[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0044] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0045] Currently, as the demand for display products such as mobile phones and wearable devices gradually increases in daily life, people have higher and higher requirements for display devices, and high-resolution and narrow-bezel display devices are becoming increasingly popular among consumers.

[0046] like Figure 1 As shown, in related technologies, the display panel includes an array substrate 11, a pixel definition layer 12, and multiple pixel units 13. The pixel definition layer 12 includes multiple pixel openings 121, and a pixel unit 13 is disposed in each pixel opening 121. The pixel unit 13 includes RGB light-emitting material, and the RGB light-emitting material specifically includes three colors: red, green, and blue.

[0047] Currently, the pixel arrangement method for high resolution is Sub Pixel Rendering (SPR), where adjacent pixel units share either red (R) or blue (B) subpixels. However, this pixel arrangement has drawbacks such as inconsistent line widths between bright and dark areas and insufficient physical resolution. Real RGB pixel arrangement solves the problems of the current SPR algorithm, where subpixels are not shared by other pixel units. However, when depositing subpixels using a Fine Metal Mask (FMM), the precision limitations of the FMM require that the subpixel spacing not be too small. Therefore, when Real RGB pixel arrangement is used for high-resolution displays, the aperture ratio of the subpixels drops drastically, and parameters such as display lifespan also decrease significantly.

[0048] Limited by the RGB light-emitting material evaporation process and the pixel isolation (PDL) process, it is difficult to further increase the pixel density of display panels. Pixel isolation technology involves creating isolation structures between pixels.

[0049] In addition, such as Figure 2 As shown, the display panel includes a bezel area 103. The bezel area 103 has multiple metal traces; in other words, the existence of the bezel area 103 is due to the presence of these metal traces. A cover plate 20 is provided on the light-emitting side of the display panel. To prevent reflected light from the metal traces in the bezel area 103 from affecting the display effect, a light-absorbing ink layer 201 is typically coated around the bottom periphery of the cover plate 20. The presence of the ink layer 201 also blocks light emitted from the display panel from reaching the area above it, thus forming a display bezel at the edge of the cover plate 20. Furthermore, in practice, there are tolerances in the coating of the ink layer 201 and the adhesion of the cover plate 20. Therefore, to ensure the light-blocking effect of the ink layer 201, it is generally necessary to appropriately increase the coverage area of ​​the ink layer 201 and increase the size of the cover plate 20, which leads to a further increase in the size of the display bezel. To achieve a narrow bezel, the screen wiring is usually compressed to reduce the size of the bezel area 103 of the display panel; or, the processing tolerance and bonding tolerance of the ink layer 201 of the cover plate 20 are improved. However, the wiring design, material tolerance, and manufacturing capabilities cannot be compressed indefinitely, and the display bezel is difficult to shrink further.

[0050] Based on this, this application provides a display panel, a display module, and a display device to solve the above-mentioned technical problems, as detailed in the following embodiments.

[0051] Reference Figure 3 , Figure 4As shown, one embodiment of this application discloses a display panel 100. The display panel 100 includes a display area, which includes a first display area 101. The display panel 100 includes an array substrate 11, a pixel definition layer 12, a plurality of pixel units 13, and a plurality of light guide structures 14. At least a portion of the array substrate 11 is located in the first display area 101. The pixel definition layer 12 is located on one side of the array substrate and in the first display area 101. The pixel definition layer 12 includes a plurality of pixel openings 121. The plurality of pixel units 13 are respectively located in the corresponding pixel openings 121. The light guide structures 14 are located on the side of the pixel units 13 away from the array substrate 11. Each light guide structure 14 is used to divide the light emitted by the corresponding pixel unit 13 to form a plurality of sub-pixels 131.

[0052] First, it should be noted that, unless otherwise specified, in each embodiment of this application, "multiple" refers to at least two.

[0053] The display panel 100 provided in this application embodiment divides the light emitted by a single pixel unit 13 into multiple sub-pixels 131 through the light guide structure 14, which can increase the number of pixels arranged on the array substrate 11, thereby increasing the pixel density. That is, the display device can present more pixels under the same physical size, thereby achieving high-resolution display and providing more delicate and clearer images, while eliminating the need to increase the requirements for the vapor deposition process of the light-emitting material in the pixel unit 13 and the process of the pixel definition layer 12.

[0054] Specifically, on the array substrate 11, multiple pixel units 13 are arranged in an orderly manner through circuitry and layout. Each pixel unit 13 contains a light-emitting material (such as organic light-emitting material in an OLED). These light-emitting materials can emit light of specific colors under the influence of current, including three different colors: red (R), green (G), and blue (B). By controlling the light-emitting state of each pixel unit 13 on the array substrate 11, various images and text can be formed.

[0055] Reference Figure 3 As shown, in one embodiment, each light guide structure 14 includes a plurality of microfibers, at least some of which guide the light from the subpixel 131 to the first display area 101.

[0056] The display panel 100 provided in this application embodiment has multiple micro-optical fibers in the light guide structure 14 guiding the light from multiple sub-pixels formed by the corresponding pixel units 13 in each pixel opening 121. In each sub-pixel, some or all of the light passes through each film layer structure to form a first display area 101 on the light-emitting side of the display panel 100, which can realize the main display function of the first display area 101; or some of the light may fall on the outside of the first display area 101 to realize other auxiliary display functions.

[0057] For example, microfibers are typically made by heating, melting, stretching and thinning standard communication optical fibers, and include optical waveguides with diameters ranging from several micrometers to hundreds of nanometers.

[0058] Reference Figure 3 , Figure 5 As shown, in one embodiment, the microfiber extends along a first direction, that is, the first direction is the extension direction of the microfiber, and the first direction is set at an angle to the plane where the pixel definition layer 12 is located. Here, the first direction is the length direction of the microfiber, and the angle setting means that the two are not parallel. By setting the microfiber at an angle to the plane where the pixel definition layer 12 is located, the light of the sub-pixel can be propagated along a specific angle to adjust the light emission position so that it falls on a specific area.

[0059] Reference Figure 3 As shown, in one embodiment, the angle between the first direction and the plane where the pixel definition layer 12 is located is 90 degrees. By making the micro-fiber in the light guide structure 14 perpendicular to the plane where the pixel definition layer 12 is located, the light from the sub-pixels in the micro-fiber propagates towards the light-emitting side in a direction perpendicular to the display panel 100, resulting in a better display effect in the first display area 101.

[0060] Reference Figure 5 As shown, in another embodiment, the angle between the first direction and the plane where the pixel definition layer 12 is located is an angle other than 90 degrees, such as 15 degrees, 30 degrees, 45 degrees, etc. While extending towards the light-emitting side of the display panel 100, the microfiber also tilts towards the outer periphery of the display panel 100. Therefore, the light emission position of the sub-pixels in the microfiber will be outside the first display area 101, thereby expanding the display area range of the display panel 100.

[0061] Reference Figure 6 , Figure 7 As shown, in one embodiment, each light guide structure 14 includes at least a first microfiber 141 and a second microfiber 142, which are arranged at an angle. By using the first microfiber 141 and the second microfiber 142 in different directions within each light guide structure 14, the light from the corresponding sub-pixel can be guided in different directions, thereby increasing the display area range corresponding to each pixel unit 13 compared to guiding the light in the same direction.

[0062] In one embodiment, the first micro-optical fiber 141 or the second micro-optical fiber 142 is perpendicular to the plane where the pixel definition layer 12 is located. By ensuring that at least one micro-optical fiber in the light guide structure 14 is perpendicular to the plane where the pixel definition layer 12 is located, at least a portion of the light rays in the pixel unit 13 are located in the first display area 101, thus ensuring basic display functionality.

[0063] Reference Figure 7 , Figure 8 As shown, in one embodiment, each light guide structure 14 further includes a third microfiber 143 to divide the corresponding pixel unit 13 into at least three sub-pixels 131. By providing at least three microfibers in each light guide structure 14 to divide the corresponding pixel unit 13 into at least three sub-pixels 131, the pixel density of the display panel 100 is further increased. Optionally, at least the first microfiber 141 and the second microfiber 142 of the three microfibers corresponding to the three sub-pixels 131 are arranged at an angle, or the first microfiber 141, the second microfiber 142, and the third microfiber 143 are arranged at angles to each other in pairs.

[0064] Reference Figure 6 As shown, in one embodiment, the display area of ​​the display panel 100 includes a second display area 102, which is located at least on one side of the first display area 101, and a portion of the micro-fiber guides the light of the corresponding sub-pixel 131 to the second display area 102.

[0065] The display panel 100 provided in this application embodiment has some sub-pixels 131 of the pixel unit 13 located at the edge of the first display area 101 guided to the second display area 102 through micro-optical fiber, which can act as ink. There is no need to make an ink layer on the corresponding cover plate, so there is no ink material tolerance or ink bonding tolerance, which can achieve the effect of reducing the bezel.

[0066] In one embodiment, the color of the light in the second display area 102 includes at least one of white, red, green, and blue. Guided by a portion of the micro-optical fiber, some sub-pixels 131 in the pixel unit 13 can function as ink. Since the light emitted by the pixel unit 13 includes three different colors—red, green, and blue—the color of the border in the second display area 102 is adjustable.

[0067] Specifically, the array substrate 11 may include circuit structures such as driving circuits and / or touch circuits and / or detection circuits. The metal traces of each circuit structure are generally led out to the edge of the array substrate 11 and then connected to specific circuit devices or circuit structures, such as driving chips or control chips. These metal traces cause the edge of the array substrate 11 to form a trace area, and the existence of the trace area results in the presence of a bezel area 103 on the periphery of the existing display panel 100.

[0068] Reference Figure 9 As shown, in one embodiment, the pixel definition layer 12 includes a plurality of light-shielding portions 120, and a pixel opening 121 is provided between adjacent light-shielding portions 120.

[0069] Preferably, the display panel 100 further includes a non-display area 104, which is disposed around at least a portion of the display area. At least a portion of the light-shielding portion 120 is located in the non-display area 104. The array substrate 11 includes a first trace 16 located in the non-display area 104. The orthographic projection of the light-shielding portion 120 on the array substrate 11 covers the orthographic projection of the first trace 16 on the array substrate 11.

[0070] The display panel 100 provided in this embodiment can block incident light that may be received by the metal traces and block light reflected from the metal traces through the light-shielding part 120. Thus, since the light-shielding part 120 can solve the problem of reflected light from the metal traces affecting the display effect, an ink layer is no longer needed around the bottom perimeter of the cover plate. This reduces the problem of increased display bezel caused by the ink layer and simplifies the manufacturing process.

[0071] In one embodiment, the light-shielding portion 120 may be made of a black material. Of course, the light-shielding portion 120 may also be made of light-absorbing materials of other colors.

[0072] The pixel definition layer 12 uses a light-shielding part 120 to block the metal traces at the edge of the display panel 100. No ink is needed on the cover plate, thus achieving a borderless display. In this case, a super-large screen display can be achieved by seamlessly splicing multiple display panels 100.

[0073] It should be noted that, corresponding to the position of the light-shielding part 120 of the pixel definition layer 12 in this embodiment, in conventional schemes, the pixel definition layer 12 adopts a pixel definition part made of a light-transmitting material.

[0074] In some embodiments, the display panel 100 further includes an encapsulation layer 15, which is located on the side of the pixel definition layer 12 away from the array substrate 11. The encapsulation layer 15 primarily serves to prevent the intrusion of moisture and other contaminants, protecting structures such as the pixel units 13 and extending the lifespan of the display panel 100. The encapsulation layer 15 may be a thin-film encapsulation layer (TFE).

[0075] Based on the same inventive concept, another embodiment of this application also provides a display module 200.

[0076] Reference Figure 10 , Figure 11As shown, the display module 200 includes the display panel 100 in the above embodiment. The display module 200 also includes a touch layer 23, a polarizing layer 22, an optical adhesive layer 21, and a cover plate 20 stacked sequentially. The touch layer 23 is located on the side of the pixel definition layer 12 away from the array substrate 11; the polarizing layer 22 is located on the side of the touch layer 23 away from the array substrate 11; the optical adhesive layer 21 is located on the side of the polarizing layer 22 away from the array substrate 11; and the cover plate 20 is located on the side of the optical adhesive layer 21 away from the array substrate 11. The light guide structure 14 connects the pixel unit 13 and the polarizing layer 22, and passes through the encapsulation layer 15 and the touch layer 23.

[0077] In the display module 200 provided in this application embodiment, a single pixel unit 13 is divided into multiple sub-pixels 131 by a light guide structure 14, which can increase the number of pixels arranged on the array substrate 11, thereby increasing the pixel density. That is, the display module can present more pixels under the same physical size, thereby achieving high-resolution display and providing more delicate and clearer images. At the same time, there is no need to increase the requirements for the evaporation process of the light-emitting material in the pixel unit 13 and the requirements for the pixel definition layer 12 process.

[0078] Reference Figure 10 As shown, in one embodiment, the display panel 100 includes a second display area 102, which is located at least on one side of the first display area 101, and a portion of the microfiber guides the light of the corresponding sub-pixel 131 to the second display area 102.

[0079] Among them, some sub-pixels 131 of the pixel unit 13 located at the edge of the first display area 101 are guided to the second display area 102 through micro-optical fiber and can act as ink. There is no need to make an ink layer on the corresponding cover plate 20, so there is no ink material tolerance or ink bonding tolerance, which can achieve the effect of reducing the bezel.

[0080] Reference Figure 11 As shown, in one embodiment, the pixel definition layer 12 includes a plurality of light-shielding portions 120, and a pixel opening 121 is provided between adjacent light-shielding portions 120.

[0081] Preferably, the display panel 100 further includes a non-display area 104, which surrounds at least a portion of the display area. At least a portion of the light-shielding portion 120 is located in the non-display area 104. The array substrate 11 includes a first trace 16 located in the non-display area 104. The orthographic projection of the light-shielding portion 120 onto the array substrate 11 covers the orthographic projection of the first trace 16 onto the array substrate 11. The display area includes at least a first display area 101.

[0082] The light-shielding portion 120 in the pixel definition layer 12 can block incident light that may be received by the metal traces, as well as light reflected from the metal traces. Thus, since the light-shielding portion 120 solves the problem of reflected light from the metal traces affecting the display effect, an ink layer is no longer needed around the bottom perimeter of the cover plate 20. This reduces the problem of increased display bezels caused by the ink layer and simplifies the manufacturing process.

[0083] In this process, the pixel definition layer 12 uses a light-shielding part 120 to block the metal traces at the edge of the display panel 100, and no ink is needed on the cover plate 20, thus achieving a borderless display.

[0084] Reference Figure 12 As shown, in one embodiment, in the case of borderless display, the display module 200 includes multiple seamlessly spliced ​​display panels 100, which can realize ultra-large screen display.

[0085] Based on the same inventive concept, another embodiment of this application provides a display device, which includes the display module 200 in the above embodiments. Furthermore, the display device includes mobile phones, VR devices, computers, televisions, in-vehicle display devices, etc.

[0086] The display device provided in this application embodiment divides a single pixel unit 13 into multiple sub-pixels 131 through a light guide structure 14, which can increase the number of pixels arranged on the array substrate 11, thereby increasing the pixel density. That is, the display module can present more pixels under the same physical size, thereby achieving high-resolution display and providing more delicate and clearer images. At the same time, it does not require additional requirements for the evaporation process of the light-emitting material in the pixel unit 13 or for the process of the pixel definition layer 12.

[0087] Although this application has been described in conjunction with specific embodiments thereof, many substitutions, modifications and variations of these embodiments will be apparent to those skilled in the art from the foregoing description.

Furthermore, the processes depicted in the drawings do not necessarily require a specific or sequential order to achieve the desired result.
