Any idea where I can get an "inverted LCD" like the one used in this product?
Thanks.
I think you can do that with any old graphic LCD by just "drawing" with an "off" bitmask on a background that's all "on" bits.

If you use a KS0108 or equivalent graphical LCD, the GLCD library in the playground has the capability to write normal or inverted graphics or text and the mode can be switched at any time.
Thanks.
I was asking about that particular display, used in the Sander Mulder's Pong clock. I don't think he used some custom designed LCD for his (limited edition) product.
The product description lists "inverted lcd" as one of the components (see http://www.sandermulder.com/pdf/pong_clock.pdf)
A google search for "inverted lcd" returns results related to DLP projectors.
It looks like he is using a white (or light gray) pixels on a dark background. You can get graphical LCDs that display light gray on a dark backgrund from some of the Arduino suppliers (http://www.nkcelectronics.com/graphic-lcd-module-112864.html) but they are smaller than the one in Mulders clock. The LCD in your link looks like its 80mm high (if the clock is 120mm high).
Back in my youth there were electronic wrist watches with a polarizing front panel. Flipping it over made the clock black and the digits white. Nice effect.
Modern screens still need a polarizing film, but I doubt one can flip it over.
This one, from Sure Electronics, seems to be of the same dimensions:
The difference is in background colour, dark blue instead of black.
Not cheap either.
