[0014] In either of the two pixel subgroups of the same pixel group, the privacy pixel group is set on the side closer to the other, while the sharing pixel group is set on the side farther away from the other.

[0015] In one embodiment, the light-shielding unit is strip-shaped and extends along the second direction, and the light-shielding unit includes:

[0016] The first light-shielding unit is located between two adjacent privacy pixel groups within the same pixel group;

[0021] Optionally, at least a portion of the privacy-protecting sub-pixels includes at least two sub-pixels arranged along the second direction.

[0022] In one embodiment, the pixel layer includes privacy pixel groups and sharing pixel groups arranged alternately along the first direction. Each privacy pixel group includes a plurality of privacy sub-pixels arranged along a second direction, and each sharing pixel group includes a plurality of sharing sub-pixels arranged along the second direction, which intersects with the first direction.

[0023] The light-shielding unit extends along the second direction and has a plurality of grooves arranged along the second direction on one side of the first direction. The plurality of privacy sub-pixels in the same privacy pixel group are located in different grooves of the same light-shielding unit.

[0024] Optionally, the pixel layer includes a plurality of pixel groups arranged along a first direction, each pixel group includes a plurality of pixel units arranged along a second direction, each sub-pixel of each pixel unit in each pixel group is arranged along the second direction, and the shared sub-pixels extend along the first direction.

Simultaneously, the light-shielding unit located between the privacy-protecting sub-pixel and the sharing sub-pixel is closer to the privacy-protecting sub-pixel and farther away from the sharing sub-pixel, preventing the light-shielding unit from affecting the light emission of the sharing sub-pixel and thus effectively ensuring normal display performance.

[0047] The display panel and display device provided in this application embodiment can be applied to, but are not limited to, in vehicle display products.

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

[0049] Each pixel unit 100 includes multiple sub-pixels 110 of different colors. It can be understood that each of these multiple sub-pixels 110 is a sub-pixel 110 used to emit 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 subpixel 110 includes a privacy pixel 111 and a sharing 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 also 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 light-shielding units 200. Light-shielding units 200 may be, but are not limited to, black matrix (BM), etc.

[0053] The light-shielding unit 200 is located at least on both sides of the privacy pixel 111 that are opposite to each other, thereby suppressing light pollution in a specific direction and thus achieving privacy protection for the privacy pixel 111 in a specific direction. Specifically, the form of the light-shielding unit 200 can be set according to the privacy requirements of the display panel.

[0054] Meanwhile, since the same sub-pixel 110 includes both the privacy pixel 111 and the sharing pixel 112, at least part of the light-blocking unit 200 is located between the privacy pixel 111 and the sharing pixel 112.

[0055] The same light-blocking unit 200 located between the privacy pixel 111 and the sharing pixel 112 is at a first distance d1 from the privacy pixel 111 and at a second distance d2 from the sharing pixel 112, where the second distance d2 is greater than the first distance d1. That is, the same light-blocking unit 200 located between the privacy pixel 111 and the sharing pixel 112 is closer to the privacy pixel 111 and farther from the sharing pixel 112, thereby preventing the setting of the light-blocking unit 200 from affecting the light emission of the sharing pixel 112.

[0056] In this embodiment, each sub-pixel 110 includes a privacy-protecting sub-pixel 111 and a sharing sub-pixel 112, so that the same sub-pixel 110 can realize both privacy-protecting display function and sharing display function, thereby effectively improving pixel density. At the same time, the same light-shielding unit 200 located between the privacy-protecting sub-pixel 111 and the sharing sub-pixel 112 is closer to the privacy-protecting sub-pixel 111 and farther away from the sharing sub-pixel 112, thereby preventing the setting of the light-shielding unit 200 from affecting the light emission of the sharing sub-pixel 112, thus effectively ensuring normal display effect.

[0057] In one embodiment, the first distance d1 is less than 2μm, and the second distance d2 is greater than 6μm. In this case, the light emission direction of the privacy pixel 111 can be effectively adjusted by the light-shielding unit 200, and the normal light emission of its neighboring sharing pixel 112 can be effectively prevented from being affected by the light-shielding unit 200.

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

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

[0060] The more layers of light-blocking layer there are, the better the light leakage prevention effect and the better the adjustment effect on the light emission direction of the privacy pixel 111.

[0061] Specifically, for example, the display panel can be configured to include two or three light-shielding layers. This not only provides good light-shielding effect but also improves the manufacturing efficiency of the display panel and makes it thinner and lighter.

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

[0063] Pixel group 100a is either a pixel column or a pixel row. Each pixel group 100a includes multiple pixel units 100 arranged along the second direction D2. The second direction D2 intersects the first direction D1.

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

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

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

[0067] As an example, each pixel unit 100 includes a red subpixel R, a green subpixel G, and a blue subpixel B. Within the two pixel subgroups 100b of the same pixel group 100a, one pixel subgroup 100b can be configured with the blue subpixel B, while the other pixel subgroup 100b can be configured with the red subpixel R and the green subpixel G. Furthermore, the red subpixel R and the green subpixel G within the same pixel unit 100 can be arranged along the second direction D2.

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

[0069] In the same pixel group 100a, each of the two pixel subgroups 100b has a privacy pixel group 100c on the side closer to the other, and a sharing pixel group 100d on the side farther from the other.

[0070] For example, please see Figure 2 In the two pixel subgroups 100b of the same pixel group 100a, the left pixel subgroup 100b (pixel column) has a privacy pixel 111 on the right and a sharing pixel 112 on the left; the right pixel subgroup 100b (pixel column) has a privacy pixel 111 on the left and a sharing pixel 112 on the right.

[0071] At this time, there is no light-blocking unit 200 between adjacent pixel groups 100a, so that the distance between them can be set to be small, thereby increasing the pixel density.

[0072] In one embodiment, please continue reading 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-blocking unit 210 is located between two adjacent privacy pixel groups 100c in the same pixel group 100a. The second light-blocking unit 220 is located between the privacy pixel group 100c and the sharing pixel group 100d in the same pixel subgroup 100b. The same pixel group 100a corresponds to three light-blocking units 200, which include one first light-blocking unit 210 and two second light-blocking units 220.

[0074] At this time, by extending the strip-shaped light-blocking unit 200 along the second direction D2, light leakage of the privacy pixel 111 in the first direction D1 can be prevented, thereby realizing the privacy function in the first direction D1.

[0075] Specifically, when pixel group 100a is a pixel column and the first direction D1 is a row direction, horizontal privacy protection can be effectively achieved. When pixel group 100a is a pixel row and the first direction D1 is a column direction, vertical privacy protection can be effectively achieved.

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

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

[0078] By placing the privacy pixel 111 within the mesh of the light-blocking unit 200, the light from the privacy pixel 111 can be blocked in both the first direction D1 and the second direction D2, thereby achieving an all-around privacy function.

[0079] For example, please refer to Figure 4 At least some of the privacy-protecting sub-pixels 111 include at least two sub-pixels 1111 arranged along the second direction D2.

[0080] When the privacy pixel 111 extends along the second direction D2 and has a large length in the second direction D2, more light-blocking layers are required to ensure that the privacy pixel 111 does not leak light.

[0081] Therefore, by setting the privacy pixel 111 to include at least two sub-pixels 1111 arranged along the second direction D2, the privacy pixel 111 can be further divided, 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 privacy pixel 111 is located in the groove, and the sharing pixel 112 is located on one side of the privacy pixel 111 in the first direction D1, and the sharing pixel 112 and the privacy pixel 111 are located on the same side of the light-shielding unit 200.

[0083] Optionally, at least some of the privacy-protecting sub-pixels 111 include at least two sub-pixels 1111 arranged along the second direction D2. In this case, within the light-shielding unit 200, two grooves can be formed corresponding to the same privacy-protecting sub-pixel 111 to accommodate the two sub-pixels 1111.

[0084] In this embodiment, the privacy pixel 111 is exposed on one side in the first direction D1, while the other sides are surrounded and covered by the light-shielding unit 200, thereby achieving a three-sided privacy function, which allows the display panel to be used in, but not limited to, laptops.

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

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

[0087] Each privacy pixel group 100c includes a plurality of privacy 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, the second direction D2 intersecting the first direction D1.

[0088] As an example, the first direction D1 can be a column direction, and the second direction D2 can be a row direction. Each privacy pixel group 100c can include a row of privacy sub-pixels 111. Each sharing pixel group 100d can 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 in the first direction D1. A plurality of privacy pixels 111 within the same privacy pixel group 100c are located in different grooves of the same light-shielding unit 200.

[0090] The light emission colors of the privacy pixels 111 in different grooves of the same light-shielding unit 200 can be the same or different.

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

[0092] In one embodiment, see Figure 6 The pixel layer can be configured to include multiple pixel groups 100a arranged along a first direction D1. Pixel group 100a can be, for example, a pixel row. Each pixel group 100a includes multiple pixel units 100 arranged along a second direction D2.

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

[0094] For example, each pixel unit 100 includes a red subpixel R, a green subpixel G, and a blue subpixel B. Within the same pixel group 100a, two pixel subgroups 100b can each have a blue subpixel B, while the other subgroup can have a red subpixel R and a green subpixel G. Furthermore, the red subpixel R and green subpixel G within the same pixel unit 100 can be arranged along the second direction D2.

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

[0096] In this embodiment, the shared sub-pixel 112 is unobstructed on both sides in the second direction D2, thereby effectively reducing color shift in the second direction D2.

[0097] In one embodiment, see Figure 7 The pixel layer can be configured to include multiple pixel groups 100a arranged along a first direction D1. Pixel group 100a can be, for example, a pixel row. Each pixel group 100a includes multiple 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] At the same time, the shared sub-pixel 112 extends along the first direction D1.

[0099] In this embodiment, the sharing pixel 112 is unobstructed on both sides in the second direction D2, which effectively reduces color shift in the second direction D2. Simultaneously, the sharing pixel 112 has a relatively large length in the first direction D1, thus effectively reducing the color shift effect in the first direction D1 caused by the portion of the sharing pixel 112 near the light-shielding unit 200. Therefore, this embodiment allows the display panel to have minimal color shift in all directions.

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

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

[0102] The pixel aperture includes a privacy aperture and a sharing aperture spaced apart. The privacy sub-pixel 111 and the sharing sub-pixel 112 of the same sub-pixel 110 are located within the privacy aperture and the sharing aperture, respectively, and the privacy aperture and the sharing aperture corresponding to the same sub-pixel 110 expose the same first electrode 500. In this case, the privacy sub-pixel 111 and the sharing sub-pixel 112 of the same sub-pixel 110 can share the first electrode 500. Simultaneously, the privacy sub-pixel 111 and the sharing sub-pixel 112 of the same sub-pixel 110 can be vapor-deposited through the same fine mask (FMM) opening, thereby simplifying the manufacturing process.

[0103] Optionally, the same privacy-protecting sub-pixel 111 includes at least two sub-pixels 1111. The privacy-protecting opening includes at least two spaced-apart sub-openings. That is, the pixel definition layer 600 provides at least two sub-openings corresponding to the same privacy-protecting sub-pixel 111. The sub-pixels 1111 are located within the sub-openings, and the sub-pixels 1111 and the sub-openings are configured in a one-to-one correspondence, thereby separating each sub-pixel 1111 by the pixel definition layer 600.

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

[0105] For example, please refer to Figure 1 The display panel may also include a substrate. The substrate may include a base (not shown), a circuit layer (not shown) formed on the base, 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 can be a rigid substrate or a flexible substrate. The circuit layer can include multiple wiring layers and dielectric layers that isolate the wiring layers. Switching circuits can be formed in the circuit layer.

[0107] The switching circuits can be configured one-to-one with sub-pixels 110. Different sub-pixels 110 are connected to different switching circuits, with the privacy pixel 111 connected to the first switch and the privacy pixel 112 connected to the second switch. In this case, the privacy pixels 111 of the same sub-pixel 110 are controlled by different switches, thus allowing the same sub-pixel 110 to have multiple states.

[0108] The multiple states can include at least a first working state, a second working state, a third working state, and a closed state. Specifically, the first working state can be that the privacy pixel 111 is on and the sharing pixel 112 is off; the second working state can be that the sharing pixel 112 is on and the privacy pixel 111 is off; the third working state can be that both the privacy pixel 111 and the sharing pixel 112 are on; and the closed state can be that both the privacy pixel 111 and the sharing pixel 112 are off.

[0109] When the display panel is operating in privacy mode, each sub-pixel 110 can be in a first operating state. When the display panel is operating in a first sharing mode, each sub-pixel 110 can be in a second operating state. When the display panel is operating in a second sharing mode, each sub-pixel 110 can be in a third operating state. When the display panel is not operating, each sub-pixel 110 can be in a closed state.

[0110] Optionally, the display panel may also include a driving circuit. A 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 an 8T1C, 9T1C, 10T1C, or similar circuit.

[0111] In this embodiment, each sub-pixel 110 includes a privacy-protecting sub-pixel 111 and a sharing sub-pixel 112, and the privacy-protecting 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.
