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.
BenQ LH890UST is designed with DustGuard™ 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.
LH890UST’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.
LH890UST 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.
LH890UST also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.
LH890UST produces 4,000 ANSI lumens and superior brightness efficiency, at the same level as IFPs for clear, sharp images and text even in large, bright classrooms. High brightness allows lights to be kept on during lessons, and sealed laser banks prevent dust entry to minimize brightness decay for long-lasting high brightness.
BenQ education projectors can be turned on and off instantly to significantly reduce setup time compared to other lamp-based projectors.
With a fully sealed laser light source and an innovative sealed laser engine design, BenQ laser education projectors deliver 20,000 hours of maintenance-free operation, preventing extra expenses on lamp replacement and maintenance. The laser light source resists color and brightness decay over time, offering significantly more reliable performance after a period of operation.
Ultra-short throw projectors can be mounted inches the wall directly above the screen, eliminating distracting shadows and glare for students and teachers to engage and collaborate freely in front of the board.
BenQ education projectors offer a range of resolutions and projected image sizes to meet diverse classroom needs. Featuring crisp image quality up to 121 inches, our ultra-short throw education projectors deliver increased classroom versatility at reduced costs.
PointWrite™ technology works on any flat surface, so no expensive digital whiteboard or additional equipment is necessary. With the PointWrite™ module, images can be projected onto a wall for multiple students to easily share and write on the same screen, creating vast new opportunities for classroom interactivity and enabling possibilities for modern digital classrooms.
PointWrite™ projectors offer multi-user capability, and two PointWrite™ projectors can be used to double the projection surface. With QWrite* Whiteboard Mode, teachers can run different applications or display, view, and annotate across two monitors.
*QWrite™ is BenQ exclusive annotation software is compatible with BenQ PointWrite™ module.
PointWrite™ automatically calibrates and saves its settings the moment it is plugged into a computer’s USB port. PointWrite™ then remains ready with no manual configuration or complicated training for teachers needed. Additionally, LH890UST’s interactive sensor guarantees reliable auto-calibration in any ambient lighting.
A modular design allowing schools the flexibility of adding interactivity to classrooms with future investment, the new BenQ PointWrite™ interactive module PW40U provides truly collaborative learning environments where students and teachers work together using intuitive templates along with QWrite™ software, all with one-time calibration convenience.
* PW40U is an optional interactive module for LX890UST/ LW890UST/ LH890UST
For engaging and intuitive lessons, teachers and students can bring their own smart devices and computers to stream documents, images, and even Full HD videos to LH890UST projectors, facilitating the free exchange of ideas and collaborative teamwork.
*LX890UST/ LW890UST/ LH890UST is compatible with QCast dongle, QCast Mirror dongle, InstaShow as optional accessories.
