TOUCH CONTROLLER HAVING INCREASED SENSING SENSITIVITY, AND DISPLAY DRIVING CIRCUIT AND DISPLAY DEVICE AND SYSTEM HAVING THE TOUCH CONTROLLER

摘要

A touch controller includes a touch data generator that is connected to a plurality of sensing lines, the touch data generator sensing a change in capacitance of a sensing unit connected to each of the sensing lines and generating touch data by processing the sensing signal corresponding to the result of sensing; and a signal processor that controls a timing of generating the touch data by receiving at least one piece of timing information for driving a display panel from a timing controller, and then providing either the timing information or a signal generated from the timing information as a control signal to the touch data generator.
