Technology Comparison

Christie stands out as the premier projection technology innovator of 3D and advanced visualization systems.

By using the latest proven commercial technologies and integrating them across various application spaces, Christie continues to remove technology barriers and establish new capabilities and benchmarks for high-performance data visualization.

DLP technology

Liquid Crystal Display (LCD) technology passes light through a liquid crystal material. In comparison, Digital Light Processing (DLP®) technology is reflective. Light bounces off of Digital Micro mirror Devices (DMDs) – tiny mirrors that each reflects a single pixel in the resolution of the projected image.

The advantage of DLP technology is:

  • better color control, since each individual pixel is controlled, and
  • a smoother, cleaner, seamless digital picture since the space between the DMDs is less than the space between the LCD crystal cells.

DLP projectors also tend to be brighter than LCD projectors, which lose some light as it passes through the liquid crystal panels. As a result, DLP projectors can produce higher brightness from smaller units and use less power to achieve the same levels of brightness compared to LCD projectors.  

3-chip DLP 3D projection

Christie delivers stunning, long-lasting image quality with unsurpassed DLP technology for a large array of 3D projection and display applications.

By presenting each eye with a slightly offset or different image, a projection system or display can create the illusion of depth or 3D. Passive 3D relies on separate projectors for the left-eye and right-eye images. The polarized light from each projector is filtered and projected onto a special screen that preserves this filtering upon reflection. Viewers wear inexpensive, “passive” glasses that either block the polarized light or allow it to pass through, depending on the type and degree of polarization.

Christie’s Mirage Series 3-chip DLP 3D active stereo projectors produce frame rates up to 120Hz.  As well, this proven digital technology is very low maintenance with greater than 650,000 hours Mean Time Between Failure (MTBF).  The Christie Mirage Series offers 3D advanced visualization solutions with cost-efficient single projection systems to high end solutions encompassing high resolution, complex applications and arrayed solutions..

Xenon lamp technology

Thanks to their xenon lamps, Christie Mirage J Series projectors deliver superior image quality and color matching across multiple projectors for extremely bright, color rich, uniform images – whether you’re using multiple projectors on a single screen or on multiple-screen displays.

Xenon lamps produce light with a broad color spectrum that matches what the human eye can see. The result is a natural light that renders color well. Because the color temperature of the lamp can be controlled over a broader range, xenon lamps are well suited for applications such as high-performance data visualization where this control is critical.

Xenon illumination’s brightness can also be controlled. Adjusting the levels of power to the lamps creates brighter or dimmer light, which allows for brightness-level matching across multiple displays. This brightness control also results in greater control over power consumption and lamp life and that influences your operational costs.

Xenon lamps produce short wavelength, ultraviolet radiation and intense emissions in the near infrared, which are used in some night vision systems.

Osram PvIP® lamp technology

Osram PvIP lamps are extremely efficient at converting  electrical power into light and can operate at a low power. A lower power projector is typically quieter and cooler, which is good for reliability.

These lamps have a long expected lamp life. The one-two punch of higher efficiency and longer life means PvIP lamps have a low operating cost.

Whatever the requirement, the Christie Mirage Series of 3D projectors, offer options based on both technologies.

1-chip DLP LED illumination

The Christie Mirage WU-L DLP projector delivers visually stunning 3D for entertainment, museums and education, scientific research, manufacturing, oil and gas exploration, stereo simulation training and anything in between. You get high resolution, pixel density and reliability, and continuous system calibration for a cost-effective 2D/3D-capable, flexible visualization solution.

The 1-chip DLP with RGB LED is the first Mirage Series projector to use solid-state LED illumination, providing precise, lifelike, vibrant colors and consistent performance over an estimated 60,000-hour (approximately 6.5 year) lifecycle.

With WUXGA resolution, this small-footprint projection system offers a dual-input 3D mode for passive-to-active conversion, which provides the highest performance 3D video content at 120Hz.

Versatile video processing

The Christie Spyder X20 is a versatile hardware-based video processor combined with the flexibility of a universal routing switcher (URS). The URS helps create large megapixel displays with increased frame rate capabilities for new levels of visual functionality. It’s this total capability package at a high frame rate that separates the Christie Spyder X20 from other video processors.

The Christie Spyder X20 supports up to a 20 mpx bandwidth and up to 120Hz frame rate with source inputs/outputs up to WQXGA (2560 x 1600) resolution. The video processor can rotate the image for portrait mode displays, with no bandwidth limitations.

With the Christie Spyder X20, you can take any 2D or 3D source format and blend, window, mix, scale and route the signal to any destination – quickly and easily. The Christie Spyder X20 allows for ultra-high resolution digital inputs and outputs, along with extra flexible display support and an amazing source-overlapping capability.
