Title
(EN) COLOR CROSSTALK COMPENSATION FOR FLAT PANEL DISPLAYS
(FR) COMPENSATION DE DIAPHONIE DE COULEUR POUR DES ÉCRANS PLATS
Abstract
(EN) An example device for controlling a display includes a memory configured to store gray values of subpixels of a pixel and a display system communicatively coupled to the memory. The display system is configured to obtain a gray value for a first subpixel of the pixel from the memory and obtain a gray value for a second subpixel of the pixel from the memory. The display system is also configured to determine, based on the gray value for the second subpixel, an adjusted gray value for the first subpixel and output the adjusted gray value for the first subpixel.
(FR) L'invention concerne un dispositif donné à titre d'exemple pour commander une unité d'affichage, ledit dispositif comprenant une mémoire configurée pour stocker des valeurs de gris de sous-pixels d'un pixel et un système d'affichage couplé en communication à la mémoire. Le système d'affichage est configuré pour obtenir une valeur de gris pour un premier sous-pixel du pixel à partir de la mémoire et pour obtenir une valeur de gris pour un second sous-pixel du pixel à partir de la mémoire. Le système d'affichage est également configuré pour déterminer, sur la base de la valeur de gris pour le second sous-pixel, une valeur de gris ajustée pour le premier sous-pixel et pour délivrer en sortie la valeur de gris ajustée pour le premier sous-pixel.
