Abstract
A method for driving an image display device having a backlight lamp and a display screen includes receiving an image data signal; and based the image data signal, calculating a content-related backlight control signal for the backlight lamp for setting the intensity of the backlight. The method further includes generating an average signal that represents a time-average of the power consumed by the backlight lamp; comparing the average signal with a reference signal; and based on the calculated content-related backlight control signal and taking into account the result of the comparison, generating an actual backlight control signal for the backlight lamp.
