Pointing device and display apparatus

摘要

A pointing device and a display apparatus applying the same are provided. The pointing device comprises an optical sensor which senses a plurality of optical signals emitted by the display apparatus, and a controller which calculates a current location pointed by the pointing device on a screen of the display apparatus divided into a plurality of blocks, based on points of time at which the plurality of optical signals are sensed by the optical sensor on the screen of the display apparatus. The controller calculates the current location using the plurality of blocks, and corrects a location error that occurs when the current location pointed by the pointing device is located adjacent to a boundary area between at least two adjacent blocks among the plurality of blocks.
