Abstract
A method of controlling the brightness level of a screen display having a matrix of pixels that each have a brightness level controlled by a first and second voltage includes maintaining the first voltage of each pixel at a preselected voltage level. The second voltage level is controlled and adjusted depending on the ambient light conditions. The second voltage is increased during daytime conditions to increase the brightness of the screen display and decreased during nighttime conditions to decrease the brightness of the display. The ambient light conditions are determined by using a light-sensitive sensor or a manually adjustable control.
