Problems solved by technology

[0003] However, since the exposure energy of the upper part of the isolation layer is greater than that of the bottom during exposure, the exposed opening pattern is very easy to form such as figure 1 Narrow top and wide bottom structure shown
In the subsequent inkjet printing process, due to the narrow top of the opening, the OLED light-emitting material is not easy to enter the opening, resulting in low production efficiency of the OLED light-emitting layer.

Abstract

The invention discloses an OLED display panel and a manufacturing method thereof. The OLED display panel comprises a substrate, an isolation layer and a plurality of pixel units, wherein the isolation layer and the pixel units are arranged on the substrate. The pixel units are separated by the isolation layer. The isolation layer is a negative light resistor and is provided with a plurality of openings formed by conducting exposure development on the isolation layer. The openings are used for containing light-emitting layers of the pixel units. A light-permeable light-enhancing layer is arranged between the part, around the openings, of the isolation layer and the substrate so that the light intensity of the side, close to the substrate, of the part, around the openings, of the isolation layer can be enhanced during exposure development and the openings with the tops wider than the bottoms can be obtained. In this way, the manufacturing efficiency of the OLED light-emitting layer can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED display panel and a manufacturing method thereof. Background technique [0002] At present, organic light-emitting diode (English: Organic Light-Emitting Diode, abbreviation: OLED) display panel has gradually become a mainstream force in the display field. In the existing manufacturing process of OLED display panel, inkjet printing technology is usually used to make the OLED light-emitting layer. Generally, an OLED display panel includes pixel units and a bank layer for separating the pixel units, and the bank layer is a negative photoresist. During the manufacturing process, an isolation layer is provided on the substrate, and the isolation layer is exposed to obtain a plurality of opening patterns, and OLED light-emitting materials are sprayed into the openings to form the light-emitting layer of the pixel unit. [0003] However, since the exposure energy o...
