Thus, while a user is viewing the images displayed on multiple displays in the display module, the light guided to the seam by the dimming structure can also reach the user's eyes. This increases the amount of light at the seam location, thereby mitigating the visual disruption caused by the seam and improving the user's viewing experience. Attached Figure Description

Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Figure 3 This is a cross-sectional view of a display module provided in an embodiment of this application; Figure 4 This is a cross-sectional view of another display module provided in an embodiment of this application; Figure 5 This is a cross-sectional view of another display module provided in the embodiments of this application; Figure 6 This is a cross-sectional view of another display module provided in the embodiments of this application; Figure 7This is a cross-sectional view of another display module provided in the embodiments of this application; Figure 8 This is a cross-sectional view of a display module provided in another embodiment of this application. Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0019] This application provides a display module; please refer to... Figure 1 , Figure 1 This is a top view of a display module provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shows a cross-sectional view of the display module at point A-A'. The display module may include: multiple displays 100 arranged in a tiled configuration, and a dimming structure 200.
[0020] There is a splicing gap V between any two adjacent displays 100 in the display module. Here, the display 100 may have a display area M and a non-display area N. The display area M of the display 100 is used to display the image, and the non-display area N is not used to display the image. The non-display area N of the display 100 is distributed around the display area M.
[0021] Thus, in two spliced displays 100, adjacent non-display areas N of the two displays 100 will form a splicing gap V. No image is displayed at the splicing gap V, causing a visual break when the user views the image displayed by the display module, thus affecting the user's viewing experience.
[0022] In this application, the display area M of the display screen 100 in the display module may have multiple sub-pixels 101 distributed within it. Among the multiple sub-pixels 101 in the display area M of the display screen 100, the sub-pixel 101 located near the splicing gap V can be a target sub-pixel 101a.
[0023] The dimming structure 200 in the display module can be located on the light-emitting side of the sub-pixel 101a, and can be positioned at least near the splicing seam V. The dimming structure 200 in the display module can be used to guide at least a portion of the light emitted by the target sub-pixel 101a to the location of the splicing seam V.
[0024] In this way, while the user is viewing the images displayed on the multiple displays 100 in the display module, the light guided by the dimming structure 200 to the location of the splicing gap V can also enter the user's eyes. This increases the amount of light at the location of the splicing gap V, thereby improving the visual discontinuity caused by the splicing gap V and enhancing the user's viewing experience.
[0025] In summary, this application provides a display module including multiple displays and multiple dimming structures. A seam is formed between any two adjacent displays, and the sub-pixel closest to the seam among the multiple sub-pixels within the display area of each display is the target sub-pixel. The dimming structure, located on the light-emitting side of the sub-pixel and positioned at the seam, can guide at least the light emitted by the target sub-pixel to the seam. Thus, while a user is viewing the images displayed on the multiple displays in the display module, the light guided by the dimming structure to the location of the seam can also enter the user's eye. This increases the amount of light at the seam location, thereby mitigating the visual disruption caused by the seam and improving the user's viewing experience.
[0026] In this application, the dimming structure 200 in the display module can be implemented in the following two optional ways: In the first optional implementation, such as Figure 3 As shown, Figure 3 This is a cross-sectional view of a display module provided in an embodiment of this application. The orthographic projection of the dimming structure 200 in the display module onto the display surface P of the display module may not overlap with the orthographic projection of the splicing gap V onto the display surface P of the display module. Dimming structures 200 may be distributed on both sides of the splicing gap V in the target direction X. Here, the target direction X may be parallel to the display surface P of the display module and may be perpendicular to the extension direction of the splicing gap V.
[0027] It should be noted that the display surface P of the display module can be located on the light-emitting side of multiple sub-pixels 101 within the display area M of the display screen 100. Furthermore, the display surface P of the display module can be one side of the back ion pixel 101, which is a layer of the back ion pixel 101 in the display screen 100.
[0028] Optional, such as Figure 2 As shown, for the dimming structure 200 and the display screen 100 distributed on the same side of the splicing gap V, in the target direction X, the dimming structure 200 can be located on the side of the target sub-pixel 101a in the display screen 100 that faces away from the splicing gap V. Furthermore, the side of the dimming structure 200 facing the splicing gap V in the target direction X can be a reflective surface 200a. The reflective surface 200a of the dimming structure 200 can be used to reflect at least a portion of the light emitted by the target sub-pixel 101a towards the location of the splicing gap V, thereby increasing the amount of light at the location of the splicing gap V.
[0029] It should be noted that, as Figure 3As shown, the dimming structure 200 is located on the side of the target sub-pixel 101a that is away from the splicing gap V. That is, the orthographic projection of the dimming structure 200 on the display surface P of the display module does not coincide with the orthographic projection of the target sub-pixel 101a on the display surface P of the display module. In this way, the dimming structure 200 will not block the light emitted from the target sub-pixel 101a, ensuring that the image display in the display area M of the display screen 100 is not affected.
[0030] It should also be noted that the orthographic projection of the dimming structure 200 on the display surface P of the display module does not coincide with the orthographic projection of the other sub-pixels 101 in the display area M of the display screen 100, except for the target sub-pixel 101a, on the display surface P of the display module. In this way, the dimming structure 200 will not block the light emitted by the other sub-pixels 101, further ensuring that the display of the screen in the display area M of the display screen 100 will not be affected.
[0031] In this application, the dimming structure 200 can have two forms, which can guide the light emitted by the target sub-pixel 101a to the reflective surface 200a at the location of the splicing gap V.
[0032] In the first case, such as Figure 4 As shown, Figure 4 This is a cross-sectional view of another display module provided in this application embodiment. The reflective surface 200a of the dimming structure 200 is coated with a reflective coating 201. Here, the side of the reflective coating 201 facing the target sub-pixel 101a is the reflective surface 200a. In this way, the light emitted from the target sub-pixel 101a, after hitting the reflective surface 200a of the reflective coating 201, can be reflected by the reflective surface 200a of the reflective coating 201 to the splicing gap V.
[0033] It should be noted that the reflective coating 201 can be made of a metal material with high reflectivity, such as silver or aluminum, or it can be made of an inorganic non-metallic material with high reflectivity. This application embodiment does not specifically limit this.
[0034] It should also be noted that the dimming structure 200 may further include a support substrate 202. In the target direction X, the support substrate 202 may be located on the side of the target sub-pixel 101a away from the splicing gap V, and the reflective coating 201 may be located on the side of the support substrate 202 facing the target sub-pixel 101a. The side of the reflective coating 201 away from the support substrate 202 is the reflective surface 200a.
[0035] Here, the support substrate 202 can be made of resin material. In the process of preparing the dimming structure part 200, the support substrate 202 can be prepared first by coating and exposure process, and then the reflective material can be prepared on the support substrate 202 by vapor deposition process or atomic deposition process to form reflective coating 201.
[0036] In the second case, such as Figure 5 As shown, Figure 5 This is a cross-sectional view of another display module provided in the embodiments of this application. The display module may further include a filling portion 300. The filling portion 300 in the display module may be at least disposed on the side of the dimming structure portion 200 facing the splicing gap V in the target direction X, and may be in contact with the reflective surface 200a. Here, the refractive index of the filling portion 300 may be greater than the refractive index of the dimming structure 200.
[0037] In this way, the light emitted by the target sub-pixel 200a can be directed towards the filling part 300 after hitting the reflective surface 200a of the dimming structure 200. Since the refractive index of the filling part 300 is greater than that of the dimming structure 200, the light emitted by the target sub-pixel 101a and directed from the dimming structure 200 with a lower refractive index to the filling part 300 with a higher refractive index can converge, thus enabling the light to be directed towards the splicing gap V.
[0038] It should be noted that the filling portion 300 in the display module can be the portion of the cover layer 400 in the subsequent embodiment located between the dimming structure portion 200 and the splicing gap V in the target direction X.
[0039] Optional, such as Figure 4 As shown, the angle α between the reflective surface 200a of the dimming structure 200 and the bottom surface of the dimming structure 200 facing the display screen 100 can be less than or equal to 90°. Specifically, the angle α between the reflective surface 200a of the dimming structure 200 and the bottom surface of the dimming structure 200 facing the display screen 100 can be between 60° and 90°.
[0040] It should be noted that in the first case of reflective surface 200a, such as Figure 3 As shown, the angle α between the side of the support substrate 202 facing the splicing seam V and the bottom surface of the support substrate 202 facing the display screen 100 in the dimming structure 200 can be less than or equal to 90°. Thus, after the reflective coating 201 is deposited on the side of the support substrate 202 facing the splicing seam V, the angle α between the reflective surface 200a and the bottom surface of the dimming structure 200 facing the display screen 100 can be less than or equal to 90°.
[0041] It should also be noted that the support base 202 in the dimming structure 200 only needs to ensure that the angle between the side of the support base 202 facing the splicing gap V and the bottom surface of the support base 202 facing the display screen 100 is less than 90°. There is no restriction on the angle between the side of the support base 202 away from the splicing gap V and the bottom surface of the support base 202 facing the display screen 100. That is, the shape of the cross-section of the support base 100 under the target plane can be an isosceles trapezoid, a right trapezoid, or a triangle, etc., and this embodiment does not limit this. Here, the target plane can be perpendicular to the display surface P of the display module and parallel to the target direction X.
[0042] In the second optional implementation, such as Figure 6 As shown, Figure 6 This is a cross-sectional view of another display module provided in this application embodiment. The orthographic projection of the dimming structure 200 in the display module onto the display surface P of the display module can cover the orthographic projection of the splicing gap V onto the display surface P of the display module. Specifically, for the dimming structure 200 covering the splicing gap V, and the two display screens 100 located on both sides of the splicing gap V, the dimming structure 200 is used to converge at least the light emitted by the target sub-pixels 101a in the two display screens towards the splicing gap V, thereby increasing the amount of light at the location of the splicing gap V.
[0043] Optional, such as Figure 6 As shown, the dimming structure 200 in the display module may include a first dimming unit 203 and a second dimming unit 204 stacked in a direction perpendicular to the display surface P of the display module. The interface between the first dimming unit 203 and the second dimming unit 204 in the display module can be an arc-shaped surface, which can be used to converge at least a portion of the light emitted from the target sub-pixel 101a to the location of the splicing gap V. That is, after the light emitted from the target sub-pixel 101a is sequentially directed to the first dimming unit 203 and the second dimming unit 204, the arc-shaped surfaces of the first dimming unit 203 and the second dimming unit 204 can conduct the light to the splicing gap V, thereby converging the light to the splicing gap V.
[0044] Optionally, in a direction perpendicular to the display surface P of the display module, the first dimming unit 203 may be closer to the display screen 100 than the second dimming unit 204.
[0045] In one configuration, the first dimming unit 203 has a concave arc surface on the side facing away from the display screen 100, and at least a portion of the second dimming unit 204 is in contact with the concave arc surface of the first dimming unit 203, wherein the refractive index of the first dimming unit 203 is less than the refractive index of the second dimming unit 204. Thus, the light emitted from the target sub-pixel 101a can change its emission direction after passing through the contact interface between the first dimming unit 203 and the second dimming unit 204, converging towards the splicing seam V.
[0046] It should be noted that when the refractive index of the first dimming part 203 is less than that of the second dimming part 204, the refractive index of the first dimming part 203 can be between 1.38 and 1.7, and the refractive index of the second dimming part 204 can be between 2 and 4. Furthermore, the first dimming part 203 can be made of magnesium oxide, and the second dimming part 204 can be made of titanium dioxide. Alternatively, the first dimming part 203 can be made of methyl silicone resin, and the second dimming part 204 can be made of phenyl silicone resin.
[0047] In another configuration, the first dimming unit 203 has a curved convex surface on the side facing away from the display screen 100, and at least a portion of the second dimming unit 204 can be in contact with the curved convex surface of the first dimming unit 203, and the refractive index of the first dimming unit 203 can be greater than the refractive index of the second dimming unit 204. In this way, the light emitted from the target sub-pixel 101a, after passing through the contact interface between the first dimming unit 203 and the second dimming unit 204, can change its emission direction to converge towards the splicing seam V.
[0048] It should be noted that the arc-shaped concave surface of the first dimming part 203 can be prepared by a coating exposure process or by laser cutting.
[0049] Optional, such as Figure 6 As shown, for the dimming structure 200 covering the splicing gap V, and the two displays 100 located on both sides of the splicing gap V, the orthographic projection of the dimming structure 200 on the display surface P of the display module can cover the orthographic projection of the target sub-pixel 101a in the two displays 100 on the display surface P of the display module. This ensures that most of the light emitted by the target sub-pixel 101a can enter the dimming structure 200, so that it is directed towards the splicing gap V under the action of the dimming structure 200, further increasing the amount of light at the splicing gap V.
[0050] In this application, as Figure 7 As shown, Figure 7This is a cross-sectional view of another display module provided in this application embodiment. The display screen 100 in the display module may include: a support layer 102, a display panel 103, and a protective cover plate 104. The protective cover plate 104 in the display screen 100 may be located on the light-emitting side of the display panel 103, and the support layer 102 may be located on the side of the display panel 103 opposite to the protective cover plate 104. Here, the multiple sub-pixels 101 in the display area M of the display module may be located within the display surface 103, and the light-emitting side of the display panel 103 is the light-emitting side of the multiple sub-pixels 101.
[0051] The dimming structure 200 can be located on the side of the protective cover 104 opposite to the display panel 103, and the display module can further include a cover layer 400, which can cover the side of the dimming structure 200 opposite to the protective cover 400. Here, the cover layer 400 can ensure the flatness of the light-emitting side of the display module. It should be noted that the cover layer 400 can be manufactured using inkjet printing technology.
[0052] It should be noted that when the dimming structure 200 is located on the side of the protective cover 104 away from the display panel 103, multiple dimming structure 200s in the display module can be covered by the same cover layer 400; that is, the multiple dimming structure 200s and the cover layer 400 can be an integral structure. In this case, the multiple dimming structure 200s and the cover layer 400 can be manufactured separately to form a light path adjustment layer. After the multiple displays 100 are spliced into a display module, the light path adjustment layer can be directly pasted onto the protective cover 104 of the multiple displays 100.
[0053] Alternatively, when the dimming structure 200 is located on the side of the protective cover 104 away from the display panel 103, the display module may include multiple cover layers 400, each of which may correspond one-to-one with a multiple display screen 100. Each cover layer 400 may individually cover the dimming structure 200 on the side of the protective cover 104 of the corresponding display screen 100 away from the display panel 103.
[0054] In this way, each cover layer 400 and the corresponding dimming structure 200 can be manufactured and formed separately to form a light path adjustment layer. Then, the light path adjustment layer can be pasted onto the protective cover plate 104 of the corresponding display screen 100. Then, the display screens 100 with the light path adjustment layer can be spliced together to form a display module.
[0055] Optional, such as Figure 8 As shown, Figure 8This is a cross-sectional view of a display module according to another embodiment of this application. The display panel 103 in the display screen 100 may integrate an encapsulation layer 1031. The encapsulation layer 1031 may include: a first inorganic encapsulation layer 10311, an organic encapsulation layer 10312, and a second inorganic encapsulation layer 10313 stacked together. The first inorganic encapsulation layer 10311 is closer to the sub-pixel 101 than the second inorganic encapsulation layer 10313. The dimming structure 200 may be located between the first inorganic encapsulation layer 10311 and the organic encapsulation layer 10312.
[0056] Here, the encapsulation layer 1031 in the display panel 103 can encapsulate multiple sub-pixels 101 to prevent water and oxygen in the external environment from eroding the sub-pixels from the display side of the display module, thus ensuring that the display module can display the image normally.
[0057] It should be noted that a pixel definition layer 1032 may also be integrated within the display panel 103. The pixel definition layer 1032 has multiple pixel openings, and each of the multiple pixel openings corresponds to a multiple sub-pixels 101. The sub-pixels 101 can be located within the corresponding pixel openings.
[0058] It should also be noted that when the dimming structure 200 is located between the first infinite encapsulation layer 10311 and the organic encapsulation layer 10312, the display module no longer needs to include the cover layer 400, and the organic encapsulation layer 10312 can cover the dimming structure 200.
[0059] Furthermore, since the dimming structure 200 is located between the first non-polar encapsulation layer 10311 and the organic encapsulation layer 10312, the dimming structure 200 can be integrated into the display screen 100 during the manufacturing process. After the display screen 100 is manufactured, the dimming structure 200 is integrated within the display screen 100. In this way, by splicing multiple display screens 100 together, the display module of this application can be obtained.
[0060] The sub-pixels 101 in the display screen 100 can be driven to emit light by a driving circuit. The driving circuit drives multiple sub-pixels 101 to emit light of different colors and / or brightness, so that the display surface P of the display screen 100 can display the corresponding image.
[0061] In this application, the driving circuit can control the brightness of the light emitted by the target sub-pixel 101a, making it dimmer than the light emitted by other sub-pixels 101. In this way, during the display of images on multiple displays 100 of the display module, the brightness of the light can transition from the center of the display 100 to the splicing gap V by the light emitted by the target sub-pixel 101a, thereby improving the visual discontinuity for the user and enhancing the user's visual experience.
[0062] It should be noted that the driving circuit can control only the brightness of the light emitted by the target sub-pixel 101a to dim, so that the light emitted by the target sub-pixel 101a can play a transitional role and improve the user's visual experience. Alternatively, the driving circuit can control the light emitted by all sub-pixels 101, so that the brightness of the light gradually dims from the center of the display screen 100 to the splicing gap V, in order to improve the user's visual experience.
[0063] In this application, the implementation method of controlling the target sub-pixel 101a to dim the emitted light to improve the user's visual experience can be combined with the first or second optional implementation method in the above embodiments to further improve the user's visual experience. Furthermore, in this case, when the user views the image displayed by the display module at a distance greater than 2 meters, the user will not observe the splicing gap V.
[0064] In summary, this application provides a display module including multiple displays and multiple dimming structures. A seam is formed between any two adjacent displays, and the sub-pixel closest to the seam among the multiple sub-pixels within the display area of each display is the target sub-pixel. The dimming structure, located on the light-emitting side of the sub-pixel and positioned at the seam, can guide at least the light emitted by the target sub-pixel to the seam. Thus, while a user is viewing the images displayed on the multiple displays in the display module, the light guided by the dimming structure to the location of the seam can also enter the user's eye. This increases the amount of light at the seam location, thereby mitigating the visual disruption caused by the seam and improving the user's viewing experience.
[0065] This application also provides a display device, which may include a housing and a display module. The display module can be fixed inside the housing, and the display module can be the same as the one described in the above embodiments. The display device equipped with this display module can be a splicing display device, capable of large-area display. This display device can be used in studios, conference rooms, hospitals, shopping malls, etc.
[0066] It should be noted that the dimensions of layers and regions may be exaggerated in the accompanying drawings for clarity. Furthermore, it is understood that when an element or layer is referred to as being "on" another element or layer, it can be directly on the other element, or there may be intermediate layers. Additionally, it is understood that when an element or layer is referred to as being "below" another element or layer, it can be directly below the other element, or there may be more than one intermediate layer or element. Furthermore, it is also understood that when a layer or element is referred to as being "between" two layers or two elements, it can be the only layer between the two layers or two elements, or there may be more than one intermediate layer or element. Similar reference numerals throughout indicate similar elements.
[0067] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
