Abstract: An improved approach is described to implement an LED-based large area display which uses an array of single color solid state lighting elements (e.g. LEDs). In some embodiments, the panel comprises an array of blue LEDs, where each pixel of the array comprises three blue LEDs. An overlay is placed over the array of blue LEDs, where the overlay comprises a printed array of phosphor portions. Each pixel on the PCB comprised of three blue LEDs is matched to a corresponding portion of the overlay having the printed phosphor portions. The printed phosphor portions of the overlay includes a number of regions of blue light excitable phosphor materials that are configured to convert, by a process of photoluminescence, blue excitation light generated by the light sources into green or red and colored light. Regions of the overlay associated with generating blue light comprise an aperture/window that allows blue light to pass through the overlay.
