Abstract
(EN)
The present invention provides a display panel driving method. The display panel driving method comprises: performing brightness value compensation only when it is determined that an xth frame of display picture is an overloaded picture, and not performing brightness value compensation when it is determined that the xth frame of display picture is a non-overloaded picture. The present invention avoids a change in the display of the non-overloaded picture caused by miscompensation of the non-overloaded picture, improving the accuracy of compensation.

La présente invention concerne un procédé d'entraînement de panneau d'affichage. Le procédé d'entraînement de panneau d'affichage consiste à : réaliser une compensation de valeur de luminosité uniquement lorsqu'il est déterminé qu'une xème trame d'image d'affichage est une image surchargée, et ne pas réaliser de compensation de valeur de luminosité lorsqu'il est déterminé que la xème trame d'image d'affichage est une image non surchargée. La présente invention évite un changement dans l'affichage de l'image non surchargée provoqué par une mauvaise compensation de l'image non surchargée, ce qui améliore la précision de compensation.

本发明提供一种显示面板驱动方法。该显示面板驱动方法,通过判断第x帧显示画面为重载画面时才进行亮度值补偿,判断第x帧显示画面为非重载画面时不进行亮度值补偿,防止对非重载画面进行误补偿而改变非重载画面的显示,提高补偿的准确性。
