Abstract
A display device dynamically determines a duration of the illumination period for a display frame to adjust an average brightness of a display device as the framerate dynamically changes. The display device includes a backlight unit (BLU) for providing light for displaying an image, a plurality of pixels for modulating the light provided by the BLU, and a controller circuit for controlling the BLU. The controller circuit measure a duration of a previous frame and determine a duration for an illumination period of a current frame based on the measured duration of the previous frame. The control circuit then controls the BLU based on the determined duration of the illumination period for the current frame.
