Abstract
A touch sensor display device and an interface method thereof are provided. The touch sensor display device comprises a display panel in which a touch panel, gate lines, data lines, sensing lines, and subpixels are disposed; a gate driver circuit drives the gate lines; a data driver circuit drives the data lines; a touchscreen driver circuit drives the sensing lines, and includes a sleep module which controls switching to a sleep mode, and a wake-up module which performs a wake-up function to cancel and return to a normal state, and transmitting a sleep mode signal pattern or a wake-up signal pattern to the micro control unit; and a micro control unit determining whether a touch is detected, by the touchscreen driver circuit. Accordingly, power consumption is reduced in the display device. A mode change is performed by a driver circuit to enable rapid mode changes while reducing power consumption.
