摘要： A display device includes a first unit pixel disposed in a first pixel column and a first pixel row, and a second unit pixel disposed in the first pixel column and a second pixel row adjacent to the first pixel row, and first and second gate lines extending in a row direction and having gate voltage input pads at a terminal portion thereof. First and second data lines extend in a column direction and are connected to the first unit pixel and the second unit pixel, respectively. A first charge control line extends in the row direction and has a charge control gate voltage input pad disposed at a terminal portion thereof. The first gate line is connected to the first unit pixel and the second gate line is connected to the second unit pixel. The first gate line and the second gate line simultaneously receive a same gate pulse.

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.
