ABSTRACT:
A backlight for a color liquid crystal display uses various techniques for activating colored phosphors, which emit colored light to each one of several sub-pixels within a particular liquid crystal display pixel. Activation of the colored phosphors may be performed using field emission devices, both diode and triode, a fluorescent lamp, thin film electroluminescent light, an ultraviolet lamp, a thermionic emitter, or a high-intensity glow discharge lamp. LCD panels are manufactured using less than four glass substrates.
