Abstract
The present invention relates to an image display device. An image display device according to an embodiment of the present invention comprises: a display; and a wireless transmission device which is spaced apart from the display and transmits image data to the display by a wireless communication method, wherein the wireless transmission device includes at least one antenna device for wirelessly transmitting image data to the display, and the wireless transmission device generates, for beamforming tracking of a beam output from the antenna device, a beamforming candidate list including some of a plurality of antenna-based indexes corresponding to a peripheral region around the antenna device, and when a difference in a signal-to-noise ratio or a metric difference between a first index and a second index adjacent to the first index among some of the plurality of antenna-based indexes is less than a beam gain, the wireless transmission device excludes the second index from the beamforming candidate list. Accordingly, it is possible to quickly perform beamforming tracking when a blocker occurs between the wireless transmission device and the display, which are arranged apart from each other.
