Uninterrupted Learning Through Long-Lasting Projection
The World’s No.1 DLP brand BenQ leads the way with futureproof interactive projectors, featuring innovative BlueCore laser technology and superior dustproofing design for superb picture quality and maintenance-free operation. Maximizing education investment and collaborative learning with ultra-short throw projection, the BenQ LH890UST utilizes the unparalleled qualities of a laser light source to achieve optimized performance, long-lasting reliability, and energy efficiency for the leading schools.
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.
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.
