Abstract

The invention provides a display panel and a preparation method thereof, and the display panel forms an organic light-emitting structure layer and a packaging structure layer on a pixel definition layer, and the organic light-emitting structure layer and the packaging structure layer wrap the whole surface of a through hole. According to the invention, the through hole is firstly formed, and thenthe surface of the through hole is coated with the organic light-emitting structure layer and the packaging structure layer, so that the packaging structure layer coats the peripheral side of the through hole, and water vapor is prevented from corroding a metal layer of a display area along the gap between the film layers of the cross section of an open hole.

Description

technical field [0001] The present application relates to a display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] In an existing OLED device, in order to install a camera, a hole needs to be opened on the OLED panel to expose the camera. [0003] However, in the existing process, the step of opening holes is after the organic light-emitting diode panel structure film layer is fabricated. This will cause the water vapor in the atmospheric environment to erode inwardly the metal layer and the organic light-emitting layer of the display area along the gap between the film layers of the opening section, shortening the life of the organic light-emitting diode panel. Contents of the invention [0004] The embodiment of the present application provides a display panel and its preparation method to solve the problem that in the existing organic light emitting diode panel, water vapor easily erodes the metal layer an...
