Accordingly, the use of ordinal, directional and positional terms is to be considered as illustrative and understood in the present application and not restrictive. In the drawings, elements having similar structures are denoted by the same reference numerals.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic top view structure diagram of a display panel according to an embodiment of the present disclosure. Fig. 2 is a schematic cross-sectional view of the display panel shown in fig. 1 along line AA'. The display panel 100 includes an array substrate 110, an insulating layer 120, a light reflecting coating 130, and a light emitting element 140.
The array substrate 110 includes a substrate layer 111, a gate layer 112, a gate insulating layer 113, an active layer 114, a source drain layer 115, and an ohmic contact layer 116. The gate layer 112 is disposed on the substrate layer 111. A gate insulating layer 113 is disposed on one side of the substrate layer 111 and covers the gate layer 112. The active layer 114 is disposed on the gate insulating layer 113. The source drain layer 115 is disposed on the active layer 114 and on the gate insulating layer 113. An ohmic contact layer 116 is disposed between the active layer 114 and the source and drain layers 115. The substrate layer 111 is made of a glass substrate. The material of the gate layer 112 is at least one of molybdenum metal or titanium metal. The material of the active layer 114 is at least one of indium gallium zinc oxide or indium zinc tin oxide. The source drain layer 115 is made of at least one of molybdenum, aluminum, copper or titanium. The material of the gate insulating layer 113 is at least one of silicon nitride, silicon oxide, and silicon oxynitride.
And an insulating layer 120 disposed on one side of the array substrate 110, specifically on the source drain layer 115 and the gate insulating layer 113. The insulating layer 120 is provided with an open window region 121. The open window region 121 is used to expose a portion of the array substrate 110. The array substrate 110 of the open window region 121 electrically contacts the light emitting device 140. Specifically, the window region 121 exposes a portion of the source drain layer 115. The source/drain layer 115 of the open window region 121 is electrically connected to the light emitting device 140. Referring to fig. 1, the insulating layer 120 is provided with a receiving region D (a region between the dotted line frames B and B' in fig. 1) near a boundary of the open window region 121, the receiving region D is used for providing a receiving portion 122 (not shown in fig. 2), and the receiving portion 122 is used for receiving the reflective coating 130.
And the light reflecting coating 130 is arranged on one side of the insulating layer 120 far away from the array substrate 110. The Mini-LED and Micro-LED devices have a relatively large light emission angle and have divergence, so that part of the light may downwardly irradiate the thin film transistors and other devices in the array substrate 110, and long-time irradiation may affect the devices, such as aging of the devices due to temperature rise. In addition, light can be emitted in the direction opposite to the display direction of the display panel, so that the problems of low luminous efficiency of the Mini-LED and the Micro-LED devices and the like are caused. Therefore, in order to prevent the light emitted from the light emitting elements 140 from affecting the performance of the array substrate 110 and to improve the utilization rate of the light of the display panel 100, a light reflecting coating 130 needs to be coated on the array substrate 110. The reflective coating 130 is generally made of reflective paint such as white oil by a spraying process. However, in the spraying process, the reflective coating may flow toward the window area 121 along the insulating layer 120, so as to easily cover the window area 121, and the window area 121 has poor cleanliness, which may affect the electrical contact between the light emitting element 140 and the source/drain layer 115, thereby reducing the stability of the display panel 100 and the yield of the display device. In this embodiment, the accommodating portion 122 that prevents the reflective paint from flowing to the window 121 is disposed on the insulating layer 120 near the boundary of the window 121, and the accommodating portion 122 can accommodate the reflective paint flowing to the window 121, so as to maintain the cleanliness of the window 121 and improve the manufacturing accuracy of the display panel 100.
In some embodiments, the receiving portion 122 is annular on the insulating layer 120. The plurality of receiving portions 122 sequentially surround the window 121 in a direction away from the window 121. The accommodating portion 122 is disposed around the window 121, so as to maintain the cleanliness around the window 121 and prevent the reflective paint from flowing into the window 121 to prevent the window 121 for electrically connecting the light emitting elements 140.
As shown in fig. 1, the receiving portion 122 includes a first receiving portion 1221, a second receiving portion 1222, and a third receiving portion 1223. The first, second, and third accommodations 1221, 1222, and 1223 are sequentially distant from the window area 121. The first accommodating part 1221 is closest to the open window area 121. The distance between the first accommodating portion 1221 and the window area 121 is greater than the distance between the adjacent accommodating portions 122, so as to enhance the fixing property of the insulating layer 120 around the welding position of the light emitting element 140, further improve the welding stability of the light emitting element 140, and improve the production yield. In some embodiments, the plurality of receiving portions 122 may be arranged equidistantly on the insulating layer 120. In other embodiments, to further enhance the fixing of the receiving region D, the spacing between adjacent receiving portions 122 is sequentially decreased in a direction away from the window area 121, as shown in fig. 1, and the spacing between the first receiving portion 1221 and the second receiving portion 1222 is greater than the spacing between the second receiving portion 1222 and the third receiving portion 1223. It should be noted that the number of the accommodating portions 122 in the direction away from the window area 121 is not limited to 3 shown in fig. 1, and may be 5, 8, 20, 40, 50, or the like.
As shown in fig. 1, in the present embodiment, the length L of the accommodating region D in the direction away from the open window area is 10 μm to 100 μm, and may be, for example, 10 μm, 20 μm, 30 μm, 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, 90 μm, or 100 μm.
Referring to fig. 3 and 4 in conjunction with fig. 2, fig. 3 is a schematic view illustrating a first structure of a receiving portion of the display panel shown in fig. 1 before an insulating layer is sprayed with a reflective coating. Fig. 4 is a schematic view of a first structure of the receiving portion of the display panel shown in fig. 1 after the insulating layer is coated with the reflective coating. The receiving portion 122 is disposed at a boundary of the insulating layer 120 near the open window region 121. The first structure is a square wave-like structure, that is, the cross section of the accommodating part 122 in the direction perpendicular to the surrounding direction thereof is in a square wave shape. The square wave-shaped receiving portions 122 make the surface of the insulating layer 120 flatter and the light emitting elements 140 are more stable on the array substrate 110. As shown in fig. 4, the receiving portion 122 having a square wave shape in cross section can prevent the reflective paint from flowing toward the window 121, and prevent the reflective coating 130 from covering the area where the array substrate 110 and the light emitting element 140 are soldered.
Referring to fig. 5 and fig. 6 in conjunction with fig. 2, fig. 5 is a schematic view illustrating a second structure of the accommodating portion of the display panel shown in fig. 1 before the insulating layer is sprayed with the reflective coating. Fig. 6 is a second structural diagram of the accommodating portion of the display panel shown in fig. 1 after the insulating layer is sprayed with the reflective coating. The second configuration shown in fig. 5 and 6 differs from the first-like configuration in that the receiving portion 122 extends through the insulating layer 120 in a direction perpendicular to the insulating layer 120, so that a sufficient amount of reflective paint is received to prevent it from flowing toward the fenestration area 121. Of course, in some embodiments, the accommodating portion 122 may not penetrate the insulating layer 120 in a vertical direction of the insulating layer 120, as long as the reflective paint can be accommodated.
Referring to fig. 7 and 8 in conjunction with fig. 2, fig. 7 is a schematic view illustrating a third structure of the accommodating portion of the display panel shown in fig. 1 before the insulating layer is sprayed with the reflective coating. Fig. 8 is a third structural diagram of the accommodating portion of the display panel shown in fig. 1 after the insulating layer is sprayed with the reflective coating. The receiving portion 122 is disposed at a boundary of the insulating layer 120 near the open window region 121. The third structure is a saw-toothed shape, that is, the cross section of the accommodating portion 122 in a direction perpendicular to the circumferential direction thereof is saw-toothed. The serrated receiving portion 122 can insulate the region other than the window area 121 on the insulating layer 120, so that the area of the window area 121 is kept unchanged, and the precision of the window area 121 is improved. As shown in fig. 6, the receiving portion 122 with a saw-toothed cross section can also prevent the reflective coating from flowing to the window 121, and prevent the reflective coating 130 from covering the area where the array substrate 110 and the light emitting element 140 are welded.
Referring to fig. 9 and 10 in conjunction with fig. 2, fig. 9 is a schematic diagram illustrating a fourth structure of the accommodating portion of the display panel shown in fig. 1 before the insulating layer is sprayed with the reflective coating. Fig. 10 is a schematic view of a fourth structure of the receiving portion of the display panel shown in fig. 1 after the insulating layer is coated with the reflective coating. The receiving portion 122 is disposed at a boundary of the insulating layer 120 near the open window region 121. The fourth structure is wavy, that is, the cross section of the accommodating portion 122 in the direction perpendicular to the surrounding direction thereof is wavy. The wavy accommodation portion 122 makes the insulating layer 120 and the light reflecting coating 130 more fit, and the light reflecting coating 130 can cover more areas of the insulating layer 120 except the window area 121. As shown in fig. 10, the accommodating portion 122 with a wavy cross section can also prevent the reflective paint from flowing toward the window 121, and prevent the reflective coating 130 from covering the area where the array substrate 110 and the light emitting element 140 are welded.
In some embodiments, the receiving portion 122 may be a groove penetrating the insulating layer 120 in a circumferential direction thereof. The groove penetrates through the insulating layer 120 in the surrounding direction, the manufacturing process of the accommodating portion 122 is simple, and the groove can accommodate more reflective paint, so that the flow of the reflective paint to the windowing area 121 in the spray printing process is further prevented. In other embodiments, the receiving portion 122 may also be a receiving structure including a plurality of grooves. The plurality of grooves are discretely disposed around the fenestration area 121, surrounding the fenestration area 121. That is, a space is provided between adjacent grooves in the circumferential direction. This interval may enhance the fixing of the receiving region D, and thus may improve the soldering stability of the light emitting element 140 and the stability of the display device.
The application provides a display panel, including the insulating layer of array substrate and array substrate one side to and the insulating layer keeps away from the reflective coating of array substrate one side. Set up the portion of holding that can hold the reflection of light coating on the insulating layer in order to avoid the reflection of light coating to cover the windowing district that is used for electrical property contact light emitting component, improve light emitting component's welding stability, and then promoted display panel's stability, prolonged display panel's life, improved the production yields.
