Patent ID: 7965266

Claim:
An image display unit, comprising: a screen, the screen emitting detection light together with display light and detecting the emitted detection light reflected from a target object, the detection light being in an invisible wavelength range, the display light corresponding to image data, wherein the target object is detected on the basis of the detection light; a plurality of first light-emitting devices emitting light in a visible wavelength range; a second light-emitting device emitting light in an invisible wavelength range; a plurality of light-receiving devices receiving light in an invisible wavelength range; a first light emission driving means for driving the plurality of first light-emitting devices on the basis of the image data so as to emit the display light from the screen; a second light emission driving means for driving the second light-emitting device so as to emit the detection light from the screen; a first light reception driving means for driving the plurality of light-receiving devices so as to detect, on the screen, the detection light emitted from the second light-emitting device and reflected from the target object; and a detecting means for detecting the target object on the basis of light reception signals obtained from the light-receiving devices, wherein each of the first light-emitting device and the second light-emitting device is a self-luminous device, wherein each of the first light-emitting device and the second light-emitting device is an organic EL device, and wherein the second light-emitting device is an organic EL device including: a pair of substrates facing each other, one of the substrates on a side closer to the screen having light transparency, and an invisible light emission layer disposed between the pair of substrates and emitting light in an invisible wavelength range.
