where to get big LCD displays?

Crosswinds

Hello!

Im searching for some bigger LCD displays, for use with prop´s.

I want them to be like 40x4 or something like that, and i want them to have serial interfacing, like the smaller ones, that parallax sells!


But i really cant find any,someone knows where?

LCD that big you will have a hard time finding. I can build you and LED display that big but it will not be cheap.

For about the same price as displays that size you can get "DVD headrest displays" which are meant to be mounted in the headrest of your car so that the kiddos can watch Shrek for the 4,096th time as you drive down the road; you can get 7" diagonal displays from Amazon.com for around USD$70, they take NTSC input, and nicely display 40 characters by 13 lines with the TVTEXT object. Due to economies of scale TV sets are always going to be cheaper than data displays, and for some weird reason the LCD industry refuses to standardize driver inputs so if you don't want to write a new driver every time the hardware changes, you can either take an expensive standardization used by a few industry people or a cheap standardization used by the entire world. NTSC doesn't use the display optimally, but it gives you a nice easily read display cheaper than typical smaller QVGA solutions.
