Abstract
In a liquid crystal display (LCD), a liquid crystal panel includes a plurality of subpixels. Source drivers drive source lines of the liquid crystal panel and gate drivers drive gate lines of the liquid crystal panel. A timing controller generates combination pixel data using current pixel data and previous pixel data, and supplies the generated combination pixel data to the source drivers. The previous pixel data is generated by delaying the current pixel data by a first time period.

A liquid crystal display (LCD) comprising:
- a liquid crystal panel including a plurality of subpixels;
- a plurality of source drivers, each of the plurality of source drivers being configured to drive a plurality of source lines of the liquid crystal panel;
- a plurality of gate drivers, each of the plurality of gate drivers being configured to drive a plurality of gate lines of the liquid crystal panel;
- and
- a timing controller configured to generate combination pixel data based on at least one of current pixel data and previous pixel data, the timing controller being further configured to supply the generated combination pixel data to the plurality of source drivers, the previous pixel data being generated by delaying the current pixel data by a time period.
A timing controller comprising:
- a buffer configured to generate (N×M)-bit current pixel data based on N-bit input pixel data;
- a delay device configured to generate (N×M)-bit previous pixel data by delaying the current pixel data by a first time period;
- a control signal generator configured to generate a source scan direction signal and a gate line number signal;
- and
- a data mapping unit configured to generate combination pixel data based on at least one of the current pixel data and the previous pixel data, the combination pixel data being generated according to the source scan direction signal and the gate line number signal.
A method of driving a liquid crystal panel comprising:
- generating combination pixel data based on at least one of current pixel data and previous pixel data, the previous pixel data being generated by delaying the current pixel data by a time period, the combination pixel data being generated according to a source scan direction and a gate line number;
- and
- driving the liquid crystal panel by supplying the generated combination pixel data to a source driver.
