## Abstract

A display device includes a display panel, at least one touch sensor, a touch sensor controller and a display controller. The at least one touch sensor senses and outputs a touch sensing signal. The touch sensor controller, electrically coupled to the touch sensor, receives the touch sensing signal and generates a touch sensing result accordingly. The display controller, electrically coupled to the display panel and the touch sensor controller, receives graphic data to generate first display data and determines whether to adjust the first display data to second display data and transmit the second display data to the display panel according to the touch sensing result. The first display data has first display a feature, the second display data has a second feature, and the first display feature is different from the second display feature. An operating method of the display device is also provided.
