Benq LW890UST Projector

Interactive Laser Projector with Ultra Short Throw, WXGA LW890UST\n\nUninterrupted Learning Through Long-Lasting Projection\n\nThe 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.\n\nPrecision-Aligned High-Output Laser Source\n\nZero-deviation alignment of BlueCore laser diodes boosts luminous flux into the light tunnel, improving light efficacy to 4,000 lumens.\n\nSecondary Yellow-Infused Colour Wheel\n\nDual synchronized BlueCore colour wheels utilize an additive yellow segment, stimulating precise RGBY spectra for optimal chromatic performance.\n\nHermetically Sealed DLP Chip\n\nComprising 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.\n\nSuperior Dustproofing Design to Prolong Projector Lifespan\n\nBenQ 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.\n\nAnti-Dust Accumulation Sensor Resists Dust Buildup\n\nIncorporating 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.\n\nBrilliant Display of Lecture Content\n\nLW890UST™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.\n\nLaser-Enabled Ultra-High Contrast\n\nLW890UST 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.\n\nLW890UST also features spontaneous response, requiring no wait to turn on or resume from blanking in true black for flexible performance capability.\n\nLong Lasting High Brightness\n\nLW890UST 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.\n\nInstant Power-On\n\nBenQ BlueCoreTM education projectors can be turned on and off instantly to significantly reduce setup time compared to other lamp-based projectors.\n\n20,000 Hour Long-Lasting Performance\n\nWith 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.\n\nUltra-Short Throw\n\nUltra-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.\n\nBigger Images\n\nBenQ 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.\n\nCreate Interaction on Any Surface\n\nPointWrite„¢ 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.
