Abstract: A touch sensor controller for driving a touch sensor that is stacked on a display panel and includes driving electrodes and receiving electrodes crossing the driving electrodes, the touch sensor controller including: a driving circuit configured to sequentially provide driving signals to the driving electrodes; a read-out circuit configured to, in response to the driving signals, generate touch data based on first sensing signals received from the receiving electrodes and generate display noise data based on a second sensing signal received from a first driving electrode to which a driving signal of the driving signals is not applied from among the driving electrodes; and a touch processor configured to determine whether a touch input has occurred on the touch sensor based on the touch data and the display noise data.

Abstract: To compensate for degeneration of an electroluminescent display device, a method of compensating for the degeneration may include, grouping a plurality of pixels in a display panel into a plurality of pixel blocks arranged in present block rows and present block columns based on initial block boundaries, accumulating block stress values based on input image data, each accumulated block stress value representing a degeneration degree of the pixels included in each pixel block of the plurality of pixel blocks, performing a boundary updating operation on the plurality of pixel blocks, the performing the boundary updating operation including moving present block boundaries of the plurality of pixel blocks to updated block boundaries based on a distribution of the accumulated block stress values, and correcting the input image data based on the accumulated block stress values and the updated block boundaries.

Abstract: A display driving circuit for driving a display panel includes a control logic that adjusts brightness of a first partial area by adjusting pixel data values included in partial image data to be displayed on the first partial area of the display panel based on received brightness control information, and a data driver that generates image signals by digital-analog conversion of pixel data values provided from the control logic, the data driver providing the image signals to the display panel.
