Which LCD is this?

I have an LCD here the size of a PDA screen 2" x 3" that I bought from a surplus store. I cannot find any mention of it anywhere online.

There are only two numbers behind it: LRH9J5035A

130D0597

It has three set of connectors. One is just two large pins (backlight?) onto which Ive applied voltage upto 9V both ways with nothing.

The second is 4 pins which seems like touchscreen to me the way the pins spread out to the four general areas of the LCD. The third ribbon, has 18 connectors which go through through-holes enough number of times to throw me off from what is the data bus and which are controls.

Where can I find further information on this thing? Is it complete garbage because noone has the datasheets or even a quick pinout sheet?

The LRH prefix somehow tell me it is an LG part. Any ideas?

Thanks.

Ive tried the various alps sites and checked their lcd datasheets of most similar LCDs to get an idea. Theres no help there. It seems like in the LCD business, they keep things hush so older lcds have NO market at all, fuelling the LCD market further.

I now have a small stack of nice cheap LCDs that I cant find info on. But this one is nice and small, perfect for my applications. I dont want to spend $150 on something like this with a datasheet.

I'm guessing as I have not seen the modules you have, but this link has similar pins as you have described... it's for a LRH9J515XA

which has you LCD and 2 others with various options, then searched more on the LRH9J515XA.

Searching for LRH9J515XA finds some other interesting PDFs, admittedly not in english, but gives you some ideas.
