Display device and display method

Abstract

A display device and a display method are provided in which the influence of the outside light can be removed easily, in the case where light-emitting and light-receiving are performed in parallel and simultaneously. In the case where an image-display and a light-receiving are performed simultaneously or alternately on a display surface of the display device, processing of making the display surface emit light to display an image is performed; light entering the display surface is received, which is the light-receiving of two times of a state in which the light-emitting for display use is being performed (step S11) and of a state in which light is not emitted (step S12); and a state in which the display surface is touched or approached is detected based on the detection of a difference in the quantities of received light of the two times (step S13).
