ABSTRACT:
A driving method for LCD panels is disclosed, wherein the driver circuit includes multiple data line drivers and at least two gate line drivers, and the first gate line driver produces a normal image with sequential line scanning starting from the beginning of a frame, and the second gate line driver produces a dimmed image starting from a predetermined number of lines below at the same time to emulate one full sweep across a CRT. Therefore, a dimmed image is inserted into every digitized image, where a dimmed image is defined to be a digitized image with each pixel having a fraction 1/N of the original pixel value. The LCD panel drive using this driving method achieves performance closer to the impulse approach used in CRT displays, and the flickering phenomenon can be significantly rectified.
