[0001] The present application relates to the field of display technology, and in particular to a display module and a vehicle vision display device. [Background technology]

[0002] A head-up display (HUD) is a flying aid originally used in aircraft. At present, HUDs are widely used in automobiles, and the principle is that the image on the display is reflected by one or two mirrors and projected onto the windshield of the car, forming a high-brightness virtual image in front of the driver's eyes.

[0003] Due to the influence of the distance between the human eye 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 displayed image seen by the human eye. That is, the brightness of the central area of ​​the displayed image seen by the human eye is bright, and the brightness of the peripheral area of ​​the displayed image seen by the human eye gradually becomes darker. Therefore, how to improve the brightness uniformity of the displayed image seen by the human eye is an urgent issue that needs to be solved.

Overall luminance is also improved, with the display luminance of the peripheral display area within the narrow viewing angle range being 90% or more of the display luminance of the central display area.

[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 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. The light-emitting units 12 are sequentially arranged in the first direction X in the peripheral display area A2, the central display area A1, and the peripheral display area A2. The 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 light-adjusting 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 a 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 dimming main optical axis of the first light-emitting unit 121 after passing through the first dimming unit 21 overlaps with the main optical axis of the first light-emitting unit 121. The dimming main optical axis of the second light-emitting unit 122 after passing through the second dimming unit 22 is disposed close to the center line of 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 main optical axis of the first light-emitting unit 121 after passing through the first dimming unit 21. The dimming main optical axis of the second light-emitting unit 122 after passing through the second dimming unit 22 is positioned close to the center line of the main optical axis of the second light-emitting unit 122. As a result, in the narrow viewing angle range, the luminance at a viewing angle of 10° is approximately 65% ​​of the luminance at a viewing angle of 0° compared to a light-emitting functional layer without a dimming unit. The luminance uniformity of the light-emitting functional layer is significantly improved by the light-emitting functional layer with a dimming unit. Overall luminance is also improved, with the display luminance of the peripheral display area within the narrow viewing angle range being 90% or more of the display luminance of the central display area.

[0032] In an embodiment 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 displays meter information (such as speed) and navigation information in front of the driver's field of vision, allowing the driver to see the meter information and navigation information in front of their field of vision without having to look down at the dashboard or center display under the steering wheel, thereby improving braking reaction time in an emergency and improving driving safety.

[0033] In an embodiment 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. The first lens 21 and the second lens 22 have the same structure and may be a conventional convex lens. The plurality of light-emitting units 12 include a first light-emitting unit group and a second light-emitting unit group. The first light-emitting unit group includes a plurality of first light-emitting units 121 arranged at intervals in the second direction Y. The second light-emitting unit group 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 light-emitting unit groups 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 length direction of the light-emitting functional layer.

[0034] Here, if the offset distance in the first direction X by which the center of the second lens 22 is shifted in a direction approaching the center line L1 relative to the main optical axis of the second light-emitting unit 122 is w, then in the same second light-emitting unit group, the corresponding main optical axes of multiple second light-emitting units 122 have the same offset distance w relative to the center of the second lens 22.

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

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

[0037] In an embodiment of the present invention, the central display area A1 includes at least one first light-emitting unit group. Specifically, when the resolution of the light-emitting functional layer 10 is W*H, 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, when H is an odd number, the central display area A1 includes an odd number of first light-emitting unit groups, such as one first light-emitting unit group, three first light-emitting unit groups, five first light-emitting unit groups, seven first light-emitting unit groups, or nine first light-emitting unit groups, etc. Preferably, the central display area A1 includes one first light-emitting unit group. When H is an even number, the central display region 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, etc., and preferably, the central display region A1 includes two first light-emitting unit groups.

[0038] In this embodiment of the present invention, the two peripheral display areas A2 include a first display area and a second display area, and the central display area A1 is located between the first display area and the second display area. The plurality of second light-emitting units 121 located in the first display area and the plurality of second light-emitting units located in the second display area are mirror-symmetrical with respect to the center line L1. The distribution of offset angles between the dimming main optical axes emitted from the second lenses 22 located on both sides of the center line L1 and the main optical axes of the second light-emitting units 122 corresponding to the second lenses is mirror-symmetrical with respect to the center line L1.

[0039] In an embodiment of the present invention, the peripheral display area A2 includes a plurality of second light-emitting unit groups spaced apart in the first direction X. Here, the offset intervals w of the second light-emitting units 121 located in the same second light-emitting unit group are equal.

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

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

[0042] In the present embodiment, the offset distance that approaches the center line in the first direction between the center of the orthogonal projection onto the substrate of the second light-emitting unit of the kth second light-emitting unit group arranged away from the central display area A1 and the center of the orthogonal projection onto the substrate of the second lens is calculated using the following formula. w=a / (m / 2)*(k-1)

[0043] Here, the target distance at which the orthogonal projection on the substrate 11 of the main optical axis of the second light-emitting unit 122 after the main optical axis of the second light-emitting unit 122 in the second light-emitting unit group farthest from the central display area A1 passes through the second dimming unit 22 approaches the center line in the first direction X is defined as 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 defined as m, and the kth second light-emitting unit group arranged in the direction away from the central display area A1 is defined as k.

[0044] For example, if the width of the light-emitting functional layer 10 is 200 μm, the total number m of the light-emitting units 12 arranged at intervals in the first direction X on the light-emitting functional layer 10 is 650 (the sum of the first light-emitting unit group and the second light-emitting unit group), and the simulation results show that the target spacing a of the second light-emitting units 121 of the second light-emitting unit group that is farthest from the central display region A1 is 5 μm, then the offset spacing w of the second light-emitting units 121 of the second (k is 2) second light-emitting unit group arranged in the direction away from the central display region A1 is w=5 / (650 / 2)*1=15.4 nm. Here, the resolution and size of the light-emitting functional layer 10 differ, and the corresponding value of the offset spacing w differs. Generally, the value of a / (m / 2) is between 2 nm and 1000 nm, for example, the values ​​of a / (m / 2) include 2 nm, 3 nm, 5 nm, 10 nm, 15 nm, 20 nm, 25 nm, 30 nm... 100 nm, 200 nm,... 500 nm, 600 nm... 800 nm, 900 nm, 1000 nm, etc.

[0045] In an embodiment of the present invention, the shape of the lens 20 includes at least one of a cylinder, a circular table, a cone, and a trapezoid.

[0046] In the embodiment of the present application, the display module further includes an optical imaging unit for transmitting the light emitted through the light-emitting functional layer 10 to the windshield, and the extension of the light in the reverse direction after being reflected by the windshield forms a virtual image at a first predetermined position. The larger the angle between the eyebox and the peripheral field angle of the virtual image, the larger the offset distance w of the second light-emitting unit 121 away from the central display area A1, and the eyebox is the area where the driver's eyes are located.

[0047] As shown in Figure 2a, in a conventional display module, the light emitted through the first lens 21 and the light emitted through the second lens 22 are parallel rays, and 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 becomes darker.

[0048] As shown in Figure 2b, in the display module provided in this 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 (emitted toward the central axis direction 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 are consistent.

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

[0050] As shown in FIG. 3b, after the second light-emitting unit 121 in the light-emitting unit 12 located in the peripheral display area A2 is shifted in a direction away from the central display area A1, the display luminance of the central display area A1 becomes 120 candela / m 2 ~140 candela / m 2 In this case, the display luminance of the peripheral display area A2 (corresponding to the display luminance at a horizontal viewing angle of ±10° in the example) is 120 candela / m 2 ~140 candela / m 2 In other words, the difference between the display luminance of the central display area A1 and the display luminance of the peripheral display area A2 becomes smaller, and the luminance of the peripheral display area and the luminance of the central area of ​​the display image that are visible to the human eye match (the display luminance of the peripheral display area A2 is 90% or more of the display luminance of the central display area A1), thereby improving the uniformity of the luminance of the display image that is visible to the human eye.

[0051] As shown in FIG. 4 , an embodiment of the present application provides a display module 200. The display module 200 differs from the display module 100 in that the peripheral display region A2 of the display module 200 includes a first display region and a second display region spaced apart in the first direction X, and the central display region A1 is located between the first display region and the second display region. Both the first display region and the second display region include a plurality of sub-display regions A21 spaced apart in the first direction X. Each of the sub-display regions A21 has N second light-emitting unit groups. That is, the number of second light-emitting unit groups in each of the sub-display regions A21 is equal. Here, the offset intervals w between the second light-emitting units 121 located in the same sub-display region A21 are equal. N is a positive integer equal to or greater than 2, for example, N is 3, 4, 5, 6, 7, 8, 9, 10...15...20...25...30...50...100...

[0052] In the first direction, the second light-emitting units 121 in the sub-display area farther from the central display area have larger offset intervals w.

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

[0054] For example, the sub-display region A21 is adjacent to the central display region A1. That is, in the first direction X, the first sub-display region A21 includes five second light-emitting unit groups. Of the five second light-emitting unit groups in the sub-display region A21, the offset interval w between the second light-emitting units 121 is equal to the offset interval w between the second light-emitting units 121 in the third second light-emitting unit group in the sub-display region A21, which is arranged in a direction away from the central display region A1.

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

[0056] In an embodiment 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 second light-emitting unit groups in the sub-display area A21.

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

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

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

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

[0061] The display module 200 provided by the present invention offsets multiple second light-emitting units 121 in N second light-emitting unit groups at the same pitch, thereby reducing the process accuracy by N times and increasing the offset step size, thereby avoiding the phenomenon where the offset interval w is too small to achieve the process accuracy when offsetting multiple second light-emitting units 121 in a single second light-emitting unit group, and can improve the brightness uniformity of the display module while reducing the difficulty of the process.

[0062] 5 and 6, an embodiment of the present invention provides a display module 300. The display module 300 differs from the display module 200 in that the number of second light-emitting unit groups increases in the sub-display regions A21 that are farther from the central display region A1. That is, the numbers of second light-emitting unit groups in the multiple sub-display regions A21 along the direction away from the central display region A1 are not all equal.

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

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

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

[0066] In the example shown in Figure 6, the number of second light-emitting unit groups in multiple sub-display areas A21 arranged in a direction away from the central display area A1 may increase by one in sequence, for example, the numbers of second light-emitting unit groups in three sub-display areas A21 arranged in a direction away from the central display area A1 are shown to be 2, 3, and 4, respectively.

[0067] Furthermore, the number of second light-emitting unit groups added to the multiple sub-display areas A21 arranged in a direction away from the central display area A1 is not equal; for example, if the number of added second light-emitting unit groups is a multiple of 2, the numbers of second light-emitting unit groups arranged in the three sub-display areas A21 arranged in a direction away from the central display area A1 will be 2, 4, and 8, respectively.

[0068] As shown in FIGS. 7-10 , an embodiment of the present application provides a display module 400. The display module 400 differs from the display module 100 in that, in the display module 400, a first light-emitting unit group corresponds to n1 first lenses 21, and a second light-emitting unit group corresponds to n2 second lenses 22, where n1 and n2 may or may not be equal to each other, and n1 and n2 are both positive integers greater than or equal to 2, 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 light emitting unit group and the second light emitting unit group are arranged along the first direction X.

[0069] In the example shown in FIG. 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 FIG. 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 an embodiment of the present invention, the orthogonal projection of the first lens 21 onto the substrate 11 covers the orthogonal projection of the m1 first light-emitting units 121 of the first light-emitting unit group onto the substrate 11, and the orthogonal projection of the second lens 22 onto the substrate 11 covers the orthogonal projection of the main optical axes of the 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 equal to or greater than 2. For example, m1 may be equal to 3, 4, 5, 6, 7, 8, 9, 10... and m2 may be equal to 3, 4, 5, 6, 7, 8, 9, 10...

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

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

[0075] 9, an embodiment of the present invention provides a display module 500. The display module 500 differs from the display module 100 in that the first lens 21 of the display module 500 includes a first sub-lens 211 and a second sub-lens 212, the orthogonal projection of the first sub-lens 211 onto the substrate 11 covers the orthogonal projection of at least two first light-emitting units 121 in the first light-emitting unit group onto the substrate 11, and the orthogonal projection of the second sub-lens 212 onto the substrate 11 covers the orthogonal 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, and the orthogonal projection of the third sub-lens 221 onto the substrate 11 covers the orthogonal projection of at least two second light-emitting units 121 of the second light-emitting unit group onto the substrate 11, and the orthogonal projection of the fourth sub-lens 222 onto the substrate 11 covers the orthogonal projection of the main optical axis of one second light-emitting unit 121 of the second light-emitting unit group onto the substrate.

[0076] 9, the orthogonal projection of the first sub-lens 211 onto the substrate 11 covers the orthogonal projection of the two first light-emitting units 121 of the first light-emitting unit group onto the substrate 11, and the orthogonal projection of the second sub-lens 212 onto the substrate 11 covers the orthogonal projection of the one first light-emitting unit 121 of the first light-emitting unit group onto the substrate 11. The orthogonal projection of the third sub-lens 221 onto the substrate 11 covers the orthogonal projection of the main optical axes of the two second light-emitting units 121 in the second light-emitting unit group onto the substrate 11, and the orthogonal projection of the fourth sub-lens 222 onto the substrate 11 covers the orthogonal projection of the main optical axis of the one second light-emitting unit 121 in the second light-emitting unit group onto the substrate 11.

[0077] 10 , an embodiment of the present invention provides a display module 600. The display module 600 differs from the display module 100 in that the first light-emitting units 121 of the first light-emitting unit group of the display module 600 correspond to one first lens 21, and the second light-emitting units 122 of the second light-emitting unit group correspond to one second lens 22. Specifically, the orthogonal projection of the first lens 21 onto the substrate 11 covers the orthogonal projection of the first light-emitting units 121 of the first light-emitting unit group onto the substrate 11, and the orthogonal projection of the second lens 22 onto the substrate 11 covers the orthogonal projection of the main optical axes of the 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 lenses 21 and the second lenses 22 may be the same or different.

[0079] 11 , an embodiment of the present invention provides a display module 700. The display module 700 differs from the display module 100 in that the first lenses 21 of the display module 700 are arranged in one-to-one correspondence with the first light-emitting units 121, and the second lenses 22 are arranged in one-to-one correspondence with the second light-emitting units 122. The positions of the vector vertices Q of the first lenses 21 and the second lenses 22 are different. The orthogonal projection of the vector vertex Q of the first lens 21 onto the substrate 11 overlaps with the orthogonal projection of the main optical axis L2 of the first light-emitting unit 121 onto the substrate 11, and the orthogonal projection of the vector vertex Q of the second lens 22 onto the substrate 11 is located closer to the center line of the orthogonal projection of the main optical axis L2 of the second light-emitting unit 122 onto the substrate 11. That is, by adjusting the relative positions of the vector vertices Q of the second lenses 22 located on both sides of the center line L1, the offset angle distribution of the main optical axes of the light emitted from the second lenses 22 located on both sides of the center line L1 is mirror-symmetrical 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 lenses 21 and the second lenses 22 may be the same or different.
