Abstract
In a liquid crystal display or panel and a method of driving the same, in response to the receipt of a plurality of image control signals each intended for one of the data lines, the image control signals are modified in accordance with different characteristics of the data lines. The modified image control signals are outputted to the respective data lines to drive the liquid crystal display or panel.
Claims20
A method of driving a liquid crystal panel in response to a plurality of image control signals being transmitted to a plurality of pixels in said liquid crystal panel via a plurality of source driver units and a plurality of data lines respectively connected with the source driver units, said method comprising the steps of:
- providing a white-tracking code;
- applying a plurality of different first weights to said white-tracking code to obtain a plurality of weighted white-tracking codes, each of said first weights being associated with one of the data lines;
- providing an over-driving value;
- applying a plurality of different second weights to said over-driving value to obtain a plurality of weighted over-driving values, each of said second weights being associated with one of the data lines;
- and
- for each of said data lines, selecting and outputting one of said weighted white-tracking codes and one of said weighted over-driving values to the corresponding source driver unit to adjust said image control signals inputted to the pixels associated with said data line.
A liquid crystal display comprising:
- a liquid crystal panel having a plurality of data lines and a plurality of corresponding pixels;
- a plurality of source driver units coupled to said data lines, respectively;
- and
- an image processor coupled to said source driver units for receiving a plurality of image control signals,
- modifying the image control signals in accordance with different characteristics of said data lines, and
- outputting said modified image control signals to said source driver units, respectively.
A method of driving a liquid crystal display, said liquid crystal display comprising a plurality of source driver units and a plurality of data lines connected therewith, said method comprising the steps of:
- receiving a plurality of image control signals each intended for one of the data lines;
- modifying said image control signals to obtain a plurality of modified image control signals in accordance with different characteristics of said data lines;
- and
- outputting said modified image control signals to the respective data lines to drive said liquid crystal display.
