Abstract
A method of dynamic frame presentation improvement for liquid crystal display is disclosed. The method comprises the step of providing a gray level mapping table, which maps the signal gray levels from 0 to N into mapped gray levels from 1 to N−1 level. Thereafter, the mapped data is fed into over-voltage compensation circuit. The over-voltage compensation circuit then implements process of the gray level ascending or gray level descending while the previous frame turns into current frame with a varied gray level.
