Connecting a watch LCD display

Hey Guys,

Im trying to connect a watch kinda display from an projection clock to my arduino. I have absolutly no clue watsoever how to do it. It's a 4 digit display. Do you guys have any hints for me? I attached a pic of it.

Thanks in advance

Mike

Have a look at the component driving it and do a data sheet search on the web.

Well i tried, but it's a cheap asian bord with a chip and a blob epoxy on it, and no numbers that could identify the lcd.

They are almost always custom displays driven by asics. To keep costs down it's the same asic that operates the timekeeping, buttons, LCD, and everything else. There is no discrete LCD driver. And certainly there is no datasheet.
