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

[0002] The key to head-up display (HUD) technology is generating clear images that do not distract the driver. Image quality is related to the chief ray angle (CRA) of the optical engine and the light pattern of the display screen.

[0003] In conventional optomechanical systems, the center of the opening area on the array substrate side of the display screen and the center of the opening of the black matrix on the color filter substrate of the display screen are overlapped in the thickness direction. The display screen with this architecture has the highest light output brightness at a normal viewing angle and lower light output brightness at a wide viewing angle. Therefore, in order to adjust the molding quality, it is necessary to tilt the display screen to match the main ray angle of the optomechanical system. Invention Overview

[0039] Optionally, in some embodiments of this application, the reflecting surfaces of the first and second reflectors are both curved surfaces, and the reflective component includes the windshield component of an automobile.

[0040] On the other hand, embodiments of this application also provide a display device, which includes the display system as described in any of the above embodiments.

[0041] The display system and display device of this application improve the light emission pattern of the display panel and increase the light emission brightness at large viewing angles by offsetting the array substrate and the opposing substrate of the display panel, such that the center of the opening area of ​​each light emission channel of the display panel is offset relative to the center of the sub-pixel opening in the top view.

[0042] This application provides a display system and display device, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0043] Referring to Figure 1, this application embodiment provides a display system 100, which includes a display panel 10 and a reflective component 20.

[0044] The display panel 10 is configured to output an image source. The reflective component 20 is configured to receive the image source and project it onto the human eye to form a virtual image xx.

[0045] The display system 100 also includes a backlight module 30 that provides a surface light source for the display panel 10. The display panel 10 is located on the light-emitting side of the backlight module 30. The plane containing the backlight module 30 is parallel to the plane containing the display panel 10.

[0046] It is understood that the plane on which the display panel 10 is located is the plane on which the base of the display panel 10 is located, and the plane on which the backlight module 30 is located is the plane on which the backplate of the backlight module 30 is located. The plane on which the backlight module 30 is located is parallel to the plane on which the display panel 10 is located, so that the backlight module 30 and the display panel 10 are equidistantly positioned, saving assembly space.

[0047] Optionally, in some embodiments of the display system 100 of this application, referring to Figures 2 and 3, the display panel 10 includes an array substrate 11 and a counter substrate 12 disposed opposite to each other. The array substrate 11 includes data lines 101 and scan lines 102, which are intersected to form a plurality of opening regions 103. The counter substrate 12 includes a black matrix layer 201, on which a plurality of sub-pixel openings 12a are formed. In the thickness direction F3 of the display panel 10, a sub-pixel opening 12a and an opening region 103 are correspondingly disposed and form a light emission channel 301.

[0048] In the top view of each light-emitting channel 301 of the display panel 10, the center of the opening area 103 is offset relative to the center of the sub-pixel opening 12a.

[0049] It should be noted that the offset between the array substrate 11 and the opposing substrate 12 can be based on the array substrate 11, with the opposing substrate 12 offset left and right along a direction parallel to the scan line 102, as shown in Figure 2; or it can be based on the array substrate 11, with the opposing substrate 12 offset up and down along a direction parallel to the data line 101, as shown in Figure 3; or it can be based on the array substrate 11, with the opposing substrate 12 first offset left and right, then offset up and down, and so on. In some embodiments, the array substrate 11 can also be moved based on the opposing substrate 12.

[0050] It needs to be explained that in existing display panels, the array substrate and the color filter substrate are positioned directly opposite each other. That is, in the thickness direction of the display panel, the center of the opening area of ​​the array substrate is directly opposite the center of the sub-pixel opening on the black matrix of the color filter substrate, maximizing the luminous brightness at a positive viewing angle. However, when existing display panels are applied to optomechanical display systems, since the imaging quality is related to the chief ray angle (CRA) of the optomechanical system and the light pattern of the display panel, in order to maximize the light output effect, with the chief ray angle of the optomechanical system fixed, it can be seen from the light output pattern of existing display panels (as shown in Figure 4a) and the brightness attenuation curve (as shown in Figure 4b) that the light output brightness at a wide viewing angle is relatively small, which can easily cause color shift in the display.

[0051] The display system 100 of this application offsets the array substrate 11 and the opposing substrate 12 of the display panel 10, so that in the top view of each light emission channel 301 of the display panel 10, the center of the opening area 103 is offset relative to the center of the sub-pixel opening 12a, thereby improving the light emission pattern of the display panel 10, widening the brightness attenuation curve, and improving the light emission brightness at a large angle view, so as to improve color shift.

[0052] Optionally, in some embodiments of this application, in the top view of each light-emitting channel 301 of the display panel 10, in the first direction F1, the distance L1 between the center z1 of the opening area 103 and the center z2 of the sub-pixel opening 12a is between 1.4% and 5.6% of the width of the sub-pixel opening 12a.

[0053] It is understandable that the distance L1 between the center z1 of the opening area 103 and the center z2 of the sub-pixel opening 12a is the relative offset between the opening area 103 and the sub-pixel opening 12a. This distance L1 is related to the size of the sub-pixel opening 12a. The larger the distance L1 is relative to the width of the sub-pixel opening 12a, the larger the relative offset between the opening area 103 and the sub-pixel opening 12a, and vice versa. When the distance L1 is too large, the light pattern emitted by the display panel will be cut off; when the distance L1 is too small, the effect on improving the brightness of the emitted light at a wide viewing angle is limited. Therefore, in order to ensure improved brightness of the emitted light at a wide viewing angle and better improve color shift, the percentage of the distance L1 between the center z1 of the opening area 103 and the center z2 of the sub-pixel opening 12a to the width of the sub-pixel opening 12a is selected to be between 1.4% and 5.6%.

[0054] The percentage of the distance L1 between the center z1 of the opening region 103 and the center z2 of the sub-pixel opening 12a to the width of the sub-pixel opening 12a can be 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2.0%, 2.1%, 2.2%, 2.3%, 2.4%, 2.5%, 2.6%, 2.7%, 2.8%, 2.9%, 3.0%, 3.1%, 3.2%, 3.3%, 3.4%, 3.5%, 3.6%, 3.7%, 3.8%, 3.9%, 4.0%, 4.1%, 4.2%, 4.3%, 4.4%, 4.5%, 4.6%, 4.7%, 4.8%, 4.9%, 5.0%, 5.1%, 5.2%, 5.3%, 5.4%, 5.5%, or 5.6%.

[0055] Optionally, in some embodiments, the distance L1 between the center z1 of the opening region 103 and the center z2 of the sub-pixel opening 12a is between 0.3 micrometers and 0.8 micrometers.

[0056] Optionally, the distance L1 between the center z1 of the opening region 103 and the center z2 of the sub-pixel opening 12a can be 0.3 micrometers, 0.4 micrometers, 0.5 micrometers, 0.6 micrometers, 0.7 micrometers or 0.8 micrometers.

[0057] It should be noted that, in the present application embodiment, the display panel 10 of the display system 100 is described with the example of the opposing substrate 12 being offset to the right relative to the array substrate 11, and the corresponding light pattern is described accordingly.

[0058] Please refer to Figure 2, which shows a schematic view of the opposing substrate 12 offset to the right relative to the array substrate 11. The rightward offset of the opposing substrate 12 causes the center z1 of the opening region 103 and the center z2 of the sub-pixel opening 12a to be offset relative to each other, forming an offset distance L1.

[0059] Please refer to Figure 5. In Figure 5, part 5a shows the light pattern with an offset distance L1 between 0.3 micrometers and 0.5 micrometers (inclusive). Part 5b shows the light pattern with an offset distance L1 between 0.5 micrometers and 0.8 micrometers (inclusive). Part 5c shows the light pattern with an offset distance L1 greater than 0.8 micrometers.

[0060] As shown in parts 5a and 5b of Figure 5, the brightness of the light emitted from the display panel 10 at a wide viewing angle has been improved, and the brightness at a wide viewing angle with a larger offset is better. As shown in part 5c of Figure 5, when the offset distance L1 is greater than 0.8 micrometers, the light pattern of the display panel 10 is cut off.

[0061] Please refer to Figure 6. Figure 6 shows the brightness decay curve corresponding to the light emission pattern of the display panel 10 when the offset distance L1 is equal to 0.5 micrometers. Compared with the existing brightness decay curve in Figure 4b, it can be seen from Figure 6 that the chief ray angle (CRA) of the display panel 10 is shifted to the right, and the brightness decay curve corresponding to Figure 6 is wider, which improves the utilization rate of large-angle light.

[0062] Optionally, in some embodiments of this application, in the thickness direction F3 of the display panel 10, a portion of one of the data line 101 and the scan line 102 is located within the sub-pixel opening 12a, and the black matrix layer 201 blocks a portion of the opening area 103.

[0063] In Figures 2 and 3, the first direction F1 is parallel to the extension direction of the scan line 102. The second direction F2 is parallel to the extension direction of the data line 101. Optionally, the first direction F1 is perpendicular to the second direction F2, but it is not limited to this. For example, the first direction F1 and the second direction F2 may not intersect perpendicularly.

[0064] In some embodiments, referring to FIG2, when the opposing substrate 12 is offset relative to the array substrate 11 along the first direction F1, the opposing substrate 12 is offset to the left or right. At this time, a portion of the data line 101 is located within the sub-pixel opening 12a, and the black matrix layer 201 blocks a portion of the opening area 103.

[0065] The black matrix layer 201 includes multiple first light-shielding portions b1 and multiple second light-shielding portions b2. The first light-shielding portions b1 extend along a first direction F1, and the second light-shielding portions b2 extend along a second direction F2. The multiple first light-shielding portions b1 and the multiple second light-shielding portions b2 are intersected to form multiple sub-pixel openings 12a.

[0066] The first light-shielding part b1 fully covers the scan line 102. In the first direction F1, the second light-shielding part b2 covers a portion of the data line 101, and the sub-pixel opening 12a exposes a portion of the data line 101.

[0067] In some embodiments, referring to FIG3, when the opposing substrate 12 is offset relative to the array substrate 11 along the second direction F2, the opposing substrate 12 is offset vertically. At this time, a portion of the scan line 102 is located within the sub-pixel opening 12a, and the black matrix layer 201 blocks a portion of the opening region 103.

[0068] The difference from the embodiment corresponding to FIG7 is that FIG8 shows the opposing substrate 12 being offset vertically. Therefore, in the second direction F2, the first light-shielding part b1 covers a portion of the scan line 102, and the sub-pixel opening 12a exposes a portion of the scan line 102. The second light-shielding part b2 fully covers the data line 101.

[0069] Optionally, in some embodiments of this application, the array substrate 11 further includes a pixel electrode 111, which is disposed within an opening region 103. In a first direction F1 or a second direction of the top viewing angle of the display panel 10, the black matrix layer 201 covers a portion of the pixel electrode 111.

[0070] Understandably, as the demand for brightness at wide viewing angles increases, the offset distance L1 will also increase, causing the black matrix layer 201 to cover a portion of the pixel electrode 111.

[0071] Optionally, the liquid crystal driving architecture of the display panel 10 can be a driving architecture based on fringe field switching (FFS) technology, a driving architecture based on in-plane switching (IPS) technology, or a driving architecture based on vertical alignment (VA) technology, etc.

[0072] Please refer to Figure 7, which shows a schematic structural view of the array substrate 11 of the display panel 10. The array substrate 11 includes a substrate 112, thin-film transistors 116, a planarization layer 113, a passivation layer 114, and a common electrode 115. The thin-film transistors 116 are disposed on the substrate 112, the planarization layer 113 covers the thin-film transistors 116, and pixel electrodes 111 are disposed on the planarization layer 113 and connected to the thin-film transistors 116. The passivation layer 114 covers the pixel electrodes 111, and the common electrode 115 is disposed on the passivation layer 114.

[0073] It should be understood that the array substrate 11 of the display panel 10 can also be other structures, which will not be elaborated here.

[0074] Additionally, it should be noted that the color filter layer (not shown in the figure) can be formed on the opposing substrate 12 or on the array substrate 11, and this embodiment does not impose any limitations.

[0075] Optionally, referring to Figure 1, in some embodiments of this application, the reflecting component 20 includes a first reflecting mirror 21, a second reflecting mirror 22, and a reflecting member 23. The first reflecting mirror 21 is configured to reflect the image source to the second reflecting mirror 22. The second reflecting mirror 22 is configured to receive the image source reflected by the first reflecting mirror 21 and project the image source onto the reflecting member 23. The reflecting member 23 is configured to reflect the image source to the human eye to form a virtual image xx.

[0076] Among them, the reflective component 23 can be a transparent-reflective component. For example, when the display system 100 of this application embodiment is applied to a car, the reflective component 23 can include the windshield component of the car; when the display system 100 of this application embodiment is applied to a VR device, the reflective component 23 can include a window.

[0077] It should be noted that the specific architecture of the reflective component 20 is not limited to the above-described embodiments. For example, the reflective component 20 may include only one reflector, or it may include two reflectors, or it may include three or more reflectors, and so on.

[0078] Optionally, in some embodiments of this application, the reflecting surfaces of the first reflector 21 and the second reflector 22 are both curved surfaces.

[0079] The first reflector 21 and the second reflector 22 are designed with curved surfaces to form a double free-form off-axis three-reflection system. This system can precisely control the position and angle of the virtual image surface, ensuring that the driver can easily obtain the required information at different distances. This system design can provide virtual images at different distances, such as virtual image surfaces at 10 meters, 7.5 meters, and 3.5 meters, with each virtual image surface corresponding to different visual needs.

[0080] Optionally, in some embodiments of this application, the display system 100 has a main optical axis g1. In the side view of the display system 100 (as shown in FIG1), the virtual line g2 connecting the center of the reflective member 23 and the center of the virtual image xx is collinear with the main optical axis g1, and the plane on which the display panel 10 is located is parallel to the main optical axis g1.

[0081] It should be noted that the main ray axis g1 is within the luminous viewing angle range of the display system 100 and is the direction of the ray along the virtual line g2 connecting the center of the reflective component 23 and the center of the virtual image xx. The human eye has the optimal viewing angle when positioned within the main ray axis g1.

[0082] The plane on which the display panel 10 is located is parallel to the main light axis g1, which allows the display panel 10 to be set horizontally in the vehicle head-up display scenario without tilting it, greatly reducing the difficulty of installation and shrinking the installation space in the vertical direction.

[0083] Figure 8 illustrates a display system 100 according to one or more embodiments of this application. In Figure 8, parts that differ from those in the above embodiments will be described to avoid redundancy.

[0084] Referring to Figure 8, the plane where the backlight module 30 is located intersects with the plane where the display panel 10 is located.

[0085] In other words, compared to the display system 100 of the embodiment corresponding to FIG1, the embodiment corresponding to FIG8 adopts a backlight module 30 that is tilted to the display panel 10.

[0086] Understandably, the offset setting of the array substrate 11 and the opposing substrate 12 in the display panel 10 increases the light output brightness over a wide viewing angle. Therefore, by tilting the backlight module 30, most of the light from the backlight module 30 can pass through the light output channel 301 of the display panel 10, thereby improving the overall display brightness.

[0087] Optionally, in some embodiments of this application, the angle α1 between the plane where the backlight module 30 is located and the plane where the display panel 10 is located is between 10 degrees and 40 degrees.

[0088] It is important to understand that the larger the included angle a1, the greater the tilt of the backlight module 30, and the greater the offset of the main beam angle of the backlight module 30. In order to match the main beam angle of the backlight module 30 with the light emission channel 301 of the display panel 10 to achieve a better light emission effect, the included angle a1 can be selected between 10 degrees and 40 degrees, such as 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees or 40 degrees.

[0089] It should be explained that, for the display system 100, the size of the included angle a1 directly affects the light emission pattern of the display panel 10, and the tilt setting of the backlight module 30 is beneficial to optimizing the light emission pattern of the display panel 10 to match the main beam angle of the display system, so as to make the brightness uniformity at eye level better.

[0090] Referring to Figure 9, this application embodiment also provides a display device 1000, which includes the display system 100 as described in any of the above embodiments.

[0091] It should be noted that the structure of the display system 100 of the display device 1000 in this application embodiment is similar to or the same as the structure of the display system 100 in any of the above embodiments, so it will not be described again here.

[0092] Optionally, the display device 1000 can be a VR device or an in-vehicle display device, but is not limited to these.

[0093] The display device 1000 of this application embodiment offsets the array substrate 11 and the opposing substrate 12 of the display panel 10 in the display system 100, so that in the top view of each light emission channel 301 of the display panel 10, the center of the opening area 103 is offset relative to the center of the sub-pixel opening 12a, thereby improving the light emission pattern of the display panel 10. The light emission CRA angle of the display panel 10 is improved, so that the light emission pattern of the display panel 10 matches the main ray angle required by the display device 1000, thereby improving the light transmittance of the display device 1000, improving the problem of large-angle color shift, and realizing a VR display with high transmittance and high brightness.

[0094] The above provides a detailed description of a display system and display device provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
