[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0054] According to the first aspect of this application, Figures 1 to 5 As shown, a display panel 1 is provided, comprising a display area AA and a non-display area NA disposed on one side of the display area AA. The display area AA includes a first region A1 and a second region A2 disposed between the first region A1 and the non-display area NA. The display panel 1 includes a substrate 10, a light-emitting layer 20, an encapsulation layer 30, and a touch layer 40. The light-emitting layer 20 is disposed on one side of the substrate 10 and includes a plurality of light-emitting units 21. The encapsulation layer 30 is disposed on the side of the light-emitting layer 20 facing away from the substrate 10. The thickness of the encapsulation layer 30 located in the first region A1 is greater than the thickness of the encapsulation layer 30 located in the second region A2. The touch layer 40 is disposed on the side of the light-emitting layer 20 away from the substrate 10. The touch layer 40 includes a first metal layer 41 and a second metal layer 42 disposed in different layers. The first metal layer 41 includes a plurality of dimming parts 411, and the second metal layer 42 includes a plurality of touch electrode blocks 421. The touch electrode blocks 421 include touch grids 4211. The dimming parts 411 and the touch grids 4211 are correspondingly disposed between two adjacent light-emitting units 21. The dimming parts 411 are located in the second region A2, and the dimming parts 411 and the touch grids 4211 do not overlap at least partially in the thickness direction of the display panel 1.

[0055] In some embodiments, the display panel 1 may be an OLED panel, a Mini-LED panel, a Micro-LED panel, etc.

[0056] The substrate 10 can be a rigid material or a flexible material. The rigid material can be glass, quartz, or silicon wafer. The flexible material can be one of colorless polyimide (PI), polycarbonate (PC), polynorbornene (PNB), and polyethylene terephthalate (PET).

[0057] like Figure 1 As shown, the display panel 1 has a display area AA and a non-display area NA disposed around the display area AA. The display area AA can be provided with multiple sub-pixels, which can be red sub-pixels, green sub-pixels, and blue sub-pixels, thereby realizing color display. The non-display area NA can be provided with gate driving circuits, etc., which can provide driving signals to the sub-pixels.

[0058] like Figures 2A to 5 As shown, the light-emitting layer 20 includes a plurality of light-emitting units 21, and one light-emitting unit 21 corresponds to one sub-pixel.

[0059] like Figure 2C As shown, when the display panel 1 is an OLED panel, the light-emitting unit 21 includes an anode 201, a light-emitting material layer 202 and a cathode 203 stacked in sequence. Holes are injected into the anode 201 and electrons are injected into the cathode 203. Holes and electrons recombine in the light-emitting material layer 202 to emit light.

[0060] In some embodiments, the anode 201 may be a metal or metal oxide material, such as a stack of one or more of indium tin oxide, indium zinc oxide, silver, etc.

[0061] In some embodiments, the cathode 203 may be made of one or more alloys of silver, aluminum, magnesium, etc.

[0062] The light-emitting unit 21 can emit light in any of the following colors: red, green, and blue. Multiple light-emitting units 21 of different colors can display color images.

[0063] In some embodiments, such as Figure 2C As shown, the encapsulation layer 30 can be a thin-film encapsulation. The encapsulation layer 30 may include a first encapsulation sub-layer 31, a second encapsulation sub-layer 32, and a third encapsulation sub-layer 33 stacked sequentially. The first encapsulation sub-layer 31 and the third encapsulation sub-layer 33 can be inorganic layers, and the second encapsulation sub-layer 32 can be an organic layer. The organic layer can be a single layer or multiple layers formed from any one of polyethylene terephthalate, polyimide, polycarbonate, epoxy resin, polyethylene, and polyacrylate. The inorganic layer can be a single layer or multiple layers of metal oxide or metal nitride, such as silicon nitride, aluminum oxide, or silicon dioxide.

[0064] The inorganic layer can be formed by atomic layer deposition (ALD), plasma-enhanced chemical vapor deposition (PECVD), or the like, but is not limited thereto. The organic layer can be coated by spin coating, slot die coating, or the like, and cured by baking, but is not limited thereto.

[0065] Please refer to Figure 1 and Figure 2C The encapsulation layer 30 covers at least the display area AA of the display panel 1. During the manufacturing of the encapsulation layer 30, the organic layer is made of organic material, and the organic material has fluidity before curing, resulting in different thicknesses of the edge region of the organic layer and the middle region of the organic layer. In the display area AA, the thickness of the organic layer in the second region A2 is less than the thickness of the organic layer in the first region A1.

[0066] As shown in Figures 2A to 2C , the touch layer 40 includes a first metal layer 41 and a second metal layer 42 arranged in different layers. The first metal layer 41 and the second metal layer 42 are located in different film layers in the thickness direction of the display panel 1, and are separated by a first interlayer insulating layer 51. The first metal layer 41 and the second metal layer 42 are formed in one process first and the other process later.

[0067] In some embodiments, the material of the first interlayer insulating layer 51 can be any one of silicon oxide, silicon nitride, silicon oxynitride, or the like.

[0068] In some embodiments, the material of the touch layer 40 can be a conductive material, such as any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or an alloy thereof.

[0069] In some embodiments, the materials of the first metal layer 41 and the second metal layer 42 can be the same or different.

[0070] In some embodiments, please refer to Figure 2A and Figure 2C The touch layer 40 is a mutual capacitance touch. The second metal layer 42 includes a plurality of touch electrode blocks 421, and the touch electrode blocks 421 include driving electrodes and sensing electrodes. The driving electrodes can be arranged in a horizontal direction, and the sensing electrodes can be arranged in a vertical direction. The driving electrodes are used to receive touch driving signals, and the array of sensing electrodes is used to output touch sensing signals. The display panel 1 determines the touch position of a finger on the display panel 1 according to the touch driving signals and the touch sensing signals.

[0071] The first metal layer 41 further comprises a bridge portion (not shown in the figure), one end of the bridge portion is connected with one touch electrode block 421, and the other end of the bridge portion is connected with another adjacent touch electrode block 421; wherein the light adjusting portion 411 is arranged in an insulating manner with the bridge portion.

[0072] The bridge portion is used for connecting two adjacent touch electrode blocks 421, and realizing the signal transmission of the two adjacent touch electrode blocks 421. The bridge portion is arranged in a different layer from the touch electrode block 421, and the bridge portion is connected with the touch electrode block 421 through a via hole.

[0073] The bridge portion is arranged in an insulating manner with the light adjusting portion 411. Since the bridge portion and the light adjusting portion 411 both belong to the first metal layer 41, in order to realize the insulation of the bridge portion and the light adjusting portion 411, the bridge portion and the light adjusting portion 411 can be arranged in a spaced manner. Since the light adjusting portion 411 is located on the first metal layer 41, the light adjusting portion 411 can be manufactured by using the same mask as the bridge portion, without increasing the number of masks and without increasing the process steps.

[0074] As shown in Figure 2A , the touch electrode block 421 comprises a touch mesh 4211. The touch mesh 4211 refers to a metal mesh structure. The metal mesh structure comprises a plurality of intersecting metal wires, and the mesh eyes are formed by the combination of the metal wires, and the light emitting unit 21 is arranged in the mesh eyes. The touch mesh 4211 has small resistance and high sensitivity, which can improve the touch sensitivity of the touch function layer, and the touch electrode block 421 using the touch mesh 4211 has high mechanical strength, which can reduce the weight of the touch layer 40, and when the touch layer 40 is applied to the display panel 1, the display panel 1 can be thinned.

[0075] As shown in Figure 2A , the touch mesh 4211 is arranged between two adjacent light emitting units 21. That is to say, the touch mesh 4211 and the light emitting unit 21 do not overlap in the thickness direction of the display panel 1. Since the touch mesh 4211 will block light, the above arrangement can avoid the touch mesh 4211 from blocking the light emitting unit 21 and affecting the display of the light emitting unit 21.

[0076] As shown in Figure 2C , the touch mesh 4211 is formed on the encapsulation layer 30. Since the thickness of the encapsulation layer 30 in the first area A1 is greater than the thickness of the encapsulation layer 30 in the second area A2, the light blocking degree of the touch layer 40 to the first area A1 and the second area A2 is different.

[0077] As shown in Figure 2A and Figure 2CAs shown, the first metal layer 41 includes a plurality of light adjusting portions 411, which are arranged between two adjacent light emitting units 21. That is, the light adjusting portions 411 do not overlap with the light emitting units 21 in the thickness direction of the display panel 1, so as to avoid the light adjusting portions 411 from blocking the light emitting units 21 and affecting the display of the light emitting units 21.

[0078] Please refer to Figure 1 , Figure 2A and Figure 2C , the light adjusting portions 411 are located in the second area A2. That is, the light adjusting portions 411 are not arranged in the first area A1, but only in the second area A2. Since the light adjusting portions 411 do not at least partially overlap with the touch control grids 4211 in the thickness direction of the display panel 1, the light adjusting portions 411 can block part of the light of the light emitting units 21 in the second area A2, so as to reduce the difference between the light emitted by the light emitting units 21 in the first area A1 and the second area A2, and improve the color difference of the second area A2. The width of the light adjusting portions 411 can be set as needed, and the light adjusting portions 411 will not affect the touch function of the display panel 1.

[0079] In some embodiments, as shown in Figure 2C , a driving circuit layer is further arranged between the substrate 10 and the light emitting layer 20. The driving circuit layer includes a thin film transistor 60. The thin film transistor 60 includes a source 61, a drain 62, a gate 63 and an active portion 64. The drain 62 can be electrically connected with the anode 201, so as to provide a driving voltage for the anode 201.

[0080] In some embodiments, as shown in Figure 2C , the display panel 1 further includes a cover plate 70, which is arranged on the side of the touch control layer 40 away from the substrate 10. The cover plate 70 is made of a flexible material such as polyimide, so that the display panel 1 has good bending performance. The cover plate 70 can also be made of glass, but is not limited thereto.

[0081] Optionally, as shown in Figures 2A to 5 , the plurality of light adjusting portions 411 include a first light adjusting sub-portion 4111 close to the first area A1 and a second light adjusting sub-portion 4112 away from the first area A1; wherein the spacing s1 between the orthographic projection pattern of the first light adjusting sub-portion 4111 on the substrate 10 and the orthographic projection pattern of the adjacent light emitting unit 21 on the substrate 10 is different from the spacing s2 between the orthographic projection pattern of the second light adjusting sub-portion 4112 on the substrate 10 and the orthographic projection pattern of the adjacent light emitting unit 21 with the same color on the substrate 10.

[0082] As shown in Figure 2A , Figures 3 to 5As shown, the light adjusting portion 411 includes a first light adjusting sub-portion 4111 and a second light adjusting sub-portion 4112. The first light adjusting sub-portion 4111 and the second light adjusting sub-portion 4112 differ in position relative to the first area A1. The first light adjusting sub-portion 4111 is closer to the first area A1, and the second light adjusting sub-portion 4112 is farther from the first area A1 relative to the first light adjusting sub-portion 4111. In other words, the second light adjusting sub-portion 4112 is located on a side of the first light adjusting sub-portion 4111 that is farther from the first area A1.

[0083] In some embodiments, the first light adjusting sub-portion 4111 and the second light adjusting sub-portion 4112 can be located on the same side of the first area A1. As shown in FIG. 4A, the first light adjusting sub-portion 4111 and the second light adjusting sub-portion 4112 are located on the same side of the first area A1. Figure 1 As shown, the first area A1 is located in the middle of the display area AA, and the second area A2 is located on the periphery of the first area A1.

[0084] In some embodiments, as shown in FIG. 4B, the second area A2 can be located on the left side of the first area A1. Figure 1 Figure 2A As shown, the second area A2 can be located on the left side of the first area A1.

[0085] In some embodiments, as shown in FIG. 4C, the second area A2 can be located on the upper side of the first area A1. Figure 1 Figure 3 As shown, the second area A2 can be located on the upper side of the first area A1. It should be noted that the second area A2 can also include an O-CUT area, which is a circular area in Figure 1 . The O-CUT area can be used to set up camera components and the like.

[0086] In some embodiments, as shown in FIG. 4D, the second area A2 can be located on the right side of the first area A1. Figure 1 Figure 4 As shown, the second area A2 can be located on the right side of the first area A1.

[0087] In some embodiments, as shown in FIG. 4E, the second area A2 can be located on the lower side of the first area A1. Figure 1 Figure 5 As shown, the second area A2 can be located on the lower side of the first area A1.

[0088] In some embodiments, the first light adjusting sub-portion 4111 and the second light adjusting sub-portion 4112 can be located on the same side of the first area A1.

[0089] As shown in FIG. 4A, the first light adjusting sub-portion 4111 and the second light adjusting sub-portion 4112 are located on the same side of the first area A1. Figure 2A Figures 3 to 5 As shown, the first light adjusting sub-portion 4111 and the second light adjusting sub-portion 4112 are located on the same side of the first area A1.

[0090] ​​​​​Note that s1 and s2 correspond to the same light emitting color of the light emitting unit 21. For example, when s1 corresponds to the pitch of the light emitting unit 21 of which the light emitting color is red and the adjacent first light adjusting sub-section 4111, s2 corresponds to the pitch of the light emitting unit 21 of which the light emitting color is red and the adjacent second light adjusting sub-section 4112.

[0091] When s1 corresponds to the pitch of the light emitting unit 21 of which the light emitting color is green and the adjacent first light adjusting sub-section 4111, s2 corresponds to the pitch of the light emitting unit 21 of which the light emitting color is green and the adjacent second light adjusting sub-section 4112.

[0092] When s1 corresponds to the pitch of the light emitting unit 21 of which the light emitting color is blue and the adjacent first light adjusting sub-section 4111, s2 corresponds to the pitch of the light emitting unit 21 of which the light emitting color is blue and the adjacent second light adjusting sub-section 4112.

[0093] In some embodiments, as shown in FIG. 12A, the boundary line in the orthographic projection pattern of the first light adjusting sub-section 4111 close to the light emitting unit 21 extends in the same direction as the boundary line in the orthographic projection pattern of the light emitting unit 21 close to the first light adjusting sub-section 4111. For example, the boundary line can be a straight line. Figure 2A , Figures 3 to 5 In some embodiments, as shown in FIG. 12A, the boundary line in the orthographic projection pattern of the first light adjusting sub-section 4111 close to the light emitting unit 21 extends in the same direction as the boundary line in the orthographic projection pattern of the light emitting unit 21 close to the first light adjusting sub-section 4111. For example, the boundary line can be a straight line.

[0094] In some embodiments, as shown in FIG. 12A, the boundary line in the orthographic projection pattern of the first light adjusting sub-section 4111 close to the light emitting unit 21 extends in the same direction as the boundary line in the orthographic projection pattern of the light emitting unit 21 close to the first light adjusting sub-section 4111. For example, the boundary line can be a straight line.

[0095] In some embodiments, the pitch s1 of the orthographic projection pattern of the first light adjusting sub-section 4111 on the substrate 10 and the orthographic projection pattern of the adjacent light emitting unit 21 on the substrate 10 is different from the pitch s2 of the orthographic projection pattern of the second light adjusting sub-section 4112 on the substrate 10 and the orthographic projection pattern of the adjacent light emitting unit 21 of which the light emitting color is the same on the substrate 10.

[0096] In some embodiments, the pitch s1 of the orthographic projection pattern of the first light adjusting sub-section 4111 on the substrate 10 and the orthographic projection pattern of the adjacent light emitting unit 21 on the substrate 10 is different from the pitch s2 of the orthographic projection pattern of the second light adjusting sub-section 4112 on the substrate 10 and the orthographic projection pattern of the adjacent light emitting unit 21 of which the light emitting color is the same on the substrate 10.

[0097] In other embodiments, the pitch s1 of the orthographic projection pattern of the first light adjusting sub-section 4111 on the substrate 10 and the orthographic projection pattern of the adjacent light emitting unit 21 on the substrate 10 is smaller than the pitch s2 of the orthographic projection pattern of the second light adjusting sub-section 4112 on the substrate 10 and the orthographic projection pattern of the adjacent light emitting unit 21 on the substrate 10.

[0098] Optionally, as shown in Figure 2A , Figure 2B , Figures 3 to 5 , the plurality of light emitting units 21 includes first color units 211, and the pitch s11 of the orthographic projection pattern of the first light adjusting sub-section 4111 on the substrate 10 and the orthographic projection pattern of the adjacent first color unit 211 on the substrate 10 is greater than the pitch s21 of the orthographic projection pattern of the second light adjusting sub-section 4112 on the substrate 10 and the orthographic projection pattern of the adjacent first color unit 211 on the substrate 10.

[0099] In some embodiments, the light emitting color of the first color unit 211 can be green, but is not limited thereto.

[0100] As shown in Figure 2B , an enlarged structural schematic view at E in Figure 2A is shown. The pitch s11 of the orthographic projection pattern of the first light adjusting sub-section 4111 on the substrate 10 and the orthographic projection pattern of the adjacent first color unit 211 on the substrate 10 refers to the distance between the boundary line of the first light adjusting sub-section 4111 close to the first color unit 211 and the first color unit 211 close to the first light adjusting sub-section 4111 in Figure 2B .

[0101] The pitch s21 of the orthographic projection pattern of the second light adjusting sub-section 4112 on the substrate 10 and the orthographic projection pattern of the adjacent first color unit 211 on the substrate 10 refers to the distance between the boundary line of the second light adjusting sub-section 4112 close to the first color unit 211 and the first color unit 211 close to the second light adjusting sub-section 4112 in Figure 2B .

[0102] It should be noted that the first light adjusting sub-section 4111 and the second light adjusting sub-section 4112 are relative.

[0103] Specifically, as shown in Figure 2A , the pitch s11 of the orthographic projection pattern of the first light adjusting sub-section 4111 on the substrate 10 and the orthographic projection pattern of the adjacent first color unit 211 on the substrate 10 is greater than the pitch s21 of the orthographic projection pattern of the second light adjusting sub-section 4112 on the substrate 10 and the orthographic projection pattern of the adjacent first color unit 211 on the substrate 10. That is, in Figure 2AIn the middle, the distance between the first color unit 211 on the right and the first dimming sub-unit 4111 is greater than the distance between the first color unit 211 on the left and the corresponding second dimming sub-unit 4112.

[0104] like Figure 3 As shown, the distance s11 between the orthographic projection pattern of the first dimming unit 4111 on the substrate 10 and the orthographic projection pattern of the adjacent first color unit 211 on the substrate 10 is greater than the distance s21 between the orthographic projection pattern of the second dimming unit 4112 on the substrate 10 and the orthographic projection pattern of the adjacent first color unit 211 on the substrate 10. This means that in Figure 3 In the middle, the distance between the lower first color unit 211 and the first dimming sub-unit 4111 is greater than the distance between the upper first color unit 211 and the corresponding second dimming sub-unit 4112.

[0105] like Figure 4 As shown, the distance s11 between the orthographic projection pattern of the first dimming unit 4111 on the substrate 10 and the orthographic projection pattern of the adjacent first color unit 211 on the substrate 10 is greater than the distance s21 between the orthographic projection pattern of the second dimming unit 4112 on the substrate 10 and the orthographic projection pattern of the adjacent first color unit 211 on the substrate 10. This means that in Figure 4 In the middle, the distance between the first color unit 211 on the left and the first dimming sub-unit 4111 is greater than the distance between the first color unit 211 on the right and the corresponding second dimming sub-unit 4112.

[0106] like Figure 5 As shown, the distance s11 between the orthographic projection pattern of the first dimming unit 4111 on the substrate 10 and the orthographic projection pattern of the adjacent first color unit 211 on the substrate 10 is greater than the distance s21 between the orthographic projection pattern of the second dimming unit 4112 on the substrate 10 and the orthographic projection pattern of the adjacent first color unit 211 on the substrate 10. This means that in Figure 5 In the middle, the distance between the upper first color unit 211 and the first dimming sub-unit 4111 is greater than the distance between the lower first color unit 211 and the corresponding second dimming sub-unit 4112.

[0107] Optionally, such as Figure 2A , Figure 3 As shown, along the direction from the second region A2 to the first region A1, the spacing between the orthographic projection pattern of the dimming unit 411 on the substrate 10 and the orthographic projection pattern of the first color unit 211 on the substrate 10 increases.

[0108] In some embodiments, Figure 4 In the middle, along the left-to-right direction, the spacing between the orthographic projection pattern of the dimming unit 411 on the substrate 10 and the orthographic projection pattern of the first color unit 211 on the substrate 10 increases.

[0109] In some embodiments, in the direction from up to down, the interval between the orthographic projection pattern of the light adjusting portion 411 on the substrate 10 and the orthographic projection pattern of the first color unit 211 on the substrate 10 is increased. Figure 5

[0110] In some embodiments, in the direction from right to left, the interval between the orthographic projection pattern of the light adjusting portion 411 on the substrate 10 and the orthographic projection pattern of the first color unit 211 on the substrate 10 is increased. Figure 2A

[0111] In some embodiments, in the direction from down to up, the interval between the orthographic projection pattern of the light adjusting portion 411 on the substrate 10 and the orthographic projection pattern of the first color unit 211 on the substrate 10 is increased. Figures 3 to 5

[0112] It should be understood that in other embodiments, the interval between the orthographic projection pattern of the light adjusting portion 411 on the substrate 10 and the orthographic projection pattern of the first color unit 211 on the substrate 10 can also be distributed in other regularities, which can be adaptively adjusted according to the color difference of the second area A2.

[0113] Optionally, the light emitting unit 21 comprises a second color unit 212, and the interval s12 between the orthographic projection pattern of the first light adjusting sub-portion 4111 on the substrate 10 and the orthographic projection pattern of the adjacent second color unit 212 on the substrate 10 is less than the interval s22 between the orthographic projection pattern of the second light adjusting sub-portion 4112 on the substrate 10 and the orthographic projection pattern of the adjacent second color unit 212 on the substrate 10.

[0114] In some embodiments, the light emitting color of the second color unit 212 can be red, but is not limited thereto.

[0115] As shown in FIG. 13, Figure 2B Figure 2A FIG. 13 shows an enlarged structure diagram at E in FIG. 12. The interval s12 between the orthographic projection pattern of the first light adjusting sub-portion 4111 on the substrate 10 and the orthographic projection pattern of the adjacent second color unit 212 on the substrate 10 refers to, in Figures 3 to 5 FIG. 13, the interval between the boundary line of the first light adjusting sub-portion 4111 close to the second color unit 212 and the second color unit 212 close to the first light adjusting sub-portion 4111.

[0116] The interval s22 between the orthographic projection pattern of the second light adjusting sub-portion 4112 on the substrate 10 and the orthographic projection pattern of the adjacent second color unit 212 on the substrate 10 refers to, in Figure 6 ​​​​In the middle, the distance between the boundary line of the second dimming sub-section 4112 near the second color unit 212 and the distance between the second color unit 212 near the second dimming sub-section 4112.

[0117] It should be noted that the first photonic unit 4111 and the second photonic unit 4112 are relative terms.

[0118] Specifically, such as Figure 6 As shown, the distance s12 between the orthographic projection pattern of the first dimming unit 4111 on the substrate 10 and the orthographic projection pattern of the adjacent second color unit 212 on the substrate 10 is smaller than the distance s22 between the orthographic projection pattern of the second dimming unit 4112 on the substrate 10 and the orthographic projection pattern of the adjacent second color unit 212 on the substrate 10. This means that in Figure 2A In the middle, the distance between the second color unit 212 on the right and the first dimming sub-unit 4111 is smaller than the distance between the second color unit 212 on the left and the corresponding second dimming sub-unit 4112.

[0119] like Figure 6 As shown, the distance s12 between the orthographic projection pattern of the first dimming unit 4111 on the substrate 10 and the orthographic projection pattern of the adjacent second color unit 212 on the substrate 10 is smaller than the distance s22 between the orthographic projection pattern of the second dimming unit 4112 on the substrate 10 and the orthographic projection pattern of the adjacent second color unit 212 on the substrate 10. This means that in Figure 6 In the middle, the distance between the lower second color unit 212 and the first dimming sub-unit 4111 is smaller than the distance between the upper second color unit 212 and the corresponding second dimming sub-unit 4112.

[0120] like Figure 1 As shown, the distance s12 between the orthographic projection pattern of the first dimming unit 4111 on the substrate 10 and the orthographic projection pattern of the adjacent second color unit 212 on the substrate 10 is smaller than the distance s22 between the orthographic projection pattern of the second dimming unit 4112 on the substrate 10 and the orthographic projection pattern of the adjacent second color unit 212 on the substrate 10. This means that in Figure 6 In the middle, the distance between the second color unit 212 on the left and the first dimming sub-unit 4111 is smaller than the distance between the second color unit 212 on the right and the corresponding second dimming sub-unit 4112.

[0121] like Figure 1 As shown, the distance s12 between the orthographic projection pattern of the first dimming unit 4111 on the substrate 10 and the orthographic projection pattern of the adjacent second color unit 212 on the substrate 10 is smaller than the distance s22 between the orthographic projection pattern of the second dimming unit 4112 on the substrate 10 and the orthographic projection pattern of the adjacent second color unit 212 on the substrate 10. This means that in Figure 6In some embodiments, as shown in FIG. 2, the distance between the orthographic projection pattern of the light-emitting unit 21 on the substrate 10 and the orthographic projection pattern of the light-adjusting unit 411 on the substrate 10 is gradually reduced along the direction from the first region Al to the second region A2.

[0122] Optionally, along the direction from the second region A2 to the first region Al, the distance between the orthographic projection pattern of the light-adjusting unit 411 on the substrate 10 and the orthographic projection pattern of the second color unit 212 on the substrate 10 is gradually reduced.

[0124] In some embodiments, as shown in FIG. 2, the distance between the orthographic projection pattern of the light-emitting unit 21 on the substrate 10 and the orthographic projection pattern of the light-adjusting unit 411 on the substrate 10 is gradually reduced along the direction from the first region Al to the second region A2. Figure 6 In some embodiments, as shown in FIG. 2, the distance between the orthographic projection pattern of the light-emitting unit 21 on the substrate 10 and the orthographic projection pattern of the light-adjusting unit 411 on the substrate 10 is gradually reduced along the direction from the first region Al to the second region A2.

Figures 2A to 5 In some embodiments, as shown in FIG. 2, the distance between the orthographic projection pattern of the light-emitting unit 21 on the substrate 10 and the orthographic projection pattern of the light-adjusting unit 411 on the substrate 10 is gradually reduced along the direction from the first region Al to the second region A2.

[0128] Optionally, as shown in FIG. 2, the light-adjusting unit 411 is arranged around the light-emitting unit 21. That is, the orthographic projection pattern of the light-adjusting unit 411 on the substrate 10 can be a closed pattern, so that the light-adjusting unit 411 can block the light-emitting unit 21 in all directions, further improving the color difference of the second region A2. Figure 7 、 ​ In some embodiments, as shown in FIG. 2, the distance between the orthographic projection pattern of the light-emitting unit 21 on the substrate 10 and the orthographic projection pattern of the light-adjusting unit 411 on the substrate 10 is gradually reduced along the direction from the first region Al to the second region A2.
