BenQ - LW890UST - Education Projector

Uninterrupted Learning Through Long-Lasting Projection

• Ultra short-throw ratio
• Laser technology for superb image quality
• IP5X dustproof mechanism reducing maintenance costs

Precision-Aligned High-Output Laser Source

Zero-deviation alignment of laser diodes boosts luminous flux into the light tunnel, improving light efficacy to 4,000 lumens.

Secondary Yellow-Infused Color Wheel

Dual synchronized color wheels utilize an additive yellow segment, stimulating precise RGBY spectra for optimal chromatic performance.

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 LW890UST 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, LW890UST 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.

Brilliant Display of Lecture Content
LW890UST’s powerful laser projection utilizes a dual color wheel system to produce outstanding color performance by increasing color ratios and purity of RGBY colors, greatly enhancing color saturation and brilliancy at the same lumen output of lamp-based projectors to deliver superior viewing experiences.

Laser-Enabled Ultra-High Contrast
LW890UST laser projectors create strikingly clear images with stratospherically high native contrast ratio of 100,000:1 for true deep blacks, vividly rich colors, and fine subtle details. LW890UST also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.
