APPARATUS AND METHOD FOR CONTROLLING BACKLIGHT

摘要

An apparatus and a method for controlling backlight are provided. The apparatus for controlling backlight is adapted for driving a backlight module of a display panel, and the backlight module includes M luminance-controlling blocks, in which an i^th luminance-controlling block corresponds to an i^th luminance data. The apparatus for controlling backlight includes a calculation unit and a driving circuit. The calculation unit receives the i^th luminance data to output an i^th controlling data according to the proportion of the i^th luminance data and a maximum luminance data, in which M and i are natural numbers, and i<=M. The driving circuit receives the i^th controlling data to determine and drive the backlight luminance of the i^th luminance-controlling block.
