Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, the various embodiments can be combined with each other but will not be repeated one by one, and in the absence of contrary instructions, the directional words used, such as "upper" and "lower", usually refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the drawings; while "inside" and "outside" refer to the outline of the device; the terms "first", "second", "third", etc. are used only as markings, and no numerical requirements are imposed or order is established.

[0036] The embodiments of the present application provide a display system and a display device, which are described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0037] Please refer to Figure 1 An embodiment of the present application provides a display system 100 , which includes a display panel 10 and a reflective component 20 .

[0038] The display panel 10 is configured to output an image source, and the reflective component 20 is configured to receive the image source and project it to human eyes to form a virtual image xx.

[0039] The display system 100 further includes a backlight module 30 that provides a surface light source for the display panel 10. The display panel 10 is located at the light emitting side of the backlight module 30. The plane where the backlight module 30 is located is parallel to the plane where the display panel 10 is located.

[0040] It can be understood that the plane where the display panel 10 is located is the plane where the substrate of the display panel 10 is located, and the plane where the backlight module 30 is located is the plane where the back plate of the backlight module 30 is located. The plane where the backlight module 30 is located is parallel to the plane where the display panel 10 is located, so that the backlight module 30 and the display panel 10 are equidistantly arranged, saving assembly space.

[0041] Optionally, in the display system 100 of some embodiments of the present application, please refer to Figure 2 and Figure 3 The display panel 10 includes an array substrate 11 and an opposing substrate 12 that are arranged opposite to each other. The array substrate 11 includes data lines 101 and scan lines 102, and the data lines 101 and the scan lines 102 are arranged to cross each other to form a plurality of opening areas 103. The opposing substrate 12 includes a black matrix layer 201, and a plurality of sub-pixel openings 12a are formed on the black matrix layer 201. In the thickness direction F3 of the display panel 10, a sub-pixel opening 12a and an opening area 103 are arranged correspondingly to form a light outlet channel 301.

[0042] In the top view of each light outlet 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 12 a .

[0043] It should be noted that the array substrate 11 and the counter substrate 12 may be offset in a direction parallel to the scanning line 102 based on the array substrate 11 and the counter substrate 12 being offset left and right, such as Figure 2 As shown; it can also be based on the array substrate 11, the opposite substrate 12 is offset up and down along the direction parallel to the data line 101, such as Figure 3 As shown; it can also be based on the array substrate 11, the counter substrate 12 is first shifted left and right, then shifted up and down, etc. In some embodiments, the array substrate 11 can also be moved based on the counter substrate 12.

[0044] It should be explained that in the existing display panels, the array substrate and the color filter substrate are arranged opposite to each other, that is, in the thickness direction of the display panel, the center of the opening area of ​​the array substrate is opposite to the center of the sub-pixel opening on the black matrix of the color filter substrate, so that the luminous brightness at the normal viewing angle is maximized. However, when the existing display panel is applied to the optical display system, because the imaging quality is related to the chief ray angle (CRA, Chief Ray Angle) of the optical machine and the light type of the display panel, in order to maximize the light emission effect, when the chief ray angle of the optical machine is fixed, due to the light emission light type (such as Figure 4a) and brightness attenuation curves (as shown Figure 4b As shown in the figure, the light output brightness at a large viewing angle is small, which can easily cause display color deviation.

[0045] The display system 100 of the embodiment of the present application offsets the array substrate 11 and the opposing substrate 12 of the display panel 10 so that in the top-view angle of each light output 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 output pattern of the display panel 10, widening the brightness attenuation curve, and increasing the light output brightness at a large angle to improve color deviation.

[0046] Optionally, in some embodiments of the present application, in a top-down perspective of each light output 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 a percentage of the width of the sub-pixel opening 12a ranging from 1.4% to 5.6%.

[0047] It can be understood 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 distance between the opening area 103 and the sub-pixel opening 12a. The distance L1 is related to the size of the sub-pixel opening 12a. The larger the distance L1 occupies the width of the sub-pixel opening 12a, the larger the relative offset distance between the opening area 103 and the sub-pixel opening 12a, and vice versa. 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 distance between the opening area 103 and the sub-pixel opening 12a. When the distance L1 is too large, the light pattern of the display panel will be cut; when the distance L1 is too small, the effect of improving the light output brightness at a large viewing angle is limited. Therefore, in order to ensure that the light output brightness at a large viewing angle is improved to better improve the color deviation, 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 and the width of the sub-pixel opening 12a is selected to be between 1.4% and 5.6%.

[0048] 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 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%.

[0049] Optionally, in some embodiments, the distance L1 between the center z1 of the opening area 103 and the center z2 of the sub-pixel opening 12 a is between 0.3 micrometers and 0.8 micrometers.

[0050] Optionally, the distance L1 between the center z1 of the opening area 103 and the center z2 of the sub-pixel opening 12 a may be 0.3 micrometers, 0.4 micrometers, 0.5 micrometers, 0.6 micrometers, 0.7 micrometers or 0.8 micrometers.

[0051] It should be noted that the display panel 10 of the display system 100 in the embodiment of the present application takes the case where the opposing substrate 12 is offset to the right relative to the array substrate 11 as an example to illustrate the corresponding light pattern.

[0052] Please refer to Figure 2 , Figure 2 The diagram shows a schematic diagram of the counter substrate 12 shifting to the right relative to the array substrate 11. The rightward shift of the counter substrate 12 causes the center z1 of the opening area 103 and the center z2 of the sub-pixel opening 12a to shift relative to each other, forming a shift distance L1.

[0053] Please refer to Figure 5 ,exist Figure 5 In the figure, part 5a shows a light pattern with an offset distance L1 between 0.3 micrometers and 0.5 micrometers (including 0.5 micrometers). Part 5b shows a light pattern with an offset distance L1 between 0.5 micrometers and 0.8 micrometers (including 0.8 micrometers). Part 5c shows a light pattern with an offset distance L1 greater than 0.8 micrometers.

[0054] Depend on Figure 5 As can be seen from parts 5a and 5b, the brightness of the light emitted from the display panel 10 at a large viewing angle is improved, and the brightness at a large viewing angle with a larger offset is better; Figure 5 As can be seen from part 5c, when the offset distance L1 is greater than 0.8 micrometers, the light pattern of the display panel 10 is cut.

[0055] Please refer to Figure 6 , Figure 6 is the brightness attenuation curve corresponding to the light emission pattern of the display panel 10 when the offset distance L1 is equal to 0.5 micrometers. Figure 4b The existing brightness attenuation curve is based on Figure 6 It can be seen that the chief ray angle (CRA) of the display panel 10 is shifted to the right. Figure 6 The corresponding brightness attenuation curve is wider, and the utilization rate of large-angle light is improved.

[0056] Optionally, in some embodiments of the present 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 12 a , and the black matrix layer 201 blocks a portion of the opening area 103 .

[0057] exist Figure 2 and Figure 3 In the embodiment, 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 is not limited thereto. For example, the first direction F1 and the second direction F2 do not intersect perpendicularly.

[0058] In some embodiments, please refer to Figure 2 When the counter substrate 12 is offset relative to the array substrate 11 along the first direction F1, the counter substrate 12 is offset left and right. At this time, a part of the data line 101 is located in the sub-pixel opening 12a, and the black matrix layer 201 blocks a part of the opening area 103 .

[0059] The black matrix layer 201 includes a plurality of first light shielding portions b1 and a plurality of second light shielding portions b2. The first light shielding portions b1 extend along the first direction F1, and the second light shielding portions b2 extend along the second direction F2. The plurality of first light shielding portions b1 and the plurality of second light shielding portions b2 are cross-connected to form a plurality of sub-pixel openings 12a.

[0060] The first light shielding portion b1 completely covers the scan line 102. In the first direction F1, the second light shielding portion b2 covers a portion of the data line 101, and the sub-pixel opening 12a exposes a portion of the data line 101.

[0061] In some embodiments, please refer to Figure 3 When the counter substrate 12 is offset relative to the array substrate 11 along the second direction F2, the counter substrate 12 is offset up and down. At this time, part of the scanning line 102 is located in the sub-pixel opening 12a, and the black matrix layer 201 blocks part of the opening area 103.

[0062] and Figure 7 The difference of the corresponding embodiments is that Figure 8 To shift the opposing substrate 12 up and down, in the second direction F2 , the first light shielding portion b1 covers a portion of the scanning line 102 , and the sub-pixel opening 12 a exposes a portion of the scanning line 102 . The second light shielding portion b2 completely covers the data line 101 .

[0063] Optionally, in some embodiments of the present application, the array substrate 11 further includes a pixel electrode 111, and a pixel electrode 111 is correspondingly disposed in an opening area 103. In the first direction F1 or the second direction of the top view of the display panel 10, the black matrix layer 201 covers a portion of the pixel electrode 111.

[0064] It is understandable that as the demand for high viewing angle brightness increases, the offset distance L1 will also increase, so that the black matrix layer 201 covers a portion of the pixel electrode 111 .

[0065] Optionally, the liquid crystal driving architecture of the display panel 10 can be based on a fringe field switching (FFS) technology driving architecture, an in-plane switching (IPS) technology driving architecture, a vertical alignment (VA) technology driving architecture, and so on.

[0066] Please refer to Figure 7 , Figure 7 The schematic structural view of the array substrate 11 of the display panel 10 is shown. The array substrate 11 includes a substrate 112, a thin film transistor 116, a planar layer 113, a passivation layer 114, and a common electrode 115. The thin film transistor 116 is disposed on the substrate 112, the planar layer 113 covers the thin film transistor 116, the pixel electrode 111 is disposed on the planar layer 113 and connected to the thin film transistor 116. The passivation layer 114 covers the pixel electrode 111, and the common electrode 115 is disposed on the passivation layer 114.

[0067] It should be understood that the array substrate 11 of the display panel 10 may also have other structures, which will not be described in detail here.

[0068] In addition, 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 of the present application does not limit this.

[0069] Optional, please continue to refer to Figure 1In some embodiments of the present application, the reflection assembly 20 includes a first reflection mirror 21, a second reflection mirror 22 and a reflection component 23. The first reflection mirror 21 is configured to reflect the image source to the second reflection mirror 22. The second reflection mirror 22 is configured to receive the image source reflected by the first reflection mirror 21 and project the image source to the reflection component 23. The reflection component 23 is configured to reflect the image source to the human eye to form a virtual image xx.

[0070] Among them, the reflective component 23 can be a transflective component. For example, when the display system 100 of the embodiment of the present application is applied to a car, the reflective component 23 may include a front windshield component of the car; when the display system 100 of the embodiment of the present application is applied to a VR device, the reflective component 23 may include a window.

[0071] It should be noted that the specific structure of the reflective component 20 is not limited to the above-mentioned embodiment. For example, the reflective component 20 may include only one reflector, two reflectors, or more than three reflectors, and so on.

[0072] Optionally, in some embodiments of the present application, the reflective surfaces of the first reflector 21 and the second reflector 22 are both curved surfaces.

[0073] The first reflector 21 and the second reflector 22 are designed with curved surfaces to form a double free-surface off-axis three-reflection system, which can accurately control the position and angle of the virtual image plane to ensure 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 planes of 10 meters, 7.5 meters, and 3.5 meters, and each virtual image plane corresponds to different visual requirements.

[0074] Optionally, in some embodiments of the present application, the display system 100 has a main optical axis g1. Figure 1 As shown), a 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 a plane where the display panel 10 is located is parallel to the main optical axis g1.

[0075] It should be noted that the principal ray axis g1 is within the luminous viewing angle range of the display system 100 and coincides with the direction of the virtual line g2 connecting the center of the reflective component 23 and the center of the virtual image xx. When the human eye is located in the principal ray axis g1, the human eye has the best viewing angle.

[0076] The plane where the display panel 10 is located is parallel to the main optical axis g1, so that in the vehicle-mounted head-up display scene, the display panel 10 can be set horizontally without being tilted, which greatly reduces the difficulty of installation and reduces the installation space in the vertical direction.

[0077] Figure 8 The display system 100 of one or more embodiments of the present application is shown. Figure 8 In the present invention, parts different from those of the above-described embodiment will be described to avoid redundancy.

[0078] Reference Figure 8 , the plane where the backlight module 30 is located intersects with the plane where the display panel 10 is located.

[0079] That is to say, compared to Figure 1 The display system 100 of the corresponding embodiment, Figure 8 In the corresponding embodiment, the backlight module 30 is disposed in a manner that is inclined with respect to the display panel 10 .

[0080] It is understandable that the light output brightness at a large viewing angle is increased based on the offset setting of the array substrate 11 and the opposing substrate 12 in the display panel 10. Therefore, the backlight module 30 is tilted so that 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.

[0081] Optionally, in some embodiments of the present application, an angle a1 between a plane where the backlight module 30 is located and a plane where the display panel 10 is located is between 10 degrees and 40 degrees.

[0082] It should be understood that the larger the angle a1 is, the greater the tilt of the backlight module 30 is, and the greater the deviation of the main light angle of the backlight module 30 is. In order to make the main light angle of the backlight module 30 match the light outlet channel 301 of the display panel 10 to achieve a better light outlet effect, the angle a1 can be selected to be between 10 degrees and 40 degrees, for example, 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees or 40 degrees.

[0083] It should be explained that, for the display system 100, the size of the angle a1 directly affects the light pattern of the display panel 10, and the inclined setting of the backlight module 30 is beneficial to optimizing the light pattern of the display panel 10 to match the main light angle of the display system, so that the brightness uniformity is better.

[0084] Please refer to Fig. 9 , an embodiment of the present application further provides a display device 1000, which includes the display system 100 as described in any one of the above embodiments.

[0085] It should be noted that the structure of the display system 100 of the display device 1000 of the embodiment of the present application is similar to or the same as the structure of the display system 100 of any of the above embodiments, so it is not repeated here.

[0086] Optionally, the display device 1000 may be a VR device or a vehicle-mounted display device, but is not limited thereto.

[0087] The display device 1000 of the embodiment of the present application 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 angle of each light output 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 to improve the light output pattern of the display panel 10. The light output CRA angle of the display panel 10 is improved so that the light output pattern of the display panel 10 matches the principal 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 deviation, and achieving high-transmittance and high-brightness VR display.

[0088] The above is a detailed introduction to a display system and a display device provided in an embodiment of the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
