ABSTRACT:
A liquid crystal display includes a backlight that provides light and selectively modifies the transmission of light from the backlight to the front of the display. The backlight includes a plurality of spaced apart light waveguides and a plurality of selection elements associated with the light waveguides that change the characteristics of the material of the light waveguides to selectively direct the transmission of light toward the liquid crystal layer. The combination of the waveguides and the selection elements provide light to the front of the display in a temporal manner during a frame.
