Three-dimensional interactive display

摘要

Provided is a thin three-dimensional interactive display which enables multi-touch sensing and three-dimensional gesture recognition. The three-dimensional interactive display includes a light source 11 for irradiating an object 15 to be detected with a light, a light modulation layer 12, into which a scattered light 17 generated by irradiating the object 15 with the light 16 from the light source 11 enters, at least for modulating an intensity of the scattered light 17, a transparent light-receiving layer 13 for receiving the light transmitted through the light modulation layer 12, and a display panel 14 or a back light panel disposed on the opposite side of the transparent light-receiving layer 13 from the light modulation layer 12. The transparent light-receiving layer 13 has a two-dimensional array of light-receiving elements D.
