Abstract
(EN)
A pixel signal conversion method and device, and a computer device, said method comprising: according to a first initial sub-pixel signal, a second initial sub-pixel signal and a third initial sub-pixel signal in the pixel signals, obtaining first stimulus value signals, second stimulus value signals and third stimulus value signals correspondingly. When the converted pixel signals are applied to a mixed color display composed of four sub-pixels of W, R, G, and B, the display effect is closer to the actual performance of the original R, G, and B mixed color, and the color cast defect of the large viewing angle is reduced.
(FR)
Procédé et dispositif de conversion de signal de pixel, et dispositif informatique, ledit procédé consistant à : selon un premier signal de sous-pixel initial, un deuxième signal de sous-pixel initial et un troisième signal de sous-pixel initial dans les signaux de pixel, obtenir des premiers signaux de valeur de stimulus, des deuxièmes signaux de valeur de stimulus et des troisièmes signaux de valeur de stimulus de façon correspondante. Lorsque les signaux de pixel convertis sont appliqués à une unité d'affichage couleur mixte composé de quatre sous-pixels de W, R, G et B, l'effet d'affichage est plus proche des performances réelles de la couleur mélangée R, G et B d'origine, et le défaut de dominante de couleur du grand angle de vision est réduit.
