Description

Technical Field

[0001] This application relates to the field of privacy display technology, specifically to a display device and a display driving method. Background Technology

[0002] To minimize interference between the passenger-side in-vehicle display and the driver, the display uses a split-screen design to display different content. A privacy screen is added to the light-emitting side of the display panel. While this privacy screen limits the viewing angle and prevents privacy viewing, conventional displays struggle to simultaneously display shared in-vehicle information and separate content for the driver and passenger. This makes it difficult for conventional displays to meet the multi-view content display requirements in privacy mode. Summary of the Invention

[0009] Furthermore, the first light-shielding layer includes a first opening and a second opening. In the direction from the substrate to the pixel layer, the first opening is located above the first privacy pixel, and the second opening is located above the second privacy pixel. From a viewing angle along the thickness direction of the display device, a portion of one of the light-shielding strips located on the first side of the first privacy pixel overlaps with a portion of the first opening, while the other light-shielding strip located on the second side of the first privacy pixel does not overlap with the first opening; One of the light-shielding strips located on the first side of the second privacy pixel does not overlap with the second opening, while a portion of the other light-shielding strip located on the second side of the second privacy pixel overlaps with a portion of the second opening.

[0010] Furthermore, the display device also includes: First pixel definition layer; A second pixel definition layer, the second pixel definition layer includes a plurality of second pixel definition parts, the plurality of second pixel definition parts being spaced apart in a first direction of the display device; Specifically, from a viewing angle along the thickness direction of the display device, a portion of the light-shielding strip located on the first side of the first privacy pixel protrudes from a second pixel definition portion near an edge of the first privacy pixel; an edge of another light-shielding strip located on the second side of the first privacy pixel is recessed within the orthographic projection of another second pixel definition portion; an edge of a light-shielding strip located on the first side of the second privacy pixel is recessed within the orthographic projection of a second pixel definition portion; and a portion of another light-shielding strip located on the second side of the second privacy pixel protrudes from another second pixel definition portion near an edge of the second privacy pixel.

[0011] Furthermore, the display device includes a plurality of pixel repeating units, each pixel repeating unit including a first pixel group, a second pixel group, and a third pixel group.

[0022] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings. The technical solutions described below are for illustrative purposes only and should not be construed as limiting the scope of protection of this application.

[0023] Furthermore, the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different technical features. The terms "multiple" and similar words indicate two or more unless otherwise expressly specified.

[0024] With the increasing intelligence of vehicles, in-vehicle displays are installed to display information. Current solutions use a split-screen approach to display different images, creating separate screens for the driver and passenger. While this split-screen display spatially differentiates content, the driver and passenger may still see each other's screens from the side, leading to interference. To mitigate this interference, conventional solutions add a privacy screen to the light-emitting side of the display. While this limits the viewing angle and prevents privacy viewing, it significantly obstructs light, resulting in severe brightness reduction. Furthermore, it makes it difficult to simultaneously display shared in-vehicle information and the independent display of the driver's and passenger's screens.

[0025] The first embodiment of this application provides a display device 10, see reference. Figure 1 The display device 10 includes a plurality of first privacy pixels P1, a plurality of second privacy pixels P2, and a plurality of display pixels P3. The plurality of first privacy pixels P1, the plurality of second privacy pixels P2, and the plurality of display pixels P3 are arranged in an array. The first privacy pixels P1 are used to provide a first display screen to the right viewing area in the privacy display mode. The second privacy pixels P2 are used to provide a second display screen to the left viewing area in the privacy display mode. The display pixels are used to provide a third display screen to the left viewing area and the right viewing area in the privacy display mode.

[0026] It is understood that in this embodiment, the display device 10 includes multiple first privacy pixels P1, multiple second privacy pixels P2, and multiple display pixels P3, arranged in an array. The first privacy pixels P1 are used to provide a first display screen to the right viewing area in the privacy display mode, the second privacy pixels P2 are used to provide a second display screen to the left viewing area in the privacy display mode, and the display pixels are used to provide a third display screen to the left and right viewing areas in the privacy display mode. This allows the first display screen to be exclusively displayed in the right viewing area, the second display screen to be exclusively displayed in the left viewing area, and the third display screen to be shared in both the left and right viewing areas. This enables the simultaneous display of a driver's exclusive screen, a passenger's exclusive screen, and a shared screen on the vehicle display device 10, thereby fulfilling the multi-content display requirements under multiple viewing angles in the privacy mode of the display device 10.

[0027] It should be noted that in this embodiment, one of the left and right viewing directions is the primary driver's view direction, and the other is the passenger's view direction. That is, when the left viewing direction is the primary driver's view direction, the right viewing direction is the passenger's view direction, and vice versa. In other words, the content of the first display screen in the left viewing direction and the content of the second display screen in the right viewing direction are determined by the positions of the primary and passenger's view directions. When the left viewing direction is the primary driver's view direction and the right viewing direction is the passenger's view direction, the first display screen displays information for the primary driver, and the second display screen displays information for the passenger. Similarly, when the left viewing direction is the passenger's view direction and the right viewing direction is the primary driver's view direction, the first display screen displays information for the passenger, and the second display screen displays information for the primary driver. In this embodiment, the example of the left viewing direction being the primary driver's view direction and the right viewing direction being the passenger's view direction is used for illustration.

[0028] It should be noted that the information displayed by the in-vehicle display device 10 includes driver display information, passenger display information, and shared display information. The driver display information can be the information data that the driver needs when driving the vehicle. The passenger display information can be the information data that the driver does not need to use while the vehicle is in motion, but which has a significant impact on the driver. The shared display information can be the regular display information, which has a smaller impact on the driver. Among them, the driver information includes navigation, vehicle speed, Advanced Driver Assistance Systems (ADAS) prompts, and vehicle status. The passenger information includes video, games, audio-visual entertainment, or application interfaces. The shared display information includes time, air conditioning, volume, vehicle status, system notifications, and basic user interface (UI).

[0029] In this embodiment, the display device 10 is an in-vehicle display device.

[0030] In this embodiment, the display pixel P3 is also used to provide a third display image to the area between the left and right viewing directions.

[0031] It is understandable that the left and right viewing directions can be the wide viewing angle display directions, and the area between the left and right viewing directions is the narrow viewing angle display direction. The narrow viewing angle is the viewing angle range of 0 to 45 degrees, and the wide viewing angle is the viewing angle range of more than 45 degrees.

[0032] In this embodiment, the display device 10 includes a shared display mode and a privacy display mode. In the shared display mode, the same graphic data is input to the first privacy pixel P1, the second privacy pixel P2, and the third privacy pixel. In the privacy display mode, first image data is input to the first privacy pixel P1, second graphic data is input to the second privacy pixel P2, and third graphic data is input to the display pixel P3.

[0033] It is understood that, in this embodiment, since the display device 10 is configured to include a shared display mode and a privacy display mode, in the shared display mode, the same graphic data is input to the first privacy pixel P1, the second privacy pixel P2, and the third privacy pixel. In the privacy display mode, first image data is input to the first privacy pixel P1, second graphic data is input to the second privacy pixel P2, and third graphic data is input to the display pixel P3. That is, in the shared display mode, the first privacy pixel P1, the second privacy pixel P2, and the display pixel P3 can jointly display the same display screen to improve the display brightness and resolution of the display device 10. In the privacy display mode, the first privacy pixel P1 and the second privacy pixel P2 display different screens to reduce crosstalk between the display screen provided by the first privacy pixel P1 and the display screen provided by the second privacy pixel P2.

[0034] It is understood that the above embodiments are merely illustrations of one display method of the privacy mode. In another embodiment, when implementing the privacy mode display, only the first privacy pixel P1 may provide the display screen, only the second privacy pixel P2 may provide the display screen, or the first privacy pixel P1 and the display pixel P3 may each provide two different display screens, or the second privacy pixel P2 and the display pixel P3 may each provide two different display screens, or the first privacy pixel P1 and the second privacy pixel P2 may each provide two different display screens. The specific display method of the display device 10 can be controlled by the control chip of the display device 10 to enable the display device 10 to implement multiple different display modes.

[0035] In this embodiment, reference Figure 1 , Figure 2The plurality of first privacy pixels P1 include a first sub-pixel P1a, a second sub-pixel P1b, and a third sub-pixel P1c. The first sub-pixel P1a emits red light, the second sub-pixel P1b emits green light, and the third sub-pixel P1c emits blue light. The plurality of second privacy pixels P2 include a fourth sub-pixel P2a, a fifth sub-pixel P2b, and a sixth sub-pixel P2c. The fourth sub-pixel P2a emits red light, the fifth sub-pixel P2b emits green light, and the sixth sub-pixel P2c emits blue light. The plurality of display pixels P3 include a seventh sub-pixel P3a, an eighth sub-pixel P3b, and a ninth sub-pixel P3c. The seventh sub-pixel P3a emits red light, the eighth sub-pixel P3b emits green light, and the ninth sub-pixel P3c emits blue light.

[0036] In this embodiment, reference Figure 3 , Figure 4 , Figure 5 , Figure 6 The display device 10 further includes a substrate 100, a pixel layer 200, a first light-shielding layer 300, and a second light-shielding layer 400; the pixel layer 200 is disposed on the substrate 100; the first light-shielding layer 300 is disposed on the side of the pixel layer 200 away from the substrate 100; the second light-shielding layer 400 is disposed on the side of the first light-shielding layer 300 away from the substrate 100, and the second light-shielding layer 400 includes a plurality of light-shielding strips 410, which are spaced apart in a first direction L of the display device 10; wherein, the first privacy pixel P1 is located between two adjacent light-shielding strips 410, the second privacy pixel P2 is located between two adjacent light-shielding strips 410, and the light-shielding strip 410 located on the first side of the first privacy pixel P1... The distance 'a' between the edge of the first privacy pixel P1 and the edge of the pixel opening 510 of the first privacy pixel P1 is less than the distance 'b' between the edge of the light-shielding strip 410 located on the second side of the first privacy pixel P1 and the edge of the pixel opening 510 of the first privacy pixel P1. The distance 'c' between the edge of the light-shielding strip 410 located on the first side of the second privacy pixel P2 and the edge of the pixel opening 510 of the second privacy pixel P2 is greater than the distance 'd' between the edge of the light-shielding strip 410 located on the second side of the second privacy pixel P2 and the edge of the pixel opening 510 of the second privacy pixel P2. The first side of the first privacy pixel P1 and the second side of the first privacy pixel P1 are opposite to each other, and the first side of the second privacy pixel P2 and the second side of the second privacy pixel P2 are opposite to each other.

[0037] It is understood that in this embodiment, multiple light-shielding strips 410 are arranged at intervals along the first direction L of the display device 10; wherein, the first privacy pixel P1 is located between two adjacent light-shielding strips 410, the second privacy pixel P2 is located between two adjacent light-shielding strips 410, and the distance 'a' between the edge of the light-shielding strip 410 on the first side of the first privacy pixel P1 and the edge of the pixel opening 510 of the first privacy pixel P1 is smaller than the distance 'a' between the edge of the light-shielding strip 410 on the second side of the first privacy pixel P1 and the edge of the pixel opening 510 of the first privacy pixel P1. The distance b between the edges of the opening 510 is greater than the distance c between the edge of the light-shielding strip 410 on the first side of the second privacy pixel P2 and the edge of the pixel opening 510 of the second privacy pixel P2. The first side and the second side of the first privacy pixel P1 are opposite to each other, and the first side and the second side of the second privacy pixel P2 are opposite to each other. That is, the light-shielding strip 410 is used to block the first privacy pixel P2. The light-blocking effects of the first and second sides of the first privacy pixel P1 and the second privacy pixel P2 are designed differently. Furthermore, the directions of these differentiating designs are opposite; that is, the first privacy pixel P1 is designed for privacy on the first side but not on the second side, and the second privacy pixel P2 is designed for privacy on the second side but not on the first side. When the display device 10 displays an image, the first privacy pixel P1 can... The first display screen is able to provide a dedicated display in the direction of the right-viewing area, and the second privacy pixel P2 can provide a dedicated display in the direction of the left-viewing area. Since the first and second sides of the display pixel P3 are not equipped with light-shielding strips 410, that is, the display pixel P3 is not designed for privacy, the display pixel P3 can provide a third display screen in the direction of the left-viewing area and the direction of the right-viewing area for shared display. Thus, the driver's dedicated screen, the passenger's dedicated screen and the shared screen can be displayed simultaneously on the vehicle display device 10, thereby realizing the display needs of multiple content under multiple viewing angles in the privacy mode of the display device 10.

[0038] In this embodiment, reference Figure 5 , Figure 6From a viewing angle along the thickness direction H of the display device 10, one of the light-shielding strips 410 located on the first side of the first privacy pixel P1 does not overlap with the pixel opening 510 of the first privacy pixel P1, and another light-shielding strip 410 located on the second side of the first privacy pixel P1 does not overlap with the pixel opening 510 of the first privacy pixel P1. Similarly, one of the light-shielding strips 410 located on the first side of the second privacy pixel P2 does not overlap with the pixel opening 510 of the second privacy pixel P2, and another light-shielding strip 410 located on the second side of the second privacy pixel P2 does not overlap with the pixel opening 510 of the second privacy pixel P2.

[0039] It is understood that in this embodiment, since the light-shielding strip 410 located on the first side of the first privacy pixel P1 does not overlap with the pixel opening 510 of the first privacy pixel P1, and the other light-shielding strip 410 located on the second side of the first privacy pixel P1 does not overlap with the pixel opening 510 of the first privacy pixel P1, and the light-shielding strip 410 located on the first side of the second privacy pixel P2 does not overlap with the pixel opening 510 of the second privacy pixel P2, and the other light-shielding strip 410 located on the second side of the second privacy pixel P2 does not overlap with the pixel opening 510 of the second privacy pixel P2, that is, the light-shielding strips 410 on both sides of the first privacy pixel P1 and the light-shielding strips 410 on both sides of the second privacy pixel P2 do not block the pixel opening 510, thereby ensuring differentiated privacy while increasing the light emission efficiency of the display device 10. In this embodiment, refer to Figure 3 , Figure 4 From a viewing angle along the thickness direction H of the display device 10, a portion of the light-shielding strip 410 located on the first side of the first privacy pixel P1 overlaps with a portion of the pixel opening 510 of the first privacy pixel P1, and the light-shielding strip 410 located on the second side of the first privacy pixel P1 does not overlap with the pixel opening 510 of the first privacy pixel P1. The light-shielding strip 410 located on the first side of the second privacy pixel P2 does not overlap with the pixel opening 510 of the second privacy pixel P2, and a portion of the light-shielding strip 410 located on the second side of the second privacy pixel P2 overlaps with a portion of the pixel opening 510 of the second privacy pixel P2.

[0040] It is understandable that, since a portion of the light-shielding strip 410 located on the first side of the first privacy pixel P1 overlaps with a portion of the pixel opening 510 of the first privacy pixel P1, and the light-shielding strip 410 located on the second side of the first privacy pixel P1 does not overlap with the pixel opening 510 of the first privacy pixel P1, and the light-shielding strip 410 located on the first side of the second privacy pixel P2 does not overlap with the pixel opening 510 of the second privacy pixel P2, and a portion of the light-shielding strip 410 located on the second side of the second privacy pixel P2 overlaps with a portion of the pixel opening 510 of the second privacy pixel P2, the light-shielding strip 410 located on the first side of the second privacy pixel P2 overlaps with a portion of the pixel opening 510 of the second privacy pixel P1, the light-shielding strip 410 located on the second side of the second privacy pixel P2 overlaps with a portion of the pixel opening 510 of the first privacy pixel P1, the light-shielding strip 410 located on the second side of the second privacy pixel P2 overlaps with a portion of the pixel opening 510 of the first privacy pixel P1, the light-shielding strip 410 located on the first side of the second privacy pixel P2 does not overlap with a portion of the pixel opening 510 of the second privacy pixel P2, the light-shielding strip 410 located on the second side of the second privacy pixel P2 overlaps with a portion of the pixel opening 510 of the first privacy pixel P1 ... first side of the second privacy pixel P2 overlaps with a portion of the pixel opening 510 of the first privacy pixel P1, the light-shielding strip 410 located on the A portion of the pixel opening 510 of the second privacy pixel P2 overlaps with the first side of the first privacy pixel P1, that is, a portion of the pixel opening 510 located on the first side of the first privacy pixel P1 is blocked by the light-blocking strip 410, and a portion of the pixel opening 510 located on the second side of the second privacy pixel P2 is blocked by the light-blocking strip 410. This can improve the light-blocking effect of the light-blocking strip 410 on the first side of the first privacy pixel P1 and the light-blocking effect of the light-blocking strip 410 on the second side of the second privacy pixel P2, thereby improving the privacy effect of the first display screen displayed in the right viewing direction and the privacy effect of the second display screen displayed in the left viewing direction.

The distance b between the edge of the light-shielding strip 410 located on the second side of the first privacy pixel P1 and the edge of the pixel opening 510 of the first privacy pixel P1 is 3um, 3.1um, 3.2um, 3.3um, 3.4um, 3.5um, 3.6um, 3.7um, 3.8um, 3.9um, 4.0um, 4um, 4.1um, 4.2um, 4.3um, 4.4um, 4.5um, 4.6um, 4.7um, 4.8um, 4.9um, or 5um, and the distance b between them is 3um, 3.0um, 4um, 4.1um, 4.2um, 4.3um, 4.4um, 4.5um, 4.6um, 4.7um, 4.8um, 4.9um, or 5um. The distance c between the edge of the light-shielding strip 410 on the first side of the second privacy pixel P2 and the edge of the pixel opening 510 of the second privacy pixel P2 is 3um, 3.1um, 3.2um, 3.3um, 3.4um, 3.5um, 3.6um, 3.7um, 3.8um, 3.9um, 4.0um, 4um, 4.1um, 4.2um, 4.3um, 4.4um, 4.5um, 4.6um, 4.7um, 4.8um, 4.9um, or 5.0um. The distance c between the edge of the light-shielding strip 410 on the second side of the second privacy pixel P2 and the edge of the pixel opening 510 of the second privacy pixel P2 is 3um, 3.1um, 3.2um, 3.3um, 3.4um, 3.5um, 3.6um, 3.7um, 3.8um, 3.9um, 4.0um, 4um, 4.1um, 4.2um, 4.3um, 4.4um, 4.5um, 4.6um, 4.7um, 4.8um, 4.9um, or 5.0um.

[0042] In this embodiment, since the light-shielding strip 410 located on the first side of the first privacy pixel P1 and the edge of the pixel opening 510 of the first privacy pixel P1 are positioned at a viewing angle along the thickness direction H of the display device 10, the distance a between the edge of the light-shielding strip 410 located on the first side of the first privacy pixel P1 and the edge of the pixel opening 510 of the first privacy pixel P1 is not greater than 5 μm, the distance b between the edge of the light-shielding strip 410 located on the second side of the first privacy pixel P1 and the edge of the pixel opening 510 of the first privacy pixel P1 is not less than 3 μm, and the distance c between the edge of the light-shielding strip 410 located on the first side of the second privacy pixel P2 and the edge of the pixel opening 510 of the second privacy pixel P2 is not less than 3 μm. The distance d between the edge of the light-shielding strip 410 on the second side of pixel P2 and the edge of the pixel opening 510 of the second privacy pixel P2 is no greater than 5um. On the one hand, this can improve the light-blocking effect of the light-shielding strip 410 on the first side of the first privacy pixel P1 and the light-blocking effect of the light-shielding strip 410 on the second side of the second privacy pixel P2. On the other hand, it can reduce the large area of ​​the light-shielding strip 410 blocking the pixel opening 510 of the first privacy pixel P1 and the pixel opening 510 of the second privacy pixel P2. Thus, while ensuring the light emission efficiency of the display device 10, it enhances the privacy effect of the first display screen displayed in the right viewing direction and the privacy effect of the second display screen displayed in the left viewing direction.

[0043] In this embodiment, reference Figure 3 , Figure 4 The first light-shielding layer 300 includes a first opening 310 and a second opening 320. In the direction from the substrate 100 to the pixel layer 200, the first opening 310 is disposed above the first privacy pixel P1, and the second opening 320 is disposed above the second privacy pixel P2. In a viewing angle along the thickness direction H of the display device 10, a portion of a light-shielding strip 410 located on the first side of the first privacy pixel P1 overlaps with a portion of the first opening 310, and another light-shielding strip 410 located on the second side of the first privacy pixel P1 does not overlap with the first opening 310; a portion of a light-shielding strip 410 located on the first side of the second privacy pixel P2 does not overlap with the second opening 320, and a portion of another light-shielding strip 410 located on the second side of the second privacy pixel P2 overlaps with a portion of the second opening 320.

[0044] It is understood that in this embodiment, since a portion of the light-shielding strip 410 located on the first side of the first privacy pixel P1 overlaps with a portion of the first opening 310, and another light-shielding strip 410 located on the second side of the first privacy pixel P1 does not overlap with the first opening 310; and a portion of the light-shielding strip 410 located on the first side of the second privacy pixel P2 does not overlap with the second opening 320, and a portion of the other light-shielding strip 410 located on the second side of the second privacy pixel P2 overlaps with a portion of the second opening 320, the light-shielding strips 410 are used to differentiate the light-shielding effect on the first and second sides of the first opening 310, and to differentiate the light-shielding effect on the first and second sides of the second opening 320. The light effects are designed differently, and the light-blocking effects of the first opening 310 and the second opening 320 are designed differently in opposite directions. That is, the first opening 310 is designed to prevent privacy in the direction of the first side, but not in the direction of the second side. Similarly, the second opening 320 is designed to prevent privacy in the direction of the first side, but not in the direction of the second side. When the display device 10 displays a screen, the first privacy pixel P1 can provide a dedicated first display screen facing the right viewing area, and the second privacy pixel P2 can provide a dedicated second display screen facing the left viewing area. Thus, the dedicated screens for the driver and passenger can be displayed simultaneously on the vehicle display device 10.

[0045] In this embodiment, reference Figure 3 , Figure 4 From a viewing angle along the thickness direction H of the display device 10, the edge of the first opening 310 on the first side of the first privacy pixel P1 is located inside the pixel opening 510 of the first privacy pixel P1, and the edge of the first opening 310 on the second side of the first privacy pixel P1 is located outside the pixel opening 510 of the first privacy pixel P1; the edge of the second opening 320 on the first side of the second privacy pixel P2 is located outside the pixel opening 510 of the first privacy pixel P1, and the edge of the second opening 320 on the second side of the second privacy pixel P2 is located inside the pixel opening 510 of the first privacy pixel P1.

[0046] In this embodiment, reference Figure 7 The first light-shielding layer 300 further includes a third opening 330, which is located above the display pixel P3 in the direction from the substrate 100 to the pixel layer 200.

[0047] In this embodiment, from a viewing angle along the thickness direction H of the display device 10, the opening area of ​​the third opening 330 is larger than the opening area of ​​the first opening 310, and the opening area of ​​the third opening 330 is larger than the opening area of ​​the second opening 320. It should be noted that in the above embodiment, the first privacy pixel P1 is used to provide a first display image only to the right viewing area, the second privacy pixel P2 is used to provide a second display image only to the left viewing area, and the display pixel P3 provides a third display image to both the left and right viewing areas. That is, privacy protection is implemented for the first privacy pixel P1 and the second privacy pixel P2, while the display pixel P3 is not designed for privacy protection. Therefore, the third opening 330 has a larger opening area compared to the first opening 310 and the second opening 320.

[0048] In this embodiment, reference Figure 3 , Figure 4 The display device 10 further includes a first pixel definition layer 500 and a second pixel definition layer 600. The second pixel definition layer 600 includes a plurality of second pixel definition portions 610, which are spaced apart in a first direction L of the display device 10. Specifically, from a viewing angle along the thickness direction H of the display device 10, a portion of a light-shielding strip located on a first side of the first privacy pixel protrudes from a second pixel definition portion near an edge of the first privacy pixel; an edge of another light-shielding strip located on a second side of the first privacy pixel is recessed within the orthographic projection of another second pixel definition portion; an edge of another light-shielding strip located on a first side of the second privacy pixel is recessed within the orthographic projection of a second pixel definition portion; and a portion of another light-shielding strip located on a second side of the second privacy pixel protrudes from another second pixel definition portion near an edge of the second privacy pixel.

[0049] It is understood that in this embodiment, since a portion of the light-shielding strip located on the first side of the first privacy pixel protrudes from a second pixel definition portion near an edge of the first privacy pixel, and an edge of the other light-shielding strip located on the second side of the first privacy pixel is recessed within the orthographic projection of another second pixel definition portion, and an edge of the light-shielding strip located on the first side of the second privacy pixel is recessed within the orthographic projection of a second pixel definition portion, and a portion of the other light-shielding strip located on the second side of the second privacy pixel protrudes from another second pixel definition portion near an edge of the second privacy pixel, the light-shielding strips 410 corresponding to the first and second sides of the second pixel definition portions 610 of the first privacy pixel P1 are designed differently, and the light-shielding strips 410 corresponding to the first and second sides of the second privacy pixel P2 are designed differently, the light-shielding effects of the first privacy pixel P1 and the second privacy pixel P2 are different. The design directions are opposite. That is, the first privacy pixel P1 is designed for privacy on the first side, but not on the second side. Similarly, the second privacy pixel P2 is designed for privacy on the second side, but not on the first side. When the display device 10 displays a screen, the first privacy pixel P1 can provide a dedicated first display screen facing the right viewing area, and the second privacy pixel P2 can provide a dedicated second display screen facing the left viewing area. Since the first and second sides of the display pixel P3 do not have light-shielding strips 410, i.e., the display pixel P3 is not designed for privacy, the display pixel P3 can provide a third display screen facing the left and right viewing areas for shared display. Thus, the driver's dedicated screen, the passenger's dedicated screen, and the shared screen can be displayed simultaneously on the vehicle display device 10, thereby meeting the multi-content display needs under the privacy mode of the display device 10.

[0050] In this embodiment, the first pixel definition layer 500 includes a plurality of pixel openings 510.

[0051] It is understood that in this embodiment, the pixel opening 510 of the first privacy pixel P1, the pixel opening 510 of the second privacy pixel P2, and the pixel opening 510 of the display pixel P3 are all pixel openings 510 formed on the first pixel definition layer 500.

[0052] In this embodiment, reference Figure 3 , Figure 4 The display device 10 further includes an encapsulation layer 700, which comprises a first pixel definition layer 500, a second pixel definition layer 600, and a pixel layer 200.

[0053] In this embodiment, reference Figure 3 , Figure 4 The display device 10 further includes a first organic layer 800, which is disposed on a surface of the encapsulation layer 700 away from the substrate 100, wherein the first light-shielding layer 300 is disposed on a surface of the first organic layer 800 away from the substrate 100.

[0054] In this embodiment, the display device 10 further includes a second organic layer 900, which is disposed between the first light-shielding layer 300 and the second light-shielding layer 400.

[0055] Understandably, in Figure 3 , Figure 4 In the schematic diagram, only one organic layer is shown between the first light-shielding layer 300 and the second light-shielding layer 400. In reality, the second organic layer 900 between the first light-shielding layer 300 and the second light-shielding layer 400 can be two, three or more layers.

[0056] In this embodiment, reference Figure 1 , Figure 2 The display device 10 includes a plurality of pixel repeating units PX, each pixel repeating unit PX including a first pixel group PXa, a second pixel group PXb, and a third pixel group PXc. The first pixel group PXa, the second pixel group PXb, and the third pixel group PXc are spaced apart in a second direction M of the display device 10. The first pixel group PXa includes a plurality of first privacy pixels P1 spaced apart in a first direction L. The second pixel group PXb includes a plurality of second privacy pixels P2 spaced apart in the first direction L. The third pixel group PXc includes a plurality of display pixels P3 spaced apart in the first direction L. The first direction L and the second direction M intersect.

[0057] It is understood that in this embodiment, the display device 10 includes multiple pixel repeating units PX, each PX including a first pixel group PXa, a second pixel group PXb, and a third pixel group PXc. The first pixel group PXa, the second pixel group PXb, and the third pixel group PXc are spaced apart in the second direction M of the display device 10. The first pixel group PXa includes multiple first privacy pixels P1 spaced apart in the first direction L, the second pixel group PXb includes multiple second privacy pixels P2 spaced apart in the first direction L, and the third pixel group PXc includes multiple display pixels P3 spaced apart in the first direction L. The first direction L and the second direction M intersect, such that the multiple first pixel groups PXa provide a first display screen, the multiple second pixel groups PXb provide a second display screen, and the multiple pixel groups provide a third display screen. That is, the three different pixel groups can provide different display screens, which is beneficial for realizing the display needs of multiple contents under multiple viewing angles in the privacy mode of the display device 10.

[0058] In this embodiment, reference Figure 1 , Figure 2 The plurality of first privacy pixels P1 in the first pixel group PXa are staggered with the plurality of second privacy pixels P2 in the adjacent second pixel group PXb.

[0059] It is understood that in this embodiment, since the plurality of first privacy pixels P1 in the first pixel group PXa are staggered with the plurality of second privacy pixels P2 in the adjacent second pixel group PXb, the technical solution of this application does not need to change the position of the light-shielding strip 410 when designing the pixel arrangement. It only needs to offset the relative positions of the first privacy pixels P1 and the second privacy pixels P2 when manufacturing the first privacy pixels P1 and the second privacy pixels P2, so that a part of the first privacy pixels P1 and a part of the second privacy pixels P2 are staggered. This can achieve different distances from the first side and the second side of the first privacy pixels P1 to the light-shielding strip 410, and different distances from the second privacy pixels P2 to the first side and the second side, so as to achieve a differentiated design of the privacy protection effect of the first privacy pixels P1 and the second privacy pixels P2. It does not require a complex design of the structure of the second light-shielding layer 400, which helps to reduce the manufacturing difficulty of the display device 10.

[0060] In this embodiment, reference Figure 1 , Figure 2The pixel repeating unit PX includes a plurality of fourth pixel groups PXd, which are spaced apart in the first direction L of the display device 10. The fourth pixel group PXd includes a first privacy pixel P1, a second privacy pixel P2 and a display pixel P3, which are spaced apart in the second direction M of the display device 10.

[0061] In this embodiment, reference Figure 1 , Figure 2 In the first privacy pixel P1 and the second privacy pixel P2 that are arranged adjacently in the fourth pixel group PXd, a portion of the first privacy pixel P1 extends beyond the edge of the first side of the second privacy pixel P2, a portion of the second privacy pixel P2 extends beyond the edge of the second side of the first privacy pixel P1, and the width of the portion of the first privacy pixel P1 that extends beyond the edge of the first side of the second privacy pixel P2 is equal to the width of the portion of the second privacy pixel P2 that extends beyond the edge of the second side of the first privacy pixel P1.

[0063] It is understood that, in this embodiment, since the privacy display mode is set, image data is input to at least one of the first privacy pixel, the second privacy pixel, and the display pixel, so that at least one of the first privacy pixel P1, the second privacy pixel P2, and the display pixel P3 provides a display screen to at least one of the left viewing area direction and the right viewing area direction. This enables the display of at least one of the shared display screen, the driver's exclusive screen, and the passenger's exclusive screen, thereby fulfilling the display requirements under different viewing angles in the privacy mode of the display device 10.

[0064] In this embodiment, the display driving method includes the following steps: In the privacy display mode, image data is input to at least one of the first privacy pixel P1 and the second privacy pixel P2, so that at least one of the first privacy pixel P1 and the second privacy pixel P2 provides a display screen to at least one of the left viewing area direction and the right viewing area direction, and another image data is input to the display pixel P3, so that the display pixel P3 provides another display screen to the left viewing area direction and the right viewing area direction.

Another image data is input to the display pixel P3, so that the display pixel P3 provides another display screen to the left viewing area and the right viewing area. This enables the simultaneous display of a shared display screen and at least one privacy display screen among the driver's exclusive screen and the passenger's exclusive screen, thereby fulfilling the need for multi-content display under multiple viewing angles in the privacy mode of the display device 10.

[0066] In this embodiment, the display driving method includes the following steps: In the privacy display mode, first image data is input to one of the first privacy pixel P1 and the second privacy pixel P2, so that one of the first privacy pixel P1 and the second privacy pixel P2 provides a first display screen to one of the left viewing area direction and the right viewing area direction; second image data is input to the display pixel P3, so that the display pixel P3 provides a second display screen to the left viewing area direction and the right viewing area direction.

This enables the simultaneous display of a shared display screen and one of the privacy display screens for the driver's exclusive screen and the passenger's exclusive screen, thereby fulfilling the need for multi-content display under multiple viewing angles in the privacy mode of the display device 10.

[0068] In this embodiment, the display driving method includes the following steps: In the privacy display mode, first image data is input to one of the first privacy pixel P1 and the second privacy pixel P2, and second image data is input to the other of the first privacy pixel P1 and the second privacy pixel P2, so that one of the first privacy pixel P1 and the second privacy pixel P2 provides a first display screen to one of the left viewing area direction and the right viewing area direction, and the other of the first privacy pixel P1 and the second privacy pixel P2 provides a second display screen to the other of the left viewing area direction and the right viewing area direction. Third image data is input to the display pixel P3, so that the display pixel P3 provides a third display screen to the left viewing area direction and the right viewing area direction.
