摘要： In a method of driving a display device and a driving circuit using the driving method, when a current needed to display an image corresponding to one frame is calculated based on a data signal, a second vertical start signal delayed by a first time interval more than a first vertical start signal based on the calculated current. A first gate signal is sequentially output in response to the first vertical start signal, and a display data voltage obtained from the data signal is output during a high period of the first gate signal. A second gate signal is sequentially output in response to the second vertical start signal, and a black data voltage is output during a high period of a second gate signal. Thus, the current applied to a display part is controlled, thereby reducing power consumption and improving moving image.

摘要： A display device and a driving method thereof are provided. The display device includes a plurality of pixels that displays a first color, a second color, a third color, and a white color; a signal processor that generates a white color output image signal based on three input image signals displaying the first to third colors, generates a white color temperature correcting constant based on the white color output image signal, and generates first color, second color, and third color output image signals that correct the first color, second color, and third color input image signals based on the white color temperature correcting constant; and a data driver that converts the output image signal to a data voltage and supplies the data voltage to the pixel to allow the pixel to display an image. Therefore, a color temperature of white light that four color pixels emit can be adjusted to a target color temperature by adjusting an image signal value related to the remaining three color pixels according to luminance of white light that a white pixel emits.
