Unused LCD Display Screen


You are bidding on an unused LCD display made by Plotech in Taiwan. Dimensions of the viewing area are 4" wide by 3.1" high. It appears to be a 320 x 240 dot matrix with a green/yellow backiight. The diagonal measurement is 5". Mounting holes are 5" apart horizontally and 4.3" vertically.
There are 3 Sanyo LC79430 and 4 Sanyo LC79401 ICs on the back. The connector is a 14 contact dual row .1" standard ribbon cable connector.
The part number appears to be 20-20075 -3. I have been unable to find any data on it. I believe it is a fairly standard interface, but have no way to test it. The manufacturer doesn't seem to want to give out any info. You can see the chipset data sheet --HERE--
Someone finally figured out how to run this display. He says:
Here are the instructions on getting them to work using LCDStudio on a pc which is what I did. One is in RTF Format (so all can read it) and 24meg so I zipped it, the other is in Word 2003. I've made them quite detailed with screen shots so it shouldn't be difficult to follow! I also got them working on an atmega chip, but theres certainly enough info in the docs for someone to link them to their arduino etc using the graphics chip provided too.
So you can see his instructions in a zipped file --HERE--
Or as a Word file --HERE-- . The last photo shows what he got it to do.
Email hlandis at hotmail.com with your questions, although I don't know any more than is in the instructions.
New unused, in original factory packaging, only opened to take photos.
Sold with a 10 day no DOA warranty.

I have the specs for the chipsets, but from what I read it will not hook up to a parallel port, it will work with VGA but you would have to find the right frequency. I am in the process of finding it out. Here are some links:
