I am curious to see what kind of lighting they use for the LCD. I have a Casio QV-770 camera, really old, 640x480 max resolution, 4MB storage, no card slots, serial port used for download via a 1/8 audio style jack. They use a custom fluorescent tube , it is white and square the size of the LCD and about 3mm thick with a small glass pipe on the side for the electrode wires, never seen anything like it.
I plan to post photos of the tear down when I get time.
wow the casio is 15 years old, must have been one of the first.
