Patent ID: 8884899

Claim:
A three-dimensional interactive display, comprising: a light source configured to irradiate an object to be detected with a light; a light modulation layer, into which a scattered light generated by irradiating the object with the light from the light source enters, configured to have at least a capability of modulating an intensity of the scattered light; a transparent light-receiving layer configured to receive the light transmitted through the light modulation layer; and one of a display panel and a back light panel, which is disposed on the opposite side of the transparent light-receiving layer from the light modulation layer; the light source generates ultraviolet light or infrared light; the light source is configured to generate the light so that the light irradiates the whole space in front of a screen of the three-dimensional interactive display; the light modulation layer is a liquid crystal panel; the display panel is an organic light-emitting diode display panel, a plasma display panel or a liquid crystal display panel; and the transparent light-receiving layer includes a light-receiving element array on which a plurality of light-receiving elements is arranged, each of which has a photoconductor containing a complex of a conductive polymer and/or polymer semiconductor and at least one of a protein containing a dye having a long-lived excited state, an organic dye, and an inorganic dye.
