fun with 1" LCD? or no...

hey all
i've got a busted fujifilm finepix A201 digital camera in my hands... any chance i can do anything with the 1" LCD? or is that way too complicated...
thanks a lot for info


btw, just fyi... the camera was busted by giving it a bit too much voltage with an AC - DC adapter... heh.. don't ask.
i just took it completely apart and couldn't find any burned traces or anything that looked unusual...
something that i found odd is that the + and - of both the ACDC adapter input and for the batteries both suggest that there's a complete circuit (with ohm meter).... but when you switch it on, nothing happens..

thanks

WEll 1" is way small...but...how about making a custom electronic rheobus with it? That'd be cool.

How would somebody even go about doing something like that...I've always wondered how people get temps and cpu speed to display on those LCDs...

Im not sure, i may try some internet searches on this see if anything comes up..:)

Well on regular matrix LCD's, they connect via serial or parralel or USB, and there are special apps that feed info to them. For the small color ones, im tno sure. They are supposed to act a second screen. I knwo the five inch ones connect via S-Video cables, and act a fulyl functional second screen. Im nto sure how the small digicam screens connect.

I actually hooked up a 16x2 LCD in one of my EE labs today, it's not hard at all. And if you know a little Visual Basic you can easily write a program to do whatever you want. If you want real help, like actual info of whether that certain LCD might be useful, you should post over at www.hardforums.com

tHIS HOWEVER IS NOT A MATRIX lcd. This is a full-color preview screen off a digicam, and it SHOULD act as a minotor. How its hooked up however is a different story.

I got a color ~.75" LCD viewfinder off a camcorder that had the same problem of volatge overdose, again, don't ask. I got the accompanying PCB that connects to the camera over a small 3-pin connector, the trouble is that I can't find any information on how to hook it up.

I think the digicam LCD and the camcorder viewfinder probably have a lot in common. Our problem is that we don't have any idea what kind of video signal it expects and we don't know where to feed it into the driver board.

ok, I was saying he should go to the [H] to find out how to hook it up, maybe he needs a easily available converter.

yeah, i'll try posting there tomorrow or so...

thanks for the suggestion

The screen you have is completely different then a matrix type LCD display. It will have some type of seperate or integrated controller chip. You'll have to locate that chip in order to get any idea how to interface to it. It most liklely is not an analog NTSC or VGA connector.

Possibly WebEE or EETimes could help as well..

I'm guessing you used a STAMP or similar microcontroller. Its easy to do on those because you can output ASCII characters to any position on the display. For a STAMP for example, all you need is to use one of the port pins and everything is taken care of you, all you have to do is use the SEROUT (assuming its a STAMP) command, but the problem is that all these LCDs can do is display text.

If you need color graphics, you'll need to learn the display memory map or whatever it uses and in the abscence of a controller that interfaces to standard video, it could be a daunting task.

If you look into the inards of the camera and find any familair video processors, you might be able to dig up a data sheet and go from there.

you need the custom LCD controller for that screen.. and after that you will need basic EE/programming knowledge to make it even do anything

hmm... ok
thanks for all the replies... guess i won't be doing anything with that then ;)

I guess you could try something like this:

yeah, but a color LCD is MUCH more complicated... which is why i asked..
