Benefits of technology

The invention provides an improved method for creating layers on organic light-emitting devices (OLEDS). By adding specific materials like SiON2 instead of traditional fluoropolymers used during manufacturing processes, this process allows for better control over curing temperatures without affecting their effectiveness at lower temperatures. This results in more reliable display with fewer defects caused by poor quality components such as metal lines.

Problems solved by technology

This technical problem addressed in this patents relates to improving the quality control during manufacturing processes for making electronic displays with these types of display elements that have improved brightness levels over time without losing their functionality.

Abstract

The invention discloses a manufacturing method of a display panel. The manufacturing method comprises the following steps: forming a thin film transistor layer on a substrate; forming a flat layer onthe side of the thin film transistor layer away from the substrate, wherein the material of the flat layer is siloxane; placing a mask plate at the position at a certain distance from the flat layer,performing ultraviolet irradiation on the local area of the flat layer through the mask plate and oxidizing the flat layer located in the local area; and performing dry etching on the flat layer to remove the oxidized flat layer located in the local area and enabling the thin film transistor layer to be exposed in the local area. The temperature is not higher than 200 DEG C in case of curing the flat layer, which will not cause sharp reduction of the performance of TFT devices or even failure, thus improving the reliability of OLED.
