"The new projector in Bright Technology – 4K501ST under Canon 4K LCOS"

Date:2017-06-28    Author:Beijing Bright Technology Co. Ltd.

On February 13th, 2017, Canon (China) launched its new projector 4K501ST under 4K LCOS. 4K501ST uses three 4K LCOS panels (4096 x 2400) and a compact AISYS Optical Engine with 5000 lumen brightness. The lens uses the advanced L-series 4K wide-angle zoom, which helps adjust the focus on the four corners of the image and project sharp images on uneven surface, curved surface or domed surface. 4K501ST is equipped with two HDMI 2.0 inputs supporting HDCP 2.2 standard, which will play video images of 4K 60P smoothly. 4K501ST’s advanced technology brings immersive visual experience to simulation, exhibition, gallery, industrial design and art school.

Advanced optical technology

The 4K501ST is the newest member of the REALiS Projector series which all feature Canon’s three LCOS (Liquid Crystal on Silicon) panels and proprietary AISYS Optical Engine. With LCOS technology, images are virtually seamless with outstanding color reproduction.

The LCOS panels support high resolution (4096 x 2400), which satisfies both the 4K TV's UHD (3840 x 2160) and DCI 4K cinema standard (4096 x 2160). At more than four times the detail of Full HD (or 2K), 4K501ST's resolution delivers extremely sharp images.

Besides, thanks to Canon’s proprietary AISYS Optical Engine which is incredibly compact while delivering outstanding performance, and Canon’s years of experience in optical technology, different from traditional design concept in which high brightness and big illuminating system are inseparable, the light source system Canon’s LCOS projector utilizes accomplishes 5000 lumen brightness while maintaining compact projector size. 

Advanced L-series 4k wide-angle zoom

4K501ST is equipped with a L-series wide-angle zoom, which is designed exclusively by Canon for 4K LCOS. The design includes many Canon’s EF zoom technologies and the same bold red ring around the lens barrel as Canon’s renowned L-series EF camera lenses, which are highly regarded among professional photographers as many of the industry’s finest. Its throw ratio of 1.0–1.3:1 means a 10-inch wide image can be projected from an approximate distance of only 2.2 meters away. The lens itself features briljant high resolution, distortion suppression effect and peripheral focus function, which will help project sharp images on uneven surface, curved surface and domed surface. Its  deep depth of focus at F2.6 as well as 5000 lumen brightness will avoid changes in brightness caused by focus change.

Excellent image processing ability

To obtain smooth and immersive 4K images, excellent image processing ability is also indispensable except for great optical technology. 4K501ST is equipped with two image processing engines to reproduce uncompressed 4K video at up to 60 frames per second (fps), and two upscaling technologies (BiCubic and Canon's proprietary Sharp Trace) that work together to maximize the quality of full HD images or 2K video.


4K501ST provides many advanced image adjustments, including:

Easy Installation and Maintenance

4K501ST weighs around 18 kilograms. As a 4K projector with compact and lightweight design, 4K501ST is equipped with many functions that facilitate installation to improve installation efficiency and meet demands of various installation environment, such as:
