The PT-121 chipset is a derivative of the PT-120 that consists of individually packaged Red, Green and Blue LEDs, each with a monolithic emitting area of 12 mm2, and a 4:3 aspect ratio optimized by not limited to XGA and SXGA+ resolutions.
The PT-121 is targeted for projection systems using micro-displays ranging from 0.65" to 1". PT-121 is an ideal light source for lamp-free front projectors in business, education or commercial applications
Like all Luminus projection Big Chip LEDs, the PT-121 can be used with DLP®, LCoS and HTPS LCD micro-displays. PT-121 devices are also available in chipset or individually for high performance illumination applications
