description Disclosed is a method of detecting a hovering object, the method including: an operation of precharging a compensation capacitor and a parallel capacitor, which is obtained by connecting in parallel a self-capacitor formed between an object hovering over a touch panel and an electrode of the touch panel and a parasitic capacitor of the touch panel, with a predetermined voltage; a first charge sharing operation of sharing charges by connecting the parallel capacitor and the compensation capacitor in series; a second charge sharing operation of sharing charges by connecting the parallel capacitor and the compensation capacitor in parallel; and an operation of outputting an electrical signal provided by the parallel capacitor while the parallel capacitor and the compensation capacitor are connected in parallel.
