Superior Bright Precision-Aligned High-Output Laser Source Zero-deviation alignment of BlueCore laser diodes boosts luminous flux into the light tunnel, improving light efficacy to 4,000 lumens. |
Superior Performance Secondary Yellow-Infused Color Wheel Dual synchronized BlueCore color wheels utilize an additive yellow segment, stimulating precise RGBY spectra for optimal chromatic performance. |
Superior Durability Hermetically Sealed DLP Chip Comprising over two million micromirrors that reflect pure light through the color wheel, the DLP chip is hermetically sealed to resist heat for over 100,000 hours without degradation. |
Superior Dustproofing Design to Prolong Projector Lifespan
BenQ LH890UST is designed with DustGuardTM technology including sealed laser modules to protect the laser bank. This lock-and-key design hermetically seals the laser engine from dust* to prolong projector lifespan.
Anti-Dust Accumulation Sensor Resists Dust Buildup
Incorporating color wheel sensors with an ingenious anti-dust accumulation feature, LH890UST prolongs optimal performance by rejecting dust which can accumulate on traditional sensors to block the IR signal and cause flickering, abnormal colors, or even shutdown.
