Abstract: Disclosed is display apparatus for a vehicle including a display unit, a gesture sensing unit located around the display unit for sensing a 3D gesture made by an object, and a processor for generating a control signal based on the 3D gesture. The gesture sensing unit includes a first light-emitting unit for emitting a first group of rays along a first optical path, a second light-emitting unit for emitting a second group of rays along a second optical path, and a light-receiving unit for receiving a first group of reflected rays formed when the first group of rays is reflected by the object and a second group of reflected rays formed when the second group of rays is reflected by the object.
