Title
(EN) DISPLAY AND FILED-OF-VIEW ANGLE CONTROL DEVICE USED IN THE SAME

(JA) ディスプレイおよびそれに用いられる視野角制御装置
Abstract
(EN)
A display includes a field-of-view angle control liquid crystal panel (2) arranged at least one of the rear surface and the front surface of a display device so that the display can be applied to various use environments by switching the display state between a wide filed-of-view angle and a narrow field-of-view angle. The field-of-view angle control liquid crystal panel (2) includes: a liquid crystal cell (21) which hybrid-orientates a liquid crystal between orientation films (212a, 212b) arranged on a pair of light transmitting substrates, respectively; and a drive circuit for applying voltage to the liquid crystal layer of the liquid crystal cell (21). The liquid crystal cell (21) is arranged between two polarizing plates (13, 22) arranged so that the polarized transmission axes (X13, X22) intersect substantially orthogonally. The drive circuit switches the display state between the wide field-of-view angle and the narrow field-of-view angle by changing the orientation state of liquid crystal molecules (213p) of the liquid crystal layer of the field-of-view angle control liquid crystal panel (2).

L'invention concerne un affichage comportant un panneau à cristaux liquides de commande d'angle de champ de vision (2) disposé au moins au niveau de la surface arrière et de la surface avant d'un dispositif d'affichage, de sorte que l'affichage puisse s'appliquer à divers environnements d'utilisation en commutant l'état d'affichage entre un angle de champ de vision large et un angle de champ de vision réduit. Le panneau à cristaux liquides de commande d'angle de champ de vision (2) comporte : une cellule à cristaux liquides (21) orientant de façon hybride un cristal liquide entre des films d'orientation (212a, 212b) disposés sur une paire de substrats luminescents, respectivement ; et un circuit d'entraînement permettant d'appliquer une tension à la couche de cristaux liquides de la cellule à cristaux liquides (21). La cellule à cristaux liquides (21) est disposée entre deux plaques de polarisation (13, 22) disposées de sorte que les axes de transmission polarisés (X13, X22) se coupent sensiblement à angle droit. Le circuit d'entraînement commute l'état d'affichage entre l'angle de champ de vision large et l'angle de champ de vision réduit en modifiant l'état d'orientation des molécules de cristaux liquides (213p) de la couche de cristaux liquides du panneau à cristaux liquides de commande d'angle de champ de vision (2).

 表示状態を広視野角と狭視野角との間で切替えることにより様々な使用環境や用途に適応可能とするために、表示装置の背面および前面の少なくとも一方に視野角制御用液晶パネル(2)を備えたディスプレイである。視野角制御用液晶パネル(2)は、一対の透光性基板にそれぞれ設けられた配向膜(212a,212b)の間に液晶をハイブリッド配向させた液晶セル(21)と、液晶セル(21)の液晶層へ電圧を印加する駆動回路とを備えている。液晶セル(21)は、偏光透過軸(X13,X22)が略直交するよう配置された2枚の偏光板(13,22)の間に配置されている。前記駆動回路は、視野角制御用液晶パネル(2)の液晶層の液晶分子(213p)の配列状態を変化させることにより、表示状態を広視野角と狭視野角との間で切替える。
