Abstract
A method of dark frame insertion for improving a display device is disclosed. The method includes receiving a gray level data stream, generating a first brightness data stream according to a first gamma curve, generating a second brightness data stream according to a second gamma curve, sequentially inserting the second brightness data stream into the first brightness data stream for generating a third brightness data stream, and providing the third brightness data stream to the display device for display.
Claims21
A method for generating a frame stream to be displayed on a display device comprising:
- (a) receiving a gray level data stream;
- (b) generating a first brightness data stream according to the gray level data stream and a first gray level to brightness transformation;
- (c) generating a second brightness data stream according to the gray level data stream and a second gray level to brightness transformation;
- and
- (d) forming the frame stream by making the first brightness data stream interlaced with the second brightness data stream;
- wherein the first gray level to brightness transformation and the second gray level to brightness transformation make at least part of the gray level data stream correspond to non-zero brightness.
