Abstract
An LCD (Liquid Crystal Display) Device of improvement of flicker upon switching frame rate and method for the same are proposed. The LCD device includes a pixel matrix, a timing controller and a gate driver. The timing controller outputs a first Gate-On-Enable signal to the gate driver, when the LCD device displays frame according to a first frame rate. When the first frame rate is switched to a second frame rate, the timing controller outputs a second Gate-On-Enable signal to the gate driver to cause a charge time of the pixel matrix to be unchanged. It is appreciated that a pulse width of the second Gate-On-Enable signal is equal to a summation of a pulse width of the first Gate-On-Enable signal and an adjusted pulse width.
