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] OLED displays offer advantages such as high saturation and high contrast, making them suitable for outdoor displays in strong sunlight. However, due to the complexity of the manufacturing process, a single OLED display cannot be made in a large size. Therefore, multiple display panels are spliced ​​together to achieve a large-screen display. When multiple display panels are spliced ​​together, seams are created between adjacent panels, affecting the visual effect. Summary of the Invention

[0003] The purpose of this disclosure is to provide a display screen and display device that can reflect some light to the splicing surface of the display screen through a reflective structure, thereby improving the problem of black borders appearing at the seams of multiple spliced ​​display screens.

[0004] This disclosure provides a display screen having a display surface and a splicing surface located on the side of the display surface, the display screen comprising:

[0005] Substrate;

[0006] An organic light-emitting functional layer is formed on the substrate, which includes multiple organic light-emitting structures arranged in an array, and the organic light-emitting structure adjacent to the splicing surface is defined as an edge light-emitting structure;

[0007] A reflective structure is disposed on the side of the edge light-emitting structure away from the substrate. The reflective structure includes at least an inclined reflective portion that covers the edge portion of the edge light-emitting structure near the splicing surface, and the inclined reflective portion is inclined away from the edge light-emitting structure in the direction close to the splicing surface.

[0008] In this process, some of the light emitted by the edge-emitting structure is directed toward the display surface, while some of the light is reflected by the tilted reflector to the splicing surface.

[0009] In one exemplary embodiment of this disclosure, the tilted reflective portion includes a first reflective layer and a second reflective layer, wherein the second reflective layer is located on the side of the first reflective layer away from the edge light-emitting structure and is spaced apart from the first reflective layer;

[0010] The second reflective layer is positioned so that the end furthest from the splicing surface protrudes relative to the first reflective layer;

[0011] In the direction close to the splicing surface, both the first reflective layer and the second reflective layer are inclined away from the edge light-emitting structure.

[0012] In one exemplary embodiment of this disclosure, the tilted reflective portion further includes a third reflective layer located on the side of the first reflective layer near the edge-emitting structure. The third reflective layer covers the edge portion of the edge-emitting structure near the splicing surface, and in the direction near the splicing surface, the third reflective layer is tilted away from the edge-emitting structure to be configured to reflect a portion of the light emitted by the edge-emitting structure to the splicing surface.

[0013] In one exemplary embodiment of this disclosure, the second reflective layer has a plurality of light-transmitting holes, which are disposed through the second reflective layer.

[0014] In one exemplary embodiment of this disclosure, the reflective structure includes a fourth reflective layer, which is located on the side of the first reflective layer near the splicing surface and is in contact with the first reflective layer; the angle between the fourth reflective layer and the display surface is smaller than the angle between the first reflective layer and the display surface.

[0015] In one exemplary embodiment of this disclosure, the tilt angle of the second reflective layer is greater than the tilt angle of the first reflective layer.

[0016] In one exemplary embodiment of this disclosure, the display screen includes:

[0017] A first organic encapsulation layer covers the substrate and the organic light-emitting functional layer, with one end of the first organic encapsulation layer near the splicing surface located between the first reflective layer and the edge-emitting structure.

[0018] A second organic encapsulation layer covers the first organic encapsulation layer and the first reflective layer, with one end of the second organic encapsulation layer near the splicing surface located between the first reflective layer and the second reflective layer;

[0019] A third organic encapsulation layer covers the second organic encapsulation layer and the second reflective layer.

[0020] This disclosure also provides a display device, including a reflective structure and a plurality of displays as described above, wherein the plurality of displays are spliced ​​together by the splicing surface, and there is a splicing seam area between adjacent displays. The reflective structure is located in the splicing seam area, and the reflective structure is configured to guide light emitted from the splicing surface of two adjacent displays to the display surface of the display device.

[0021] In one exemplary embodiment of this disclosure, the display screen includes a color resist layer, the color resist layer includes a plurality of color resist blocks, and the color resist blocks correspond one-to-one with the organic light-emitting structure; the color resist block adjacent to the splicing surface is defined as a splicing color resist block;

[0022] The display device includes a light filter, which is disposed on the light-emitting side of the reflective structure;

[0023] On the display 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.

[0024] 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.

[0025] 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;

[0026] 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;

[0027] The reflective structure includes a first reflective surface facing the first spliced ​​color resist block and a second reflective surface facing the second spliced ​​color resist block.

[0028] The technical solutions provided in this disclosure have at least the following advantages:

[0029] This embodiment of the present disclosure provides a reflective structure on the side of the edge-emitting structure away from the substrate. While ensuring that some of the light emitted by the edge-emitting structure reaches the display surface of the display screen to achieve image display, the tilted reflective part in the reflective structure can also reflect some of the light emitted by the edge-emitting structure to the splicing surface of the display screen. When multiple displays are spliced, the brightness at the splicing seam between adjacent displays can be increased, and the difference between the brightness at the splicing seam and the brightness of adjacent displays can be reduced. This can improve the problem of black borders appearing at the splicing seam of multiple spliced ​​displays and improve the display effect of the entire large display screen formed after multiple displays are spliced.

[0030] Other features and advantages of this disclosure will become apparent from the following detailed description, or may be learned in part from practice of this disclosure.

[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] OLED displays offer advantages such as high saturation and high contrast, making them suitable for outdoor displays in strong sunlight. However, due to the complexity of the manufacturing process, a single OLED display cannot be made in a large size. Therefore, multiple display panels are spliced ​​together to achieve a large-screen display. When multiple display panels are spliced ​​together, seams are created between adjacent panels, affecting the visual effect.

[0049] In addition, splicing screens will generally be relatively misaligned during use. The degree of misalignment may vary depending on the location of the splicing screen. The weakening and compensation of the splicing seams that were originally used (e.g., setting OLED display panels in the seam between two adjacent displays) will change after the misalignment.

[0050] like Figure 1-2 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.).

[0051] Since there are seams around the display screen 100, the display effect at the seam will change significantly when the seam distance changes. Different seams on the entire display device 200 will have different display effects, resulting in serious unevenness in the overall display.

[0052] To solve the above technical problems, such as Figure 3-5 As shown, this disclosure provides a display screen 100, which has a display surface and a splicing surface located on the side of the display surface. The display screen 100 may include: a substrate 1, an organic light-emitting functional layer, and a reflective structure 5. The organic light-emitting functional layer is formed on the substrate 1, and may include a plurality of organic light-emitting structures arranged in an array. The organic light-emitting structure adjacent to the splicing surface is defined as an edge light-emitting structure 201. The reflective structure 5 is disposed on the side of the edge light-emitting structure 201 facing away from the substrate 1. The reflective structure 5 includes at least an inclined reflective portion, which covers the edge portion of the edge light-emitting structure 201 near the splicing surface, and in the direction near the splicing surface, the inclined reflective portion is inclined away from the edge light-emitting structure 201.

[0053] Part of the light emitted by the edge-emitting structure 201 can also be directed toward the display surface to achieve the display of the image on the display screen 100. Part of the light emitted by the edge-emitting structure 201 can be reflected by the tilted reflector to the splicing surface to enhance the intensity of the emitted light from the splicing surface of the display screen 100. When multiple display screens 100 are spliced ​​together, the brightness at the seam between adjacent display screens 100 can be increased, and the difference between the brightness at the seam and the brightness of adjacent display screens 100 can be reduced. This can improve the problem of black borders appearing at the seams of multiple spliced ​​display screens 100, and improve the display effect of the entire large display screen formed after multiple display screens 100 are spliced ​​together.

[0054] It should be noted that the display screen 100 in this disclosure may include one or more splicing surfaces.

[0055] For example, when another display screen 100 is provided on both sides of a display screen 100, the two sides of the display screen 100 closest to the other two display screens 100 are splicing surfaces, that is, the two sides of the display screen 100 are splicing surfaces.

[0056] In this disclosure, when the display screen 100 includes multiple splicing surfaces, "close to splicing surface" means close to the adjacent splicing surface, and "away from (or away from) splicing surface" means away from (or away from) the adjacent splicing surface.

[0057] For example, "the edge portion of the edge-emitting structure 201 near the splicing surface" means the edge portion of the edge-emitting structure 201 near the adjacent splicing surface.

[0058] In some embodiments, the tilted reflective portion may include a first reflective layer 51 and a second reflective layer 52. The second reflective layer 52 is located on the side of the first reflective layer 51 away from the edge-emitting structure 201 and is spaced apart from the first reflective layer 51. The end of the second reflective layer 52 away from the splicing surface protrudes relative to the first reflective layer 51. The second reflective layer 52 can cover the edge portion of the edge-emitting structure 201 near the splicing surface to reflect the light emitted by the edge-emitting structure 201. In the direction near the splicing surface, both the first reflective layer 51 and the second reflective layer 52 are tilted away from the edge-emitting structure 201.

[0059] The second reflective layer 52 is configured to reflect part of the light emitted by the edge light-emitting structure 201 onto the first reflective layer 51. The light reflected from the second reflective layer 52 onto the first reflective layer 51 can be reflected again by the first reflective layer 51 until the light can be directed toward the display surface or the splicing surface.

[0060] That is, after some of the light emitted from the edge-emitting structure 201 shines on the second reflective layer 52, it can be reflected multiple times between the second reflective layer 52 and the first reflective layer 51 until the light can shine on the display surface of the display screen 100 or on the splicing surface.

[0061] It should be noted that, since the edge area of ​​the edge-emitting structure 201 near the splicing surface is covered by the reflective structure 5, the probability of the light emitted by the edge-emitting structure 201 hitting the edge area of ​​the display surface of the display screen 100 near the splicing surface is greatly reduced, which in turn causes the display brightness of the edge area of ​​the display surface of the display screen 100 near the splicing surface to be much lower than the display brightness of other areas of the display surface.

[0062] This disclosure, by setting a first reflective layer 51 and a second reflective layer 52, allows some of the light reflected by the first reflective layer 51 and the second reflective layer 52 to be emitted onto the display surface of the display screen 100. This increases the display brightness of the edge area of ​​the display surface of the display screen 100 near the splicing surface, thereby reducing the difference in display brightness between the edge area of ​​the display surface of the display screen 100 near the splicing surface and other areas of the display surface of the display screen 100, improving the uniformity of the overall display brightness of the display screen 100, and enhancing the display effect.

[0063] In some embodiments, the tilt angle θ1 of the first reflective layer 51 is different from the tilt angle θ2 of the second reflective layer 52. That is, the angle between the first reflective layer 51 and the display surface of the display screen 100 and the angle between the second reflective layer 52 and the display surface of the display screen 100 are different, so as to achieve light diffusion and reflection, thereby improving the problem that light is concentrated at one angle, resulting in a large difference in display brightness at that angle compared to other angles.

[0064] Specifically, the tilt angle θ2 of the second reflective layer 52 can be greater than the tilt angle θ1 of the first reflective layer 51 to increase the light emission angle, so that the light can be evenly emitted to the splicing surface and the edge area of ​​the display surface of the display screen 100 near the splicing surface. This improves the brightness difference between the splicing seam and the edge area of ​​the display surface of the display screen 100 when multiple display screens 100 are spliced, and enhances the display effect of the entire large display screen formed after multiple display screens 100 are spliced.

[0065] The tilt angle θ2 of the second reflective layer 52 can be in the range of 60° to 85°, and the tilt angle θ1 of the first reflective layer 51 can be in the range of 45° to 60°, so that the light between the first reflective layer 51 and the second reflective layer 52 can be diffused and reflected to the splicing surface and the display surface of the display screen 100.

[0066] For example, the tilt angle θ2 of the second reflective layer 52 can be 60°, 65°, 70°, 75°, 80°, 85°, etc., depending on the actual situation.

[0067] The tilt angle θ1 of the first reflective layer 51 can be 45°, 50°, 55°, 60°, etc., and can be determined according to the actual situation.

[0068] In some embodiments, the second reflective layer 52 has a plurality of light-transmitting holes 521, which are disposed through the second reflective layer 52.

[0069] Part of the light emitted by the edge-emitting structure 201 and part of the light reflected from the first reflective layer 51 onto the second reflective layer 52 can be emitted through the light-transmitting hole 521 onto the display surface of the display screen 100. This can increase the display brightness of the area corresponding to the reflective structure 5 on the display surface of the display screen 100, reduce the difference in display brightness between the area corresponding to the reflective structure 5 and other areas on the display surface of the display screen 100, improve the uniformity of the overall display brightness of the display screen 100, and enhance the display effect.

[0070] Furthermore, the size of the light-transmitting hole 521 can be no less than 1μm, so that light can pass through the light-transmitting hole 521 and be emitted to the display surface of the display screen 100.

[0071] The ratio between the area of ​​all the light-transmitting holes 521 in the second reflective layer 52 and the area of ​​the region in the second reflective layer 52 used for reflecting light can be 1:2. This ensures that enough light passes through the second reflective layer 52 and is reflected out from the splicing surface, while also ensuring that enough light is emitted to the display surface of the display screen 100.

[0072] The multiple light-transmitting holes 521 in the second reflective layer 52 can be arranged in an array to improve the uniformity of light emitted from the light-transmitting holes 521 onto the display surface of the display screen 100.

[0073] In some embodiments, the tilted reflective portion further includes a third reflective layer 53, which is located on the side of the first reflective layer 51 near the edge light-emitting structure 201. The third reflective layer 53 covers the edge portion of the edge light-emitting structure 201 near the splicing surface, and in the direction near the splicing surface, the third reflective layer 53 is tilted away from the edge light-emitting structure 201.

[0074] The light emitted by the edge-emitting structure 201 can illuminate the third reflective layer 53. The third reflective layer 53 is configured to reflect part of the light emitted by the edge-emitting structure 201 back to the splicing surface, thereby increasing the brightness of the light emitted from the splicing surface. When multiple displays 100 are spliced ​​together, the brightness at the seam between the multiple displays 100 can be increased, reducing the difference between the brightness at the seam and the display brightness of adjacent displays 100, thus improving the display effect of the entire large display screen formed after the multiple displays 100 are spliced ​​together.

[0075] It should be noted that when the tilted reflective part includes the third reflective layer 53, the end of the second reflective layer 52 away from the splicing surface not only protrudes relative to the first reflective layer 51, but also protrudes relative to the third reflective layer 53, so that the light emitted by the edge light-emitting structure 201 can illuminate the second reflective layer 52.

[0076] For example, the end of the first reflective layer 51 away from the splicing surface can be flush with the end of the third reflective layer 53 away from the splicing surface.

[0077] Furthermore, the orthographic projection of the first reflective layer 51 on the substrate 1 can be made to coincide with the orthographic projection of the third reflective layer 53 on the substrate 1.

[0078] It should be noted that the first reflective layer 51 and the third reflective layer 53 can be integrally formed to simplify the manufacturing process.

[0079] However, this is not the only option; the fabrication processes of the first reflective layer 51 and the third reflective layer 53 can also be independent of each other. In this case, the first reflective layer 51 and the third reflective layer 53 can be stacked and connected to each other in a direction away from the substrate 1.

[0080] In some embodiments, the angle between the third reflective layer 53 and the display surface of the display screen 100 (i.e., the tilt angle θ3 of the third reflective layer 53) can be in the range of 45° to 60°. This ensures that the projected area of ​​the third reflective layer 53 on the edge light-emitting structure 201 is sufficient to allow more light emitted from the edge light-emitting structure 201 to illuminate the third reflective layer 53, while also allowing the light reflected by the third reflective layer 53 to illuminate the splicing surface as much as possible, thereby improving the brightness of the light emitted by the display screen 100 through the splicing surface.

[0081] For example, the tilt angle θ3 of the third reflective layer 53 can be 45°, 50°, 55°, 60°, etc., depending on the actual situation.

[0082] In some embodiments, the reflective structure 5 may include a fourth reflective layer 54, which is located on the side of the first reflective layer 51 near the splicing surface and is in contact with the first reflective layer 51. The reflected light from the second reflective layer 52 may be reflected onto one of the first reflective layer 51 and the fourth reflective layer 54 until the light passes through the first reflective layer 51 or the fourth reflective layer 54 and exits onto the splicing surface or the display surface of the display screen 100.

[0083] By providing a fourth reflective layer 54, this disclosure can reflect more reflected light from the second reflective layer 52, further increasing the light output brightness of the display surface and splicing surface of the display screen 100, improving the utilization rate of the light emitted by the edge light-emitting structure 201, and thus reducing energy consumption.

[0084] For example, the end of the fourth reflective layer 54 furthest from the first reflective layer 51 can be flush with the splicing surface, so that more reflected light from the second reflective layer 52 can be reflected by the fourth reflective layer 54 and emitted onto the display surface or splicing surface of the display screen 100, thereby improving the utilization rate of the light emitted by the edge-emitting structure 201. However, this is not the only possibility; the end of the fourth reflective layer 54 furthest from the first reflective layer 51 can also be spaced apart from the splicing surface, depending on the actual situation.

[0085] In this disclosure, the angle between the fourth reflective layer 54 and the display surface can be smaller than the tilt angle θ1 of the first reflective layer. While reflecting the light reflected by the second reflective layer 52, the fourth reflective layer 54 also increases the light emission angle, achieving light diffusion. The light reflected by the fourth reflective layer 54 can be evenly emitted to the splicing surface and the edge area of ​​the display surface of the display screen 100 near the splicing surface. This can improve the brightness difference between the seam between adjacent display screens 100 and the edge area of ​​the display surface of the display screen 100 when multiple display screens 100 are spliced, thereby improving the display effect of the entire large display screen formed after splicing multiple display screens 100.

[0086] In some embodiments, the reflective structure 5 may include a light-shielding layer 55, with a first reflective layer 51 and a third reflective layer 53 disposed on opposite sides of the light-shielding layer 55, and a fourth reflective layer 54 located on the same side of the light-shielding layer 55 as the first reflective layer 51.

[0087] The light-shielding layer 55 has light-shielding properties to improve the problems of light transmission between the first reflective layer 51 and the third reflective layer 53, and light from the side of the light-shielding layer 55 away from the fourth reflective layer 54 being directly transmitted to the fourth reflective layer 54. This ensures that light on each reflective layer can be reflected at a preset angle, thereby improving the reliability of the light emission angle and the reliability of the displayed image.

[0088] In some embodiments, organic light-emitting structures other than the edge-emitting structure 201 can be defined as normal light-emitting structures 202. In the direction perpendicular to the splicing surface, the size of the edge-emitting structure 201 can be larger than the size of the normal light-emitting structure 202, so that the brightness of the light emitted by the edge-emitting structure 201 is greater than the brightness of the light emitted by the normal light-emitting structure 202. While reflecting part of the light emitted by the edge-emitting structure 201 to the splicing surface through the tilted reflector, it can also be ensured that the edge-emitting structure 201 has enough light to be introduced into the display surface of the display screen 100 for display.

[0089] It should be noted that the "size of edge-emitting structure 201" and "size of normal-emitting structure 202" mentioned above refer to the length of the corresponding structure in the direction perpendicular to the splicing surface.

[0090] It should also be noted that the display screen 100 has multiple pixels, and there is a one-to-one correspondence between the pixels and the organic light-emitting structures. Pixels can include edge pixels and normal pixels. Edge pixels correspond to the edge light-emitting structure 201, and normal pixels correspond to the normal light-emitting structure 202. When the size of the edge light-emitting structure 201 is larger than the size of the normal light-emitting structure 202, the size of the edge pixel is also larger than the size of the normal pixel.

[0091] For example, in the direction perpendicular to the splicing surface, the ratio of the size of the normal light-emitting structure 202 to the size of the edge light-emitting structure 201 can be in the range of 1:2 to 1:3. This ensures that the edge light-emitting structure 201 has enough light to be introduced to both the display surface and the splicing surface of the display screen 100, thereby enabling the display surface of the display screen 100 to display a normal image while also ensuring that enough light is emitted through the splicing surface. Similarly, the ratio of the size of the normal pixel to the size of the edge pixel can also be in the range of 1:2 to 1:3.

[0092] However, it is not limited to this. The ratio of the size of the normal light-emitting structure 202 to the size of the edge light-emitting structure 201 can also be any value other than 1:2 to 1:3. Similarly, the ratio of the size of the normal pixel to the size of the edge pixel can also be any value other than 1:2 to 1:3. The specific value can be set according to the actual situation.

[0093] like Figure 6 As shown, the area with reflective structure 5 in the edge pixels is defined as the reflective area, and the area without reflective structure 5 in the edge pixels is defined as the light-transmitting area. On the display 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.

[0094] 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 pixel can be 1:1 to ensure that the edge pixels can achieve a normal image display with at least the same size as the normal pixels in the light-transmitting area. Within the allowable error range, the ratio of the size of the light-transmitting area to the size of the normal pixel can be appropriately adjusted based on the 1:1 ratio.

[0095] It should be noted that the overall size of the display screen 100 remains unchanged after the pixel size is adjusted in this disclosure.

[0096] For example, when the display screen 100 in the related technology includes multiple pixel units, and a pixel unit near the splicing surface includes a first pixel, a second pixel, and a third pixel arranged sequentially in a direction perpendicular to the splicing surface, and the length of the three types of pixels in the direction perpendicular to the splicing surface is P, in this disclosure, the lengths of the three types of pixels in the pixel unit near the splicing surface in the direction perpendicular to the splicing surface can be adjusted to (3 / 5)×P, (3 / 5)×P, and (9 / 5)×P respectively, so that the overall length of the pixel unit in the direction perpendicular to the splicing surface remains unchanged, thereby keeping the overall size of the display screen 100 unchanged.

[0097] In some embodiments, the display screen 100 may include a first organic encapsulation layer 41, a second organic encapsulation layer 42, and a third organic encapsulation layer 43.

[0098] The first organic encapsulation layer 41, the second organic encapsulation layer 42, and the third organic encapsulation layer 43 are transparent. All three can be made of flexible, elastic, and bendable materials such as acrylic resin, polyimide, and epoxy resin to isolate the organic light-emitting structure from external moisture and to absorb and release stress, thereby improving the bending resistance of the display screen 100.

[0099] Specifically, the first organic encapsulation layer 41 can cover the substrate 1 and the organic light-emitting functional layer, and its end near the splicing surface is located between the first reflective layer 51 and the edge-emitting structure 201. The first organic encapsulation layer 41 can provide support for the fabrication of the first reflective layer 51, the third reflective layer 53, and the fourth reflective layer 54. The second organic encapsulation layer 42 can cover the first organic encapsulation layer 41 and the first reflective layer 51, and its end near the splicing surface is located between the first reflective layer 51 and the second reflective layer 52. The second organic encapsulation layer 42 can provide support for the fabrication of the second reflective layer 52. The third organic encapsulation layer 43 can cover the second organic encapsulation layer 42 and the second reflective layer 52.

[0100] When the reflective structure 5 includes a fourth reflective layer 54, the second organic encapsulation layer 42 can also cover the fourth reflective layer 54.

[0101] In this disclosure, the first organic encapsulation layer 41, the second organic encapsulation layer 42, and the third organic encapsulation layer 43 can be made of the same material to reduce the manufacturing difficulty and cost of the display screen 100. However, this is not a limitation; the first organic encapsulation layer 41, the second organic encapsulation layer 42, and the third organic encapsulation layer 43 can also be made of different materials, depending on the actual situation.

[0102] In addition, the display screen 100 may also include an inorganic encapsulation layer 44, which covers the side of the third organic encapsulation layer 43 away from the second organic encapsulation layer 42, in order to strengthen the barrier against external moisture and reduce the risk of external moisture intruding into the organic light-emitting structure, thereby extending the service life of the display screen 100.

[0103] In some embodiments, the substrate 1 may include thin-film transistors configured to control the driving of pixels, thereby controlling the display screen 100 to display an image.

[0104] Furthermore, the substrate 1 may include multiple thin-film transistors, which may correspond one-to-one with the pixels of the display screen 100 to achieve partition control of the display screen 100 displaying images.

[0105] In some embodiments, the organic light-emitting structure may include an anode 21, an organic light-emitting layer 22, and a cathode 23, which are arranged sequentially in a direction away from the substrate 1. Power can be supplied by a thin-film transistor to make the organic light-emitting structure emit light.

[0106] In this disclosure, the organic light-emitting structure can emit white light, but it is not limited to this. The organic light-emitting structure can also emit light of colors other than white, and the specific settings can be made according to the actual situation.

[0107] In some embodiments, the display screen 100 may include a PDL (suspended structure base) 31, which is disposed on the substrate 1 and surrounds each pixel of the display screen 100.

[0108] PDL31 can form pixel boundaries. When the anode 21, organic light-emitting layer 22, and cathode 23 are deposited in each pixel region, PDL31 is located between two adjacent pixels to block the crosstalk between adjacent organic light-emitting structures, improve the problem of crosstalk between light-emitting layers / electrodes between different pixels (e.g., short circuit of anode 21), and improve the resolution of display screen 100. When display screen 100 is a color display, PDL31 separates different pixels, which can also help to realize the color of display screen 100.

[0109] In some embodiments, the display screen 100 may further include isolation pillars 32, which are located on the side of the PDL 31 away from the substrate 1 and are disposed around each pixel.

[0110] Generally, the isolation pillars 32 are distributed in the non-light-emitting areas (pixel non-aperture areas) of the display 100 to reduce occlusion of the pixel aperture areas and ensure the pixel aperture ratio of the display 100. The isolation pillars 32 are supported between the PDL31 and the organic encapsulation layer to resist external pressure / bending force, strengthen the protection of the organic light-emitting structure, and improve the overall structural reliability of the display 100.

[0111] In some embodiments, the display screen 100 may further include a color filter structure (COE structure, also known as a color filter structure fabricated on the package), the color filter structure being located on the side of the inorganic encapsulation layer 44 away from the substrate 1, in order to filter the light emitted by the organic light-emitting structure and realize the color display of the display screen 100.

[0112] For example, the COE structure may include a color resist layer 62, which may include multiple color resist blocks, each corresponding to an organic light-emitting structure.

[0113] Color filter blocks can include red, green, and blue color filter blocks to filter red, green, and blue light respectively.

[0114] In the direction perpendicular to the splicing surface, the size of the color block can be proportional to the size of the corresponding pixel.

[0115] For example, the color resist block adjacent to the splicing surface is defined as splicing color resist block 621, and the other color resist blocks are defined as normal color resist blocks 622. In the direction perpendicular to the splicing surface, when the size of the edge pixel is larger than the size of the normal pixel, the size of splicing color resist block 621 is also larger than the size of normal color resist block 622.

[0116] 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 621 with a size larger than the normal color resist block 622.

[0117] Furthermore, the color resist layer 62 may also include a light-blocking block 623 located between two adjacent color resist blocks and having light-absorbing properties, configured to improve the color mixing problem between two adjacent pixels, thereby improving the display contrast of the display screen 100.

[0118] The orthographic projection of the light-shielding block 623 on the substrate 1 can coincide with the orthographic projection of the isolation pillar 32 on the substrate 1.

[0119] In some embodiments, the COE structure may include a polyimide film 61 (PI Film), which is located on the side of the color resist layer 62 near the substrate 1.

[0120] Polyimide film 61 is a high-temperature resistant and highly flexible polymer film that can serve as a flexible, flat substrate to provide high-temperature resistant and bendable support for color resist layer 62. Simultaneously, polyimide film 61 can also achieve insulation isolation between the COE structure and driving structures such as thin-film transistors, improving the problem of electrical interference.

[0121] In some embodiments, the COE structure may include a planarization layer 63 (OC) covering the side of the color resist layer 62 away from the substrate 1, so as to reduce or eliminate the step difference formed on the side of the color resist layer 62 away from the substrate 1, and provide a smooth interface for the subsequent fabrication of the functional film layer 64.

[0122] In some embodiments, the COE structure may include a functional film 64, which may include one or more of a polarizer, an anti-reflective film, a touch-sensitive layer, and an anti-fingerprint film, to improve the display effect of the display screen 100.

[0123] like Figure 7 As shown in this disclosure, the fabrication process of the display screen 100 may include: step (1) forming a first organic encapsulation layer 41 on the side of the organic light-emitting structure facing away from the substrate 1 and on the side of the substrate 1 close to the organic light-emitting structure. The thickness of the first organic encapsulation layer 41 may range from 5 μm to 10 μm. A first inclined surface 411 is provided on the edge region of the side of the first organic encapsulation layer 41 facing away from the substrate 1 (the edge region refers to the region close to the splicing surface). In the direction close to the splicing surface, the first inclined surface 411 is inclined away from the organic light-emitting structure. The angle between the first inclined surface 411 and the display surface of the display screen 100 may range from 45° to 60°. The orthographic projection of the first inclined surface 411 on the edge light-emitting structure 201 can cover the edge region of the edge light-emitting structure 201 close to the splicing surface. In the side of the first organic encapsulation layer 41 facing away from the substrate 1, except for the first inclined surface 411, the remaining region may be parallel to the display surface of the display screen 100.

[0124] Step (2): A third reflective layer 53 and a first reflective layer 51 are disposed on the first inclined surface 411. Furthermore, a fourth reflective layer 54 may be disposed on the side of the first reflective layer 51 near the splicing surface. The size of the fourth reflective layer 54 in the direction perpendicular to the splicing surface can be 1µm to 2µm.

[0125] Step (3): A second organic encapsulation layer 42 is disposed on the side of the first organic encapsulation layer 41, the first reflective layer 51, and the fourth reflective layer 54 facing away from the substrate 1. The thickness of the second organic encapsulation layer 42 can range from 10µm to 15µm. A second inclined surface 421 is disposed on the edge region of the side of the second organic encapsulation layer 42 facing away from the substrate 1 (i.e., the region near the splicing surface). The second inclined surface 421 is inclined away from the substrate 1 in the direction near the splicing surface. The angle between the second inclined surface 421 and the display surface of the display screen 100 can range from 60° to 85°. The end of the second inclined surface 421 away from the splicing surface can protrude relative to the first inclined surface 411, and the protrusion distance can range from 0.5µm to 1µm. The orthogonal projection of the second inclined surface 421 onto the edge light-emitting structure 201 can cover the edge region of the edge light-emitting structure 201 near the splicing surface. In the side of the second organic encapsulation layer 42 facing away from the substrate 1, except for the second inclined surface 421, the remaining region can be parallel to the display surface of the display screen 100.

[0126] Step (4): A second reflective layer 52 is disposed on the second inclined surface 421. The second reflective layer 52 includes a plurality of light-transmitting holes 521 arranged at uniform intervals.

[0127] Step (5): A third organic encapsulation layer 43 is provided on the side of the second organic encapsulation layer 42 and the second reflective layer 52 away from the substrate 1. The thickness of the third organic encapsulation layer 43 can be in the range of 2um to 5um.

[0128] Step (6): An inorganic encapsulation layer 44 is disposed on the side of the third organic encapsulation layer 43 away from the organic light-emitting structure. The thickness of the inorganic encapsulation layer 44 can be in the range of 0.3um to 0.6um.

[0129] Step (7): A COE structure is formed on the side of the inorganic encapsulation layer 44 facing away from the substrate 1. The color resist block in the COE structure has high transmittance for red, green and blue light (up to 60%), while having greater absorption for other wavelengths. Since ambient light generally includes the entire visible light band or a broad spectrum, the color resist layer 62 can filter out most of the ambient light bands, so the ambient light has little impact on the intensity of the emitted light from the display surface of the display screen 100.

[0130] like Figure 8 As 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 by splicing surfaces, and there is a seam area between adjacent displays 100. The reflective structure is located in the seam area and is configured to guide light emitted from the splicing surfaces of two adjacent displays 100 to the display surface of the display device 200.

[0131] Compared to Figure 9 Regarding the display device 200 in the related art, the display device 200 of this disclosure can improve the display brightness of the display surface of the display device 200 in the splicing area through the reflective structure 5 in the display screen 100, thereby improving the black border problem that appears in the splicing area of ​​the display device 200.

[0132] It should be noted that the display surface of the display screen 100 and the display surface of the display device 200 can be parallel to each other.

[0133] In some embodiments, the display device 200 may include a light filter, which is disposed on the light-emitting side of the reflective structure (i.e. the side of the reflective structure close to the display surface of the display device 200) and is configured to filter light and allow light of a specific color to pass through.

[0134] The orthographic projection of the filter on the display surface of the display device 200 can completely cover the orthographic projection of the seam area on the display surface of the display device 200, thereby enabling the display surface of the display device 200 to display a specific color image at the corresponding position of the seam area.

[0135] Furthermore, the orthographic projection of the filter on the display surface of the display device 200 can also cover the orthographic projection of the edge portion of the adjacent splicing color resist block 621 on the display 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 display surface of the display device 200 can always completely block the orthographic projection of the corresponding splicing area on the display 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 display surface of the display device 200.

[0136] The display device 200 may include multiple light filters, each of which corresponds to a seam area, thereby allowing adjustment of the display effect of each seam area on the display surface of the display device 200.

[0137] In some embodiments, the filter section may include a first filter area 71 and a second filter area 72, and the arrangement direction of the first filter area 71 and the second filter area 72 is the same as the arrangement direction of two adjacent displays 100.

[0138] The splicing color resist block 621 in the display screen 100 adjacent to the first filter area 71 is defined as the first splicing color resist block 624, and the splicing color resist block 621 in the display screen 100 adjacent to the second filter area 72 is defined as the second splicing color resist block 625.

[0139] In this design, the first filter area 71 has the same color as the first splicing color block 624, and the second filter area 72 has the same color as the second splicing color block 625. This allows the light emitted from the display surface of the display device 200 in the corresponding area of ​​the splicing seam to be the same as the colors of the adjacent first splicing color block 624 and the adjacent second splicing color block 625, thus 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.

[0140] In the filter section, the first filter area 71 can cover the edge portion of the first splicing color resist block 624, and the second filter area 72 can cover the edge portion of the second splicing color resist block 625.

[0141] When relative displacement occurs between adjacent displays 100, causing a change in the size of the seam area, the orthographic projection of the first filter area 71 on the display surface of the display device 200 always overlaps with the orthographic projection of the first splicing color block 624 on the display surface of the display device 200, and the orthographic projection of the second filter area 72 on the display surface of the display device 200 always overlaps with the orthographic projection of the second splicing color block 625 on the display surface of the display device 200. Thus, a natural color transition between the seam area and the adjacent displays 100 can be achieved through the first filter area 71 and the second filter area 72, improving the problem of visual discontinuity between the display device 200 and the display 100 in the seam area, and compensating for the difference in display effect caused by changes in the size of the seam area.

[0142] In some embodiments, the light filter may further include a light-shielding area 73 located between the first light filter area 71 and the second light filter area 72, and the light-shielding area 73 is configured to block light. When the colors of two adjacent color resist blocks 621 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 filter area 71 and the light from the second light filter area 72, thereby improving the image purity and contrast of the display surface of the display device 200.

[0143] 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.

[0144] The length of the seam area in the display device 200 before relative displacement occurs between the display screens 100 in the arrangement direction of two adjacent display screens 100 (in the initial setting state of the display device 200) is defined as m. The length of the light-shielding area 73 in the arrangement direction of two adjacent display screens 100 in this disclosure can be (1 / 5) × m, so as 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 of the first filter area 71 and the light of the second filter area 72 when the colors of the light on the first filter area 71 and the light on the second filter area 72 are different.

[0145] In the initial setting state of the display device 200, in the arrangement direction of the two adjacent display screens 100: the size of the first splicing color resist block 624 is L1, and the size of the first filter part projected onto the first splicing color resist block 624 can be in the range of (1 / 3)L1~(1 / 2)L1; the size of the second splicing color resist block 625 is L2, and the size of the second filter part projected onto the second splicing color resist block 625 can be in the range of (1 / 3)L2~(1 / 2)L2.

[0146] In some embodiments, the reflective structure may include a first reflective surface 81 and a second reflective surface 82. The first reflective surface 81 faces the first color resist block 624, and the second reflective surface 82 faces the second color resist block 625. The first reflective surface 81 and the second reflective surface 82 are configured to guide light emitted from two adjacent color resist blocks to the display surface of the display device 200.

[0147] Specifically, the first reflective surface 81 guides the light emitted from adjacent splicing surfaces to the first filter area 71, where it is filtered before being emitted onto the display surface of the display device 200. Similarly, the second reflective surface 82 guides the light emitted from adjacent splicing surfaces to the second filter area 72, where it is filtered before being emitted onto the display surface of the display device 200. By reflecting the light from adjacent splicing surfaces using the first reflective surface 81 and the second reflective surface 82, the utilization rate of the light emitted from the splicing surfaces can be improved, thereby increasing the display brightness of the display surface and the corresponding area of ​​the seam.

[0148] In this disclosure, the top edge of the first reflective surface 81 (that is, the side of the first reflective surface 81 that is close to the display surface of the display device 200) may not be lower than the top surface of the adjacent reflective structure 5 (that is, the side of the reflective structure 5 that is close to the display surface of the display device 200), and the bottom edge of the first reflective surface 81 (that is, the side of the first reflective surface 81 that is far from the display surface of the display device 200) may not be higher than the bottom surface of the adjacent reflective structure 5 (that is, the side of the reflective structure 5 that is far from the display surface of the display device 200), so as to increase the area of ​​the first reflective surface 81, thereby reflecting more light emitted from the splicing surface and improving the brightness of the light emitted from the first filter area 71.

[0149] The top edge of the second reflective surface 82 (that is, the side of the second reflective surface 82 closest to the display surface of the display device 200) can be no lower than the top surface of the adjacent reflective structure 5, and the bottom edge of the second reflective surface 82 (that is, the side of the second reflective surface 82 furthest from the display surface of the display device 200) can be no higher than the bottom surface of the adjacent reflective structure 5, so as to increase the area of ​​the second reflective surface 82, 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 display surface of the display device 200 and the splicing area, improving the problem of black borders appearing in the splicing area of ​​the display device 200.

[0150] In some embodiments, the angle between the first reflective surface 81 and the display surface of the display device 200 may be smaller than the angle between the corresponding adjacent second reflective layer 52 and the display surface of the display device 200, and the angle between the first reflective surface 81 and the display surface of the display device 200 may be smaller than the angle between the corresponding adjacent third reflective layer 53 and the display surface of the display device 200; the angle between the second reflective surface 82 and the display surface of the display device 200 may be smaller than the angle between the corresponding adjacent second reflective layer 52 and the display surface of the display device 200, and the angle between the second reflective surface 82 and the display surface of the display device 200 may be smaller than the angle between the corresponding adjacent third reflective layer 53 and the display surface of the display device 200. When light from the second reflective layer 52 and the third reflective layer 53 is reflected onto the first reflective surface 81 and the second reflective surface 82, the light can be diffused and reflected by the first reflective surface 81 and the second reflective surface 82. As a result, the reflected light can fill the entire seam area, improving the uniformity of light output between the display surface of the display device 200 and the corresponding area of ​​the seam area, thereby improving the overall display effect of the display device 200.

[0151] However, this disclosure may also make the angle between the first reflective surface 81 and the display surface of the display device 200 equal to the angle between the corresponding adjacent second reflective layer 52 and the display surface of the display device 200 (i.e., the first reflective surface 81 is parallel to the corresponding adjacent second reflective layer 52), and the angle between the second reflective surface 82 and the display surface of the display device 200 equal to the angle between the corresponding adjacent second reflective layer 52 and the display surface of the display device 200 (i.e., the second reflective surface 82 is parallel to the corresponding adjacent second reflective layer 52).

[0152] Alternatively, the angle between the first reflective surface 81 and the display surface of the display device 200 can be equal to the angle between the corresponding adjacent third reflective layer 53 and the display surface of the display device 200 (i.e., the first reflective surface 81 is parallel to the corresponding adjacent third reflective layer 53), and the angle between the second reflective surface 82 and the display surface of the display device 200 can be equal to the angle between the corresponding adjacent third reflective layer 53 and the display surface of the display device 200 (i.e., the second reflective surface 82 is parallel to the corresponding adjacent third reflective layer 53). The specific angle can be determined according to the actual situation.

[0153] Taking the parallel relationship between the first reflective surface 81 and the second reflective layer 52 as an example: when the light emitted by the edge light-emitting structure 201 is perpendicular to the display surface of the display device 200, the light shines on the second reflective layer 52 and is reflected by the second reflective layer 52 to the corresponding first reflective surface 81. The light reflected by the first reflective surface 81 can be collimated and emitted in a direction perpendicular to the display surface of the display device 200, thereby reducing light loss.

[0154] In some embodiments, the angle between the first reflective surface 81 and the display surface of the display device 200 can be in the range of 30° to 45°.

[0155] For example, the angle between the first reflective surface 81 and the display surface of the display device 200 can be 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, etc., and can be determined according to the actual situation.

[0156] In this disclosure, the first reflective surface 81 and the second reflective surface 82 can be arranged in a mirror-symmetric manner about the center of the seam area. However, this is not a limitation; the first reflective surface 81 and the second reflective surface 82 may also not be arranged in a mirror-symmetric manner about the center of the seam area, depending on the actual situation.

[0157] In some embodiments, the display device 200 may further include a support structure 83, which is at least partially located within the seam area. The top surface of the support structure 83 (the side of the support structure 83 close to the display surface of the display device 200) abuts against the bottom surface of the filter (the side of the filter away from the display 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.

[0158] When the support structure 83 is located between the first reflective surface 81 and the corresponding adjacent splicing color block 621, and / or when the support structure 83 is located between the second reflective surface 82 and the corresponding adjacent splicing color block 621, the support structure 83 is light-transmitting to prevent the support structure 83 from obstructing the light emitted from the splicing surface onto the reflective structure.

[0159] For example, the reflective structure can be embedded entirely within the support structure 83, so that the support structure 83 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.

[0160] The reflective structure and the support structure 83 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 83, the support structure 83 can directly abut against the adjacent display screen 100.

[0161] However, it is not limited to this. The reflective structure and the support structure 83 can also be set at an interval between them and the adjacent display screen 100 to reserve a certain amount of space between the support structure 83 and the adjacent display screen 100, thereby improving the problem of collision and squeezing between the support structure 83 and the display screen 100.

[0162] Furthermore, the top surface of the support structure 83 can be flush with the display surfaces of the two adjacent displays 100, and the bottom surface of the filter part can abut against the display surfaces of the two adjacent displays 100, thereby increasing the support area of ​​the filter part and reducing the risk of bending and deformation of the filter part.

[0163] However, this disclosure is not limited to this. The top surface of the support structure 83 can also be higher than the display surfaces of the two adjacent display screens 100. That is, the distance between the top surface of the support structure 83 and the display surface of the display device 200 is less than the distance between the display surface of the display screen 100 and the display surface of the display device 200. This allows the light-transmitting part 74 to be spaced apart from the corresponding display screen 100, reducing the friction between the light filter and the adjacent display screen 100 when relative displacement occurs between the adjacent display screens 100, and reducing the risk of damage to the light filter and the display screen 100.

[0164] In some embodiments, the display device 200 may include a light-transmitting layer disposed on the display 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 74 and a light-filtering portion. The light-transmitting portion 74 covers the display surface of the display screen 100 and is connected to the light-filtering portion. The light-transmitting portion 74 is light-transmitting.

[0165] The light-transmitting layer may include multiple light-transmitting portions 74, each corresponding to a display screen 100, with a filter portion located between adjacent light-transmitting portions 74. Light from the display screen 100 can be emitted through the light-transmitting portions 74 to the display surface of the display device 200.

[0166] For example, the light-transmitting portion 74 in this disclosure may be a rigid glass or a rigid resin substrate that is light-transmitting.

[0167] By providing the light-transmitting portion 74, 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 display surface of the display device 200 comes into contact with the display surface of the display screen 100, the light-transmitting portion 74 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.

[0168] Furthermore, when the display device 200 includes both a support structure 83 and a light-transmitting portion 74, both the support structure 83 and the light-transmitting portion 74 can be made of a light-transmitting material. When the support structure 83 and the light-transmitting portion 74 are made of the same material, they can be arranged in the same layer. That is, light-transmitting material can be simultaneously provided in the seam area and on the display surface of the display screen 100, so that the support structure 83 and the light-transmitting portion 74 can be formed simultaneously, thereby simplifying the overall manufacturing process of the display device 200 and improving the manufacturing efficiency of the display device 200.
