Abstract:
1. An image display unit comprising: a light source that emits a light; a pair of transparent substrates; a liquid crystal layer disposed between the pair of transparent substrates; a transmission layer that includes first and second filters, the first filter configured to transmit a first light from the light and a second filter configured to transmit a second light from the light; a plurality of pixels, each pixel including a first sub-pixel element that modulates the first light to a visible wavelength range based on image data, a second sub-pixel element that modulates the second light to an invisible wavelength range, and a third sub-pixel element that receives reflected light, the reflected light being the second light that is reflected from a target object; a display driving means for driving the first sub-pixel element of the plurality of pixels based on the image data to emit the first light in the visible wavelength range; a light reception driving means for driving the second sub-pixel element of the plurality of pixels to receive the reflected light; and a detecting means for detecting the target object based on the reflected light.
