Abstract

The invention provides a method for preparing a pixel defining layer, a display panel and a manufacturing method thereof, which solves the problem in the prior art that water molecules penetrating into a display device pass through the pixel defining layer laterally. The display panel includes a substrate and an organic light emitting diode structural unit layer on the substrate. The organic light emitting diode structural unit layer includes: a plurality of organic light emitting diode structural units arranged at intervals; and pixel boundaries between the plurality of organic light emitting diode structural units layer, the pixel-defining layer includes a hydrophobic isolation zone that blocks the passage of water molecules.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a preparation method of a pixel defining layer, a display panel and a preparation method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) display panel has become a new generation of display technology with broad development prospects due to its many excellent characteristics, such as light and thin, flexible, wide viewing angle, fast response speed, and high luminous efficiency. [0003] However, since the OLED display panel is extremely sensitive to water vapor and oxygen in the environment, once water vapor or oxygen penetrates into the OLED display panel, it will easily lead to the failure of the organic light-emitting material, which becomes an important factor affecting the life of the OLED display panel. one of the reasons. Contents of the invention [0004] In view of this, the embodiments of the present invention are dedicated to providing a...
