Abstract Gallium Nitride (GaN) light emitting diodes (LEDs) are viewed as the next
generation of display technology as a replacement for both liquid crystal displays (LCDs) …

Background/Objectives: LED short and current imbalance problems generate the over
currents in the LED strings and they damage the LED back light system. To solve these …

This paper describes an implementation of a wide-range dimming controller of a LED
backlight for Avionics applications such as a control display unit (CDU) and multi-function …

As the appearance of local dimming technique, the current existing test methods are not
suitable for testing the power consumption of the LCD TVs using the local dimming …

In this paper, the perception of flicker in time‐sequential or field‐sequential 3‐D LC TVs
driven by LED backlights is described. The seriousness of the perceived flicker and its …

If some LEDs are shorted, overcurrent flows through an LED string consisting of multiple
LEDs connected in series. In the LED driving circuit, a current regulator with semiconductor …

In recent years, with the enormous improvements achieved in light-emitting diode (LED)
technology in terms of lifetime, luminous efficacy, power rating, and color property, LEDs …
