Abstract
Description
Technical Field
[0001] This application relates to the field of display technology, and more particularly to a display panel and display device. Background Technology
[0002] Organic light-emitting diode (OLED) devices, as the core of the next generation of display and lighting technologies, have been widely used in smartphones, televisions, wearable devices and other fields due to their advantages such as self-illumination, high contrast, wide viewing angle, and ultra-thin flexibility.
[0003] Currently, some customers of OLED display panels have raised privacy concerns, meaning they want a clear and bright display when viewed from a direct angle, but for others to see the content from other angles. The mainstream solution is to use privacy screen protectors (passive privacy protection). However, privacy screen protectors themselves introduce numerous display problems, such as reduced brightness, changes in color and contrast, etc., affecting the user experience. Therefore, active privacy protection products that can switch between privacy and normal display modes at any time are more attractive to consumers.
[0004] However, current active privacy screen products have added more light-blocking layers to control the viewing angle range, which results in lower transmittance of the display panel. Summary of the Invention

Detailed Implementation
[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0030] Please refer to Figure 1 This application provides a display panel, which includes a plurality of pixel units 10 and a plurality of light-shielding portions 20; the plurality of pixel units 10 are arranged along a first direction X and a second direction Y, the first direction X and the second direction Y intersect, and each pixel unit 10 has at least two sub-pixels 101; the plurality of light-shielding portions 20 are disposed on the light-emitting side of the plurality of pixel units 10, the plurality of light-shielding portions 20 are arranged along the first direction X, and the light-shielding portions 20 extend along the second direction Y; in the thickness direction of the display panel, the plurality of light-shielding portions 20 are located between the plurality of sub-pixels 101 in the plurality of pixel units 10.
[0031] The plurality of pixel units 10 include a first pixel unit 11 and a second pixel unit 12. The distance between the sub-pixel 101 in the first pixel unit 11 and the edge of the light-shielding part 20 near the sub-pixel 101 along the first direction X is greater than the distance between the sub-pixel 101 in the second pixel unit 12 and the edge of the light-shielding part 20 near the sub-pixel 101 along the first direction X. An opening 201 is formed in the light-shielding part 20, and the opening 201 does not overlap with the second pixel unit 12 along the first direction X.
[0032] In the implementation process, this embodiment of the application increases the light-transmitting area of the light-shielding part 20 by forming an opening 201 in the light-shielding part 20, thereby improving the transmittance of the display panel; furthermore, the distance between the sub-pixel 101 in the first pixel unit 11 and the edge of the light-shielding part 20 near the sub-pixel 101 along the first direction X is greater than the distance between the sub-pixel 101 in the second pixel unit 12 and the edge of the light-shielding part 20 near the sub-pixel 101 along the first direction X. Therefore, the first pixel unit 11 can achieve light emission from a wider viewing angle, while the second pixel unit 12... The two-pixel unit 12 can achieve light emission from a smaller viewing angle, meaning the second pixel unit 12 can be used for privacy display. In this application, by setting the opening 201 and the second pixel unit 12 to not overlap along the first direction X, the probability that the light-shielding part 20 will block the light emission angle of the second pixel unit 12 due to the formation of the opening 201 can be reduced. This reduces the probability that the second pixel unit 12 will emit more light at the opening 201 of the light-shielding part 20 during privacy display, thereby enabling the display panel to simultaneously achieve high transmittance and good privacy performance.
[0033] It should be noted that the distance between the pixel unit 10 and the light-shielding part 20 along the first direction X can be regarded as the distance between the edge of the pixel unit 10 near the light-shielding part 20 and the edge of the light-shielding part 20 near the pixel unit 10 along the first direction X.
[0034] Furthermore, the positional and dimensional relationships between the light-shielding portion 20 and the pixel unit 10 in the first direction X and the second direction Y in the embodiments of this application are obtained from a top view.
[0035] Specifically, please refer to Figure 1 and Figure 2 The display panel includes an array substrate, a plurality of pixel units 10 disposed on the array substrate, and a functional film layer disposed on the light-emitting side of the plurality of pixel units 10.
[0036] In some embodiments, the array substrate includes a substrate 30 and a driving circuit layer 40 disposed on the substrate 30.
[0037] In some embodiments, substrate 30 may be a rigid substrate, such as a glass substrate; or substrate 30 may be a flexible substrate, such as a substrate formed of polyimide. When substrate 30 is a flexible substrate, substrate 30 may be formed of multiple sub-substrates of the same material, such as polyimide, and adjacent sub-substrates may be bonded together by adhesive sub-layers.
[0038] In some embodiments, the driving circuit layer 40 includes a plurality of thin-film transistors, capacitors, and signal lines arranged in an array; and the plurality of thin-film transistors, capacitors, and signal lines can be used to form a driving circuit for driving the display panel to display, such as a gate driving circuit, a pixel driving circuit, etc.

[0042] In some embodiments, the display panel further includes a pixel definition layer 13 and a light-emitting functional layer disposed on the anode layer; wherein, the pixel definition layer 13 has a plurality of pixel openings, and the plurality of pixel openings are disposed corresponding to a plurality of anodes, and the light-emitting functional layer includes a plurality of sub-pixels 101 disposed in the plurality of pixel openings, each sub-pixel 101 being located in the corresponding pixel opening and on the anode at the bottom of the corresponding pixel opening.
[0043] Furthermore, the display panel also includes a cathode layer disposed on the pixel definition layer 13 and the light-emitting functional layer, and a plurality of sub-pixels 101 within the plurality of pixel openings covered by the cathode layer and the pixel definition layer 13; wherein, the anode can transfer holes to the sub-pixels, the cathode layer can transfer electrons to the sub-pixels, and the holes and electrons can recombine in the sub-pixels 101 to excite light, so as to realize the light emission of the sub-pixels 101.
[0044] It should be noted that the multiple sub-pixels 101 in the embodiments of this application can emit light of different colors, and at least two sub-pixels 101 with different emission colors can constitute a pixel unit 10; that is, the display panel includes multiple pixel units 10 disposed on the driving circuit layer 40, and each pixel unit 10 has at least two sub-pixels 101 with different emission colors.
[0045] In some embodiments, the display panel further includes an encapsulation layer 50 disposed on the side of the plurality of pixel units 10 away from the driving circuit layer 40. The encapsulation layer 50 covers the plurality of pixel units 10 (the plurality of sub-pixels 101) and the cathode layer to protect the plurality of sub-pixels 101 and block moisture.
[0046] In some embodiments, the encapsulation layer 50 may include a first inorganic encapsulation layer 51, an organic encapsulation layer 52, and a second inorganic encapsulation layer 53 sequentially stacked on the cathode layer; wherein the first inorganic encapsulation layer 51 and the second inorganic encapsulation layer 53 may be prepared using inorganic materials, such as silicon nitride, silicon oxynitride, aluminum oxide, etc., which can play a role in blocking water and oxygen; while the organic encapsulation layer 52 may be prepared using organic resin materials, such as acrylic resin, epoxy resin, etc., which can play a role in improving flatness and buffering stress.
[0047] In some embodiments, the thickness of the first inorganic encapsulation layer 51 may be greater than or equal to 1 micrometer and less than or equal to 1.5 micrometers; the thickness of the organic encapsulation layer 52 may be greater than or equal to 9 micrometers and less than or equal to 11 micrometers; and the thickness of the second inorganic encapsulation layer 52 may be greater than or equal to 0.6 micrometers and less than or equal to 0.8 micrometers.
[0048] In some embodiments, the display panel may further include a touch layer disposed on the encapsulation layer 50, and the touch layer may include a touch metal layer and an insulating film layer covering and spacing the touch metal layer, wherein the insulating film layer includes a first insulating layer 61 disposed on the encapsulation layer 50 and a second insulating layer 62 disposed on the first insulating layer 61.
[0049] In this embodiment, a viewing angle adjustment layer can be provided on the light-emitting side of multiple pixel units 10 to adjust the light-emitting viewing angle of different pixel units 10, thereby achieving active privacy protection of the display panel.
[0050] In some embodiments, the display panel includes a plurality of light-shielding portions 20 disposed on the light-emitting side of a plurality of pixel units 10, the plurality of light-shielding portions 20 being arranged along a first direction X and extending along a second direction Y; in a top view, the plurality of light-shielding portions 20 are located between a plurality of sub-pixels 101 in the plurality of pixel units 10.
[0051] In some embodiments, the first direction X and the second direction Y are perpendicular to each other.
[0052] The plurality of pixel units 10 include a first pixel unit 11 and a second pixel unit 12. The distance between the sub-pixel 101 in the first pixel unit 11 and the edge of the light-shielding part 20 near the sub-pixel 101 along the first direction X is greater than the distance between the sub-pixel 101 in the second pixel unit 12 and the edge of the light-shielding part 20 near the sub-pixel 101 along the first direction X. Consequently, the distance between the light-shielding part 20 and the second pixel unit 12 is smaller. The light-shielding part 20 has a greater blocking effect on the lateral light emitted by the second pixel unit 12 along the second direction Y. Therefore, compared with the first pixel unit 11, the light emission angle range of the second pixel unit 12 along the second direction Y is smaller, which is beneficial for the display panel to achieve privacy display.
[0053] In some embodiments, the light-shielding part 20 is composed of at least two light-shielding sub-layers. In a top view, the light-shielding part 20 adjacent to the first pixel unit 11 has at least one light-shielding sub-layer, and the light-shielding part 20 adjacent to the second pixel unit 12 has at least two light-shielding sub-layers. This allows for further fine control of the light emission angle range of the second pixel unit 12, achieving a more effective privacy display.
[0054] It is understood that when the display panel provided in this application embodiment is in normal mode (non-peeping mode), the first pixel unit 11 emits light or both the first pixel unit 11 and the second pixel unit 12 emit light, and the light emission angle of the display panel is large; while when the display panel is in peeping mode, the first pixel unit 11 does not emit light, while the second pixel unit 12 emits light, and the light emission angle of the display panel is small.
[0055] Specifically, the light-shielding part 20 includes a first light-shielding sub-layer 23 and a second light-shielding sub-layer 24 disposed on the side of the first light-shielding sub-layer 23 away from the plurality of pixel units 10; wherein, the display panel also includes at least two spacer layers, at least one spacer layer disposed between the touch layer and the first light-shielding sub-layer 23, and at least one spacer layer disposed between the first light-shielding sub-layer 23 and the second light-shielding sub-layer 24.
[0056] In some embodiments, at least two spacer layers include a first spacer layer 71 disposed on the second insulating layer 62, a second spacer layer 72 disposed on the first light-shielding sub-layer 23, and a third spacer layer 73; wherein the first light-shielding sub-layer 23 is disposed on the first spacer layer 71, the second light-shielding sub-layer 24 is disposed on the side of the first light-shielding sub-layer 23 away from the first spacer layer 71, the second spacer layer 72 covers the first light-shielding sub-layer 23, the third spacer layer 73 is disposed on the side of the second spacer layer 72 away from the first light-shielding sub-layer 23, and the second light-shielding sub-layer 24 is disposed on the side of the third spacer layer 73 away from the second spacer layer 72.
[0057] In some embodiments, the materials of the first spacer layer 71, the second spacer layer 72, and the third spacer layer 73 can all be selected from organic materials, such as organic resin materials. The first spacer layer 71, the second spacer layer 72, and the third spacer layer 73 can improve the flatness of the film layer and adjust the spacing between the pixel unit 10 and the first light-shielding sub-layer 23, as well as the spacing between the first light-shielding sub-layer 23 and the second light-shielding sub-layer 24. By adjusting the spacing between the pixel unit 10 and the first light-shielding sub-layer 23, as well as the spacing between the first light-shielding sub-layer 23 and the second light-shielding sub-layer 24, the light-shielding part 20 can control the range of the light emission angle of the pixel unit 10.
[0058] It should be noted that the light-shielding part 20 in this embodiment can be formed by two light-shielding layers. The first light-shielding sub-layer 23 and the second light-shielding sub-layer 24 can both be located above the second pixel unit 12. The first light-shielding sub-layer 23 is closer to the second pixel unit 12 than the second light-shielding sub-layer 24, so the first light-shielding sub-layer 23 can block the light emitted from the second pixel unit 12 at a wide viewing angle. The second light-shielding sub-layer 24 is farther away from the second pixel unit 12, so the second light-shielding sub-layer 24 can further block the light emitted from the second pixel unit 12 at a narrow viewing angle, thereby further reducing the light emission angle range of the second pixel unit 12 and achieving effective privacy protection for the display panel.
[0059] In some embodiments, both the first light-shielding sublayer 23 and the second light-shielding sublayer 24 can be black matrices, and the light-shielding part 20 in this embodiment is not limited to black matrices, but can also be other light-shielding materials, which are not specifically limited here.
[0060] In some embodiments, the thickness of the first light-shielding sublayer 23 is greater than or equal to 0.9 micrometers and less than or equal to 1.2 micrometers; the thickness of the second light-shielding sublayer 24 may be the same as the thickness of the first light-shielding sublayer 23, or it may be greater than or less than the thickness of the first light-shielding sublayer 23.
[0061] In some embodiments, to ensure privacy protection while reducing light leakage between the first light-blocking sub-layer 23 and the second light-blocking sub-layer 24, the distance between the first light-blocking sub-layer 23 and the second light-blocking sub-layer 24 can be designed to improve privacy protection and reduce light leakage. Specifically, the thickness of the second spacer layer 72 is greater than or equal to 4 micrometers and less than or equal to 5 micrometers; the thickness of the third spacer layer 73 is greater than or equal to 3 micrometers and less than or equal to 4 micrometers; further, the sum of the thicknesses of the second spacer layer 72 and the third spacer layer 73 can be greater than or equal to 7 micrometers and less than or equal to 9 micrometers.
[0062] In some embodiments, the display panel further includes a cover layer 74 disposed on the second spacer layer 72 and covering the second light-shielding sublayer 24 to improve the flatness of the film layer.
[0063] In some embodiments, the thickness of the cover layer 74 may be greater than or equal to 3 micrometers and less than or equal to 5 micrometers.
[0064] Furthermore, this application embodiment describes the arrangement of the light-shielding part 20 with respect to the arrangement of the pixel units 10 in the specific embodiments.
[0065] In one specific embodiment of this application, please refer to Figure 1The pixel unit 10 has a first sub-pixel 1011, a second sub-pixel 1012 and a third sub-pixel 1013. The light emission colors of the first sub-pixel 1011, the second sub-pixel 1012 and the third sub-pixel 1013 are all different.
[0066] For example, the first sub-pixel 1011 emits green light, the second sub-pixel 1012 emits red light, and the third sub-pixel 1013 emits blue light; and the area of the third sub-pixel 1013 is larger than the area of the first sub-pixel 1011, and the area of the third sub-pixel 1013 is larger than the area of the second sub-pixel 1012, in order to improve the luminous efficiency and lifespan of the blue sub-pixel.
[0067] In each pixel unit 10, the first sub-pixel 1011 and the second sub-pixel 1012 are arranged along the second direction Y, while the third sub-pixel 1013 is located on one side of the first sub-pixel 1011 and the second sub-pixel 1012 along the first direction X.
[0068] In some embodiments, among the plurality of pixel units 10 arranged along the first direction X, the first pixel unit 11 and the second pixel unit 12 are arranged alternately, that is, a second pixel unit 12 is disposed between two adjacent first pixel units 11 along the first direction X, and a first pixel unit 11 is disposed between two adjacent second pixel units 12 along the first direction X.
[0069] In some embodiments, among the plurality of pixel units 10 arranged along the second direction Y, the first pixel unit 11 and the second pixel unit 12 are arranged alternately, that is, a second pixel unit 12 is disposed between two adjacent first pixel units 11 along the second direction Y, and a first pixel unit 11 is disposed between two adjacent second pixel units 12 along the second direction Y.
[0070] In some embodiments, in the plurality of first pixel units 11 and the plurality of second pixel units 12 arranged along the second direction, the arrangement of sub-pixels 101 in each first pixel unit 11 and the arrangement of sub-pixels 101 in each second pixel unit 12 can be the same.
[0071] Furthermore, among the multiple pixel units 10 arranged along the second direction Y, multiple first sub-pixels 1011 and multiple second sub-pixels 1012 are arranged along the second direction Y to form a first column, and multiple third sub-pixels are arranged along the second direction Y to form a second column. The first column and the second column are adjacent along the first direction X. It should be noted that the first column and the second column being adjacent does not mean that they will be connected together. Rather, the first column and the second column are still set at intervals, but no other sub-pixels 101 are set between the first column and the second column.
[0072] In some embodiments, between two adjacent pixel units 10 along the first direction X, in one pixel unit 10, the overlap length of the third sub-pixel 1013 and the second sub-pixel 1012 along the first direction X is greater than the overlap length of the third sub-pixel 1013 and the first sub-pixel 1011 along the first direction X; in the other pixel unit 10, the overlap length of the third sub-pixel 1013 and the second sub-pixel 1012 along the first direction X is less than the overlap length of the third sub-pixel 1013 and the first sub-pixel 1011 along the first direction X. That is, in the embodiments of this application, the two adjacent third sub-pixels 1013 arranged along the first direction X are partially misaligned, that is, the two adjacent third sub-pixels 1013 only partially overlap along the first direction X.
[0073] It should be noted that, as Figure 1 As shown, in this embodiment, the spacing between some adjacent third sub-pixels 1013 along the second direction Y can be increased, which is beneficial for setting support pillars between the two adjacent third sub-pixels 1013. The support pillars are set on the pixel definition layer and can be used to support the mask in the vapor deposition process of the sub-pixel 101. In this embodiment, by differentiating the distribution of the third sub-pixels 1013, the uniformity of the distribution of the support pillars can be improved, the support of the support pillars can be improved, the uniformity of the force on the display panel in the vapor deposition process of the sub-pixel 101 can be improved, and the yield of the display panel can be improved.
[0074] Furthermore, the plurality of light-shielding parts 20 include a first light-shielding part 21 and a second light-shielding part 22. The first light-shielding part 21 is disposed between adjacent pixel units 10 along the first direction X, and the second light-shielding part 22 passes through the plurality of pixel units 10 arranged along the second direction Y and is adjacent to the sub-pixel 101 in the pixel unit 10.
[0075] In some embodiments, among the plurality of pixel units 10 arranged along the second direction Y, a plurality of first sub-pixels 1011 and a plurality of second sub-pixels 1012 are arranged along the second direction Y to form a first column, and a plurality of third sub-pixels 1013 are arranged to form a second column. The first column and the second column are adjacent along the first direction X, and the second light-shielding part 22 is disposed between the adjacent first column and the second column.
[0076] As can be seen, a plurality of pixel units 10 arranged along the second direction Y are provided between two adjacent first light-shielding parts 21 along the first direction X, and a first column of first sub-pixels 1011 and second sub-pixels 1012 or a second column of third sub-pixels 1013 are provided between adjacent first light-shielding parts 21 and second light-shielding parts 22 along the second direction Y.
[0077] In this embodiment, the spacing between the light-shielding part 20 and different pixel units 10 is designed so that the light-shielding part 20 blocks the lateral light emitted by different pixel units 10 to different degrees, thereby achieving different light emission angle ranges for different pixel units 10.
[0078] In some embodiments, in a top view, the light-shielding portion 20 is disposed between adjacent pixel units 10 along the first direction X, and the light-shielding portion 20 passes through a plurality of pixel units 10 arranged along the second direction Y, and is adjacent to the sub-pixels 101 in the pixel unit 10.
[0079] Wherein, there is a first spacing L1 or a second spacing L2 between adjacent first light-shielding parts 21 along the first direction X, and there is a third spacing L3 or a fourth spacing L4 between adjacent first light-shielding parts 21 and second light-shielding parts 22 along the first direction X, wherein the first spacing L1 is greater than the second spacing L2, and the third spacing L3 is greater than the fourth spacing L4.
[0080] A first pixel unit 11 is disposed between two adjacent first light-shielding parts 21 with a first spacing L1, and a second pixel unit 12 is disposed between two adjacent first light-shielding parts 21 with a second spacing L2.
[0081] A portion of a sub-pixel 101 in the first pixel unit 11 is disposed between adjacent first light-shielding portions 21 and second light-shielding portions 22 having a third spacing L3, and a portion of a sub-pixel in the second pixel unit 12 is disposed between adjacent first light-shielding portions 21 and second light-shielding portions 22 having a fourth spacing L4.
[0082] In other words, the pixel unit 10 with a smaller distance between sub-pixel 101 and light-shielding part 20 is the second pixel unit 12, which is the privacy pixel; the pixel unit 10 with a larger distance between sub-pixel 101 and light-shielding part 20 is the first pixel unit 11, which is the wide-viewing-angle display pixel, which can be used for normal display.
[0083] In some embodiments, the display panel is configured in a privacy mode, where the first pixel unit 11 does not emit light and the second pixel unit 12 emits light; or in a non-privacy mode, at least the first pixel unit 11 emits light; that is, when the display panel is configured in a non-privacy mode, only the first pixel unit 11 may emit light, or the first pixel unit 11 and the second pixel unit 12 may emit light simultaneously.
[0084] Specifically, the first light-shielding part 21 can be provided with multiple bending segments as it extends along the second direction Y, so that the spacing between two adjacent first light-shielding parts 21 along the first direction X can be set differently; for example, the area with a larger spacing between two adjacent first light-shielding parts 21 along the first direction X is the first region 2021, and the area with a smaller spacing between two adjacent first light-shielding parts 21 along the first direction X is the second region 2022; that is, the spacing between two adjacent first light-shielding parts 21 along the first direction X in the first region 2021 is greater than the spacing between two adjacent first light-shielding parts 21 along the first direction X in the second region 2022.
[0085] Correspondingly, the first pixel unit 11 is disposed in the first region 2021, and the second pixel unit 12 is disposed in the second region 2022, thereby making the distance between the first pixel unit 11 and the first light-shielding part 21 in the first region 2021 along the first direction X greater than the distance between the second pixel unit 12 and the first light-shielding part 21 in the second region 2022 along the first direction X.
[0086] Furthermore, the second light-shielding part 22 has multiple line segments with different widths as it extends along the second direction Y. For example, the second light-shielding part 22 includes a first line segment 221 and a second line segment 222, and the first line segment 221 and the second line segment 222 are connected. The width of the first line segment 221 along the first direction X is smaller than the width of the second line segment 222 along the first direction X.
[0087] In the top view, the first line segment 221 passes through the first pixel unit 11, and the second line segment 222 passes through the second pixel unit 12. As a result, the distance between the first sub-pixel 1011 and the first line segment 221 in the first pixel unit 11 is greater than the distance between the first sub-pixel 1011 and the second line segment 222 in the second pixel unit 12; the distance between the second sub-pixel 1012 and the first line segment 221 in the first pixel unit 11 is greater than the distance between the second sub-pixel 1012 and the second line segment 222 in the second pixel unit 12.
[0088] Similarly, the distance between the third sub-pixel 1013 and the first line segment 221 in the first pixel unit 11 is greater than the distance between the third sub-pixel 1013 and the second line segment 222 in the second pixel unit 12; thus, the light-shielding part 20 can effectively limit the light emission angle range of the second pixel unit 12, thereby improving the privacy display effect of the display panel.
[0089] In some embodiments, since the plurality of pixel units 10 arranged along the second direction Y are arranged alternately as first pixel unit 11 and second pixel unit 12, the first region 2021 and the second region 2022 in the first light-shielding part 21 are also arranged alternately along the second direction Y, and the first line segment 221 and the second line segment 222 in the second light-shielding part 22 are also arranged alternately along the second direction Y.
[0090] Furthermore, the light-shielding part 20 has two light-shielding layers, and the differentiated setting of the number of light-shielding layers in the first light-shielding part 21 and the second light-shielding part 22 in the embodiments of this application is to further improve the privacy display effect of the display panel.
[0091] The first light-shielding portion 21 has a first light-shielding sub-layer 23 and a second light-shielding sub-layer 24. In the top view, the second light-shielding portion 22 passing through the first pixel unit 11 has a first light-shielding sub-layer 23, meaning that the second light-shielding portion 22 partially overlaps with the first pixel unit 11 along the thickness direction of the display panel. Similarly, the second light-shielding portion 22 passing through the second pixel unit 12 has a first light-shielding sub-layer 23 and a second light-shielding sub-layer 24, meaning that the second light-shielding portion 22 partially overlaps with the second pixel unit 12 along the thickness direction of the display panel. The light-shielding part 22 has a first light-shielding sub-layer 23 and a second light-shielding sub-layer 24; that is, in this embodiment, the first light-shielding part 21 between different pixel units 10 is set as two layers, which can effectively prevent light crosstalk and light leakage; while the second light-shielding part 22 in the first pixel unit 11 is set as one layer, which can reduce the light emission of the light-shielding part 20 to the first pixel unit 11 at a large viewing angle; the second light-shielding part 22 in the second pixel unit 12 is set as two layers, which can increase the light-shielding effect of the light-shielding part 20 on the light emission of the second pixel unit 12 at a large viewing angle, and improve the privacy display effect of the display panel.
[0092] In some embodiments, the first line segment 221 contains only the first light-shielding sub-layer 23, while the first light-shielding portion 21 and the second line segment 222 both contain the first light-shielding sub-layer 23 and the second light-shielding sub-layer 24.
[0093] Please refer to Figure 1 and Figure 2 For the first pixel unit 11, the first light-shielding sub-layer 23 forms a first opening 231 above the pixel opening, and the width of the first opening 231 is greater than the width of the pixel opening; wherein, the width of the first opening 231 can be regarded as the distance between adjacent first light-shielding parts 21 and second light-shielding parts 22 in the first region 2021 along the first direction X.
[0094] In some embodiments, the edge of the first opening 231 extends outward by a distance of 3 to 5 micrometers relative to the edge of the pixel opening of the first pixel unit 11 in a direction away from the first opening 231.
[0095] For the second pixel unit 12, the first light-shielding sub-layer 23 forms a second opening 232 above the pixel opening, and the width of the second opening 232 is greater than the width of the pixel opening; wherein, the width of the second opening 232 can be regarded as the distance between adjacent first light-shielding portions 21 and second light-shielding portions 22 in the second region 2022 along the first direction X.
[0096] In some embodiments, the edge of the second opening 232 extends outward by a distance of 1 micrometer to 1.5 micrometers relative to the edge of the pixel opening of the first pixel unit 11 in a direction away from the second opening 232. Considering the light leakage of the second pixel unit 12 between the first light-shielding sub-layer 23 and the second light-shielding sub-layer 24, the width of the second opening 232 is made smaller than the width of the first opening 231, thereby effectively reducing the light leakage of the second pixel unit 12 between the first light-shielding sub-layer 23 and the second light-shielding sub-layer 24.
[0097] The second light-shielding sublayer 24 forms a third opening 241 above the second opening 232, and the width of the third opening 241 can be greater than, equal to or less than the width of the second opening 232; while the width of the second light-shielding sublayer 24 along the first direction X can be greater than or equal to 6 micrometers and less than or equal to 8 micrometers.
[0098] It should be noted that since the display panel provided in this application embodiment has a large number of light-shielding parts 20, it is easy to cause insufficient transmittance of the display panel. Therefore, this application embodiment also makes a special design on the structure of the light-shielding parts 20 to improve the transmittance of the display panel.
[0099] Specifically, an opening 201 is formed in the light-shielding part 20, and the opening 201 does not overlap with the second pixel unit 12 along the first direction X. This application embodiment increases the light-transmitting area of the light-shielding part 20 by forming an opening 201 in the light-shielding part 20, thereby improving the transmittance of the display panel. Furthermore, the distance between the sub-pixel 101 in the first pixel unit 11 and the edge of the light-shielding part 20 near the sub-pixel 101 along the first direction X is greater than the distance between the sub-pixel 101 in the second pixel unit 12 and the edge of the light-shielding part 20 near the sub-pixel 101 along the first direction X. Therefore, the first pixel unit 11 can achieve light emission from a larger viewing angle, while the second pixel unit 12 can achieve light emission from a smaller viewing angle, that is, the second pixel unit 12 can be used for privacy display. In this application, by setting the opening 201 and the second pixel unit 12 to not overlap along the first direction X, the probability that the light-shielding part 20 will block the light emission angle of the second pixel unit 12 due to the formation of the opening 201 can be reduced, and the probability of the second pixel unit 12 emitting more light at the opening 201 of the light-shielding part 20 during privacy display can be reduced, thereby ensuring the privacy performance of the display panel.
[0100] Furthermore, in some embodiments, the opening 201 does not overlap with the first pixel unit 11 along the first direction X.
[0101] It should be noted that the shape of the opening 201 in the display panel provided in this application embodiment can be varied; for example, if the light-shielding portion 20 is partitioned along the second direction Y to form the opening 201, then the two sides of the opening 201 along the second direction Y are the edges of the light-shielding portion 20, and the two sides of the opening 201 along the first direction X are not surrounded by the light-shielding portion 20, such as... Figure 1 As shown; or, the light-shielding part 20 surrounds or partially surrounds the opening 201, as shown. Figure 3 As shown.
[0102] As mentioned above, among the multiple pixel units 10 arranged along the second direction Y, the first pixel unit 11 and the second pixel unit 12 are arranged alternately; and the orthographic projection of the opening 201 along the first direction X is located between the adjacent first pixel unit 11 and second pixel unit 12 along the second direction Y, which can simultaneously avoid the setting of the opening 201 affecting the light emission of the first pixel unit 11 and the light emission of the second pixel unit 12.
[0103] In some embodiments, an opening 201 is formed in the second light-shielding portion 22, that is, in this embodiment, the opening 201 is formed in a plurality of pixel units 10 arranged along the second direction Y, so as to effectively improve the transmittance of the display panel.
[0104] In some embodiments, each second light-shielding part 22 may have an opening 201 at a position between the corresponding first pixel unit 11 and the second pixel unit 12, or some of the second light-shielding parts 22 may have an opening 201 at a position between the corresponding first pixel unit 11 and the second pixel unit 12; and the openings 201 may be evenly distributed in the display panel, or may be differentiated according to the light transmittance requirements. For example, in positions with higher light transmittance requirements, the distribution density of the openings 201 is greater, while in positions with lower light transmittance requirements, the distribution density of the openings 201 is smaller.
[0105] It should be noted that in the embodiments of this application, the light-shielding portions 20 all extend along the second direction Y, and the opening 201 can be a blank area formed by the light-shielding portion 20 being interrupted along its extension path; such as Figure 1 As shown; or, the opening 201 may be an opening formed on the extension path of the light-shielding portion 20 and surrounded or partially surrounded by the light-shielding portion 20, such as... Figure 3 As shown.
[0106] In some embodiments, the length of the opening 201 along the second direction Y is less than or equal to the minimum distance between adjacent first pixel unit 11 and second pixel unit 12 along the second direction Y.
[0107] It is understood that this embodiment improves the transmittance of the display panel by providing an opening 201 in the light-shielding part 20. However, since the light-shielding part 20 is arranged adjacent to the pixel unit 10, and also adjacent to the first pixel unit 11 and the second pixel unit 12, if the length of the opening 201 is set too large, it is easy for the first pixel unit 11 and the second pixel unit 12 to increase the amount of light emitted at the opening 201 during the light-emitting process, thereby causing the pixel unit 10 to leak light at the opening 201, which affects the display effect of the display panel and reduces the privacy protection effect of the display panel. Therefore, in this embodiment, the length of the opening 201 along the second direction Y is limited so that the opening 201 does not extend into the area where the pixel unit 10 is located, thereby reducing the probability that the light-shielding part 20 will block the light emission angle of the first pixel unit 11 and the second pixel unit 12 due to the formation of the opening 201, reducing the probability that the second pixel unit 12 will increase the light emission at the opening 201 of the light-shielding part 20 during privacy display, thereby ensuring the display effect and privacy protection performance of the display panel.
[0108] Further, please refer to Figure 1 , Figure 4 as well as Figure 5 In some embodiments, a first sub-opening 2011 is provided in the first light-shielding sub-layer 23, and the second light-shielding sub-layer 24 does not overlap with the first sub-opening 2011 along the thickness direction of the display panel to form an opening 201.
[0109] It should be noted that, since the second light-shielding portion 22 passing through the first pixel unit 11 is only composed of the first light-shielding sub-layer 23 and does not have a second light-shielding sub-layer 24, therefore, Figure 4 After the second sub-opening 2012 is formed, the second light-shielding sub-layer 24 does not exist on the left side of the second sub-opening 2012 (the side closer to the first pixel unit 11), thus resulting in the following... Figure 4 The structure shown in the second light-shielding sub-layer 24 is such that the second sub-opening 2012 is adjacent to the second light-shielding sub-layer 24 on one side, while the other side is open and not surrounded by the second light-shielding sub-layer 24.
[0110] In other embodiments, when the opening 201 is a closed opening, and the light-shielding part 20 is located in the area that does not overlap with the pixel unit 10 along the first direction X, the light-shielding part 20 has a first light-shielding sub-layer 23 and a second light-shielding sub-layer 24; then at the location where the opening 201 is formed, a first sub-opening 2011 is formed in the first light-shielding sub-layer 23, and a second sub-opening 2012 is formed in the second light-shielding sub-layer 24, and the first sub-opening 2011 and the second sub-opening 2012 are aligned along the thickness direction of the display panel; and the first sub-opening 2011 and the second sub-opening 2012 constitute the opening 201.
[0111] The first sub-opening 2011 and the second sub-opening 2012 have the same area and can overlap along the thickness direction of the display panel.
[0112] In some embodiments, the length of the first sub-opening 2011 along the second direction Y can be greater than or equal to 15 micrometers and less than or equal to 20 micrometers; more preferably, the length of the first sub-opening 2011 along the second direction Y can be greater than or equal to 8 micrometers and less than or equal to 10 micrometers.
[0113] In some embodiments, the length of the second sub-opening 2012 along the second direction Y can be greater than or equal to 15 micrometers and less than or equal to 20 micrometers; more preferably, the length of the second sub-opening 2012 along the second direction Y can be greater than or equal to 8 micrometers and less than or equal to 10 micrometers.
[0114] As mentioned above, in this embodiment of the application, the transmittance of the display panel is improved by providing an opening 201 in the light-shielding part 20. However, the display panel contains a driving circuit layer 40, and the driving circuit layer 40 is provided with multiple conductive layers. Multiple electrodes, signal lines, etc. are distributed in the conductive layers, which will also block light. Therefore, this embodiment of the application also needs to design the wiring of the conductive layers in the driving circuit layer 40 so that the transmittance of the display panel can be further increased.
[0115] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5 The driving circuit layer 40 includes at least one conductive layer disposed on the substrate. The driving circuit layer 40 includes multiple light-transmitting areas. The conductive layer is disposed outside the light-transmitting areas 401. The opening 201 and at least one light-transmitting area 401 at least partially overlap along the thickness direction of the display panel; thereby effectively improving the transmittance of the display panel.
[0116] It is understood that the driving circuit layer 40 provided in this application embodiment contains multiple conductive layers, and the light-transmitting area 401 in the driving circuit layer 40 does not overlap with the conductive layer. That is, no conductive layer is provided in the light-transmitting area 401, and no electrodes, signal lines or other devices are provided. The light-transmitting area 401 can be used to provide light transmission to the sensor below to achieve the sensing function.
[0117] It should be noted that the area of the opening 201 in this embodiment cannot be too large, otherwise it will affect the light emission from the first pixel unit 11 at a wide viewing angle, thereby affecting the symmetry of the display panel at a wide viewing angle; at the same time, at the location of the opening 201, the light transmitted through the opening 201 will be blocked by the light-shielding part 20 surrounding the opening 201 along the second direction Y, such as Figure 1As shown; therefore, when a sensor is provided below the opening 201, the field of view of the sensor will be limited by the second direction Y, which will affect the reduction of the field of view of the sensor along the second direction Y.
[0118] In some embodiments, at least one opening 201 is provided in each of the plurality of light-shielding portions 20, and the plurality of light-transmitting areas 401 include a first light-transmitting area 4011 and a second light-transmitting area 4012. At least one opening 201 and the first light-transmitting area 4011 have an overlapping portion along the thickness direction of the display panel. The area of the overlapping portion has a first value S1, and the sum of the area of the overlapping portion and the area of the second light-transmitting area 4012 has a second value S2, and S1 / (S1+S2) is less than or equal to 50%. That is, the area of the overlapping portion is less than or equal to the area of the second light-transmitting area 4012. This allows the opening 201 to meet the requirement of improving the transmittance of the display panel while reducing the impact on the sensor's field of view.
[0119] Furthermore, in some embodiments, S1 / (S1+S2) is greater than or equal to 30% to ensure that the display panel has sufficient transmittance.
[0120] In some embodiments, please refer to Figure 1 and Figure 5 The plurality of light-transmitting areas 401 include a first light-transmitting area 4011 that at least partially overlaps with the opening 201. The orthographic projection of the opening 201 on the driving circuit layer 40 covers the first light-transmitting area 4011. That is, the area of the opening 201 is larger than that of the first light-transmitting area 4011, thereby allowing light passing through the first light-transmitting area 4011 of the driving circuit layer 40 to pass through the opening 201 sufficiently, so as to effectively improve the transmittance of the display panel.
[0121] In addition, the plurality of light-transmitting areas 401 also include a plurality of second light-transmitting areas 4012, and the second light-transmitting areas 4012 may be distributed within the plurality of pixel units 10, as well as between adjacent pixel units 10, without being specifically limited here.
[0122] exist Figure 1 In the embodiment shown, the opening 201 is formed by blocking the path of the light-shielding portion 20 extending along the second direction Y; and in the top view, the edge of the second light-shielding sub-layer 24 is recessed inward relative to the edge of the first light-shielding sub-layer 23 toward the center of the light-shielding portion 20.
[0123] In other embodiments of this application, please refer to Figure 6In this embodiment, in the top view, the first light-shielding part 21 is located near the edge of the first pixel unit 11, and the edge of the second light-shielding sub-layer 24 is recessed inward relative to the edge of the first light-shielding sub-layer 23 towards the center of the first light-shielding part 21; the first light-shielding part 21 is located near the edge of the second pixel unit 12, and the edge of the first light-shielding sub-layer 23 is flush with the edge of the second light-shielding sub-layer 24; the second light-shielding part 22, having the first light-shielding sub-layer 23 and the second light-shielding sub-layer 24, is located near the edge of the second pixel unit 12, and the edge of the first light-shielding sub-layer 23 is flush with the edge of the second light-shielding sub-layer 24.
[0124] Therefore, in this embodiment, the second light-shielding sub-layer 24 is located near the edge of the second pixel unit 12, relative to... Figure 1 In the embodiment shown, the light-blocking part 20 is closer to the second pixel unit 12, which can improve the light-blocking effect of the light-blocking part 20 on the light emitted by the second pixel unit 12, further narrow the light emission angle range of the second pixel unit 12, and improve the privacy performance of the display panel.
[0125] Furthermore, in this embodiment, the shape of the first light-transmitting area 4011 can be similar to that of a "toilet"; the second light-shielding part 22 extends along the second direction Y, and partially overlaps with the first light-transmitting area 4011 along the thickness direction of the display panel.
[0126] In some embodiments, the second light-shielding portion 22 is broken at the position of the first light-transmitting area 4011 to form an opening 201, and the first light-transmitting area 4011 is offset relative to the opening 201 in the direction of the second column of sub-pixels 101; the second light-shielding portion 22 that partially overlaps with the first light-transmitting area 4011 contains only the first light-shielding sub-layer 23; and the second light-shielding portion 22 that contains only the first light-shielding sub-layer 23 is a first line segment 221, then the first line segment 221 partially overlaps with the first light-transmitting area 4011 along the thickness direction of the display panel.
[0127] In the top view, the first line segment 221 has a first edge 2211 near the opening 201. The side of the first edge 2211 away from the first light-transmitting area 4011 protrudes relative to the side of the first edge 2211 near the first light-transmitting area 4011, and the side of the first edge 2211 near the first light-transmitting area 4011 forms a slope.
[0128] Furthermore, in other embodiments, in a top view, for the second light-shielding portion 22 located within a first preset region 25 between the first sub-pixel 1011 in the first pixel unit 11 and the second sub-pixel 1012 in the second pixel unit 12, with its orthographic projection along the first direction X: the edge of the second light-shielding portion 22 within the first preset region 25 is recessed inward toward the direction away from the adjacent second column third sub-pixel 1013 at a position close to the first light-transmitting area 4011 to form an opening 201; and the first light-transmitting area 4011 is offset relative to the opening 201 toward the direction of the adjacent second column third sub-pixel 1013.
[0129] The first line segment 221 and the second line segment 222 are connected at the first light-transmitting area 4011, and the first line segment 221 and / or the second line segment 222 partially overlap with the first light-transmitting area 4011 along the thickness direction of the display panel; and the second line segment 222 forms a notch, i.e., an opening 201, near the first light-transmitting area 4011.
[0130] Following on, Figure 6 In the embodiment shown, the first light-transmitting area 4011 is offset relative to the second light-blocking part 22 toward the adjacent second column third sub-pixel 1013, and the second light-blocking part 22 forms a slope or notch on the side close to the adjacent second column sub-pixel 101.
[0131] Furthermore, in the top view, at the second light-shielding portion 22 of the first preset region 25, the second line segment 222 can be extended along the second direction Y toward the first pixel unit 11, such that the distance between the second line segment 222 and the first pixel unit 11 along the second direction Y is less than or equal to the length of the portion of the second line segment 222 extending beyond the second pixel unit 12 along the second direction Y; therefore, since the second line segment 222 has two light-shielding sub-layers, namely the first light-shielding sub-layer 23 and the second light-shielding sub-layer 24, the extended second line segment 222 in the second light-shielding portion 22 of the first preset region 25 can extend along the second sub-pixel 1012 in the second pixel unit 12 toward... Figure 6 The light emitted from the lower right corner is effectively blocked, and the second sub-pixel 1012 is used to emit red light to prevent the display panel from showing a pinkish tint during privacy display.
[0132] Additionally, please refer to Figure 7 In another embodiment of this application, with Figure 6The difference in the illustrated embodiment is that, for the second light-shielding portion 22 located in the second preset region 26 between the second sub-pixel 1012 in the first pixel unit 11 and the first sub-pixel 1011 in the second pixel unit 12, as projected orthogonally along the first direction X: the first line segment 221 extends toward the second line segment 222, the second line segment 222 extends toward the first line segment 221, and the first line segment 221 and the second line segment 222 are connected; since the second line segment 222 has two light-shielding sub-layers, namely the first light-shielding sub-layer 23 and the second light-shielding sub-layer 24, the extended second line segment 222 in the second light-shielding portion 22 within the second preset region 26 can provide light protection for the first sub-pixel 1011 in the second pixel unit 12 as it projects toward the first sub-pixel 1011. Figure 7 The light emitted from the upper right corner is effectively blocked, and the first sub-pixel 1011 is used to emit green light to prevent the display panel from turning green during the privacy display process.
[0133] Furthermore, in some embodiments, at the second light-shielding portion 22 of the second preset region 26, the width of the second line segment 222 on the side close to the first line segment 221 gradually decreases to form two inclined sides. The inclined side on the side close to the first light-transmitting area 4011 can avoid the first light-transmitting area 4011, while the inclined side on the side away from the first light-transmitting area 4011 can correspond to the inclined side formed by bending the adjacent first light-shielding portion 21, so as to improve the symmetry of light shielding and thus improve the uniformity of light output.
[0134] In this embodiment of the application, at least one conductive layer includes a plurality of functional signal lines 41, and the plurality of functional signal lines 41 intersect to form a first light-transmitting area 4011.
[0135] In this process, at least some of the functional signal lines 41 bend at the edge of the first light-transmitting area 4011 toward the center of the first light-transmitting area 4011 to avoid the first light-transmitting area 4011, thereby increasing the area of the first light-transmitting area 4011 and improving the transmittance of the display panel.
[0136] In some embodiments, the orthographic projection of the edge of each functional signal line 41 near the first light-transmitting area 4011 along the thickness direction of the display panel is located within the opening 201, so that the opening 201 can completely cover the first light-transmitting area 4011 and improve the transmittance of the display panel.

[0144] In some embodiments, please refer to Figure 1 , Figure 8 and Figure 9 The functional signal line 41 includes a compensation control signal line 93, a data signal line 91, a second reset signal line 96, a reset signal auxiliary line 912, and an anode connection line 913.
[0145] Among them, the compensation control signal line 93, the data signal line 91, the second reset signal line 96, the reset signal auxiliary line 912, and the anode connection line 913 intersect to form the first light-transmitting area 4011.
[0146] The second reset signal line 96 includes a first reset sub-line 9601 and a second reset sub-line 9602 connected to different color sub-pixels 101. Both the first reset sub-line 9601 and the second reset sub-line 9602 extend along the first direction X. However, the first reset sub-line 9601 is positioned closer to the first light-transmitting area 4011 than the second reset sub-line 9602.
[0147] In some embodiments, the first reset sub-line 9601 can be connected to the pixel driving circuit 80 corresponding to the sub-pixel 101 with light emission colors of blue and green, while the second reset sub-line 9602 can be connected to the pixel driving circuit 80 corresponding to the sub-pixel 101 with light emission color of red.
[0148] Both the compensation control signal line 93 and the first reset sub-line 9601 extend along the first direction X and are distributed on opposite sides of the first light-transmitting area 4011 along the second direction Y.
[0149] The data signal line 91 includes a first data signal line 9101 and a second data signal line 9102 connected to sub-pixels of different colors 101. Both the first data signal line 9101 and the second data signal line 9102 extend along the second direction Y and are distributed on opposite sides of the first light-transmitting area 4011 along the first direction X.
[0150] The anode connection line 913 is a connection line connecting the second light-emitting transistor 86 and the second reset transistor 87 to the anode 814, and the anode connection line 913 includes a first anode connection line 9131 and a second anode connection line 9132 connected to sub-pixels 101 of different colors; the first anode connection line 9131 and the second anode connection line 9132 are distributed along the first direction X on opposite sides of the first light-transmitting area 4011 and are located at the corner of the first light-transmitting area 4011.
[0151] The reset signal auxiliary line 912 extends along the second direction Y, and is used to connect with other reset signal lines extending along the first direction X to form a mesh structure and reduce impedance. For example, the reset signal auxiliary line 912 can be connected with the second reset signal line 96, or the reset signal auxiliary line 912 can also be connected with other reset signal lines, which is not specifically limited here.
[0152] The reset signal auxiliary line 912 is set adjacent to the first light-transmitting area 4011 at the corner of the first light-transmitting area 4011.
[0153] like Figure 8 As shown, at least some of the functional signal lines 41 include a first connecting segment 411 and a second connecting segment 412 connected to each other, and the first connecting segment 411 is located at the edge of the first light-transmitting area 4011 and bends away from the center of the first light-transmitting area 4011 to avoid the first light-transmitting area 4011.
[0154] The following provides examples of specific lines in functional signal line 41 that can be bent to avoid obstacles.
[0155] In some embodiments, the compensation control signal line 93 may include a first connecting segment 411 and a second connecting segment 412 connected to each other, wherein the first connecting segment 411 is located at the edge of the first light-transmitting area 4011 and bends away from the center of the first light-transmitting area 4011 to avoid the first light-transmitting area 4011.
[0156] In other embodiments, the first reset sub-line 9601 and the first data signal line 9101 may also include a first connecting segment 411 and a second connecting segment 412 connected to each other, and the first connecting segment 411 is located at the edge of the first light-transmitting area 4011 and bends away from the center of the first light-transmitting area 4011 to avoid the first light-transmitting area 4011.
[0157] In some embodiments, the compensation control signal line 93 and the first reset sub-line 9601 both extend along the first direction X and are distributed on opposite sides of the first light-transmitting area 4011 along the second direction Y. At the same time, the compensation control signal line 93 and the first reset sub-line 9601 are both provided with a bent and outwardly extended first connecting segment 411 and a second connecting segment 412 connected to the first connecting segment 411 at the edge of the first light-transmitting area 4011. Therefore, the distance between the first connecting segment 411 of the compensation control signal line 93 and the first connecting segment 411 of the first reset sub-line 9601 along the second direction Y is greater than the distance between the second connecting segment 412 of the compensation control signal line 93 and the second connecting segment 412 of the first reset sub-line 9601 along the second direction Y.
[0158] In this embodiment of the application, the opening 201 can completely cover the first light-transmitting area 4011, thereby maximizing the transmittance at the opening 201 and effectively improving the transmittance of the display panel.
[0159] Furthermore, this application provides comparative examples and embodiments to verify the transmittance of the display panel and the field of view of the sensor provided in this application embodiment.
[0160] In the comparative example, such as Figure 10 and Figure 11 As shown, with Figure 1 and Figure 4 The difference in the illustrated embodiment is that no sub-openings are provided in the first light-shielding sub-layer 23 and the second light-shielding sub-layer 24, that is, no opening 201 is provided in the light-shielding part 20.
[0161] Specifically, the pixel definition layer 13 has a thickness of 1.2 μm, the first sub-pixel 1011 in the first pixel unit 11 can be a green sub-pixel with a length of 11.8 μm along the second direction Y, the second sub-pixel 1012 in the second pixel unit 12 is a red sub-pixel with a length of 13.8 μm along the second direction Y, and the spacing between the first sub-pixel 1011 in the first pixel unit 11 and the second sub-pixel 1012 in the second pixel unit 12 is 18 μm.
[0162] The thickness of the first inorganic encapsulation layer 51 is 1.2 μm, the thickness of the organic encapsulation layer 52 is 8.5 μm, the thickness of the second inorganic encapsulation layer 53 is 0.7 μm, the thickness of the first insulating layer 61 is 0.3 μm, the thickness of the second insulating layer 62 is 0.3 μm, the thickness of the first spacer layer 71 is 5 μm, and the height of the first light-shielding sub-layer 23 is 1.2 μm; the sum of the thicknesses of the second spacer layer 72 and the third spacer layer 73 is 7.5 μm, and the thickness of the second light-shielding sub-layer 24 is 1.2 μm.
[0163] In an embodiment, such as Figure 1 and Figure 4 As shown, this embodiment of the application shows a scheme in which an opening 201 is provided in the light-shielding portion 20. The film layer arrangement outside the first light-shielding sub-layer 23 and the second light-shielding sub-layer 24 is the same as in the comparative example. The first light-shielding sub-layer 23 is arranged as follows: Figure 4 The first sub-opening 2011 is shown, and the second sub-opening 2012 is formed in the second light-shielding sub-layer 24 to form the opening 201. The length of the opening 201 along the second direction Y is 10 μm. A first light-transmitting area 4011 is formed below the opening 201, and ambient light can shine from here onto the sensor below the opening 201.
[0164] Simulations were performed using Lightools software to test the transmittance and FOV of the display panels in the above embodiments and comparative examples, yielding results shown in Table 1 below. Figure 12 The graph shows the transmittance and field of view.
[0165] exist Figure 12 In the diagram, the horizontal axis represents the angle, i.e., the viewing angle; the vertical axis Trans can be regarded as the ratio of light intensity under different viewing angles, i.e., when the light intensity is set to 100% at the frontal angle (0°), the ratio of the light intensity at the preset viewing angle (other angles) to the light intensity at 0° is the Trans of the preset viewing angle; and as the viewing angle increases, the light intensity gradually decreases; while FOV (Field of View) refers to the viewing angle corresponding to Trans being 50%.
[0166] Table 1
[0167] In the comparative example, the product transmittance was 0.25%@550nm and 0.50%@940nm, with FOV: V+: 38.1° and V-: 35.3°; while in the embodiment, the product transmittance was 0.37%@550nm and 0.68%@940nm, with FOV: V+: 34.5° and V-: 31.2°.
[0168] From the data in Table 1 and Figure 12 As can be seen, by providing an opening 201 in the light-shielding part 20 and by specially designing the area and position of the opening 201, the transmittance of the display panel can be effectively improved. At the same time, the field of view of the sensor in the display panel can be kept above 30° without being greatly affected, thus ensuring the light-sensing effect of the sensor.
[0169] In summary, this application embodiment increases the light-transmitting area of the light-shielding portion 20 by forming an opening 201 in the light-shielding portion 20, thereby improving the transmittance of the display panel. Furthermore, the distance between the sub-pixel 101 in the first pixel unit 11 and the edge of the light-shielding portion 20 near the sub-pixel 101 along the first direction X is greater than the distance between the sub-pixel 101 in the second pixel unit 12 and the edge of the light-shielding portion 20 near the sub-pixel 101 along the first direction X. Therefore, the first pixel unit 11 can achieve light emission from a wider viewing angle, while the second pixel unit 12 can achieve light emission from a narrower viewing angle, meaning the second pixel unit 12 can be used for privacy display. In this application, by setting the opening 201 and the second pixel unit 12 to not overlap along the first direction X, the light-shielding effect can be reduced. The opening 201 in part 20 affects the probability of blocking the light emission angle of the second pixel unit 12, reducing the probability of increased light emission from the second pixel unit 12 at the opening 201 in the light-shielding part 20 during privacy display. This allows the display panel to simultaneously achieve high transmittance and good privacy performance. Furthermore, by controlling the area ratio of the opening 201 to the light-transmitting area 401 in this embodiment, the impact on the sensor's field of view can be reduced while ensuring effective improvement in transmittance. In addition, in this embodiment, the opening 201 is aligned with the first light-transmitting area 4011 in the driving circuit layer 40, so that the light passing through the first light-transmitting area 4011 of the driving circuit layer 40 can fully pass through the opening 201, thereby effectively improving the transmittance of the display panel.
