Single pixel monochromatic display and signal-receivable module, and a device containing the module


A single pixel monochromatic display and signal-receivable module, and a device containing the module; the module is mainly a combination of a set of lenses and a color mixing screen; light beams projected from color light sources are converged through a light convergent plate, and then refracted through the light refractive color convergent plate which has refraction curved surfaces to same locations on a color mixing screen on which a single color is formed and a single pixel is thereby constituted; even subject to enlargement, there are no more tri-colors in a single pixel but only one single color in a single pixel; the module can also be used to emit or receive invisible electromagnetic waves, or can receive electromagnetic wave signals of another wave length during display.. .
