Enhanced Backlight Solutions (EBS) from Future  Electronics

Component of EBS™

NEC LCDs

EBS™ uses NEC’s innovative displays, available in sizes from 5.5"-15.0", which includes their SFT technology displays (ultra wide viewing) as well as their wide operating temperature (-10ºC to 70ºC) displays (custom EBS™ solutions using NEC LCDs can be provided up to 23.0"). NEC TFT LCDs offer fast response times, and extended temperature liquid crystal material.

LUXEON® LEDs

LUXEON® emitters are the highest flux LEDs in the world, delivering the brightest solid-state lighting solutions available. LUXEON® III White LUXEON® LEDs typically produce up to 40 lumens per Watt (based on 3.4V typical, 350mA rated current).

Sipex Driver Chipsets

Each LED solution includes a Sipex SP6137 driven LED power board (see Figure 3). The LUXEON® LEDs are driven by a 12V power input. There is also a PWM input and a 0 - 5V dimming circuit. Typical LED backlights can be driven to sub 1 nit with the PWM circuit.

Based on the SP6137, this compact circuit provides a stable drive current for LUXEON® LEDs. The SP6137 is a synchronous buck regulator configured to provide constant output current for this application.
