ELECTRONIC PEN FOR DETECTING TOUCH LOCATION, CONTROLLING METHOD OF THE SAME, AND DRIVING METHOD OF PLASMA DISPLAY APPARATUS |
摘要 |
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.
