Abstract:
A LCD system including multiple light sources optically coupled through different light entry regions to at least one waveguide element positioned to backlight a LCD panel. A LCD system including multiple light sources coupled to light entry regions of two or more waveguides comprising a waveguide system positioned to backlight a LCD panel. Waveguides of various configurations and promoting even lighting of associated LCD panels are provided. Resulting LCD systems enable uniformly lit panels having diagonal measurements in excess of 12 to 14 inches, but the invention is not limited to panels of any particular size.
