Read This Before Posting Anything About LCDs
« on: December 03, 2003, 11:16:59 PM »

A word about LCDs: over the years, many people have asked questions about using bare (no controller) LCDs pulled from broken monitors, laptops, photocopiers, and the like.  This is a quick guide to help you ask the right questions.

Laptop LCDs/LCDs from broken monitors:
In short, forum response has gone from this:
Quote from: winterstick
you won't like this....

laptop LCD's need a controler card to work properly, there are a few places that sell them, but they are expensive(read ~$200).

to this:
Quote from: merlinicorpus
...must control... ...banning... ...fists of... ...rage...

That's right, merlinicorpus will straight up ban the next person who asks about laptop LCDs.  No one on this board has ever taken Winterstick's advice and purchased a controller from EarthLCD.  That means that any advice we would give you (besides sarcastic and angry invectives) would be from google, which is something you can do on your own.  However, if you do spring for the controller and you need help wiring it up, it would be fair game.  For starters, there's a good thread at Bit-Tech.

Character displays (1X16, 2X20, etc...):
These are a whole different deal.  HD44780, HD44780 compatable, and serial LCD modules are in wide use in the modding scene and many people can give tips and advice on how to get them to work.  There is a great guide to hooking them up right on GT, which can be found here.  Please keep questions specific.

Other displays (photocopiers, Game Boys, etc...):
So you've got a nice graphic display that you've pulled out of a car reciever and you want to hook it up to your computer?  I hate to say it, but you are going to have a hell of a time getting it to work.  Most pulled LCDs are from equipment with proprietary controllers, so the challenge won't be hooking them up, it will be finding the software to run it.  If you're fairly certain somebody's hooked one up in the past and uploaded software for it (a Game Boy screen, for example), then feel free to ask, although moderate preliminary googling would be greatly appreciated.  If it's something you got out of a cordless telephone from 1994, forget it.

Special case: T6963c and SED1330 LCDs:
If you have a graphic LCD with a T6963c or a SED1330 controller and it's smaller than 240x128 pixels, you're in luck.  PowerLCD can get you running.

Just to add to this, LCD Hype, while being difficult to program, does give a good result and supports one long list of LCDs. Just download it and the driver (needed by all LCD proggies) and run, on the dropdown list see if yours is listed!  8)
