Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and a display terminal. Background Technology

[0002] Consumers are becoming increasingly demanding in their expectations for the user experience of display products. For example, they are placing greater emphasis on protecting their personal privacy, which in turn leads to higher requirements for the privacy protection features of display products.

[0003] Display products achieve privacy features by incorporating a light-blocking layer. Simultaneously, to enable sensing functions, display products need to increase the light-transmitting area to improve light transmittance. However, the light-blocking layer obstructs light, affecting the transmittance of the light-transmitting area. Therefore, to meet transmittance requirements, the light-blocking layer needs to avoid the light-transmitting area, but this degrades privacy performance, manifesting as a biased view when viewed from the side.

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0026] According to the first aspect of this application, Figures 1 to 5 As shown, a display panel 1 is provided, including a first display area A1 and a second display area A2 disposed around the first display area A1. The display panel 1 includes a substrate 10, a driving circuit layer 20, a light-emitting layer 30, and a light-shielding layer 40. The light-emitting layer 30 is disposed on the side of the light-emitting layer 30 away from the substrate 10, and the light-emitting layer 30 includes a plurality of light-emitting units 31, including a privacy unit 310 and a non-privacy unit 320. The light-shielding layer 40 is disposed on the side of the light-emitting layer 30 away from the substrate 10, and the light-shielding layer 40 exposes the light-emitting units 31. The light-shielding layer 40 includes a first light-shielding part 41, a second light-shielding part 42, and a third light-shielding part 43. The second light-shielding part 42 and the third light-shielding part 43 are disposed on the same layer. The first light-shielding part 41 is located on the side of the third light-shielding part 43 away from the substrate 10, and the first light-shielding part 41 covers at least part of the third light-shielding part 43. The first light-shielding part 41 and the third light-shielding part 43 are located between two adjacent privacy units 310 along the first direction D1, and the second light-shielding part 42 is located between two adjacent non-privacy units 320 along the first direction D1. The distance s1 between the privacy unit 310 and the third light-shielding part 43 in the first direction D1 is smaller than the distance s2 between the non-privacy unit 320 and the second light-shielding part 42 in the first direction D1. The first light-shielding part 41 includes a first sub-light-shielding part 411 located in the first display area A1 and a second sub-light-shielding part 412 located in the second display area A2. The length s3 of the first sub-light-shielding part 411 in the second direction D2 is smaller than the length s4 of the second sub-light-shielding part 412 in the second direction D2. The second direction D2 intersects the first direction D1, and both the second direction D2 and the first direction D1 are perpendicular to the thickness direction of the display panel 1.

[0027] like Figure 1 As shown, the display panel 1 includes a display area AA and a non-display area NA disposed around the periphery of the display area AA. The display area AA can be provided with multiple sub-pixels, which can include a first sub-pixel, a second sub-pixel, and a third sub-pixel of different emitting colors. The first, second, and third sub-pixels can be red, green, and blue sub-pixels respectively, thereby achieving color display. The display area AA is provided with a pixel driving circuit, which drives the sub-pixels for display. The non-display area NA can be provided with a gate driving circuit, etc., which provides driving signals to the sub-pixels.

[0028] like Figure 1 As shown, the display area AA includes a first display area A1 and a second display area A2. Both the first display area A1 and the second display area A2 can display images.

[0029] In some embodiments, such as Figure 2 and Figure 3As shown, the sub-pixels of the first display area A1 and the second display area A2 are arranged in the same way, so that the display effects of the first display area A1 and the second display area A2 are similar.

[0030] In some embodiments, the first display area A1 may correspond to an IR (Infrared) aperture area, meaning the sensor may be positioned corresponding to the first display area A1. Ambient light can pass through the first display area A1 and illuminate the sensor. The sensor can then perform sensing functions based on the received light intensity. For example, the sensor can adaptively adjust the screen brightness according to the ambient light level.

[0031] In some embodiments, the second display area A2 can be a display area AA other than the first display area A1. The display area of ​​the second display area A2 is larger than the display area of ​​the first display area A1. The second display area A2 may not correspond to the sensor setting.

[0032] In some embodiments, the substrate 10 can be a rigid material or a flexible material. The rigid material can be glass, quartz, or silicon. The flexible material can be one of polyimide (PI), polycarbonate (PC), polynorbornene (PNB), and polyethylene terephthalate (PET).

[0033] In some embodiments, the driving circuit layer 20 includes a plurality of thin-film transistors, capacitors, and signal lines arranged in an array; and the plurality of thin-film transistors, capacitors, and signal lines can be used to form a driving circuit for driving the display panel 1 to display, such as a gate driving circuit, a pixel driving circuit, etc.

[0034] The materials for thin-film transistors, capacitors, and signal lines can include metallic materials, such as any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or alloys thereof.

[0035] It should be noted that the display panel 1 also includes multiple insulating layers, which are disposed between two adjacent metal materials to achieve insulation between adjacent metal materials, etc.

[0036] In some embodiments, when the display panel 1 is an OLED panel, the light-emitting layer 30 may include a stacked anode, a light-emitting material layer, and a cathode. The anode provides holes, the cathode provides electrons, and the holes and electrons recombine in the light-emitting material layer to emit light.

[0037] In some embodiments, such as Figure 4 and Figure 5 As shown, the display panel 1 also includes a pixel definition layer 50, which has multiple pixel openings. The light-emitting unit 31 is configured to correspond to the pixel openings, with one pixel opening corresponding to one light-emitting unit 31.

[0038] like Figure 4 As shown, the light-emitting layer 30 includes a plurality of light-emitting units 31. Each light-emitting unit 31 corresponds to a sub-pixel. The light-emitting units 31 may include red light-emitting units 31, green light-emitting units 31, and blue light-emitting units 31, thereby realizing color display.

[0039] like Figure 2 and Figure 3 As shown, the plurality of light-emitting units 31 include a privacy unit 310 and a non-privacy unit 320. The privacy unit 310 can be used in a privacy display mode, and the non-privacy unit 320 can be used to implement a shared display mode. It should be noted that both the privacy unit 310 and the non-privacy unit 320 are light-emitting units 31, and the privacy unit 310 and the non-privacy unit 320 can be arranged in the same way. Through the spacing between the light-shielding layer 40 and the light-emitting unit 31 in the first direction D1, a portion of the light-emitting unit 31 forms a privacy unit 310, while another portion forms a non-privacy unit 320.

[0040] like Figures 2 to 5 As shown, the light-shielding layer 40 is disposed on the side of the light-emitting layer 30 away from the substrate 10, and the light-shielding layer 40 is located on the light-emitting side of the light-emitting layer 30. The light-shielding layer 40 can block light. For example, the material of the light-shielding layer 40 can be a black material, such as black matrix, but it is not limited to this.

[0041] In some embodiments, such as Figure 2 , Figure 3 and Figure 5 As shown, the third light-shielding part 43 and the second light-shielding part 42 are disposed on the same layer. The third light-shielding part 43 and the second light-shielding part 42 can be formed by the same patterning process.

[0042] like Figure 4 and Figure 5 As shown, the first light-shielding portion 41 is located on the side of the third light-shielding portion 43 away from the substrate 10. Other film layers may be disposed between the first light-shielding portion 41 and the third light-shielding portion 43. The first light-shielding portion 41 and the third light-shielding portion 43 at least partially overlap in the thickness direction of the display panel 1.

[0043] like Figure 2 As shown, the distance s1 between the privacy unit 310 and the third light-shielding part 43 in the first direction D1 refers to the distance between the edges of the privacy unit 310 and the third light-shielding part 43 that are close to each other in the first direction D1. The distance s2 between the non-privacy unit 320 and the second light-shielding part 42 in the first direction D1 refers to the distance between the edges of the non-privacy unit 320 and the second light-shielding part 42 that are close to each other in the first direction D1.

[0044] Because the distance s1 between the privacy unit 310 and the third light-shielding part 43 in the first direction D1 is smaller than the distance s2 between the non-privacy unit 320 and the second light-shielding part 42 in the first direction D1, when the privacy unit 310 emits light, the distance s1 between the privacy unit 310 and the third light-shielding part 43 in the first direction D1 is smaller, and the third light-shielding part 43 can block the light from the privacy unit 310 at a wide viewing angle, thereby preventing others from observing the display screen from the side, thus realizing the privacy display mode. When the non-privacy unit 320 emits light, the distance s2 between the non-privacy unit 320 and the second light-shielding part 42 in the first direction D1 is larger, and it will not block the light from the non-privacy unit 320 at a wide viewing angle, thus allowing the display screen to be observed from a wide viewing angle, thereby realizing the shared display mode.

[0045] It should be understood that in privacy display mode, only privacy unit 310 can be illuminated. In shared display mode, both privacy unit 310 and non-privacy unit 320 can be illuminated simultaneously, or only non-privacy unit 320 can be illuminated.

[0046] In order to achieve the privacy display mode, the first light-shielding part 41 needs to block the wide-viewing-angle light around the privacy unit 310. This will cause the light around the light-transmitting pattern 20a to be blocked by the first light-shielding part 41, thus reducing the light transmittance of the display panel 1.

[0047] In response to this, in the embodiments of this application, such as Figure 2 and Figure 3 As shown, by setting the length s3 of the first sub-light-shielding part 411 in the second direction D2 to be smaller than the length s4 of the second sub-light-shielding part 412 in the second direction D2, the light-shielding layers 40 of the first display area A1 and the second display area A2 are differentiated. In the first display area A1, since the length s3 of the first sub-light-shielding part 411 in the second direction D2 is smaller, the light transmittance of the first display area A1 can be improved. At the same time, in the second display area A2, the length s4 of the second sub-light-shielding part 412 in the second direction D2 is larger, which can improve the privacy protection performance.

[0048] In some embodiments, such as Figure 4 and Figure 5 As shown, the display panel 1 also includes an encapsulation layer 60, which is disposed on the side of the light-emitting layer 30 away from the substrate 10. The encapsulation layer 60 can be formed by alternatingly stacked one or more organic encapsulation layers 62 and one or more inorganic encapsulation layers 61. For example, the organic encapsulation layer 62 can be a single layer or multiple layers formed of any one of polyethylene terephthalate, polyimide, polycarbonate, epoxy resin, polyethylene, and polyacrylate. The inorganic encapsulation layer 61 can be a single layer or multiple layers of metal oxide or metal nitride, such as silicon nitride, aluminum oxide, silicon oxide, etc.

[0049] In some embodiments, such as Figures 2 to 5 As shown, the display panel 1 also includes a touch electrode layer 70, which can be disposed between the encapsulation layer 60 and the light-shielding layer 40, and can be used to realize touch function.

[0050] In some embodiments, such as Figure 4 and Figure 5 As shown, the display panel 1 also includes a first insulating layer 81 disposed on the touch electrode layer 70 near the substrate 10 and a second insulating layer 82 disposed on the touch electrode layer 70 away from the substrate 10.

[0051] In some embodiments, such as Figure 4 and Figure 5 As shown, the display panel 1 also includes a third insulating layer 83 and a fourth insulating layer 84 disposed between the first light-shielding part 41 and the second light-shielding part 42.

[0052] In some embodiments, such as Figure 4 and Figure 5 As shown, the display panel 1 also includes a fifth insulating layer 85 disposed in the first light-shielding portion 41 away from the substrate 10.

[0053] The first insulating layer 81, the second insulating layer 82, the third insulating layer 83, the fourth insulating layer 84, and the fifth insulating layer 85 can be inorganic or organic layers. For example, the inorganic layer can be a single or multiple layers of metal oxides or metal nitrides, such as silicon nitride, alumina, or silicon oxide. The organic layer can be a single or multiple layers formed from any one of polyethylene terephthalate, polyimide, polycarbonate, epoxy resin, polyethylene, and polyacrylate.

[0054] Optionally, such as Figure 2 and Figure 3 As shown, the multiple privacy units 310 include a first light-emitting unit 311, a second light-emitting unit 312, and a third light-emitting unit 313 with different light-emitting colors. The first light-emitting unit 311 and the second light-emitting unit 312 are arranged alternately in a first column along the second direction D2, and the third light-emitting unit 313 is arranged in a second column along the second direction D2. The first column and the second column are arranged along the first direction D1. The first light-blocking part 41 extends along the second direction D2 and is located between adjacent first and second columns. In the second direction D2, both ends of the first light-blocking part 41 extend beyond the edge of the adjacent privacy unit 310.

[0055] In some embodiments, one privacy unit 310 corresponds to one sub-pixel. Multiple privacy units 310 may include a first light-emitting unit 311, a second light-emitting unit 312, and a third light-emitting unit 313. The first light-emitting unit 311 may be a red light-emitting unit 31, the second light-emitting unit 312 may be a green light-emitting unit 31, and the third light-emitting unit 313 may be a blue light-emitting unit 31.

[0056] In some embodiments, one non-peeping unit 320 corresponds to one sub-pixel. Multiple non-peeping units 320 may include a fourth light-emitting unit 321, a fifth light-emitting unit 322, and a sixth light-emitting unit 323. The fourth light-emitting unit 321 may be a red light-emitting unit 31, the fifth light-emitting unit 322 may be a green light-emitting unit 31, and the sixth light-emitting unit 323 may be a blue light-emitting unit 31.

[0057] It should be noted that, Figure 2 and Figure 3 The same cross-sectional pattern represents the same luminous unit 31 with the same luminous color.

[0058] In some embodiments, such as Figure 2 and Figure 3 As shown, the first light-shielding part 41, the second light-shielding part 42 and the third light-shielding part 43 all extend along the second direction D2. That is to say, the long sides of the first light-shielding part 41, the second light-shielding part 42 and the third light-shielding part 43 all extend along the second direction D2, and the short sides of the first light-shielding part 41, the second light-shielding part 42 and the third light-shielding part 43 all extend along the first direction D1.

[0059] like Figure 2 and Figure 3 As shown, the first light-emitting unit 311 and the second light-emitting unit 312 are disposed on the left side of the first light-shielding part 41, and the third light-emitting unit 313 is disposed on the right side of the first light-shielding part 41. On the left side of the first light-shielding part 41, the first light-emitting unit 311 and the second light-emitting unit 312 are arranged along the second direction D2 to form a first column of light-emitting units 31; on the right side of the first light-shielding part 41, the third light-emitting unit 313 is arranged along the second direction D2 to form a second column of light-emitting units 31.

[0060] In the second direction D2, such as Figure 2 and Figure 3 As shown, both ends of the first light-shielding portion 41 extend beyond the edges of the adjacent privacy units 310. This means that the lower end of the first light-shielding portion 41 extends beyond the lower edges of the adjacent non-privacy units 320 on both sides. The upper end of the first light-shielding portion 41 extends beyond the upper edges of the adjacent non-privacy units 320 on both sides. With this arrangement, the light-shielding portion 41 can effectively block light from the side view of the adjacent privacy units 310 on both sides, thus improving privacy performance.

[0061] Optionally, the first light-emitting unit 311, the second light-emitting unit 312, and the third light-emitting unit 313 all emit different colors, such as in the second direction D2. Figure 2 and Figure 3 As shown, the length s5 of the second sub-shading portion 412 extending beyond the adjacent first light-emitting unit 311 is greater than the length s8 of the first sub-shading portion 411 extending beyond the adjacent first light-emitting unit 311; and / or, in the second direction D2, the length s6 of the second sub-shading portion 412 extending beyond the adjacent second light-emitting unit 312 is greater than the length s9 of the first sub-shading portion 411 extending beyond the adjacent second light-emitting unit 312; and / or, in the second direction D2, the length s7 of the second sub-shading portion 412 extending beyond the adjacent third light-emitting unit 313 is greater than the length s10 of the first sub-shading portion 411 extending beyond the adjacent third light-emitting unit 313.

[0062] In some embodiments, the first light-emitting unit 311 can be a red light-emitting unit 31, and the light emitted by the first light-emitting unit 311 is red. The second light-emitting unit 312 can be a green light-emitting unit 31, and the light emitted by the second light-emitting unit 312 is green. The third light-emitting unit 313 can be a blue light-emitting unit 31, and the light emitted by the third light-emitting unit 313 is blue.

[0063] In some embodiments, such as Figure 2 and Figure 3 As shown, in the second direction D2, the length s5 of the second sub-shading portion 412 extending beyond the adjacent first light-emitting unit 311 is greater than the length s8 of the first sub-shading portion 411 extending beyond the adjacent first light-emitting unit 311. That is to say, the length of the second sub-shading portion 412 extending beyond the edge of the adjacent first light-emitting unit 311 is longer, and the length of the first sub-shading portion 411 extending beyond the edge of the adjacent first light-emitting unit 311 is shorter.

[0064] Since the first display area A1 needs to consider not only privacy protection but also light transmittance, the first sub-shielding part 411 can be shorter than the second sub-shielding part 412, and the length of the first sub-shielding part 411 extending beyond the adjacent light-emitting unit 31 is shorter. This reduces the obstruction of ambient light by the first sub-shielding part 411, making the light transmittance of the first display area A1 greater than that of the second display area A2, thus meeting the light-sensing requirements of the sensor.

[0065] In the second display area A2, no sensor is installed. Therefore, the second sub-shielding part 412 can be longer than the first sub-shielding part 411, and the second sub-shielding part 412 extends further beyond the adjacent light-emitting unit 31, thereby improving the privacy protection effect. Since the second sub-shielding part 412 is longer in the second direction D2, it can also block more light from the right side of the adjacent light-emitting unit 31, thereby reducing the asymmetry of light from the left and right sides of the adjacent light-emitting unit 31 in the side viewing angle, and thus improving white angle dependence (WAD).

[0066] In some embodiments, such as Figure 2 and Figure 3 As shown, in the second direction D2, the length s5 of the second sub-shielding portion 412 extending beyond the adjacent first light-emitting unit 311 is greater than the length s8 of the first sub-shielding portion 411 extending beyond the adjacent first light-emitting unit 311. This increases the light transmittance of the first display area A1 and improves the color shift in the second display area A2 caused by the asymmetry of light on both sides of the first light-emitting unit 311 at the side viewing angle. For example, when the first light-emitting unit 311 is a red light-emitting unit 31, by making the length of the second sub-shielding portion 412 extending beyond the adjacent red light-emitting unit 31 in the second direction D2 longer, more red light can be blocked, thereby improving the color shift problem of the white screen appearing reddish at the side viewing angle.

[0067] In some embodiments, such as Figure 2 and Figure 3 As shown, in the second direction D2, the length s6 of the second sub-shielding portion 412 extending beyond the adjacent second light-emitting unit 312 is greater than the length s9 of the first sub-shielding portion 411 extending beyond the adjacent second light-emitting unit 312. This increases the light transmittance of the first display area A1 and improves the color shift in the second display area A2 caused by the asymmetry of light on both sides of the second light-emitting unit 312 at the side viewing angle. For example, when the second light-emitting unit 312 is a green light-emitting unit 31, by making the length of the second sub-shielding portion 412 extending beyond the adjacent green light-emitting unit 31 in the second direction D2 longer, more green light can be blocked, thereby improving the color shift problem of the white screen appearing greenish at the side viewing angle.

[0068] In some embodiments, such as Figure 2 and Figure 3As shown, in the second direction D2, the length s7 of the second sub-shielding portion 412 extending beyond the adjacent third light-emitting unit 313 is greater than the length s10 of the first sub-shielding portion 411 extending beyond the adjacent third light-emitting unit 313. This increases the light transmittance of the first display area A1 and improves the color shift in the second display area A2 caused by the asymmetry of light on both sides of the third light-emitting unit 313 at the side viewing angle. For example, when the third light-emitting unit 313 is a blue light-emitting unit 31, by making the length of the second sub-shielding portion 412 extending beyond the blue light-emitting unit 31 in the second direction D2 longer, more blue light can be blocked, thereby improving the color shift problem of the white screen appearing bluish at the side viewing angle.

[0069] Optionally, such as Figure 3 As shown, in the second direction D2, the length s5 of the second sub-shading part 412 extending beyond the adjacent first light-emitting unit 311 is greater than the length s6 of the second sub-shading part 412 extending beyond the adjacent second light-emitting unit 312, and the length s5 of the second sub-shading part 412 extending beyond the adjacent first light-emitting unit 311 is greater than the length s7 of the second sub-shading part 412 extending beyond the adjacent third light-emitting unit 313.

[0070] In some embodiments, the first light-emitting unit 311 can be a red light-emitting unit 31, the second light-emitting unit 312 can be a green light-emitting unit 31, and the third light-emitting unit 313 can be a blue light-emitting unit 31. Since the human eye is more sensitive to and less accepting of reddish, greenish, and bluish tints in a white image, the length s5 of the second sub-shading portion 412 extending beyond the adjacent first light-emitting unit 311 can be greater than the length s6 of the second sub-shading portion 412 extending beyond the adjacent second light-emitting unit 312, and the length s5 of the second sub-shading portion 412 extending beyond the adjacent first light-emitting unit 311 can be greater than the length s7 of the second sub-shading portion 412 extending beyond the adjacent third light-emitting unit 313.

[0071] This means that, in the second direction D2, the second sub-shielding portion 412 extends the longest beyond the adjacent red light-emitting unit 31, exceeding the length of the second sub-shielding portion 412 extending beyond the adjacent green light-emitting unit 31, and the length of the second sub-shielding portion 412 extending beyond the adjacent red light-emitting unit 31 exceeds the length of the second sub-shielding portion 412 extending beyond the adjacent blue light-emitting unit 31. With this arrangement, the reddish color shift problem of the white image in the second display area A2 under side viewing angles can be better improved.

[0072] In some embodiments, such as Figure 2As shown, in the second direction D2, the length s8 of the first sub-shielding portion 411 extending beyond the adjacent first light-emitting unit 311 is greater than the length s9 of the first sub-shielding portion 411 extending beyond the adjacent second light-emitting unit 312, and the length s8 of the first sub-shielding portion 411 extending beyond the adjacent first light-emitting unit 311 is greater than the length s10 of the first sub-shielding portion 411 extending beyond the adjacent third light-emitting unit 313. With the above arrangement, the reddish color shift problem of the white image in the first display area A1 under side viewing angle can be better improved.

[0073] Optionally, such as Figure 2 and Figure 3 As shown, the privacy unit 310 and the non-privacy unit 320 are arranged alternately along the first direction D1, and the privacy unit 310 and the non-privacy unit 320 are arranged alternately along the second direction D2; wherein, in the second direction D2, the second sub-light-shielding part 412 is located near the edge of the non-privacy unit 320 and is spaced apart from the non-privacy unit 320.

[0074] like Figure 2 and Figure 3 As shown, the privacy unit 310 and the non-privacy unit 320 are arranged alternately along the first direction D1. That is to say, the privacy unit 310 and the non-privacy unit 320 are alternately arranged along the first direction D1. For example, a non-privacy unit 320 is provided between two adjacent privacy units 310 in the first direction D1, and a privacy unit 310 is provided between two adjacent non-privacy units 320 in the first direction D1.

[0075] like Figure 2 and Figure 3 As shown, the privacy unit 310 and the non-privacy unit 320 are arranged alternately along the second direction D2. That is to say, in the second direction D2, the privacy unit 310 and the non-privacy unit 320 are alternately arranged. For example, a non-privacy unit 320 is provided between two adjacent privacy units 310 in the second direction D2, and a privacy unit 310 is provided between two adjacent non-privacy units 320 in the second direction D2.

[0076] It should be noted that the alternation period can be set as needed, that is, at least one privacy screen unit 310 and at least one non-privacy screen unit 320 alternate. For example, the alternation period can be two, that is, one privacy screen unit 310 and one non-privacy screen unit 320 alternate. The alternation period can be greater than two, such as three, four, five, etc., that is, multiple privacy screen units 310 and multiple non-privacy screen units 320 alternate.

[0077] In some embodiments, such as Figure 2 and Figure 3As shown, the privacy pixel includes three light-emitting units 31 with different light-emitting colors, and the non-privacy pixel also includes three light-emitting units 31 with different light-emitting colors. The privacy pixel and the non-privacy pixel are arranged alternately along the first direction D1 and the second direction D2.

[0078] In some embodiments, such as Figure 3 As shown, in the second direction D2, the second sub-light-shielding portion 412 is positioned near the edge of the non-privacy unit 320, spaced apart from it. This means that in the second direction D2, the second sub-light-shielding portion 412 does not extend to be flush with the edge of the non-privacy unit 320, nor does it extend to overlap with the non-privacy unit 320 in the first direction D1. This arrangement prevents the length s4 of the second sub-light-shielding portion 412 in the second direction D2 from becoming too long, thus avoiding any impact on the shared display mode effect of the non-privacy unit 320.

[0079] Optionally, such as Figures 2 to 5 As shown, the display panel 1 also includes a touch electrode layer 70 disposed between the light-emitting layer 30 and the light-shielding layer 40. The touch electrode layer 70 includes a first electrode line 71 extending along a first direction D1 and a second electrode line 72 extending along a second direction D2. The first electrode line 71 and the second electrode line 72 are intersected and connected to form a grid structure, which is located between two adjacent light-emitting units 31. In the second direction D2, the second sub-light-shielding part 412 extends beyond the first electrode line 71 located between the adjacent first light-emitting unit 311 and the adjacent non-peeping unit 320. In the second direction D2, the first sub-light-shielding part 411 is disposed on the side of the first electrode line 71 between the adjacent first light-emitting unit 311 and the adjacent non-peeping unit 320 that is close to the first light-emitting unit 311.

[0080] like Figure 2 and Figure 3 As shown, in the second direction D2, the first electrode line 71 is disposed between two adjacent light-emitting units 31. A portion of the first electrode line 71 is disposed between two adjacent privacy units 310, a portion of the first electrode line 71 is disposed between two adjacent non-privacy units 320, and a portion of the first electrode line 71 is disposed between adjacent privacy units 310 and non-privacy units 320.

[0081] like Figure 2 and Figure 3 As shown, in the first direction D1, the second electrode line 72 is disposed between two adjacent light-emitting units 31. A portion of the second electrode line 72 is disposed between two adjacent privacy units 310, a portion of the second electrode line 72 is disposed between two adjacent non-privacy units 320, and a portion of the second electrode line 72 is disposed between adjacent privacy units 310 and non-privacy units 320.

[0082] In some embodiments, such as Figure 3 As shown, in the second direction D2, the second sub-shielding portion 412 extends beyond the first electrode line 71 located between the first light-emitting unit 311 and the adjacent non-peeping unit 320. This means that in the second direction D2, the second sub-shielding portion 412 can extend beyond the first electrode line 71 between the peeping unit 310 and the non-peeping unit 320; that is, the length s5 of the second sub-shielding portion 412 extending beyond the first light-emitting unit 311 is greater than the distance between the lower adjacent first electrode line 71 and the first light-emitting unit 311.

[0083] In some embodiments, such as Figure 2 As shown, in the second direction D2, the first sub-light-shielding portion 411 is disposed on the side of the first electrode line 71 between the first light-emitting unit 311 and the adjacent non-peeping unit 320, closer to the first light-emitting unit 311. This means that in the second direction D2, the first sub-light-shielding portion 411 does not extend beyond the first electrode line 71 between the peeping unit 310 and the non-peeping unit 320; that is, the length s8 of the first sub-light-shielding portion 411 extending beyond the first light-emitting unit 311 is less than the distance between the lower adjacent first electrode line 71 and the first light-emitting unit 311.

[0084] Optionally, such as Figure 4 and Figure 5 As shown, the display panel 1 also includes a driving circuit layer 20 disposed between the substrate 10 and the light-emitting layer 30. The driving circuit layer 20 has a plurality of light-transmitting patterns 20a. The area of ​​the light-transmitting pattern 20a covered by the first sub-shielding part 411 is smaller than the area of ​​the light-transmitting pattern 20a covered by the second sub-shielding part 412.

[0085] In some embodiments, the driving circuit layer 20 includes a plurality of driving circuit patterns, and a light-transmitting pattern 20a is formed in the clearance area of ​​the driving circuit patterns. The driving circuit layer 20 includes circuit structures such as thin-film transistors, capacitors, and signal lines, which form the driving circuit patterns. The light-transmitting pattern 20a refers to a pattern that allows light to pass through. When light shines on the driving circuit layer 20 along the thickness direction of the display panel 1, part of the light is blocked by the driving circuit patterns, while light can pass through at the light-transmitting pattern 20a; that is, the area where light passes through forms the light-transmitting pattern 20a.

[0086] Since no circuit structure is present in the light-transmitting pattern 20a, it does not block light, meaning light can pass through. In contrast, in areas where thin-film transistors, capacitors, or signal lines are present, light is blocked by the metal material, preventing its passage. The light-transmitting pattern 20a increases the light transmittance of the display panel 1, allowing the sensor beneath the display panel 1 to receive ambient light and thus achieve sensing functionality.

[0087] In some embodiments, such as Figure 2 and Figure 3 As shown, the area of ​​the light-transmitting pattern 20a covered by the first sub-light-shielding part 411 is smaller than the area of ​​the light-transmitting pattern 20a covered by the second sub-light-shielding part 412. This arrangement reduces the area of ​​the light-transmitting pattern 20a covered by the first sub-light-shielding part 411, thereby increasing the light transmittance of the first display area A1. Since the second display area A2 does not have a sensor, the area of ​​the light-transmitting pattern 20a covered by the second sub-light-shielding part 412 can be larger, improving the privacy protection effect of the second display area A2.

[0088] In some embodiments, such as Figure 2 As shown, in the first direction D1, the first sub-shading part 411 exposes at least part of the light-transmitting pattern 20a, so that light from the side view angle in the first direction D1 can pass through the light-transmitting pattern 20a.

[0089] In some embodiments, such as Figure 2 As shown, in the second direction D2, the first sub-shading part 411 exposes at least part of the light-transmitting pattern 20a, so that light from the side view angle in the second direction D2 can pass through the light-transmitting pattern 20a.

[0090] In some embodiments, such as Figure 3 As shown, in the second direction D2, the second sub-shielding part 412 at least covers part of the light-transmitting pattern 20a, thereby improving the privacy protection effect of the second display area A2.

[0091] Optionally, such as Figure 2 As shown, the extension direction of the outline of the first sub-shading part 411 that is close to the light-transmitting pattern 20a is at least partially the same as the extension direction of the outline of the grid structure that is close to the light-transmitting pattern 20a.

[0092] In some embodiments, the outline of the first sub-shielding portion 411 near the edge of the light-transmitting pattern 20a in the second direction D2 can be parallel to the outline of the lower edge of the first electrode line 71, and the outline of the first sub-shielding portion 411 near the edge of the light-transmitting pattern 20a in the first direction D1 can be parallel to the outline of the right edge of the second electrode line 72. With this configuration, the first sub-shielding portion 411 can both block the first electrode line 71 and the second electrode line 72, and also allow the first sub-shielding portion 411 to avoid the light-transmitting pattern 20a to a greater extent, thereby increasing the amount of light that can be received by the sensor.

[0093] Optionally, such as Figure 2As shown, the first sub-shading part 411 is flush with the edge of the light-transmitting pattern 20a in the second direction D2, and is also flush with the edge of the first electrode line 71 near the light-transmitting pattern 20a; the first sub-shading part 411 is flush with the edge of the light-transmitting pattern 20a in the first direction D1, and is also flush with the edge of the second electrode line 72 near the light-transmitting pattern 20a.

[0094] In some embodiments, such as Figure 2 As shown, the edge of the first sub-shielding portion 411 near the light-transmitting pattern 20a in the second direction D2 is flush with the lower edge of the first electrode line 71, and the edge of the first sub-shielding portion 411 near the light-transmitting pattern 20a in the first direction D1 is flush with the right edge of the second electrode line 72. This allows the first sub-shielding portion 411 to at least partially block the first electrode line 71 and a portion of the second electrode line 72, reducing the reflection of ambient light by the touch electrode layer 70. Simultaneously, the large distance between the first sub-shielding portion 411 and the light-transmitting pattern 20a increases the amount of light that can be received by the sensor.

[0095] Optionally, such as Figure 2 and Figure 3 As shown, the extending direction of the outline of the third light-shielding portion 43, which is close to the light-transmitting pattern 20a, is at least partially the same as the extending direction of the outline of the light-transmitting pattern 20a, which is close to the third light-shielding portion 43. That is to say, the extending directions of the outlines of the edges of the third light-shielding portion 43 and the light-transmitting pattern 20a that are close to each other are at least partially the same. With this arrangement, the third light-shielding portion 43 can at least partially avoid the light-transmitting pattern 20a, thereby increasing the light transmittance of the first display area A1.

[0096] Optionally, such as Figure 2 As shown, the third light-shielding part 43 exposes at least part of the light-transmitting pattern 20a, the first sub-light-shielding part 411 exposes part of the third light-shielding part 43, and the second sub-light-shielding part 412 exposes the third light-shielding part 43 or covers the third light-shielding part 43.

[0097] In some embodiments, such as Figure 2 and Figure 3 As shown, the edge of the third light-shielding part 43 near the light-transmitting pattern 20a can extend beyond the lower edge of the first electrode and the right edge of the second electrode line 72, thereby reducing the risk of light leakage at a wide viewing angle.

[0098] In some embodiments, such as Figure 2 As shown, the second sub-shading part 412 covers the third shaded part 43, thereby making the light transmittance of the first display area A1 greater than that of the second display area A2, increasing the amount of light received by the sensor.

[0099] In some embodiments, Figure 6 This shows another enlarged structural diagram of the second display area A2. Figure 6 The embodiments and Figure 3 The difference in the embodiment lies in the second sub-shielding part 412. For example... Figure 6 As shown, the second sub-shielding part 412 exposes the third shielding part 43, thereby making the second sub-shielding part 412 further away from the light-transmitting pattern 20a relative to the third shielding part 43. This makes the light transmittance around the light-transmitting pattern 20a of the first display area A1 and the second display area A2 similar, reducing the difference in display effect between the first display area A1 and the second display area A2.

[0100] In some embodiments, such as Figure 2 , Figure 3 and Figure 6 As shown, in the second direction D2, the second light-shielding part 42 can be connected to the third light-shielding part 43, thereby further reducing the risk of light leakage at a wide viewing angle.

[0101] In other embodiments, in the second direction D2, the second light-shielding part 42 may be disconnected from the third light-shielding part 43, thereby reducing the obstruction of light near the light-transmitting pattern 20a by the second light-shielding part 42 and the third light-shielding part 43.

[0102] In other embodiments, such as Figure 2 As shown, in the second direction D2, a portion of the second light-shielding part 42 can be connected to the third light-shielding part 43 to further reduce the risk of light leakage at a large viewing angle; another portion of the second light-shielding part 42 can be disconnected from the third light-shielding part 43 to reduce the obstruction of light near the light-transmitting pattern 20a by the second light-shielding part 42 and the third light-shielding part 43.

[0103] Optionally, such as Figure 6 As shown, the second sub-shading part 412 exposes the third shading part 43. The extension direction of the outline of the second sub-shading part 412, which is close to the light-transmitting pattern 20a, is at least partially the same as the extension direction of the outline of the grid structure, which is close to the light-transmitting pattern 20a.

[0104] In some embodiments, such as Figure 6 As shown, the outline of the second sub-shielding part 412 near the edge of the light-transmitting pattern 20a in the second direction D2 can be parallel to the outline of the lower edge of the first electrode line 71, and the outline of the second sub-shielding part 412 near the edge of the light-transmitting pattern 20a in the first direction D1 can be parallel to the outline of the right edge of the second electrode line 72. With this arrangement, the second sub-shielding part 412 can both block the first electrode line 71 and the second electrode line 72, and also avoid the light-transmitting pattern 20a to a greater extent, thereby reducing the difference in light transmittance between the first display area A1 and the second display area A2, making the visual effects of the first display area A1 and the second display area A2 more similar.

[0105] Optionally, such as Figure 6As shown, the second sub-shading part 412 is flush with the edge of the light-transmitting pattern 20a in the second direction D2, and is also flush with the edge of the first electrode line 71 near the light-transmitting pattern 20a; the second sub-shading part 412 is flush with the edge of the light-transmitting pattern 20a in the first direction D1, and is also flush with the edge of the second electrode line 72 near the light-transmitting pattern 20a.

[0106] In some embodiments, such as Figure 6 As shown, the edge of the second sub-shielding portion 412 near the light-transmitting pattern 20a in the second direction D2 can be flush with the lower edge of the first electrode line 71, and the edge of the second sub-shielding portion 412 near the light-transmitting pattern 20a in the first direction D1 can be flush with the right edge of the second electrode line 72. This allows the second sub-shielding portion 412 to at least partially block the first electrode line 71 and a portion of the second electrode line 72, reducing the reflection of ambient light by the touch electrode layer 70. Simultaneously, the second sub-shielding portion 412 avoids the light-transmitting pattern 20a to a greater extent, thereby reducing the difference in light transmittance between the first display area A1 and the second display area A2, making the visual effects of the first display area A1 and the second display area A2 more similar.

[0107] Optionally, such as Figures 2 to 5 As shown, the light-shielding layer 40 also includes a fourth light-shielding part 44 and a fifth light-shielding part 45 located between the privacy unit 310 and the non-privacy unit 320 adjacent along the first direction D1. The fourth light-shielding part 44 is disposed in the same layer as the second light-shielding part 42, and the fifth light-shielding part 45 is disposed in the same layer as the first light-shielding part 41. The fifth light-shielding part 45 and the fourth light-shielding part 44 at least partially overlap. Among them, two fourth light-shielding parts 44 adjacent along the second direction D2 are connected and disposed, and two fifth light-shielding parts 45 adjacent along the second direction D2 are connected and disposed. The light-transmitting pattern 20a is located between two fourth light-shielding parts 44 adjacent along the first direction D1.

[0108] In some embodiments, the fourth light-shielding portion 44 is located between the privacy unit 310 and the non-privacy unit 320 adjacent to each other along the second direction D2. In other words, the left side of the fourth light-shielding portion 44 is adjacent to the privacy unit 310, and the right side of the fourth light-shielding portion 44 is adjacent to the non-privacy unit 320. The distance between the fourth light-shielding portion 44 and the privacy unit 310 in the first direction D1 is smaller than the distance between the fourth light-shielding portion 44 and the non-privacy unit 320 in the first direction D1, thereby enabling the privacy unit 310 to achieve a privacy display mode, and the non-privacy unit 320 to achieve a shared display mode.

[0109] In some embodiments, the maximum width of the fourth light-shielding portion 44 and the fifth light-shielding portion 45 in the first direction D1 may be the same.

[0110] In some embodiments, the fourth light-shielding portion 44 and the fifth light-shielding portion 45 may completely overlap or partially overlap.

[0111] In some embodiments, the fourth light-shielding portion 44 and the fifth light-shielding portion 45 can be flush with the edge of the privacy unit 310 in the first direction D1, thereby improving the privacy effect.
