Abstract
A method for solving feed-through effect, including steps of: obtaining desired gamma voltage value from a V-T curve (effective voltage-transmission curve) of the Liquid crystal and a gamma curve (gray scale-transmission curve); obtaining positive and negative frame feedback values by means of the desired gamma voltage value and the transistor reference data; adding the feedback values to obtain updating positive and negative frame gamma curve values; inputting the updating gamma curve values into the driving IC of the display; and through the feed-through effect, dropping the updating gamma curves back to the desired gamma curves, whereby the picture of the display will not flicker without adjusting Vcom DC bias.

A method for solving feed-through effect, comprising steps of:
- (1) obtaining desired gamma voltage values from a V-T curve (effective voltage-transmission curve) of a liquid crystal and a gamma curve (gray scale-transmission curve);
- (2) obtaining positive and negative frame feedback values by means of the desired gamma voltage value and the transistor reference data;
- (3) adding the feedback values to obtain updating positive and negative frame gamma curve values;
- (4) inputting the updating gamma curve values into the driving IC of the display;
- and
- (5) through the feed-through effect, dropping the updating gamma curves back to the desired gamma curves, whereby the picture of the display will not flicker without adjusting Vcom DC bias.
