Re: Re: LED Backlight

Oops, looks like this message has been in my drafts for months..

OK, and apparently there are some Newhaven LCDs that work on the
Wavestation and should work just as well on the K5 :
http://www.mouser.com/Newhaven-Display/Optoelectronics/Displays/LCD-Displays/LCD-Graphic-Display-Modules-Accessories/_/N-6j73aZscv7?P=1z0wujzZ1yzunjcZ1z0wrx9Z1z0wtd6Z1z0wu0sZ1z0wsz8Z1z0zl2b&Keyword=240x64&FS=True

Same pinout, and uses the "RA6963" controller, equivalent to the T6963 used
on the K5's Toshiba LCD.

There is Blue/White, Green/Black or White/Black available. The White/Black
uses a "better" LCD type, which gets you better viewing angles.
