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.
(FR) 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.
(ZH) 一种偏振光学组件、OLED器件及制备方法、显示装置。偏振光学组件(7)包括:胆甾相液晶层(8)、λ/4波片(6)和线偏振片(5),λ/4波片(6)位于胆甾相液晶层(8)和线偏振片(5)之间,λ/4波片(6)的快轴或者慢轴与线偏振片(5)的透光轴存在夹角,且外界光依次经过线偏振片(5)、λ/4波片(6)后形成的偏振光可透过胆甾相液晶层(8)。该显示装置能够在减少外界光反射的前提下,增大出光量。
