Abstract
A method and apparatus for driving a liquid crystal display enhances display quality and reduces power consumption. A portion of inputted data may be reproduced and used in the generation of dummy data. A scanning pulse is applied to gate lines of a liquid crystal display panel supporting lines crossing the gate lines. Consecutive ones of thin film transistors within columns of liquid crystal calls may be alternately coupled to adjacent ones of data lines. The inputted data and the dummy data are applied to the data lines in synchrony with the scanning pulse.
Claims28
A method of driving a liquid crystal display, comprising:
- generating dummy data by reproducing a portion of an inputted data;
- applying a scanning pulse to gate lines of a liquid crystal display panel comprising successively arranged data lines crossing the gate lines and thin film transistors arranged at the crossings of the data and gate lines, wherein consecutive ones of thin film transistors arranged within a column defined by at least one adjacent data line are alternately connected to the at least one adjacent data line;
- and
- applying the inputted data and the dummy data to the data lines of the liquid crystal display panel in synchrony with the scanning pulse.
A driving apparatus for a liquid crystal display, comprising:
- a dummy data generator for reproducing a portion of an inputted data and for generating dummy data;
- a liquid crystal display panel comprising successively arranged data lines crossing gate lines and thin film transistors arranged at the crossings of the data and gate lines, wherein consecutive ones of thin film transistors arranged within a column defined by at least one adjacent data line are alternately connected to the at least one adjacent data line;
- a gate driver for applying a scanning pulse to the gate lines;
- and
- a data driver for applying the inputted data and the dummy data to the data lines in synchrony with the scanning pulse.
