Method of driving a display panel, display panel driving apparatus for performing the method and display apparatus having the display panel driving apparatus

摘要

A display panel driving apparatus includes an image pattern analyzing part, a clock signal generating part and a data driving part. The image pattern analyzing part is configured to analyze an image pattern of an image data. The clock signal generating part is configured to generating a clock signal having a different pulse width according to the image pattern of an image data. The data driving part is configured to drive a data line of a display panel in response to the clock signal. Thus, power consumption and heating of the data driving part may be decreased.

1. A method of driving a display panel, comprising: analyzing an image pattern of an image data;
Generating a clock signal having a different pulse width according to the image pattern of an image data, the clock signal controlling a pre-charge time of a data line; and outputting the clock signal to a data driving part, wherein the clock signal has a first clock signal having a first pulse width and a second clock signal having a second pulse width wider than the first pulse width, and wherein the first pulse width and the second pulse width are greater than zero, and wherein the generating a clock signal having different pulse width comprises: generating a first pulse width of the clock signal when the image pattern is a black image or a white image; and generating a second pulse width greater than the first pulse width of the clock signal when the image pattern is a stripe pattern of black alternating with white.
