Abstract
A method for eliminating horizontal crosstalk and a system for adjusting a common electrode voltage are provided. The method for eliminating the horizontal crosstalk includes the followings. First brightness values of a first test image corresponding to different common electrode voltages, second brightness values of a second test image corresponding to different common electrode voltages, and flicker values of a third test image corresponding to different common electrode voltages are obtained respectively. A brightness difference between a corresponding first brightness value and a corresponding second brightness value is calculated and a first-difference common electrode voltage corresponding to a minimum difference is obtained. A second-difference common electrode voltage corresponding to a minimum flicker value is obtained. A mean of the first-difference common electrode voltage and the second-difference common electrode voltage is taken as a target common electrode voltage.
