a touch panel on the display panel;
a host processor which receives proximity data of the touch panel; and
a display panel driver which receives an input control signal from the host processor and drives the display panel based on the input control signal;
wherein the touch panel includes a proximity area and a non-proximity area,
wherein the host processor counts a rise of the proximity data in the proximity area to generate a first count value, and
wherein the host processor resets the first count value when the proximity data in the non-proximity area increases.
