Hi,

Liquid Cristal Display... I guess you mean these old (still big market though) of banners filled with leds and the text scrolls line by line, thanks to different lightning of the leds... only these led-boxes aren't quit LCD...

If you mean this, I've seen one once... only the problem is where?...

I'll let you know if I found it back.

Zif.

Hi,
Just wrote something like this for a LCD fonteditor at work.
If you specify exactly what you want, I might adapt my component
to your needs. No promises.

Zif, LED is "Light Emitting Diode". LCD is "Liquid Crystal Display".
Didn't you know that? ;-)
If the fore- and back-colors can be set, there should be no problem however.

hi john, sure I knew it :-)... but I know only scrolling LED-boxes (mostly seen) and no scrolling LCD displays... (what so special on a LCD scroller? Especially programmed on a screen?) Zif.

Hi again,
1. Color. Most non-TFT displays use dark gray-black segments on gray-graygreen background (not including filters or backlighting) while most LED's emit red, green, yellow, infrared, blue or orange light.
2. Segment response times. LED's usually switch on/off in about 10ns while LCD segments switch on/off in about 10ms-1000ms depending on temperature.
;-)

A LCD-scroller will have blurring (see Kjofol vqf-player, for instance).
Blurring costs CPU-time, and CPU-time is something to be stingy about on multitasking systems. So...
