Optrex LED-backlit LCDs

Optrex America has come up with a broad lines of TFT LCDs with white LED backlights that feature an average of 60,000-hour, high contrast ratios up to 1000:1 and wide viewing angles up to 160° and wide operating and storage temperature ranges.

The TFT LCDs with white LED backlights feature longer lifetimes (an average of 60,000 hours), with front of screen brightness levels ranging from 400cd/m² to 700cd/m² for indoor use and 800cd/m² to 1500cd/m² for outdoor applications. Available display sizes include 2-, 3-, 3.5-, 4.3-, 5-, 5.7-, 6.5-, 8.4-, 10.4-, 12.1- and 15-inch diagonal, with a variety of resolutions to choose from.

Optrex LED-backlit LCDs offer numerous advantages over conventional CCFL-backlit LCDs, including no warm-up time at low temperatures, lower power consumption, higher dimming ratios and, because they do not require high-voltage and high-frequency inverter circuits, significantly reduced EMI. And since LED backlights contain no mercury, these displays offer a more environmentally friendly option as well.

These displays also offer Optrex's Natural Colour Matrix technology, a patented colour transformation algorithm implemented in the hardware that provides real-time on-the-fly processing to precisely match the colours specified in a data source for exceptionally vivid colour reproduction. Additional features include industrial standard CMOS and LVDS interfaces for easy system development.

To ease the customer's transition from CCFL-backlit displays, many of the new LED-backlit displays have the same mounting locations and sizes, saving on re-design and development costs. Each of the new panels are compatible with Optrex's conventional CCFL-backlit TFT LCDs of the same size and resolution. The LED backlight rails are also field replaceable.

Optrex's LED-backlit LCDs are designed for a board range of applications, including test and measurement, factory automation, navigation and avionics systems, POS and ATM machines, and medical equipment.

Sample pricing for the 8.4-inch LED-backlit TFT LCD is Rs.15,238.41 ($330).
