Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically, to a display panel, a display module, and a display device. Background Technology

[0002] To enhance vehicle comfort and safety, an increasing number of vehicles are equipped with head-up displays (HUDs). In this technology, the HUD's display area floats above the hood. Because the driver doesn't need to look down or refocus their eyes to observe important driving information, their gaze can remain on the road, improving driving safety. Therefore, HUDs are being widely used in vehicles, providing a better visual experience for drivers and passengers.

[0003] With the development of display technology, head-up displays (HUDs) that achieve dual-display have gradually emerged. These dual displays refer to the virtual image above the hood that includes both a status projection displaying driving information and an augmented reality projection displaying driver assistance information. Augmented Reality HUDs (AR-HUDs) use a specially designed internal optical system to precisely integrate image information with actual traffic conditions, thereby enhancing the driver's perception of the real driving environment.

[0004] In related technologies, AR-HUD achieves augmented reality display and status display separately on two different display panels, and cannot achieve augmented reality display and status display simultaneously on the same display panel. Summary of the Invention

[0005] In view of this, the present invention provides a display panel, a display module, and a display device to improve the presentation of two different display effects, augmented reality display and basic state display, on the same display panel.

[0006] In a first aspect, this application provides a display panel, including a first display area and a second display area;

[0007] The first display area includes a plurality of first sub-pixels, and the first sub-pixels include at least a first color sub-pixel and a second color sub-pixel;

[0008] The second display area includes a plurality of second sub-pixels, and the second sub-pixels include at least a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel; wherein, the transmittance of the first color sub-pixel is greater than the transmittance of the second color sub-pixel, and the transmittance of the second color sub-pixel is greater than the transmittance of the third color sub-pixel;

[0009] The first display area includes a first pixel row and a second pixel row. The first pixel row is located between the second pixel row and the second display area. The total area of ​​the pixel openings of the first color sub-pixels in the first pixel row is smaller than the total area of ​​the pixel openings of the first color sub-pixels in the second pixel row. The total area of ​​the pixel openings of the second color sub-pixels in the first pixel row is larger than the total area of ​​the pixel openings of the second color sub-pixels in the second pixel row.

[0010] Within the second display area, the opening areas corresponding to the second sub-pixels of the same color are the same.

[0011] Secondly, based on the same inventive concept, this application provides a display module, including a polarizer and a display panel;

[0012] The polarizer is located on the light-emitting side of the display panel along the thickness direction of the display module.

[0013] Thirdly, based on the same inventive concept, this application provides a display device, including a display panel.

[0014] Compared with the prior art, the display panel, display module, and display device provided by the present invention achieve at least the following beneficial effects:

[0015] This application provides a display panel, a display module, and a display device. The display panel includes a first display area and a second display area. The first display area includes a plurality of first sub-pixels, and the second display area includes a plurality of second sub-pixels. Each first sub-pixel includes at least a first color sub-pixel and a second color sub-pixel, and each second sub-pixel includes at least a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The first display area includes a first pixel row and a second pixel row. The first pixel row is located between the second pixel row and the second display area. The total area of ​​the pixel openings of the first color sub-pixels in the first pixel row is smaller than the total area of ​​the pixel openings of the first color sub-pixels in the second pixel row, and the total area of ​​the pixel openings of the second color sub-pixels in the first pixel row is larger than the total area of ​​the pixel openings of the second color sub-pixels in the second pixel row. The transmittance of the first color subpixel is greater than that of the second color subpixel. When information is displayed in the first display area, the image transitions from the first color to the second color as the image moves from far to near along the direction from the second pixel row to the first pixel row. This helps to create a sense of integration between the displayed image and the real scene, thereby improving the display effect of augmented reality. In the second display area, the opening areas corresponding to the second subpixels of the same color are the same, and they are used for basic status display. With this setting, by differentiating the first and second subpixels in the same display panel, the first display area is used to achieve the display effect of augmented reality, and the second display area is used to achieve status display. This helps to improve the presentation of two different display effects of augmented reality and status display in the same display panel, thereby helping to reduce production costs.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the technical effects described above at the same time.

[0031] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0033] In related technologies, augmented reality head-up displays (AR-HUD, AR: Augmented Reality) achieve augmented reality display and status display separately on two different display panels. It is not possible to achieve augmented reality display and status display simultaneously on the same display panel, which leads to increased production costs.

[0034] In view of this, the present invention provides a display panel, a display module, and a display device to improve the presentation of two different display effects, augmented reality display and basic state display, on the same display panel.

[0035] Figure 1 The diagram shown is a schematic representation of a display panel provided in an embodiment of this application. Please refer to it. Figure 1 This application provides a display panel 100, including a first display area 01 and a second display area 02; the first display area 01 includes a plurality of first sub-pixels 10, and the first sub-pixels 10 include at least a first color sub-pixel 11 and a second color sub-pixel 12;

[0036] The second display area 02 includes a plurality of second sub-pixels 20, and the second sub-pixels 20 include at least a first color sub-pixel 11, a second color sub-pixel 12 and a third color sub-pixel 13; wherein, the transmittance of the first color sub-pixel 11 is greater than the transmittance of the second color sub-pixel 12, and the transmittance of the second color sub-pixel 12 is greater than the transmittance of the third color sub-pixel 13.

[0037] The first display area 01 includes a first pixel row 011 and a second pixel row 012. The first pixel row 011 is located between the second pixel row 012 and the second display area 02. The total area of ​​the pixel openings of the first color sub-pixels 11 in the first pixel row 011 is smaller than the total area of ​​the pixel openings of the first color sub-pixels 11 in the second pixel row 012. The total area of ​​the pixel openings of the second color sub-pixels 12 in the first pixel row 011 is larger than the total area of ​​the pixel openings of the second color sub-pixels 12 in the second pixel row 012.

[0038] Within the second display area 02, the opening areas corresponding to the second sub-pixels 20 of the same color are the same.

[0039] Specifically, this application provides a display panel 100, which includes a first display area 01 and a second display area 02. The first display area 01 is used to present an augmented reality display effect, and the second display area 02 is used to present a basic state display effect. The first display area 01 includes a plurality of first sub-pixels 10, each first sub-pixel 10 including at least a first color sub-pixel 11 and a second color sub-pixel 12. The transmittance of the first color sub-pixel 11 is greater than the transmittance of the second color sub-pixel 12. The first display area 01 includes a first pixel row 011 and a second pixel row 012. The first pixel row 011 is located between the second pixel row 012 and the second display area 02. The total pixel opening area of ​​the first color sub-pixels 11 in the first pixel row 011 is smaller than the total pixel opening area of ​​the first color sub-pixels 11 in the second pixel row 012. Conversely, the total pixel opening area of ​​the second color sub-pixels 12 in the first pixel row 011 is larger than the total pixel opening area of ​​the second color sub-pixels 12 in the second pixel row 012.

[0040] It is understandable that augmented reality refers to the fusion of virtual information and the real world. The first display area 01 is used to present the display effect of augmented reality, that is, along the direction from the second pixel row 012 to the first pixel row 011, the displayed image is from far to near. This application sets the total area of ​​the pixel opening of the first color sub-pixel 11 in the first pixel row 011 to be smaller than the total area of ​​the pixel opening of the first color sub-pixel 11 in the second pixel row 012, and the total area of ​​the pixel opening of the second color sub-pixel 12 in the first pixel row 011 to be larger than the total area of ​​the pixel opening of the second color sub-pixel 12 in the second pixel row 012, through the difference of different color sub-pixels. The design incorporates color transitions as the image moves from far to near, providing a visual transition effect for the observer and enhancing the augmented reality display. Furthermore, since the content displayed in the second pixel row 012 is actually farther from the observer than that in the first pixel row 011, to improve the display effect of the second pixel row 012, the total area of ​​the pixel openings of the first color sub-pixels 11 with higher transmittance in the second pixel row 012 is set to be greater than the total area of ​​the pixel openings of the second color sub-pixels 12 with lower transmittance in the first pixel row 011. This improves the overall display clarity of the display panel 100 under sunlight.

[0041] It should be noted that the accompanying drawings of this application only illustrate that the first pixel row 011 and the second pixel row 012 are not adjacent, but this application is not limited to this. The first pixel row 011 and the second pixel row 012 can be located in the first display area 01, and the first pixel row 011 can be located between the second pixel row 012 and the second display area 02. For example, the first pixel row 011 and the second pixel row 012 can also be two adjacent pixel rows.

[0042] Please continue to refer to this. Figure 1 The second display area 02 includes a plurality of second sub-pixels 20. Each second sub-pixel 20 includes at least a first color sub-pixel 11, a second color sub-pixel 12, and a third color sub-pixel 13. The transmittance of the first color sub-pixel 11 is greater than that of the second color sub-pixel 12, and the transmittance of the second color sub-pixel 12 is greater than that of the third color sub-pixel 13. Within the second display area 02, the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 are evenly arranged, which is beneficial for achieving multiple color displays within the second display area 02 and for improving the display uniformity within the second display area.

[0043] It should be noted that the second display area 02 is used to present the basic status display effect, that is, to display various basic information. Multiple colors are used to clearly display the basic information, which is conducive to improving the user's experience and comfort. Therefore, the second display area 02 is set to include at least a first color sub-pixel 11, a second color sub-pixel 12, and a third color sub-pixel 13. The first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 are evenly arranged, which is conducive to realizing the display of multiple colors in the second display area 02 and improving the display uniformity in the second display area.

[0044] It is understood that the display panel 100 provided in this application, with its differentiated distribution of the first sub-pixels 10 in the first display area 01, is beneficial to improving the display effect of augmented reality; and with its uniformly distributed second sub-pixels 20 in the second display area 02, displaying multiple colors, it is beneficial to improve the basic display effect of the second display area 02 and enhance the display uniformity of the second display area 02. This application, through the differentiated design of the sub-pixel distribution in the first display area 01 and the second display area 02, achieves two different display effects within the same display panel 100. Compared to presenting two different display effects in two separate display panels, this also helps to save production costs. It should be noted that the first display area 01 includes a first pixel unit 010, and one first pixel unit 010 includes two first sub-pixels 10; the second display area 02 includes a second pixel unit 020, and one second pixel unit 020 includes one first color sub-pixel 11, one second color sub-pixel 12, and one third color sub-pixel 13, that is, one pixel unit includes three second sub-pixels 20; therefore, when the pixel opening area of ​​a single first color sub-pixel 11 in the first display area 01 is less than 1.5 times the pixel opening area of ​​a single first color sub-pixel 11 in the second display area 02, the first display area... When the pixel aperture area of ​​a single second color sub-pixel 12 in the first display area 01 is less than 1.5 times the pixel aperture area of ​​a single second color sub-pixel 12 in the second display area 02, the pixel aperture area of ​​the first pixel unit 010 is less than the pixel aperture area of ​​the second pixel unit 020. Therefore, the number of first sub-pixels 10 that can be set in the first display area 01 per inch is greater than the number of second sub-pixels 20 that can be set in the second display area 02. Thus, the pixel density in the first display area 01 is relatively large. This setting is beneficial to improving the clarity of the first display area 01, thereby improving the visual effect of the first display area 01.

[0045] This application provides an optional implementation where, when the display panel 100 is applied to an in-vehicle augmented reality head-up display (VR-HUD), the first display area 01 is used to display road navigation information, and the second display area 02 is used to display instrument status. In the first display area 01, the road navigation information is displayed with an augmented reality effect. To achieve a perspective where the image moves from far to near, the displayed icon moves within the first display area 01 along the direction from the second pixel row 012 to the first pixel row 011, transitioning from a first color to a second color. This facilitates a sense of integration between the navigation information and the real-world scene. Simultaneously, to enhance the warning effect on the driver, the second color sub-pixel 12 can be selected as a color with a warning effect. Optionally, the second color sub-pixel 12 is a red sub-pixel, but this application is not limited to this. In the second display area 02, the vehicle's instrument status information is displayed. This configuration, when the display panel 100 provided in this application is applied to an in-vehicle augmented reality head-up display, helps to achieve different display effects on the same display panel 100.

[0046] It should be noted that this application does not specifically limit the specific colors of the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13. Optionally, the first color sub-pixel 11 is a green sub-pixel, the second color sub-pixel 12 is a red sub-pixel, and the third color sub-pixel 13 is a blue sub-pixel. With this setting, the first display area 01 includes at least green and red sub-pixels. Within the first display area 01, along the direction from the second pixel row 012 to the first pixel row 011, the displayed content transitions from green to red, creating an effect that is integrated with reality, and red has a stronger warning effect. The second display area 02 includes at least green, red, and blue sub-pixels. Within the second display area 02, it is beneficial to present a display effect of multiple colors, and the display uniformity is relatively high.

[0047] It should also be noted that the accompanying drawings in this application are for illustrative purposes only and do not represent the actual size and structure of the display panel.

[0048] Please continue to refer to this. Figure 1 This application provides an optional implementation in which, within the first display area 01, the opening areas corresponding to the first sub-pixels 10 of the same color are the same; the number of first color sub-pixels 11 in the first pixel row 011 is less than the number of first color sub-pixels 11 in the second pixel row 012; and the number of second color sub-pixels 12 in the first pixel row 011 is greater than the number of second color sub-pixels 12 in the second pixel row 012.

[0049] Specifically, within the first display area 01, the total area of ​​the pixel openings of the first color sub-pixels 11 in the first pixel row 011 is smaller than the total area of ​​the pixel openings of the first color sub-pixels 11 in the second pixel row 012, and the total area of ​​the pixel openings of the second color sub-pixels 12 in the first pixel row 011 is larger than the total area of ​​the pixel openings of the second color sub-pixels 12 in the second pixel row 012. This embodiment achieves this by setting the number of first color sub-pixels 11 in the first pixel row 011 to be less than the number of first color sub-pixels 11 in the second pixel row 012, and the number of second color sub-pixels 12 in the first pixel row 011 to be greater than the total area of ​​the pixel openings of the second color sub-pixels 12 in the second pixel row 012. The number of second-color sub-pixels 12 in the two-pixel row 012 is adjusted to ensure that, within the first display area 01, the total area of ​​the pixel openings of the first-color sub-pixels 11 in the first pixel row 011 is smaller than the total area of ​​the pixel openings of the first-color sub-pixels 11 in the second pixel row 012, and the total area of ​​the pixel openings of the second-color sub-pixels 12 in the first pixel row 011 is larger than the total area of ​​the pixel openings of the second-color sub-pixels 12 in the second pixel row 012. This arrangement, through the differentiated design of different color sub-pixels, helps to provide the observer with a visual transition effect, thereby improving the display effect of augmented reality.

[0050] Figure 2 The diagram shown is a schematic diagram of another display panel provided in an embodiment of this application. Please refer to it. Figure 2 This application provides an optional implementation in which the height of the pixel opening of the first color sub-pixel 11 in the first display area 01 along the first direction is equal to the height of the pixel opening of the first color sub-pixel 11 in the second display area 02 along the first direction; the width of the pixel opening of the first color sub-pixel 11 in the first display area 01 along the second direction is greater than the width of the pixel opening of the first color sub-pixel 11 in the second display area 02 along the second direction; wherein, the first direction and the second direction intersect, and the first direction is the arrangement direction of the first pixel row 011 and the second pixel row 012; the height of the pixel opening of the second color sub-pixel 12 in the first display area 01 along the first direction is equal to the height of the pixel opening of the second color sub-pixel 12 in the second display area 02 along the first direction; the width of the pixel opening of the second color sub-pixel 12 in the first display area 01 along the second direction is greater than the width of the pixel opening of the second color sub-pixel 12 in the second display area 02 along the second direction.

[0051] Specifically, such as Figure 2As shown, the total area of ​​the pixel openings of the first color sub-pixel 11 in the first pixel row 011 is smaller than the total area of ​​the pixel openings of the first color sub-pixel 11 in the second pixel row 012, and the total area of ​​the pixel openings of the second color sub-pixel 12 in the first pixel row 011 is larger than the total area of ​​the pixel openings of the second color sub-pixel 12 in the second pixel row 012. Through the differentiated design of different color sub-pixels, it is beneficial to provide the observer with a visual transition effect, thereby improving the display effect of augmented reality. Meanwhile, in this embodiment, the first sub-pixel 10 in the first display area 01 is enlarged relative to the second sub-pixel 20 in the second display area 02. The first display area 01 includes a first pixel unit 010, and one first pixel unit 010 includes two first sub-pixels 10; the second display area 02 includes a second pixel unit 020, and one second pixel unit 020 includes one first color sub-pixel 11, one second color sub-pixel 12, and one third color sub-pixel 13, that is, one pixel unit includes three second sub-pixels 20; when the pixel aperture area of ​​a single first color sub-pixel 11 in the first display area 01 is less than 1.5 times the pixel aperture area of ​​a single first color sub-pixel 11 in the second display area 02, the pixel aperture area of ​​a single second color sub-pixel 20 in the first display area 01 is enlarged. When the pixel aperture area of ​​the color sub-pixel 12 is less than 1.5 times the pixel aperture area of ​​a single second color sub-pixel 12 in the second display area 02, the pixel aperture area of ​​the first pixel unit 010 is less than the pixel aperture area of ​​the second pixel unit 020. Therefore, the number of first sub-pixels 10 that can be set in the first display area 01 per inch is greater than the number of second sub-pixels 20 that can be set in the second display area 02. As a result, the pixel density in the first display area 01 is larger, which is beneficial to improving the clarity of the first display area 01 and thus improving the visual effect of the first display area 01. At the same time, enlarging the first sub-pixels 10 in the first display area 01 relative to the second sub-pixels 20 in the second display area 02 is also beneficial to reducing the manufacturing difficulty of the first display area 01.

[0052] Figure 3 The diagram shown is a schematic diagram of another display panel provided in an embodiment of this application. Please refer to it. Figure 3 In an optional implementation, the first sub-pixel 10 further includes a third color sub-pixel 13, and the total area of ​​the pixel openings of the third color sub-pixel 13 in a single first pixel row 011 is equal to the total area of ​​the pixel openings of the third color sub-pixel 13 in a single second pixel row 012.

[0053] Specifically, in this embodiment, the first sub-pixel 10 further includes a third color sub-pixel 13. That is, the first display area 01 includes not only the first color sub-pixel 11 and the second color sub-pixel 12, but also the third color sub-pixel 13. The total area of ​​the pixel opening of the third color sub-pixel 13 in a single first pixel row 011 is the same as the total area of ​​the pixel opening of the third color sub-pixel 13 in a single second pixel row 012. With this configuration, the addition of the third color sub-pixel 13 to the first display area 01 not only improves the display effect of augmented reality, but also facilitates the display of multiple colors in the first display area 01, further enhancing the visual effect of the first display area 01.

[0054] It should be noted that the first display area 01 is mainly used to present the display effect of augmented reality, and the requirements for the variety of colors are not high. Under the premise of improving the display effect of augmented reality, when multiple colors are required, a third color sub-pixel 13 can be added. The specific situation can be designed according to actual needs, and this application does not make specific limitations.

[0055] Figure 4 The diagram shown is a schematic diagram of another display panel provided in an embodiment of this application. Please refer to it. Figure 4 This application provides an optional implementation in which the height of the pixel opening of the third color sub-pixel 13 in the first display area 01 along the first direction is equal to the height of the pixel opening of the third color sub-pixel 13 in the second display area 02 along the first direction; the width of the pixel opening of the third color sub-pixel 13 in the first display area 01 along the second direction is greater than the width of the pixel opening of the third color sub-pixel 13 in the second display area 02 along the second direction; the first direction is the arrangement direction of the first pixel row 011 and the second pixel row 012.

[0056] Specifically, please refer to Figure 4The first display area 01 includes a first color sub-pixel 11, a second color sub-pixel 12, and a third color sub-pixel 13. The total area of ​​the pixel openings of the first color sub-pixels 11 in the first pixel row 011 is smaller than the total area of ​​the pixel openings of the first color sub-pixels 11 in the second pixel row 012, and the total area of ​​the pixel openings of the second color sub-pixels 12 in the first pixel row 011 is larger than the total area of ​​the pixel openings of the second color sub-pixels 12 in the second pixel row 012. This differentiated design of the different color sub-pixels helps to provide the observer with a visual transition effect, thereby achieving… This improves the display effect of augmented reality. In this embodiment, a third color sub-pixel 13 is provided in the first display area 01. The height of the pixel opening of the first color sub-pixel 11 in the first display area 01 along the first direction is equal to the height of the pixel opening of the first color sub-pixel 11 in the second display area 02 along the first direction. The width of the pixel opening of the first color sub-pixel 11 in the first display area 01 along the second direction is greater than the width of the pixel opening of the first color sub-pixel 11 in the second display area 02 along the second direction. The second color sub-pixel 12 in the first display area 01... The height of the pixel opening along the first direction is equal to the height of the pixel opening of the second color sub-pixel 12 in the second display area 02 along the first direction, and the width of the pixel opening of the second color sub-pixel 12 in the first display area 01 along the second direction is greater than the width of the pixel opening of the second color sub-pixel 12 in the second display area 02 along the second direction; the height of the pixel opening of the third color sub-pixel 13 in the first display area 01 along the first direction is equal to the height of the pixel opening of the third color sub-pixel 13 in the second display area 02 along the first direction, and the width of the pixel opening of the third color sub-pixel 13 in the first display area 01 along the second direction is greater than the width of the pixel opening of the third color sub-pixel 13 in the second display area 02 along the second direction; that is, the first sub-pixel 10 in the first display area 01 is enlarged relative to the second sub-pixel 20 in the second display area 02. This setting is beneficial for the first display area 01 to achieve multiple color displays, thereby improving the visual effect of the first display area 01 and making it suitable for more application scenarios. At the same time, the larger size of the first sub-pixel 10 in the first display area 01 helps to reduce the manufacturing difficulty of the first display area 01.

[0057] Please refer to Figure 1 This application provides an optional implementation where the pixel aperture area of ​​a single first color sub-pixel 11 in the first display area 01 is equal to the pixel aperture area of ​​a single first color sub-pixel 11 in the second display area 02; and the pixel aperture area of ​​a single second color sub-pixel 12 in the first display area 01 is equal to the pixel aperture area of ​​a single second color sub-pixel 12 in the second display area 02.

[0058] Specifically, please refer to Figure 1In this embodiment, the pixel aperture area of ​​a first color sub-pixel 11 in the first display area 01 is the same as the pixel aperture area of ​​a first color sub-pixel 11 in the second display area 02; the pixel aperture area of ​​a second color sub-pixel 12 in the first display area 01 is the same as the pixel aperture area of ​​a second color sub-pixel 12 in the second display area 02; that is, in the first display area 01 and the second display area 02, the pixel aperture areas corresponding to sub-pixels of the same color are the same. This setting helps to reduce the manufacturing process difficulty of the display panel 100.

[0059] Please refer to Figure 3 This application provides an optional implementation in which the first display area 01 includes a first pixel column 013, and the first sub-pixel 10 further includes a third color sub-pixel 13. All sub-pixels in the first pixel column 013 are third color sub-pixels 13. The third color sub-pixels 13 in the first pixel column 013 are arranged along a first direction, which is the arrangement direction of the first pixel row 011 and the second pixel row 012. The pixel aperture area of ​​the third color sub-pixel 13 in the first display area 01 is equal to the pixel aperture area of ​​the third color sub-pixel 13 in the second display area 02.

[0060] Specifically, please refer to Figure 3 The first display area 01 also includes a first pixel column 013, and the first sub-pixel 10 also includes a third color sub-pixel 13. All sub-pixels in the first pixel column 013 are third color sub-pixels 13. The pixel aperture area of ​​a first color sub-pixel 11 in the first display area 01 is the same as the pixel aperture area of ​​a first color sub-pixel 11 in the second display area 02; the pixel aperture area of ​​a second color sub-pixel 12 in the first display area 01 is the same as the pixel aperture area of ​​a second color sub-pixel 12 in the second display area 02; the pixel aperture area of ​​a third color sub-pixel 13 in the first display area 01 is the same as the pixel aperture area of ​​a third color sub-pixel 13 in the second display area 02. That is, in the first display area 01 and the second display area 02, the pixel aperture areas corresponding to sub-pixels of the same color are the same. This setting helps to reduce the manufacturing process difficulty of the display panel 100. Meanwhile, the first display area 01 also includes a third color sub-pixel 13. While improving the display effect of augmented reality, the first display area 01 is also conducive to displaying multiple colors, which further enhances the visual effect of the first display area 01.

[0061] It should be noted that, please refer to Figures 1 to 4 , Figures 1 to 4The embodiments shown all involve sub-pixels of the same color having the same pixel opening size within the first display area 01. The display effect of augmented reality is improved by differentiating the number of sub-pixels of different colors in each pixel row. However, this application is not limited to this and can also improve the display effect of augmented reality by differentiating the size of the pixel opening of sub-pixels in each column.

[0062] Figure 5 The diagram shown is a schematic diagram of another display panel provided in an embodiment of this application. Please refer to it. Figure 5 This application provides an optional implementation in which the number of first sub-pixels 10 in a row is the same as the number of second sub-pixels 20 in a row; along a first direction, the height of the pixel opening of the first color sub-pixel 11 in the first pixel row 011 is the same as the height of the pixel opening of the first color sub-pixel 11 in the second pixel row 012; the width of the pixel opening of the first color sub-pixel 11 in the first pixel row 011 along a second direction is smaller than the width of the pixel opening of the first color sub-pixel 11 in the second pixel row 012 along a second direction; the first direction is the arrangement direction of the first pixel row 011 and the second pixel row 012, and the second direction intersects with the first direction; along the first direction, the height of the pixel opening of the second color sub-pixel 12 in the first pixel row 011 is the same as the height of the pixel opening of the second color sub-pixel 12 in the second pixel row 012; the width of the pixel opening of the second color sub-pixel 12 in the first pixel row 011 along a second direction is greater than the width of the pixel opening of the second color sub-pixel 12 in the second pixel row 012 along a second direction.

[0063] Specifically, to improve the augmented reality display effect of the first display area 01, this application differentiates the design of the first sub-pixels 10 of the first display area 01. The total area of ​​the pixel openings of the first color sub-pixels 11 in the first pixel row 011 is set to be smaller than the total area of ​​the pixel openings of the first color sub-pixels 11 in the second pixel row 012, and the total area of ​​the pixel openings of the second color sub-pixels 12 in the first pixel row 011 is larger than the total area of ​​the pixel openings of the second color sub-pixels 12 in the second pixel row 012. This facilitates a visual transition effect for the observer. This embodiment achieves the transition effect by keeping the number of first sub-pixels 10 in one row and the number of second sub-pixels 20 in one row the same, while changing the size of the pixel opening areas of the first color sub-pixels 11 and the second color sub-pixels 12 in the first display area 01. Specifically, the height of the pixel opening of the first color sub-pixel 11 in the first pixel row 011 is equal to the height of the pixel opening of the first color sub-pixel 11 in the second pixel row 012, and the height of the pixel opening of the second color sub-pixel 12 in the first pixel row 011 is equal to the height of the pixel opening of the second color sub-pixel 12 in the second pixel row 012; the width of the pixel opening of the first color sub-pixel 11 in the first pixel row 011 along the second direction is less than the width of the pixel opening of the first color sub-pixel 11 in the second pixel row 012 along the second direction, and the width of the pixel opening of the second color sub-pixel 12 in the first pixel row 011 along the second direction is greater than the width of the pixel opening of the second color sub-pixel 12 in the second pixel row 012 along the second direction. That is, the height of the first sub-pixel 10 is set to be the same, and the width of the first sub-pixel 10 is changed, thereby changing the total area of ​​the pixel opening of the first color sub-pixel 11 and the total area of ​​the pixel opening of the second color sub-pixel 12 in each pixel row, thereby achieving a visual transition effect, which is beneficial to improving the display effect of the augmented reality in the first display area 01.

[0064] Figure 6 The diagram shown is a schematic diagram of another display panel provided in an embodiment of this application. Please refer to it. Figure 6 This application provides an optional implementation in which the first display area 01 includes a first pixel column 013, the first sub-pixel 10 further includes a third color sub-pixel 13, all sub-pixels in the first pixel column 013 are third color sub-pixels 13, and the third color sub-pixels 13 in the first pixel column 013 are arranged along a first direction; the pixel aperture area of ​​the third color sub-pixel 13 in the first display area 01 is equal to the pixel aperture area of ​​the third color sub-pixel 13 in the second display area 02.

[0065] Specifically, please refer to Figure 6The first display area 01 also includes a first pixel column 013, and the first sub-pixel 10 also includes a third color sub-pixel 13. All sub-pixels in the first pixel column 013 are third color sub-pixels 13. In the first display area 01, the width of the pixel opening of the first color sub-pixel 11 in the first pixel row 011 along the second direction is smaller than the width of the pixel opening of the first color sub-pixel 11 in the second pixel row 012 along the second direction. The width of the pixel opening of the second color sub-pixel 12 in the first pixel row 011 along the second direction is larger than the width of the pixel opening of the second color sub-pixel 12 in the second pixel row 012 along the second direction. That is, by changing the width of the pixel opening of the first sub-pixel 10, the total area of ​​the pixel opening of the first color sub-pixel 11 and the total area of ​​the pixel opening of the second color sub-pixel 12 in each pixel row are changed, thereby achieving a visual transition effect, which is beneficial to improving the augmented reality display effect of the first display area 01. Meanwhile, this embodiment provides a third color sub-pixel 13 in the first display area 01, which not only improves the augmented reality display effect of the first display area 01, but also helps the first display area 01 to display multiple colors, further enhancing the visual effect of the first display area 01.

[0066] Please continue to refer to this. Figure 6 This application provides an optional implementation in which the sub-pixels in the first sub-pixel 10 and the second sub-pixel 20 in the same column have the same color; and in the first sub-pixel 10 or the second sub-pixel 20 in the same row, the arrangement order of the sub-pixels is the second color sub-pixel 12, the first color sub-pixel 11 and the third color sub-pixel 13.

[0067] Specifically, in the display panel 100, the number of first sub-pixels 10 in a row of the first display area 01 is the same as the number of second sub-pixels 20 in a row of the second display area 02. In the same column of first sub-pixels 10 and second sub-pixels 20, the sub-pixel colors are the same. In the same row of first sub-pixels 10 or second sub-pixels 20, the arrangement order of the sub-pixels is second color sub-pixel 12, first color sub-pixel 11 and third color sub-pixel 13. In the first display area 01, the width of the pixel opening of the first color sub-pixel 11 in the first pixel row 011 along the second direction is smaller than the width of the pixel opening of the first color sub-pixel 11 in the second pixel row 012 along the second direction, and the width of the pixel opening of the second color sub-pixel 12 in the first pixel row 011 along the second direction is larger than the width of the pixel opening of the second color sub-pixel 12 in the second pixel row 012 along the second direction. That is, by changing the width of the pixel opening of the first sub-pixel 10, the total area of ​​the pixel opening of the first color sub-pixel 11 and the total area of ​​the pixel opening of the second color sub-pixel 12 in each pixel row are changed, thereby achieving a visual transition effect and improving the augmented reality display effect of the first display area 01. Simultaneously, this embodiment provides a third color sub-pixel 13 in the first display area 01, which, while improving the augmented reality display effect of the first display area 01, also facilitates the display of multiple colors in the first display area 01, further enhancing the visual effect of the first display area 01.

[0068] Based on the same inventive concept, this application provides a display module. Figure 7 The diagram shown is a schematic diagram of a display module provided in an embodiment of this application. Figure 8 The image shown is of this application. Figure 7 Please refer to the schematic diagram of the cross section along AA'. Figure 7 and Figure 8 The display module 200 includes a polarizer 210 and a display panel 100, which can be any type of display panel 100 provided in this application; the polarizer 210 is located on the light-emitting surface side of the display panel 100 along the thickness direction of the display module 200.

[0069] It should be noted that the embodiments of the display device 300 provided in this application can refer to the embodiments of the display panel 100 described above, and will not be repeated here.

[0070] Please continue to refer to this. Figure 7 and Figure 8 Optionally, the polarizer 210 is used to compensate for the display viewing angle. Within the first display area 01, along the first direction, the compensation angle of the polarizer 210 tends to decrease, and the compensation angle is 20° to 70°.

[0071] Specifically, this application uses a differentiated design for the polarizer 210, which is beneficial for compensating for the display viewing angle. Along the first direction (the direction from the second display area 02 to the first display area 01), the compensation angle of the polarizer 210 gradually decreases, and the compensation angle is 20° to 70°. This application provides one optional implementation where the compensation angle is 20° to 60° along the first direction; another optional implementation where the compensation angle is 30° to 60° along the first direction; and yet another optional implementation where the compensation angle is 30° to 70° along the first direction. When this application is applied to an in-vehicle augmented reality head-up display, the first display area 01 is located on the windshield of the car. Along the first direction, the observer's viewing angle gradually decreases. Therefore, within the first display area 01, along the first direction, the compensation angle of the polarizer 210 decreases. When the observer's gaze falls on the position furthest from the second display area 02 in the first display area 01, the compensation angle is at its minimum of 20°. At this point, when the compensation angle is less than 20°, the contrast of the first display area 01 is low. When the observer's gaze falls on the position closest to the second display area 02 in the first display area 01, the compensation angle is at its maximum of 70°. At this point, when the compensation angle is greater than 70°, the contrast of the first display area 01 is low. A low contrast in the first display area 01 is detrimental to improving the visual effect of the display module 200. Therefore, differentiated settings of the compensation viewing angle of the polarizer 210 are beneficial to improving the display effect of the display module 200. This application only illustrates the application of the display module 200 in an in-vehicle augmented reality head-up display area and is not limited thereto.

[0072] It should be noted that the compensation angle of the polarizer 210 is differentiated mainly by setting the concentration of additives in the polarizer 210 material, but this application is not limited to this. For example, it can also be achieved by differentiating the thickness of the polarizer 210.

[0073] Based on the same inventive concept, this application also provides a display device. Figure 9 The diagram shown is a schematic representation of a display device provided in an embodiment of this application. Please refer to it. Figure 9 The display device 300 includes a display panel 100, which includes any of the display panels 100 provided in this application.

[0074] It should be noted that the embodiments of the display device 300 provided in this application can refer to the embodiments of the display panel 100 described above, and will not be repeated here. The display device 300 provided in this application can be any product and component with display function, such as a mobile phone, tablet computer, television, touch screen, laptop computer, or navigator.

[0075] As can be seen from the above embodiments, the display panel, display module, and display device provided by the present invention achieve at least the following beneficial effects:

[0076] This application provides a display panel, a display module, and a display device. The display panel includes a first display area and a second display area. The first display area includes a plurality of first sub-pixels, and the second display area includes a plurality of second sub-pixels. Each first sub-pixel includes at least a first color sub-pixel and a second color sub-pixel, and each second sub-pixel includes at least a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The first display area includes a first pixel row and a second pixel row. The first pixel row is located between the second pixel row and the second display area. The total area of ​​the pixel openings of the first color sub-pixels in the first pixel row is smaller than the total area of ​​the pixel openings of the first color sub-pixels in the second pixel row, and the total area of ​​the pixel openings of the second color sub-pixels in the first pixel row is larger than the total area of ​​the pixel openings of the second color sub-pixels in the second pixel row. The transmittance of the first color subpixel is greater than that of the second color subpixel. When information is displayed in the first display area, the image transitions from the first color to the second color as the image moves from far to near along the direction from the second pixel row to the first pixel row. This helps to create a sense of integration between the displayed image and the real scene, thereby improving the display effect of augmented reality. In the second display area, the opening areas corresponding to the second subpixels of the same color are the same, and they are used for basic status display. With this setting, by differentiating the first and second subpixels in the same display panel, the first display area is used to achieve the display effect of augmented reality, and the second display area is used to achieve status display. This helps to improve the presentation of two different display effects of augmented reality and status display in the same display panel, thereby helping to reduce production costs.

[0077] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
