1. A pointing device comprising:
- a sensor which detects a first signal and a second signal;
a storage unit which stores a preset signal pattern; and
a controller which generates a first pattern that represents a time at which the first signal is detected, compares the preset signal pattern to the first pattern, and generates location data corresponding to a time at which the second signal is detected according to a result of comparison.

Abstract
A pointing device, a display apparatus and a pointing system, and a location data generation method and a display method using the same are provided. The pointing device includes a sensor that detects signals, a storage unit which stores a signal pattern and a controller which generates location data corresponding to a time at which a signal is detected. Using the detected signals, it is possible to more precisely determine a location of the pointing device on a display apparatus, and to minimize errors caused by delays that may occur when the pointing device is wirelessly connected to the display apparatus.

11. A display apparatus comprising:
-
a display panel; a driving unit which applies a driving voltage to the display panel; and a controller which controls the driving unit to apply the driving voltage to the display panel at a first time and at a second time, wherein the display panel emits a first signal having a first pattern when the driving voltage is applied at the first time and emits a second signal when the driving voltage is applied at the second time. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A display method comprising:
-
emitting a first signal having a first pattern; emitting a second signal; detecting the first signal and second signal, and generating, if the first pattern is at least partly identical to a pre-stored pattern, data regarding a location on a display in which the first signal and second signal are detected based on the second signal; and displaying an output based on the generated data at the location.
