White LEDs

[cyborg_0 at iquest.net]

Siemens makes one that has the red, green, and blue leads brought out seperately. Some new 
large screen panel displays are going to use them.. There is even an app for a pic chip to 
control the color hue by PWMing the various leads. So, the next generation panels could be 
exciting indeed!!!
