[0002] With the development of display technology, some display products need to have anti-peeping functions.

[0047] The display panel and display device provided in the embodiments of the present application can be used in, but not limited to, vehicle-mounted display products.

[0048] In one embodiment, a display panel is provided. Figure 1 as well as Figure 2 The display panel includes a pixel layer and a light shielding layer. The pixel layer includes a plurality of pixel units 100. According to the number of pixel units 100 per unit area, the pixel density (PPI) can be determined.

[0049] Each pixel unit 100 includes a plurality of sub-pixels 110 of different colors. It can be understood that each of the plurality of sub-pixels 110 of different colors is a sub-pixel 110 for emitting light of different colors. For example, each pixel unit 100 may include a red sub-pixel R for emitting red light, a green sub-pixel G for emitting green light, and a blue sub-pixel B for emitting blue light.

[0050] Each sub-pixel 110 includes an anti-peeping sub-pixel 111 and a sharing sub-pixel 112 .

[0051] The light shielding layer is located on the light-emitting side of the pixel layer. As an example, the display panel may further include an encapsulation layer 300 covering the pixel layer. The light shielding layer may be located on the encapsulation layer 300.

[0052] The light shielding layer includes a light shielding unit 200. The light shielding unit 200 may be, but is not limited to, a black matrix (BM) or the like.

[0053] The shading unit 200 is at least located on two opposite sides of the anti-peeping sub-pixel 111, thereby suppressing light pollution in a specific direction, thereby realizing anti-peeping of the anti-peeping sub-pixel 111 in a specific direction. Specifically, the specific form of the shading unit 200 can be set according to the anti-peeping requirements of the display panel.

[0054] At the same time, since the same sub-pixel 110 includes both the anti-peeping sub-pixel 111 and the sharing sub-pixel 112 , at least a portion of the light shielding unit 200 is located between the anti-peeping sub-pixel 111 and the sharing sub-pixel 112 .

[0055] The same shading unit 200 located between the anti-peeping sub-pixel 111 and the sharing sub-pixel 112 has a first distance d1 from the anti-peeping sub-pixel 111 and a second distance d2 from the sharing sub-pixel 112, and the second distance d2 is greater than the first distance d1. That is, the same shading unit 200 located between the anti-peeping sub-pixel 111 and the sharing sub-pixel 112 is close to the anti-peeping sub-pixel 111 and away from the sharing sub-pixel 112, thereby preventing the light emission of the sharing sub-pixel 112 from being affected by the setting of the shading unit 200.

[0056] In this embodiment, each sub-pixel 110 includes an anti-peeping sub-pixel 111 and a sharing sub-pixel 112, so that the same sub-pixel 110 can realize both an anti-peeping display function and a sharing display function, thereby effectively improving the pixel density. At the same time, the same shading unit 200 located between the anti-peeping sub-pixel 111 and the sharing sub-pixel 112 is close to the anti-peeping sub-pixel 111 and away from the sharing sub-pixel 112, thereby preventing the light emission of the sharing sub-pixel 112 from being affected by the setting of the shading unit 200, thereby effectively ensuring a normal display effect.

[0057] In one embodiment, the first distance d1 is less than 2 μm, and the second distance d2 is greater than 6 μm. In this case, the light shielding unit 200 can effectively adjust the light emission direction of the anti-peeping sub-pixel 111, and can effectively prevent the light shielding unit 200 from affecting the normal light emission of the adjacent shared sub-pixel 112.

[0058] Optionally, the first distance d1 is 1μm-2μm. The smaller the first distance d1 is, the better the adjustment effect of the shading unit 200 on the light emitting direction of the anti-peeping sub-pixel 111 is, and at the same time, the higher the precision requirement for the process is. In the actual process, there are process errors in the actual position and size of the shading unit 200. Therefore, setting the first distance d1 to 1μm-2μm can achieve controllable precision on the one hand, and prevent the shading unit 200 from shielding the anti-peeping sub-pixel 111 and affecting the display brightness of the anti-peeping sub-pixel 111 on the other hand.

[0059] In one embodiment, the display panel includes at least two light shielding layers stacked and spaced apart from each other. An optical adhesive layer 400 or the like may be disposed between adjacent light shielding layers.

[0060] The more light shielding layers there are, the better the light leakage prevention effect is, and the better the effect of adjusting the light emission direction of the anti-peeping sub-pixel 111 is.

[0061] Specifically, for example, the display panel may include two or three light shielding layers, which can achieve a good light shielding effect, improve the manufacturing efficiency of the display panel, and make the display panel thinner and lighter.

[0062] In one embodiment, see Figure 2 , the pixel layer includes a plurality of pixel groups 100 a arranged along a first direction D1.

[0063] The pixel groups 100a are pixel columns or pixel rows. Each pixel group 100a includes a plurality of pixel units 100 arranged along a second direction D2. The second direction D2 intersects with the first direction D1.

[0064] When the pixel groups 100a are pixel columns, each pixel group 100a includes a column of pixel units 100. Then the first direction D1 is a row direction, and the second direction D2 is a column direction.

[0065] When the pixel group 100a is a pixel row, each pixel group 100a includes a row of pixel units 100. Then the first direction D1 is a column direction, and the second direction D2 is a row direction.

[0066] Each pixel group 100 a includes two pixel sub-groups 100 b arranged along the first direction D1 , and each sub-pixel 110 in the same pixel unit 100 is respectively located in the two pixel sub-groups 100 b of the same pixel group 100 a .

[0067] As an example, each pixel unit 100 includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B. Among the two pixel sub-groups 100b in the same pixel group 100a, one pixel sub-group 100b may be provided with a blue sub-pixel B, and the other pixel sub-group 100b may be provided with a red sub-pixel R and a green sub-pixel G. And the red sub-pixels R and the green sub-pixels G in the same pixel unit 100 may be arranged along the second direction D2.

[0068] Each pixel subgroup 100b includes an anti-peeping pixel group 100c and a sharing pixel group 100d arranged along the first direction D1. Each anti-peeping pixel group 100c includes a plurality of anti-peeping sub-pixels 111 arranged along the second direction D2, and each sharing pixel group 100d includes a plurality of sharing sub-pixels 112 arranged along the second direction D2. At this time, the same sub-pixel 110 can be divided along the first direction D1 to form the anti-peeping sub-pixels 111 and the sharing sub-pixels 112.

[0069] For any of the two pixel sub-groups 100b of the same pixel group 100a, a privacy-prevention pixel group 100c is disposed on a side close to the other pixel, and a sharing pixel group 100d is disposed on a side away from the other pixel.

[0070] For example, see Figure 2 In the two pixel sub-groups 100b of the same pixel group 100a, the pixel sub-group 100b (pixel column) on the left is provided with an anti-peeping sub-pixel 111 on the right and a sharing sub-pixel 112 on the left; the pixel sub-group 100b (pixel column) on the right is provided with an anti-peeping sub-pixel 111 on the left and a sharing sub-pixel 112 on the right.

[0071] At this time, there is no light shielding unit 200 between adjacent pixel groups 100 a , so that a smaller distance between the two can be set, thereby improving the pixel density.

[0072] In one embodiment, please refer to Figure 2 The light shielding unit 200 is strip-shaped and extends along the second direction D2. The light shielding unit 200 includes a first light shielding unit 210 and a second light shielding unit 220.

[0073] The first light shielding unit 210 is located between two adjacent anti-peeping pixel groups 100c of the same pixel group 100a. The second light shielding unit 220 is located between the anti-peeping pixel group 100c and the shared pixel group 100d of the same pixel subgroup 100b. The same pixel group 100a corresponds to three light shielding units 200, and the three light shielding units 200 include one first light shielding unit 210 and two second light shielding units 220.

[0074] At this time, by extending the strip-shaped light shielding unit 200 along the second direction D2, the anti-peeping sub-pixel 111 can be prevented from leaking light in the first direction D1, thereby achieving the anti-peeping function in the first direction D1.

[0075] Specifically, when the pixel group 100a is a pixel column and the first direction D1 is a row direction, the horizontal anti-peeping function can be effectively realized. When the pixel group 100a is a pixel row and the first direction D1 is a column direction, the vertical anti-peeping function can be effectively realized.

[0076] In one embodiment, see Figure 3 The light shielding unit 200 is mesh-shaped and extends along the second direction D2. The anti-peeping sub-pixels 111 in the same pixel group 100a are located in the mesh of the same light shielding unit 200.

[0077] At this time, the light shielding units 200 and the pixel groups 100a can be arranged in a one-to-one correspondence. Each pixel group 100a has a corresponding light shielding unit 200.

[0078] The anti-peeping sub-pixel 111 is arranged in the mesh of the light shielding unit 200 , so that the light of the anti-peeping sub-pixel 111 can be shielded in both the first direction D1 and the second direction D2 , thereby realizing an all-round anti-peeping function.

[0079] As an example, see Figure 4 , at least part of the anti-peeping sub-pixel 111 includes at least two sub-sub-pixels 1111 arranged along the second direction D2.

[0080] When the anti-peeping sub-pixel 111 extends along the second direction D2 and has a longer length in the second direction D2, more light shielding layers need to be provided to ensure that the anti-peeping sub-pixel 111 does not leak light.

[0081] Therefore, the anti-peeping sub-pixel 111 includes at least two sub-pixels 1111 arranged along the second direction D2, which can further divide the anti-peeping sub-pixel 111, thereby reducing the length of each sub-pixel 1111 in the second direction D2, thereby reducing the number of light shielding layers.

[0082] In one embodiment, see Figure 5 , the light shielding unit 200 has a groove on one side in the first direction D1. In the same sub-pixel 110, the anti-peeping sub-pixel 111 is located in the groove, the sharing sub-pixel 112 is located on one side of the anti-peeping sub-pixel 111 in the first direction D1, and the sharing sub-pixel 112 and the anti-peeping sub-pixel 111 are located on the same side of the light shielding unit 200.

[0083] Optionally, at least part of the privacy protection sub-pixel 111 includes at least two sub-pixels 1111 arranged along the second direction D2. In this case, two grooves may be formed in the light shielding unit 200 corresponding to the same privacy protection sub-pixel 111 to accommodate the two sub-pixels 1111.

[0084] In this embodiment, the anti-peeping sub-pixel 111 is exposed on one side in the first direction D1, while the other sides are surrounded and covered by the shading unit 200, thereby realizing a three-sided anti-peeping function, so that the display panel can be applied to, but not limited to, notebooks, etc.

[0085] The light shielding unit 200 has a groove for accommodating the anti-peeping sub-pixel 111 on one side in the first direction D1, and divides the sub-pixel 110 into the anti-peeping sub-pixel 111 and the sharing sub-pixel 112 in the first direction D1. The non-peeping direction of the sub-pixel 110 is consistent with the dividing direction. Therefore, in the first direction D1, the sharing sub-pixel 112 only needs to maintain a larger distance (the second distance d2) from the light shielding unit 200 located on one side thereof, thereby effectively improving the pixel density.

[0086] In one embodiment, see Figure 6 or Figure 7 The pixel layer includes anti-peeping pixel groups 100c and sharing pixel groups 100d alternately arranged along a first direction D1.

[0087] Each anti-peeping pixel group 100 c includes a plurality of anti-peeping sub-pixels 111 arranged along a second direction D2 , and each sharing pixel group 100 d includes a plurality of sharing sub-pixels 112 arranged along a second direction D2 , where the second direction D2 intersects with the first direction D1 .

[0088] As an example, the first direction D1 may be a column direction, and the second direction D2 may be a row direction. Each anti-peeping pixel group 100c may include a row of anti-peeping sub-pixels 111. Each sharing pixel group 100d may include a row of sharing sub-pixels 112.

[0089] The light shielding unit 200 extends along the second direction D2 and has a plurality of grooves arranged along the second direction D2 on one side of the first direction D1. The plurality of privacy sub-pixels 111 in the same privacy pixel group 100 c are located in different grooves of the same light shielding unit 200 .

[0090] The luminous colors of the privacy protection sub-pixels 111 in different grooves of the same light shielding unit 200 may be the same or different.

[0091] In the present embodiment, the light shielding unit 200 extends along the second direction D2, thereby effectively reducing the difficulty of manufacturing the light shielding unit 200.

[0092] In one embodiment, see Figure 6 , the pixel layer may include a plurality of pixel groups 100a arranged along the first direction D1. The pixel groups 100a may be, for example, pixel rows. Each pixel group 100a includes a plurality of pixel units 100 arranged along the second direction D2.

[0093] Each pixel group 100 a includes two pixel sub-groups 100 b arranged along the first direction D1 , and each sub-pixel 110 in the same pixel unit 100 is respectively located in the two pixel sub-groups 100 b of the same pixel group 100 a .

[0094] For example, each pixel unit 100 includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B. Among the two pixel sub-groups 100b in the same pixel group 100a, one pixel sub-group 100b may be provided with a blue sub-pixel B, and the other pixel sub-group 100b may be provided with a red sub-pixel R and a green sub-pixel G. And the red sub-pixels R and the green sub-pixels G in the same pixel unit 100 may be arranged along the second direction D2.

[0095] Each pixel subgroup 100b includes an anti-peeping pixel group 100c and a sharing pixel group 100d arranged along the first direction D1, and the anti-peeping pixel group 100c in each pixel subgroup 100b is located on the same side of the sharing pixel group 100d, so that the anti-peeping pixel groups 100c and the sharing pixel groups 100d of the pixel layer are alternately distributed.

[0096] In the present embodiment, both sides of the shared sub-pixel 112 in the second direction D2 are not blocked, so that the color shift in the second direction D2 can be effectively reduced.

[0097] In one embodiment, see Figure 7 , the pixel layer may include a plurality of pixel groups 100a arranged along a first direction D1. The pixel group 100a may be, for example, a pixel row. Each pixel group 100a includes a plurality of pixel units 100 arranged along a second direction D2. Each sub-pixel 110 of each pixel unit 100 in each pixel group 100a is arranged along the second direction D2. For example, each pixel unit 100 includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B arranged along the second direction D2.

[0098] Meanwhile, the shared sub-pixels 112 extend along the first direction D1 .

[0099] In this embodiment, both sides of the shared sub-pixel 112 in the second direction D2 are not blocked, and the color deviation in the second direction D2 can also be effectively reduced. At the same time, the length of the shared sub-pixel 112 in the first direction D1 is relatively large, so that the color deviation effect in the first direction D1 caused by the portion of the shared sub-pixel 112 close to the light shielding unit 200 can also be effectively reduced. Therefore, this embodiment can make the display panel have a smaller color deviation in all directions.

[0100] In one embodiment, see Figure 1 The display panel further includes a first electrode 500 and a pixel definition layer 600. The first electrode 500 may be, for example, an anode. Of course, the first electrode 500 may also be a cathode.

[0101] The pixel definition layer 600 covers the first electrode 500 , and has a pixel opening exposing the first electrode 500 therein.

[0102] The pixel opening includes an anti-peeping opening and a sharing opening that are arranged at intervals. The anti-peeping sub-pixel 111 and the sharing sub-pixel 112 of the same sub-pixel 110 are respectively located in the anti-peeping opening and the sharing opening, and the anti-peeping opening and the sharing opening corresponding to the same sub-pixel 110 expose the same first electrode 500. At this time, the anti-peeping sub-pixel 111 and the sharing sub-pixel 112 of the same sub-pixel 110 can share the first electrode 500. At the same time, the anti-peeping sub-pixel 111 and the sharing sub-pixel 112 of the same sub-pixel 110 can be evaporated through the same fine mask (FMM) opening, thereby simplifying the process.

[0103] Optionally, the same anti-peeping sub-pixel 111 includes at least two sub-sub-pixels 1111. The anti-peeping opening includes at least two sub-openings arranged at intervals. That is, the pixel definition layer 600 is provided with at least two sub-openings corresponding to the same anti-peeping sub-pixel 111. The sub-sub-pixels 1111 are located in the sub-openings, and the sub-sub-pixels 1111 are arranged in a one-to-one correspondence with the sub-openings, so that each sub-sub-pixel 1111 is separated by the pixel definition layer 600.

[0104] In one embodiment, the display panel further includes a switch circuit, wherein the switch circuit includes a first switch and a second switch.

[0105] As an example, see Figure 1 The display panel may further include a substrate. The substrate may include a substrate (not shown), a circuit layer (not shown) formed on the substrate, and a planarization layer 700 covering the circuit layer. The first electrode 500 and the pixel definition layer 600 may be formed on the planarization layer 700.

[0106] The substrate may be a rigid substrate or a flexible substrate. The circuit layer may include multiple wiring layers and a dielectric layer isolating the wiring layers. A switch circuit may be formed in the circuit layer.

[0107] The switch circuit can be set in a one-to-one correspondence with the sub-pixel 110. Different sub-pixels 110 are connected to different switch circuits, and the anti-peeping sub-pixel 111 is connected to the first switch, and the sharing sub-pixel 112 is connected to the second switch. At this time, the anti-peeping sub-pixel 111 and the anti-peeping sub-pixel 111 of the same sub-pixel 110 are respectively switched by different switches, so that the same sub-pixel 110 can have multiple states.

[0108] The multiple states may include at least a first working state, a second working state, a third working state, and a closed state. The first working state may be that the anti-peeping sub-pixel 111 is turned on and the sharing sub-pixel 112 is turned off; the second working state may be that the sharing sub-pixel 112 is turned on and the anti-peeping sub-pixel 111 is turned off; the third working state may be that both the anti-peeping sub-pixel 111 and the sharing sub-pixel 112 are turned on; and the closed state may be that both the anti-peeping sub-pixel 111 and the sharing sub-pixel 112 are turned off.

[0109] When the display panel operates in the anti-peeping mode, each sub-pixel 110 may be in a first working state. When the display panel operates in the first sharing mode, each sub-pixel 110 may be in a second working state. When the display panel operates in the second sharing mode, each sub-pixel 110 may be in a third working state. When the display panel is not operating, each sub-pixel 110 may be in an off state.

[0110] Optionally, the display panel may further include a driving circuit. The first switch connected to the same sub-pixel 110 is connected to the same driving circuit as the second switch. The driving circuit may be a circuit such as 8T1C, 9T1C, or 10T1C.

[0111] In this embodiment, each sub-pixel 110 includes an anti-peeping sub-pixel 111 and a sharing sub-pixel 112, and the anti-peeping sub-pixel 111 and the sharing sub-pixel 112 are respectively connected to different switches. Therefore, the display panel can have two sharing modes (a first sharing mode and a second sharing mode) to meet different brightness requirements.

[0112] Based on the same inventive concept, an embodiment of the present application further provides a display device (not shown), which includes the display panel in the above embodiment.

[0113] It can be understood that the display device in the embodiments of the present application can be an OLED display device, a QLED display device, electronic paper, a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, a wearable device, an Internet of Things device, or any other product or component with a display function, and the embodiments disclosed in the present application are not limited to this.
