Embodiment 1
[0033] see figure 1 , figure 1 A schematic cross-sectional view of the display panel provided in this embodiment, the present invention provides a display panel, including a base layer 10, a flat layer 20, a pixel definition layer 30, a light emitting layer 40, a pixel electrode layer 50 and a thin film encapsulation layer 60 arranged in sequence .
[0034] The display panel is provided with a via hole 70, and the via hole 70 penetrates downward through the pixel electrode layer 50, the light emitting layer 40, the pixel definition layer 30 and the flat layer 20 until the surface of the base layer 10, which is equivalent to removing the flat layer 20, the pixel The definition layer 30 , the light emitting layer 40 and the pixel electrode layer 50 , and the removed part is filled with the filling layer 80 .
[0035] The filling material used in the filling layer 80 is an organic material, and its light transmittance is greater than 90%. Hexamethylsilyl ether or epoxy resin ca...
Embodiment 2
[0041] This embodiment provides the preparation method of the display panel described in Embodiment 1, which includes the following steps:
[0042] Step S1 : Fabricate the base layer 10 and the flat layer 20 , the pixel definition layer 30 , the light emitting layer 40 and the pixel electrode layer 50 disposed thereon.
[0043] Step S2: forming a via hole 70 on the flat layer 20, the pixel definition layer 30, the light emitting layer 40 and the pixel electrode layer 50 disposed on the base layer 10;
[0044] see figure 2 , figure 2 Shown is a schematic cross-sectional view of the display panel in step S2 provided in this embodiment; in other implementation manners, the via hole 70 can also be made by laser, which is not limited here and can be determined as needed.
[0045] Step S3: filling material into the via hole 70 to form a filling layer 80;
[0046] see image 3 , image 3Shown is a schematic cross-sectional view of the display panel in step S3 provided by the e...
Embodiment 3
[0055] This embodiment provides a display device, which includes a body on which the display panel according to the present invention is arranged, wherein the body is also provided with electronic components, and the electronic components are arranged on the display panel. The corresponding lower position of the via hole.
[0056] Compared with the prior art, the beneficial effect of the present invention is that: the present invention provides a display panel and its preparation method. A via hole is arranged on the display panel, and a high light-transmitting material is filled into the via hole so that its surface protrudes to form a lens. The structure plays the role of converging light, so that the camera under the screen has a wider viewing angle and improves the imaging quality; and the original wiring layer and film packaging layer are retained to maximize the water and oxygen barrier function of the via area.
