TOUCH CONTROLLER HAVING INCREASED SENSING SENSITIVITY, AND DISPLAY DRIVING CIRCUIT AND DISPLAY DEVICE AND SYSTEM HAVING THE TOUCH CONTROLLER
First Claim
1. A touch display driver integrated chip (TDDI) comprising:
- a display driving unit comprising;
a source driver configured to drive a source line of a display panel; and
a timing controller configured to control the source driver; and
a touch controller configured to detect an electrical change of sensing units of the display panel,wherein the display driving unit and the touch controller are included in the TDDI, andwherein an operation of the display driving unit and an operation of the touch controller are synchronized with each other.

Abstract
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.
