US 2018/0005567 A1 · ELECTRONIC DEVICE AND METHOD FOR DRIVING THE SAME

Abstract

An electronic device includes a display portion, an imaging portion, a control portion, an input portion, and a sensor portion. The display portion has a first display element that reflects visible light and a second display element that emits visible light. The display portion has a function of displaying an image using one of or both first light reflected by the first display element and second light emitted from the second display element. The imaging portion takes an image of an object, the control portion controls the display portion and the imaging portion, the input portion inputs a signal for controlling the display portion and the imaging portion to the control portion, and the sensor portion outputs sensing data to the control portion, in consideration of illuminance of external light. Such a display device increases the display quality, or keeps high-quality display regardless of environmental conditions and reduces power consumption.
