Method for controlling luminance of backlight unit
First Claim
1. A method for controlling luminance of an edge type backlight unit having a plurality of lamps at opposite sides of a light-guiding plate, the method comprising:
- analyzing luminance data for each frame of an image before outputting the image;
selecting a luminance level from a Look-Up Table LUT that classifies luminance according to the analyzed luminance data;
outputting lamp on/off control signals according to the selected luminance level; and
providing lamp on/off signals to respective lamps according to the lamp on/off control signals.
