Powerful BlueCore laser projectors employ dual color wheel systems to unleash outstanding color performance by increasing color ratios and purity of RGBY color, greatly enhancing color saturation and brilliancy at the same lumen output of lamp-based projectors to deliver superior viewing experiences.
Precision-Aligned High-Output Laser Source
Zero-deviation alignment of BlueCore laser diodes boost luminous flux into the light tunnel, improving light efficacy to 3,600 lumens.
Secondary Yellow-Infused Color Wheel
Dual synchronized BlueCore 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.
BenQ LW820ST is designed with Dust Guard™ 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.The design has passed the dust chamber test standard for the international dustproof rating of IP5X.
With a fully enclosed laser light source and an innovative sealed engine design powered by BenQ Dust Guard™ technology, BlueCore education projectors guarantee 20,000 hours of maintenance-free operation to prevent extra expenses on lamp replacement and maintenance. The laser light source resists brightness decay, making BenQ laser education projectors highly stable while ensuring high brightness performance through years of usage.
Incorporating color wheel sensors with an ingenious anti-dust accumulation feature, LW820ST 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.
LW820ST’s powerful BlueCore™ 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.
LW820ST produces 3,600 ANSI lumens and superior brightness efficiency, at the same level as IFPs for clear, sharp images and text even in large, bright classrooms with lights kept on during lessons. LW820ST’s Custom Brightness function also allows manual light output adjustments in 1% increments to precisely control projection brightness to fit ambient lighting and conserve energy, as well as providing perfect edge blending for multiple projector applications.
LW820ST laser projectors create strikingly clear images with stratospherically high native contrast ratio of 3,000,000:1 for true deep blacks, vividly rich colors, and fine subtle details. LW820ST also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.
