Abstract

The invention provides a display panel and a preparation method thereof. The display panel comprises a substrate, a packaging layer, a black matrix layer and an oleophobic layer, the packaging layer is arranged on the surface of the substrate, the black matrix layer is arranged on the packaging layer, the black matrix layer comprises through holes, the through holes penetrate through the black matrix layer to expose the packaging layer, and the oleophobic layer covers the black matrix layer. According to the application, the oleophobic layer is arranged on the black matrix layer, so that the contact angle between the photoresist liquid drop and the interface of the through hole is increased, and the ink effectively flows into the through hole and forms a film uniformly in the printing process.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Due to the low transmittance, large thickness, brittle texture and high price of the polarizer itself, the application of flexible OLED display technology is greatly limited. Therefore, a method of manufacturing color filters instead of circular polarizers on thin film packaging is proposed. However, inkjet printing technology is usually used to prepare color filters on packaging films. The color filters prepared by inkjet printing technology have a simple process, no photolithography mask is needed in the production process, and the material utilization rate is high. When the photoresist droplets are printed into the pixel pits, the contact angle between the ink and the black matrix layer is too small, so that the printing cannot be performed. Contents of the invention [0003] The p...
