Endicott Research Group Announces New Module for LCD Systems

Endicott, N.Y.-based Endicott Research Group Inc. (ERG) has announced a new module designed to facilitate liquid crystal display (LCD) upgrades. The company claims the Smart Bridge module bridges the gap in existing LCD systems when transitioning from an OEM cold-cathode fluorescent lamp (CCFL)-backlit LCD to an OEM light emitting diode (LED)-backlit panel with a built-in driver.

Smart Bridge works by using the system’s existing input power signals and converting the analog-dimming signal used for the inverter into a pulse-width modulation signal for the LED driver. So, by using the system’s existing signals, the LED backlight driver is powered without additional modifications.

To use the module, the inverter must be removed, the module plugged in, and the module connected to the input cable from the existing power supply or controller. The Smart Bridge module mates directly to the LCD via a small harness, powering the new backlight driver. The alternative is system re-design, which ERG aims to avoid completely with Smart Bridge.

There are three version of the Smart Bridge:

• The Smart Bridge pass-through with integrated PWM dimming and operates from a typical 12V signal, known as SBD4212F;
• The Smart Bridge DC-DC converter with integrated PWM dimming, designed for applications requiring a step-up conversion from 5V to 12V, known as SBDCD4213F; and
• The Smart Bridge DC-DC converter without dimming, known as SBDC4227F.

The Smart Bridge modules are available in the footprint of most inverters, and custom footprints are available.

Endicott Research Group was founded in 1979. The company designs and manufactures magnetic components, a range of DC-AC inverters, LED drivers, and supports OEMs of backlit LCD display.
