Abstract

The invention discloses a display panel, a preparation method of the display panel and a display device. The display panel includes a gate layer; a gate insulating layer which is partially arranged on the gate layer; a first source and drain electrode layer which is arranged on the grid electrode layer and the grid electrode insulating layer; a first metal layer which is arranged on the first source and drain electrode layer; a first dielectric layer which is arranged on the first metal layer; and a second metal layer disposed on the first dielectric layer. Compared with the prior art, a second dielectric layer is not additionally arranged, so that the first metal layer is directly deposited on the thin film packaging layer, and meanwhile, the first metal layer is reserved in the terminal area, so that the problem of side etching of the first source and drain electrode layer in the terminal area can be solved; meanwhile, the second source and drain electrode layer in the terminal area is removed to reduce the height of the terminal area, so that the problem that short circuit possibly occurs in the terminal area is solved.

Description

technical field [0001] The invention relates to display panel technology, in particular to a display panel, a method for preparing the display panel and a display device. Background technique [0002] Display devices mainly include liquid crystal display (LCD for short), plasma display panel (PDP for short), organic light emitting diode (OLED for short), active matrix organic electroluminescence (Active Matrix organic light emitting diode, referred to as AMOLED), has a broad application space in vehicles, mobile phones, tablets, computers and TV products. [0003] OLED screens have the characteristics of thinness, high contrast, flexibility, and high transmittance, and have begun to become the mainstream screens of high-end smartphones. Technologies such as under-screen fingerprints, under-screen cameras, and under-screen sound have also been developed one after another. [0004] In recent years, a display device includes a touch sensing function for interacting with a user...
