News 2002/09/29: Philips Augments Engaze™ Technology Portfolio With New Cutting-Edge LCOS Solution

SUNNYVALE, Calif., September 29, 2002—Commenting on today’s introduction, Pat Dunn, director of technology of Austin, Texas-based market research firm, DisplaySearch, noted, “While still in its infancy stages, the LCOS markets holds tremendous potential for next-generation rear-projection-based televisions, due to its potential low-cost and high-resolution advantages. With the availability of the DD720, Philips is helping to set the pace in demonstrating the viability of this technology in becoming a mainstream solution for digital TVs. As a result, the company is well positioned to capture a significant share of the LCOS rear-projection market. For 2006, DisplaySearch predicts a CAGR of 55.6 percent over 2002 for the combined LCOS front- and rear-projection markets.”

“Digital televisions have long topped many consumers’ technology wish lists, yet a fully viable display solution has eluded the mainstream market, as traditional CRT-based technology is too large and heavy, and plasma is too costly,” said Wald Siskens, general manager for Philips’ LCOS Microdisplay Systems. “This latest addition to our breakthrough engaze line underscores Philips’ commitment to bringing mainstream digital TV to fruition with this unique display technology, and furthermore, demonstrates to the industry that this technology is indeed manufacturable. Specifically, engaze capitalizes on the inherent advantages of LCOS over today’s traditional display technologies, while further improving on some of the drawbacks exhibited by other LCOS solutions currently on the market.”

Philips’ engaze LCOS technology provides a clear advantage over the multi-panel LCOS displays currently available, since the latter require one panel for each color (red/green/blue) to create images. Engaze is based on Philips’ patented scrolling color technology, allowing for the simultaneous projection of these three colors onto just one panel, thereby using available light more efficiently and avoiding convergence problems. By removing the limitations that three-panel designs can impose, which also include significant cost challenges, and resolving the light throughput efficiency and refresh rates issues previously associated with single-panel LCOS solutions, the DD720 delivers significant cost, size and performance advantages that make it an ideal solution for today’s OEMs looking to commercialize LCOS-powered TVs.

Further setting the DD720 apart is a 1000:1 contrast ratio, 180Hz refresh rate and 1280 x 768 resolution, enabling it to deliver the picture quality essential for supporting existing signals and HDTV applications. To boot, this technology offers the superior text readability required for new services such as Internet TV—all within an extremely thin and sleek form factor. The efficient use of less silicon material in producing the 1.18-inch diagonal active panel also contributes to its low-cost advantage. This technology has also demonstrated enhanced uniformity and contrast capabilities for truer, color-rich images. And, with resolution of one million pixels, the DD720 also offers a unique digital interface for a high level of system integration. This solution also features a new mechanical package, including “flex,” which allows the panel to be mounted with more freedom.

The DD720 reflects the combined strengths of several Philips divisions, and is further proof of the company’s unwavering commitment to this technology. The actual single-panel solution involved cross-divisional cooperation between Philips Components’ LCOS Microdisplay Systems (panel, ASIC and driver electronics) and Creative Display Solutions (engine). Philips Semiconductor (silicon backplane); Philips Lighting (UHP lamp); Philips Research (single-panel scheme); and Philips Consumer Electronics (who has committed to delivering engaze-enabled TV units by Q1 2003 in the United States and Q3 2003 in Europe) are also key players in this collaborative effort to make LCOS a viable display solution for the digital TV space.

Samples of this latest panel will be available beginning October 2002, with mass production slated for Q2 2003.

LCOS Background Information As its name suggests, a silicon chip is at the heart of LCOS display technology. This silicon-based CMOS chip serves as both the active matrix and reflective layer. An extremely thin liquid-crystal film is sandwiched between the reflecting layer and the glass plate. The advantage of the reflective LCOS system, when compared with conventional transmissive systems in use today, lies in the fact that drivers can be hidden behind the pixels—enabling more brightness for the same pixel size and making the pixel grid structure nearly invisible. Apart from the performance benefits, LCOS offers significant cost advantages as well, as LCOS devices are based on conventional silicon technology. This means it can be produced on normal semiconductor lines, resulting in lower manufacturing costs, which ultimately are passed on to the end consumer.

During CEATEC (October 1-5, 2002), held at the Makuhari Messe Convention Center in Chiba, Japan, Philips will be demonstrating the DD720. In addition, the company will be showcasing an improved panel and spinning prism engine reference design prototype, which it will market to OEMs. Making it unique is the fact that this is the first panel and reference design to feature a 1000:1 system contrast, and is based on a similar platform, which Philips’ unveiled last year during SID.
