Abstract

The present invention is to reduce power consumption in a display that concurrently (or alternately) implements light emission and light reception in parallel. A display is provided with a display panel configuration including a plurality of display elements arranged in a matrix and a plurality of light-receiving elements that are disposed adjacent to the plurality of display elements and receive light incident on a display plane. In addition, the display includes a position detector that determines the position of contact or proximity to the display plane based on a light reception signal arising from light reception by the light-receiving elements. Furthermore, the display includes a controller that shifts the displaying state or the position detection state from the low power consumption mode to the normal operation mode if the position detector has determined the presence of contact or proximity in a predetermined state.
