‘Ccfl’
A Electronicstalk guide
Start with the news release
LCD modules come with long-life LED backlights from
Trident, which we summarised at the time by saying "Range includes nine new LCD products, available in four screen sizes ranging from 5.7 to 10.4in, with QVGA, VGA, SVGA and XGA resolutions.".
Several months prior to that,
we featured the news release Backlit LCDs come with full industrial specs from
Sharp Microelectronics Europe: "Displays combine the high resilience required for industrial applications with the benefits of an LED backlight.".
In July 2008, we covered the news from Arun Components
- take a look at Inverters are made for driving backlights
which says: "Range can power up to six CCFL tubes, and devices are available with and without dimming controls.".
Take a look also at the news release from Hitachi Europe - Display Products Group, Widescreen LCD modules to the fore,
as well as TFTs target handhelds and signage from GPEG International,
and Power supplies ease LED backlight design from Endicott Research Group.
