Abstract
To achieve desired display on a display surface and accurate image capture in a display device with an imaging function. A light source for display (a first light-emitting element) and a light source for image capture (a second light-emitting element) that does not adversely affect display when it is on are separately provided in the display device with an imaging function. In the display device, an image can be appropriately captured using the light source for image capture in a period during which display is performed using the light source for display. Consequently, desired display on the display surface and accurate image capture can be achieved in the display device.
