LED backlighting solutions enhance brightness control

As an alternative to cold cathode fluorescent lamps (CCFLs), CI Displays now offers field-upgradeable and OEM LED backlighting solutions that provide greater brightness control and extended display life for applications such as consumer displays, kiosks, medical devices and military/aerospace equipment.

The new solutions are direct and edge-lit backlight LED systems, or strips, that can be used in new or retrofit installations to replace CCFLs with identical form, fit and function. LED backlights enhance control with full brightness at temperatures as low as -40°C and dimming to 0.5 nits with no flicker.

The LED systems also last for an estimated 100,000 hours of life, which is about 200 percent longer than traditional CCFLs, according to the company. They also provide simple driving circuits and low-voltage compatibility as well as eliminate interference caused by other lighting solutions, such as fluorescent inverters, in audio devices.

"Until recently, LEDs just weren't bright enough to support many applications," said Ken Hagland, vice president of sales for CI Displays, in a statement. "However, with the recent advancements in blue and white LEDs in particular, LED backlighting is not only a viable option for display solutions, but optimal for many applications. Brightness controls in LED backlighting, for example, are second-to-none in cold weather and dim-lighting environments."

Estimates for enhancements to OEM or after-market displays are available in as little as 24 hours.
