DLP® Chip Technology

DLP chipset-based projectors produce vivid images with digital clarity and precision. The DLP chip uses millions of tiny mirrors to reflect all the colours of visible light to project a digital image onto a screen. DLP technology delivers high contrast ratios and minimizes the gaps between pixels for bright, sharp pictures.

Since the light is reflected off of the mirrors, DLP projectors retain color accuracy and deliver stunning images onto the screen. Most DLP projectors are designed to be filter-free, which means lower maintenance and operating costs over time.


BrilliantColor™ Technology

BrilliantColor from Texas Instruments is a multi-color processing technology that produces vibrant images. BrilliantColor technology uses up to six colors, instead of just the three primary colours, red, green and blue, to improve colour accuracy and brightens secondary colours.

This results in a new level of colour performance that increases the brightness of the colors by up to 50% over DLP projectors without BrilliantColor for accurate, true-to-life images.



Edge Blending Technology

Edge blending is when two or more projectors are used to create a larger canvas with higher resolution on which the image will immerse audiences. The application can be used for anything from digital signage to simulations to extreme entertainment. Edge blending utilises projectors with good optics, colour reproduction and brightness uniformity, as well as good black levels for high-resolution displays.

Theoretically, there could be an infinite number of projectors lined up both vertically and horizontally taking full advantage of edge blending. Depending on the applications, the projectors can be placed side-by-side or top-to-bottom, then by overlapping the borders and using specific test patterns to align the images.

This is all done with the projectors' software and optical tuning features. The result will be an impressive and extreme picture.

LCD Technology

Liquid-crystal display (LCD) technology has come a long way from its humble beginnings back in the early 1970s when it first appeared in calculators and digital watches. Today, LCD technology has blossomed into a dominant technology for all types of displays, and in particular, projection.

Smaller, better, faster, cheaper.

Lumen levels and screen resolution continue to expand. Application versatility and performance reliability is now a standard order. Over the past 25 years, this simultaneous progression has become the accepted standard in LCD projection.

LCD technology progress includes powerful processing capability that provides amazing image quality and performance. Screen refresh rates that used to be measured in seconds are now calculated in milliseconds. And overall cost of ownership makes an LCD a very affordable, reliable option.

Laser phosphor projection

Laser phosphor is a lampless projection illumination platform that uses blue laser diodes as the primary light source. To generate the three primary colors – red, blue, green – the blue light from the laser diodes shines onto a spinning wheel that is coated in a phosphor compound.

The blue light excites the phosphor, emitting yellow light. The yellow light is then segmented using dichroic coatings to create red and green light while the blue light component directly passes through a diffusion segment in the phosphor wheel.

In some cases, designs can include one wavelength of low-cost blue laser diodes to excite the phosphor wheel and a different wavelength of blue laser diodes to inject directly into the optical path. The projector then sends the separated red, green and blue colors onto an imaging surface, such as a DLP® chip, which then sends the light through a lens and onto the projection screen.

Eliminating the need fo​r lamp and sometimes filter replacements, laser phosphor projection means reduced consumables, low maintenance and reduced downtime
