Abstract: 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.

Abstract: A display apparatus includes a timing controller configured to convert input image data into a hue, saturation, brightness (HSV) color space to generate a saturation histogram, generate a saturation gain curve and a dimming value based on the saturation histogram, control saturation of an input image based on the saturation gain curve to generate a data signal, and control luminance of the input image based on the dimming value to generate a light source control signal. A data driver is configured to generate data voltages based on the data signal. display panel is configured to display an output image based on the data voltages. A light source is configured to provide light to the display panel based on the light source control signal.

Abstract: An image processing controller, a display device including the image processing controller and a driving method of the display device are disclosed. In one aspect, the method includes receiving an image signal and gamma correcting the image signal into at least one main area image signal. The method also includes interpolating the main area image signal into a boundary area image signal. The method further includes dithering the main area image signal and the boundary area image signal into a data signal and providing the data signal to a display panel.

Abstract: A liquid crystal display device may include gate lines, data lines intersecting the gate lines, and pixels electrically connected to the gate lines and the data lines and arranged in pixel columns and pixel rows. The data lines include first-type data lines and second-type data lines. Exactly one pixel column is positioned between every immediately neighboring two of the first-type data lines. No pixel column is positioned between any immediately neighboring two of the second-type data lines. Each of the first-type data lines is electrically connected to a pixel of a first immediately adjacent pixel column in every odd-numbered pixel row and is connected to a pixel of a second immediately adjacent pixel column in every even-numbered pixel row. Each of the second-type data lines is electrically connected to a pixel of exactly one immediately adjacent pixel column in every other pixel row.
