Abstract:
A display device includes: a display panel; a sensor unit on the display panel; a touch driver including a signal processor configured to output a final touch point coordinate using a touch sensing signal received from the sensor unit; and an application processor configured to provide filter size information to the touch driver, wherein the signal processor includes a jitter remover configured to receive a current touch point coordinate from a coordinate calculator and to output the final touch point coordinate from which a jitter component is removed by filtering with a jitter filter, and wherein the jitter remover includes a filter size determiner configured to vary a range of the jitter filter in response to the filter size information.
