I need help finding out about UMS-744FD-1B. I need to find the manufacturer and the spec sheets for it. Any help will be great.

Thanks

The number does not google, so please see if you can post some clear, high resolution pics of the front and back.

Also, do you know if it is graphic or character? Do you know the resolution?

I can identify manufacturer of this LCD.

Greetings a few years later,

I have just butchered an old Xerox inkjet printer, and my LCD module has part number UMSH-3061ANV-W. This one has 10 connections: contrast, +5V, 2 grounds and 6 data pins so presumably it is parallel 4-bit data. Each of the 6 data pins is buffered through one gate of a 74HCT04 hex inverter so they are all inputs only.

I am trying to find docs on it so I can use it, and so far I have dug up the following:

- The manufacturer is U.R.T. - that's United Radiant Technology Corp in Taiwan.
- The info on how to use this is not exactly falling into my lap. The manufacturer's web site lists what controller chip(s) they used in a bunch of similar displays, but no other help yet.
- here's the manufacturer's web page with info on what the part numbers mean. Based on the similarity of part numbers, yours appears to be a graphic module, while mine is a 20 x 2 array of 5 x 8 dot matrix characters.

You will see that they used a bunch of different controller chips (20!). I have made an alphabetical list:

A lot of those part numbers are "HD44780 Compatible". I would bet that a standard HD44780 library would work, if you can figure out the data pins.
