Abstract
A display apparatus having a noncontact input function is provided. The display apparatus has a first function of detecting, with a light-receiving device, light irradiated from a light source outside a display portion and blocked by a pointing object to recognize the position pointed by the pointing object, and a second function of detecting, with the light-receiving device, light irradiated from a light source inside or outside the display portion and reflected by the pointing object to recognize the position pointed by the pointing object. The display apparatus can operate by switching the first function and the second function in accordance with the intensity of the light irradiated from the light source outside the display portion.
