I got to take home a cool LCD today that they were going to throw out

Does anyone know how/if this can be used as a PC LCD?

[mtekk]

Can you get us the numbers/names of some of the bigger chips (What I mean by bigger is the ones with at least 18 pins). It probably has a microcontroller in there, we need to know what it is. I doubt you'll be able to directly interface with the LCD, but the microcontroller can act as a bridge (probably will end up plugging it into a serial, USB, or parallel port). Nice find btw, that looks like a gold mine for electronics parts, and by the looks of things it hardly a year old.

[Eclecticos]

Cool! The first thing I would do is write down the make, and model and attempt to find a online pdf manual. Seeing that it comes with a memory card i'd probably be allot easier to erase it and add new content. I wonder what is on the memory card and what format it is?

[TheGreatSatan]

It played a short movie about setting up a wireless network.

The only thing I could find of relevance Here (http://forums.bit-tech.net/showthread.php?t=115461), and Here (http://www.harbaum.org/till/lcd2usb/index.shtml) <=-

I know for a fact i've read a forum where people were taking screens out of everything,
phones, cameras, portable tv's, ect, and reusing them for different applications,
but I can't seem to find it. They were discussing transistor film.

The only thing I can find now are LCD manufactures forums.

Found it! Here (http://www.skippari.net/lcd/) <=-
You may need one of these controllers?

If you can determine what type of connector you input has, other than the obvious memory slot I may be able to find something that will work. Then all you'd need is a powersupply with a DC current equal to that of the batterys.

If i had to guess I'd say your input is on the third picture up "white connector" under the power cable wires.

Here's more detailed pics of the connections and stickers

Never heard of AU

Could you get a close up picture of the other side of both boards. Also, have you tried removing the sticker from the 20 pin DIP chip on the tan board. It's looking more and like the tan one is only for power, though that data cable is misleading. That DIP may be the key to figuring out what that board is doing. Also, tracing the leads from the ribbon connector (the one that actually connects to the LCD) to any chips on the board, mapping this out is important to figure out what is going on here. You may have some luck looking around http://forum.lcdinfo.com/index.php

[Eclecticos]

AU is likely "AU Optronics (http://auo.com/auoDEV/?ls=en)"

I found allot of places that sell LCD controller Boards but I don't see AU on the displays list.
| Saelig (http://www.saelig.com) | Aurora (http://www.aurora.se/controllers.htm) | EarthLCD (http://www.earthlcd.com) |

I think your best bet is contacting AU Optronics for a manual.

Woot! I found it. :banana: Here (http://www.digitalview.com/controllers/csg.php) <=-

It must have a controller board in it for the original device to have been functional ... and my guess, given the original app, would be that those D batteries are rechargeable. I'd also guess the compact flash has an OS on it and the presence of the S-video out, and the descriptions of functionality on the box, also imply this may have been a fully functioning computer of some kind rather than just a screen.

Update:

One of the chips on one of those boards is the 8DIGIT 8D02E, that board is the LCD controller:
TFT-LCD CONTROLLER
MAY 2006, Version E
1. General Description
The 8D02E is a timing controller for small analog TFT-LCD panel. It provides horizontal and
vertical control timing to TFT-LCD source and gate drivers. The controller has built-in phase
lock loop system, which can synchronize the master clock with the horizontal and vertical sync.
signals from a classical TV system.
2. Features
Support 16 kinds of 16:9 display mode.
Support 8 kinds of horizontal display resolution mode, from 240 to 2880.
Support 2 kinds of vertical display resolution mode, from 234 to 468.
Master clock frequency: 28.9 MHz max.
Including master clock frequencies divide by 2 function, and half function.
Acceptable the external & internal master clock input.

Here's the spec document (http://66.102.9.104/search?q=cache:aOzu8XXpYJoJ:fckuo.myweb.hinet.net/spec-pdf/8D02E.pdf+8D02E+LCD&hl=en&ct=clnk&cd=1)


Given the unit's wide functionality it must have other interesting boards in there too. Looking at the box, the Compact Flash also has three other video tuts on it and also must have an OS to control the systems functionality, for example the box says you can broadcast to the web using the unit and view your cameras from anywhere.

Here are my conclusions: This is the LCD controller board, just needs to be identified and you can get the datasheet and get going. Probably it is the only of these boards you need to get the thing working with a PC:

In this pic the top board is a mini computer, complete with Compact Flash for the software and the lower board is the associated input/output board for the system. You can see what (I guess) are the four numbered camera connectors on the front edge and the LCD output on the back right. That LCD cable fed into the controller board before you pulled it to bits if I'm guessing right.

update: I'm concluding this was a point of sale display device programmed to inform buyers about Panasonic security systems and was not a product on sale. Is that right?

[TheGreatSatan]

Yep, it was just an informative display, not a "for sale" item. Now to find a way to get a PC's display to run through that 9 pin connector.

I contacted AU for info on the monitor

Good eyesight I was having trouble determining what was what, and turning my head to the side. :)

What I was attempting to find was an LCD controller board for that lcd display with a "Regular" input, adapter, or an add on card, with USB or similar.

If AU responds with a manual or schematic of some sort you can probably use a VGA or Serial Data cable as you input similar to what was done for the "PSOne LCD (http://www.bit-tech.net/modding/2004/07/07/psone_lcd/2)"

Try and identify the controller board. It may or may not have come with the monitor. Take pics, back and front, peel off stickers and look for part numbers etc. I suspect it's the controller board documentation that will tell you what the nine input pins are and how to use them.

[Vertigo]

Helluva find there.

First thing I thought when I saw this was adding a screen with a looped video on that memory card, like a resident evil mod with the red queen saying you're going to die, etc. You could set up several and change them on the fly, or get even weirder with it. LOTS of possibilities with this bugger.
