    Emen - I can't do your homework for you! and I won't, the idea is to help you find it yourself not do the work for you, so you have to take the link I sent you and see what you can find from there, as I said you should call the manufacturer and ask them, they can and will Help you, they want to sell the cards. and as I said, that was just one link of many possible, but they all have differnet items they support and all have different abilities as far as inputs and such, you need to pull up Google like I did and do a simple search for LCD controller, and add the model number, you will be amazed at what you find.

    and when looking at the pages for these cards they tend to show only a small portion of the cards they actually support (another reason to call them!!!) because things change all the time they don't always update the lists for the the cards. and since most screens are made by the Main electronic makers, there are a lot of smaller unknown name screens that are actually the same as the Big name ones, just using a generic or proprietary name. again doing some simple searches can get this info for you. so just because the model number or manufacturer are not listed does not mean for sure it won't work, you will just need to do a little more footwork first.
    (I have found, while looking around that that monitor does take an Analog RGB input, but only with the controller board, not the DSP, but the first board in line which is what you are missing.) this is the same screen that is in the PSone Portable LCD monitors that are sold at best buy, etc... (see what a little research will find!!) so it is possible that if you looked on ebay for one of those PSone LCD monitors that has a broken screen, you could get it and replace the screen and you will have a working screen with a composite input.

    ok, it doesn't matter what the LCD came out of, they are all the same thing basicaly. the orange cable(or Ribbon Cable) is the cable that takes the signal from the DSP(digital Signal Processor) and directs it to the correct location on screen. it does not however have an Analog to Digital Converter on it, so to answer your question NO, you can't just solder on a VGA connector, you still need to convert the signal from analog to digital. almost all of the input methods there are happen to be analog, VGA=Analog Compsite=Analog, RGB=Analog, if you look at some of your home entertainment equipment, the only digital output will be an Digital optical output, this is Fiber Optics, currently the best method for transferring digital data. so in almost all cases you will need to change the signal from analog to digital and then pass the digital signal to the little card(DSP) you have attached to the monitor there.

    try this for a google search:
    "lcd controller samsung 5 inch LTS500Q1"

    - and look at the return, there is a company in the list, http://www.beyondinfinite.com/product/lcd/samsung_lcd_display.html - they make a controller for that LCD and it's listed and everything, they will even customize the inputs and such for you. but again calling them will ensure that you get what you want.

    there are plenty of others out there who make similar items, you need to go and look for them, do lots of searches and try lots or different wordings and see what you find.


    here are a few other places to look:
    EarthLCD.com
    reachtech.com
    radiance display technologies

    and I am finding that because these can be used as displays for kiosks, Signage, Motion Displays and other trade show type stuff, that there are more people making these cards(based on these ideas.), and there will probably be even more next year.

    I know it has been said but you have to learn to solder. It woudlnt be hard. Especially if you have made cables before

    Ok, so like many others, I have read the entire 12 pages posted over the last 4 years. I know the ebay guy that sold the controller that yesyesuk used, is pretty much gone forever. I believe this controller is probably the best choice though. So please, someone post the brand, model, anything to identify it, so I can at least do some searching for it, to see if anyone else sells it. I know you have all posted links, but most of them are dead now, a brand name and model, etc would be very helpful at this point.

    kylboy06 - see the post I wrote just the other day (3 above this one.) it has new links and a few website addresses to check out. there is NO Specific Card Name or Manufacturer for these as of yet. check the links I posted the other day and look at the sites I listed at the bottom of the post and you will get some ideas of how to look for a more specific model, or function.

    I've just checked on my converter. There's no manufacturer or model number on it that I can find (I only see one side of the PCB, don't want to dismantle the whole display again). I think these are boards from a normal TFT monitor, maybe slightly adapted to be used with laptop panels.

    emenblade, could you please edit your post and remove the images or make them smaller? They are not useful to solve your problem but make the page extremely wide and take ages to load...

    BIO - I think you miss understand, the Controller does not come in any of the (Laptop)LCD monitors. they will all need a controller of some sort. like YESYESUK said, they may be Controllers from normal LCD monitors that are converted to work with laptop LCD's.

    the link you gave is for a cable that connects the LCD in the laptop, so it is useless inless you want to make it work in the laptop again. this cable does connect the LCD Panel to the controller for the Laptop though, so if you wanted to know what connector the Controller card would need then this will show you, and NO, it's VGA compatible.(that would be a function of the controller card.)

    Hey folks,

    I have a disfunctional compaq presario 1700 series CM2080 and want to convert it's LCD monitor into a normal screen to run external inputs such as DVD players ,PC's etc.

    hi... i got an old "acer travelmate 4152" lcd display...
    can i convert it so that i can i use it for my desktop...
    as far as i know its difficult to convert vga to lvds.. ok..
    but when i googled about my lcd it says that
    "15 inch xga tft lcd display"
    google returned no sign of any lvds vth this display...
    so.. does it means that the display is "xga" and not "lvds"..???
    if so... is there any chance to convert the display to desktop monitor using the vga output pin....??

    XGA is the native resolution of the panel (1024x786). LVDS is the way the signal gets into the panel. Nothing to do with each other...

    Ok, sorry I have been neglecting this thread lately. All lcd's, laptop, desktop, portable dvd player, have to have some way of converting the signal from whatever input to lvds so the lcd itself can display it. Its a matter of finding the right controller that works for your model of lcd. The controller i found, use, and posted here, and that other users use, is no longer available for sale from the website ( http://kitsparts.com ). i am in the process of finding a controller for an lcd I pulled from a portable dvd player for a carpc project. As soon as I find one i will post the link to it here.

    What exactly are you trying to do? Use a laptop display in an external lcd monitor case and controller? If so, I'm pretty sure it won't work, unless the lcd is the exact same model as that used in the lcd monitor. The controller boards in regular lcd monitors is proprietary to the lcd it was built with. Google around, there might be a way, but I'm pretty sure there isn't.

    Ok so I recently got a broken Dell INSPIRON 1150...I broke it all apart and pulled the monitor. I want to make this a vga desktop monitor, I noticed everyone mentions controllers is there one that will be compatable with the monitor and if anyone needs any additional info, pictures let me know!

    Thank you
    Im brand new to this!

    I am still looking around for another company that sells the controller cards to the average consumer instead of bulk to factories. Find the model number on the back of the lcd from the Dell.

    So... All I have gathered from this thread is that unless you have 80 million hours to devote to hacking driver code and soldering, you need to spend at least 199.00 on a converter card... Okay, I'll just buy a nice 19" Samsung HDTV.
    Has anyone managed to make a less expensive card that only supports DVI? My understanding is that one reason this project is so difficult is because of the mixed type of signals that LCD's and VGA adapters use. (Digital vs. Analog) My question is, instead of converting the LCD's digital display into an anolog display for VGA why not let it remain in digital and use a DVI adapter?

    I apologize if I missed something

    The converter cards are not that expensive. Most of them are about $100 and cheaper. The hard part is actually finding cards that are not being sold as bulk. And the DVI signal still has to be changed into the signal that the lcd can translate into display (LVDS).

    hmmmmm, this appears to be a SatNav display with a resolution of 480 x 234. And according to the (rather sparse) data sheet here:
    http://www.datasheets.org.uk/pdf/3968456.pdf
    is has "TFT specific analog RGB" as the input format. It will be rather tricky to find a converter for that...

    In my opinion not worth the effort, especially seeing the low resolution.
