Document Type and Number:
WIPO Patent Application WO/2019/143122
Kind Code:
A1
Abstract:
The present invention provides a display device, a display system, and a control method therefor, which can highly accurately derive the location of an input device, with efficient power consumption, by using a radar system without being affected by the surrounding environment. The display system according to an embodiment comprises: a display unit; an input device for transmitting an initial location signal; a plurality of antennal modules for transmitting location detection signals, receiving reflected signals which are reflections of the location detection signals from the input device and objects around the input device, and receiving the initial location signal transmitted by the input device; and a control unit for performing control such that a pointer is displayed on the display unit according to a current location of the input device, determined on the basis of the initial location signal and the reflected signals.
