Title
(EN) VR DISPLAY COMPENSATION METHOD AND COMPENSATION DEVICE, AND DISPLAY DEVICE

Abstract
(EN) A VR display compensation method and compensation device, and a display device. The VR display compensation method comprises: calculating, according to the rendering resolution, rendering frame frequency and bandwidth data of a display panel, a first synchronous signal value to be outputted by a controller (S11); comparing the first synchronous signal value with a pre-stored second synchronous signal value of the display panel (S12); if the first synchronous signal value is compared to be greater than the second synchronous signal value, generating compensated image data between original image data of two adjacent frames (S13); and according to the generated compensated image data, compensating an image to be displayed (S14).
(FR) L'invention concerne un dispositif de compensation et un procédé de compensation d'affichage de RV, ainsi qu'un dispositif d'affichage. Le procédé de compensation d'affichage de RV consiste à : calculer, selon la résolution de rendu, des données de fréquence de trame et de bande passante de rendu d'un panneau d'affichage, une première valeur de signal synchrone devant être délivrée par un dispositif de commande (S11) ; comparer la première valeur de signal synchrone à une seconde valeur de signal synchrone pré-stockée du panneau d'affichage (S12) ; si, lors de la comparaison, la première valeur de signal synchrone est supérieure à la seconde valeur de signal synchrone, générer des données d'image compensées entre des données d'image d'origine de deux trames adjacentes (S13) ; et selon les données d'image compensées générées, compenser une image à afficher (S14).
(ZH) 一种VR显示的补偿方法及补偿装置和一种显示装置,该VR显示的补偿方法包括:根据显示面板的渲染分辨率、渲染帧频和带宽数据,计算出要由控制器输出的第一同步信号值(S11);将第一同步信号值与预先存储的显示面板的第二同步信号值进行比较(S12);当比较出第一同步信号值大于第二同步信号值时,生成两相邻帧原始图像数据之间的补偿图像数据(S13);以及根据所生成的补偿图像数据,对待显示的图像进行补偿(S14)。
