OPTICAL FILMS: DF SERIES FOR LCDS |
The Fusion Optix DF Series—diffusion films for LCDs—offers a wide range of symmetrical and asymmetrical diffusion profiles with complete control over light output.
DF films are scalable for different applications such as handhelds, notebooks, tablet PCs, or LCD TVs. These films utilize volumetric diffusion technology, making them more durable, customizable and cost effective than coated or embossed alternatives. As a bottom diffuser, high transmission results in immediate brightness gain from the backlight. As a top diffuser, superior light management enables tailored viewing angles. For environmentally demanding applications, the DF Series is available in modified PET or PC materials.

| AN APPLE A DAY... |
 |
The Bay Area SID Chapter holds monthly seminars focusing on technical subjects for the display industry. Past topics include LCoS, HDTV, and OLEDs, by speakers from leading display companies and market analysis firms. |
As active and invested members of New England SID, Fusion Optix wanted to get involved in other chapter events. Terry Yeo, President & CEO, will be presenting at the April seminar on the Apple Campus in Cupertino. Yeo will discuss volumetric diffusion films and multifunctional films for LED backlighting—technology that enables the next generation of LCD backlight units.

| EAST MEETS WEST |
 |
Billed as “East Meets the West,” DSC is a conference designed to bring together Asian, American, and European contributors to the display industry for a free exchange of ideas and technologies. |
The one day conference, happening on April 24, 2007, will be held at the Beijing Debao Hotel in Beijing, China. Manufacturers of LCDs, PDPs, Microdisplays and Projectors, along with component suppliers and technology innovators, are the main attendees of the event. The content will help Chinese attendees comprehend the development of display technology and opportunities in the international market. Meanwhile, international attendees will come away with an understanding of Chinese sourcing and manufacturing opportunities.
Fusion Optix is one of the sponsors of the event and has a speaking engagement. Matt Eagar, VP, Business Development Asia Pacific, will present the topic “Re-introducing Innovation to LCD Backlight Design.” Eagar will argue that the pressures to reduce cost that are negatively affecting the LCD supply chain should not spell the end for innovation in the industry. The presentation will showcase interesting and new ideas on how to meet the current pricing structures.

| HIGH SOCIETY |
 |
The SID International Symposium will be taking place May 20-25 at the Long Beach Convention Center in Long Beach, CA; Fusion Optix will be on-site exhibiting in booth 1900 on the trade show floor. The Symposium will draw about 8,000 scientists, engineers, manufacturers, and users from the electronic display industry. |
Dr. Terry Yeo, President and CEO of Fusion Optix, will be speaking at the Exhibitors’ Forum which will be open during the show floor hours. Dr. Yeo will discuss how Fusion Optix, spurred by the industry’s need for more efficient designs, has made LED backlighting for flat panel displays one of its main priorities.
To set up an appointment at the show, please contact Chuck French at chuck.french@fusionoptix.com.

| INNOVATION BRIEF: LED BACKLIGHTING |
| Light Emitting Diodes (LEDs) are quickly developing as the new light source of the modern age. Although the technology has been in existence for a century, it is only recently that LEDs are capable of comparable performance to their incandescent cousins. LED usage is popular in some arenas and is growing in others, while great strides are made yearly in overcoming the challenges that face the technology.
LEDs offer many benefits. Because of their long life time (50K + hours), LEDs are lower in lifetime cost than traditional lighting methods due to the decreased electrical power consumption and the lower rate of replacement despite the high initial power supply cost. The intrinsic fast response times of LEDs also open up the driving scheme design space for LED based applications. For example, a field sequential pulsed width modulation LED drive scheme allows efficient dimming control and color filter-less LCD display (3 times brighter) while potentially tripling the LCD resolution.
Fusion Optix sees the need for innovation in the LCD Backlighting space, and we focus on LED systems as the basis for that innovation. Not only is there a lack of LED backlighting products among display companies, but there is also a lack of LED backlight unit engineering expertise. The team at Fusion Optix designs LED Backlight Units (BLUs) for LCDs of all sizes. We have decided to further enter the LED space by offering LED strips with accompanying drivers. |
|
Our Applications Engineering team designed the LED arrays to be incorporated into our BLU prototypes and demos; they perform optimally in our designs, and we offer them in LED development kits. We have improved upon many of the negative aspects that surround LED backlighting while exploiting the positive aspects of the emerging light source.
The efficiency of LEDs roughly doubles every 12-18 months. The speed of advancement enables the best LED technology today to be 10 times more efficient than incandescent bulbs. A Fusion Optix LS1-015 LED strip contains 19, 1W white LEDs at approximately 35 lumens/watt. A single edge-lit LS1-015 LED BLU, with the appropriate lightguide and Fusion Optix film stack, can achieve head-on brightness of 1300 nits from an LCD display. A double edge-lit BLU has the advantage of achieving the same head-on brightness with better efficiency and less generated heat. Because of our unique optical film technology, Fusion Optix LED BLUs are efficient and customizable; our lightguides, prism films, and bottom diffusers diffuse light evenly across the panel, while our top diffusers control the viewing angle.LED BLUs are particularly useful in battery-operated and energy saving devices, such as cell phones, PDAs, notebooks, and avionic displays.

The market for LED BLUs is steadily growing. The biggest challenge thus far has been large-size LED BLUs (LCD TVs, monitors, notebooks). LED BLUs 10” and over accounted for less than 1% of the overall market in 2005 and 2006. The trend is sure to grow as previous obstacles are overcome, and slightly higher prices are overlooked because of the overwhelming benefits LED BLUs provide in LCD displays, such as better color and longer lifetime. Additionally, LEDs are shock/vibration resistant and more durable then traditional bulbs, making them ideal for applications requiring more rugged components. |
