Title:
BRIGHTNESS ENHANCEMENT FILM FOR QUANTUM DOT DISPLAY PANEL AND LENS ARRAY
Document Type and Number:
WIPO Patent Application WO/2021/088113
Kind Code:
A1
Abstract:
A quantum dot display panel and a manufacturing method therefor. The quantum dot display panel comprises a pixel layer (100) having a retaining wall (110) and quantum dots, a lens layer (200) having a lens array (210), and a brightness enhancement film (300) having a prism array (310). When the ambient light (700) enters the quantum dot display panel, the ambient light (700) is converged and collimated by the brightness enhancement film (300); then, the lens array (210) converges the ambient light (700) to a plurality of retaining walls (110) having light absorption characteristics. The lens array (210) maintains the contrast of the quantum dot display panel, and the brightness enhancement film (300) enhances the wide-viewing-angle display effect of the quantum dot display panel.
