Digital driving method for LCD panels

摘要

A liquid crystal display (LCD) with a driver IC and an LCD panel having source and gate lines. A gate driver is disposed in the LCD panel for sequentially supplying scan signals to the gate lines of the panel. A source driver in the driver IC converts pixel data into an analog source signal and supplies the signal to the source lines. A lookup table is stored with a mapping of possible luminance values for pixels of the LCD panel onto at least one luminance control parameter. The source driver converts the pixel data so that a voltage of the analog source signal increases during a gate scan period depending on the luminance control parameter in such a way that at the end of the gate scan period a voltage at a corresponding pixel electrode is equal to an analog value corresponding to the pixel data.
