Abstract
A display device is disclosed. The display device may include a display panel in which a plurality of pixels may be arranged in a display area to display an image, a scan driver to drive gate lines of the display area, a data driver to drive data lines of the display area, a display driver to sort interpolated image data according to resolution of the display area, to supply the sorted interpolated image data to the data driver, and to control driving timings of the scan driver and the data driver, and a data interpolator to modulate and interpolate image data of pixels, which may be input from an outside, according to driving characteristics of the display panel and to generate and output the interpolated image data.
Claims19
A display device comprising:
- a display panel in which a plurality of pixels are arranged in a display area to display an image;
- a scan driver to drive gate lines of the display area;
- a data driver to drive data lines of the display area;
- a display driver to sort interpolated image data according to resolution of the display area, supply the sorted interpolated image data to the data driver, and control driving timings of the scan driver and the data driver;
- and
- a data interpolator to modulate and interpolate image data of pixels, which are input from outside, according to driving characteristics of the display panel and generate and output the interpolated image data,
- wherein the data interpolator is to interpolate grayscale values or luminance values of the image data of the pixels, compare image data of adjacent pixels in the process of interpolating the image data of the pixels which are sequentially input and, when the image data of the adjacent pixels are matching within one or more standard deviations according to a result of interpolating the grayscale values or the luminance values, apply previously generated interpolated image data as interpolated image data for the image data of the adjacent pixels.
