Digital driving method for lcd panels

A method for driving a liquid crystal display comprising:

• sequentially supplying, by a gate driver, scan signals to gate lines of a liquid crystal display panel;
• converting, by a source driver, inputted pixel data into analog source signals and outputting the signals to source lines of the liquid crystal display panel;
• storing, in a lookup table, a mapping of possible luminance values for pixels of said liquid crystal display panel onto at least one luminance control parameter (α, Δ);
• and
• converting said inputted pixel data so that a voltage V(t) of said analog source signal increases during a gate scan period depending on said at least one luminance control parameter (α, Δ), and that at the end of said gate scan period, a voltage at a corresponding pixel electrode is equal to an analogue value corresponding to said inputted pixel data.

A liquid crystal display module having no digital-to-analog converter, said module comprising:

• a liquid crystal display panel;
• and
• a driver circuit coupled to said panel, wherein
• said panel has gate lines and a source lines, at lease one of said gate lines providing a scan signal and at least one of said source lines providing an analog source signal, and a gate driver for sequentially providing the scan signal to one of the gate lines, and wherein
• said driver circuit has a source driver for converting pixel data into said analog source signal and providing said analog source signal to one of said source lines.

A method for driving a display module, comprising:

• converting pixel data into an analog source signal;
• sequentially providing a scan signal to said display module;
• and
• providing said analog source signal to said display module.
