Abstract

A method and apparatus for driving a liquid crystal display panel that is capable of driving a liquid crystal display panel having five color dots within one pixel. In the method, adjacent first color sub-pixels spaced at a desired distance, of a plurality of first color sub-pixels arranged at the middle portion of a pixel are shorted to apply a first color data to said adjacent first color sub-pixels. A second color data is applied to a plurality of second color sub-pixels arranged at one edge of said middle portion within said one pixel. A third color data is applied to a plurality of third color sub-pixels arranged at other edge of said middle portion within said one pixel.

Claims

1. A liquid crystal display device comprising:

a first pixel having first, second, third, fourth and fifth dot components, each of the first, second, third, fourth and fifth dot components having a switching element;

a second pixel having sixth, seventh, eighth, ninth and tenth dot components, each of the sixth, seventh, eighth, ninth and tenth dot components having a switch element;

a data driver and a gate driver;

a plurality of data lines connected to the data driver and respective switching elements;

a plurality of gate lines connected to the gate driver and the respective switching elements;

wherein the first and second dot components are connected to a first data line, the third dot component is connected to a second data line, and the fourth and fifth dot components are connected to a third data line,

wherein the sixth and seventh dot components are connected to a fourth data line, the eighth dot component is connected to a fifth data line, and the ninth and tenth dot components are connected to a sixth data line,

wherein the third dot component of the first pixel is connected to the eighth dot component of the second pixel,

wherein a first output line of the data driver is connected to first and second dot components, a second consecutive line of the data driver is disconnected from any dot components, a third consecutive line of the data driver is connected to fourth and fifth dot components, fourth consecutive line of the data driver is connected to the sixth and seventh dot components, fifth consecutive line of the data driver is connected to the eighth dot component, sixth consecutive line of the data driver is connected to the ninth and tenth dot components.
