A method of image processing includes extracting first image information from an input image by analyzing the input image, determining, based on the first image information, whether to utilize a high dynamic range (HDR) function for the input image, setting an image output mode based on a result of the determination, setting a reference tone curve for the input image based on the image output mode, and generating an output image by converting the input image based on the reference tone curve.

Method of image processing and display apparatus performing the same

Provided if a display device including a liquid crystal panel, a common voltage generator configured to generate a common voltage, and a common voltage compensator. The liquid crystal panel includes gate lines, data lines, pixels, and a common electrode. The pixels include first pixels and second pixels. The first pixels and the second pixels are respectively disposed in pixel rows adjacent to each other, respectively constitute different columns, are connected to the same gate line, display the same color, and receive data voltages having different polarities. When a boundary of a pattern included in image data, extending in a first direction, lies between the first pixels and the second pixels, the common voltage compensator is configured to compensate the common voltage.

Display device and driving method thereof

According to an embodiment, a display apparatus includes gate lines extending in a first direction, data lines extending in a second direction crossing the first direction, and pixels connected to the gate lines and the data lines. The pixels include pixels arranged in a k-th row and pixels arranged in a (k+1)th row disposed adjacent to the pixels arranged in the k-th row in the second direction. An (i+1)th gate line is disposed between the pixels in the k-th row and the pixels in the (k+1)th row. A first pixel arranged in a g-th column among the pixels arranged in the k-th row and a second pixel arranged in the g-th column among the pixels arranged in the (k+1)th row are connected to a j-th data line. The pixels arranged in the k-th row are alternately connected to an i-th gate line and the (i+1)th gate line.

Display apparatus and method of driving with pixels alternatively connected to adjacent gate lines

A display apparatus includes a dot formed from a plurality of pixels. Each pixel displays a grayscale that is a sum of a first image displayed during an Nth frame and a second image displayed during an (N+1)th frame. N is an integer equal to or greater than 1. The dot includes first and second pixels having a first color, the first pixel displaying an image having a first grayscale based on a first gamma curve, and the second pixel displaying an image having a second grayscale based on a second gamma curve. Third and fourth pixels have a second color and display images having the first grayscale based on the first gamma curve. Fifth and sixth pixels have a third color and display images having the second grayscale based on the second gamma curve.
