Abstract:
(EN) A display device viewing angle compensation calculation method, a viewing angle compensation structure and a display device. The method comprises: measuring a tristimulus value of all the grayscale display red, green, and blue of the display device in a viewing angle and a brightness gamma curve; calculating a center viewing angle (θC), a first viewing angle (θL) and a second viewing angle (θR)of observation viewing angles of the display device to obtain the viewing angle range of the observation viewing angles; obtaining a display look-up table by means of the degrees of the viewing angle and the brightness gamma curve according to a viewing angle algorithm; obtaining a compensation value of the viewing angle by means of the center viewing angle and the viewing angle range according to the display look-up table; and finally adjusting the corresponding tristimulus value in the display device according to the compensation value of the viewing angle.
(FR) Procédé de calcul de compensation d'angle de visée de dispositif d'affichage, structure de compensation d'angle de visée et dispositif d'affichage. Le procédé comprend les étapes qui consistent : à mesurer la composante trichromatique de l'ensemble du rouge, du vert et du bleu de l'affichage en niveaux de gris du dispositif d'affichage dans un angle de visée et une courbe des gammas de la luminosité; à calculer un angle de visée central (θC), un premier angle de visée (θL) et un second angle de visée (θR) d'angles de visée d'observation du dispositif d'affichage pour obtenir la fourchette d'angles de visée des angles de visée d'observation; à obtenir une table de consultation d'affichage au moyen des degrés de l'angle de visée et de la courbe des gammas de la luminosité selon un algorithme d'angle de visée; à obtenir une valeur de compensation de l'angle de visée au moyen de l'angle de visée central et de la fourchette d'angles de visée conformément à la table de consultation d'affichage; et à ajuster la composante trichromatique correspondante dans le dispositif d'affichage en fonction de la valeur de compensation de l'angle de visée.
(ZH) 一种显示装置视角补偿计算的方法、视角补偿结构及显示装置,透过量测显示装置于视角中所有灰阶显示红色、绿色及蓝色的三色刺激值,以及亮度伽马曲线;以及计算显示装置观测视角的中心视角(θC)、第一视角(θL)以及第二视角(θR),取得观测视角的视角范围;并透过视角的角度以及亮度伽马曲线,依据视角算法取得显示查找表;再通过中心视角以及视角范围,依据显示查找表,取得视角补偿值;最后依据视角补偿值,调整显示装置中对应的三色刺激值。
