Techniques for 92% Efficient LCD Illumination - AN55 Linear
TechnologyThis publication details several LCD backlight circuits which
feature 92% efficiency. Other benefits include low voltage operation,
synchronizing capability, higher output power for color displays, and
extended dimming range. Extensive coverage of practical issues includes
layout problems, multi-lamp displays..... |

Transistor Considerations for LCD Backlighting: High Efficiency DC-to-AC
Conversion - Zetec Semiconductors Applications Notes A
study of the parametric requirements of Bipolar transistors for the
self-oscillating resonant "Royer" inverter with respect to LCD
backlighting,... (app note added 2/06) |

Ultra Low Power LCD Indicator - This circuit serves as an ultra-low power
replacement for multiple LED on-off indicators. It also has the advantage of being
easy to read in full daylight. With the parts shown, it is possible to display four
bits of information…. [G. Forrest Cook] |

Ultracompact LCD Backlight Inverters - AN81 Linear Technology It has become
desirable to fashion laptop computers with large area screens, leaving little room for
the display's backlight inverter electronics. Miniaturization limitations of high
voltage magnetic transformers impose limits on achievable space reduction. Another
voltage step-up technology, piezoelectric transformers,..... |

White LED driver backlights LCD and keypad - 13-Nov-03 Issue of EDN
Designers widely use white LEDs to backlight color LCDs and keypads in handheld
devices, such as cell phones, MP3 players, GPS navigators, and PDAs. Their spectrum
and brightness represent near-ideal light sources. One possible configuration for a
phone or a phone/PDA combination is to have a group of three LEDs to light the display
and six LEDs for the keypad..... [Design Idea by Fabien Franc, Catalyst Semiconductor,
Sunnyvale, CA] |
