TOUCH DISPLAY DEVICE

摘要

PURPOSE: A touch display device is provided to improve a decline of a recognition ratio caused by a difference of a light size of an intrinsic light signal and reduce an error probability when realizing a touch by using a self-lighting type panel. CONSTITUTION: A panel(100) generates an intrinsic light signal. A controller(140) controls the panel. A input unit(150) senses a location of the panel through the intrinsic light signal and transmits information obtained through sensing to the controller. The panel receives a first video signal from a first direction to a second direction for a first time and receives a second video signal from the second direction to the first direction for a second time. The panel receives the first video signal from the first direction to the second direction for the first time and receives the second video signal from the second direction to the first direction for the second time by a data driver providing the video signal.
