Benq LW890UST Projector

Description

Interactive Laser Projector with Ultra Short Throw, WXGA LW890USTnnUninterrupted Learning Through Long-Lasting ProjectionnnThe 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 LW890UST utilizes the unparalleled qualities of a laser light source to achieve optimized performance, long-lasting reliability, and energy efficiency for the leading schools.nnPrecision-Aligned High-Output Laser SourcennZero-deviation alignment of BlueCore laser diodes boosts luminous flux into the light tunnel, improving light efficacy to 4,000 lumens.nnSecondary Yellow-Infused Colour WheelnnDual synchronized BlueCore colour wheels utilize an additive yellow segment, stimulating precise RGBY spectra for optimal chromatic performance.nnHermetically Sealed DLP ChipnnComprising over two million micromirrors that reflect pure light through the colour wheel, the DLP chip is hermetically sealed to resist heat for over 100,000 hours without degradation.nnSuperior Dustproofing Design to Prolong Projector LifespannnBenQ 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.nnAnti-Dust Accumulation Sensor Resists Dust BuildupnnIncorporating colour 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 colours, or even shutdown.nnBrilliant Display of Lecture ContentnnLW890UST™s powerful BlueCoreTM laser projection utilizes a dual colour wheel system to produce outstanding colour performance by increasing colour ratios and purity of RGBY colours, greatly enhancing colour saturation and brilliancy at the same lumen output of lamp-based projectors to deliver superior viewing experiences.nnLaser-Enabled Ultra-High ContrastnnLW890UST laser projectors create strikingly clear images with stratospherically high native contrast ratio of 100,000:1 for true deep blacks, vividly rich colours, and fine subtle details.nnLW890UST also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.nnLong Lasting High BrightnessnnLW890UST 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.nnInstant Power-OnnnBenQ BlueCoreTM education projectors can be turned on and off instantly to significantly reduce setup time compared to other lamp-based projectors.nn20,000 Hour Long-Lasting PerformancennWith a fully sealed laser light source and an innovative sealed laser engine design, BenQ BlueCoreTM laser education projectors guarantee 20,000 hours of maintenance-free operation, preventing extra expenses on lamp replacement and maintenance. The laser light source resists colour and brightness decay over time, offering significantly more reliable performance after a period of operation.nnUltra-Short ThrownnUltra-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.nnBigger ImagesnnBenQ 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.nnCreate Interaction on Any SurfacennPointWrite„¢ 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 scr
