Title (EN) POLARIZATION DEVICE AND DISPLAY
(FR) DISPOSITIF DE POLARISATION ET AFFICHEUR
(ZH) 偏光装置及显示器
Abstract:
(EN) A polarization device (100) and a display (200) having the polarization device (100). The polarization device (100) comprises a first polarizer (10), a second polarizer (20) and a compensation film (30) arranged between the first polarizer (10) and the second polarizer (20). An absorption axis of the first polarizer (10) is perpendicular to an absorption axis of the second polarizer (20). A slow axis of the compensation film (30) is perpendicular to the absorption axis of the first polarizer (10) or the absorption axis of the second polarizer (20). The polarization device (100) and the display (200) eliminate the phenomenon of light leakage caused by non-orthogonality of the polarizers (10, 20) in the side-looking process by means of the compensation film (30), and therefore, the display effect can be improved, and the display quality is improved.
(FR) La présente invention a trait à un dispositif de polarisation (100), et à un afficheur (200) comportant le dispositif de polarisation (100). Ce dispositif de polarisation (100) comprend un premier polariseur (10), un second polariseur (20), ainsi qu'un film de compensation (30) disposé entre le premier polariseur (10) et le second polariseur (20). L'axe d'absorption de ce premier polariseur (10) est perpendiculaire à l'axe d'absorption dudit second polariseur (20). L'axe lent du film de compensation (30) est perpendiculaire à l'axe d'absorption dudit premier polariseur (10) ou à l'axe d'absorption dudit second polariseur (20). Le dispositif de polarisation (100) et l'afficheur (200) suppriment le phénomène de fuite de lumière provoqué par la non-orthogonalité des polariseurs (10, 20) lors du processus de balayage latéral au moyen du film de compensation (30), et, par conséquent, l'effet d'affichage peut être amélioré, et la qualité d'affichage est meilleure.
(ZH) 一种偏光装置(100)及具有所述偏光装置(100)的显示器(200),其中偏光装置(100)包括第一偏光片(10)、第二偏光片(20)以及设置于所述第一偏光片(10)以及所述第二偏光片(20)之间的补偿膜(30)。所述第一偏光片(10)与所述第二偏光片(20)的吸收轴垂直,所述补偿膜(30)的慢轴垂直所述第一偏光片(10)的吸收轴或者所述第二偏光片(20)的吸收轴。所述偏光装置(100)和显示器(200)通过所述补偿膜(30)消除侧视时因偏光片(10,20)非正交所产生的漏光现象,因此能够改善显示效果,提升显示品质。
