[0002] With the development of consumer electronic products such as mobile phones, including display panels and cameras, people's requirements for these products are no longer limited to functionality, but have also shifted towards design, artistry, and good visual experience. For example, full-screen phones with a high screen-to-body ratio are becoming increasingly popular.

[0003] Taking mobile phones as an example, since cameras, light sensors and other components need to be placed on the front of the phone, the existing solution is generally to design a non-display area at the top of the screen, such as the now widely used "notch screen" and "water drop screen" solutions. These solutions are difficult to achieve a true full-screen display effect. Summary of the Invention

[0004] The present invention provides a display panel and a display device, so as to increase the screen-to-body ratio of the display panel and simultaneously improve the imaging quality of a camera outside the display panel.

[0035] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be fully described below in conjunction with the accompanying drawings of the embodiments of the present invention through specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] Figure 1 This is a schematic diagram of the structure of a display panel in the prior art. Figure 1 As shown, the display panel of the prior art includes a non-display area AB' and a display area AA' surrounding the non-display area AB', wherein the non-display area AB' is a sensor reserved area where a sensor can be set. Figure 1 It can be seen that it is difficult to achieve a true full-screen display effect due to the existence of the non-display area AB′.

[0037] Based on the above problems, the embodiment of the present application provides a display panel, which comprises a first display area and a second display area, and the second display area surrounds the first display area; the display panel further comprises a first substrate, and the first substrate comprises a first substrate substrate; the first display area comprises a plurality of light emitting units on the first substrate substrate, and the light emitting unit comprises a driving circuit and an organic light emitting element, and the driving circuit is used for driving the organic light emitting element to emit light; the first display area further comprises a plurality of first light transmission holes, and in the direction perpendicular to the plane where the first substrate substrate is located, the first light transmission hole does not overlap with the light emitting unit, and the first light transmission hole is non-rectangular; the first display area comprises a first sub-display area and a second sub-display area, and in the first sub-display area, the sum of the areas of the first light transmission holes in a unit area is S1; in the second sub-display area, the sum of the areas of the first light transmission holes in a unit area is S2, wherein S1>S2. By adopting the above technical scheme, the plurality of first light transmission holes are arranged in the first display area, the external light enters the camera on the backlight side of the display panel through the plurality of first light transmission holes, the camera receives sufficient light to meet the camera function, and the plurality of light emitting units are arranged in the first display area, the normal display of the first display area is realized through the plurality of light emitting units when the display panel needs to display, the screen ratio of the display panel is improved, and the full-screen display is realized. In addition, since the first light transmission hole is non-rectangular, the diffraction of the light passing through the first light transmission hole can be effectively reduced, and the imaging quality of the camera corresponding to the first display area AA on the backlight side of the display panel is improved. Further, since the sum of the areas of the first light transmission holes in a unit area S1 in the first sub-display area is greater than the sum of the areas of the first light transmission holes in a unit area S2 in the second sub-display area, that is, the first light transmission holes are arranged irregularly in the first display area, the diffraction is further avoided, and the imaging quality is improved.

[0038] The above is the core idea of the present application, and the technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0039] Figure 2 is a structural schematic diagram of a display panel provided by the embodiment of the present application, Figure 3 is a local structural schematic diagram of a first display area provided by the embodiment of the present application, Figure 4 is Figure 3 is a cross-sectional structural schematic diagram along the direction of QQ' in the above-mentioned Figure 2 , Figure 3 and Figure 4As shown, the display panel provided by the embodiment includes a first display area AB and a second display area AA, the second display area AA surrounds the first display area AB; the display panel further includes a first substrate 100, the first substrate 100 includes a first substrate 30; the first display area AB includes a plurality of light emitting units 10 on the first substrate 30, the light emitting unit 10 includes a driving circuit 11 and an organic light emitting element 12, the driving circuit 11 is used for driving the organic light emitting element 12 to emit light; the first display area AB further includes a plurality of first light transmission holes 20, in the direction perpendicular to the plane where the first substrate 30 is located, the first light transmission hole 20 does not overlap with the light emitting unit 10, and the first light transmission hole 20 is non-rectangular; the first display area AB includes a first sub-display area BB and a second sub-display area BC, in the first sub-display area BB, the sum of the areas of the first light transmission hole 20 in the unit area is S1; in the second sub-display area BC, the sum of the areas of the first light transmission hole 20 in the unit area is S2, wherein S1>S2.

[0040] It can be understood that the display panel provided by the embodiment of the application is suitable for a display device which needs to set a sensor under the screen, wherein the sensor may, for example, be a camera. Since the shape of the area corresponding to the camera is generally set to be circular, the first display area AB is set to be a circular area in the examples in the Figure 2 and Figure 3 The first display area AB is a circular area in the examples in the and, but this does not constitute a limitation on the present application, and the first display area AB may also be a polygonal area or an elliptical area, etc. In addition, the embodiment does not specifically limit the position of the first display area AB in the display panel, Figure 2 only taking the case that the first display area AB is located at the upper left corner of the display panel as an example to illustrate that, in other optional embodiments, the first display area AB may also be located at the center area of the display panel, etc. The light emitting unit 10 includes a driving circuit 11 and an organic light emitting element 12, wherein the driving circuit 11 is used for driving the organic light emitting element 12 to emit light, so as to display a to-be-displayed picture. The first display area AB includes a plurality of first light transmission holes 20, and the areas of all the first light transmission holes 20 are equal to each other.

[0041] Specifically, in the embodiment of the present invention, not only does the second display area AA include multiple light-emitting units (not shown in the figure) located on the first base substrate 30 to enable the second display area AA to display; the first display area AB also includes multiple light-emitting units 10 located on the first base substrate 30. That is, when the display panel displays, it can display not only through the second display area AA, but also through the first display area AB, thereby achieving full-screen display of the display panel. At the same time, the first display area AB also includes multiple first light-transmitting holes 20. In the direction perpendicular to the plane of the first base substrate 30, the first light-transmitting holes 20 do not overlap with the light-emitting units 10. External light can enter the camera on the backlight side of the display panel through the multiple first light-transmitting holes 20, ensuring that the camera receives sufficient light to meet the camera's camera function. That is, the first display area AB can not only meet the camera's camera function, but also achieve normal display. That is, this technical solution improves the screen-to-body ratio of the display panel while ensuring the camera's camera function, achieving a full-screen display effect.

[0042] Furthermore, because when the light-transmitting areas are rectangular and regularly arranged, external light is easily diffracted when passing through the light-transmitting areas, the embodiment of the present invention sets the shape of the multiple first light-transmitting holes 20 to be non-rectangular, and in the first sub-display area BB, the sum of the areas of the first light-transmitting holes 20 per unit area is S1; in the second sub-display area BC, the sum of the areas of the first light-transmitting holes 20 per unit area is S2, wherein S1>S2, that is, the first light-transmitting holes 20 are non-rectangular and irregularly arranged. In this way, diffraction of external light when passing through the multiple first light-transmitting holes 20 can be avoided, thereby improving the imaging quality of the camera on the backlight side of the display panel opposite to the first display area AA.

[0043] In summary, the embodiment of the present invention sets a plurality of first light-transmitting holes in the first display area, and external light enters the camera on the backlight side of the display panel through the plurality of first light-transmitting holes, thereby ensuring that the camera receives sufficient light to meet the camera's camera function; at the same time, by setting a plurality of light-emitting units in the first display area, when the display panel is required to display, the normal display of the first display area can be achieved through the plurality of light-emitting units, thereby improving the screen-to-body ratio of the display panel and achieving full-screen display; in addition, since the first light-transmitting holes are non-rectangular, the diffraction of light passing through the first light-transmitting holes can be effectively reduced, thereby improving the imaging quality of the camera located on the backlight side of the display panel and corresponding to the first display area AA; further, since the sum S1 of the areas of the first light-transmitting holes per unit area in the first sub-display area is greater than the sum S2 of the areas of the first light-transmitting holes per unit area in the second sub-display area, that is, the first light-transmitting holes are irregularly arranged in the first display area, further avoiding the occurrence of diffraction and improving the imaging quality.

[0044] Optionally, the shape of the first light-transmitting hole 20 includes at least one of a circle, an ellipse, and a rounded polygon. Figure 2 and Figure 3 The first light-transmitting hole 20 is exemplarily described as a circle. In other optional embodiments, the shape of the first light-transmitting hole 20 may include only one of an ellipse or a rounded polygon, or a combination of multiple shapes. Figure 5 is a partial structural diagram of another first display area provided by an embodiment of the present invention, such as Figure 5 As shown, the shape of the first light-transmitting hole 20 includes a combination of a rounded quadrilateral and a circle.

[0045] It should be noted that the shape of the first light-transmitting hole 20 includes but is not limited to the above examples. Those skilled in the art can set the shape of the first light-transmitting hole 20 according to product requirements. No specific limitation is made in the present invention, as long as diffraction of light when passing through the first light-transmitting hole 20 can be avoided.

[0046] It can be understood that, although the shapes of the first light transmission holes 20 may be different, the areas of the plurality of first light transmission holes 20 are equal to each other.

[0047] It is understandable that, since there are many ways to form the first light-transmitting hole 20, in order to clearly show the difference between the first light-transmitting hole 20 and the light-emitting unit 10 and other areas, Figure 3 and Figure 5 The area except the light emitting unit 10 and the first light-transmitting hole 20 is filled with a filling pattern different from that of the light emitting unit 10 and the first light-transmitting hole 20. The same is true for the following embodiments, which will not be described in detail. How the first light-transmitting hole 20 is formed will be described in detail in the following embodiments.

[0048] Optionally, there are multiple implementations for forming the first light-transmitting hole 20 , which will be described in detail below with reference to specific examples.

[0049] Optional, Figure 6 is a partial structural diagram of another first display area provided by an embodiment of the present invention. Figure 7 yes Figure 6 Schematic diagram of the cross-sectional structure along the WW' direction, as shown in Figure 6 and Figure 7 As shown, the display panel also includes a light-shielding layer 40 located in the first display area AB and on the first base substrate 30; the light-shielding layer 40 includes a plurality of first openings 41 and a plurality of second openings 42; in a direction perpendicular to the plane of the first base substrate 30, the organic light-emitting element 12 at least partially overlaps with the first opening 41; the second opening 42 is a first light-transmitting hole 20.

[0050] The display panel further includes metal traces (not shown) located on the first base substrate 30. The metal traces may include, for example, data lines and scan lines. Gaps exist between the metal traces, and when external light passes through these traces, diffraction may occur. Consequently, external light entering the display panel and being received by a camera on the backlight side of the display panel may affect image quality. Therefore, in this embodiment, a light shielding layer 40 is provided on the first base substrate 30 to shield the metal traces, effectively preventing diffraction of external light by the gaps between the metal traces. The light shielding layer 40 also includes a plurality of first openings 41 and a plurality of second openings 42. The organic light emitting element 12 at least partially overlaps with the first openings 41 in a direction perpendicular to the plane of the first base substrate 30, allowing light emitted by the organic light emitting element 12 to pass through the first openings 41, thereby achieving normal display of the first display area AB. The second openings 42 are first light-transmitting holes 20, allowing external light to pass through the second openings 42 and be received by a camera or other light-sensing element on the backlight side of the display panel, thereby fulfilling their corresponding functions. In this way, the display of the first display area AB is not affected and diffraction can be avoided.

[0051] Optionally, the material of the light shielding layer 40 includes black photoresist or black metal.

[0052] It should be noted that the material of the light shielding layer 40 includes but is not limited to the above examples. Those skilled in the art can select the material of the light shielding layer 40 according to actual conditions, and this embodiment does not specifically limit the material.

[0053] It should be noted that the specific film position of the light shielding layer 40 is not specifically limited in this embodiment, as long as the light shielding layer 40 can effectively prevent the gaps between the metal traces from diffracting external light, Figure 7 The light-shielding layer 40 is only located on the side of the organic light-emitting element 12 away from the first base substrate 30, that is, the light-shielding layer 40 is set separately as an example for explanation, but the light-shielding layer 40 can also be set in the same layer as the film layer in the display panel, which can avoid diffraction and reduce the process steps. The following is an example of the light-shielding layer 40 being set in the same layer as the film layer in the display panel.

[0054] Optional, Figure 8 : is a schematic diagram of a partial film layer structure of a first display area provided by an embodiment of the present invention, such as Figure 8 As shown, the organic light-emitting element 12 includes an anode 121 located on the side of the driving circuit 11 away from the first base substrate 30, a light-emitting layer 122 located on the side of the anode 121 away from the driving circuit 11, and a cathode 123 located on the side of the light-emitting layer 122 away from the anode 121; the anode 121 and the light-shielding layer 40 are made of the same material and are arranged on the same layer.

[0055] In this embodiment, the anode 121 of the organic light-emitting element 12 can be formed using indium tin oxide, silver, and indium tin oxide (ITO+Ag+ITO). When forming the anode layer, Ag can be retained as the light-shielding layer 40. By forming the anode 121 and the light-shielding layer 40 using the same material and in the same process, that is, forming the light-shielding layer 40 simultaneously with the anode 121, no additional process step is required, thus reducing the process flow and lowering the production cost of the display panel. Furthermore, compared to when the anode 121 and the light-shielding layer 40 are provided in different film layers, the co-layer arrangement of the anode 121 and the light-shielding layer 40 in this embodiment can reduce the overall thickness of the display panel.

[0056] Optional, Figure 9 This is another schematic diagram of a partial film structure of the first display area provided by an embodiment of the present invention, such as Figure 9 As shown, the driving circuit 11 includes a thin film transistor 112 and a storage capacitor 113; the storage capacitor 113 includes a first electrode 1131 and a second electrode 1132; the thin film transistor 112 includes a gate 1121, a source 1122 and a drain 1123; the organic light emitting element 12 includes an anode 121, a light emitting layer 122 and a cathode 123; the display panel includes a barrier layer M0 located on a first base substrate 30, an active layer PL located on a side of the barrier layer M0 away from the first base substrate 30, a first metal layer M1 located on a side of the active layer PL away from the first base substrate 30, a second metal layer M2 located on a side of the first metal layer M1 away from the first base substrate 30, a third metal layer M3 located on a side of the second metal layer M2 away from the first base substrate 30, and a cathode 123 located on the third metal layer M1. The metal layer M3 includes an anode layer RE on a side away from the first base substrate 30, a light-emitting layer EML on a side of the anode layer RE away from the first base substrate 30, and a cathode layer CA on a side of the light-emitting layer EML away from the first base substrate 30; the blocking layer M0 includes a light-shielding portion 50, and the light-shielding portion 50 is located on a side of the gate electrode 1121 of the thin film transistor 112 close to the first base substrate 30; further, the light-shielding portion 50 is located on a side of the active layer PL close to the first base substrate 30; the first metal layer M1 includes the gate electrode 1121 of the thin film transistor 112 and the first electrode plate 1131 of the storage capacitor 113; the second metal layer M2 includes the second electrode plate 1132 of the storage capacitor 113; and the third metal layer M3 includes the source electrode 1122 and the drain electrode 1123 of the thin film transistor 112.

[0057] Among them, considering that some impurity ions precipitated from the first base substrate 30 may enter the channel of the thin film transistor 112 and thus affect the performance of the thin film transistor 112, this embodiment sets a shading portion 50 between the first base substrate 30 and the thin film transistor 112, and blocks the thin film transistor 112 by the shading portion 50, thereby preventing some impurity ions precipitated from the first base substrate 30 from entering the channel of the thin film transistor 112, thereby avoiding the influence of the impurity ions on the performance of the thin film transistor 112.

[0058] Optionally, the display panel further includes a power signal line (not shown in the figure), wherein the power signal line includes a first power signal line extending in the column direction and a second power signal line extending in the row direction, and the first power signal line is laterally connected by the second power signal line, thereby reducing the voltage drop of the power signal. In addition to including the second electrode 1132 of the storage capacitor 113, the second metal layer M2 also includes the second power signal, and the third metal layer M3 includes the first power signal line in addition to the source 1122 and the drain 1123 of the thin film transistor 112. This technical solution reduces the voltage drop of the power signal while reducing the process flow by respectively arranging the first power signal line and the second power signal line of the power signal line in the third metal layer M3 and the second metal layer M2.

[0059] Optional, see Figure 9 , the blocking layer M0 further includes a light shielding layer 40 .

[0060] In this embodiment, by forming the light shielding layer 40 and the light shielding portion 50 using the same material and in the same process, that is, forming the light shielding layer 40 simultaneously with the light shielding portion 50, no additional process step is required, thus streamlining the process flow and reducing the manufacturing cost of the display panel. Furthermore, compared to when the light shielding layer 40 and the light shielding portion 50 are provided in different film layers, the provision of the light shielding layer 40 and the light shielding portion 50 in the same layer in this embodiment can reduce the overall thickness of the display panel.

[0061] Optional, Figure 10 : is a schematic diagram of a partial film layer structure of a first display area provided by an embodiment of the present invention, such as Figure 10 As shown, the fourth metal layer M4 is further included, which is located on a side of the third metal layer M3 away from the first substrate 30 ; the fourth metal layer M4 includes a light shielding layer 40 .

[0062] In this embodiment, the display panel further includes a fourth metal layer M4 located on a side of the third metal layer M3 away from the first base substrate 30, and the fourth metal layer M4 includes a light shielding layer 40. The light shielding layer 40 shields the metal traces between adjacent light-emitting elements 10, effectively preventing diffraction of external light by the gaps between the metal traces. This improves the imaging quality of the camera outside the display panel.

[0063] Optionally, the display panel further includes data lines (not shown), wherein the data lines include a first data line and a second data line extending in the column direction. The third metal layer M3 includes the source electrode 1122 and the drain electrode 1123 of the thin-film transistor 112 as well as the first data line, and the fourth metal layer M4 includes the second data line as well as the light-shielding layer 40. The first data line and the second data line are connected via a perforation. This technical solution reduces the voltage drop across the data lines while simplifying the process flow by disposing the first data line and the second data line in the third metal layer M3 and the fourth metal layer M4, respectively.

[0064] Through the analysis of the above embodiments, it can be seen that the light-shielding layer 40 not only blocks the metal traces between adjacent light-emitting elements 10, but also effectively prevents the gaps between the metal traces from diffracting external light. At the same time, the light-shielding layer 40 includes multiple first openings 41 and multiple second openings 42. In a direction perpendicular to the plane of the first base substrate 30, the organic light-emitting element 10 and the first openings 41 at least partially overlap, allowing light emitted by the organic light-emitting element 10 to pass through the first openings 41, thereby achieving normal display of the first display area AB. The second openings 42 are first light-transmitting holes 20, allowing external light to pass through the second openings 42 and be received by the camera or other light-sensing element on the backlight side of the display panel to meet its corresponding functions. In this way, while not affecting the display of the first display area AB, diffraction can also be avoided. Furthermore, by providing the light-shielding layer 40 and the film structure within the display panel, such as the anode 121 or the shielding portion 50, on the same layer, no additional process is required, which reduces the process flow and reduces the production cost of the display panel.

[0065] Optional, Figure 11 is a partial structural diagram of a first display area provided by an embodiment of the present invention, such as Figure 11 As shown, in a direction perpendicular to the plane where the first base substrate 30 is located, the first light-transmitting hole 20 is an area surrounded by adjacent light-emitting units 10 and the connection lines between adjacent light-emitting units 10 .

The present embodiment forms a non-rectangular first light transmission hole 20 around the four adjacent light emitting elements 10 and the scan line S, the data line D1 and the power signal line P1 between the four adjacent light emitting elements 10 in the direction perpendicular to the plane where the first substrate 30 is located, so that external light passes through the first light transmission hole 20 and is received by the camera or other light sensing element outside the display panel to meet its corresponding function. Because the first light transmission hole 20 is in a non-rectangular arrangement, so as to avoid diffraction of external light when it passes through the light transmission area TT, and to improve the imaging quality of the camera opposite the first display area AA.

[0069] In this embodiment, the first light-transmitting holes 20 penetrate the first insulating layer 60, the second insulating layer 61, the third insulating layer 62, the planarization layer PLN and the pixel definition layer PDL, so that when external light passes through multiple first light-transmitting holes 20 and enters the camera on the backlight side of the display panel, the number and thickness of the film layers passed through are reduced, thereby reducing light loss and improving transmittance, thereby improving the imaging quality of the camera located on the backlight side of the display panel and corresponding to the first display area AA.

For example, Figure 13 This is another schematic diagram of a partial film structure of the first display area provided by an embodiment of the present invention, such as Figure 13As shown, the first light-transmissive hole 20 can also penetrate the planarization layer PLN and the pixel definition layer PDL.

Figure 15 As shown, the first display area AB further includes: a plurality of second light-transmissive holes 21; in the direction perpendicular to the plane where the first substrate 30 is located, the second light-transmissive hole 21 does not overlap with the light-emitting unit 10, and the second light-transmissive hole 21 is non-rectangular; the area of the first light-transmissive hole 20 is a first area S11; the area of the second light-transmissive hole 21 is a second area S12; wherein S11>S12; in the first sub-display area BB, the sum of the areas of the second light-transmissive hole 21 per unit area is S3; in the second sub-display area BC, the sum of the areas of the second light-transmissive hole 21 per unit area is S4, S3

[0073] In this embodiment, the first display area AB further includes a plurality of second light-transmissive holes 21, and the areas of all the second light-transmissive holes 21 are equal to each other. External light enters the camera arranged on the back light side of the display panel through the plurality of first light-transmissive holes 20 and the plurality of second light-transmissive holes 21, ensuring that the camera receives sufficient light to meet the camera function; in addition, since the second light-transmissive hole 21 is non-rectangular, and in the first sub-display area BB, the sum of the areas of the second light-transmissive hole 21 per unit area S3 is less than the sum of the areas of the second light-transmissive hole 21 per unit area S4 in the second sub-display area BC, that is, the second light-transmissive hole 21 is arranged irregularly, so that the diffraction of external light through the plurality of second light-transmissive holes 21 can be avoided, and the imaging quality of the camera on the back light side of the display panel opposite to the first display area AA can be improved.

It can be understood that although the shape of the second light-transmissive hole 21 can be different, the areas of the plurality of second light-transmissive holes 21 are equal to each other.

That is, the technical solution makes the areas of the first sub-display area BB and the second sub-display area BC regular on the basis that the first light transmission hole 20 and the second light transmission hole 21 are non-rectangular and irregularly arranged, effectively avoiding diffraction of light when passing through the first light transmission hole 20 and the second light transmission hole 21, and at the same time improving the uniformity of the transmittance of the first display area AB, further improving the imaging quality of the camera on the backlight side of the display panel.

Figure 18 yes Figure 17 The structural diagram of the two first light-transmitting hole groups in FIG. Figure 17 and Figure 18 As shown, the display panel includes multiple first light-transmitting hole groups 70; each first light-transmitting hole group 70 is arranged in a ring; multiple first light-transmitting hole groups 70 are arranged in concentric rings; the first light-transmitting hole group 70 includes at least one of the first light-transmitting hole 20 and the second light-transmitting hole 21.

[0078] It should be noted that Figure 17 Only four first light-transmitting hole groups 70 are used as an example for description. Figure 18 Only the Figure 17 Two first light-transmitting hole groups 70 on the periphery of the .

[0079] The first light transmission hole group 70 formed by at least one of the first light transmission holes 20 and the second light transmission holes 21 is arranged in a ring, and the radius of each first light transmission hole group 70 is different. From the first display area AB to the second display area AA, the diameter of the first light transmission hole group 70 increases successively. A first light transmission hole group 70 can include only a plurality of first light transmission holes 20 or only a plurality of second light transmission holes 21, such as Figure 16or a first light-transmitting hole group 70 may include both a first light-transmitting hole 20 and a second light-transmitting hole 21, as shown; Figure 19 When the first light-transmitting hole group 70 is arranged in a ring shape, diffraction of external light when passing through the plurality of first light-transmitting holes 20 and second light-transmitting holes 21 can be further avoided, thereby improving the imaging quality of the camera on the backlight side of the display panel and opposite to the first display area AA.

[0081] In this embodiment, the first display area AB also includes multiple third light-transmitting holes 22, and the areas of all third light-transmitting holes 22 are equal. External light enters the camera disposed on the backlight side of the display panel through the multiple first light-transmitting holes 20, the multiple second light-transmitting holes 21, and the multiple third light-transmitting holes 22, ensuring that the camera receives sufficient light to meet its imaging function. Furthermore, because the third light-transmitting holes 22 are non-rectangular, diffraction of external light passing through the multiple third light-transmitting holes 22 can be avoided, thereby improving the imaging quality of the camera on the backlight side of the display panel, opposite the first display area AA. The sum of the areas of the third light-transmitting holes 22 per unit area (S5) in the first sub-display area BB and the sum of the areas of the third light-transmitting holes 22 per unit area (S6) in the second sub-display area BC can be equal or different, and this embodiment does not specifically limit this. However, in the first sub-display area BB, the sum of the areas of the first light-transmitting hole 20, the second light-transmitting hole 21, and the third light-transmitting hole 22 per unit area is S1+S3+S5; in the second sub-display area BC, the sum of the areas of the first light-transmitting hole 20 and the second light-transmitting hole 21 per unit area is S2+S4+S6, where S1+S3+S5=S2+S4+S6, i.e., the transmittance of the first sub-display area BB and the second sub-display area BC are the same, thereby improving the uniformity of the transmittance of the first display area AB, effectively preventing diffraction of light when passing through the first light-transmitting hole 20, the second light-transmitting hole 21, and the third light-transmitting hole 22, and improving the imaging quality.

[0082] Optional, Figure 21 yes Figure 20 See the schematic diagram of the structure of the two second light-transmitting hole groups in Figure 20 and Figure 21 The display panel includes multiple second light-transmitting hole groups 80; each second light-transmitting hole group 80 is arranged in a ring shape; multiple second light-transmitting hole groups 80 are arranged in concentric rings; the second light-transmitting hole group 80 includes at least one of the first light-transmitting hole 20, the second light-transmitting hole 21 and the third light-transmitting hole 22.

[0083] It should be noted that Figure 20 Only four second light-transmitting hole groups 80 are used as an example for description. Figure 21 Only the Figure 20 Two second light-transmitting hole groups 80 on the periphery.

[0084] The second light-transmitting hole group 80, which comprises at least one of the first light-transmitting hole 20, the second light-transmitting hole 21, and the third light-transmitting hole 22, is arranged in a ring, and each second light-transmitting hole group 80 has a different radius. The diameter of the second light-transmitting hole group 80 increases in a direction from the first display area AB to the second display area AA. A second light-transmitting hole group 80 may include only one of the first light-transmitting hole 20, the second light-transmitting hole 21, and the third light-transmitting hole 22; or a second light-transmitting hole group 80 may include two of the first light-transmitting hole 20, the second light-transmitting hole 21, and the third light-transmitting hole 22; or a second light-transmitting hole group 80 may include all of the first light-transmitting hole 20, the second light-transmitting hole 21, and the third light-transmitting hole 22, which is not specifically limited in this embodiment. When the second light-transmitting hole group 80 is arranged in a ring shape, it can further prevent the external light from diffracting when passing through the multiple first light-transmitting holes 20, the second light-transmitting holes 21 and the third light-transmitting holes 22, thereby improving the imaging quality of the camera located on the backlight side of the display panel and corresponding to the first display area AA.

[0085] It can be understood that the circular arrangement of the second light-transmitting hole group 80 can further prevent diffraction of external light passing through the multiple first light-transmitting holes 20, second light-transmitting holes 21, and third light-transmitting holes 22. The light-emitting elements 10 in the first display area AB are arranged in an array. In a direction perpendicular to the plane of the first base substrate 30, the first light-transmitting holes 20, second light-transmitting holes 21, and third light-transmitting holes 22 do not overlap with the light-emitting units 10. Considering that the diameter of the second light-transmitting hole group 80 increases in the direction from the first display area AB to the second display area AA, the only way to achieve a circular arrangement of the light-transmitting hole group while preventing overlap between the light-transmitting holes and the light-emitting elements 10 is to modify the area of ​​the light-transmitting holes so that each light-transmitting hole is located within the circular arrangement of the light-transmitting hole group. This ensures that the light-transmitting hole group of all light-transmitting holes is arranged in a circular manner, and that the sum of the areas of all light-transmitting holes per unit area in the first sub-display area is equal to the sum of the areas of all light-transmitting holes per unit area in the second sub-display area. Therefore, the display panel may further include multiple fourth light transmission holes, fifth light transmission holes, etc., wherein the areas of one type of light transmission holes are the same, such as the areas of the multiple fourth light transmission holes are the same, and the areas of the multiple fifth light transmission holes are also the same, but the areas of different types of light transmission holes are different, such as the area of ​​the first light transmission hole is larger than the area of ​​the second light transmission hole, and the area of ​​the second light transmission hole is larger than the area of ​​the third light transmission hole. However, this embodiment does not specifically limit this, as long as the light transmission hole group is arranged in a ring, and the sum of the areas of all light transmission holes per unit area in the first sub-display area is equal to the sum of the areas of all light transmission holes per unit area in the second sub-display area.
