Abstract:
Provided are a capacitive touch detecting device, a capacitive touch detecting method, and a touch screen panel, using a level shift, and a display device having a built-in touch screen panel, which minimizes an influence due to noise or a parasitic capacitance, and detects a touch input by positively using a signal induced by a common electrode of a liquid crystal display (LCD).
