A display device includes a first pixel connected to a first gate line and a data line, a second pixel connected to a second gate line, different from the first gate line, and the data line, the second pixel being pre-charged when the first pixel is charged, a compensation LUT which stores LUT values for compensating a charging rate during a main charging of the second pixel; and an image signal processor which generates a compensated image signal for the main charging of the second pixel. The image signal processor may include a correction value calculating unit which calculates a correction value from the compensation LUT based on first and second input image signal of respective first and second pixels, and a compensated value generating unit which generates a compensated image signal for the second pixel based on the correction value and the second input image signal.

Display device and image signal compensating method

A display device includes: a display panel displaying a still image and a motion picture; a display panel which displays a still image and a motion picture; a signal controller which controls signals to drive the display panel; and a graphics processing unit which transmits input image data to the signal controller, where the signal controller includes a frame memory which stores compressed image data generated by compressing the input image data, and a mixer which mixes compression recovered image data generated by recovering the compressed image data and the input image data to generate mixed image data.

Display device and driving method thereof

A display device includes: a display panel configured to display an image; and a signal controller configured to control signals to drive the display panel. The signal controller includes: an image data converter configured to convert image data of 'm' bits into image data of 'n' bits; a gray voltage generator configured to generate a gray voltage corresponding to the image data of &#x201c;n&#x201d; bits; a control signal generator configured to generate a gate control signal; and a luminance change controller configured to control a luminance change period of an image displayed via the display panel to be greater than or equal to one second.

Display device

A display device includes a display panel including a plurality of pixels, a data driver which transmits data voltages to the plurality of pixels, and a signal controller which receives an input image signal and an input control signal to control the data driver, where the signal controller calculates a ratio of a first type of pattern in a image based on the input image signal, generates a polarity signal based on the ratio of the first type of pattern, and transmits the polarity signal to the data driver.

The present invention relates to a display device capable of reducing power consumption and preventing flicker, as well as a driving method thereof. An exemplary display device includes: a display panel configured for display of a still image and a motion picture; a signal controller programmed to transmit control signals for driving the display panel; and a graphic processing unit transmitting input image data to the signal controller. The signal controller includes a frame memory storing the input image data, and the display panel is driven at a first frequency when the motion picture is displayed and alternatingly driven at the first frequency and a second frequency when the still image is displayed, the second frequency being lower than the first frequency.
