Abstract
A display device with built-in touch sensors comprises: a display panel with built-in touch sensors; and a touch driver that converts a sensed voltage of the touch sensors into sensed data, wherein the touch driver comprises: an enable signal generator that compares the sensed voltage with a preset offset voltage and outputs an enable signal at a first level if the sensed voltage is higher than or equal to the offset voltage and outputs the enable signal at a second level if the sensed voltage is lower than the offset voltage; and an analog-to-digital converter that converts the sensed voltage into the sensed data when the enable signal is at the first level.
