Abstract
The color shift compensation method comprises: receiving target input gray scale data of a target sub pixel dot in a present line, and acquiring previous output gray scale data of a sub pixel dot of the previous line in the same display data line of the target sub pixel dot, and then, implementing digital to analog conversion to the target output gray scale data of the target sub pixel dot simultaneously corresponding to the target input gray scale data and the previous output gray scale data with combination of the target relationship table to acquire the target voltage of the target sub pixel dot, and ultimately, adjusting a color displayed by a target pixel where the target sub pixel dot is. With the present invention, the color shift issue due to the resistance difference of the fan section can be solved to promote the display effect.
