    LCD Hacking queston

    I have a digital camera, a Sony Cybershot DSC-P100, which died in a fire. So, I decided to take it apart, and the LCD screen looks like it might still be usable. I did some googling for the serial number, but all I can find are sites that sell replacements.

    Can anyone suggest where I might find a data sheet, or some other way of figuring out the proper voltages and signals needed to operate the thing?

    There are multiple numbers on the thing, but I think the part number is ACX329AK-1. googling for this returns many results related to LCD screens, related to purchasing.
    It has the number AM329AKA etched on it. Searches for this bring up similar results, and one russian site that seems datasheet-related, but the site doesn't have the datasheet.
    It's not stupid, it's advanced.

    Your first clue should be the battery voltage if you just feel like diving it. If I remember DC to DC converters are expensive from a design perspective to use. If the battery is not available the AC adapter is another good source of information. Is its output ac or dc? What is the output voltage and current rating?

    Hope that gets you started.

    Just because you can doesn't mean you should. This applies to making babies, hacking, and youtube videos.

      The battery's available, I could look up what the voltage is. What I wouldn't know, though, is what the control scheme is for actually displaying anything. From my searching, I think there might be a pre-built driver available for it. I'll have to investigate further.

        YTF, it's rare when you can get TECH support here. Consider yourself in the fringe!

          You are on the correct track. What you will want to remove from the camera is the LCD, lighting unit, and the display driver while still attached to each other. You want the specifications for the display driver (which will likely be the chip in-line between the camera and the display). Keep in mind that it is possible that the camera manufacturer integrates the LCD display driver with the primary processor so you may end up looking at how to program the SoC that drives the camera.

          The protocols to drive these units are fairly simple and you can probably get a good idea of what they will require by looking at similar displays in their class. If you can't find information from simple Googling, you may wish to contact the manufacturer directly and request the data sheets. It wouldn't hurt to strongly imply that you were looking to buy a lot of them for your Big Commercial Product.

          They are not that pricey and they are generally integrated into the driver circuit these days. The voltage problem isn't with the display so much as the lighting. Even using LED lighting, most LCD manufacturers put the LEDs in series so that each LED maintains the same current and the brightness will be more even across the whole of the display.

            I think the backlight is integrated in the same case as everything else. The LCD was connected to a very dense, stacked circuit, by those flat circuit plug thingies. The circuit looks hard enough to trace, and it's stacked, and inside a metal case, and it's covered with gunk from the fire. o_O.

            I'll get pictures of it up, later today. But, the best idea for getting data on it might be to just call Sony directly?

              I think I'll come here for my next plumbing problem.

                Well if you need help on that, I can help you on the disposal side of the plumbing, just not the supply side. ;)
                A third party security audit is the IT equivalent of a colonoscopy. It's long, intrusive, very uncomfortable, and when it's done, you'll have seen things you really didn't want to see, and you'll never forget that you've had one.
