Problems solved by technology

However, due to technical limitations, hidden under-screen camera technology is still blank
For OLED display panels, top-emitting devices are mainly used. The technical difficulty in realizing a hidden camera is that the cathode layer in the camera area will reflect light to the camera, thus affecting the photo effect

Embodiment Construction

[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0044] Please refer to figure 1As shown, a display panel 1 is provided in this embodiment. The display panel 1 is an OLED display panel 1 of a top-emitting device, which can realize the technology of a hidden under-screen camera. The display panel 1 has a display area 101 and a camera area 102 located in the display area 101 . Wherein, the camera area 102 can realize normal display, that is to say, the camera area 102 can be hidden in the display area 101 when it is displayed ...

Abstract

The invention provides a display panel and a preparation method thereof. The display panel is provided with a display area and a camera shooting area, and the display panel comprises a base layer, a light emitting layer and a cathode layer. The cathode layer comprises a display area cathode layer and an image pickup area cathode layer, and the image pickup area cathode layer is of a net structure and partially covers an image pickup area. According to the display panel, under the condition that normal display of the image pickup area is guaranteed, the light transmittance of the image pickup area can be improved, the cathode light reflection effect of the image pickup area is reduced, and therefore a photographing effect is improved.

Description

technical field [0001] The present application relates to the technical field of display devices, in particular to a display panel and a manufacturing method thereof. Background technique [0002] In the field of display devices, there are currently several different styles of screen forms, namely: Infinity-U (water drop screen), Infinity-V (V-shaped groove), Infinity-O (screen punching) and New-Infinity forms. The form of New-Infinity is hidden under-screen camera technology. However, due to technical limitations, hidden under-screen camera technology is still blank. For OLED display panels, top-emitting devices are mainly used. The technical difficulty in realizing a hidden camera is that the cathode layer in the camera area will reflect light to the camera, thereby affecting the photo effect. [0003] Therefore, in the case of ensuring the normal display of the imaging area, improving the light transmittance of the imaging area becomes a technical focus. Contents of t...
