, one pixel area includes three sub-pixels; and in another embodiment, one pixel area can also include four sub-pixels. In the embodiments of the present application, one pixel area is shown to include three sub-pixels, and for other cases, it can be understood by analogy.

[0057] In the first display area AA1, the structures of at least two adjacent pixel areas P are different. The structure in the present application includes but is not limited to the arrangement structure of the light-emitting areas of the sub-pixels in the pixel area, the composition structure of the pixel area, and the arrangement structure of the signal lines in the pixel area. The arrangement structure of the light-emitting areas of the sub-pixels includes at least one of the interval distance between the light-emitting areas of the sub-pixels, the inclination angle of the light-emitting areas of the sub-pixels relative to the same edge of the display panel, the shape of the light-emitting areas of the sub-pixels, and the area size of the light-emitting areas of the sub-pixels. The composition structure of the pixel area can be that the pixel area includes other structures such as light-shielding structures in addition to the sub-pixels. Figure 2 In the structure shown in the middle, the structures are different only in the inclination angle of the light-emitting areas of the sub-pixels relative to the same edge of the display panel.

[0058] It should be noted that the display panel provided in the present application can be an organic light-emitting display panel, and the display panel includes a substrate, an array layer, and a display layer stacked in sequence. The display layer includes a plurality of organic light-emitting devices, and each organic light-emitting device includes an anode, a light-emitting layer, and a cathode. The plurality of organic light-emitting devices includes at least a light-emitting device configured to emit red light, a light-emitting device configured to emit green light, and a light-emitting device configured to emit blue light, and one organic light-emitting device corresponds to one sub-pixel. During display, after a voltage is applied to the anode and the cathode, the light-emitting layer is excited to emit light, thereby realizing the light emission of the sub-pixel. Therefore, the shape and size of the light-emitting area of the sub-pixel generally correspond to the shape and size of the light-emitting layer. It is continued to refer to Figure 2 It is shown that the pixel area includes a plurality of light-emitting areas G and non-light-emitting areas FG, wherein the light-emitting area G is the light-emitting region of the sub-pixel sp, Figure 2 In the structure shown in the middle, the structures are different only in the inclination angle of the light-emitting areas of the sub-pixels relative to the same edge of the display panel.

[0058] It should be noted that the display panel provided in the present application can be an organic light-emitting display panel, and the display panel includes a substrate, an array layer, and a display layer stacked in sequence. The display layer includes a plurality of organic light-emitting devices, and each organic light-emitting device includes an anode, a light-emitting layer, and a cathode. The plurality of organic light-emitting devices includes at least a light-emitting device configured to emit red light, a light-emitting device configured to emit green light, and a light-emitting device configured to emit blue light, and one organic light-emitting device corresponds to one sub-pixel. During display, after a voltage is applied to the anode and the cathode, the light-emitting layer is excited to emit light, thereby realizing the light emission of the sub-pixel. Therefore, the shape and size of the light-emitting area of the sub-pixel generally correspond to the shape and size of the light-emitting layer. It is continued to refer to Figure 2

[0059] As Figure 4 The design of the display panel in the related art is shown by taking part of the display area AA1' and the display area AA2' as an example. The sub-pixel density of the display area AA1' is less than that of the display area AA2'. The pixel regions P' in the display area AA1' are arranged regularly, and each pixel region P' has the same structure. One pixel region P' includes a red light emitting sub-pixel spR', a blue light emitting sub-pixel spB', and a green light emitting sub-pixel spG'. The inventors believe that each pixel region P' in the related art corresponds to a diffraction grating. Since each pixel region P' has the same structure, the wiring arrangement in the non-light emitting area FG' corresponding to each pixel region P' is also roughly the same. When Figure 4 When the display panel in the related art is applied in the under-screen optical element scheme, it is equivalent to forming a short period regular diffraction grating with one pixel region P' as a period, and forming a short period regular stripe diffraction when the light penetrates the display panel, which seriously affects the optical performance of the optical element.

[0060] Continuing to refer to Figure 2 As an example, the first direction x and the second direction y perpendicular to each other are shown, the display panel includes an edge with the extension direction being the second direction y (a local schematic diagram is shown in the figure, and the edge of the display panel is not shown), and the sub-pixels are all strip structures. The three sub-pixels sp in the pixel region P1 are all inclined at a certain angle with respect to the second direction y, and the three sub-pixels sp in the pixel region P2 adjacent to the pixel region P1 in the second direction y are roughly not inclined with respect to the second direction y. The structures of the pixel region P1 and the pixel region P2 adjacent to each other in the second direction y are different. The three sub-pixels sp in the pixel region P3 are also inclined at a certain angle with respect to the second direction y. However, the inclination direction of the three sub-pixels sp in the pixel region P3 with respect to the second direction y is opposite to that of the three sub-pixels sp in the pixel region P1 with respect to the second direction y. Therefore, the structure of the pixel region P3 is different from that of the pixel region P1. As shown in the figure, there is no interval pixel region P between the pixel region P3 and the pixel region P1. Therefore, the pixel region P3 and the pixel region P1 also belong to two adjacent pixel regions with different structures. Similarly, the pixel region P2 and the pixel region P3 also belong to two adjacent pixel regions with different structures. As Figure 2For example, the structures of the pixel region P1 and the pixel region P2 are different, and the shapes of the non-light-emitting regions FG corresponding to the pixel region P1 and the pixel region P2 are changed, and the lengths or the number of the exposed wirings in the non-light-emitting regions FG are also changed, so that the shapes of the light-transmitting regions in the non-light-emitting regions FG are changed. The pixel region P1 and the pixel region P2 form two different diffraction gratings, so that the display panel provided in the present application does not use one pixel region as the period of the diffraction grating, and the rule of the short-period diffraction grating with one pixel region as the period is broken.

[0061] The display panel provided in the present application has different structures of at least part of the adjacent pixel regions in the first display region, and the arrangement regularity of the structures of the pixel regions in the first display region is changed by changing the structures of at least part of the pixel regions, so that the rule of the short-period diffraction grating with one pixel region as the period is broken. The structures of the pixel regions in the first display region can be designed to increase the period length of the diffraction grating, or the structures of the pixel regions in the first display region can be designed to realize the diffraction grating without period, so that the diffraction phenomenon caused by the light penetrating the display panel is improved, and the optical effect of the under-screen optical element is improved. In addition, the display panel provided in the present application only needs to design the structures of at least part of the pixel regions in the first display region, and the sub-pixel density in the first display region is not affected.

[0062] It should be noted that, Figure 2 Only the case that the structures of part of the adjacent two pixel regions P are different is shown. Alternatively, the structures of any two adjacent pixel regions P can be different, and in this case, the structures of the pixel regions that are not adjacent can be the same, which will be described in detail in the following specific embodiments.

[0063] Figure 5 A local schematic view of a film layer structure of an optional embodiment of the display panel provided in the present application is shown in FIG. 6. As shown in FIG. 6, the structures of the pixel region P1 and the pixel region P2 are different, and the shapes of the non-light-emitting regions FG corresponding to the pixel region P1 and the pixel region P2 are changed, and the lengths or the number of the exposed wirings in the non-light-emitting regions FG are also changed, so that the shapes of the light-transmitting regions in the non-light-emitting regions FG are changed. The pixel region P1 and the pixel region P2 form two different diffraction gratings, so that the display panel provided in the present application does not use one pixel region as the period of the diffraction grating, and the rule of the short-period diffraction grating with one pixel region as the period is broken. Figure 5As shown, the display panel includes a substrate 101, an array layer 102, and a display layer 103. The display layer 103 includes organic light emitting devices J, each of which includes an anode a, a light emitting layer b, and a cathode c. The organic light emitting devices J include at least light emitting devices configured to emit red light, light emitting devices configured to emit green light, and light emitting devices configured to emit blue light, which are not distinguished in the figure. Optionally, the organic light emitting devices J further include at least one of a hole transport layer, an electron transport layer, a hole injection layer, and an electron injection layer, which are not shown in the figure. The display layer 103 further includes a pixel definition layer PDL, which includes a plurality of openings K, one opening K corresponding to one organic light emitting device J, and is used to separate the organic light emitting devices J. The array layer 102 includes a plurality of pixel circuits, each of which is electrically connected to the anode a of an organic light emitting device J, and only one transistor T in the pixel circuit is shown in the figure. The transistor T is shown in a top-gate structure, and can alternatively be in a bottom-gate structure, which is not shown in the figure. An encapsulation structure 104 is further provided on the display layer 103, and is used to block water and oxygen to prevent the organic light emitting devices J from being damaged by water and oxygen, and to ensure the service life of the organic light emitting devices J. The encapsulation structure 104 can be a thin film encapsulation, which includes at least one organic layer and at least one inorganic layer.

[0064] The display panel provided by the embodiments of the present application can be manufactured by the following method: first, a substrate 101 is manufactured; then, an array layer 102 is manufactured on the substrate 101, wherein the array layer 102 includes at least a semiconductor active layer, a gate metal layer, a source / drain metal layer, and an insulating layer between the metal layers. The array layer 102 is manufactured by using the process in the prior art. For example, the active layer, the gate, and the source and drain electrodes in the transistor T are sequentially manufactured by using the process of coating-glazing-exposing-developing-etching. After the source and drain electrodes of the transistor are manufactured, an insulating layer C1 is manufactured, which can be a planarization layer. The insulating layer C1 is etched to form a via O exposing the drain electrode, and then the anode a of the organic light emitting device is manufactured on the insulating layer C1, which is also manufactured by etching, and the anode a is electrically connected to the drain electrode of the transistor T through the via O; then, a pixel definition layer PDL is manufactured on the anode a, and the pixel definition layer PDL is etched to form an opening K exposing the anode. The light emitting layer b and other organic film layers are manufactured by using the evaporation process, wherein when the light emitting layer b is evaporated, the openings K corresponding to the light emitting devices emitting the same color light are evaporated by using the same mask plate. The hole transport layer and other organic film layers in the organic light emitting device are also manufactured by using the evaporation process. After the organic layer is evaporated, a cathode layer is generally laid in an integral layer.

[0065] In an embodiment, in the display panel provided by the embodiments of the present application, in the second display area, the structures of two adjacent pixel areas are the same. For the sake of continuity, reference will be made to Figure 2 As shown in the partial region of the second display area AA2, in the second display area AA2, the structures of two adjacent pixel areas P are the same. That is, in the second display area AA2, the pixel areas are still arranged periodically with one pixel area as a period. In this embodiment, only the structure of the pixel area in the first display area AAl is changed, and the structure of the pixel area in the second display area AA2 is not changed. The sub-pixel density in the first display area is reduced, and the structures of at least part of two adjacent pixel areas in the first display area are different, so as to improve the light transmittance of the first display area, and break the arrangement rule of one pixel area as a period in at least part of the region. The display panel provided by the embodiments can increase the amount of light received by the optical element when applied to the under-screen optical element scheme, and can improve the diffraction phenomenon of the light penetrating the display panel, and improve the optical performance of the optical element.

[0066] In the display panel provided by the embodiments of the present application, when the structures of two adjacent pixel areas are different by changing the arrangement structure of the light-emitting area of the sub-pixel in the first display area, the mask plate used in the anode etching process and the mask plate used in the etching process of the pixel definition layer can be adjusted accordingly. After the two kinds of mask plates are adjusted and designed, the arrangement structure of the light-emitting area of the sub-pixel in the pixel area can be changed, so that any one of the interval distance between the light-emitting areas of the sub-pixels, the inclination angle of the light-emitting area of the sub-pixel relative to the same edge of the display panel, the shape of the light-emitting area of the sub-pixel, or the area size of the light-emitting area of the sub-pixel can be adjusted, so as to realize the different structures of two adjacent pixel areas. When the structures of two adjacent pixel areas are different by changing the composition structure of the pixel area in the first display area, a new structure can be added by adding a corresponding process in the above-described manufacturing process, or the shape of the existing part of the film layer structure can be changed by designing the mask plate. When the structures of two adjacent pixel areas are different by changing the arrangement structure of the signal line in the pixel area in the first display area, the mask plate used in the signal line manufacturing process can be designed.

[0067] In some optional embodiments, the display panel provided by the embodiments of the present application, the pixel region includes a light-emitting region, one sub-pixel corresponds to one light-emitting region, and in the two adjacent pixel regions with different structures: the arrangement structures of the light-emitting regions of the sub-pixels are different. By adjusting the arrangement structures of the light-emitting regions of the sub-pixels, the structures of the two adjacent pixel regions are realized to be different. When the arrangement structures of the light-emitting regions of the sub-pixels in the pixel region change, the shape of the non-light-emitting region corresponding to the pixel region changes, and the number or length of the traces of the array layer corresponding to the non-light-emitting region also changes accordingly, thereby breaking the rule of the short-period diffraction grating with one pixel region as a period, improving the diffraction phenomenon caused by the light penetrating the display panel, and improving the optical effect of the under-screen optical element.

[0068] Optionally, in the display panel provided by the embodiments of the present application, the arrangement structures of the light-emitting regions of the sub-pixels are different, including at least one of the following: the interval distances between the two adjacent light-emitting regions are different, the inclination angles of the light-emitting regions relative to the same edge of the display panel are different, the shapes of the light-emitting regions are different, the area sizes of the light-emitting regions are different, and the relative positions of the light-emitting regions are different. For the specific implementation of realizing the structures of the two adjacent pixel regions to be different by adjusting the arrangement structures of the light-emitting regions of the sub-pixels, examples will be given in the following embodiments.

[0069] In an embodiment, by adjusting the interval distances between the two adjacent light-emitting regions in the pixel region, the arrangement structures of the light-emitting regions of the sub-pixels in the pixel region are adjusted, and the structures of the two adjacent pixel regions are realized to be different. Figure 6 An optional embodiment of a partial top view schematic diagram of the first display region of the display panel provided by the embodiments of the present application. As shown in FIG. 1, the display panel 100 includes a first display region 110 and a second display region 120. The first display region 110 includes a plurality of pixel regions 111, and the second display region 120 includes a plurality of pixel regions 121. Figure 6As shown, the pixel region includes a light emitting region G, and one sub-pixel sp corresponds to one light emitting region G. The sub-pixel sp is shown in the form of the shape of the light emitting region G. It is shown that one pixel region P includes three sub-pixels sp1, sp2 and sp3, and the sub-pixels sp1, sp2 and sp3 emit light of different colors respectively. It is shown that the three sub-pixels in the pixel region are arranged in the first direction x, and the three sub-pixels are all in the form of a strip structure. The interval distance between the light emitting regions G of two sub-pixels in one pixel region is the interval distance of the light emitting regions G of the two sub-pixels in the first direction x. In the pixel region P4: the interval distance between the light emitting region G of the sub-pixel sp1 and the light emitting region G of the sub-pixel sp2 is L1, and the interval distance between the light emitting region G of the sub-pixel sp2 and the light emitting region G of the sub-pixel sp3 is L2; in the pixel region P5: the interval distance between the light emitting region G of the sub-pixel sp1 and the light emitting region G of the sub-pixel sp2 is L1', and the interval distance between the light emitting region G of the sub-pixel sp2 and the light emitting region G of the sub-pixel sp3 is L2'; wherein L1≠L1', and L2≠L2', and the arrangement structures of the sub-pixels of the adjacent pixel regions P4 and P5 are different. Optionally, in this embodiment, L1 and L2 can be equal or not equal. Similarly, L1' and L2' can be equal or not equal. The pixel region P4 shown in the figure is adjacent to the pixel region P5 in the first direction x and in the second direction y.

[0070] Figure 6 The corresponding embodiments show that, in the adjacent two pixel regions, by setting the interval distances between the adjacent two light emitting regions in a pixel region to be different, the arrangement structures of the light emitting regions of the sub-pixels of the adjacent two pixel regions are different, so that the structures of the adjacent two pixel regions are different, the rule of the short period diffraction grating with one pixel region as a period is broken, and the diffraction phenomenon when light penetrates through the display panel is improved. Taking one pixel region including three sub-pixels as an example, as shown in the figure, the three sub-pixels sp are arranged in the first direction x in turn, so that in one pixel region, the interval distances between the adjacent two light emitting regions include at least two, i.e., the interval distance between the light emitting region G of the sub-pixel sp1 and the light emitting region G of the sub-pixel sp2, and the interval distance between the light emitting region G of the sub-pixel sp2 and the light emitting region G of the sub-pixel sp3. Figure 6 Figure 6 In the embodiments, it is shown that in the adjacent two pixel regions, the corresponding two interval distances are different. In another implementation, in the adjacent two pixel regions, one interval distance is different, and the other interval distance is the same. For example: in the adjacent two pixel regions: the interval distance between the light emitting region G of the sub-pixel sp1 and the light emitting region G of the sub-pixel sp2 is different, and the interval distance between the light emitting region G of the sub-pixel sp2 and the light emitting region G of the sub-pixel sp3 is the same.

[0071] ​In one embodiment, the arrangement structure of the light-emitting areas of the sub-pixels within a pixel region is adjusted by adjusting the tilt angle of the light-emitting areas of the sub-pixels within the pixel region relative to the same edge of the display panel, thereby achieving different structures for two adjacent pixel regions. Figure 7 This is a partial top view schematic diagram of another optional embodiment of the first display area of ​​the display panel provided in the embodiments of this application. (See attached diagram.) Figure 7 As shown, the shape of the light-emitting area G is used to represent the sub-pixel sp. A pixel area is represented by three sub-pixels sp1, sp2, and sp3, each of which is a strip-shaped structure. The direction of extension of one edge of the display panel is shown in the diagram. Figure 7 Taking the first direction x as an example (the figure is a partial schematic diagram and the edge of the display panel is not shown). In the figure, the tilt angle of the light-emitting area G of the sub-pixel in pixel area P6 relative to the first direction x is α1, and the tilt angle of the light-emitting area G of the sub-pixel in pixel area P7 relative to the first direction x is β1. Here, α1 ≠ β1, meaning that the tilt angles of the light-emitting areas in adjacent pixel areas P6 and P7 relative to the same edge of the display panel are different, thus the arrangement structure of the sub-pixels in adjacent pixel areas P6 and P7 is different. In this embodiment, optionally, β1 = 90°.

[0072] In one embodiment, Figure 8 This is a partial top view schematic diagram of another optional embodiment of the first display area of ​​the display panel provided in the embodiments of this application. (See attached diagram.) Figure 8 As shown, the shape of the light-emitting area G is used to represent the sub-pixel sp. A pixel area is represented by three sub-pixels sp1, sp2, and sp3, each of which is a strip-shaped structure. The direction of extension of one edge of the display panel is shown in the diagram. Figure 8 Taking the first direction x as an example, the tilt angle of the light-emitting area G of the sub-pixel in pixel area P8 relative to the first direction x is α2, and the tilt angle of the light-emitting area G of the sub-pixel in pixel area P9 relative to the first direction x is β2. Where α2 ≠ β2, that is, the tilt angles of the light-emitting areas in adjacent pixel areas P8 and P9 relative to the same edge of the display panel are different, so the arrangement structure of the sub-pixels in adjacent pixel areas P8 and P9 is different.

[0073] Figure 7 and Figure 8 The corresponding embodiment illustrates that by adjusting the tilt angle of the light-emitting area in two adjacent pixel areas relative to the same edge of the display panel, the arrangement structure of the light-emitting area of ​​the sub-pixels in two adjacent pixel areas is different, thereby achieving different structures in two adjacent pixel areas. Figure 7 and Figure 8In some alternative embodiments, in the two adjacent pixel regions with different structures, the inclination angles of the light emitting regions of all the sub-pixels in the same pixel region relative to the same edge of the display panel are not completely the same.

[0074] In an embodiment, the arrangement structure of the light emitting regions of the sub-pixels in a pixel region is adjusted by adjusting the shapes of the light emitting regions of the sub-pixels in the pixel region, so as to realize the different structures of the two adjacent pixel regions. Figure 9 Another alternative embodiment of the first display region of the display panel provided in the embodiments of the present application is schematically shown in a partial top view. As shown in Figure 9 The sub-pixels sp are schematically shown by the shapes of the light emitting regions G, and one pixel region includes three sub-pixels sp1, sp2 and sp3. For example, the three sub-pixels in a pixel region are arranged in a triangle, and the three sub-pixels sp1, sp2 and sp3 occupy the three vertices of the triangle, respectively. The shapes of the light emitting regions G of the corresponding sub-pixels sp1, the shapes of the light emitting regions G of the corresponding sub-pixels sp2 and the shapes of the light emitting regions G of the corresponding sub-pixels sp3 in the pixel region P10 and the pixel region P11 are all different, and the arrangement structures of the sub-pixels of the adjacent pixel region P10 and the pixel region P11 are different.

[0075] It should be noted that, Figure 9 In the embodiments, the same pattern represents the same sub-pixel, and the same sub-pixel is not represented by the same shape. Moreover, Figure 9 The shapes of the sub-pixels are only schematically shown and do not limit the embodiments of the present application. In the embodiment in which the arrangement structure of the light emitting regions of the sub-pixels is adjusted by adjusting the shapes of the light emitting regions in a pixel region, the shape of the sub-pixel can be designed according to the specific design needs and process needs.

[0076] Figure 9 The corresponding embodiments show that in the two adjacent pixel regions, the shapes of the light emitting regions of the corresponding sub-pixels are all different, so as to realize the different structures of the two pixel regions. In another embodiment, in the two adjacent pixel regions, the shapes of the light emitting regions of the corresponding part of the sub-pixels are different, and the shapes of the light emitting regions of the remaining corresponding sub-pixels are the same. For example, Figure 9 For example, in a pixel region, the three sub-pixels are arranged in a triangle. In the two adjacent pixel regions, the shapes of the light emitting regions of the corresponding sub-pixels sp1 are different, the shapes of the light emitting regions of the corresponding sub-pixels sp2 are different, and the shapes of the light emitting regions of the corresponding sub-pixels sp3 are the same.

[0077] In an embodiment, in two adjacent pixel regions with different structures: the shapes of all the sub-pixels belonging to the same pixel region can be all the same or partially the same, which is not shown in the figure.

[0078] In an embodiment, the arrangement of the light-emitting areas of the sub-pixels in a pixel region is adjusted by adjusting the sizes of the light-emitting areas of the sub-pixels in the pixel region, so as to realize the different structures of two adjacent pixel regions. Figure 10 Another optional embodiment of the first display region of the display panel provided in the embodiment of the present application is shown in a partial top view. Figure 10 As shown in the figure, the sub-pixels sp are shown by the shapes of the light-emitting areas G, and one pixel region includes three sub-pixels sp1, sp2 and sp3. The areas of the light-emitting areas G of the three sub-pixels in the pixel region P12 are all larger than the areas of the light-emitting areas G of the three sub-pixels in the pixel region P13. The arrangement of the sub-pixels in the adjacent pixel regions P12 and P13 is different. It should be noted that, Figure 10 The arrangement of the light-emitting areas of the sub-pixels in the pixel region is only shown schematically and is not a limitation on the present application. The embodiment of adjusting the arrangement of the sub-pixels by adjusting the sizes of the light-emitting areas of the sub-pixels in the pixel region is applicable to any arrangement of the sub-pixels that can be realized.

[0079] Figure 10 It is shown that in two adjacent pixel regions: the areas of the light-emitting areas of the three sub-pixels in one pixel region are all larger than the areas of the light-emitting areas of the corresponding three sub-pixels in the other pixel region.

[0080] In another embodiment, in two adjacent pixel regions with different structures: the areas of the light-emitting areas of two sub-pixels are the same, and the area of the light-emitting area of one sub-pixel is different.

[0081] In another embodiment, in two adjacent pixel regions with different structures: the areas of the light-emitting areas of one sub-pixel are the same, and the areas of the light-emitting areas of two sub-pixels are different.

[0082] In an embodiment, Figure 11 Another optional embodiment of the first display region of the display panel provided in the embodiment of the present application is shown in a partial top view. Figure 11As shown, the shape of the light-emitting area G is used to illustrate the sub-pixel sp, and a pixel region is illustrated by including three sub-pixels sp1, sp2, and sp3. The shapes of the light-emitting areas G for corresponding sub-pixels sp1, sp2, and sp3 in pixel regions P14 and P15 are all different. Furthermore, the spacing between adjacent light-emitting areas in pixel regions P14 and P15 is also different. The arrangement structure of the sub-pixel light-emitting areas in pixel regions P14 and P15 is different. This embodiment adjusts the arrangement structure of the sub-pixel light-emitting areas by simultaneously adjusting the spacing between adjacent light-emitting areas and the shape of the light-emitting areas, thus achieving different structures for adjacent pixel regions.

[0083] In one embodiment, Figure 12 This is a partial top view schematic diagram of another optional embodiment of the first display area of ​​the display panel provided in the embodiments of this application. (See attached diagram.) Figure 12 As shown, the shape of the luminous area G is used to represent the sub-pixel sp, and a pixel region is illustrated by comprising three sub-pixels sp1, sp2, and sp3. The luminous areas G of corresponding sub-pixels sp1 in pixel regions P43 and P44 have the same shape (illustrated as circular luminous areas in the figure), but the relative positions of adjacent luminous areas G are different. This achieves different arrangement structures of the sub-pixel luminous areas in pixel regions P43 and P44. This embodiment adjusts the arrangement structure of the luminous areas of the sub-pixels by adjusting the relative positions of two adjacent luminous areas, thus achieving different structures for adjacent pixel regions.

[0084] It should be noted that, without conflict, embodiments of this application may employ one or more of the following methods to adjust the arrangement structure of the light-emitting areas of sub-pixels within a pixel: adjusting the spacing between two adjacent light-emitting areas, adjusting the tilt angle of the light-emitting area relative to the same edge of the display panel, adjusting the shape of the light-emitting area, adjusting the area size of the light-emitting area, and adjusting the relative position of two adjacent light-emitting areas, thereby achieving different structures for two adjacent pixel areas.

[0085] In some optional embodiments, the display panel provided in the embodiments of the present application is different in structure in two adjacent pixel regions, wherein: at least one pixel region comprises a light shielding structure; the pixel region comprises a light emitting region and a non-light emitting region, one sub-pixel corresponds to one light emitting region, the non-light emitting region surrounds the light emitting region, and the light shielding structure overlaps the non-light emitting region. In the first display region, the light shielding structure can shield light penetrating through the display panel, and the light shielding structure overlaps the non-light emitting region, so that the setting of the light shielding structure in the pixel region can change the shape of the light transmission region in the non-light emitting region corresponding to the pixel region, thereby changing the shape of the diffraction grating formed by the pixel region, and different diffraction gratings are formed by the two adjacent pixel regions. In turn, the regularity of the short-period diffraction grating with one pixel region as a period can be broken, the diffraction phenomenon caused by the light penetrating through the display panel can be improved, and the optical effect of the under-screen optical element can be improved.

[0086] In an embodiment, Figure 13 Another optional embodiment of the first display region of the display panel provided in the embodiments of the present application is a partial top view. As shown in Figure 13 The pixel region comprises at least two light emitting regions G and a non-light emitting region FG surrounding the light emitting regions G, and one pixel region comprises three sub-pixels sp1, sp2 and sp3. In addition to the three sub-pixels corresponding light emitting regions G, one pixel region also comprises a non-light emitting region FG surrounding the light emitting regions G. The pixel region P16 comprises a light shielding structure Z, and the light shielding structure Z overlaps the non-light emitting region FG. In the top view, it can be seen that the light shielding structure Z is located in the non-light emitting region FG. The light shielding structure Z can shield light, change the shape of the light transmission region in the non-light emitting region FG corresponding to the pixel region P16, and change the shape of the diffraction grating formed by the pixel region P16. The pixel region P17 adjacent to the pixel region P16 does not comprise a light shielding structure, the structures of the pixel region P16 and the pixel region P17 are different, the shapes of the diffraction gratings formed by the pixel region P16 and the pixel region P17 are different, the regularity of the short-period diffraction grating with one pixel region as a period can be broken, and the diffraction phenomenon caused by the light penetrating through the display panel can be improved.

[0087] Figure 13 Only one setting mode of the light shielding structure is shown in the embodiment, and in another embodiment, as shown in Figure 14 , Figure 14 Another optional embodiment of the first display region of the display panel provided in the embodiments of the present application is a partial top view. The pixel region P18 comprises a light shielding structure Z, and the light shielding structure Z overlaps the non-light emitting region FG. The pixel region P19 adjacent to the pixel region P18 does not comprise a light shielding structure, so the structures of the pixel region P18 and the pixel region P19 are different. In this embodiment, the shape of the light shielding structure Z and the relative position of the light shielding structure Z and the sub-pixel sp are the same as those in the embodiment of the display panel provided in the embodiments of the present application. Figure 13They are different. The light-blocking structure Z overlaps with the non-emitting area FG. The shape of the light-blocking structure Z and its relative position with the sub-pixel will affect the shape of the light-transmitting area within the non-emitting area FG, thereby affecting the shape of the diffraction grating formed by the pixel area corresponding to the non-emitting area FG.

[0088] It should be noted that, Figure 13 and Figure 14 The arrangement of sub-pixels within the pixel area is for illustrative purposes only. The display panel provided in this application does not limit the size of the light-shielding structure within the pixel area, the relative position of the light-shielding structure and the sub-pixel, the number of light-shielding structures, or the shape of the light-shielding structure.

[0089] In one embodiment, Figure 15 This is a partial top view schematic diagram of another optional embodiment of the first display area of ​​the display panel provided in the embodiments of this application. (See attached diagram.) Figure 15 As shown, pixel region P20 includes a light-shielding structure Z1, and pixel region P21 includes a light-shielding structure Z2. The areas of light-shielding structures Z1 and Z2 are different. When the light-shielding structure overlaps with the non-light-emitting area, the size of the light-shielding structure affects the overlap area, thus affecting the shape of the light-transmitting area within the non-light-emitting area, and consequently affecting the shape of the diffraction grating formed by the pixel region corresponding to that non-light-emitting area. In this embodiment, the different sizes of the light-shielding structures in adjacent pixel regions result in different shapes of the diffraction gratings formed by the adjacent pixel regions. This breaks the pattern of short-period diffraction gratings with a period of one pixel region, improving the diffraction phenomenon caused by light penetrating the display panel.

[0090] In one embodiment, Figure 16 This is a partial top view schematic diagram of another optional embodiment of the first display area of ​​the display panel provided in the embodiments of this application. (See attached diagram.) Figure 16 As shown, pixel region P22 includes a light-shielding structure Z3, and pixel region P23 includes a light-shielding structure Z4. The relative positions of light-shielding structures Z3 and Z4 with the light-emitting areas of the sub-pixels are different, and adjacent pixel regions P22 and P23 have different structures. The light-shielding structures overlap with the non-light-emitting areas. The relative positions of the light-shielding structures with the light-emitting areas of the sub-pixels affect the overlap position of the light-shielding structures with the non-light-emitting areas, thereby affecting the shape of the light-transmitting area within the non-light-emitting area, and consequently affecting the shape of the diffraction grating formed by the pixel region corresponding to that non-light-emitting area. In this embodiment, the relative positions of the light-shielding structures with the light-emitting areas of the sub-pixels in two adjacent pixel regions are different, resulting in different shapes of the diffraction gratings formed by the two adjacent pixel regions. This can break the pattern of short-period diffraction gratings with a period of one pixel region, improving the diffraction phenomenon caused by light penetrating the display panel.

[0091] In one embodiment, two adjacent pixel regions with different structures both include light-shielding structures, and the number of light-shielding structures in the two pixel regions is different. This application does not limit the number of light-shielding structures in a pixel region. Different numbers of light-shielding structures result in different total overlap positions between the light-shielding structures and the non-emitting areas, leading to different shapes of the light-transmitting areas within the non-emitting areas of the two adjacent pixel regions, and consequently, different shapes of the diffraction gratings formed by the two adjacent pixel regions. This can break the pattern of short-period diffraction gratings with a period of one pixel.

[0092] In one embodiment, two adjacent pixel regions with different structures both include a light-shielding structure, and the shapes of the light-shielding structures in the two pixel regions are different. This application does not limit the specific shape of the light-shielding structure in the pixel region. If the light-shielding structure overlaps with the non-emitting area, the shape of the light-shielding structure can affect the shape of the light-transmitting area within the non-emitting area. If the shapes of the light-shielding structures in the two pixel regions are different, the shapes of the diffraction gratings formed by the two adjacent pixel regions will be different, which can break the regularity of short-period diffraction gratings with a period of one pixel region.

[0093] In the display panel provided in this application embodiment, the position of the light-shielding structure in the film layer of the display panel includes various cases. The light-shielding structure can be located in the same layer as the existing film layer structure in the display panel, or a film layer structure can be added to the display panel to create the light-shielding structure. The following embodiments will illustrate the film layer position of the light-shielding structure.

[0094] In one embodiment, Figure 17 for Figure 13 A schematic diagram of an alternative membrane structure at the location of the tangent line AA'. (See diagram below.) Figure 17 As shown, the display panel includes a substrate 101, an array layer 102, and a display layer 103. The structure of some film layers in the panel can also be referenced above. Figure 5 The corresponding embodiments are explained below. In the embodiments of this application, the sub-pixel sp includes a first electrode a1, a light-emitting layer b1, and a second electrode c1 stacked sequentially; that is, one sub-pixel sp corresponds to one organic light-emitting area device. Optionally, the first electrode a1 is an anode and the second electrode c1 is a cathode. The light-shielding structure Z is fabricated on the same layer and with the same material as the first electrode a1. During the manufacturing of the display panel, a whole layer of film material for fabricating the first electrode is first laid, and then the film layer is etched by a material etching process, simultaneously forming the pattern of the light-shielding structure and the pattern of the first electrode. The light-shielding structure reuses the process of the first electrode to complete the fabrication, requiring only the design of the shape of the mask used in the fabrication of the first electrode, without the need to add an additional film layer structure, thus simplifying the process.

[0095] Figure 17In the schematic embodiment, the light shielding structure Z is not connected with the first electrode a1. In another embodiment, the light shielding structure is made of the same material as the first electrode in the same layer, and part of the light shielding structure is connected with the first electrode. In this embodiment, only the shape of the mask plate used for etching the first electrode needs to be designed, and the display panel can be manufactured.

[0096] In an embodiment, Figure 18 To Figure 13 Another optional embodiment of the film layer structure at the tangent position A-A' is shown in the schematic diagram. As shown, the light shielding structure Z is located on the side of the substrate 101 away from the array layer 102. In this embodiment, the light shielding structure Z can be attached to the back of the substrate 101. The arrangement of the light shielding structure Z does not require changes to the manufacturing process of the array layer 102 and the display layer 103. Figure 18

[0097] In an embodiment, the light shielding structure can also be located between the substrate and the array layer, that is, the light shielding structure is first manufactured on the substrate during the manufacturing of the display panel, and the process of the array layer is started after the manufacturing process of the light shielding structure is completed.

[0098] In some optional embodiments, the light shielding structure includes a light shielding layer, and the light shielding structure can be made of existing materials that can absorb or reflect light. The manufacturing materials of the light shielding structure include at least one or more of metal, metal oxide, and organic polymer.

[0099] Further, in some optional embodiments, the display panel provided by the embodiments of the present application includes at least two repeating units arranged in an array in the first display area, and each repeating unit includes at least two pixel areas. In one repeating unit, at least part of the structures of two adjacent pixel areas are different. The embodiments of the present application do not limit the number of pixel areas in the repeating unit. One repeating unit can include two pixel areas, three pixel areas, or more pixel areas. In one repeating unit, all pixel areas can be arranged in sequence along a certain direction, or all pixel areas can be arranged in an array. In one repeating unit, part of the structures of two adjacent pixel areas can be different, and part of the structures of two adjacent pixel areas can be the same. Any two adjacent pixel areas can have different structures.

[0100] ​Compared with the related art, the period length of the diffraction grating is increased, the short-range non-periodic and long-range periodic pixel region arrangement is realized, the diffraction phenomenon caused by light penetrating the display panel is weakened, and thus the optical effect of the under-screen optical element is improved. In addition, in the evaporation process of the light-emitting layer in the display panel, the mask plate used in the evaporation process is very thin, and the pixel definition layer plays a certain supporting role on the mask plate. According to the embodiment of the present application, the openings of the pixel definition layer are arranged in an array with a period of one repeating unit, so that the mask plate is uniformly stressed in the evaporation process, thereby ensuring the flatness requirement of the mask plate and the reliability of the evaporation process.

[0101] In an embodiment, the repeating unit includes two pixel regions. Figure 19 Another optional embodiment of the first display region in the display panel provided by the embodiment of the present application is a partial top view schematic diagram. As shown in Figure 19 The repeating unit CC includes two pixel regions, namely pixel region P24 and pixel region P25, and the structures of the pixel region P24 and the pixel region P25 are different. The plurality of repeating units CC are arranged in sequence in the first direction x and arranged in sequence in the second direction y, that is, the plurality of repeating units CC are arranged in an array in the first display region.

[0102] In an embodiment, the repeating unit includes three pixel regions. Figure 20 Another optional embodiment of the first display region in the display panel provided by the embodiment of the present application is a partial top view schematic diagram. As shown in Figure 20 The repeating unit CC includes three pixel regions, namely pixel region P26, pixel region P27 and pixel region P28. The structures of the adjacent pixel region P26 and the pixel region P27 are different, and the structures of the adjacent pixel region P27 and the pixel region P28 are also different. The plurality of repeating units CC are arranged in sequence in the first direction x and arranged in sequence in the second direction y, that is, the plurality of repeating units CC are arranged in an array in the first display region.

[0103] Figure 20 In the embodiment, the repeating unit is understood as the "ABC" structure, that is, the structures of any two adjacent pixel regions in the repeating unit are different. When the repeating unit includes three pixel regions, in some optional embodiments, the repeating unit can also be "ABB" structure, or can also be "AAB" structure, that is, in the repeating unit, the structures of part of the adjacent two pixel regions are different, and the structures of the remaining part of the adjacent two pixel regions are the same, which is not shown in the figure.

[0104] In one embodiment, the repeating unit includes four pixel regions. Figure 21 This is a partial top view schematic diagram of another optional embodiment of the first display area in the display panel provided in the embodiments of this application. (See attached diagram.) Figure 21 As shown, the repeating unit CC includes four pixel areas, namely pixel area P29, pixel area P30, pixel area P31 and pixel area P32. The structures of any two adjacent pixel areas in the repeating unit CC are different. Multiple repeating units CC are arranged sequentially in the first direction x and in the second direction y, that is, multiple repeating units CC are arrayed in the first display area.

[0105] Figure 21 The embodiments illustrate a case where the structures of any two adjacent pixel regions in a repeating unit are different. When the repeating unit includes four pixel regions, in some optional embodiments, the structures of some adjacent pixel regions may be different, while the structures of the remaining adjacent pixel regions may be the same.

[0106] In some optional implementations, at least two pixel regions within the repeating unit are arranged in an array, and at least some pixel regions have the same structure as their adjacent pixel regions in the diagonal direction. Optionally, all pixel regions within the repeating unit are arranged in an "n*m" array, where n≥2, m≥2, and n and m are both integers. In this embodiment, by setting repeating units within the first display area, the period of the diffraction grating in the first display area is made to be the length of one repeating unit, increasing the period length of the diffraction grating and achieving a short-range non-periodic and long-range periodic pixel region structure. This can weaken the diffraction phenomenon caused by light penetrating the display panel, thereby improving the optical effect of the under-screen optical elements. In addition, if at least some pixel regions within the repeating unit have the same structure as their adjacent pixel regions in the diagonal direction, then some adjacent pixel regions within the repeating unit have different structures, while the remaining adjacent pixel regions have the same structure. Taking a repeating unit comprising four arrayed pixel regions as an example, two adjacent pixel regions in the diagonal direction can be set to have the same structure. In the design, at least two different pixel region structures can be designed to form a repeating unit. This implementation method can reduce the number of pixel area structure designs while improving diffraction phenomena, which helps to reduce the design difficulty of the mask used in the manufacturing process.

[0107] In one embodiment, the repeating unit includes four pixel regions as an example. Figure 22 This is a partial top view schematic diagram of another optional embodiment of the first display area in the display panel provided in the embodiments of this application. (See attached diagram.) Figure 22As shown in the figure, the repeating unit CC includes four pixel regions arranged in an array, which are pixel region P33, pixel region P34, pixel region P35 and pixel region P36 respectively. Among them, the structure of pixel region P33 is the same as that of pixel region P36 adjacent to it in the diagonal direction, and the structure of pixel region P34 is the same as that of pixel region P35 adjacent to it in the diagonal direction.

[0108] In an embodiment, taking the case that a repeating unit includes six pixel regions as an example. Figure 23 Another optional embodiment of the first display area in the display panel provided by the present application is shown in the partial top view. As shown in the figure, Figure 23 As shown in the figure, the repeating unit CC includes six pixel regions arranged in a "2*3" array, which are pixel region P37, pixel region P38, pixel region P39, pixel region P40, pixel region P41 and pixel region P42 respectively. Among them, the structure of pixel region P40 is the same as that of pixel region P38 adjacent to it in the diagonal direction, and the structure of pixel region P41 is the same as that of pixel region P39 adjacent to it in the diagonal direction. This embodiment illustrates the case that in one repeating unit, the structures of some adjacent two pixel regions are different, and the structures of the remaining adjacent two pixel regions are the same.

[0109] In some optional embodiments, in the first display area, the structures of any two adjacent pixel regions are different. In an embodiment, the arrangement of the repeating unit CC in the first display area can be referred to the illustration in the above Figure 21 In this embodiment, the arrangement mode of the pixel regions in the first display area still has certain regularity, forming a long-period diffraction grating with one repeating unit as a period. In another embodiment, in the first display area, the structures of any two adjacent pixel regions are different, and the arrangement mode of the pixel regions has no regularity, then a non-period diffraction grating can be formed. In this embodiment, the first display area can include pixel regions with the same structure, but these pixel regions with the same structure are not adjacent.

[0110] It should be noted that the above Figure 19 to Figure 23 are only for illustrating the various arrangement modes of the pixel regions in the repeating unit in the embodiments of the present application, Figure 19 to Figure 23 the shape of the sub-pixel in one pixel region and the arrangement mode of the sub-pixels in the pixel region are not limitations on the present application.

[0111] In some optional implementations, the display panel provided in this application embodiment achieves different structures between adjacent pixel areas by changing the arrangement of signal lines within the pixel area in the first display area. The pixel area includes a light-emitting area and a non-light-emitting area, with one sub-pixel corresponding to one light-emitting area, and the non-light-emitting area surrounding the light-emitting area. The display area also includes at least two signal lines, each including a first signal line segment located in the non-light-emitting area. Within the first display area, in two adjacent pixel areas with different structures, at least one of the following differs: the line width of the first signal line segment; the line shape of the first signal line segment; and the spacing between two adjacent first signal line segments. The line width is the width of the first signal line segment perpendicular to its extension direction; different line widths result in changes in the area occupied by the first signal line segment in the non-light-emitting area. The line shape of the first signal line segment refers to its shape, such as a straight line, curve, wavy line, or broken line.

[0112] The signal lines described in this application embodiment include signal lines used to drive the display panel for display, and signal lines supporting other functions of the display panel (such as touch function). Multiple signal lines include data lines, scan lines, power signal lines, reset signal lines, touch signal lines, and signal traces in the pixel driving circuit. In the display panel, some signal lines overlap with the light-emitting area, while others overlap with the non-light-emitting area. In display panels using under-display optical element solutions, the signal lines overlapping with the non-light-emitting area also form a diffraction grating, causing diffraction of light penetrating the display panel. In this application embodiment, by adjusting the arrangement structure of the signal lines overlapping in the non-light-emitting area (i.e., the first signal line segment located in the non-light-emitting area), the structures of two adjacent pixel areas are different, thus resulting in different shapes of the diffraction gratings formed by the two adjacent pixel areas.

[0113] Specifically, in one embodiment, the spacing between two adjacent first signal line segments within two adjacent pixel areas is different. Figure 24 This is a partial top view schematic diagram of another optional embodiment of the first display area in the display panel provided in the embodiments of this application. (See attached diagram.) Figure 24 The illustration shows a pixel region comprising three luminescent regions G and a non-luminescent region FG surrounding the luminescent regions G. Each pixel region includes a first signal line segment D1 located within the non-luminescent region FG. The spacing between two adjacent first signal line segments D1 within the non-luminescent region FG in pixel regions P45 and P46 is different. Consequently, the shapes of the light-transmitting areas of adjacent pixel regions P45 and P46 are different. This embodiment can achieve different light-transmitting areas between two adjacent pixel regions by adjusting the arrangement of the first signal line segments within the pixel region, thereby forming different diffraction gratings between adjacent pixel regions and disrupting the regularity of a periodic diffraction grating with a period equal to the length of a pixel region.

[0114] Further, in some optional embodiments, the arrangement structure of the first signal line segment in the non-light-emitting area in the pixel is adjusted to realize the structural difference between the two adjacent pixel areas. The arrangement of the pixel areas with short-range non-periodic and long-range periodic structures can improve the diffraction phenomenon when light penetrates the display panel, thereby improving the optical effect of the optical element under the screen. Meanwhile, the periodic arrangement of the pixel areas can ensure uniform stress on the mask plate during the evaporation process, thereby meeting the flatness requirement of the mask plate and ensuring the reliability of the evaporation process.

[0115] It should be noted that, in the case of no mutual conflict, the scheme of adjusting the structure in the pixel area by setting the light-shielding structure, the scheme of adjusting the arrangement mode of the light-emitting area of the sub-pixel in the pixel area, and the scheme of adjusting the arrangement structure of the first signal line segment in the pixel area can be combined with each other to realize the structural difference between the two adjacent pixel areas.

[0116] Based on the same inventive concept, the present application also provides an electronic device, Figure 25 The electronic device provided in the embodiments of the present application is shown in FIG. 10. Figure 25 As shown in FIG. 10, the electronic device includes the display panel 100 provided in any of the embodiments of the present application, and the electronic device further includes an optical element (not shown) located below the first display area AA1.
