Freescale Semiconductor has introduced the MC34845 LED driver with high-speed pulse width modulation (PWM) capability. This six-channel device is designed to allow LED backlights to operate at ...

This is a reference design for an LED display-backlight driver. The design uses a boost power supply with adaptive feedback for efficiency and linear current sinks for a high dimming ratio (2000:1).

This is a reference design for a SEPIC/linear LED-display backlight driver for eight parallel strings of 8 WLEDs (white LEDs) at 70mA/string. The dimming ratio is 4000:1. The input voltage is 16V to ...

SAN JOSE, Calif.--(BUSINESS WIRE)--Power management and video/audio interface leader, Kinetic Technologies, is expanding its display power solutions portfolio with the introduction of KTZ8868. This ...

White LEDs (WLED) are increasingly becoming the light source of choice for backlighting applications due to their attractiveness in power efficiency and form factor. Display solutions in portable ...

While all of my own devices and monitors don't have PWM dimming for their backlighting, there are some monitors at work which do appear to use PWM. Now many of these monitors are years old, and I ...

CCFL backlights are the most common backlight technology and are used in displays ranging from 5.7 to 23 in. or more diagonal. They can have from one to 24 or more lamps mounted along the edge of the ...

Light-emitting diodes have become the lighting source of choice for almost all illumination applications. Incandescents, fluorescents, CFLs, and other types are fading away in favor of the almighty ...
