Off Topic, because the only good way to do it that i know works with LCD, but just to let you know:

Some Manufactorers manage to create LCD Displays in a way that it looks like LED Displays in normal conditions ( black background with illuminated pixels of the data to diplay ) and like a cheap LCD in sunny conditoins -> inverse ( light background, dark to black pixels ).

So with this technology there is only 1 ( One ) certain amount of lighting that makes the display unreadable, everyting above and below renders a perfect readable display.
Now THAT's good ...

( my behatred Clarion 2175 + DSP did so, a crappy piece of **** besides that, it costed more than an empeg, Arghhh )
