Abstract: A luminance controller including: a luminance calculator for calculating an average luminance of each of pixel blocks obtained by dividing a display panel, based on image data of a current frame; a pop-up detector for detecting an image pop-up by determining a number of luminance change blocks between a previous frame and the current frame among the pixel blocks; and a tone map controller for controlling a change in tone map curve of a gray scale of the image data, based on the detected result of the pop-up detector.

Abstract: A touch panel includes: a first electrode pattern arranged in a first direction, including a plurality of first electrode cells that are physically separated from each other; a second electrode pattern arranged in a second direction crossing the first direction, including a plurality of second electrode cells that are physically separated from each other; first touch signal lines connected to the first electrode cells; and second touch signal lines connected to the second electrode cells. The electrode patterns and the touch signal lines are arranged on the same layer on a substrate such that a first virtual connection line for connecting centers of second electrode cells of a first group corresponding to an n-th first electrode cell crosses a second virtual connection line for connecting centers of second electrode cells of a second group corresponding to an (n+1)-th first electrode cell.

Abstract: A touch sensor device includes first electrode patterns arranged in a first direction and physically separated first electrode cells; second electrode patterns arranged in a second direction crossing the first direction and includes physically separated second electrode cells; first touch signal lines connected to the first electrode cells; second touch signal lines connected to the second electrode cells; and a touch sensor controller connected with the first touch signal lines and the second touch signal lines. The first electrode cell and the second electrode cell adjacent in the first direction form a channel for generating position information by a mutual capacitive method. The touch sensor controller stores a ghost table including a ghost ratio for each channel for a touch position, and removes a ghost from measured touch data by using the ghost table to generate final touch data.
