The application of LEDs to the backlighting of large LCD panels poses unique power management considerations. The inherent configuration of the LEDs behind the panel, known as direct, or around the ...

The BD93941EFV, developed by ROHM, is a white LED driver designed for large LCD panels. The device is a DCDC converter type that employ an array of LEDs as the source of light. The BD93941EFV has ...

A typical LCD consists of liquid crystal material with transparent electrodes and polarizing filters. Applying voltage across the liquid crystal layer allows light to pass through in varying amounts.

Abstract: Higher luminance efficacy, faster response, lower power consumption, longer operation life, wider color gamut and environmental issues makes RGB LED backlight driving system suitable for ...

Sunnyvale, Calif. — Maxim Integrated Products has introduced a high-efficiency driver for white light-emitting diodes (WLEDs). The MAX8790 targets large LCDs that use an array of LEDs as a light ...

Abstract: This paper proposes a light emitting diode (LED) backlight power system for liquid crystal display (LCD) panels. The proposed power system is regulated by ...

No one likes a recession, with the possible exception of Hollywood. And why is that? The answer is simple, if not obvious, box office receipts go up in an economic downturn. Another form of ...

Several bias voltages are needed for supplying and operating an LCD panel. In most cases, specialised integrated circuits with several charge-pumps are used to generate the different voltages. As the ...
