Abstract: A method for driving a liquid crystal display adjusts the falling edges of the gate driving signals for reducing image flicker. A first gate driving signal falls from a high level to a first level at the signal falling edge. A second gate driving signal falls from the high level to a second level at the signal falling edge. When the parasitic capacitance of a first pixel is larger than that of a second pixel, the first level is lower than the second level; when the parasitic capacitance of the first pixel is substantially the same as that of the second pixel, the first level is the same as the second level; when the parasitic capacitance of the first pixel is smaller than that of the second pixel, the first level is higher than the second level.

Abstract: A current regulator includes a first current source to provide a reference current varying with a dimming step, and a second current source to generate a drive current for a white LED according to the reference current. The reference current and the dimming step have a relationship identical to or approximating a relationship between luminance and lightness perceived by human eyes. Thus, the white LED is controlled to have a linear variation of the luminance perceived by human eyes when the dimming step is changed.
