Abstract
A vehicle display apparatus includes a display, a plurality of light emitting units provided in the periphery of the display, a plurality of light receiving units provided in the periphery of the display, and a processor configured to calculate a position of an approaching external object based on levels of light signals received by the plurality of light receiving units. The plurality of light emitting units sequentially emits light, the plurality of light receiving units sequentially receives light in correspondence with sequential light emission of the plurality of light emitting units, and the processor calculates the position of the external object based on the levels of the light signals received by the plurality of light receiving units in correspondence with sequential light emission of the plurality of light emitting units. Accordingly, it is possible to stably detect the position of the external object positioned in front of the display.
