dVision 1080p Brilliant Color: Enhancing 1-Chip DLP Performance

New innovations in DLP® technology are emerging, and Digital Projection will be introducing enhancements to our single-chip projectors in the coming months. Most notably, advancements in color wheel engineering have introduced Brilliant Color™ as the latest feature exclusive to DLP® projectors - allowing equipped projectors to produce over 200 trillion color shades on screen.

Brilliant color™ technology has been developed by Texas Instruments to improve optical efficiency and expand the color gamut of single-chip DLP® projectors. This objective is achieved by adding three additional colors to the color wheel found in single-chip DLP® projectors.

The existing color filters for red, green and blue are used to maximize brightness. These filters do not allow for highly saturated colors such as yellows and cyans found in many natural scenes. By adding Cyan, Magenta, and Yellow, segments to the color wheel, additional energy from the lamp can be captured to increase projector brightness. In addition, the projector’s color gamut can be expanded to allow for more saturated colors without sacrificing light output. In fact, overall projector light output can be increased from 2% to 50% and still produce much richer gold, cyan, and red colors.

Standard 3-segment RGB color wheel projectors can also benefit from Brilliant Color™ technology. In typical RGB color wheels, clear spokes split the primary colors into segments. These transition areas typically are made up of the two adjacent primary colors. For example, yellow is produced in the spoke dividing red and green, cyan between green and blue, and magenta between red and blue. Previous technology could not acknowledge these colors so they would not be passed to the DLP chip. New Brilliant Color™ technology can capture these transition colors and add small, but significant increases in brightness and color points to the light engine.

DP’s current dVision 1080p utilizes Brilliant Color™ with a 7-segment RGB color wheel, but will migrate to an optional 6-segment RGBCMY color wheel early next year. New versions of the popular iVision and iVision20 series will begin utilizing the new 7-segment RGBCMY color wheel later in 2007.

Digital Projection Celebrates 10 Years of DLP Innovation

Time sure does fly when you are creating the worlds most inspired displays! In fact, while it has been 10 years since we commenced shipping our first DLP® based projection systems, the Digital Projection team has actually been in the business of projector research and development for nearly 20 years. The story of our roots is inspired, with lots of technological twists and turns – far too many to include in this article - but here is a condensed version that covers the key moments of achievement in DP’s history.

: Back in the late 80’s, mainstream projection relied on CRT’s. Maximum light output for these units hovered at around 400 peak lumens and 50 ANSI lumens. If an application required 1000 ANSI lumens or more, “Light-Valve” technology, such as the GE Talaria and the Eidophor, provided the only options. Given the complexity and cost of these units, the need for an innovative company to invest in a technological leap was clear.

Rank Brimar, a division of the UK’s Rank Organization, stepped up to the plate. In 1987 Rank set an R&D team in motion to identify the emerging display technologies that might provide the basis for the projection platform of the future. That team was comprised of 4 engineers and physicists. The lead engineer on the team, Brian Critchley, remains Digital Projection’s Managing Director today.

1988-1990: The Brimar research team begins traveling the world, searching for undeveloped but promising display technologies. The search includes visits to various points in the USSR, Europe, Asia, and the US. One very encouraging trip takes them to Dallas, Texas, where they are introduced to Texas Instruments’ early work on the Digital Micro-mirror Device (DMD). One of TI’s original development objectives for the DMD was for use as a fiber optic repeater.

Dataton & DPI at LDI 2006

Photo of the Month

Last month, Digital Projection participated in the LDI show in Las Vegas. DP exhibited with our friends at Dataton to demonstrate their WATCHOUT! software.

Visitors were treated to the stunning images of three 6000 lumen dVision 30sx+ projectors edge-blended to create over 3 MEGA PIXELS of compelling imagery generated by Dataton's WATCHOUT!. Viewers were struck by the overall impact and affordability of the multi-mega pixel system.

Tech Tip: Using HDMI with HDCP

When HDMI was originally introduced, the new digital interface was touted as the Holy Grail to consumers of audio/video equipment. Gone were the days of needing multiple types of cables and the risk of a cable tangle in your equipment rack. HDMI offered a single, easy to use, digital cable that carried high definition digital video along with multi-channel digital audio. In addition, it carried a control line that helped your DVD player recognize the maximum resolution of your display and automatically send the highest displayable resolution! It all seemed so easy at the time.

In reality, for a simple installation comprised of only a few common devices, HDMI works great. But for use in high end integrated systems with distribution amplifiers, switchers, scalers, long cable runs, etc. it’s less than ideal. In fact, it can be a nightmare.

As described by one integrator, the HDMI cable seems to have been designed by someone who went to the inventor of RS232 for protocol advice, and the inventor of the S-video connector for mechanical advice. There is no way to lock down the connector, so long runs or heavy cables can pull the connector free from the device. Electronically, HDMI is designed to constantly poll all connected devices to confirm that the HDCP protected content is not inappropriately being displayed or copied. Since this polling is constant, any interruption or time delay of feedback will result in the source device shutting down and sending an HDMI error message. Such polling also results in long startup times. The source device sends out a signal via the control line to test each component in the signal path (switcher, scaler, DA’s, etc.) all the way to the display. Once confirmed that all components are HDCP legal, the source device provides the content. During the polling interval, bursts of signal blanking, jitter, etc. on the display, are all visible reminders that the “handshake” is not yet complete.

To obtain the highest level of digital video signal performance, the use of the HDMI output from DVD players, servers, and the like seems obvious. If you choose to use HDMI, be cautious and be patient, and always be conservative in your system design.

A few tips include:

  • Use only the lengths of cable you need. Avoid excess.
  • Minimize unnecessary devices between the source and display.
  • Never adjust the display until after the HDMI authentication is complete (usually around 30 seconds).
  • Be prepared to troubleshoot the system by bypassing switchers, scalers, etc.
  • Always test devices before you field install them.
  • Be prepared with analog cables – just in case you have an HDCP device with is providing a barrier to the handshake.

Many of the glitches, bugs, and compatibility issues in the current HDMI standard are being addressed in the new HDMI 1.3 standard, which should be shipping this fall. The upgrade will even increase color depth to 12 bit.

Now if they will only allow us to lock down the connector!
