Description

Display panel, manufacturing method thereof, and display device Technical Field

[0001] The present disclosure relates to the field of display technology, and particularly to a display panel, a manufacturing method thereof, and a display device. Background Art

[0002] In actual applications, display products require anti-peeping mode in some private scenarios, but sharing mode in other public ones. This requires the display to be able to switch between anti-peeping and sharing modes at any time. For example, when viewing information on a mobile phone in a public place, when presenting a payment code or entering a password, the phone display can be switched to anti-peeping mode, and to sharing mode in other situations. Furthermore, when using an in-vehicle display, for example, when the passenger is viewing entertainment information, the display can be switched to anti-peeping mode, and to sharing mode in other situations.

[0003] How to optimize the display brightness and viewing angle range in sharing mode and anti-peeping mode is one of the important research topics for researchers in this field.

[0051] It should be noted that, for the sake of clarity, in the drawings used to describe the embodiments of the present invention, the sizes of layers, structures or regions may be enlarged or reduced, that is, these drawings are not drawn according to the actual scale. DETAILED DESCRIPTION

[0052] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0053] It should be noted that in the drawings, the sizes and relative sizes of elements may be exaggerated for clarity and / or descriptive purposes. Thus, the sizes and relative sizes of the individual elements are not necessarily limited to those shown in the drawings. In the specification and drawings, the same or similar reference numerals indicate the same or similar parts.

[0054] Unless otherwise defined, technical or scientific terms used in this disclosure should have the ordinary meanings understood by those of ordinary skill in the art. The terms "first," "second," and similar terms used in this disclosure do not denote any order, quantity, or importance, but are simply used to distinguish different components. The terms "include," "comprising," and similar words mean that the element or object preceding the word encompasses the elements or objects listed after the word, and their equivalents, without excluding other elements or objects.

[0055] Unless otherwise specified, directional terms such as "upper," "lower," "left," "right," "inner," and "outer" are used herein to indicate positions or relationships based on the figures shown. These terms are intended solely to facilitate the description of the present disclosure and are not intended to indicate or imply that the devices, components, or parts referred to must have, be constructed, or operate in a specific orientation. It should be understood that when the absolute positions of the objects being described change, the relative positions they represent may also change accordingly. Therefore, these directional terms should not be construed as limiting the present disclosure.

[0056] It should be noted that, in this article, the term "the same layer" refers to a layer structure formed by using the same film-forming process to form a film layer used to form a specific pattern, and then patterning the film layer using the same mask through a single patterning process. Depending on the specific pattern, a single patterning process may include multiple exposure, development, or etching processes, and the specific pattern in the resulting layer structure may be continuous or discontinuous. In other words, multiple elements, components, structures, and / or parts located in the "same layer" are composed of the same material and are formed through the same patterning process. Typically, multiple elements, components, structures, and / or parts located in the "same layer" have approximately the same thickness.

[0057] Those skilled in the art should understand that, in this article, unless otherwise specified, the expression "height" or "thickness" refers to the dimension of the surface of each film layer arranged perpendicular to the display substrate, that is, the dimension along the light emitting direction of the display substrate, or the dimension along the normal direction of the display device.

[0058] In this document, the directional expressions "first direction" and "second direction" are used to describe different directions along a pixel unit, such as the longitudinal and transverse directions of a pixel unit, or the row and column directions of a sub-pixel arrangement. It should be understood that such expressions are merely exemplary descriptions and are not intended to limit the present disclosure.

[0059] The term "about" in the present disclosure refers to a numerical value that is not strictly defined and allows for process and measurement errors.

[0060] In related technologies, display panels with anti-peeping functions are widely used in various fields. For example, vehicle-mounted display panels usually use AMOLED (Active Matrix Organic Light Emitting Diode) display panels; when the vehicle is in driving state, the display panel needs to switch to the anti-peeping state to reduce visual interference to the user, prevent the display information emitted by the display panel from being obtained by the user in the driving position, and improve the user's driving concentration; when the vehicle is in parking state, the display panel can switch to the sharing state so that the user can obtain the display information emitted by the display panel in time.

[0061] To meet users' anti-peeping needs for display devices, there are a variety of anti-peeping technologies for display panels on the market, such as adding an anti-peeping film on the surface of the display panel. However, this anti-peeping technology cannot change the field of view of the display panel according to user needs and has low flexibility. Some anti-peeping technologies design shared sub-pixels and anti-peeping sub-pixels in the display panel partitions, and switch different display states according to actual needs. That is, when the anti-peeping state is turned on, users outside the light emitting range of the anti-peeping sub-pixels of the display panel cannot obtain the display information. When the display panel is switched to the sharing state, the field of view of the display panel changes, so that users outside the light emitting range of the anti-peeping sub-pixels of the display panel and within the light emitting range of the shared sub-pixels can obtain the display information. However, since the display panel adopts both shared sub-pixels and anti-peeping sub-pixels, the brightness of the output light emitted by the display panel in different display states is relatively low, thereby reducing the overall light efficiency of the display panel, affecting the overall look and feel and visual experience of the display panel.

[0062] Some exemplary embodiments of the present disclosure provide a display panel, comprising: a substrate; a plurality of sub-pixels disposed on the substrate, the plurality of sub-pixels being arranged in an array on the substrate along a first direction and a second direction, the first direction and the second direction intersecting; the plurality of sub-pixels including a plurality of shared sub-pixels and a plurality of anti-peeping sub-pixels, the anti-peeping sub-pixels including anti-peeping pixel openings; a light-shielding layer disposed on the substrate, the light-shielding layer defining a plurality of opening areas, the orthographic projections of the opening areas on the substrate at least partially overlapping with the orthographic projection of at least one of the anti-peeping pixel openings on the substrate; a lens structure disposed on a side of the light-shielding layer away from the substrate, wherein the orthographic projection of at least one of the anti-peeping pixel openings on the substrate falls within the orthographic projection of the lens structure on the substrate, and the orthographic projection of the lens structure on the substrate at least partially overlaps with the orthographic projection of at least one of the opening areas on the substrate.

[0063] By partitioning the anti-peeping sub-pixels and shared sub-pixels and setting a light-shielding layer and lens structure in the area where the anti-peeping sub-pixels are located, the viewing angle range in the anti-peeping mode can be effectively reduced and the display brightness in the anti-peeping mode can be improved, achieving a better display effect.

[0064] FIG. 1 is a schematic diagram illustrating a partial pixel arrangement of a display panel according to some embodiments of the present disclosure.

[0065] 1 , in some embodiments, a display panel 100 includes a base substrate 1 and a plurality of sub-pixels disposed on the base substrate 1. The plurality of sub-pixels include a plurality of shared sub-pixels px and a plurality of privacy-preventing sub-pixels px'. The plurality of sub-pixels are arranged in an array along a first direction X and a second direction Y on the base substrate 1, where the first direction X and the second direction Y intersect.

[0066] For example, the display panel 100 may include a plurality of shared pixel unit rows PR1 and a plurality of privacy protection pixel unit rows PR2 .

[0067] Exemplarily, the shared pixel unit row PR1 may include a plurality of shared pixel units PX, and the privacy protection pixel unit row PR2 may include a plurality of privacy protection pixel units PX′.

[0068] For example, the plurality of shared pixel units PX may include a plurality of shared sub-pixels px, and the plurality of privacy protection pixel units PX′ may include a plurality of privacy protection sub-pixels px′.

[0069] Exemplarily, the shared pixel unit rows PR1 and the privacy protection pixel unit rows PR2 are arranged alternately.

[0070] In some embodiments, each shared pixel unit row in the plurality of shared pixel unit rows PR1 includes a plurality of shared sub-pixels px arranged in sequence. Each anti-peeping pixel unit row in the plurality of anti-peeping pixel unit rows PR2 includes a plurality of anti-peeping sub-pixels px' arranged in sequence. Each sub-pixel can be separated by a pixel definition layer PDL, which forms a plurality of openings, namely pixel openings 30. The light-emitting layer of the sub-pixel is located in the pixel openings 30, thereby defining the corresponding light-emitting shape and area. For example, the shared sub-pixel px includes a shared pixel opening 31, and the anti-peeping sub-pixel px' includes an anti-peeping pixel opening 32.

[0071] FIG. 2 illustrates a structure of a portion of a display panel according to some embodiments of the present disclosure.

[0072] For example, referring to FIG. 1 and FIG. 2 , in some embodiments, each shared pixel unit PX in the plurality of shared pixel units PX includes a first sub-pixel sp1 , a second sub-pixel sp2 , and a third sub-pixel sp3 .

[0073] In some embodiments, each of the plurality of privacy protection pixel units PX' includes one or more fourth sub-pixels sp1', one or more fifth sub-pixels sp2', and one or more sixth sub-pixels sp3'. In one example depicted in Figures 1 and 2, each privacy protection pixel unit PX' includes a plurality of fourth sub-pixels sp1' (e.g., 10 fourth sub-pixels sp1'), a plurality of fifth sub-pixels (e.g., 4 fifth sub-pixels sp2'), and a plurality of sixth sub-pixels (e.g., 8 sixth sub-pixels sp3').

[0075] In some examples, at least some of the privacy protection pixel units PX′ include a plurality of fourth sub-pixels, a plurality of fifth sub-pixels, and a single sixth sub-pixel.

[0076] In some examples, at least some of the privacy protection pixel units PX′ include a single fourth sub-pixel, a plurality of fifth sub-pixels, and a plurality of sixth sub-pixels.

[0077] In some examples, at least some of the privacy protection pixel units PX′ include a plurality of fourth sub-pixels, a single fifth sub-pixel, and a plurality of sixth sub-pixels.

[0078] In some embodiments, the first sub-pixel sp1 and the plurality of fourth sub-pixels sp1' are sub-pixels of a first color (e.g., green). In some embodiments, the second sub-pixel sp2 and the plurality of fifth sub-pixels sp2' are sub-pixels of a second color (e.g., red). In some embodiments, the third sub-pixel sp3 and the plurality of sixth sub-pixels are sub-pixels of a third color (e.g., blue). By setting the adjacent shared sub-pixels px and the anti-peeping sub-pixels px' to the same color, even if the light-emitting layer colors of the adjacent shared sub-pixels px and the anti-peeping sub-pixels px' are the same, the interference and mixing between the shared sub-pixels px and the anti-peeping sub-pixels px' can be reduced, thereby preventing the display panel from having color cast or uneven brightness during the display process.

[0079] In some embodiments, the anode included in the anti-peeping sub-pixel and the anode included in the shared sub-pixel can be independent of each other. The light-emitting layer included in the anti-peeping sub-pixel and the light-emitting layer included in the shared sub-pixel can be shared, that is, the two can form an integrated structure. The anti-peeping sub-pixel and the shared sub-pixel can share the same cathode layer.

[0080] In some embodiments, the display panel includes an integral anode configured to provide a power signal to a plurality of fourth sub-pixels sp1' in each privacy protection pixel unit PX'. In some embodiments, the display panel includes an integral anode configured to provide a power signal to a plurality of fifth sub-pixels sp2' in each privacy protection pixel unit PX'. In some embodiments, the display panel includes an integral anode configured to provide a power signal to a plurality of sixth sub-pixels sp3' in each privacy protection pixel unit PX'.

[0081] In some examples, the display panel includes a plurality of anodes configured to independently provide power signals to the plurality of fourth sub-pixels sp1 ′ in each privacy protection pixel unit PX′.

[0082] In some examples, the display panel includes a plurality of anodes configured to independently provide power signals to the plurality of fifth sub-pixels sp2 ′ in each anti-peeping pixel unit PX′.

[0083] In some examples, the display panel includes a plurality of anodes configured to independently provide power signals to the plurality of sixth sub-pixels sp3 ′ in each privacy protection pixel unit PX′.

[0084] In some embodiments, the display panel includes an integral cathode for the plurality of fourth sub-pixels sp1' in each anti-peeping pixel unit PX' and the first sub-pixel sp1 in the shared pixel unit PX in the first adjacent shared pixel unit row PR1-1. In some embodiments, the display panel includes an integral light-emitting layer for the plurality of fourth sub-pixels sp1' in each anti-peeping pixel unit PX' and the first sub-pixel sp1 in the shared pixel unit PX in the first adjacent shared pixel unit row PR1-1. In some embodiments, the display panel includes two independent anodes, one for the plurality of fourth sub-pixels sp1' in each anti-peeping pixel unit PX' and one for the first sub-pixel sp1 in the shared pixel unit PX in the first adjacent shared pixel unit row PR1-1. The two independent anodes are independently controlled and configured to receive independent power signals.

[0085] In some embodiments, the display panel includes an integral cathode for the plurality of fifth sub-pixels sp2' in each privacy-preventing pixel unit PX' and the second sub-pixel sp2 in the shared pixel unit PX in the second adjacent shared pixel unit row PR1-2. Each privacy-preventing sub-pixel is located in the privacy-preventing pixel unit row PR2 that separates the first adjacent shared pixel unit row PR1-1 and the second adjacent shared pixel unit row PR1-2. In some embodiments, the display panel includes an integral light-emitting layer for the plurality of fifth sub-pixels sp2' in each privacy-preventing pixel unit PX' and the second sub-pixel sp2 in the shared pixel unit PX in the second adjacent shared pixel unit row PR1-2. In some embodiments, the display panel includes two independent anodes, one for the plurality of fifth sub-pixels sp2' in each privacy-preventing pixel unit PX' and one for the second sub-pixel sp2 in the shared pixel unit PX in the second adjacent shared pixel unit row PR1-2. The two independent anodes are independently controlled and configured to receive independent power signals.

[0086] In some embodiments, the display panel includes an integral cathode for the plurality of sixth sub-pixels sp3' in each privacy protection pixel unit PX' and the third sub-pixel sp3 in the shared pixel unit PX in the second adjacent shared pixel unit row PR1-2. In some embodiments, the display panel includes an integral light-emitting layer for the plurality of sixth sub-pixels sp3' in each privacy protection pixel unit PX' and the third sub-pixel sp3 in the shared pixel unit PX in the second adjacent shared pixel unit row PR1-2. In some embodiments, the display panel includes two independent anodes, one for the plurality of sixth sub-pixels sp3' in each privacy protection pixel unit PX' and one for the third sub-pixel sp3 in the shared pixel unit PX in the second adjacent shared pixel unit row PR1-2. The two independent anodes are independently controlled and configured to receive independent power signals.

[0087] In some embodiments, the display panel is configured to operate in a first mode, a second mode, or a third mode. In the first mode, the shared sub-pixels in the plurality of shared pixel unit rows PR1 and the anti-peeping sub-pixels in the plurality of anti-peeping pixel unit rows PR2 are configured to emit light. In the second mode, the anti-peeping sub-pixels in the plurality of anti-peeping pixel unit rows PR2 are configured to display an image (e.g., emit light), while the shared sub-pixels in the plurality of shared pixel unit rows PR1 are not configured to display an image (e.g., not emit light). In some embodiments, the second mode is an anti-peeping mode (privacy mode). In the third mode, the anti-peeping sub-pixels in the plurality of anti-peeping pixel unit rows PR2 are not configured to display an image (e.g., emit light), while the shared sub-pixels in the plurality of shared pixel unit rows PR1 are configured to display an image (e.g., emit light).

[0088] It should be noted that in the above-described embodiments, the number of shared sub-pixels px and the number of anti-peeping sub-pixels px', as well as the specifications such as the opening area of ​​a single shared sub-pixel px and the opening area of ​​a single anti-peeping sub-pixel px', can be selected and arranged according to the display panel manufacturing process. For example, the number of shared sub-pixels px and the number of anti-peeping sub-pixels px' can be set to be the same or different, and / or the opening area of ​​a single shared sub-pixel px and the opening area of ​​a single anti-peeping sub-pixel px' can be set to be the same or different, so that the display panel presents different display effects in the shared state and the anti-peeping state. For example, for the shared sub-pixels px and the anti-peeping sub-pixels px' in the display panel, the number of shared sub-pixels px can be less than the number of anti-peeping sub-pixels px', and the opening area of ​​a single shared sub-pixel px can be different from the opening area of ​​a single anti-peeping sub-pixel px'.

[0089] In some embodiments, each shared pixel unit PX in the plurality of shared pixel unit rows PR1 includes a first sub-pixel sp1, a second sub-pixel sp2, and a third sub-pixel sp3. Each privacy protection pixel unit PX' in the plurality of privacy protection pixel unit rows PR2 includes a plurality of fourth sub-pixels sp1', a plurality of fifth sub-pixels sp2', and a plurality of sixth sub-pixels sp3'. The total number of the plurality of fourth sub-pixels sp1' is 2, the total number of the plurality of fifth sub-pixels sp2' is 2, and the total number of the plurality of sixth sub-pixels sp3' is 2.

[0090] In some examples, the number of the plurality of sixth sub-pixels sp3' included in each privacy protection pixel unit PX' in the plurality of privacy protection pixel unit rows PR2 is greater than or equal to the number of the fifth sub-pixels sp2', and is greater than the number of the fourth sub-pixels sp1'. The number of the first sub-pixels sp1, the second sub-pixels sp2, and the third sub-pixels sp3 included in each shared pixel unit PX in the plurality of shared pixel unit rows PR1 is equal.

[0091] In some examples, the total number of the plurality of fourth sub-pixels sp1 ′ is 2, the total number of the plurality of fifth sub-pixels sp2 ′ is 4, and the total number of the plurality of sixth sub-pixels sp3 ′ is 4.

[0092] In some examples, the total number of the plurality of fourth sub-pixels sp1 ′ is 3, the total number of the plurality of fifth sub-pixels sp2 ′ is 6, and the total number of the plurality of sixth sub-pixels sp3 ′ is 9.

[0093] In some examples, the total number of the plurality of fourth sub-pixels sp1 ′ is 3, the total number of the plurality of fifth sub-pixels sp2 ′ is 9, and the total number of the plurality of sixth sub-pixels sp3 ′ is 9.

[0094] Generally, the larger the area allocated to sub-pixels of the same color in the same sub-pixel, the greater the number of sub-pixels of the same color in the same sub-pixel. In some embodiments, the ratio of the number of the plurality of fourth sub-pixels sp1', the number of the plurality of fifth sub-pixels sp2', and the number of the plurality of sixth sub-pixels sp3' is in the range of 1 to 3, for example, 1, 2, or 3.

[0095] In some embodiments, for privacy protection sub-pixels of the same color, the shapes and sizes of the privacy protection sub-pixels may be the same or different, for example, the same.

[0096] For example, for privacy protection sub-pixels of different colors, the shapes and sizes of the privacy protection sub-pixels can be the same or different. For example, the area ratio of a single fourth sub-pixel sp1' to a single fifth sub-pixel sp2' is in a range of 0.5 to 2.0. For example, the area ratio of a single fourth sub-pixel sp1' to a single sixth sub-pixel sp3' is in a range of 0.5 to 2.0. For example, the area ratio of a single fifth sub-pixel sp2' to a single sixth sub-pixel sp3' is in a range of 0.5 to 2.0.

[0097] In some embodiments, in an anti-peeping pixel unit, the total area A1 of the anti-peeping pixel openings of multiple anti-peeping sub-pixels of the same color is less than or equal to the total area A2 of the pixel openings of the shared sub-pixels of the same color in a corresponding shared pixel unit. Exemplarily, A1 / A2 is greater than or equal to 0.5 and less than or equal to 1. For example, A1 / A2 is equal to 4 / 6, or A1 / A2 is equal to 4 / 7. In some embodiments, the first sub-pixel sp1 and the fourth sub-pixel sp1' are sub-pixels that display green, the second sub-pixel sp2 and the fifth sub-pixel sp2' are sub-pixels that display red, and the third sub-pixel sp3 and the sixth sub-pixel sp3' are sub-pixels that display blue. As shown in Figure 2 , for a shared sub-pixel px within the same pixel region, the opening area of ​​a single red second sub-pixel sp2 can be smaller than the opening area of ​​a single blue third sub-pixel sp3; the opening area of ​​a single blue third sub-pixel sp3 can be smaller than the opening area of ​​a single green first sub-pixel sp1. For privacy-preventing sub-pixels px' within the same pixel region, the total opening area of ​​the red fifth sub-pixels sp2' can be smaller than the total opening area of ​​the blue sixth sub-pixels sp3'; and the total opening area of ​​the blue sixth sub-pixels sp3' can be smaller than the total opening area of ​​the green fourth sub-pixels sp1'. The total opening area is equal to the product of the opening area of ​​a single privacy-preventing sub-pixel and the number of corresponding privacy-preventing sub-pixels within the same pixel region. For example, in the same pixel region of Figure 2 , the number of red fifth sub-pixels sp2' is four, and the total opening area of ​​the red fifth sub-pixels sp2' is four times the opening area of ​​a single red fifth sub-pixel sp2'.

[0098] In some embodiments, the opening shape of the shared sub-pixel px is set to be strip-shaped, and the extension direction of adjacent shared sub-pixels px is the same; the opening shape of the anti-peeping sub-pixel px' is set to be dot-shaped, but not limited thereto.

[0099] By setting the shared sub-pixel px to a strip shape and making the shared sub-pixels px in each pixel area extend in the same direction, the field of view of the shared sub-pixel px in the extension direction can be expanded, and the field of view in the direction perpendicular to the extension direction of the shared sub-pixel px can be limited, so that the display panel can share display information in a direction and avoid information leakage in other directions; and setting the anti-peeping sub-pixel px' to a dot shape can make the field of view of the display panel remain unchanged in different display states, ensuring that the light output effect between each pixel area is relatively uniform, so that users located in the light output range of the anti-peeping sub-pixel px' can obtain clearer and more stable display information.

[0100] 2 , in a combination including a single anti-peeping pixel unit and a single shared pixel unit, the projections of multiple anti-peeping sub-pixels of the same color on the substrate have a maximum coverage width m1 in the first direction X, and the projections of shared sub-pixels corresponding to the multiple anti-peeping sub-pixels on the substrate have a maximum coverage width m2 in the first direction X, where m2 is less than or equal to m1.

[0101] 2 , in some embodiments, in a combination including a single privacy protection pixel unit and a single shared pixel unit, the minimum spacing distance between the second sub-pixel sp2 and the third sub-pixel sp3 is n2. The minimum spacing distance between the plurality of fifth sub-pixels sp2' and the plurality of sixth sub-pixels sp3' is n1, where n2 is greater than or equal to n1.

[0102] It should be noted that in some embodiments of the present disclosure, both shared sub-pixels and privacy-preventing sub-pixels may employ an S-stripe RGB pixel arrangement, but the arrangement is not limited thereto. For example, shared sub-pixels and privacy-preventing sub-pixels may also employ various known pixel arrangements in the art, such as a Delta RGB pixel arrangement, a GGRB pixel arrangement, a Blue Diamond pixel arrangement, and a Diamond pixel arrangement.

[0103] Figure 3 shows a schematic partial cross-sectional view of the display panel according to some embodiments of the present disclosure, taken along the center line AA' of Figure 2; Figure 4 shows a comparative diagram of the light emission effects of the display panel with / without the lens structure in Figure 3; Figure 5 shows a schematic partial cross-sectional view of the display panel according to other embodiments of the present disclosure, taken along the center line AA' of Figure 2; Figure 6 shows a comparative diagram of the light emission effects of the display panel with / without the lens structure in Figure 5; Figure 7 shows a schematic partial cross-sectional view of the display panel according to other embodiments of the present disclosure, taken along the center line AA' of Figure 2; Figure 8 shows a comparative diagram of the light emission effects of the display panel with / without the lens structure in Figure 7; Figure 9 shows a schematic partial cross-sectional view of the display panel according to other embodiments of the present disclosure, taken along the center line AA' of Figure 2; Figure 10 shows a comparative diagram of the light emission effects of the display panel with / without the lens structure in Figure 9.

[0104] For example, in some embodiments of the present disclosure, with reference to FIG3 , FIG5 , FIG7 and FIG9 , the display panel includes: a base substrate 1 and a pixel defining layer PDL. The pixel defining layer PDL located in the area where the anti-peep sub-pixels are located defines a plurality of anti-peep pixel openings 32. The display panel may further include a light shielding layer 20 disposed on the base substrate 1. For example, the light shielding layer 20 may include at least one of a first sub-light shielding layer 201, a second sub-light shielding layer 202 or a third sub-light shielding layer 203. The light shielding layer defines a plurality of opening areas 210. For example, the opening area 210 may include at least one of a first opening area 211, a second opening area 212 or a third opening area 213.

[0105] The orthographic projection of the opening area 210 on the base substrate 1 at least partially overlaps with the orthographic projection of at least one privacy-preventing pixel opening 32 on the base substrate. By providing a light-shielding layer, at least a majority of light emitted by the privacy-preventing sub-pixel can only be emitted from the opening area 210 toward the light-emitting side of the display panel, thereby enabling the display panel to achieve privacy-preventing mode through the privacy-preventing sub-pixel.

[0106] For example, the display panel may further include a pixel driver circuit layer (not shown) disposed between the pixel defining layer (PDL) and the base substrate 1 to drive each sub-pixel to emit light. The pixel driver circuit layer may employ various pixel driver designs known in the art, such as 3T1C, 7T1C, 7T2C, and 8T2C, which will not be described in detail here.

[0107] The display panel also includes a lens structure 7 disposed on the side of the light shielding layer 20 away from the base substrate 1. The orthographic projection of at least one privacy-prevention pixel opening 32 on the base substrate 1 falls within the orthographic projection of the lens structure 7 on the base substrate 1. The orthographic projection of the lens structure 7 on the base substrate at least partially overlaps with the orthographic projection of at least one opening area 210 on the base substrate 1. By disposing the lens structure 7 above the privacy-prevention pixel opening, the light extraction efficiency of the privacy-prevention sub-pixel can be further improved, further enhancing the display quality of the display panel in privacy-prevention mode.

[0108] The display panel may further include an encapsulation layer 3, which is disposed on a side of the pixel definition layer (PDL) away from the base substrate. The encapsulation layer 3 is used to encapsulate multiple sub-pixels of the display substrate, such as multiple shared sub-pixels and multiple anti-peep sub-pixels. In other words, in some embodiments of the present disclosure, the shared sub-pixels and the anti-peep sub-pixels may share the same encapsulation layer.

[0109] The display panel may further include a touch layer 5 disposed on a side of the encapsulation layer 3 away from the base substrate 1, wherein at least one touch electrode is located in the touch layer. By designing the touch layer, the display panel can achieve touch control.

[0110] For example, a second protective layer 4 may be provided between the encapsulation layer 3 and the touch layer 5. The second protective layer 4 may be an insulating layer.

[0111] For example, in some embodiments of the present disclosure, referring to FIG5 , the first sub-light-shielding layer 201 is located between the touch layer 5 and the lens structure 7. For example, referring to FIG9 , the second sub-light-shielding layer 202 is located between the touch layer 5 and the encapsulation layer 3. For example, referring to FIG7 , at least a portion of the touch layer 5 is reused as the third sub-light-shielding layer 203.

[0112] The first sub-light-shielding layer 201, the second sub-light-shielding layer 202, and the third sub-light-shielding layer 203 can be used individually as light-shielding layers, or they can be designed in combination to achieve a better anti-peeping display effect. For example, the first sub-light-shielding layer 201 and the second sub-light-shielding layer 202 can be designed in combination. Alternatively, the second sub-light-shielding layer 202 and the third sub-light-shielding layer 203 can be designed in combination. Alternatively, the first sub-light-shielding layer 201 and the third sub-light-shielding layer 203 can be designed in combination. Alternatively, the first sub-light-shielding layer 201, the second sub-light-shielding layer 202, and the third sub-light-shielding layer 203 can be designed in combination.

[0113] For example, in some embodiments of the present disclosure, referring to FIG3 , the maximum width of the orthographic projection of the anti-peeping pixel opening 32 on the substrate along the first direction X is a first width d1, and the maximum width of the orthographic projection of the lens structure 7 on the substrate along the first direction X is a second width d2, and the ratio of the first width d1 to the second width d2 is less than or equal to 0.6. For example, the first width d1 is less than or equal to 6 microns, and the second width d2 is between 6 microns and 40 microns, which may include endpoint values, but is not limited to this. For example, the first width d1 is 6 microns and the second width d2 is 11 microns. By designing a small-sized light-emitting area and a relatively large-sized lens structure in the anti-peeping sub-pixel area, the viewing angle of the anti-peeping area can be reduced, which is beneficial to improving the anti-peeping effect. At the same time, the display brightness of the anti-peeping area can be increased, which is beneficial to improving the overall display effect of the display panel.

[0114] Exemplarily, with reference to Figures 2 and 3, in some embodiments of the present disclosure, the spacing distance between adjacent anti-peeping pixel openings is d7, and the spacing distance d7 between different anti-peeping pixel openings may be the same or different. For example, for anti-peeping sub-pixels that emit light of the same color, the spacing distance between the anti-peeping pixel openings is d72. For example, with reference to Figure 3, the spacing distance between the two anti-peeping pixel openings corresponding to the two sixth sub-pixels sp3' is d72. For two adjacent anti-peeping sub-pixels that emit light of different colors, the spacing distance between the anti-peeping pixel openings is d71. For example, the spacing distance between the anti-peeping pixel opening corresponding to a fourth sub-pixel sp1' and the anti-peeping pixel opening corresponding to an adjacent sixth sub-pixel sp3' is d71. Exemplarily, d72 is less than d71.

[0115] For example, in some embodiments of the present disclosure, referring to FIG. 3 , the light-emitting layer EL of the privacy protection sub-pixel includes a first surface EL1 distal from the base substrate, and the lens structure 7 includes a second surface 71 proximal to the base substrate. A first spacing distance H1 separates the first surface EL1 from the second surface 71. The first spacing distance H1 is less than the sum of the first width d1 and the second width d2. For example, the first spacing distance H1 is 14 microns, the first width is 6 microns, and the second width is 11 microns.

[0116] For example, in some embodiments of the present disclosure, referring to FIG3 , the pixel definition layer (PDL) can be made of a black material. The encapsulation layer 3 can be a thin film encapsulation layer, such as a three-layer or multi-layer structure of inorganic / organic / inorganic. For example, the encapsulation layer has a fourth thickness h4, which is between 2 microns and 20 microns, for example, between 8 microns and 20 microns, including but not limited to these values. The touch layer can be composed of one or more layers of metal mesh. The touch layer includes multiple metal traces. For example, referring to FIG3 , the touch layer 5 includes multiple touch sub-lines 51 located between multiple privacy protection sub-pixels. At least a portion of the multiple touch sub-lines 51 is used to provide touch signals to the corresponding privacy protection sub-pixels. The orthographic projection of at least a portion of the touch sub-lines 51 on the substrate along the first direction has a third width d3, which is less than the first width d1. For example, the third width d3 is between 2 microns and 4 microns, while the first width d1 is 6 microns, including but not limited to these values. In some embodiments, the widths of the plurality of touch sub-lines 51 in the touch layer 5 may be set to be relatively small, and are only used to transmit touch signals.

[0117] At least a portion of the multiple metal traces undergoes a blackening treatment near the bottom surface of the substrate. Exemplarily, the blackened metal traces have a low light reflectivity of approximately 5%, thereby reducing stray light. A first protective layer 6 may also be disposed above the touch layer 5. The thickness of the first protective layer 6 is between 2 and 5 microns, inclusive, but not limited to these values. The lens structure 7 may be a hemispherical or spherical cap structure. The second width d2 of the lens structure is between 8 and 40 microns, inclusive, but not limited to these values. The lens structure is formed of a high-refractive-index material. For example, the refractive index of the material in the lens structure 7 is between 1.5 and 1.8, inclusive, but not limited to these values. The material surrounding the lens structure 7 is a low-refractive-index material. For example, in Figure 3, the first protective layer 6 below the lens structure 7 is formed of a low-refractive-index material. The refractive index of the material in the lens structure 7 is greater than the refractive index of the material in the first protective layer 6. For example, the refractive index of the material in the first protective layer 6 is between 1.4 and 1.6, inclusive, but not limited to these values.

[0118] The display panel may further include a fourth cover layer 8 located on a side of the lens structure 7 away from the base substrate. The refractive index of the material in the fourth cover layer 8 is lower than the refractive index of the material in the lens structure 7. For example, the refractive index of the material in the fourth cover layer 8 is between 1.4 and 1.6, including but not limited to these values.

[0119] By designing the refractive index of the lens structure material to be higher than the refractive index of the surrounding materials, the focusing effect of the lens structure can be improved, which is conducive to further improving the display brightness of the display panel in the anti-peep mode.

[0120] Exemplarily, the display panel may further include an optical adhesive layer 9 , a cover plate 10 and a hardened protective layer 11 located on the fourth cover layer 8 .

[0121] For example, referring to Figure 4, the horizontal axis represents the different viewing angles of the anti-peeping pixel area, and the vertical axis represents the relative light intensity of the two display panels (other structures are the same) with and without the lens structure at different viewing angles. By comparison, it can be seen that after the display panel of the embodiment shown in Figure 3 is provided with the lens structure, the brightness of the anti-peeping pixel area in the positive viewing angle range (for example, -20° to 20°, or -30° to 30°) is greatly improved, and the brightness near the 0° viewing angle is increased by about 300%, which is conducive to further improving the display effect of the display panel in anti-peeping mode.

[0122] For example, in some embodiments of the present disclosure, referring to FIG. 5 , the pixel definition layer (PDL) can be made of a black material. The encapsulation layer 3 can be a thin film encapsulation layer, such as a three-layer or multi-layer structure of inorganic / organic / inorganic. For example, the encapsulation layer has a fourth thickness h4, which is between 2 microns and 20 microns, for example, between 8 microns and 20 microns, including but not limited to end values. The touch layer can be composed of one or more layers of metal mesh. The touch layer 5 includes multiple metal traces. For example, the touch layer 5 includes multiple touch sub-lines 51 located between multiple anti-peep sub-pixels. The orthographic projection of at least a portion of the touch sub-lines 51 on the substrate has a third width d3 along the first direction, which is between 2 microns and 4 microns. At least a portion of the multiple metal traces is blackened near the lower surface of the substrate. For example, the blackened metal traces have a low light reflectivity of approximately 5%, thereby reducing stray light. A first protective layer 6 can also be provided above the touch layer 5. The thickness of the first protective layer 6 is between 2 microns and 5 microns, including endpoint values, but not limited thereto. The lens structure 7 can be a hemispherical or spherical crown structure. The second width d2 of the lens structure 7 is between 8 microns and 40 microns, including endpoint values, but not limited thereto. The lens structure 7 is formed of a high refractive index material. For example, the refractive index of the material in the lens structure 7 is between 1.5 and 1.8, including endpoint values, but not limited thereto. The material around the lens structure 7 is a low refractive index material. The display panel can also include a fourth covering layer 8, an optical adhesive layer 9, a cover plate 10 and a hardened protective layer 11 located above the lens structure 7. No further details will be given here.

[0123] 5 , the light shielding layer may further include a first sub-light shielding layer 201 located between the touch layer 5 and the lens structure 7 .

[0124] For example, referring to FIG. 17 , the lens structure 7 and the first light-shielding sub-layer 201 may be in direct contact at least partially.

[0125] For example, referring to FIG5 , a first cover layer 12 may be further provided between the first sub-light-shielding layer 201 and the lens structure 7. For example, the first cover layer may be an insulating layer. The first cover layer 12 may cover the upper surface of the first sub-light-shielding layer 201, thereby spacing the lens structure 7 closer to the substrate and the first sub-light-shielding layer 201 further from the substrate. "Separated" means that the lens structure 7 is not in direct contact with the first sub-light-shielding layer 201.

[0126] The first sub-light-shielding layer 201 includes a plurality of first sub-light-shielding portions 2011. The orthographic projection of at least one first sub-light-shielding portion 2011 on the substrate has a fifth width d5 ​​along the first direction. The fifth width d5 ​​is between 4 micrometers and 20 micrometers, including but not limited to the end values.

[0127] Exemplarily, the first sub-light-shielding layer 201 defines a plurality of first opening areas 211. The orthographic projection of the boundary of the anti-peeping pixel opening 32 on the substrate is surrounded by the orthographic projection of the boundary of the corresponding first opening area 211 on the substrate. Alternatively, the orthographic projection of the anti-peeping pixel opening 32 on the substrate at least partially overlaps with the orthographic projection of the first sub-light-shielding layer 201 on the substrate. For example, the distance between the orthographic projection of the boundary of the anti-peeping pixel opening 32 on the substrate and the orthographic projection of the boundary of the corresponding first opening area 211 on the substrate is between -3 microns and 10 microns, and can also be set between -1 micron and 10 microns, for example, between 0 and 6 microns, and the above ranges may include endpoint values.

[0128] It should be noted that when the above distance is a positive value, it means that the orthographic projection of the boundary of the anti-privacy pixel opening 32 on the base substrate does not overlap with the orthographic projection of the first sub-light-shielding layer 201 on the base substrate. When the above distance is a negative value, it means that the orthographic projection of the boundary of the anti-privacy pixel opening 32 on the base substrate overlaps with the orthographic projection of the first sub-light-shielding layer 201 on the base substrate.

[0129] By providing the first sub-light shielding layer 201, at least most of the light emitted by the anti-peeping sub-pixel can only be emitted from the first opening area 211 to the light-emitting side of the display panel, so that the display panel can achieve an anti-peeping mode through the anti-peeping sub-pixel.

[0130] For example, in some embodiments of the present disclosure, the first sub-light-shielding layer 201 has a first thickness h1, and the encapsulation layer 3 has a fourth thickness h4. The ratio of the first thickness h1 to the fourth thickness h4 is greater than or equal to 0.05 and less than or equal to 0.5. For example, the first thickness h1 is between 1 micron and 3 microns, and the fourth thickness h4 is between 2 microns and 20 microns, for example, 8 microns to 20 microns. The above ranges may include endpoints.

[0131] For example, referring to Figure 6, the horizontal axis represents the different viewing angles of the anti-peeping pixel area, and the vertical axis represents the relative light intensity of the two display panels (other structures are the same) with and without the lens structure at different viewing angles. By comparison, it can be seen that after the display panel of the embodiment shown in Figure 5 is provided with the lens structure, the brightness of the anti-peeping pixel area in the positive viewing angle range (for example, -20° to 20°, or -30° to 30°) is greatly improved, and the brightness near the 0° viewing angle is increased by about 300%, which is conducive to further improving the display effect of the display panel in anti-peeping mode.

[0132] For example, in some embodiments of the present disclosure, referring to FIG7 , the pixel defining layer PDL may be made of a black material. The encapsulation layer 3 may be a thin film encapsulation, such as a three-layer or multi-layer structure of inorganic / organic / inorganic. For example, the encapsulation layer 3 has a fourth thickness h4, and the fourth thickness h4 is between 2 microns and 20 microns, such as 8 microns to 20 microns, and may include end point values, but is not limited thereto. The touch layer 5 may be composed of one or more layers of metal grids. The touch layer 5 includes a plurality of metal traces, and at least a portion of the plurality of metal traces is blackened near the lower surface of the substrate, thereby reducing stray light. Among them, at least a portion of the plurality of metal traces is reused as a third sub-light-shielding layer 203. The third sub-light-shielding layer 203 defines a plurality of third opening areas 213, wherein the orthographic projection of the third opening area 213 on the substrate at least partially overlaps with the orthographic projection of the corresponding lens structure 7 on the substrate.

[0133] 7 , the third sub-light-shielding layer 203 may include a plurality of third sub-light-shielding portions 2031. The orthographic projections of the third sub-light-shielding portions 2031 on the base substrate define corresponding third opening areas 213. The orthographic projections of the third sub-light-shielding portions 2031 on the base substrate at least partially overlap with the orthographic projections of the lens structure 7 on the base substrate.

[0134] Exemplarily, the orthographic projection of the boundary of the privacy pixel opening 32 on the substrate is surrounded by the orthographic projection of the boundary of the corresponding third opening area 213 on the substrate. Alternatively, the orthographic projection of the privacy pixel opening 32 on the substrate at least partially overlaps with the orthographic projection of the third sub-light-shielding layer 203 on the substrate. For example, the distance between the orthographic projection of the boundary of the privacy pixel opening 32 on the substrate and the orthographic projection of the boundary of the corresponding third opening area 213 on the substrate is between -3 microns and 10 microns, and can also be set between -1 micron and 10 microns, for example, between 0 and 6 microns, and the above ranges may include endpoint values.

[0135] It should be noted that when the above distance is a positive value, it means that the orthographic projection of the boundary of the anti-privacy pixel opening 32 on the base substrate does not overlap with the orthographic projection of the third sub-light-shielding layer 203 on the base substrate. When the above distance is a negative value, it means that the orthographic projection of the boundary of the anti-privacy pixel opening 32 on the base substrate overlaps with the orthographic projection of the third sub-light-shielding layer 203 on the base substrate.

[0136] A first protective layer 6 can also be provided above the touch layer 5. The thickness of the first protective layer 6 is between 2 microns and 5 microns, including endpoint values, but not limited thereto. The lens structure 7 can be a hemispherical or spherical crown structure. The second width d2 of the lens structure 7 is between 8 microns and 40 microns, including endpoint values, but not limited thereto. The lens structure is formed of a high refractive index material. For example, the refractive index of the material in the lens structure 7 is between 1.5 and 1.8, including endpoint values, but not limited thereto. The material around the lens structure 7 is a low refractive index material. Exemplarily, the display panel can also include a fourth covering layer 8, an optical adhesive layer 9, a cover plate 10 and a hardened protective layer 11 located above the lens structure 7. No further details will be given here.

[0137] 7 , an orthographic projection of at least a portion of the third light-shielding portion 2031 on the substrate has a fourth width d4 along the first direction X. The ratio of the fourth width d4 to the second width d2 is between 0.2 and 0.8, for example, approximately 0.5. For example, the fourth width d4 is between 4 micrometers and 20 micrometers, including but not limited to these values.

[0138] By reusing at least a portion of the touch layer as the third sub-light-shielding layer 203, the formation of a third sub-light-shielding layer 203 specifically used for light shielding in the touch display panel is avoided, the number of film layers inside the touch display panel is reduced, and the internal structure of the touch display panel is optimized, thereby solving the problems of complex structure, large product thickness, and high production cost when the display product realizes the switching function between the anti-peep mode and the shared screen information mode.

[0139] Exemplarily, the first protective layer 6 may be used as a third covering layer, so that the lens structure 7 is spaced apart from the surface of the substrate close to the base substrate and the surface of the third sub-light-shielding layer 203 is spaced apart from the base substrate.

[0140] Exemplarily, the refractive index of the material in the third covering layer is smaller than the refractive index of the material in the lens structure, thereby achieving a better light focusing effect of the lens structure.

[0141] For example, in some embodiments of the present disclosure, the third sub-light-shielding layer 203 has a third thickness h3. The ratio of the third thickness h3 to the fourth thickness h4 is greater than or equal to 0.005 and less than or equal to 0.5. For example, the third thickness h3 is between 0.1 microns and 3 microns, and the fourth thickness h4 is between 2 microns and 20 microns, for example, 8 microns to 20 microns. These ranges may include endpoints. By making the third sub-light-shielding layer 203 thinner, the flatness of the film layer can be increased, which facilitates the formation of the lens structure above the light-shielding layer.

[0142] For example, referring to Figure 8, the horizontal axis represents the different viewing angles of the anti-peeping pixel area, and the vertical axis represents the relative light intensity of the two display panels (other structures being the same) with and without the lens structure at different viewing angles. By comparison, it can be seen that after the display panel of the embodiment shown in Figure 7 is provided with the lens structure, the brightness of the anti-peeping pixel area in the positive viewing angle range (for example, -20° to 20°, or -30° to 30°) is greatly improved. For example, the brightness near the 0° viewing angle is increased by approximately 300%, which is conducive to further improving the display effect of the display panel in anti-peeping mode.

[0143] FIG11 is a partial schematic plan view of a touch layer according to an exemplary embodiment of the present disclosure; FIG12 is a partial schematic plan view of a touch layer according to an exemplary embodiment of the present disclosure.

[0144] 11 and 12 , in some embodiments, the touch layer 5 includes independent touch electrodes 511 and dummy electrodes 512 , and at least a portion of the touch electrodes 511 and dummy electrodes 512 are reused as the third sub-light-shielding layer 203 .

[0145] Exemplarily, both the touch electrodes and the dummy electrodes are made of conductive materials, such as metal, but not limited thereto. The touch electrodes are used to drive or receive touch signals, enabling touch functionality. The dummy electrodes 512 comprise floating electrodes that do not receive electrical signals. It should be noted that the dummy electrodes can be provided or not depending on actual needs.

[0146] The touch electrodes 511 and the dummy electrodes 512 may be located in a single conductive layer, or in two stacked conductive layers.

[0147] By configuring the touch layer to include independent touch electrodes 511 and dummy electrodes 512, the touch signal strength is optimized and touch performance is enhanced. As shown in FIG11 , in some embodiments, the touch electrode 511 includes an effective electrode portion 5110 . The third sub-light shielding layer 203 included in the touch electrode 511 is coupled to the effective electrode portion 5110 .

[0148] The effective electrode portion 5110 is primarily used to implement the touch function. The third sub-light-shielding layer 203 included in the touch electrode is coupled to the effective electrode portion 5110. This allows the third sub-light-shielding layer 203 included in the touch electrode 511 to achieve the light-shielding function while also increasing the area of ​​the effective electrode portion, thereby increasing the touch signal volume, better optimizing the touch signal strength, and further improving touch performance.

[0149] In some embodiments, the orthographic projection of the third light-shielding sub-layer 203 included in the touch electrode on the base substrate is at least partially surrounded by the orthographic projection of the effective electrode portion 5110 on the base substrate.

[0150] The above configuration not only ensures the light shielding effect of the third sub-light shielding layer 203 , but also ensures that the effective electrode portion 5110 has sufficient layout space, thereby ensuring the touch effect of the touch display panel.

[0151] In some embodiments, referring to FIG. 12 , the dummy electrode 512 includes a dummy electrode portion 5120. The dummy electrode portion 5120 may be a floating electrode that receives no signal. The third sub-light-shielding layer 203 included in the dummy electrode 512 is coupled to at least a portion of the dummy electrode portion 5120. Alternatively, the third sub-light-shielding layer 203 included in the dummy electrode 512 is independent of the dummy electrode portion 5120.

[0152] The above different layouts can be selected according to actual needs. Regardless of whether the third sub-light shielding layer 203 included in the virtual electrode 512 is coupled to the virtual electrode portion 5120, it can optimize the touch signal strength and improve the touch performance.

[0153] For example, in some embodiments of the present disclosure, referring to FIG9 , the pixel defining layer PDL may be made of a black material. The encapsulation layer 3 may be a thin film encapsulation, such as a three-layer or multi-layer structure of inorganic / organic / inorganic. For example, the encapsulation layer 3 has a fourth thickness h4, and the fourth thickness h4 is between 2 microns and 20 microns, such as 8 microns to 20 microns, and may include endpoint values, but is not limited thereto. The touch layer 5 may be composed of one or more layers of metal grids. The touch layer 5 includes a plurality of metal traces. For example, the touch layer 5 includes a plurality of touch sub-lines 51 located between a plurality of anti-peep sub-pixels. The orthographic projection of at least a portion of the touch sub-lines 51 on the base substrate has a third width d3 along the first direction, and the third width d3 is between 2 microns and 4 microns. At least a portion of the plurality of metal traces is blackened near the lower surface of the base substrate, thereby reducing stray light.

[0154] A first protective layer 6 can also be provided above the touch layer 5. The thickness of the first protective layer 6 is between 2 microns and 5 microns, including endpoint values, but not limited thereto. The lens structure 7 can be a hemispherical or spherical crown structure. The second width d2 of the lens structure 7 is between 8 microns and 40 microns, including endpoint values, but not limited thereto. The lens structure is formed of a high refractive index material. For example, the refractive index of the material in the lens structure 7 is between 1.5 and 1.8, including endpoint values, but not limited thereto. The material around the lens structure 7 is a low refractive index material. Exemplarily, the display panel can also include a fourth covering layer 8, an optical adhesive layer 9, a cover plate 10 and a hardened protective layer 11 located above the lens structure 7. No further details will be given here.

[0155] Continuing with FIG9 , the display panel further includes a second sub-light-shielding layer 202 disposed between the touch layer 5 and the encapsulation layer 3. The second sub-light-shielding layer 202 includes a plurality of second sub-light-shielding portions 2021. The orthographic projection of at least one second sub-light-shielding portion 2021 on the base substrate has a sixth width d6 along the first direction. The sixth width d6 is between 4 microns and 20 microns, including but not limited to these values.

[0156] For example, the display panel may further include a second covering layer 13 located between the second light-shielding sub-layer 202 and the second protection layer 4. The second covering layer 13 may be a transparent insulating layer.

[0157] Exemplarily, the second sub-light-shielding layer 202 defines a plurality of second opening areas 212. The orthographic projection of the boundary of the anti-peeping pixel opening 32 on the substrate is surrounded by the orthographic projection of the boundary of the corresponding second opening area 212 on the substrate. Alternatively, the orthographic projection of the anti-peeping pixel opening 32 on the substrate at least partially overlaps with the orthographic projection of the second sub-light-shielding layer 202 on the substrate. For example, the distance between the orthographic projection of the boundary of the anti-peeping pixel opening 32 on the substrate and the orthographic projection of the boundary of the corresponding second opening area 212 on the substrate is between -3 microns and 10 microns, and can also be set between -1 micron and 10 microns, for example, between 0 and 6 microns, and the above ranges may include endpoint values.

[0158] It should be noted that when the above distance is a positive value, it means that the orthographic projection of the boundary of the anti-privacy pixel opening 32 on the base substrate does not overlap with the orthographic projection of the second sub-light-shielding layer 202 on the base substrate. When the above distance is a negative value, it means that the orthographic projection of the boundary of the anti-privacy pixel opening 32 on the base substrate overlaps with the orthographic projection of the second sub-light-shielding layer 202 on the base substrate.

[0159] For example, in some embodiments of the present disclosure, the second sub-light-shielding layer 202 has a second thickness h2, and the encapsulation layer 3 has a fourth thickness h4. The ratio of the second thickness h2 to the fourth thickness h4 is greater than or equal to 0.05 and less than or equal to 0.5. For example, the second thickness h2 is between 1 micron and 3 microns, and the fourth thickness h4 is between 2 microns and 20 microns, for example, 8 microns to 20 microns. The above ranges may include endpoints.

[0160] For example, referring to Figure 10, the horizontal axis represents the different viewing angles of the anti-peeping pixel area, and the vertical axis represents the relative light intensity of the two display panels (other structures are the same) with and without the lens structure at different viewing angles. By comparison, it can be seen that after the display panel of the embodiment shown in Figure 9 is provided with the lens structure, the brightness of the anti-peeping pixel area in the positive viewing angle range (for example, -20° to 20°, or -30° to 30°) is greatly improved. For example, the brightness near the 0° viewing angle is increased by about 300%, which is conducive to further improving the display effect of the display panel in anti-peeping mode.

[0161] FIG13 shows a partial cross-sectional schematic diagram of a display panel according to some other embodiments of the present disclosure, taken along line AA′ in FIG2 ; FIG14 shows a comparison diagram of light emission effects of the display panel with and without a lens structure in FIG13 .

[0162] For example, in some embodiments of the present disclosure, referring to FIG13 , the pixel defining layer PDL may be made of a black material. The encapsulation layer 3 may be a thin film encapsulation, such as a three-layer or multi-layer structure of inorganic / organic / inorganic. For example, the encapsulation layer 3 has a fourth thickness h4, and the fourth thickness h4 is between 2 microns and 20 microns, for example, 8 microns to 20 microns, and may include end point values, but is not limited thereto. The touch layer 5 may be composed of one or more layers of metal grids. The touch layer 5 includes a plurality of metal traces. For example, the touch layer 5 includes a plurality of touch sub-lines 51 located between a plurality of anti-peep sub-pixels. The orthographic projection of at least a portion of the touch sub-lines 51 on the substrate has a third width d3 along the first direction, and the third width d3 is between 2 microns and 4 microns. At least a portion of the plurality of metal traces is blackened near the lower surface of the substrate, thereby reducing stray light.

[0163] A first protective layer 6 can also be provided above the touch layer 5. The thickness of the first protective layer 6 is between 2 microns and 5 microns, including endpoint values, but not limited thereto. The lens structure 7 can be a hemispherical or spherical crown structure. The second width d2 of the lens structure 7 is between 8 microns and 40 microns, including endpoint values, but not limited thereto. The lens structure 7 is formed of a high refractive index material. For example, the refractive index of the material in the lens structure 7 is between 1.5 and 1.8, including endpoint values, but not limited thereto. The material around the lens structure 7 is a low refractive index material. Exemplarily, the display panel can also include a fourth covering layer 8, an optical adhesive layer 9, a cover plate 10 and a hardened protective layer 11 located above the lens structure 7. No further details will be given here.

[0164] Continuing with reference to Figure 13, the light-shielding layer may further include a first sub-light-shielding layer 201 located between the touch layer 5 and the lens structure 7. A first covering layer 12 may be filled between the lens structure 7 and the first sub-light-shielding layer 201. The first covering layer 12 may cover the upper surface of the first sub-light-shielding layer 201, so that the surface of the lens structure 7 close to the substrate and the surface of the first sub-light-shielding layer 201 away from the substrate are spaced apart. Here, the spaced apart arrangement means that the lens structure 7 is not in direct contact with the first sub-light-shielding layer 201. The first sub-light-shielding layer 201 includes a plurality of first sub-light-shielding portions 2011. The orthographic projection of at least one first sub-light-shielding portion 2011 on the substrate has a fifth width d5 ​​along the first direction. The fifth width d5 ​​is between 4 microns and 20 microns, and may include endpoint values, but is not limited thereto.

[0165] Exemplarily, the refractive index of the material in the first cover layer 12 is smaller than the refractive index of the material in the lens structure 7 , thereby achieving a better light focusing effect of the lens structure.

[0166] Exemplarily, the first sub-light-shielding layer 201 defines a plurality of first opening regions 211. The orthographic projection of the boundaries of the privacy-prevention pixel openings 32 on the base substrate is surrounded by the orthographic projection of the boundaries of the corresponding first opening regions 211 on the base substrate. Alternatively, the orthographic projection of the privacy-prevention pixel openings 32 on the base substrate at least partially overlaps with the orthographic projection of the first sub-light-shielding layer 201 on the base substrate.

[0167] Continuing with FIG13 , the light-shielding layer may further include a second sub-light-shielding layer 202 between the touch layer 5 and the encapsulation layer 3. The second sub-light-shielding layer 202 includes a plurality of second sub-light-shielding portions 2021. The orthographic projection of at least one second sub-light-shielding portion 2021 on the base substrate has a sixth width d6 along the first direction. The sixth width d6 is between 4 microns and 20 microns, including but not limited to these values.

[0168] For example, the display panel may further include a second covering layer 13 located between the second light-shielding sub-layer 202 and the second protective layer 4. Both the second protective layer 4 and the second covering layer 13 may be transparent insulating layers.

[0169] Exemplarily, the second light-shielding sub-layer 202 defines a plurality of second opening regions 212. The orthographic projection of the boundaries of the privacy-prevention pixel openings 32 on the base substrate is surrounded by the orthographic projection of the boundaries of the corresponding second opening regions 212 on the base substrate. Alternatively, the orthographic projection of the privacy-prevention pixel openings 32 on the base substrate at least partially overlaps with the orthographic projection of the second light-shielding sub-layer 202 on the base substrate.

[0170] For example, the orthographic projections of the first sub-light-shielding layer 201 and the second sub-light-shielding layer 202 corresponding to the same privacy pixel opening on the base substrate may completely overlap. Alternatively, the orthographic projections of the first sub-light-shielding layer 201 and the second sub-light-shielding layer 202 corresponding to the same privacy pixel opening on the base substrate may at least partially overlap.

[0171] For example, in some embodiments of the present disclosure, the first sub-light-shielding layer 201 has a first thickness h1, and the encapsulation layer 3 has a fourth thickness h4. The ratio of the first thickness h1 to the fourth thickness h4 is greater than or equal to 0.05 and less than or equal to 0.5. For example, the first thickness h1 is between 1 micron and 3 microns, and the fourth thickness h4 is between 2 microns and 20 microns, for example, 8 microns to 20 microns. The above ranges may include endpoints.

[0172] For example, in some embodiments of the present disclosure, the second sub-light-shielding layer 202 has a second thickness h2, and the encapsulation layer 3 has a fourth thickness h4. The ratio of the second thickness h2 to the fourth thickness h4 is greater than or equal to 0.05 and less than or equal to 0.5. For example, the second thickness h2 is between 1 micron and 3 microns, and the fourth thickness h4 is between 2 microns and 20 microns, for example, 8 microns to 20 microns. The above ranges may include endpoints.

[0173] Through the combined design of the first sub-light-shielding layer 201 and the second sub-light-shielding layer 202, the light emitted by the anti-peeping sub-pixel is sequentially emitted from the second opening area 212 and the first opening area 211 toward the light-emitting side of the display panel, thereby enabling the display panel to achieve an anti-peeping mode through the anti-peeping sub-pixel.

[0174] For example, referring to Figure 14, the horizontal axis represents the different viewing angles of the privacy-prevention pixel area, and the vertical axis represents the relative light intensity of two display panels (other structures being the same) with and without a lens structure at different viewing angles. By comparison, it can be seen that, for the display panel of the embodiment shown in Figure 13, after the lens structure is installed, the brightness of the privacy-prevention pixel area in the normal viewing angle range (e.g., -10° to 10°, or -20° to 20°) is greatly improved. For example, the brightness near a 0° viewing angle is increased by approximately 300%.

[0175] Compared to display panels with a single light-shielding layer, display panels with a double light-shielding layer have a more concentrated light output angle in the anti-privacy pixel area, further reducing the viewing angle. The light output intensity approaches zero in a wider viewing angle range (for example, -90° to -30° and 30° to 90°). The double light-shielding layer design further optimizes the light output effect in the anti-privacy pixel area, further reducing the viewing angle and increasing the front light output intensity, thereby achieving a better anti-privacy display effect.

[0176] FIG15 shows a partial cross-sectional schematic diagram of a display panel taken along line AA′ in FIG2 according to some other embodiments of the present disclosure; FIG16 shows a comparison diagram of light emission effects of the display panel with and without a lens structure in FIG15 .

[0177] For example, in some embodiments of the present disclosure, referring to FIG15 , the pixel defining layer PDL may be made of a black material. The encapsulation layer 3 may be a thin film encapsulation, such as a three-layer or multi-layer structure of inorganic / organic / inorganic. For example, the encapsulation layer has a fourth thickness h4, and the fourth thickness h4 is between 2 microns and 20 microns, such as 8 microns to 20 microns, and may include end point values, but is not limited thereto. The touch layer 5 may be composed of one or more layers of metal grids. The touch layer 5 includes a plurality of metal traces, and at least a portion of the plurality of metal traces is blackened near the lower surface of the substrate, thereby reducing stray light. Among them, at least a portion of the plurality of metal traces is reused as a third sub-light-shielding layer 203. The third sub-light-shielding layer 203 defines a plurality of third opening areas 213, wherein the orthographic projection of the third opening area 213 on the substrate at least partially overlaps with the orthographic projection of the corresponding lens structure 7 on the substrate.

[0178] 15 , the third sub-light-shielding layer 203 may include a plurality of third sub-light-shielding portions 2031. The orthographic projections of the third sub-light-shielding portions 2031 on the base substrate define corresponding third opening areas 213. The orthographic projections of the third sub-light-shielding portions 2031 on the base substrate at least partially overlap with the orthographic projections of the lens structure 7 on the base substrate.

[0179] Exemplarily, the orthographic projection of the boundary of the privacy pixel opening 32 on the substrate is surrounded by the orthographic projection of the boundary of the corresponding third opening area 213 on the substrate. Alternatively, the orthographic projection of the privacy pixel opening 32 on the substrate at least partially overlaps with the orthographic projection of the third sub-light-shielding layer 203 on the substrate. For example, the distance between the orthographic projection of the boundary of the privacy pixel opening 32 on the substrate and the orthographic projection of the boundary of the corresponding third opening area 213 on the substrate is between -3 microns and 10 microns, and can also be set between -1 micron and 10 microns, for example, between 0 and 6 microns, and the above ranges may include endpoint values.

[0180] A first protective layer 6 may also be provided above the touch layer 5. The thickness of the first protective layer 6 may be between 2 microns and 5 microns, including but not limited to these values. The lens structure 7 may be a hemispherical or spherical cap structure. The second width d2 of the lens structure may be between 8 microns and 40 microns, including but not limited to these values. The lens structure 7 is formed of a high refractive index material. For example, the refractive index of the material in the lens structure 7 may be between 1.5 and 1.8, including but not limited to these values. The material surrounding the lens structure 7 is a low refractive index material. This will not be further described here.

[0181] Continuing with FIG. 15 , an orthographic projection of at least a portion of the third sub-light-shielding portion 2031 onto the substrate has a fourth width d4 along the first direction. The ratio of the fourth width d4 to the second width d2 is between 0.2 and 0.8, for example, approximately 0.5. For example, the fourth width d4 is between 4 micrometers and 20 micrometers, inclusive, but not limited thereto.

[0182] Continuing with FIG. 15 , the light-shielding layer may further include a second sub-light-shielding layer 202 between the touch layer 5 and the encapsulation layer 3. The second sub-light-shielding layer 202 includes a plurality of second sub-light-shielding portions 2021. The orthographic projection of at least one second sub-light-shielding portion 2021 on the base substrate has a sixth width d6 along the first direction. The sixth width d6 is between 4 microns and 20 microns, including but not limited to these values.

[0183] For example, the display panel may further include a second covering layer 13 located between the second light-shielding sub-layer 202 and the second protection layer 4. The second covering layer 13 may be a transparent insulating layer.

[0184] Exemplarily, the second light-shielding sub-layer 202 defines a plurality of second opening regions 212. The orthographic projection of the boundaries of the privacy-prevention pixel openings 32 on the base substrate is surrounded by the orthographic projection of the boundaries of the corresponding second opening regions 212 on the base substrate. Alternatively, the orthographic projection of the privacy-prevention pixel openings 32 on the base substrate at least partially overlaps with the orthographic projection of the second light-shielding sub-layer 202 on the base substrate.

[0185] Exemplarily, the orthographic projections of the third sub-light-shielding layer 203 and the second sub-light-shielding layer 202 corresponding to the same anti-peeping pixel opening on the base substrate completely overlap.

[0186] Exemplarily, the orthographic projections of the third sub-light-shielding layer 203 and the second sub-light-shielding layer 202 corresponding to the same anti-peeping pixel opening on the base substrate at least partially overlap.

[0187] Through the combined design of the second sub-light-shielding layer 202 and the third sub-light-shielding layer 203, light emitted by the anti-peeping sub-pixel is sequentially emitted from the second opening area 212 and the third opening area 213 toward the light-emitting side of the display panel, thereby enabling the display panel to achieve an anti-peeping mode through the anti-peeping sub-pixel. At the same time, by reusing at least a portion of the touch layer as the third sub-light-shielding layer 203, the formation of a third sub-light-shielding layer 203 specifically for light shielding within the touch display panel is avoided, the number of film layers within the touch display panel is reduced, and the internal structure of the touch display panel is optimized. This solves the problems of complex structure, large product thickness, and high production costs when implementing the switch between anti-peeping mode and shared screen information mode in display products.

[0188] For example, referring to Figure 16, the horizontal axis represents the different viewing angles of the privacy-prevention pixel area, and the vertical axis represents the relative light intensity of two display panels (other structures being the same) with and without a lens structure at different viewing angles. By comparison, it can be seen that, for the display panel of the embodiment shown in Figure 15, after the lens structure is installed, the brightness of the privacy-prevention pixel area in the normal viewing angle range (e.g., -10° to 10°, or -20° to 20°) is greatly improved. For example, the brightness near a 0° viewing angle is increased by approximately 300%.

[0189] Compared to display panels with a single light-shielding layer, display panels with a double light-shielding layer have a more concentrated light output angle in the anti-privacy pixel area, further reducing the viewing angle. The light output intensity approaches zero in a wider viewing angle range (for example, -90° to -30° and 30° to 90°). The double light-shielding layer design further optimizes the light output effect in the anti-privacy pixel area, further reducing the viewing angle and increasing the front light output intensity, thereby achieving a better anti-privacy display effect.

[0190] FIG. 17 shows a partial cross-sectional schematic diagram of a display panel according to some other embodiments of the present disclosure, taken along line AA′ in FIG. 2 .

[0191] For example, in some embodiments of the present disclosure, referring to FIG17 , the pixel defining layer PDL may be made of a black material or a transparent material. The encapsulation layer 3 may be a thin film encapsulation, such as a three-layer or multi-layer structure of inorganic / organic / inorganic. For example, the encapsulation layer has a fourth thickness h4, and the fourth thickness h4 is between 2 microns and 20 microns, for example, 6 microns to 20 microns, and may include endpoint values, but is not limited thereto. The touch layer 5 may be composed of one or more layers of metal grids. The touch layer 5 includes a plurality of metal traces. For example, the touch layer 5 includes a plurality of touch sub-lines 51 located between a plurality of anti-peep sub-pixels. The orthographic projection of at least a portion of the touch sub-lines 51 on the substrate has a third width d3 along the first direction, and the third width d3 is between 2 microns and 4 microns.

[0192] Illustratively, at least a portion of the plurality of metal traces is blackened near the lower surface of the substrate, thereby reducing stray light.

[0193] For example, the plurality of metal traces close to the lower surface of the substrate may not be blackened.

[0194] A first protective layer 6 may be disposed above the touch layer 5. The first protective layer 6 may include a single organic layer or a stacked structure of inorganic layer / organic layer / inorganic layer. For example, the first protective layer 6 may include a single inorganic layer, such as SiNx; or it may include a stacked structure of multiple inorganic layers, such as a SiNx / SiOx stacked layer. For example, the thickness of the first protective layer 6 may be between 0.1 microns and 5 microns, inclusive, but not limited to these values.

[0195] The lens structure 7 can be a hemispherical or spherical cap structure. The second width d2 of the lens structure is between 6 microns and 40 microns, including endpoint values, but not limited to them. The lens structure is formed of a high refractive index material. For example, the refractive index of the material in the lens structure 7 is between 1.5 and 1.8, including endpoint values, but not limited to them. The material around the lens structure 7 is a low refractive index material. Exemplarily, the display panel may further include a fourth covering layer 8, an optical adhesive layer 9, a cover plate 10 and a hardened protective layer 11 located above the lens structure 7. No further details are given here.

[0196] Continuing to refer to FIG. 17 , the light shielding layer may further include a first sub-light shielding layer 201 located between the touch layer 5 and the lens structure 7 .

[0197] For example, at least a portion of the first light-shielding sub-layer 201 may be in direct contact with the lens structure 7 .

[0198] For example, referring to FIG13 , a first cover layer 12 may be filled between the first sub-light-shielding layer 201 and the lens structure 7. The first cover layer 12 may cover the upper surface of the first sub-light-shielding layer 201, thereby spacing the lens structure 7 closer to the substrate surface and the first sub-light-shielding layer 201 further from the substrate surface. "Separated" means that the lens structure 7 is not in direct contact with the first sub-light-shielding layer 201.

[0199] The orthographic projection of the first light-shielding portion 2011 on the base substrate has a fifth width d5 ​​along the first direction, which is between 4 micrometers and 20 micrometers, including but not limited to the end values.

[0200] Exemplarily, the first sub-light-shielding layer 201 defines a plurality of first opening areas 211. The orthographic projection of the boundary of the privacy-prevention pixel opening 32 on the substrate is surrounded by the orthographic projection of the boundary of the corresponding first opening area 211 on the substrate. Alternatively, the orthographic projection of the privacy-prevention pixel opening 32 on the substrate at least partially overlaps with the orthographic projection of the first sub-light-shielding layer 201 on the substrate. For example, the distance between the orthographic projection of the boundary of the privacy-prevention pixel opening 32 on the substrate and the orthographic projection of the boundary of the corresponding first opening area 211 on the substrate is between -1 micron and 10 microns, for example, between 0 and 8 microns, and the above ranges may include endpoint values.

[0201] Exemplarily, the first light-shielding sub-layer 201 includes a third surface 2010 close to the base substrate, and a third spacing distance H3 is spaced apart from the first surface EL1 and the third surface 2010. The third spacing distance H3 is less than or equal to the first spacing distance H1.

[0202] Exemplarily, the third spacing distance H3 is between 10 micrometers and 30 micrometers, for example, between 12 micrometers and 20 micrometers, and the above ranges may include endpoint values.

[0203] Exemplarily, the first sub-light-shielding layer 201 has a first thickness h1, and the encapsulation layer 3 has a fourth thickness h4. The ratio of the first thickness h1 to the fourth thickness h4 is greater than or equal to 0.05 and less than or equal to 0.5. For example, the first thickness h1 is between 1 micron and 3 microns, and the fourth thickness h4 is between 2 microns and 20 microns, for example, 8 microns to 20 microns. These ranges may include endpoints.

[0204] Continuing with FIG. 17 , the light-shielding layer may further include a second sub-light-shielding layer 202 between the touch layer 5 and the encapsulation layer 3. The second sub-light-shielding layer 202 includes a plurality of second sub-light-shielding portions 2021. The orthographic projection of at least one second sub-light-shielding portion 2021 on the base substrate has a sixth width d6 along the first direction. The sixth width d6 is between 4 microns and 20 microns, including but not limited to these values.

[0205] For example, the display panel may further include a second covering layer 13 located between the second light-shielding sub-layer 202 and the second protection layer 4. The second covering layer 13 may be a transparent insulating layer.

[0206] Exemplarily, the second sub-light-shielding layer 202 defines a plurality of second opening areas 212. The orthographic projection of the boundary of the privacy-prevention pixel opening 32 on the substrate is surrounded by the orthographic projection of the boundary of the corresponding second opening area 212 on the substrate. Alternatively, the orthographic projection of the privacy-prevention pixel opening 32 on the substrate at least partially overlaps with the orthographic projection of the second sub-light-shielding layer 202 on the substrate. For example, the distance between the orthographic projection of the boundary of the privacy-prevention pixel opening 32 on the substrate and the orthographic projection of the boundary of the corresponding second opening area 212 on the substrate is between -3 microns and 10 microns, for example, between 0 and 6 microns, and the above ranges may include endpoint values.

[0207] Exemplarily, the second light-shielding sub-layer 202 includes a fourth surface 2020 close to the base substrate, and a fourth distance H4 is spaced between the first surface EL1 and the fourth surface 2020. The ratio of the fourth distance H4 to the first width d1 is greater than or equal to 1 and less than or equal to 2.

[0208] Exemplarily, the fourth spacing distance H4 is between 6 micrometers and 12 micrometers, for example, between 8 micrometers and 10 micrometers, and the first width is less than or equal to 6 micrometers. The above ranges may include endpoint values.

[0209] Illustratively, a ratio of the fourth spacing distance H4 to the third spacing distance H3 is greater than or equal to 0.2 and less than or equal to 0.85.

[0210] By reducing the distances between the first and second sub-light-shielding layers and the light-emitting layer, the distance between the lens above the light-shielding layer and the light-emitting layer can be correspondingly reduced, which is beneficial to the convergence of light and thus achieves a better anti-peeping display effect.

[0211] For example, the orthographic projection of the first sub-light-shielding layer 201 corresponding to the same privacy-prevention pixel opening on the substrate falls within the orthographic projection of the corresponding second sub-light-shielding layer 202 on the substrate. In other words, the first opening area 211 has a larger opening range than the second opening area 212. By optimizing the sizes of the first and second opening areas, light can be better controlled to be emitted toward the area where the lens structure is located, thereby improving display brightness in the privacy-prevention state.

[0212] For example, in some embodiments of the present disclosure, the first sub-light-shielding layer 201 has a first thickness h1, and the encapsulation layer 3 has a fourth thickness h4. The ratio of the first thickness h1 to the fourth thickness h4 is greater than or equal to 0.05 and less than or equal to 0.5. For example, the first thickness h1 is between 1 micron and 3 microns, and the fourth thickness h4 is between 2 microns and 20 microns, for example, 8 microns to 20 microns. The above ranges may include endpoints.

[0213] For example, in some embodiments of the present disclosure, the second sub-light-shielding layer 202 has a second thickness h2, and the encapsulation layer 3 has a fourth thickness h4. The ratio of the second thickness h2 to the fourth thickness h4 is greater than or equal to 0.05 and less than or equal to 0.5. For example, the second thickness h2 is between 1 micron and 3 microns, and the fourth thickness h4 is between 2 microns and 20 microns, for example, 8 microns to 20 microns. The above ranges may include endpoints.

[0214] Through the combined design of the first sub-light-shielding layer 201 and the second sub-light-shielding layer 202, the light emitted by the anti-peeping sub-pixel is sequentially emitted from the second opening area 212 and the first opening area 211 toward the light-emitting side of the display panel, thereby enabling the display panel to achieve an anti-peeping mode through the anti-peeping sub-pixel.

[0215] Compared to display panels with a single light-shielding layer, display panels with a double light-shielding layer have a more concentrated light emission angle in the anti-privacy pixel area, further reducing the viewing angle. The light emission intensity approaches zero in a wider viewing angle range (for example, -90° to -30° and 30° to 90°). The double light-shielding layer can include different opening areas. By optimizing the opening area sizes corresponding to the upper and lower light-shielding layers, the light emission effect of the anti-privacy pixel area can be further optimized, which can further reduce the viewing angle and increase the light emission intensity from the front, thereby achieving a better anti-privacy display effect.

[0216] FIG. 18 shows a partial cross-sectional schematic diagram of a display panel according to some other embodiments of the present disclosure, taken along line AA′ in FIG. 2 .

[0217] For example, in some embodiments of the present disclosure, referring to FIG18 , the pixel defining layer PDL may be made of black material or transparent material. The encapsulation layer 3 may be a thin film encapsulation, such as a three-layer or multi-layer structure such as inorganic / organic / inorganic. For example, the encapsulation layer has a fourth thickness h4, and the fourth thickness h4 is between 2 microns and 20 microns, such as 6 microns to 20 microns, and may include endpoint values, but is not limited thereto. The touch layer 5 may be composed of one or more layers of metal grids. The touch layer 5 includes a plurality of metal traces. Among them, at least a portion of the plurality of metal traces is reused as a third sub-light-shielding layer 203. The third sub-light-shielding layer 203 defines a plurality of third opening areas 213, wherein the orthographic projection of the third opening area 213 on the substrate substrate at least partially overlaps with the orthographic projection of the corresponding lens structure 7 on the substrate substrate.

[0218] Exemplarily, the light-emitting layer of the privacy-prevention sub-pixel includes a first surface EL1 distal from the base substrate, and the lens structure 7 includes a second surface 71 proximal to the base substrate. A first spacing distance H1 is separated from the first surface EL1 and the second surface 71. The first spacing distance H1 is less than twice the fourth thickness h4. For example, the first spacing distance is 14 microns, and the fourth thickness is 8 microns.

[0219] Exemplarily, the first spacing distance H1 is less than 2 times the fourth thickness h4. For example, the first spacing distance H1 is 14 micrometers, and the fourth thickness h4 is 8 micrometers.

[0220] 18 , the third sub-light-shielding layer 203 may include a plurality of third sub-light-shielding portions 2031. The plurality of third sub-light-shielding portions 2031 define corresponding third opening areas 213. The orthographic projections of the third sub-light-shielding portions 2031 on the base substrate at least partially overlap with the orthographic projections of the lens structure 7 on the base substrate.

[0221] Exemplarily, the orthographic projection of the boundary of the privacy pixel opening 32 on the substrate is surrounded by the orthographic projection of the boundary of the corresponding third opening area 213 on the substrate. Alternatively, the orthographic projection of the privacy pixel opening 32 on the substrate at least partially overlaps with the orthographic projection of the third sub-light-shielding layer 203 on the substrate. For example, the distance between the orthographic projection of the boundary of the privacy pixel opening 32 on the substrate and the orthographic projection of the boundary of the corresponding third opening area 213 on the substrate is between -1 micron and 10 microns, for example, between 0 and 8 microns, and the above ranges may include endpoints.

[0222] Continuing with FIG18 , an orthographic projection of at least a portion of the third light-shielding portion 2031 onto the substrate has a fourth width d4 along the first direction. A ratio of the fourth width d4 to the second width d2 is between 0.2 and 0.8, for example, approximately 0.5. For example, the fourth width d4 is between 3 micrometers and 20 micrometers, inclusive, but not limited thereto.

[0223] Exemplarily, the third sub-light-shielding layer 203 has a third thickness h3. The ratio of the third thickness h3 to the fourth thickness h4 is greater than or equal to 0.005 and less than or equal to 0.5. For example, the third thickness h3 is between 0.1 microns and 3 microns, and the fourth thickness h4 is between 2 microns and 20 microns, for example, 8 microns to 20 microns. These ranges may include endpoints. By making the third sub-light-shielding layer 203 thinner, the film flatness can be increased, which facilitates the formation of the lens structure above the light-shielding layer.

[0224] Exemplarily, the third sub-light-shielding layer 203 includes a fifth surface 2030 close to the base substrate, and a fifth spacing distance H5 is spaced apart from the first surface EL1 and the fifth surface 2030. The fifth spacing distance H5 is between 10 micrometers and 30 micrometers, for example, between 12 micrometers and 20 micrometers.

[0225] A first protective layer 6 may be disposed above the touch layer 5. The first protective layer 6 may comprise a single organic layer or an inorganic / organic / inorganic stack. For example, the first protective layer 6 may comprise a single inorganic layer, such as SiNx; or the first protective layer 6 may comprise a stack of multiple inorganic layers, such as a SiNx / SiOx stack. For example, the thickness of the first protective layer 6 may be between 0.1 microns and 5 microns, inclusive, but not limited to these values.

[0226] The lens structure 7 can be a hemispherical or spherical cap structure. The second width d2 of the lens structure 7 is between 6 microns and 40 microns, including endpoint values, but not limited to these. The lens structure is formed of a high refractive index material. For example, the refractive index of the material in the lens structure 7 is between 1.5 and 1.8, including endpoint values, but not limited to these. The material around the lens structure 7 is a low refractive index material. Exemplarily, the display panel may further include a fourth covering layer 8, an optical adhesive layer 9, a cover plate 10, and a hardened protective layer 11 located above the lens structure 7. No further details are given here.

[0227] Continuing with FIG. 18 , the light-shielding layer may further include a second sub-light-shielding layer 202 between the touch layer 5 and the encapsulation layer 3. The second sub-light-shielding layer 202 includes a plurality of second sub-light-shielding portions 2021. The orthographic projections of the second sub-light-shielding portions 2021 on the base substrate have a sixth width d6 along the first direction. The sixth width d6 is between 4 microns and 20 microns, including but not limited to these values.

[0228] For example, the display panel may further include a second covering layer 13 located between the second light-shielding sub-layer 202 and the second protection layer 4. The second covering layer 13 may be a transparent insulating layer.

[0229] Exemplarily, the second sub-light-shielding layer 202 defines a plurality of second opening areas 212. The orthographic projection of the boundary of the privacy-prevention pixel opening 32 on the substrate is surrounded by the orthographic projection of the boundary of the corresponding second opening area 212 on the substrate. Alternatively, the orthographic projection of the privacy-prevention pixel opening 32 on the substrate at least partially overlaps with the orthographic projection of the second sub-light-shielding layer 202 on the substrate. For example, the distance between the orthographic projection of the boundary of the privacy-prevention pixel opening 32 on the substrate and the orthographic projection of the boundary of the corresponding second opening area 212 on the substrate is between -3 microns and 10 microns, for example, between 0 and 6 microns, and the above ranges may include endpoint values.

[0230] Exemplarily, the second light-shielding sub-layer 202 includes a fourth surface 2020 close to the base substrate, and a fourth distance H4 is spaced between the first surface EL1 and the fourth surface 2020. The ratio of the fourth distance H4 to the first width d1 is greater than or equal to 1 and less than or equal to 2.

[0231] Exemplarily, the fourth spacing distance H4 is between 6 micrometers and 12 micrometers, for example, between 8 micrometers and 10 micrometers, and the first width d1 is less than or equal to 6 micrometers. The above ranges may include endpoint values.

[0232] Illustratively, the ratio of the fourth spacing distance H4 to the fifth spacing distance H5 is greater than or equal to 0.2 and less than or equal to 0.85.

[0233] By reducing the distances between the third sub-light-shielding layer 203 and the second sub-light-shielding layer 202 and the light-emitting layer EL, the distance between the lens above the light-shielding layer and the light-emitting layer can be correspondingly reduced, which is beneficial to the convergence of light and thus achieves a better anti-peeping display effect.

[0234] For example, the orthographic projection of the third sub-light-shielding layer 203 corresponding to the same privacy-prevention pixel opening on the substrate falls within the orthographic projection of the corresponding second sub-light-shielding layer 202 on the substrate. In other words, the third opening area 213 has a larger opening range than the second opening area 212. By optimizing the sizes of the third and second opening areas, light can be better controlled to be emitted toward the area where the lens structure is located, thereby improving display brightness in the privacy-prevention state.

[0235] For example, in some embodiments of the present disclosure, the second sub-light-shielding layer 202 has a second thickness h2, and the encapsulation layer 3 has a fourth thickness h4. The ratio of the second thickness h2 to the fourth thickness h4 is greater than or equal to 0.05 and less than or equal to 0.5. For example, the second thickness h2 is between 1 micron and 3 microns, and the fourth thickness h4 is between 2 microns and 20 microns, for example, 8 microns to 20 microns. The above ranges may include endpoints.

[0236] Through the combined design of the third sub-light-shielding layer 203 and the second sub-light-shielding layer 202, the light emitted by the anti-peeping sub-pixel is sequentially emitted from the second opening area 212 and the third opening area 213 toward the light-emitting side of the display panel, thereby enabling the display panel to achieve an anti-peeping mode through the anti-peeping sub-pixel.

[0237] Compared to display panels with a single light-shielding layer, display panels with a double light-shielding layer have a more concentrated light emission angle in the anti-privacy pixel area, further reducing the viewing angle. The light emission intensity approaches zero in a wider viewing angle range (for example, -90° to -30° and 30° to 90°). The double light-shielding layer can include different opening areas. By optimizing the opening area sizes corresponding to the upper and lower light-shielding layers, the light emission effect of the anti-privacy pixel area can be further optimized, which can further reduce the viewing angle and increase the light emission intensity from the front, thereby achieving a better anti-privacy display effect.

[0238] By reusing at least a portion of the touch layer as the third sub-light-shielding layer 203, the formation of a dedicated third sub-light-shielding layer 203 within the touch display panel is avoided. This reduces the number of film layers within the touch display panel, optimizes the internal structure of the touch display panel, and addresses the complex structure, thick product thickness, and high manufacturing costs associated with switching between anti-peeping mode and shared screen information mode in display products. Reusing at least a portion of the touch layer as the third sub-light-shielding layer 203 also allows the third sub-light-shielding layer to be thinner, which helps improve its flatness and facilitates the formation of the lens structure above it.

[0239] FIG. 19 shows a partial cross-sectional schematic diagram of a display panel according to some other embodiments of the present disclosure, taken along line AA′ in FIG. 2 .

[0240] For example, similar to the display panel in the embodiment of FIG18 , the display panel in FIG19 may also include a third sub-light-shielding layer 203, a second sub-light-shielding layer 202, a pixel-defining layer PDL, an encapsulation layer 3, a touch layer 5, and a lens structure 7, wherein at least a portion of the touch layer is reused as the third sub-light-shielding layer 203. The openings of the third sub-light-shielding layer 203 and the second sub-light-shielding layer 202 are arranged in the same manner, and the distances between the third sub-light-shielding layer 203 and the second sub-light-shielding layer 202 and the light-emitting layer are also arranged in the same manner, which will not be repeated here.

[0241] Different from the display panel of FIG. 18 , the material of the second light-shielding sub-layer 202 includes a metal material, and the reflectivity of the metal material of the second light-shielding sub-layer is greater than or equal to 20%.

[0242] The second sub-light-shielding layer 202 has a second thickness h2, and the encapsulation layer 3 has a fourth thickness h4. The ratio of the second thickness h2 to the fourth thickness h4 is greater than or equal to 0.005 and less than or equal to 0.5. For example, the second thickness h2 is between 0.1 micrometers and 3 micrometers, and the fourth thickness h4 is between 2 micrometers and 20 micrometers, for example, 8 micrometers to 20 micrometers. These ranges may include endpoints.

[0243] By designing the second sub-light-shielding layer to be a thinner metal layer and reducing the thickness of the third sub-light-shielding layer, the flatness of the film layer can be further increased, which is beneficial to the formation of the upper lens structure.

[0244] FIG. 20 shows a partial cross-sectional schematic diagram of a display panel according to some other embodiments of the present disclosure, taken along line AA′ in FIG. 2 .

[0245] For example, similar to the display panel in the embodiment of FIG18 , the display panel in FIG20 may also include a third light-shielding sub-layer 203, a second light-shielding sub-layer 202, a pixel-defining layer PDL, an encapsulation layer 3, a touch layer 5, and a lens structure 7, wherein at least a portion of the touch layer is reused as the third light-shielding sub-layer 203. Detailed description is omitted here.

[0246] Different from the display panel in FIG. 18 , at least a portion of the third light-shielding sub-layer 203 may be in direct contact with the lens structure 7 .

[0247] The design of the third sub-light-shielding layer 203 being in direct contact with the lens structure 7 can reduce a covering layer in the middle, which is beneficial to reducing the distance between the lens structure and the light-emitting layer, and can improve the focusing effect of the lens structure to achieve better display.

[0248] FIG. 21 illustrates the structure of a portion of a display panel according to some embodiments of the present disclosure.

[0249] For example, in some embodiments of the present disclosure, the display panel may include a plurality of shared pixel units and a plurality of anti-peeping pixel units, wherein the shared pixel units and the anti-peeping pixel units are arranged correspondingly.

[0250] Exemplarily, referring to FIG. 21 , the shared pixel unit PX may include a plurality of first sub-pixels sp1 , a single second sub-pixel sp2 , and a plurality of third sub-pixels sp3 .

[0251] In some embodiments, the shared pixel unit PX may include a single first sub-pixel sp1 , a single second sub-pixel sp2 , and a plurality of third sub-pixels sp3 .

[0252] In some embodiments, the shared pixel unit PX may include a plurality of first sub-pixels sp1 , a plurality of second sub-pixels sp2 , and a plurality of third sub-pixels sp3 .

[0253] In some embodiments, the shared pixel unit PX may include a plurality of first sub-pixels sp1 , a plurality of second sub-pixels sp2 , and a single third sub-pixel sp3 .

[0254] The number of the first sub-pixel, the second sub-pixel, and the third sub-pixel in the shared pixel unit can be specifically set according to actual needs, and the embodiments of the present disclosure do not impose specific limitations on this.

[0255] Exemplarily, the privacy protection pixel unit PX′ may include a plurality of fourth sub-pixels sp1 ′, a plurality of fifth sub-pixels sp2 ′, and a plurality of sixth sub-pixels sp3 ′.

[0256] Exemplarily, continuing to refer to Figure 21, the plurality of first sub-pixels sp1 and the plurality of fourth sub-pixels sp1' are sub-pixels that emit light of the same color, for example, the plurality of first sub-pixels sp1 and the plurality of fourth sub-pixels sp1' all emit green light. Exemplarily, the number of the plurality of first sub-pixels sp1 is less than the number of the plurality of fourth sub-pixels sp1'. For example, for a single shared pixel unit, the number of first sub-pixels sp1 is 2. For a single anti-peeping pixel unit, the number of fourth sub-pixels sp1' is 11. The plurality of first sub-pixels sp1 can be spaced apart in the first direction X and aligned in the second direction Y. In the corresponding anti-peeping pixel unit, the plurality of fourth sub-pixels sp1' are located in three side areas adjacent to the plurality of first sub-pixels sp1. For example, the plurality of fourth sub-pixels sp1' can surround the plurality of first sub-pixels sp1 in a U-shape.

[0257] Exemplarily, the second subpixel sp2 and the plurality of fifth subpixels sp2' are subpixels emitting the same color light. For example, the second subpixel sp2 and the plurality of fifth subpixels sp2' all emit red light. The plurality of fifth subpixels sp2' are located in a side region adjacent to the second subpixel sp2. For example, the plurality of fifth subpixels sp2' are located in a side region of the second subpixel sp2 that is adjacent to the third subpixel sp3. Exemplarily, the plurality of fifth subpixels sp2' and the second subpixel sp2 are substantially aligned in the second direction Y.

[0258] Exemplarily, the plurality of third sub-pixels sp3 and the plurality of sixth sub-pixels sp3' are sub-pixels emitting the same color light. For example, the plurality of third sub-pixels sp3 and the plurality of sixth sub-pixels sp3' all emit blue light. Exemplarily, the number of the plurality of third sub-pixels sp3 is less than the number of the plurality of sixth sub-pixels sp3'. For example, for a single shared pixel unit, the number of third sub-pixels sp3 is 2. For a single privacy-protection pixel unit, the number of sixth sub-pixels sp3' is 12. The plurality of third sub-pixels sp1 can be spaced apart in the first direction X and aligned in the second direction Y.

[0259] The plurality of sixth sub-pixels sp3' are located in two side regions adjacent to the plurality of third sub-pixels sp3, wherein the two side regions are located on opposite sides of the third sub-pixel sp3. For example, a portion of the plurality of sixth sub-pixels sp3' may be located in an upper region of the third sub-pixel sp3, and another portion of the plurality of sixth sub-pixels sp3' may be located in a lower region of the third sub-pixel sp3. Exemplarily, the plurality of sixth sub-pixels sp3' and the plurality of third sub-pixels sp3 are substantially aligned in the first direction X.

[0260] For example, within a privacy-prevention pixel unit, for multiple privacy-prevention sub-pixels of different colors, the total area of ​​the pixel openings of the multiple privacy-prevention sub-pixels of each color can be different. For example, the total area of ​​the privacy-prevention pixel openings of the multiple sixth sub-pixels sp3' is greater than the total area of ​​the privacy-prevention pixel openings of the multiple fourth sub-pixels sp1', and is also greater than the total area of ​​the privacy-prevention pixel openings of the multiple fifth sub-pixels sp2'. For example, the multiple sixth sub-pixels sp3' can emit blue light, the multiple fourth sub-pixels sp1' can emit green light, and the multiple fifth sub-pixels sp2' can emit red light.

[0261] For example, within a shared pixel unit, the total area of ​​the pixel openings of shared sub-pixels of different colors can be different. For example, the total area of ​​the shared pixel openings of the third sub-pixel sp3 is larger than the total area of ​​the shared pixel openings of the first sub-pixel sp1, and larger than the total area of ​​the shared pixel openings of the second sub-pixel sp2. For example, the third sub-pixel sp3 can emit blue light, the first sub-pixel sp1 can emit green light, and the second sub-pixel sp2 can emit red light.

[0262] It should be noted that, in a shared pixel unit, the number of shared sub-pixels of the same color may be one or more.

[0263] In some embodiments, in an anti-privacy pixel unit, for multiple anti-privacy sub-pixels of the same color, the shapes and sizes of the anti-privacy sub-pixels can be the same or different. For example, the shapes and sizes of the anti-privacy sub-pixels can be the same.

[0264] In some embodiments, in a shared pixel unit, for multiple shared sub-pixels of the same color, the shapes and sizes of the shared sub-pixels may be the same or different. For example, the shapes and sizes of the shared sub-pixels may be the same.

[0265] In some embodiments, in an anti-privacy pixel unit, the total area A1 of the privacy pixel openings of multiple privacy sub-pixels of the same color is less than the total area A2 of the pixel openings of the shared sub-pixels of the same color in a corresponding shared pixel unit. Exemplarily, A1 / A2 is greater than or equal to 0.5 and less than or equal to 1, for example, A1 / A2 is equal to 4 / 6, or A1 / A2 is equal to 4 / 7.

[0266] In some embodiments, continuing to refer to Figure 21, in a combination including a single anti-peeping pixel unit and a single shared pixel unit, the projections of multiple anti-peeping sub-pixels emitting light of the same color on the substrate have a maximum coverage width m3 in the second direction Y, and the projections of shared sub-pixels corresponding to the multiple anti-peeping sub-pixels on the substrate have a maximum coverage width m4 in the second direction Y, and m4 is less than or equal to m3.

[0267] 2 , in some embodiments, in a combination including a single privacy protection pixel unit and a single shared pixel unit, a minimum spacing distance between the first sub-pixel sp1 and the second sub-pixel sp2 in the second direction Y is n4. A minimum spacing distance between the plurality of fourth sub-pixels sp1′ and the plurality of fifth sub-pixels sp2′ in the second direction Y is n3, where n4 is greater than or equal to n3.

[0268] It should be noted that the embodiments in FIG. 2 and FIG. 21 are merely schematic illustrations of possible arrangements of shared pixel units and privacy-preventing pixel units, and do not constitute a limitation to the present disclosure.

[0269] FIG. 22 shows a partial cross-sectional schematic diagram of the display panel according to some embodiments of the present disclosure, taken along line BB′ in FIG. 21 .

[0270] For example, in some embodiments of the present disclosure, referring to FIG22 , the pixel defining layer PDL may be made of a black material or a transparent material. The encapsulation layer 3 may be a thin film encapsulation, such as a three-layer or multi-layer structure of inorganic / organic / inorganic. The touch layer 5 may be composed of one or more layers of metal grids. The touch layer 5 includes a plurality of metal traces. Among them, at least a portion of the plurality of metal traces is reused as a third sub-light-shielding layer 203. The third sub-light-shielding layer 203 defines a plurality of third opening areas 213, wherein the orthographic projection of the third opening area 213 on the substrate substrate at least partially overlaps with the orthographic projection of the corresponding lens structure 7 on the substrate substrate.

[0271] For example, the projection shape of at least a portion of the third light-shielding layer 203 on the planes in the first direction X and the third direction Z can be a rectangle or a trapezoid. The third direction Z can be a direction perpendicular to the substrate or a light-emitting direction.

[0272] For example, the maximum width of the orthographic projection of the privacy protection pixel opening 32 on the substrate along the first direction X is a first width d1, the maximum width of the orthographic projection of the lens structure 7 on the substrate along the first direction X is a second width d2, and the ratio of the first width d1 to the second width d2 is less than or equal to 0.6. For example, the first width d1 is less than or equal to 6 microns, and the second width d2 is between 6 microns and 40 microns, including but not limited to these values. For example, the first width d1 is 6 microns, and the second width d2 is 11 microns.

[0273] By designing a small luminous area and a relatively large lens structure in the anti-privacy sub-pixel area, the viewing angle of the anti-privacy area can be reduced, which helps improve the anti-privacy effect. At the same time, the display brightness of the anti-privacy area can be increased, which helps improve the overall display effect of the display panel.

[0274] Continuing with FIG. 22 , an orthographic projection of at least a portion of the third sub-light-shielding portion 2031 onto the substrate has a fourth width d4 along the first direction. The ratio of the fourth width d4 to the second width d2 is between 0.2 and 0.8, for example, approximately 0.5. The fourth width d4 is between 3 microns and 20 microns, inclusive, but not limited thereto. For example, the fourth width d4 is 3 microns, and the second width d2 is 11 microns.

[0275] Exemplarily, the third sub-light-shielding layer 203 has a third thickness h3. The ratio of the third thickness h3 to the fourth thickness h4 is greater than or equal to 0.005 and less than or equal to 0.5. For example, the third thickness h3 is between 0.1 microns and 3 microns. The fourth thickness h4 is between 2 microns and 20 microns, for example, 8 microns to 20 microns, and the above ranges may include endpoints. For example, the third thickness h3 is 0.3 microns and the fourth thickness h4 is 8 microns. By making the third sub-light-shielding layer 203 thinner, the flatness of the film layer can be increased, which facilitates the formation of the lens structure above the light-shielding layer.

[0276] The lens structure 7 can be a hemispherical or spherical cap structure. For example, the lens structure 7 has a fifth thickness h5 along the third direction Z, where h5 is equal to 5 microns. The lens structure is formed using a high refractive index material. For example, the refractive index of the material in the lens structure 7 is between 1.5 and 1.8, including endpoint values, but not limited to these. The material surrounding the lens structure 7 is a low refractive index material. Exemplarily, the display panel may further include a fourth covering layer 8, an optical adhesive layer 9, a cover plate 10, and a hardened protective layer 11 located above the lens structure 7. These details will not be repeated here.

[0277] Continuing with FIG. 22 , the light-shielding layer may further include a second sub-light-shielding layer 202 between the touch layer 5 and the encapsulation layer 3. The second sub-light-shielding layer 202 includes a plurality of second sub-light-shielding portions 2021. The orthographic projections of the second sub-light-shielding portions 2021 onto the base substrate have a sixth width d6 along the first direction. The sixth width d6 is between 4 microns and 20 microns, including but not limited to these values. For example, the sixth width d6 is 8 microns.

[0278] For example, the projection shape of at least a portion of the second light-shielding sub-layer 202 on the plane where the first direction X and the third direction Z are located can be a rectangle or a trapezoid.

[0279] Exemplarily, the second sub-light-shielding layer 202 defines a plurality of second opening areas 212. The orthographic projection of the boundary of the privacy-prevention pixel opening 32 on the substrate is surrounded by the orthographic projection of the boundary of the corresponding second opening area 212 on the substrate. Alternatively, the orthographic projection of the privacy-prevention pixel opening 32 on the substrate at least partially overlaps with the orthographic projection of the second sub-light-shielding layer 202 on the substrate. For example, the distance between the orthographic projection of the boundary of the privacy-prevention pixel opening 32 on the substrate and the orthographic projection of the boundary of the corresponding second opening area 212 on the substrate is between -3 microns and 10 microns, for example, between 0 and 6 microns, and the above ranges may include endpoint values.

[0280] For example, the orthographic projection of the third sub-light-shielding layer 203 corresponding to the same privacy-prevention pixel opening on the substrate falls within the orthographic projection of the corresponding second sub-light-shielding layer 202 on the substrate. In other words, the third opening area 213 has a larger opening range than the second opening area 212. By optimizing the sizes of the third and second opening areas, light can be better controlled to be emitted toward the area where the lens structure is located, thereby improving display brightness in the privacy-prevention state.

[0281] For example, in some embodiments of the present disclosure, the second sub-light-shielding layer 202 has a second thickness h2, and the encapsulation layer 3 has a fourth thickness h4. The ratio of the second thickness h2 to the fourth thickness h4 is greater than or equal to 0.05 and less than or equal to 0.5. For example, the second thickness h2 is between 1 micron and 3 microns, and the fourth thickness h4 is between 2 microns and 20 microns, such as 8 microns to 20 microns. These ranges may include endpoints. For example, the second thickness h2 is 1.5 microns, and the fourth thickness h4 is 8 microns.

[0282] Through the combined design of the third sub-light-shielding layer 203 and the second sub-light-shielding layer 202, the light emitted by the anti-peeping sub-pixel is sequentially emitted from the second opening area 212 and the third opening area 213 toward the light-emitting side of the display panel, thereby enabling the display panel to achieve an anti-peeping mode through the anti-peeping sub-pixel.

[0283] For example, continuing to refer to Figure 22, the line connecting the first side of the light-emitting layer EL and the side of the adjacent third sub-light-shielding portion 2031 close to the light-emitting layer forms a first shading angle θ1 with the third direction Z, the line connecting the first side of the light-emitting layer EL and the side of the adjacent second sub-light-shielding portion 2021 close to the light-emitting layer forms a second shading angle θ2 with the third direction Z, the line connecting the second side of the light-emitting layer EL and the side of the adjacent second sub-light-shielding portion 2021 away from the light-emitting layer forms a third shading angle θ3 with the third direction Z, and the line connecting the first side of the light-emitting layer EL and the side of the adjacent third sub-light-shielding portion 2031 away from the light-emitting layer forms a fourth shading angle θ4 with the third direction z, wherein the first side of the light-emitting layer EL is the side away from the above-mentioned adjacent third sub-light-shielding layer 2031, and the second side of the light-emitting layer EL is the side close to the above-mentioned adjacent third sub-light-shielding layer 2031. Exemplarily, the first shielding angle θ1 is smaller than the second shielding angle θ2, the second shielding angle θ2 is smaller than the fourth shielding angle θ4, and the fourth shielding angle θ4 is smaller than the third shielding angle θ3.

[0284] By optimizing the shading angles of multiple shading layers, the viewing angle range of the anti-peeping area can be further reduced. For example, the viewing angle of the anti-peeping area can be reduced to about 25°. At the same time, the brightness at the positive viewing angle can be increased. For example, the brightness at the positive viewing angle can be increased by about 300%, thereby improving the display effect in the anti-peeping mode.

[0286] Optionally, embodiments of the present disclosure further provide a touch display device. Referring to FIG. 23 , the display device 200 may include the aforementioned display panel 100.

[0288] For example, referring to FIG. 24 , in an embodiment of the present disclosure, a method for manufacturing a display panel is also provided. The manufacturing method includes steps S01-S03:

[0289] In step S01, a plurality of sub-pixels are fabricated on a base substrate.

[0290] In step S02, a light shielding layer is formed on a side of the plurality of sub-pixels facing away from the base substrate, wherein the light shielding layer defines a plurality of opening areas, wherein the orthographic projections of the opening areas on the base substrate at least partially overlap with the orthographic projection of at least one privacy-preventing pixel opening on the base substrate.

[0291] In step S03, a lens structure is formed on the side of the light shielding layer away from the base substrate. The orthographic projection of at least one privacy-protection pixel opening on the base substrate falls within the orthographic projection of the lens structure on the base substrate. Furthermore, the orthographic projection of the lens structure on the base substrate at least partially overlaps with the orthographic projection of at least one opening area on the base substrate.
