Abstract: An electronic pen for detecting a touch location on a display panel by detecting infrared rays generated by the display panel, the electronic pen including an infrared sensor that detects the infrared rays and generates a detection signal; an amplifying unit that amplifies the detection signal; a low pass filter that filters high-frequency elements from the amplified detection signal; and a location detecting unit that detects the location on the display panel touched by the electronic pen based on the filtered detection signal.

Abstract: A light scan type touch panel includes: at least two light scanning units located outside of a display screen at one side; a plurality of light guide units located at other sides of the display screen; and a light receiving unit located at at least one end of each of the plurality of light guide units. Each of the light guide units includes: a light guiding member having a light incidence plane and a light emission plane; a diffusion sheet located at the light incidence plane; a plurality of reflection sheets located at planes of the light guiding member other than the light incidence plane and the light emission plane; and diffuse reflection inducing units located at one side of the light guiding member, facing one of the plurality of reflection sheets.

Abstract: An electronic pen for detecting a touch location, a controlling method of the same and a driving method of a plasma display apparatus are disclosed. According to embodiments of the present invention, synchronization between the electronic pen and the plasma display apparatus may be performed. An electronic pen includes a sensor for receiving infrared emissions and for generating a plurality of sensing signals in response to the infrared emissions, a synchronization unit for determining a synchronization timing in accordance with timings of the plurality of sensing signals, and a coordinate detection unit for detecting an emission location of the infrared emissions in accordance with time differences between the synchronization timing and the timings of the plurality of sensing signals.
