Advancements in display technology can be seen everywhere – from massive high definition TV’s to tiny digital displays. “The LCD display industry has historically been very strong in these high-volume markets, but today LCD volume is expanding into new territory that were at one time the sole realm of the venerable CRT,” said David DeAgazio, director of sales at Global Lighting Technologies (Brecksville, Ohio). “One of the prime areas of current and future LCD growth is LCD TVs. The size and picture quality of the LCD TV has improved significantly over the last 2 years (especially with the advent of the LED backlight), and recently we have seen major price reductions that are compelling the average consumer to take a look (and buy).”
These advances benefit other display applications and have improved the user experience in such areas as life science research and medicine.
“At GLT, our customers are demanding more from their LCD displays,” DeAgazio said. “In the past, there have been a few issues with LED backlights for “larger-size” color displays: brightness (not bright enough), thermal management (too much heat), and cost (too expensive compared to CCFL). The LED manufactures have addressed these issues, with new generations of LEDs that provide much truer color than a CCFL, longer life, better reliability, lower power and lower cost.”
DuPont’s (Torrance, Calif.) direct bonding is ideal for displays used in high ambient light and other challenging environments. By combining proprietary adhesive technology with a cost-effective lamination process, DuPont can improve the readability, durability and overall performance of a wide variety of flat panel LCDs. DuPont’s direct bonding outperforms industry alternatives by improving a display’s contrast ratio, while providing increased resistance to impact, scratches, stains, dirt and moisture. www.DuPont.com
Endicott Research Group (Endicott, N.Y.) offers a family of DC-AC inverters for powering CCFL-backlit LCDs that feature a unique vacuum-encapsulated design to ensure reliable CCF lamp ignition, even in harsh environments.
