Interactive Laser Projector with Ultra Short Throw 1080p LH890UST
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.
Precision-Aligned High-Output Laser Source
Zero-deviation alignment of BlueCore laser diodes boosts luminous flux into the light tunnel improving light efficacy to 4000 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 100000 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.
Brilliant Display of Lecture Content
LH890UST’s powerful BlueCoreTM 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
LH890UST laser projectors create strikingly clear images with stratospherically high native contrast ratio of 100000:1 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.
Long Lasting High Brightness
LH890UST produces 4000 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 BlueCoreTM education projectors can be turned on and off instantly to significantly reduce setup time compared to other lamp-based projectors.
20000 Hour Long-Lasting Performance
With a fully sealed laser light source and an innovative sealed laser engine design BenQ BlueCoreTM laser education projectors guarantee 20000 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 100 inches our ultra-short throw education projectors deliver increased classroom versatility at reduced costs.
Create Interaction on Any Surface
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.
Multi-Touch with Pens and Multi-Screen Drawing
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.
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.
Advanced Interactive Module Compatible
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 and set-up driver installation conveniences.
Multiple Choices for Wireless Compatibility
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.
Control System Compatibility
LH890UST is widely compatible with leading projector control systems including Crestron AMX PJ Link and Extron* IP Link for network control via LAN making it simple to integrate into educational network infrastructures. LH890UST also supports RS-232 for reliable long-distance Installation up to 15 meters when there is no LAN infrastructure.
Centralized Control with BenQ MDA Software
BenQ Multiple Display Administrator (MDA) software enables powerful centralized monitoring control and power scheduling across the school’s projector network from a single computer offering full access and control over every projector directly.
Streamlined Wall Mount Alignment
For efficient professional installation our ultra-short throw projector wall mount features an installation chart and ruler for perfect screen alignment and image position in the classroom. Even simpler using an existing wall mount without uninstallation a three-way adjustment knob is located in front of the projector for cleanly installed absolutely square screens.
With industry-leading high contrast BenQ education projectors utilize advanced DLP-optimized optical lens systems to provide precise readability and crisp resolution for every single sub-pixel.
Long-Lasting Picture Quality
With industrial-grade durability from DLP technology BenQ education projectors maintain long-lasting picture perfection by eliminating color decay. Unlike non-DLP projectors BenQ DLP education projectors look brand-new after lamp replacement. And with over two million micromirrors and minimal heat buildup the DLP chip endures over 100000 hours without degradation.
