摘要

The invention relates to a method and/or apparatus to improve the visual perception of an image displayed on a liquid crystal (LCD) panel, said method comprising steps for generating an adjusting signal (P_E,i+1) of a rear-lighting lamp of said panel depending on an target power value (P_T) and for generating a control signal (C_E,i+1) of the image contrast depending on said adjusting signal (P_E,i+1) of the rear-lighting lamp so as to increase/decrease the contrast of the displayed image when said adjusting signal (P_E,i+1) of the rear-lighting lamp decreases/increases.
