Driving method for driver integrated circuit
View Patent ↗The present invention relates to a driving method for a driver IC, comprising: detecting a polarity of a gate line being driven; when the polarity changes, the driver integrated circuit drives the gate line with a first mode signal; when the polarity does not change, the driver integrated circuit drives the gate line with a second mode signal, a driving current of the first mode signal is greater than that of the second mode signal. In the present invention, the driver IC drives a gate line in different driving modes according to a condition that a polarity of the droved gate line changes. Since a driving current of the first mode signal is greater than that of the second mode signal, the present invention is enabled to minimize a difference between charging delays of pixel electrodes on gate lines, improving a dim line phenomenon.
