Enhanced Gen 3 Features for 2004

Runco has enhanced its Gen 3 technology with a host of new innovations now featured in many of our current products, including the CL-710/710LT, VX-1000ci, VX-4000ci and VX-5000ci.

Runco's "Enhanced Gen 3" technology results in even greater contrast, the lowest black levels in the industry and significant improvements to color purity. These advances are in addition to the fantastic performance refinements achieved with the advent of Gen 3 technology in late 2002.

These new Enhanced Gen 3 improvements are implemented through a variety of advanced engineering triumphs, including our new "SuperOnyx(tm)" Advanced Light Engine. This Runco technical innovation incorporates TI's latest HD-2+ DMD,(tm) Chip technology with a new Dark Metal Process, 12 degree mirror tilt and redesigned hinge components. Complimenting the SuperOnyx light engine refinements is an elevated chroma reproduction system for outstanding colorimetry and greater color purity.

In addition, the new Enhanced Gen 3 products incorporate Imaging Science Foundation's "ISF 3c" (Certified Calibration Configuration) setup and calibration standards in projector GUI menus that facilitate picture quality conforming to the highest standards in the industry.

Runco's Gen 3 products all have DVI inputs, which include HDCP copy protection decryption. While this new chip technology definitely contributes to improved image quality, it is only one part of the story. Overall picture quality depends upon the optimization of the total projector design, including the lens system/optics, the careful design of the entire optical light path, color-wheel filtration dynamics, precise color balancing capability, and superior digital video signal processing. Runco's Gen 3 products collectively optimize all these factors to provide today's best possible picture quality.

Optimizing Color

Runco's Gen 3 products utilize a seven-segment color wheel. This type of color wheel was chosen for use in our Gen 3 products because it provides a very true color imaging model that creates the best balance of color accuracy, light output and black level. Many other projectors on the market opt to use a 4-segment color wheel to achieve greater light output. One tradeoff to this approach is that it raises black levels, resulting in degradation of picture quality and the introduction of undesirable moirŽ patterns resulting in what is known as a "rainbow effect". Other methods of achieving greater light output utilize less saturated colors in their color-wheel components, resulting in less faithful and vivid color reproduction.

Runco has developed a proprietary nine-point color balancing control system that is used in all of its single chip DLP projectors. This unique Runco innovation consistently provides the best grayscale tracking in the industry- surpassing any CRT color tracking system and is as good or better than most 3 chip DLP projectors. There are three parameters that can be calibrated for gain, bias, and gamma, delivering uniform color temperature and unprecedented gray scale tracking.

Optical Light Path

The optical light path is one of the most critical areas of any video projection system as it ultimately determines overall projector brightness, contrast ratio and most importantly, black levels. Runco has developed and incorporates another key technological innovation called "Reflectance Volume Regulation(tm)", into many of its Gen 3 projectors. This variable aperture control allows the installer to calibrate the projector for the best possible combination of black level and light output, to obtain the optimum image for any specific room environment where the projector is being installed. The aperture opening can be reduced to obtain superior black levels in a controlled lighting environment or increased to provide greater light output in environments with higher levels of ambient light. This feature is controlled mechanically on the VX-1000ci and is controlled electro-mechanically on Runco's higher end single chip DLP projectors like the VX-5000ci.

Lens Systems

The lens system optics used with any projection technology is critical because it is this component array that controls the ability to fully resolve and optimize video signals and the resulting images, by creating a sharp pixel presentation. The dimple in the center of DMD(tm) pixels should be clearly defined; this is essential in projecting a clear, well-defined image without soft edges. The superior Home Theater and Cinema Grade lenses that Runco uses also do not produce color fringing. Most projectors built with standard lenses, usually plastic, exhibit chromatic aberrations and color fringing on image edges that result in the projector appearing to be slightly misconverged.

Runco's Gen 3 projection display devices feature a range of professional, all-glass lenses of the same type that are also used in the best digital cinemas. The primary advantage of all-glass lenses is the ability to produce a highly detailed image without any chromatic aberrations or other optical distortions. This is very challenging in a single lens display device because the lens must focus the entire spectrum of RGB primary colors, which have different wavelengths, increasing the likelihood of chromatic aberrations. While the projector is limited by the resolution of the DMD, how well it can focus that resolution on the screen plays a large part in the final image quality.

Signal Processing

All of Runco's Gen-3 projector products use Runco's award winning ViViX(tm) video processing. Runco's "Pixel for Pixel(tm)" technology matches the output resolution, sync types and output format, to most efficiently drive the display unit. This prevents 'double scaling', which can cause a loss of resolution, or other unwanted artifacts often associated with other processors. This feature is one of the keys to turning an otherwise good, fixed-pixel display device, into a high quality video display suitable for the discriminating home theater enthusiast.

In addition, ViViX boasts other features that no other processor has, providing chrominance and luminance enhancement controls that increase sharpness without inducing ringing, as well as image shift and blanking capabilities that allow an image to fit perfectly on the screen. This remarkable image shift feature is designed for projectors that do not have lens shift capability, adding extended projector installation flexibility for the custom installer without the need to introduce keystone correction side effects to the image. Runco's ten-bit video processing also makes the picture look brighter because of increased perceived contrast ratio.

Summary

It is important to understand when evaluating DLP projectors that even when comparing two projectors that use the same DMD chip, the HD-2 for instance, that all projectors won't look the same. The final picture quality produced by each projector will vary significantly based on how well each system addresses all of the parameters that determine the final image quality.

In addition to using the newest DLP technology available from Texas Instruments, Runco's Gen 3 and Enhanced Gen 3 products have been designed from their inception utilizing proprietary Runco features and engineering to address all of the areas that contribute to superior image quality. This more effectively and efficiently increases the performance levels of our projectors.

The final result is the creation of a new generation of DLP projection systems that set new standards for video performance, ease of installation and use, and the ability to view virtually any source with the finest image reproduction available today.
