Background Art

[0002] A head-up display (HUD) is an aircraft flight aid that was initially used in aircraft. At present, HUDs are widely applied to automobiles, and its principle is that the image on the display is reflected by one or two mirrors and projected onto the front windshield of the automobile to form a high-brightness virtual image in front of a person's eyes.

[0003] Affected by the distance between a person's eyes and the virtual image and the size of the display, the larger the viewing angle, the lower the brightness of the peripheral area of the display image visible to a person's eyes. That is, the brightness of the middle area of the display image visible to a person's eyes is bright, and the brightness of the peripheral area of the display image visible to a person's eyes gradually becomes darker. Therefore, how to improve the brightness uniformity of the display image visible to the human eye is an urgent problem that must be solved.

[0029] Each embodiment provided in this application is similar, and features in different embodiments are combined with each other.

[0030] As shown in Figure 1, an embodiment of the present invention provides a display module. The display module 100 includes a light-emitting functional layer 10 and a plurality of dimming units 20, the light-emitting functional layer 10 includes a substrate 11 and a plurality of light-emitting units 12, the plurality of light-emitting units 12 are arranged in an array on the substrate 11, the light-emitting functional layer 10 includes a central display area A1 and two peripheral display areas, and in the light-emitting functional layer 10, the peripheral display area A2, the central display area A1 and the peripheral display area A2 are arranged sequentially in the first direction X. The plurality of light-emitting units 12 include a first light-emitting unit 121 located in the central display area A1 and a second light-emitting unit 122 located in the peripheral display area A2. The plurality of dimming units 20 are arranged on the light-emitting surface side of the light-emitting functional layer 10 and include a first dimming unit 21 and a second dimming unit 22, the first dimming unit 21 corresponds to the first light-emitting unit 121 and the second dimming unit 22 corresponds to the second light-emitting unit 122. In the plane on which the light-emitting functional layer 10 is located, the light-emitting functional layer 10 has a center line perpendicular to the first direction X. The main optical axis of the first light-emitting unit 121 coincides with the main optical axis of the first light-emitting unit 121 after the main optical axis of the first light-emitting unit 121 has passed through the first light-adjusting unit 21. The main optical axis of the second light-emitting unit 122 after the main optical axis of the second light-emitting unit 122 is positioned close to the center line with respect to the main optical axis of the second light-emitting unit.

[0031] In the display module of the present invention, the dimming main optical axis of the first light-emitting unit 121 overlaps with the dimming main optical axis of the first light-emitting unit 121 after it has passed through the first dimming unit 21. The dimming main optical axis of the second light-emitting unit 122 after it has passed through the second dimming unit 22 is positioned close to the center line with respect to the main optical axis of the second light-emitting unit 122. As a result, in the narrow viewing angle range, the brightness at a viewing angle of 10° is about 65% of the brightness at a viewing angle of 0° compared to a light-emitting functional layer without a dimming unit, and the brightness uniformity of the light-emitting functional layer is greatly improved by the light-emitting functional layer with a dimming unit installed. Overall brightness is also improved, and the display brightness of the peripheral display area in the narrow viewing angle range becomes 90% or more of the display brightness of the central display area.

[0032] In embodiments of the present invention, the display module is referred to as a HUD display module or head-up display module applied to an automobile. A head-up display (HUD) is a device that projects meter information (such as speed) and navigation information in front of the driver's field of vision. This allows the driver to see meter information and navigation information in front of their field of vision, eliminating the need to look down at the dashboard or center display below the steering wheel. This improves emergency braking reaction time and enhances driving safety.

[0033] In embodiments of the present invention, the first dimming unit 21 includes a first lens 21, and the second dimming unit 22 includes a second lens 22, and the first lens 21 and the second lens 22 have the same structure and may be conventional convex lenses. The plurality of light-emitting units 12 include a first group of light-emitting units and a second group of light-emitting units. The first group of light-emitting units includes a plurality of first light-emitting units 121 arranged at intervals in the second direction Y. The second group of light-emitting units includes a plurality of second light-emitting units 122 arranged at intervals in the second direction Y. The peripheral display area A2 includes a plurality of second groups of light-emitting units arranged sequentially along the first direction X. The second direction Y is perpendicular to the first direction X. Here, the first direction X is the width direction of the light-emitting functional layer, and the second direction Y is the longitudinal direction of the light-emitting functional layer.

[0034] Here, if we consider the offset interval w in the first direction X, where the center of the second lens 22 is shifted toward the center line L1 relative to the principal optical axis of the second light-emitting unit 122, then in the same group of second light-emitting units, the corresponding principal optical axes of multiple second light-emitting units 122 have the same offset interval w relative to the center of the second lens 22.

[0035] In the first direction X, any two groups of the second light-emitting units are included, and the offset interval w of the second light-emitting unit 122 in the group of second light-emitting units that is farther from the central display area A1 is greater than the offset interval w of the second light-emitting unit in another group of second light-emitting units that is closer to the central display area A1.

[0036] In this embodiment, the first lens 21 and the first light-emitting unit 121 are provided in a one-to-one correspondence, and the second lens 22 and the second light-emitting unit 122 are provided in a one-to-one correspondence. That is, the orthographic projection of the first lens 21 onto the substrate 11 covers the orthographic projection of one first light-emitting unit 121 onto the substrate 11. The orthographic projection of the second lens 22 onto the substrate 11 covers the orthographic projection of one second light-emitting unit 121 onto the substrate 11. The orthographic projection of the principal optical axis of the second lens 22 onto the substrate 11 is located closer to the center line L1 than the orthographic projection of the principal optical axis of the second light-emitting unit 122 onto the substrate 11.

[0037] In embodiments of the present invention, the central display area A1 includes at least one group of first light-emitting units. Specifically, if the resolution of the light-emitting functional layer 10 is W*H, then the light-emitting functional layer 10 includes W rows of light-emitting units 12 spaced apart in the second direction Y, and H columns of light-emitting units 12 spaced apart in the first direction X. Here, if H is an odd number, the central display area A1 includes an odd number of groups of first light-emitting units, for example, one group of first light-emitting units, or three groups of first light-emitting units, or five groups of first light-emitting units, or seven groups of first light-emitting units, or nine groups of first light-emitting units, ... Preferably, the central display area A1 includes one group of first light-emitting units. When H is an even number, the central display area A1 includes an even number of first light-emitting unit groups, for example, two first light-emitting unit groups, or four first light-emitting unit groups, or six first light-emitting unit groups, or eight first light-emitting unit groups, or ten first light-emitting unit groups, ... Preferably, the central display area A1 includes two first light-emitting unit groups.

[0038] In embodiments of the present invention, two peripheral display areas A2 include a first display area and a second display area, and a central display area A1 is located between the first and second display areas. A plurality of second light-emitting units 121 located in the first display area and a plurality of second light-emitting units located in the second display area are mirror-image symmetric with respect to the center line L1. The distribution of the offset angle between the dimming principal optical axis emitted from the second lens 22 located on both sides of the center line L1 and the principal optical axis of the second light-emitting unit 122 corresponding to the second lens is arranged in a mirror-image symmetric with respect to the center line L1.

[0039] In embodiments of the present invention, the peripheral display area A2 includes a plurality of groups of second light-emitting units arranged at intervals in the first direction X. Here, the offset interval w of the plurality of second light-emitting units 121 located in the same group of second light-emitting units is equal.

[0040] In the embodiment of the present invention, in the first direction X, the offset interval w is larger for the second light-emitting unit 122 that is further from the central display area A1.

[0041] In embodiments of the present invention, for example, if the pitch of one group of light-emitting units is 200 μm and the diameter of the corresponding lens 20 is 200 μm (radius 100 μm), then in the first direction X, the offset interval w of the multiple second light-emitting units 121 in the second group of light-emitting units adjacent to the central display area A1 is between 1.5 μm and 2.5 μm, preferably 2 μm. When the angle between the light emitted from the first light-emitting unit 121 and the vertical central axis of the lens 20 after it has passed through the lens 20 is 0 degrees, then the angle between the light emitted from the second light-emitting unit 121 and the vertical central axis of the lens 20 after it has passed through the lens 20 is between 0.5 degrees and 1.5 degrees, and if the pitch is 2 μm, the angle of the light is 1 degree. The difference between the offset interval w of multiple second light-emitting units 121 within the k-th second light-emitting unit group, which is arranged away from the central display area A1, and the offset interval w of multiple second light-emitting units 121 within the (k-1)-th second light-emitting unit group is 2 μm. Specifically, the pitch value can be adjusted to match the actual screen resolution, and the pitch value ranges from 2 nm to 20,000 nm.

[0042] In the embodiment of the present invention, the offset distance that brings the center of the orthographic projection of the k-th second light-emitting unit group, which is positioned away from the central display area A1, onto the substrate, closer to the center line in the first direction of the orthographic projection of the second lens onto the substrate is determined by the following formula. w = a / (m / 2)*(k-1)

[0043] Here, the target interval at which the dimming main optical axis of the second light-emitting unit 122 in the second light-emitting unit group furthest from the central display area A1 approaches the center line in the first direction X is a, the total number of light-emitting units 12 arranged at intervals in the first direction X on the light-emitting functional layer 10 is m, and k is the kth second light-emitting unit group arranged in the direction away from the central display area A1.

[0044] For example, if the width of the light-emitting functional layer 10 is 200 μm, and the total number m of light-emitting units 12 arranged in the first direction X on the light-emitting functional layer 10 is 650 (sum of the first and second light-emitting unit groups), and the target spacing a of the second light-emitting unit 121 of the second light-emitting unit group furthest from the central display area A1 is 5 μm according to the simulation results, then the offset spacing w of the second light-emitting unit 121 of the second (k is 2) second light-emitting unit group arranged in the direction away from the central display area A1 is 5 μm. Generally, the value of a / (m / 2) is between 2nm and 1000nm. For example, the value of a / (m / 2) includes 2nm, 3nm, 5nm, 10nm, 15nm, 20nm, 25nm, 30nm, ... 100nm, 200nm, ... 500nm, 600nm, ... 800nm, 900nm, 1000nm, etc.

[0045] In embodiments of the present invention, the shape of the lens 20 includes at least one of the following: columnar, rotary table, conical, and trapezoidal.

[0046] In the embodiments of this application, the display module further includes an optical imaging unit for propagating light emitted through the light-emitting functional layer 10 to the windshield, and the reverse extension of the light after it has been reflected through the windshield forms a virtual image at a first predetermined position. The larger the angle between the eye box and the field of view around the virtual image, the larger the offset spacing w of the second light-emitting unit 121 away from the central display area A1, and the eye box is the area where the driver's eyes are located.

[0047] As shown in Figure 2a, in conventional display modules, the light emitted through the first lens 21 and the light emitted through the second lens 22 are parallel light. After being reflected by the windshield, they are emitted parallel to the direction of the human eye. As a result, the brightness of the central display area of ​​the display image seen by the human eye is bright, and the brightness of the peripheral display area seen by the human eye gradually decreases.

[0048] As shown in Figure 2b, in the display module provided in the embodiment of the present invention, after the second light-emitting unit 121 shifts away from the central display area, the angle of the light emitted through the second lens 22 changes (it is emitted in the direction of the central axis of the second lens 22), and after being reflected by the windshield, it converges in the direction of the light emitted through the first lens 21, so that the brightness of the central display area and the peripheral display area of ​​the display image visible to the human eye matches.

[0049] As shown in Figure 3a, the display brightness of the display image visible to the human eye in a conventional display module is 120 candelas / m² for the central display area A1. 2 ~140 candela / m 2 In this case, the display brightness of the peripheral display area A2 (in this example, the display brightness corresponding to ±10°) is 80 candelas / m². 2 ~95 candela / m 2 Therefore, the difference between the display brightness of the central display area A1 and the display brightness of the peripheral display area A2 is large (the display brightness of the peripheral display area A2 is 65% or less of the display brightness of the central display area A1), resulting in poor uniformity of brightness in the display image visible to the human eye.

[0050] As shown in Figure 3b, after shifting the second light-emitting unit 121 within the light-emitting unit 12 located in the peripheral display area A2 toward the central display area A1, the display brightness of the central display area A1 becomes 120 candelas / m². 2 ~140 candela / m 2 In this case, the display brightness of peripheral display area A2 (corresponding to the display brightness at a horizontal viewing angle of ±10° in the example) is 120 candelas / m². 2 ~140 candela / m 2 Therefore, the difference between the display brightness of the central display area A1 and the display brightness of the peripheral display area A2 becomes smaller, and the brightness of the peripheral display area and the brightness of the central area of ​​the visible display image become the same (the display brightness of the peripheral display area A2 is 90% or more of the display brightness of the central display area A1), improving the uniformity of the brightness of the display image visible to the human eye.

[0051] As shown in Figure 4, the embodiment of this application provides a display module 200. The difference between the display module 200 and the display module 100 is that the peripheral display area A2 in the display module 200 includes a first display area and a second display area arranged at intervals in the first direction X, and the central display area A1 is located between the first display area and the second display area. Both the first display area and the second display area include a plurality of sub-display areas A21 arranged at intervals in the first direction X. Each of the plurality of sub-display areas A21 is provided with N groups of second light-emitting units. That is, the number of second light-emitting unit groups in each of the plurality of sub-display areas A21 is the same. Here, the offset interval w of the plurality of second light-emitting units 121 located in the same sub-display area A21 is the same. N is a positive integer of 2 or more, for example, N is 3, 4, 5, 6, 7, 8, 9, 10...15...20...25...30...50...100...

[0052] In the first direction, the offset interval w is larger for the second light-emitting unit 121 located in the sub-display area that is farther from the central display area.

[0053] In embodiments of the present invention, when N is odd, the offset interval w of multiple second light-emitting units 121 in the same sub-display area A21 is equal to the offset interval w of the second light-emitting unit 121 in the group of second light-emitting units located in the center of the sub-display area A21.

[0054] For example, sub-display area A21 is adjacent to central display area A1. That is, in the first direction X, the first sub-display area A21 includes five groups of second light-emitting units. The offset interval w of multiple second light-emitting units 121 among the five groups of second light-emitting units in this sub-display area A21 is equal to the offset interval w of the second light-emitting units 121 of the third group of second light-emitting units in this sub-display area A21, which is positioned away from central display area A1.

[0055] In the embodiment of the present invention, if the pitch of one group of light-emitting units is 200 μm and the diameter of the corresponding lens 20 is 200 μm (radius 100 μm), then the difference between the offset interval w of the multiple second light-emitting units 121 in the k-th second group of second light-emitting units arranged in a direction away from the central display area A1 and the offset interval w of the multiple second light-emitting units 121 in the (k-1)th second group of second light-emitting units is 2 μm. Furthermore, the offset interval w of the multiple second light-emitting units 121 in the sub-display area A21 adjacent to the central display area A1 is 6 μm.

[0056] In embodiments of the present invention, when N is an even number, the offset interval w of multiple second light-emitting units 121 in the same sub-display area A21 is equal to the average value of the offset interval w of the second light-emitting units 121 in the N groups of second light-emitting units in the sub-display area A21.

[0057] For example, sub-display area A21 is adjacent to central display area A1. That is, in the first direction X, the first sub-display area A21 includes six groups of second light-emitting units. The offset interval w of multiple second light-emitting units 121 among the six groups of second light-emitting units in this sub-display area A21 is equal to the average value of the offset interval w of the second light-emitting units 121 within the six groups of second light-emitting units in this sub-display area A21.

[0058] In the embodiment of the present invention, if the pitch of one group of light-emitting units is 200 μm and the diameter of the corresponding lens 20 is 200 μm (radius 100 μm), then the difference between the offset interval w of the multiple second light-emitting units 121 in the k-th second group of second light-emitting units arranged in a direction away from the central display area A1 and the offset interval w of the multiple second light-emitting units 121 in the (k-1)th second group of second light-emitting units is 2 μm. Furthermore, the offset interval w of the multiple second light-emitting units 121 in the sub-display area A21 adjacent to the central display area A1 is 7 μm.

[0059] Alternatively, if N is an even number, the offset interval w of multiple second light-emitting units 121 in the same sub-display area A21 is equal to the average value of the offset interval w of the second light-emitting units 121 in two groups of second light-emitting units located in the center of the sub-display area A21.

[0060] For example, sub-display area A21 is adjacent to central display area A1. That is, in the first direction X, the first sub-display area A21 includes six groups of second light-emitting units. Among the six groups of second light-emitting units in this sub-display area A21, the offset interval w of multiple second light-emitting units 121 is equal to the average value of the offset interval w of the second light-emitting units 121 of the third group of second light-emitting units, which is positioned away from central display area A1 in this sub-display area A21, and the offset interval w of the second light-emitting units 121 of the fourth group of second light-emitting units.

[0061] The display module 200 provided in the present invention reduces process accuracy by N times while increasing the offset step size by offsetting multiple second light-emitting units 121 within N second light-emitting unit groups at the same pitch. This avoids the phenomenon where process accuracy cannot be achieved when offsetting multiple second light-emitting units 121 within a single second light-emitting unit group because the offset interval w is too small, thereby reducing the difficulty of the process and improving the uniformity of the brightness of the display module.

[0062] As shown in Figures 5 and 6, an embodiment of the present invention provides a display module 300. The difference between the display module 300 and the display module 200 is that the number of second light-emitting unit groups is greater in the sub-display area A21 that is further from the central display area A1. That is, the number of second light-emitting unit groups in the multiple sub-display areas A21 along the direction away from the central display area A1 is not equal in any of them.

[0063] Specifically, the peripheral display area A2 of the display module 300 includes a first display area and a second display area. The central display area A1 is located between the first and second display areas. Both the first and second display areas include a plurality of sub-display areas A21 arranged away from the central display area A1. The first light-emitting unit group includes a plurality of first light-emitting units 121 arranged in the second direction Y. The second light-emitting unit group includes a plurality of second light-emitting units 122 arranged in the second direction Y. The first and second light-emitting unit groups are arranged along the first direction X.

[0064] Specifically, of the two adjacent sub-display areas A21 that move away from the central display area A1, the number of second light-emitting units in the sub-display area A21 that moves away from the central display area A1 is t greater than the number of second light-emitting units in the sub-display area A21 that moves closer to the central display area A1, where t is a positive integer greater than or equal to 1, for example, t is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10...

[0065] In the example shown in Figure 5, the number of second light-emitting units in the sub-display area A21 adjacent to the central display area A1 is 1, and the number of second light-emitting units in the sub-display area A21 adjacent to the central display area A1 in the direction away from the central display area A1 is 3.

[0066] In the example shown in Figure 6, the number of second light-emitting units in the multiple sub-display areas A21, which are arranged away from the central display area A1, may increase by one in each subsequent instance. For example, the number of second light-emitting units in the three sub-display areas A21, which are arranged away from the central display area A1, is shown to be 2, 3, and 4, respectively.

[0067] Furthermore, the number of second light-emitting units added to the multiple sub-display areas A21, which are arranged away from the central display area A1, is not equal. For example, if the number of added second light-emitting units is a multiple of 2, then the number of second light-emitting units in the three sub-display areas A21, which are arranged away from the central display area A1, will be 2, 4, and 8, respectively.

[0068] As shown in Figures 7-10, the embodiment of the present application provides a display module 400. The difference between the display module 400 and the display module 100 is that in the display module 400, the first light-emitting unit group corresponds to n1 first lenses 21, and the second light-emitting unit group corresponds to n2 second lenses 22, where n1 and n2 may or may not be equal, and both n1 and n2 are positive integers of 2 or more, for example, n1 is equal to 3, 4, 5, 6, 7, 8, 9, 10..., and n2 is equal to 3, 4, 5, 6, 7, 8, 9, 10.... That is, the first light-emitting unit group corresponds to at least two first lenses 21, and the second light-emitting unit group corresponds to at least two second lenses 22. The first light-emitting unit group includes a plurality of first light-emitting units 121 arranged in the second direction Y. The second light-emitting unit group includes a plurality of second light-emitting units 122 arranged in the second direction Y. The first group of light-emitting units and the second group of light-emitting units are arranged along the first direction X.

[0069] In the example shown in Figure 7, the first light-emitting unit group corresponds to two first lenses 21, and the second light-emitting unit group corresponds to two second lenses 22.

[0070] In the example shown in Figure 8, the first light-emitting unit group corresponds to two first lenses 21, and the second light-emitting unit group corresponds to three second lenses 22.

[0071] In embodiments of the present invention, the orthographic projection of the first lens 21 onto the substrate 11 covers the orthographic projection of m1 first light-emitting units 121 of the first light-emitting unit group onto the substrate 11, and the orthographic projection of the second lens 22 onto the substrate 11 covers the orthographic projection of the principal optical axes of m2 second light-emitting units 121 of the second light-emitting unit group onto the substrate 11. m1 and m2 may or may not be equal. m1 and m2 are positive integers of 2 or greater. For example, m1 may be 3, 4, 5, 6, 7, 8, 9, 10... and m2 may be 3, 4, 5, 6, 7, 8, 9, 10...

[0072] For example, the orthographic projection of the first lens 21 onto the substrate 11 covers the orthographic projections of the two first light-emitting units 121 of the first light-emitting unit group onto the substrate 11, and the orthographic projection of the second lens 22 onto the substrate 11 covers the orthographic projections of the principal optical axes of the two second light-emitting units 121 of the second light-emitting unit group onto the substrate 11.

[0073] For example, the orthographic projection of the first lens 21 onto the substrate 11 covers the orthographic projections of the two first light-emitting units 121 of the first light-emitting unit group onto the substrate 11, and the orthographic projection of the second lens 22 onto the substrate 11 covers the orthographic projections of the principal optical axes of the three second light-emitting units 121 of the second light-emitting unit group onto the substrate 11.

[0074] Specifically, the orthographic projection of the first lens 21 onto the substrate 11 covers the orthographic projection of two or more first light-emitting units 121 of the first light-emitting unit group onto the substrate 11, and the orthographic projection of the second lens 22 onto the substrate 11 covers the orthographic projection of the principal optical axes of two or more second light-emitting units 121 of the second light-emitting unit group onto the substrate 11.

[0075] As shown in Figure 9, an embodiment of the present invention provides a display module 500. The difference between the display module 500 and the display module 100 is that the first lens 21 of the display module 500 includes a first sub-lens 211 and a second sub-lens 212, the orthographic projection of the first sub-lens 211 onto the substrate 11 covers the orthographic projection of at least two first light-emitting units 121 in the first light-emitting unit group onto the substrate 11, and the orthographic projection of the second sub-lens 212 onto the substrate 11 covers the orthographic projection of one first light-emitting unit 121 in the first light-emitting unit group onto the substrate 11. and / or, the second lens 22 includes a third sub-lens 221 and a fourth sub-lens 222, wherein the orthographic projection of the third sub-lens 221 onto the substrate 11 covers the orthographic projections of at least two second light-emitting units 121 of the second light-emitting unit group onto the substrate 11, and the orthographic projection of the fourth sub-lens 222 onto the substrate 11 covers the orthographic projection of the principal optical axis of one second light-emitting unit 121 of the second light-emitting unit group onto the substrate.

[0076] In the example shown in Figure 9, the orthographic projection of the first sub-lens 211 onto the substrate 11 covers the orthographic projections of the two first light-emitting units 121 of the first light-emitting unit group onto the substrate 11, the orthographic projection of the second sub-lens 212 onto the substrate 11 covers the orthographic projection of one first light-emitting unit 121 of the first light-emitting unit group onto the substrate 11, the orthographic projection of the third sub-lens 221 onto the substrate 11 covers the orthographic projections of the principal optical axes of the two second light-emitting units 121 in the second light-emitting unit group onto the substrate 11, and the orthographic projection of the fourth sub-lens 222 onto the substrate 11 covers the orthographic projection of the principal optical axis of one second light-emitting unit 121 in the second light-emitting unit group onto the substrate 11.

[0077] As shown in Figure 10, an embodiment of the present invention provides a display module 600. The difference between the display module 600 and the display module 100 is that in the display module 600, multiple first light-emitting units 121 of the first light-emitting unit group correspond to one first lens 21, and multiple second light-emitting units 122 of the second light-emitting unit group correspond to one second lens 22. Specifically, the orthographic projection of the first lens 21 onto the substrate 11 covers the orthographic projection of the multiple first light-emitting units 121 of the first light-emitting unit group onto the substrate 11, and the orthographic projection of the second lens 22 onto the substrate 11 covers the orthographic projection of the principal optical axes of the multiple second light-emitting units 121 of the second light-emitting unit group onto the substrate 11.

[0078] Here, the shapes of the multiple first lenses 21 may be the same or different, the shapes of the multiple second lenses 22 may be the same or different, and the shapes of the first lens 21 and the second lens 22 may be the same or different.

[0079] As shown in Figure 11, an embodiment of the present invention provides a display module 700. The difference between the display module 700 and the display module 100 is that the first lens 21 of the display module 700 is arranged in a one-to-one correspondence with the first light-emitting unit 121, and the second lens 22 is arranged in a one-to-one correspondence with the second light-emitting unit 122. The positions of the vector vertex Q of the first lens 21 and the second lens 22 are different. The orthographic projection of the vector vertex Q of the first lens 21 onto the substrate 11 coincides with the orthographic projection of the principal optical axis L2 of the first light-emitting unit 121 onto the substrate 11, and the orthographic projection of the vector vertex Q of the second lens 22 onto the substrate 11 is located closer to the center line of the orthographic projection of the principal optical axis of the second light-emitting unit 122 onto the substrate 11. That is, by adjusting the relative positions of the vector vertex Q of the second lens 22 located on both sides of the center line L1, the distribution of the offset angle of the principal optical axis of the light emitted from the second lens 22 located on both sides of the center line L1 is made mirror-symmetric with respect to the center line L1.

[0080] Here, the shapes of the multiple first lenses 21 may be the same or different, the shapes of the multiple second lenses 22 may be the same or different, and the shapes of the first lens 21 and the second lens 22 may be the same or different.

[0081] On the other hand, an embodiment of the present invention also provides a vehicle field of view display device that includes the above-mentioned display module and a windshield for reflecting light from the display module to the eye box, which is the area where the driver's eyes are located.

[0082] The above description has provided a detailed explanation of the display modules and vehicle field-of-view devices provided by the embodiments of this application. However, the above description of embodiments is intended to help understand the core concepts of this application and should not be understood as limiting the scope of protection of this application.

The aforementioned multiple dimming units are: Displaced on the light-emitting surface side of the light-emitting functional layer, it includes a first dimming unit and a second dimming unit, The first dimming unit corresponds to the first light-emitting unit, The second dimming unit corresponds to the second light-emitting unit, In the plane in which the light-emitting functional layer is located, the light-emitting functional layer has a center line perpendicular to the first direction, The main optical axis of the first light-emitting unit overlaps with the main optical axis of the first light-emitting unit after the main optical axis of the dimming unit has passed through the first dimming unit. The dimming main optical axis of the second light-emitting unit, after passing through the second dimming unit, is positioned close to the center line with respect to the main optical axis of the second light-emitting unit. The first dimming unit includes a first lens, The second dimming unit includes a second lens, The structure of the first lens and the structure of the second lens are the same. The plurality of light-emitting units include a first group of light-emitting units and a second group of light-emitting units, The first group of light-emitting units includes a plurality of the first light-emitting units arranged at intervals in the second direction, The second group of light-emitting units includes a plurality of the second light-emitting units arranged at intervals in the second direction, The peripheral display area includes a plurality of second light-emitting units arranged sequentially in the first direction, Both the first and second directions lie on the plane in which the light-emitting functional layer is located, and the second direction is perpendicular to the first direction. In the first direction, if w is the offset interval in which the center of the second lens is shifted toward the center line relative to the principal optical axis of the second light-emitting unit, then in the same group of second light-emitting units, the corresponding principal optical axes of multiple second light-emitting units have the same offset interval w relative to the center of the second lens. The two peripheral display areas are the first display area and the second display area, respectively. The central display area is located between the first display area and the second display area. The second light-emitting unit located in the first display area and the second light-emitting unit located in the second display area are mirror-image symmetric with respect to the center line, The distribution of the offset angle between the dimming principal optical axis emitted from the second lens located on both sides of the center line and the principal optical axis of the second light-emitting unit corresponding to the second lens is arranged in mirror symmetry with respect to the center line. Both the first display area and the second display area include a plurality of sub-display areas arranged at intervals in the first direction, Each of the aforementioned sub-display areas is provided with N of the second light-emitting units. The offset interval w of the multiple second light-emitting units located in the same sub-display area is all equal, and N is a positive integer of 2 or more. In the first direction, the further away from the central display area, the larger the offset interval w of the second light-emitting unit within the sub-display area.
