Abstract: A display apparatus includes gate lines extending in a first direction, data lines crossing the first direction and having polarities of data voltages consecutively repeated every four data lines, and pixels which each comprise three sub-pixels. One of the three sub-pixels has a width in the first direction different from a width in the first direction of another sub-pixel of the three sub-pixels. Each of the three sub-pixels is connected to a corresponding gate line and a corresponding data line. The polarities of the data voltages applied to a first data line and a third data line are opposite and the polarities of the data voltages applied to a second data line and a fourth data line are opposite. The pixels arranged between two adjacent data lines among the plurality of data lines are alternately connected to the two adjacent data lines.

Abstract: A display apparatus includes a display panel including a plurality of pixels, and a driver which receives input image data, generates final image data by compensating the input image data to increase luminances of pixels disposed in at least one edge portion of the display panel among the plurality of pixels, and drives the display panel based on the final image data. The input image data for a pixel of the pixels is compensated based on a compensation constant determined according to a position of the pixel when the input image data for the pixel represents a gray level higher than or equal to a first reference gray level, and is compensated based on a reduced compensation constant that is reduced from the determined compensation constant when the input image data for the pixel represents the gray level lower than the first reference gray level.

Abstract: In an image processing method that converts image data into output data by performing tone mapping, an edge of an image represented by the image data is determined, a first tone mapping operation is performed on first image data included in the image data, where the first image data represent a first portion of the image not including the edge, whether a gray level of second image data is within a predetermined gray range is determined, where the second image data represent a second portion of the image including the edge, a second tone mapping operation is performed on the second image data when the gray level of the second image data is within the gray range, and the first tone mapping operation is performed on the second image data when the gray level of the second image data is not within the gray range.

Abstract: Provided is a display device. The display device includes: a gamma mapping unit; a compensating signal generation unit including a limit gray scale determination unit outputting a white limit gray scale value; and a hue control compensation unit including a main color compensation unit and a white compensation unit. The white compensation unit decreases a gray scale value of the white image signal based on the white limit gray scale value to generate the white compensated signal and the main color compensation unit compensates the red, green and blue image signals based on the white limit gray scale value to generate the red, green and blue compensated signals, when gray scale value of the white image signal is larger than the white limit gray scale value.
