Abstract
(EN)
A polarising optical component, an OLED device and a preparation method therefor, and a display device. The polarising optical component (7) comprises: a cholesteric phase liquid crystal layer (8), a λ/4 wave plate (6) and a linear polariser (5), wherein the λ/4 wave plate (6) is located between the cholesteric phase liquid crystal layer (8) and the linear polariser (5), there is an included angle between a fast axis or a slow axis of the λ/4 wave plate (6) and a light-transmitting axis of the linear polariser (5), and polarised light formed after external light passes through the linear polariser (5) and the λ/4 wave plate (6) can transmit through the cholesteric phase liquid crystal layer (8). The display apparatus can increase the quantity of emergent light with the premise of reducing external reflected light.

La présente invention concerne un composant optique de polarisation, un dispositif DELO et son procédé de fabrication, et un dispositif d'affichage. Le composant optique de polarisation (7) est pourvu : d'une couche de cristaux liquides à phase cholestérique (8), d'une lame-onde λ/4 (6) et d'un polariseur linéaire (5), la lame-onde λ/4 (6) étant située entre la couche de cristaux liquides à phase cholestérique (8) et le polariseur linéaire (5), un angle inclus étant situé entre un axe rapide ou lent de la lame-onde λ/4 (6) et un axe de transmission de lumière du polariseur linéaire (5), et la lumière polarisée formée après le passage de la lumière externe à travers le polariseur linéaire (5) et la lame-onde λ/4 (6) pouvant émettre à travers la couche de cristaux liquides à phase cholestérique (8). L'appareil d'affichage permet d'augmenter la quantité de lumière émergente sur le principe de réduire la lumière réfléchie externe.
