Abstract:
A display apparatus includes a display panel which include a plurality of areas; a communication unit which receive information about brightness sensed by a pointing device; a backlight unit which includes a plurality of light sources; and a controller which controls the backlight unit to change the brightness of the plural areas by a predetermined unit, and determines a pointing position of the pointing device on the basis of relative variation in the information about the brightness. With this, it is possible to detect a pointing position of a pointing device in a display apparatus having a hold-type display panel.
