Abstract
A liquid crystal display includes: a liquid crystal panel; a plurality of first light sources disposed below the liquid crystal panel; a first diffusion member disposed between the liquid crystal panel and the first light sources; a plurality of second light sources disposed below the liquid crystal panel and which emit a sensing signal toward the liquid crystal panel; and a plurality of sensors disposed in or below the liquid crystal panel. The sensing signal emitted from the plurality of second light sources toward the liquid crystal panel is reflected by an object disposed above the liquid crystal panel and is detected by the plurality of sensors before transmitting through the first diffusion member away from the liquid crystal panel such that a shape of the object is determined based on the sensing signal reflected from the object and detected by the plurality of sensors.
