The PT-RZ12KU 12000 lumens WUXGA 3-chip DLP laser projector. It features high picture quality in a very compact and lightweight body.<p><B>Diagram for 3-Chip DLP™ Laser Projector:</B><p>Combining 3-Chip DLP™ imaging with Panasonic’s original SOLID SHINE Laser technology, the PT-RZ12K Series achieves truly stunning picture quality. Two powerful solid-state laser light sources, a heat-resistant phosphor wheel, and three independent DLP™ chips for red, green, and blue ensures class-leading brightness, color accuracy, and contrast. Heat-resistant phosphor wheel ensures high brightness and excellent reliability for long periods.<p><B>Accurate Color Reproduction:</B><p>The PT-RZ12K Series captures a more accurate Rec. 709-compliant color space than comparable laser projectors. A blue laser ensures greater precision, while an expanded color gamut improves white balance accuracy.<p><B>Ultra-Durable Laser Optical Engine for Continuous 24-hour Operation:</B><p>Dual Drive Laser Optical Engine uses two discrete light sources grouping laser diodes into modules. A failsafe laser light source redundancy circuit ensures minimal reduction in brightness and color uniformity in the event of laser diode failure, making PT-RZ12K Series ideal for mission-critical applications. Further, brightness decreases gradually and in a linear rather than exponential fashion (as is common to lamp-based projectors) over its 20,000-hour maintenance-free service life.<p><B>Lower Total Cost of Ownership:</B><p>Large, pin-sharp images will not burn a hole in your pocket. Expect up to 20,000 hours maintenance-free service at full power with no filters to clean or replace thanks to a fully sealed optical block. At this time the brightness will have decreased to approximately half of its original level (Dynamic Contrast Mode: 3, Image Mode: Dynamic). Panasonic recommends cleaning or checkup at point of purchase after every 20,000-hour period (approximately). Light source lifetime may be reduced depending on environmental conditions. Replacement of parts other than the light source may be required in a shorter period.
