Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0042] The inventors discovered that when related technologies splice the display screen and the support plate with transparent optical adhesive, they usually do not treat the splicing seam between adjacent display screens. The reflected light at the splicing seam may make the visual appearance at the splicing seam obvious, which is not conducive to the overall display effect of the display module and affects the user experience.
[0043] To address this problem, the inventors have innovatively designed the following technical solutions, which will be described in detail below with reference to the accompanying drawings. It should be noted that the deficiencies in the existing solutions described above are the result of the inventors' practical experience and careful research. Therefore, the discovery process of the aforementioned technical problems and the solutions proposed in this embodiment below are contributions made by the inventors to this application during the invention process, and should not be construed as technical content known to those skilled in the art.
[0044] Please refer to Figure 1 This application provides a display module 10, including a display layer 110, a light-transmitting layer 120 and an absorption layer 130. The display layer 110 includes at least two spliced displays 111 and a splicing seam 112 located between two adjacent displays 111. The displays 111 may include Mini-LED displays, Micro-LED displays, etc.
[0045] The light-transmitting layer 120 is located on the light-emitting side of the display layer 110, and the absorption layer 130 is located between the light-transmitting layer 120 and the display layer 110. The orthographic projection of the splicing seam 112 on the light-transmitting layer 120 and the orthographic projection of the absorption layer 130 on the light-transmitting layer 120 at least partially overlap, meaning that the width of the absorption layer 130 is less than, equal to, or greater than the width of the splicing seam 112. The absorption layer 130 can absorb the reflected light transmitted through the splicing seam 112, reducing the reflected light received by the human eye and achieving the effect of weakening the visual perception of the splicing seam 112. Specifically, the display layer 110 can be single-sided or double-sided light-emitting. When the display layer 110 is single-sided light-emitting, please refer to... Figure 2 The display module 10 may also include a support backplate 150 located on the opposite side of the light-emitting side of the display layer 110.
[0046] In the above structure, by setting an absorption layer 130 inside the light-transmitting layer 120 at the corresponding position of the splicing seam 112, the reflected light at the splicing seam 112 can be effectively absorbed, the reflected light received by the human eye can be reduced, the visual effect of the splicing seam 112 can be weakened, the overall display effect of the entire display module can be improved, the user experience can be enhanced, and the market competitiveness of the product can be increased.
[0047] Furthermore, when the width of the absorption layer 130 is less than or equal to the width of the splicing seam 112, it is mainly used to absorb reflected light emitted from the front of the splicing seam 112; while when the width of the absorption layer 130 is greater than the width of the splicing seam 112, it can absorb not only reflected light emitted from the front of the splicing seam 112, but also reflected light emitted from the side of the splicing seam 112. Preferably, the width of the absorption layer 130 is greater than the width of the splicing seam 112 to ensure that the absorption layer 130 can effectively absorb reflected light transmitted through the splicing seam 112. However, in order to reduce the impact of the absorption layer 130 on the overall light transmittance of the display module 10, in the direction parallel to the plane where the display layer 110 is located and perpendicular to the splicing seam 112, the width of the absorption layer 130 is less than or equal to 5W1, where W1 is the width of the splicing seam 112, that is, the orthographic projection of the absorption layer 130 on the light-transmitting layer 120 overlaps with the orthographic projection of the display screen 111 on the light-transmitting layer 120.
[0048] Furthermore, in actual manufacturing, due to process limitations, it is difficult to perfectly align the central axis of the absorption layer 130 with the central axis of the seam 112. To reduce these limitations, the length of the absorption layer 130 extending relative to the edge of the seam 112 in a direction parallel to the plane of the display layer 110 and perpendicular to the seam 112 is less than or equal to 2W1. This ensures that even if the central axes are not perfectly aligned, the absorption layer 130 can still effectively absorb reflected light emitted from the front and sides of the seam 112, reducing the visual impact at the seam. The thickness d1 of the display screen 111 in the direction perpendicular to the light-transmitting layer 120 ranges from 0.05mm to 2mm. For example, the thickness d1 of the display screen 111 in the direction perpendicular to the light-transmitting layer 120 includes 0.05mm, 0.1mm, 0.3mm, 0.5mm, 1mm, 1.5mm, 1.75mm, 1.9mm, and 2mm, etc. The thickness d2 of the adhesive layer 140 in the direction perpendicular to the light-transmitting layer 120 ranges from 0.01mm to 1mm. For example, the thickness d2 of the adhesive layer 140 in the direction perpendicular to the light-transmitting layer 120 includes 0.01mm, 0.05mm, 0.15mm, 0.2mm, 0.5mm, 0.75mm, 0.9mm, 0.95mm, and 1mm, etc.
[0049] The absorption layer 130 includes a transparent medium and reflective particles filled in the transparent medium. The absorption efficiency of the absorption layer 130 is greater than or equal to the light transmittance of the display module 10. For example, when the light transmittance of the display module 10 is 70%, the absorption efficiency of the absorption layer 130 should be greater than or equal to 70% to ensure that the absorption layer 130 can absorb sufficient reflected light and weaken the visual appearance at the splicing seam 112. To ensure the optical consistency of the display module 10, the difference between the light transmittance of the absorption layer 130 and the light transmittance of the light-transmitting layer 120 is less than 1%. Preferably, the light-transmitting layer 120 can be made of a high-transmittance material with a light transmittance greater than or equal to 95%. For example, the light-transmitting layer 120 can be made of AR glass with a light transmittance greater than or equal to 95%, or it can be formed by multiple laminations of a flowable adhesive with a light transmittance greater than or equal to 95% and a solid optically transparent adhesive.
[0050] In the direction perpendicular to the plane of the display layer 110, the thickness of the absorption layer 130 is less than or equal to one-twentieth of the thickness of the light-transmitting layer 120. This can effectively reduce the delamination phenomenon caused by the difference in thickness of the absorption layer 130 between the light-transmitting layer 120 and the display layer 110, thereby ensuring that the surface of the laminated display module 10 is flat and improving the lamination quality.
[0051] Furthermore, please refer to [the website / platform] again. Figure 2 The display module 10 also includes an adhesive layer 140 located between the display layer 110 and the light-transmitting layer 120, and an absorption layer 130 located between the adhesive layer 140 and the light-transmitting layer 120. The adhesive layer 140 can tightly bond the display layer 110 and the light-transmitting layer 120, improving the overall reliability and stability of the display module 10. To ensure the light emission effect of the display module 10, the adhesive layer 140 can be made of an optical adhesive with high transparency and high bonding strength. For example, the adhesive layer 140 can be an OCA (Optically Clear Adhesive) optical adhesive layer.
[0052] In some possible embodiments, please refer to Figure 3 The display layer 110 includes a first light-transmitting side and a second light-transmitting side opposite to each other, the light-transmitting layer 120 includes a first light-transmitting layer 121 and a second light-transmitting layer 122, and the absorption layer 130 includes a first absorption layer 131 and a second absorption layer 132.
[0053] The first light-transmitting layer 121 and the first absorption layer 131 are located on the first light-transmitting side, with the first absorption layer 131 positioned between the first light-transmitting layer 121 and the display layer 110. The second light-transmitting layer 122 and the second absorption layer 132 are located on the second light-transmitting side, with the second absorption layer 132 positioned between the second light-transmitting layer 122 and the display layer 110. The first absorption layer 131 absorbs reflected light emitted from the seam 112 towards the first light-emitting side, and the second absorption layer 132 absorbs reflected light emitted from the seam 112 towards the second light-emitting side.
[0054] In the above structure, by setting a first absorption layer 131 and a second absorption layer 132 corresponding to the position of the splicing seam 112 on the first light-emitting side and the second light-emitting side, the reflected light at the splicing seam 112 can be effectively absorbed, the reflected light received by the human eye can be reduced, and the visual perception of the splicing seam 112 can be weakened.
[0055] Furthermore, the adhesive layer 140 includes a first adhesive layer 141 and a second adhesive layer 142. The first adhesive layer 141 is located between the display layer 110 and the first light-transmitting layer 121. The first absorption layer 131 is located on the side of the first adhesive layer 141 away from the display layer 110. The second adhesive layer 142 is located between the display layer 110 and the second light-transmitting layer 122. The second absorption layer 132 is located on the side of the second adhesive layer 142 away from the display layer 110.
[0056] Based on the same inventive concept, this application also provides a method for manufacturing a display module 10, for details please refer to Figure 4 and Figure 5 , Figure 4 A flowchart illustrating the manufacturing process of module 10 is provided. Figure 5 for Figure 4 The corresponding process flow diagram. (See below for details.) Figure 4 and Figure 5 The manufacturing process of the display module 10 is described in detail.
[0057] Step S110: Provide a light-transmitting layer.
[0058] In this step, the light-transmitting layer 120 can be made of a high-transmittance material with a light transmittance greater than or equal to 95%. For example, the light-transmitting layer 120 can be made of AR glass with a light transmittance greater than or equal to 95%, or the light-transmitting layer 120 can be formed by multiple laminations of flowable adhesive and solid optical transparent adhesive with a light transmittance greater than or equal to 95%.
[0059] Step S120: Create an absorption layer on one side of the light-transmitting layer.
[0060] In this step, an absorption layer 130 can be coated on one side of the light-transmitting layer 120. The absorption layer 130 includes a transparent medium and reflective particles filled in the transparent medium. Specifically, the width of the absorption layer 130 can be less than or equal to the width of the splicing seam 112, or it can be greater than the width of the splicing seam 112. Preferably, the width of the absorption layer 130 is greater than the width of the splicing seam 112, so that it can absorb the reflected light emitted from the front of the splicing seam 112, as well as the reflected light emitted from the side of the splicing seam 112, thereby ensuring that the absorption layer 130 can effectively absorb the reflected light transmitted through the splicing seam 112. However, in order to reduce the impact of the absorption layer 130 on the overall light transmittance of the display module 10, the width of the absorption layer 130 in the direction parallel to the plane where the display layer 110 is located and perpendicular to the splicing seam 112 is less than or equal to 5W1, where W1 is the width of the splicing seam 112. Furthermore, in order to reduce process limitations, the length of the absorption layer 130 extending relative to the edge of the splice seam 112 in a direction parallel to the plane where the display layer 110 is located and perpendicular to the splice seam 112 is less than or equal to 2W1.
[0061] Next, an adhesive layer 140 can be formed on the side of the absorption layer 130 away from the light-transmitting layer 120 to adhere to the display screen 111. In order to ensure the light emission effect of the display module 10, the adhesive layer 140 can be made of an optical adhesive with high transparency and high bonding strength. For example, OCA (Optically Clear Adhesive) optical adhesive can be coated on the side of the absorption layer 130 away from the light-transmitting layer 120 to obtain the adhesive layer 140.
[0062] Step S130: Splice at least two displays on one side of the light-transmitting layer to form the absorption layer, and make the orthographic projection of the absorption layer on the light-transmitting layer at least partially coincide with the orthographic projection of the splicing seam between adjacent displays on the light-transmitting layer.
[0063] In this embodiment, by providing an absorption layer 130 inside the light-transmitting layer 120 at the corresponding position of the splicing seam 112, the reflected light at the splicing seam 112 can be effectively absorbed, reducing the reflected light received by the human eye and achieving the effect of weakening the visual perception of the splicing seam 112.
[0064] Further, please refer to Figure 6 and Figure 7 When the display layer 110 includes a first light-transmitting side and a second light-transmitting side, the display module 10 can be manufactured according to the following method.
[0065] Step S210: Provide a first light-transmitting layer and a second light-transmitting layer.
[0066] In this step, a high-transmittance material with a transmittance greater than or equal to 95% can be used to fabricate the first light-transmitting layer 121 and the second light-transmitting layer 122 respectively. For example, the first light-transmitting layer 121 and the second light-transmitting layer 122 can be AR glass with a transmittance greater than or equal to 95%, or formed by multiple laminations of a flowable adhesive with a transmittance greater than or equal to 95% and a solid optical transparent adhesive.
[0067] Step S220: A first absorption layer is formed on one side of the first light-transmitting layer, and a second absorption layer is formed on one side of the second light-transmitting layer.
[0068] In this step, the first absorption layer 131 and the second absorption layer 132 include a transparent medium and reflective particles filled in the transparent medium.
[0069] After step S220, a first adhesive layer 141 can be formed on the side of the first absorption layer 131 away from the first light-transmitting layer 121 using an optical adhesive with high transparency and high bonding strength, and a second adhesive layer 142 can be formed on the side of the second absorption layer 132 away from the second light-transmitting layer 122.
[0070] Step S230: At least two displays are spliced together on one side of the first light-transmitting layer to form the first absorption layer, and the displays after being bonded to the first light-transmitting layer are bonded to the side of the second light-transmitting layer to form the second absorption layer.
[0071] In this step, the first light-transmitting layer 121 and the first absorption layer 131 are located on the first light-transmitting side, and the first absorption layer 131 is located between the first light-transmitting layer 121 and the display layer 110. The second light-transmitting layer 122 and the second absorption layer 132 are located on the second light-transmitting side, and the second absorption layer 132 is located between the second light-transmitting layer 122 and the display layer 110. The first absorption layer 131 can absorb reflected light emitted from the splicing seam 112 towards the first light-emitting side, and the second absorption layer 132 can absorb reflected light emitted from the splicing seam 112 towards the second light-emitting side. The orthographic projection of the first absorption layer 131 and the second absorption layer 132 on the display layer 110 at least partially overlaps with the splicing seam 112 between two adjacent display screens 111. Preferably, the width of the first absorption layer 131 and the second absorption layer 132 is greater than the width of the splicing seam 112. While absorbing the reflected light emitted from the front of the splicing seam 112, it can also absorb the reflected light emitted from the side of the splicing seam 112, thereby ensuring that the absorption layer 130 can effectively absorb the reflected light transmitted through the splicing seam 112.
[0072] In this embodiment, when the display module 10 emits light from both sides, a first absorption layer 131 and a second absorption layer 132 corresponding to the position of the splicing seam 112 can be respectively provided on the first light-emitting side and the second light-emitting side. The first absorption layer 131 and the second absorption layer 132 absorb the reflected light emitted from the splicing seam 112, reduce the reflected light received by the human eye, and achieve the effect of weakening the visual perception of the splicing seam 112.
[0073] In addition, this application also provides an electronic device, which includes the display module 10 in any of the above embodiments. The display module 10 has an absorption layer 130 disposed inside the light-transmitting layer 120 at the position corresponding to the splicing seam 112. This absorption layer 130 can effectively absorb the reflected light transmitted through the splicing seam 112, reduce the reflected light received by the human eye, achieve the effect of weakening the visual perception of the splicing seam 112, improve the overall display effect of the entire display module, enhance the user experience, and increase the market competitiveness of the product.
[0074] In summary, this application provides a display module, a method for manufacturing the display module, and an electronic device. The display module includes a display layer, a light-transmitting layer, and an absorption layer. The light-transmitting layer is located on the light-emitting side of the display layer, and the absorption layer is located between the light-transmitting layer and the display layer. The orthographic projection of the seam onto the light-transmitting layer at least partially overlaps with the orthographic projection of the absorption layer onto the light-transmitting layer. By providing an absorption layer inside the light-transmitting layer at the corresponding position of the seam, reflected light transmitted through the seam can be effectively absorbed, reducing the reflected light received by the human eye and thus weakening the visual perception of the seam.
