Abstract
A touch input device includes a communication module receiving external light characteristic information. A code detector emits infrared light and receives infrared light reflected from a display panel to detect code patterns of the display panel. A light emitting driver controls an infrared light emission operation of the code detector. A code processor modulates an emission control signal so that an infrared light emission characteristic of the code detector is changed according to a change in the external light characteristic information and controls driving of the light emitting driver.
