摘要:
The driving apparatus of a display device calculates a slope using a minimum gray, a maximum gray, a gray average of frame data in a current frame, and a gray average of frame data in a previous frame, and corrects and outputs the input frame data according to the slope, using frame data of one frame. As a result, a gray range of the input image signal can be extended, thereby improving visibility. Further, in a case of a motion picture, even when a difference of a gray range of images of adjacent frames is large, an original image is not distorted due to extension of a gray range. Also, even when noise is included in the input image signal, a gray range can be extended after removing the noise.

An electrophoretic display (“EPD”) includes a display panel displaying an image and a gray-scale generator generating a gray-scale and providing a gray-scale voltage to the display panel. The gray-scale generator generates a gray-scale value of a white color using gray-scale values of red, green and blue colors and a brightness ratio between the red, green and blue colors. When a pure color is displayed, the EPD prevents the gray-scale of the white color from being fixed to 0. Thus, the EPD may enhance a chroma of the pure color and color brightness, thereby improving a display quality thereof.

A color filter substrate includes a base substrate, a white light-blocking part, and a color filter layer. The white light-blocking part is formed on the base substrate. The white light-blocking part divides the base substrate into a light-transmitting area and a light-blocking area. The color filter layer is formed in the light-transmitting area. Therefore, the white light-blocking part is formed so that a boundary of the pixel part is divided and a light-blocking function is realized. Furthermore, a white luminance characteristic is enhanced.

A method of displaying images on an electrophoretic display (“EPD”) panel includes displaying a (K)-th image on the EPD panel including a plurality of electrophoretic particles, wherein K denotes a natural number. Then, when an interrupt signal for converting images is inputted during one of a plurality of driving intervals, a charge of the electrophoretic particles is compensated, which is charged in correspondence with the (K)-th image displayed on the EPD panel before the interrupt signal is inputted, and then a (K+1)-th image is displayed on the EPD panel. Thus, when the interrupt signal is inputted during one of the driving intervals displaying the (K)-th image data, the charges that are charged in the particles are compensated in correspondence to the (K)-th image data, and then the (K+1)-th image is displayed so that display quality may be enhanced.

An electrophoretic display includes a lower substrate, an upper substrate, a color display layer on the lower substrate, a pixel electrode on the lower substrate, and a common electrode on the lower substrate or the upper substrate. The common electrode does not overlap the pixel electrode, and an electrophoretic active layer having a dispersion medium and electrophoretic particles is arranged between the lower substrate and the upper substrate. The electrophoretic active layer is a single-polarity electrophoretic particle system, and grayscales are generated depending on the number of electrophoretic particles arranged in a portion of the electrophoretic active layer corresponding to the pixel electrode. The position of the electrophoretic particles is controlled by the magnitude of the electric field applied between the pixel electrode and the common electrode.
