Description

Technical Field

[0001] This disclosure belongs to the field of display technology, specifically relating to a display screen and a display device. Background Technology

[0002] In related technologies, when multiple spliced ​​displays are displayed together, a seam area is generated at the splicing position. The brightness of the seam area is much lower than the display brightness of the light-emitting surface of the display, resulting in a poor overall display effect. Summary of the Invention

[0003] The purpose of this disclosure is to provide a display screen and a display device that can guide a portion of the light illuminating the color resist blocks from the splicing surface through a reflective layer disposed at an angle relative to the light-emitting surface of the display screen, thereby enhancing the intensity of the emitted light from the splicing surface of the display screen.

[0004] This disclosure provides a display screen, at least one side of which is a splicing surface. The display screen includes a color resist layer, which includes a plurality of color resist blocks arranged in an array.

[0005] Among the plurality of color resist blocks, the color resist block closest to the splicing surface is defined as the splicing color resist block. A light guide groove is formed in a local area of ​​the splicing color resist block. A reflective layer is disposed in the light guide groove. The reflective layer includes a first end and a second end opposite to each other. The second end is closer to the splicing surface than the first end, and the first end is closer to the light-incident side of the color resist layer of the display screen than the second end. The reflective layer is configured to guide part of the light illuminating the splicing color resist block out from the splicing surface.

[0006] In one exemplary embodiment of this disclosure, the reflective layer includes a plurality of spaced-apart light-transmitting holes that penetrate the reflective layer.

[0007] In one exemplary embodiment of this disclosure, the color resist blocks other than the spliced ​​color resist blocks among the plurality of color resist blocks are defined as normal color resist blocks; wherein,

[0008] In the direction perpendicular to the splicing surface: the size of the spliced ​​color resist block is larger than the size of the normal color resist block.

[0009] In one exemplary embodiment of this disclosure, in the direction perpendicular to the splicing surface: the size ratio of the normal color resist block to the spliced ​​color resist block is 1:2 to 1:3; and / or,

[0010] The area in the spliced ​​color resist block where the reflective layer is not provided is defined as the light-transmitting area; in the direction perpendicular to the splicing surface, the size ratio of the light-transmitting area to the size of the normal color resist block is 1:1.

[0011] This disclosure provides a display device, including a reflective structure and a plurality of displays as described above, wherein the plurality of displays are spliced ​​together, and there is a seam area between adjacent displays. The reflective structure is located in the seam area and is configured to guide light emitted from the splicing surfaces of two adjacent displays to the light-emitting surface of the display device.

[0012] In one exemplary embodiment of this disclosure, the display device includes a light filter, which is disposed on the light-emitting side of the reflective structure;

[0013] Specifically, on the light-emitting surface of the display device: the orthographic projection of the filter portion covers the orthographic projection of the seam area and the orthographic projection of the edge portion of the adjacent splicing color resist block.

[0014] In an exemplary embodiment of this disclosure, the filter section has a first filter area and a second filter area, and the splicing color resist block of the display screen adjacent to the first filter area is defined as the first splicing color resist block, and the splicing color resist block of the display screen adjacent to the second filter area is defined as the second splicing color resist block.

[0015] The first filter area has the same color as the first spliced ​​color resist block and covers the edge portion of the first spliced ​​color resist block;

[0016] The second filter area has the same color as the second spliced ​​color resist block and covers the edge portion of the second spliced ​​color resist block.

[0017] In one exemplary embodiment of this disclosure, the light-filtering portion further includes a light-shielding area located between the first light-filtering area and the second light-filtering area, the light-shielding area being configured to block light; and / or,

[0018] The orthographic projection of the first filter area onto the first spliced ​​color resist block can cover the corresponding light guide groove; the orthographic projection of the second filter area onto the second spliced ​​color resist block can cover the corresponding light guide groove.

[0019] In one exemplary embodiment of this disclosure, the reflective structure includes:

[0020] The first reflective surface faces the first spliced ​​color resist block, its top edge is connected to the side of the first filter area near the second filter area, and its top edge is not lower than the top surface of the adjacent color resist layer, and the bottom edge of the first reflective surface is not higher than the bottom surface of the adjacent color resist layer.

[0021] The second reflective surface faces the second spliced ​​color resist block, its top edge is connected to the side of the second filter area near the first filter area, and its top edge is not lower than the top surface of the adjacent color resist layer, and the bottom edge of the second reflective surface is not higher than the bottom surface of the adjacent color resist layer.

[0022] The first reflective surface and the second reflective surface are configured to guide the light emitted from the two adjacent splicing surfaces to the light-emitting surface of the display device.

[0023] In one exemplary embodiment of this disclosure, the first reflective surface is parallel to a corresponding adjacent reflective layer, and the second reflective surface is parallel to another corresponding adjacent reflective layer; and / or,

[0024] The angle between the first reflective surface and the second reflective surface and the light-emitting surface of the display device ranges from 45° to 75°.

[0025] The technical solution provided in this disclosure has at least the following advantages:

[0026] This embodiment of the present disclosure provides a light guide groove within the splicing color resist block and a reflective layer disposed at an angle relative to the light-emitting surface of the display screen within the light guide groove. The reflective layer includes a first end and a second end opposite to each other, with the second end being closer to the splicing surface than the first end. By making the first end closer to the light-incident side of the color resist layer of the display screen than the second end, the reflective layer can guide part of the light irradiated onto the splicing color resist block from the splicing surface, thereby enhancing the intensity of the emitted light from the splicing surface of the display screen.

[0027] When multiple displays are spliced ​​together, the brightness at the seam between adjacent displays can be increased, reducing the difference in brightness between the seam and adjacent displays. This can improve the problem of black borders appearing at the seams of multiple spliced ​​displays, and enhance the overall display effect of the large display screen formed by splicing multiple displays.

[0028] In addition, the areas in the splicing color resist blocks without a reflective layer are configured to filter the display light source that shines on the color resist layer, and to allow at least a portion of the filtered light to exit onto the light-emitting surface of the display screen, so as to achieve the display of a specific color image.

[0029] Other features and advantages of this disclosure will become apparent from the following detailed description, or may be learned in part by practice of this disclosure.

[0030] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0044] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

[0045] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0046] The present disclosure will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0047] With the continuous development of display technology, the application of displays is becoming increasingly widespread, not only in televisions, monitors, industrial displays, and medical displays, but also increasingly in outdoor displays. With the rapid development of the outdoor display market, large-size, high-resolution products are becoming the development direction for outdoor displays.

[0048] Traditional liquid crystal displays (LCDs) offer advantages such as low cost and high resolution, making them suitable for outdoor displays. This is achieved by splicing multiple LCD panels together to create a large-screen display. However, when multiple LCD panels are spliced ​​together, seams appear between adjacent panels, affecting the visual effect.

[0049] To eliminate seams, some technologies involve placing LED display panels between adjacent LCD panels. However, adding LED display panels increases the overall structural thickness and complexity, raises power consumption, and worsens display stability with each additional LED panel.

[0050] In addition, splicing screens will generally be relatively misaligned during use. The degree of misalignment may vary in different locations, and the weakening and compensation of the splicing seams that were originally used will change after the misalignment.

[0051] like Figures 1 to 3 As shown, a large-size display device 200 is composed of multiple spliced ​​display screens 100. The splicing seam sizes between each display screen 100 are assumed to be a and b. After the splicing screen has been used for a period of time, due to mechanical vibration or aging, different relative displacements will occur between each display screen 100. At this time, the distance between the splicing seams will change to ax or bx (x can be 1, 2, etc.).

[0052] Because video walls have seams around their edges, the display effect at the seams will change significantly when the seam distance changes. Different seams on the entire 100-screen display will have different display effects, resulting in a serious uneven overall display.

[0053] To solve the above technical problems, such as Figures 4 to 5 As shown, this disclosure provides a display screen 100, at least one side of which is a splicing surface, configured to be spliced ​​with the splicing surfaces of other display screens 100.

[0054] For example, when the display screen 100 is rectangular, the display screen 100 may include one, two, three or four splicing surfaces, and the specific number of splicing surfaces can be determined according to the actual situation.

[0055] The display screen 100 includes a color resist layer 1, which includes a plurality of color resist blocks configured to filter light so that light of a specific color can pass through, and the plurality of color resist blocks are arranged in an array.

[0056] Among them, the color resist block closest to the splicing surface among multiple color resist blocks can be defined as splicing color resist block 11. A light guide groove 13 is provided in a local area of ​​the splicing color resist block 11, and a reflective layer 14 is provided in the light guide groove 13.

[0057] The reflective layer 14 includes a first end and a second end opposite to each other. The second end is closer to the splicing surface than the first end, and the first end is closer to the light-incident side of the color resist layer 1 than the second end.

[0058] The reflective layer 14 is configured to direct a portion of the light illuminating the splicing color resist block 11 from the splicing surface, thereby enhancing the intensity of the emitted light from the splicing surface of the display screen 100. When multiple displays 100 are spliced ​​together, the brightness at the seam between adjacent displays 100 can be increased, reducing the difference between the brightness at the seam and the brightness of adjacent displays 100. This can improve the problem of black borders appearing at the seams of multiple spliced ​​displays 100, and improve the display effect of the entire large display screen formed after multiple displays 100 are spliced ​​together.

[0059] The area in the splicing color resist block 11 without the reflective layer 14 is configured to filter the display light source that shines on the color resist layer 1, and to allow at least a portion of the filtered light to be emitted to the light-emitting surface of the display screen 100, so as to achieve the display of a specific color of the display screen 100.

[0060] For example, when the color resist layer 1 of the display screen 100 has multiple color resist blocks, and the multiple color resist blocks are arranged in a direction perpendicular to the splicing surface, and the multiple color resist blocks are configured to allow light of different colors to pass through, while the reflective layer 14 in the splicing color resist block 11 can be used to guide part of the light irradiated to the splicing color resist block 11 from the splicing surface, the area in the splicing color resist block 11 without the reflective layer 14 can also be used to filter the light emitted to the light-emitting surface of the display screen 100. Thus, each color resist block in the display screen 100 can guide at least part of the filtered light to the light-emitting surface of the display screen 100 to achieve color display of the display screen 100.

[0061] like Figure 6 As shown, the area in the splicing color resist block 11 without a reflective layer 14 is defined as the light-transmitting area, and the area in the splicing color resist block 11 with a reflective layer 14 is defined as the reflective area. On the light-emitting surface of the display screen 100, there is no overlap between the orthographic projection of the light-transmitting area and the orthographic projection of the reflective area.

[0062] In some embodiments, the reflective layer 14 may include a plurality of spaced-apart light-transmitting holes 141. The light-transmitting holes 141 penetrate the reflective layer 14, and the display light source can be emitted to the light-emitting surface of the display screen 100 through the light-transmitting holes 141. This can improve the display brightness at the corresponding positions of the light-emitting surface and the reflective area of ​​the display screen 100, reduce the difference in display brightness between the corresponding positions of the light-emitting surface and the reflective area and the corresponding positions of the light-transmitting area, and thus improve the overall display brightness of the display screen 100 and enhance the display effect.

[0063] Furthermore, the size of the light-transmitting aperture 141 can be no less than 1μm to facilitate the passage of light.

[0064] The ratio between the area of ​​all the light-transmitting holes 141 in the reflective layer 14 and the area of ​​the region in the reflective layer 14 used for reflecting light can be 1:2. This ensures that enough light is reflected through the reflective layer 14 and exported from the splicing surface, while also ensuring that the reflective area of ​​the splicing color resist block 11 has enough light to be emitted to the light-emitting surface of the display screen 100.

[0065] In some embodiments, the light guide groove 13 may be formed on at least a portion of the surface of the splicing color resist block 11. For example, the light guide groove 13 may be formed on the side of the splicing color resist block 11 near the splicing surface, or on the side of the splicing color resist block 11 opposite to the light-emitting surface of the display screen 100, or on at least one of the sides of the splicing color resist block 11 near the light-emitting surface of the display screen 100. However, it is not limited to this; the light guide groove 13 may also be spaced apart from the outer surface of the splicing color resist block 11, depending on the actual situation.

[0066] For example, the light guide groove 13 can be simultaneously opened on the side of the splicing color resist block 11 near the splicing surface and on the side of the splicing color resist block 11 away from the light-emitting surface of the display screen 100. In this case, the light-transmitting area and the reflective area are located on the side of the light-transmitting area near the splicing surface.

[0067] In some embodiments, the color resist blocks other than the spliced ​​color resist block 11 among the plurality of color resist blocks are defined as normal color resist blocks 12. The size of the spliced ​​color resist block 11 in the first direction is larger than the size of the normal color resist block 12 in the first direction, and the first direction is perpendicular to the splicing surface.

[0068] It should be noted that when the display screen 100 includes multiple splicing surfaces, the first direction refers to the direction perpendicular to the corresponding adjacent splicing surface in the splicing color resist block 11.

[0069] This disclosure makes the size of the splicing color resist block 11 larger than that of the normal color resist block 12 in the first direction, so that the brightness of the light illuminating the splicing color resist block 11 is greater than that of the light illuminating the normal color resist block 12. Thus, while some of the light on the splicing color resist block 11 is reflected to the splicing surface through the reflective layer 14, it can also ensure that the splicing color resist block 11 has enough light to be introduced to the light-emitting surface of the display screen 100 for display.

[0070] For example, in the first direction, the size ratio of the normal color resist block 12 to the splicing color resist block 11 can be 1:2 to 1:3 to ensure that the splicing color resist block 11 has enough light to be introduced to the light-emitting surface of the display screen 100 and to the splicing surface. However, it is not limited to this; the size ratio of the normal color resist block 12 to the splicing color resist block 11 can also be other values ​​besides 1:2 to 1:3, and can be set according to the actual situation.

[0071] For example, among the red, blue, and green color resist blocks, considering that the blue color resist block has the lowest luminous efficiency and short decay life, it is generally set to be larger. Therefore, it is possible to consider setting the blue color resist block as a spliced ​​color resist block 11 with a size larger than the normal color resist block 12.

[0072] In some embodiments, in the direction perpendicular to the splicing surface, the ratio of the size of the light-transmitting area to the size of the normal color resist block 12 is 1:1, to ensure that the light filtered by the light-transmitting area of ​​the splicing color resist block 11 can be mixed with the light filtered by the normal color resist block 12 to adjust the display image on the display screen 100. Within the allowable error range, the ratio of the size of the light-transmitting area to the size of the normal color resist block 12 can be appropriately adjusted based on the 1:1 ratio.

[0073] It should be noted that after the size of the color resist block in this disclosure is adjusted, the overall size of the color resist layer 1 in the display screen 100 remains unchanged.

[0074] For example, when the color resist layer 1 in the related technology includes multiple arrayed color resist units, and each color resist unit includes red, green, and blue color resist blocks arranged sequentially along a direction perpendicular to the splicing surface, and the length of the three color resist blocks in the direction perpendicular to the splicing surface is P, in this disclosure, the lengths of the three color resist blocks in the direction perpendicular to the splicing surface can be adjusted to (3 / 5)×P, (3 / 5)×P, and (9 / 5)×P respectively, while the overall length of the color resist unit in the direction perpendicular to the splicing surface remains unchanged, thereby keeping the overall size of the color resist layer 1 unchanged. For details, please refer to... Figures 4 to 5 As shown.

[0075] In some embodiments, the color resist layer 1 may include a barrier 15 located between two adjacent color resist blocks. The barrier 15 has light-blocking properties to improve the problem of light crosstalk when the transmitted light colors are different between two adjacent color resist blocks.

[0076] In some embodiments, the display screen 100 may include a liquid crystal layer 2 and a driving backplate, the liquid crystal layer 2 and the driving backplate being located on the side of the color resist layer 1 away from the light-emitting surface of the display screen 100, and the liquid crystal layer 2 being located on the side of the driving backplate close to the color resist layer 1.

[0077] Thin-film transistors can be disposed on the driving backplane. The thin-film transistors are configured to adjust the electric field on the liquid crystal layer 2, thereby driving the deflection angle of the liquid crystal in the liquid crystal layer 2.

[0078] Furthermore, the display screen 100 may include multiple pixel areas, and multiple thin-film transistors may be disposed on the driving backplane. The multiple thin-film transistors may correspond one-to-one with the pixel areas to realize the partition control of the display screen 100 displaying the image.

[0079] In some embodiments, the display screen 100 can display images through its own light-emitting structure. In this case, the display light source of the display screen 100 comes from the light-emitting structure, and the side of the color resist layer 1 closest to the light-emitting structure is its light-incident side.

[0080] Specifically, the display screen 100 may include a backlight module 4, which is disposed on the side of the color resist layer 1 away from the light-emitting surface of the display screen 100, and is configured to provide a light source to the color resist layer 1. That is, the backlight module 4 can provide a display light source for the display screen 100.

[0081] The backlight module 4 can be a mini LED (submillimeter-sized light-emitting diode) backlight module 4. The size of the LED chips in the mini LED backlight module 4 can be reduced to less than 100μm, which facilitates the fabrication of high-density LED arrays. Using the mini LED backlight module 4 to provide a display light source for the display screen 100 enables precise control of local areas of the display light source, improving the display contrast and dynamic range of the display screen 100. Mini LED display technology combines the advantages of LCD (liquid crystal display 100) and OLED (organic light-emitting display 100). By using a large number of smaller LED chips, more screen backlight zones can be achieved, resulting in higher peak brightness and better color performance, while also offering advantages in cost and lifespan compared to OLED. However, this is not the only possibility; the backlight module 4 in this disclosure can also be any other backlight module 4 besides the mini LED backlight module 4, depending on the specific circumstances.

[0082] In this disclosure, the length of the reflective layer 14 can be less than the length of the splicing color block 11 in the direction perpendicular to the splicing surface. While the light emitted from the backlight module 4 is emitted to the splicing surface through the reflective layer 14, it can also be filtered through the area (i.e., the light-transmitting area) in the splicing color block 11 where the reflective layer 14 is not provided, and the filtered light is emitted to the light-emitting surface of the display screen 100 to realize the display of the display screen 100.

[0083] For example, such as Figure 5 As shown, the light-transmitting area can be located on the side of the reflective layer 14 away from the splicing screen, so as to facilitate the mixing between the light filtered by the light-transmitting area and the light filtered by the normal color resist block 12, thereby realizing the adjustment of the color of the display screen 100. At the same time, the reflective layer 14 is set close to the splicing surface, which can also facilitate the shortening of the light path of the light reflected by the reflective layer 14 to the splicing surface, thereby reducing light loss.

[0084] Continue to refer to Figure 5As shown in this disclosure, the light guide groove 13 can be simultaneously formed on the side of the splicing color resist block 11 near the splicing surface and on the side of the splicing color resist block 11 near the backlight module 4. At this time, the light from the backlight module 4 can directly irradiate the reflective layer 14 without passing through the splicing color resist block 11, and be reflected by the reflective layer 14 to the splicing surface of the display screen 100. This improves the problem that when the splicing color resist block 11 is provided on the side of the reflective layer 14 near the backlight module 4, the splicing color resist block 11 increases the light loss. In this way, the light irradiated to the reflective layer 14 can be increased, and the brightness of the light reflected to the splicing surface can be increased.

[0085] The side of the first end of the reflective layer 14 that faces away from the light-emitting surface of the display screen 100 can be flush with the side of the splicing color resist block 11 that faces away from the light-emitting surface of the display screen 100. However, it is not limited to this. The side of the first end of the reflective layer 14 that faces away from the light-emitting surface of the display screen 100 can also form a height difference with the side of the splicing color resist block 11 that faces away from the light-emitting surface of the display screen 100. That is, the side of the first end of the reflective layer 14 that faces away from the light-emitting surface of the display screen 100 is closer to the light-emitting surface of the display screen 100 than the side of the splicing color resist block 11 that faces away from the light-emitting surface of the display screen 100.

[0086] Furthermore, the thickness of the splicing color resist block 11 (i.e., the length perpendicular to the light-emitting direction of the display screen 100) is defined as D. When the first end of the reflective layer 14 facing away from the light-emitting surface of the display screen 100 and the splicing color resist block 11 facing away from the light-emitting surface of the display screen 100 form a height difference, the range of the height difference between the first end of the reflective layer 14 facing away from the light-emitting surface of the display screen 100 and the splicing color resist block 11 facing away from the light-emitting surface of the display screen 100 can be: (1 / 3)×D~(1 / 2)×D.

[0087] When the display screen 100 in this disclosure has a liquid crystal layer 2 and a driving backplate, the liquid crystal layer 2 and the driving backplate may be located between the backlight module 4 and the color resist layer 1.

[0088] In this disclosure, when the reflective layer 14 has multiple light-transmitting holes 141, the light emitted from the backlight module 4 can be emitted to the light-emitting surface of the display screen 100 through the light-transmitting holes 141, thereby improving the display brightness of the light-emitting surface of the display screen 100 and the corresponding position of the reflective area.

[0089] In some embodiments, the display screen 100 can also display images by reflecting ambient light. In this case, the display light source of the display screen 100 comes from ambient light, and the side of the color resist layer 1 closest to the light-emitting surface of the display screen 100 is its light-incident side. At least part of the ambient light illuminating the splicing color resist block 11 is reflected by the reflective layer 14 and then emitted onto the splicing surface.

[0090] In this disclosure, the display screen 100 may further include a reflective layer disposed on the side of the color resist layer 1 away from the light-emitting surface of the display screen 100, and configured to reflect a portion of the ambient light illuminating the color resist layer 1 to the light-emitting surface of the display screen 100.

[0091] For example, the orthogonal projection of the reflective layer onto the color resist layer 1 can at least cover the color resist block.

[0092] In some embodiments, the light guide groove 13 in the splicing color resist block 11 can be made by nanoimprinting technology or vapor deposition etching process.

[0093] For example, such as Figure 7 As shown, when the light guide groove 13 in the spliced ​​color resist block 11 is fabricated using nanoimprint lithography, the fabrication process may include: Step 1, fabrication of the imprint film 6: Using methods such as electron beam etching, an imprint film 6 with a specific micro / nano structure is fabricated on silicon or other substrates. Since the diffraction limit of electrons is much smaller than that of photons, the imprint film 6 prepared by electron beam etching can achieve a resolution much higher than that of photolithography. Step 2, color resist film formation (e.g. Figure 7 7a): On the glass substrate 5, the barrier 15 is first fabricated to separate different color resist blocks and to block light. Then, using inkjet printing or other methods, at least one color resist material 17 of blue, red, green, etc., is coated on the area between the barrier 15 to form a flat color resist layer 1. Step 3: Imprinting (e.g., Figure 7 (7b) First, a layer of photoresist is coated on the surface of the color resist material 17 and the barrier 15 as the imprinting medium layer. Then, the imprint film 6 with micro / nano structures is aligned with the color resist material 17 and pressed down. By applying pressure, the micro / nano structures on the template are transferred into the photoresist. During this process, it is important to ensure that the photoresist is not completely pressed through, leaving a thin layer to prevent direct contact between the template and the glass, thus preventing scratches and damage to the template. Step 4: Demolding (e.g.) Figure 7 Step 7c): First, use ultraviolet light to cure the photoresist, fixing the micro / nano structure formed by imprinting. Then, lift the imprint 6 upwards and detach it from the glass substrate 5. At this time, the micro / nano structure of the template has been replicated on the photoresist, forming an undulating structure. The part of the color resist material 17 covered by photoresist also forms a corresponding concave-convex contour. Step 5: Reactive ion etching to remove residual photoresist ( Figure 7 (7d) Using reactive ion etching (RIE) or similar methods, the thin layer of photoresist remaining after imprinting is removed, exposing the surface of the underlying color resist material 17. Using the photoresist as a mask, the exposed color resist material 17 is etched to transfer the micro / nano structure on the photoresist onto the color resist material 17. After etching, all remaining photoresist is removed, finally obtaining a color resist block with micro / nano structures, that is, fabricating the spliced ​​color resist block 11 with light guide groove 13 as disclosed in this disclosure, wherein the micro / nano structure of the imprinted film 6 is adapted to the shape of the light guide groove 13.

[0094] In some embodiments, a planarization layer 16 may also be provided in the light guide groove 13. The planarization layer 16 is transparent and can fill the gap area in the light guide groove 13 except for the reflective layer 14, so as to improve the stability of the reflective layer 14 installed in the light guide groove 13.

[0095] like Figure 8 As shown, a coating can be applied to the spliced ​​color resist block 11 with light guide groove 13 as described above; that is, a reflective layer 14 can be deposited on the inner wall of the light guide groove 13 of the spliced ​​color resist block 11. Next, the reflective layer 14 can be etched to form a plurality of spaced light-transmitting holes 141. Finally, a light-transmitting material can be filled into the light guide groove 13 to form a planarization layer 16, which can fill the void area in the light guide groove 13 except for the reflective layer 14.

[0096] For example, when the light guide groove 13 is located on the side of the splicing color resist block 11 that is away from the light-emitting surface of the display screen 100, by setting the flat layer 16, the support for the reflective layer 14 and the corresponding area of ​​the splicing color resist block 11 can be strengthened, thereby improving the stability of the installation of the splicing color resist block 11.

[0097] like Figure 6 As shown, in some embodiments, the angle θ1 between the reflective layer 14 and the light-emitting surface of the display screen 100 can be in the range of 45°~75°.

[0098] For example, the angle θ1 between the reflective layer 14 and the light-emitting surface of the display screen 100 can be 45°, 50°, 55°, 60°, 65°, 70°, 75°, etc., and can be set according to the actual situation.

[0099] This disclosure improves the problem that when the angle between the reflective layer 14 and the light-emitting surface of the display screen 100 is less than 45°, the displacement of the reflected light is not obvious, resulting in less reflected light being exported from the splicing surface. At the same time, it can also improve the problem that when the angle between the reflective layer 14 and the light-emitting surface of the display screen 100 is greater than 75°, the installation stability of the reflective layer 14 is poor due to the large angle.

[0100] like Figures 9 to 10As shown, this disclosure also provides a display device 200, which may include a reflective structure and a plurality of displays 100 as described above. The plurality of displays 100 are spliced ​​together, and the splicing surfaces of adjacent displays 100 in the display device 200 are opposite each other. There is a seam area between adjacent displays 100, and the reflective structure is located in the seam area. The reflective structure is configured to guide the light emitted from the splicing surfaces of the two adjacent displays 100 to the light-emitting surface of the display device 200, thereby improving the display brightness of the light-emitting surface of the display device 200 in the seam area and improving the black border problem that appears in the seam area of ​​the display device 200.

[0101] It should be noted that the "light emitted from the splicing surface" mentioned above refers to the light reflected by the reflective layer 14 in the splicing color resist block 11 and emitted from the splicing surface.

[0102] In some embodiments, the display device 200 may include a light filter, which is disposed on the light-emitting side of the reflective structure and configured to filter light while allowing light of a specific color to pass through. The orthographic projection of the light filter onto the light-emitting surface of the display device 200 can completely cover the orthographic projection of the seam area onto the light-emitting surface of the display device 200, thereby enabling the display device 200 to display a specific color image at the corresponding position in the seam area on the light-emitting surface.

[0103] Furthermore, the orthographic projection of the filter on the light-emitting surface of the display device 200 can also cover the orthographic projection of the edge portion of the adjacent splicing color resist block 11 on the light-emitting surface of the display device 200. When relative displacement occurs between adjacent display screens 100, causing a change in the size of the splicing area, the orthographic projection of the filter on the light-emitting surface of the display device 200 can always completely block the orthographic projection of the corresponding splicing area on the light-emitting surface of the display device 200, thereby allowing the filter to always adjust the image display effect at the corresponding position of the splicing area on the light-emitting surface of the display device 200.

[0104] In this disclosure, the display device 200 may include a plurality of light-filtering units, each of which corresponds one-to-one with a seam area, thereby allowing adjustment of the display effect of each seam area on the light-emitting surface of the display device 200.

[0105] In some embodiments, the light filtering section may include a first light filtering area 71 and a second light filtering area 72, the arrangement direction of the first light filtering area 71 and the second light filtering area 72 being the same as the arrangement direction of two adjacent display screens 100. The splicing color resist block 11 of the display screen 100 adjacent to the first light filtering area 71 is defined as the first splicing color resist block 111, and the splicing color resist block 11 of the display screen 100 adjacent to the second light filtering area 72 is defined as the second splicing color resist block 112.

[0106] In this disclosure, the first filter area 71 has the same color as the first splicing color block 111, and the second filter area 72 has the same color as the second splicing color block 112. This allows the color of the image displayed on the light-emitting surface of the display device 200 in the area corresponding to the splicing seam to be the same as the colors of the adjacent first splicing color block 111 and second splicing color block 112, achieving a natural color transition between the splicing seam and the adjacent display screen 100, and improving the problem of visual discontinuity between the display device 200 and the display screen 100.

[0107] In the filtering section, the first filtering area 71 can cover the edge portion of the first splicing color resist block 111, and the second filtering area 72 can cover the edge portion of the second splicing color resist block 112. When the relative displacement between adjacent displays 100 causes a change in the size of the splicing seam area, the orthographic projection of the first filtering area 71 on the light-emitting surface of the display device 200 always overlaps with the orthographic projection of the first splicing color resist block 111 on the light-emitting surface of the display device 200, and the orthographic projection of the second filtering area 72 on the light-emitting surface of the display device 200 always overlaps with the orthographic projection of the second splicing color resist block 112 on the light-emitting surface of the display device 200. Thus, the first filtering area 71 and the second filtering area 72 can achieve a natural color transition between the splicing seam area and the adjacent displays 100, improve the problem of visual discontinuity between the display device 200 and the display 100 in the splicing seam area, and compensate for the difference in display effect caused by the change in the size of the splicing seam area.

[0108] Furthermore, the orthographic projection of the first filter area 71 on the first splicing color resist block 111 can cover the corresponding light guide groove 13, and the orthographic projection of the second filter area 72 on the second splicing color resist block 112 can cover the corresponding light guide groove 13, so as to increase the filtering range of the first filter area 71 and the second filter area 72, improve the situation where some reflected light is placed directly on the light-emitting surface of the display device 200 without color filtering, and thus improve the display effect of the display device 200.

[0109] Furthermore, it should be noted that the thickness of the color resist material 17 at the location where the light guide groove 13 is provided on the splicing color resist block 11 is smaller than that at other locations, resulting in a weakened color filtering effect. This disclosure increases the thickness of the color resist material 17 at the location corresponding to the splicing color resist block 11 on the light-emitting surface of the display device 200 by ensuring that the orthogonal projections of the first filter area 71 and the second filter area 72 on the corresponding adjacent splicing color resist block 11 cover the corresponding light guide groove 13. This improves the color filtering effect and simultaneously enhances the overall display effect of the display device 200.

[0110] In some embodiments, the light-filtering unit may further include a light-shielding area 73, which is located between the first light-filtering area 71 and the second light-filtering area 72, and is configured to block light. When the colors of two adjacent color resist blocks 11 in two adjacent displays 100 are different, the light-shielding area 73 can improve the problem of crosstalk between the light from the first light-filtering area 71 and the light from the second light-filtering area 72, thereby improving the image purity and contrast of the light-emitting surface of the display device 200.

[0111] The orthographic projection of the shading area 73 onto the seam area can be located at the center of the seam area, but it is not limited to this. The orthographic projection of the shading area 73 onto the seam area can also be located in other areas besides the center of the seam area, depending on the actual situation.

[0112] Furthermore, the length of the seam area between the displays 100 in the display device 200 before relative displacement occurs is defined as m in the arrangement direction of two adjacent displays 100. The length of the light-shielding area 73 in the arrangement direction of two adjacent displays 100 in this disclosure can be (1 / 5) × m, in order to improve the problem that the anti-crosstalk effect of the light-shielding area 73 is weakened due to the excessively small length of the light-shielding area 73, and reduce the risk of crosstalk between the light from the first filter area 71 and the light from the second filter area 72 when the colors of the light from the first filter area 71 and the light from the second filter area 72 are different.

[0113] In some embodiments, the reflective structure may include a first reflective surface 74 and a second reflective surface 75. The first reflective surface 74 faces the first splicing color resist block 111, and the second reflective surface 75 faces the second splicing color resist block 112. The first reflective surface 74 and the second reflective surface 75 are configured to guide the light emitted from the splicing surface of two adjacent display screens 100 to the light-emitting surface of the display device 200.

[0114] Specifically, the first reflective surface 74 can guide the light emitted from the adjacent splicing surface to the first filter area 71, and after being filtered by the first filter area 71, it is emitted to the light-emitting surface of the display device 200. The second reflective surface 75 can guide the light emitted from the adjacent splicing surface to the second filter area 72, and after being filtered by the second filter area 72, it is emitted to the light-emitting surface of the display device 200.

[0115] like Figure 9As shown in this disclosure, the top edge of the first reflective surface 74 (that is, the side of the first reflective surface 74 near the light-emitting surface of the display device 200) can be connected to the side of the first filter area 71 near the second filter area 72, and the top edge of the second reflective surface 75 (that is, the side of the second reflective surface 75 near the light-emitting surface of the display device 200) can be connected to the side of the second filter area 72 near the first filter area 71. By isolating the light emitted from the two adjacent splicing surfaces through the first reflective surface 74 and the second reflective surface 75, the crosstalk between the light emitted from the two adjacent splicing surfaces can be improved. At the same time, the distance between the top edge of the first reflective surface 74, the top edge of the second reflective surface 75 and the corresponding adjacent splicing surfaces can be increased, thereby increasing the filtering range of the filter part in the splicing area and improving the overall display effect of the display device 200.

[0116] However, this is not the only possibility. The top edge of the first reflective surface 74 and the side edge of the first filter area 71 near the second filter area 72 can also be spaced apart, and the top edge of the second reflective surface 75 and the side edge of the second filter area 72 near the first filter area 71 can also be spaced apart.

[0117] Specifically, the distance between the top edge of the first reflective surface 74 and the side edge of the first filter area 71 near the second filter area 72 can be 1 μm, and the distance between the top edge of the second reflective surface 75 and the side edge of the second filter area 72 near the first filter area 71 can be 1 μm.

[0118] In this configuration, the top edge of the first reflective surface 74 (i.e., the side of the first reflective surface 74 closest to the light-emitting surface of the display device 200) can abut against the bottom surface of the first filter area 71 (i.e., the side of the first filter area 71 opposite to the light-emitting surface of the display device 200), and the top edge of the second reflective surface 75 (i.e., the side of the second reflective surface 75 closest to the light-emitting surface of the display device 200) can abut against the bottom surface of the second filter area 72 (i.e., the side of the second filter area 72 opposite to the light-emitting surface of the display device 200). Alternatively, the top edge of the first reflective surface 74 can abut against the bottom surface of the light-shielding area 73 (i.e., the side of the light-shielding area 73 opposite to the light-emitting surface of the display device 200), and the top edge of the second reflective surface 75 can abut against the bottom surface of the light-shielding area 73, with the first reflective surface 74 located on the side of the second reflective surface 75 closest to the first filter area 71.

[0119] In this disclosure, the top edge of the first reflective surface 74 may not be lower than the top surface of the adjacent color resist layer 1 (that is, the side of the color resist layer 1 that is close to the light-emitting surface of the display device 200), and the bottom edge of the first reflective surface 74 (that is, the side of the first reflective surface 74 that is far away from the light-emitting surface of the display device 200) may not be higher than the bottom surface of the adjacent color resist layer 1 (that is, the side of the color resist layer 1 that is far away from the light-emitting surface of the display device 200), so as to increase the area of ​​the first reflective surface 74, thereby reflecting more light emitted from the splicing surface, so as to improve the brightness of the light emitted from the first filter area 71. The top edge of the second reflective surface 75 may not be lower than the top surface of the adjacent color resist layer 1, and the bottom edge of the second reflective surface 75 (that is, the side of the second reflective surface 75 away from the light-emitting surface of the display device 200) may not be higher than the bottom surface of the adjacent color resist layer 1, so as to increase the area of ​​the second reflective surface 75, thereby reflecting more light emitted from the splicing surface, thereby increasing the brightness of the light emitted from the second filter area 72, and thus increasing the display brightness at the corresponding position of the light-emitting surface of the display device 200 and the splicing area, improving the problem of black edges appearing at the splicing area position under the display device 200.

[0120] In some embodiments, the display device 200 may further include a support structure 76, which is at least partially located within the seam area. The top surface of the support structure 76 (the side of the support structure 76 close to the light-emitting surface of the display device 200) abuts against the bottom surface of the filter (the side of the filter facing away from the light-emitting surface of the display device 200) to be configured to support the filter, thereby improving the problem of the filter collapsing in the seam area and extending the service life of the filter.

[0121] When the support structure 76 is located between the first reflective surface 74 and the corresponding adjacent color blocking block 11, and / or when the support structure 76 is located between the second reflective surface 75 and the corresponding adjacent color blocking block 11, the support structure 76 is light-transmitting to prevent the support structure 76 from obstructing the light emitted from the splicing surface onto the reflective structure.

[0122] For example, the reflective structure can be embedded entirely within the support structure 76, so that the support structure 76 can isolate the reflective structure from the adjacent display screen 100, thereby reducing the risk of damage caused by squeezing or collision between the reflective structure and the display screen 100.

[0123] The reflective structure and the support structure 76 together can directly abut against the adjacent display screen 100 (that is, against the adjacent splicing surface). For example, when the reflective structure is embedded in the support structure 76, the support structure 76 can directly abut against the adjacent display screen 100.

[0124] However, this is not the only possibility. The reflective structure and the support structure 76 can also be spaced apart from the adjacent display screen 100. The spacing between the reflective structure and the support structure 76 and the adjacent display screen 100 can be no more than 1 μm to improve the utilization rate of light emitted from the splicing surface.

[0125] Furthermore, the top surface of the support structure 76 can be flush with the light-emitting surfaces of the two adjacent displays 100, and the bottom surface of the filter can abut against the light-emitting surfaces of the two adjacent displays 100, thereby increasing the support area of ​​the filter and reducing the risk of bending and deformation of the filter.

[0126] However, this disclosure is not limited to this. The top surface of the support structure 76 can also be higher than the light-emitting surfaces of the two adjacent display screens 100. That is, the distance between the top surface of the support structure 76 and the light-emitting surface of the display device 200 is less than the distance between the light-emitting surfaces of the display screen 100 and the light-emitting surfaces of the display device 200. This allows the light-transmitting part 77 to be spaced apart from the corresponding display screen 100, reducing the friction between the filter part and the adjacent display screen 100 when relative displacement occurs between the adjacent display screens 100, and reducing the risk of damage to the filter part and the display screen 100.

[0127] In this disclosure, the support structure 76 can be spaced apart from the adjacent display screen 100 to reserve a certain amount of space for movement between the support structure 76 and the adjacent display screen 100, thereby improving the problem of collision and compression between the support structure 76 and the display screen 100. However, it is not limited to this; the support structure 76 can also abut against the adjacent display screen 100, and the specific configuration can be determined according to the actual situation.

[0128] For example, the distance between the support structure 76 and the adjacent display screen 100 can be 2 μm, but it is not limited to this. The distance between the support structure 76 and the adjacent display screen 100 can also be other values ​​other than 2 μm, depending on the actual situation.

[0129] In some embodiments, the display device 200 may include a light-transmitting layer disposed on the light-emitting surface of the display screen 100 and the light-emitting side of the reflective structure. The light-transmitting layer may include a light-transmitting portion 77 and a light-filtering portion, the light-transmitting portion 77 being connected to the light-filtering portion, and the light-transmitting portion 77 being located on the light-emitting surface of the display screen 100, and the light-transmitting portion 77 having light transmittance.

[0130] The light-transmitting layer can cover the light-emitting surface of the display device 200. The light-transmitting layer may include multiple light-transmitting portions 77, each corresponding to a different display screen 100, with a filter portion located between adjacent light-transmitting portions 77. Light from the display screen 100 can be emitted to the light-emitting surface of the display device 200 through the light-transmitting portions 77.

[0131] For example, the light-transmitting portion 77 in this disclosure may be rigid glass or a rigid resin substrate.

[0132] By providing the light-transmitting portion 77, this disclosure can improve the overall structural strength of the light-transmitting layer and reduce the risk of deformation of the light-transmitting layer. When the side of the light-transmitting layer facing away from the light-emitting surface of the display device 200 comes into contact with the light-emitting surface of the display screen 100, the light-transmitting portion 77 can increase the contact area between the light-transmitting layer and the display screen 100, thereby improving the installation stability between the light-transmitting layer and the display screen 100.

[0133] Furthermore, when the display device 200 includes both a support structure 76 and a light-transmitting portion 77, both the support structure 76 and the light-transmitting portion 77 can be made of light-transmitting materials. When the support structure 76 and the light-transmitting portion 77 are made of the same material, they can be arranged in the same layer. That is, light-transmitting materials can be simultaneously arranged in the seam area and on the light-emitting surface of the display screen 100, so that the support structure 76 and the light-transmitting portion 77 can be formed simultaneously. This simplifies the overall manufacturing process of the display device 200 and improves the manufacturing efficiency of the display device 200.

[0134] In some embodiments, the range of the angle θ2 between the first reflective surface 74 and the light-emitting surface of the display screen 100, and the range of the angle θ3 between the second reflective surface 75 and the light-emitting surface of the display screen 100, can both be 45°~75°.

[0135] For example, the angle θ2 between the first reflective surface 74 and the light-emitting surface of the display device 200, and the angle θ3 between the second reflective surface 75 and the light-emitting surface of the display device 200 can both be 45°, 50°, 55°, 60°, 65°, 70°, 75°, etc., and can be set according to the actual situation.

[0136] The first reflective surface 74 and the second reflective surface 75 can be arranged in a mirror-symmetric manner about the center of the seam area. In this case, the orthographic projection of the center of the light-shielding area 73 onto the seam area can coincide with the center of the seam area. However, this is not a limitation. The first reflective surface 74 and the second reflective surface 75 can also be arranged in a non-mirror-symmetric manner about the center of the seam area. The specific arrangement can be determined according to the actual situation.

[0137] like Figures 9 to 10 As shown, in some embodiments, both the first reflective surface 74 and the second reflective surface 75 can be parallel to the corresponding adjacent reflective layer 14.

[0138] When the display light source is perpendicular to the light-emitting surface of the display device 200, the light from the display light source shines on the reflective layer 14 and is reflected by the reflective layer 14 onto the corresponding first reflective surface 74 or second reflective surface 75. The light reflected by the first reflective surface 74 and the second reflective surface 75 can be collimated and emitted in a direction perpendicular to the light-emitting surface of the display device 200, thereby reducing light loss.

[0139] However, it is not limited to this. The first reflective surface 74 and the corresponding adjacent reflective layer 14, as well as the second reflective surface 75 and the corresponding adjacent reflective layer 14, can also intersect. The specific settings can be determined according to the actual situation.

[0140] It should be noted that the light-emitting surface of the display screen in this disclosure can be parallel to the light-emitting surface of the display device.
