Abstract
An LED backlight apparatus includes a plurality of radiation emitting diodes, each diode emits radiation having a peak wavelength of about less than 430 nm. Each diode is located on a back surface of a housing. The housing may have an opening. A screen covers the opening and the screen includes a discrete pattern of phosphor coated red light emitting pixels, a second discrete pattern of phosphor coated green light emitting pixels, and a third discrete pattern of phosphor coated blue light emitting pixels. The emitted radiation may excite the phosphor coated pixels. The apparatus may also include a radiation regulating element proximate the screen and further include a diffuser proximate the diodes.
