Title:
OPTICAL THIN FILM, ORGANIC ELECTROLUMINESCENT DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/051988
Kind Code:
A1
Abstract:
Disclosed is an optical thin film (5), comprising a transparent thin film body (1), wherein one side surface of the thin film body (1) is provided with several grooves (3), and a protrusion (2) is formed between adjacent grooves (3). Disclosed is an organic electroluminescent display panel, comprising an organic electroluminescent device and a packaging layer (42) arranged on the organic electroluminescent device, and further comprising the optical thin film (5), wherein the optical thin film (5) is arranged on a side surface, away from the organic electroluminescent device, of the packaging layer (42), and the grooves (3) are arranged opposite a light-emitting area of the organic electroluminescent device. Disclosed is a method for manufacturing an organic electroluminescent display panel. The grooves (3) are arranged on the thin film body (1), and an existing polarizer is replaced with the optical thin film, so that natural light is projected into the grooves (3) and is then annihilated due to the light loss caused by multiple reflections, thus reducing the loss of light emitted by an organic electroluminescent device itself, while also reducing the influence of natural light on the organic electroluminescent device, and further reducing the production costs.
