Patent ID: 7564439

Claim:
A liquid crystal display (LCD), comprising: a pixel corresponding to a scan line and a data line and generating a predetermined brightness during a frame time; a data driving circuit for generating over driving pixel data according to pixel data of only a Nth frame, generating gray pixel data according to pixel data of a (N+1)th frame, and outputting driving voltages corresponding to the over driving pixel data, black pixel data and the gray pixel data to the pixel through the data line at a first time, a second time and a third time, respectively; and a scan driving circuit for outputting a scan signal to enable the pixel to receive the driving voltages corresponding to the over driving pixel data, the black pixel data and the gray pixel data through the scan line at the first time, the second time and the third time, respectively; wherein the driving voltages corresponding to the over driving pixel data, the black pixel data and the gray pixel data enable the pixel to generate a first brightness, a second brightness and a third brightness, respectively, and an equivalent brightness of the first brightness, the second brightness and the third brightness substantially equals to the predetermined brightness.
