okay i want to make a dvi monitor and this is all the info i can think of. if any one thinks i could do this i will bother with pictures ect.


Hey Guys, i have read through this forum and i am very impressed with all that has been accomplished, from the beginning of no its not worth it to oh yeah just click here push that and badda boom badda bing. My problem is a little different, you see because i got my display from a portable dvd player. basically what i have is the physical screen connected to another chip via a long orange sheet? much like the ones in calculators. And that chip has a cable with 13pins that separates. into one cable with 11 and one with 2 for video, and back light respectively, i am assuming. the reason i have not gone to the web site you have accredited is because all that my lcd has on it is serials no actual company name. Now after reading everything i believe i have the lcsd or lcvd chip thing that it was said that i need, but i obviously do not have the corresponding dvi to w/e chip i need.

personally i was hoping that i could avoid that all together some how seeing as i am under age and unemployed, but know and have the tools to solder something.

i do not expect high resolution or anything from this screen seeing as it is meant for dvds which i am assuming run at 640x480 like regular televisions.

Thank you for reading this

ps kreyon, did you ever get anything working for your self, im just wondering cause when you post, it is easy to understand what you are getting at, as if you are sitting in the reader's shoes.

edit i found this much out.
Manufacturer Samsung
Part Number LTS500Q1
Screen Size 5.00
Panel Type TFT
Resolution 320X240

Is it worth any effort at all?

editII the random chip is a back light inverter well it looks incredibly similar to the one at kitsparts, except mine has the orange cable coming from it.

emenblade - Thanks for the nice words, indeed I have built a few of these using 13" and 14" monitors, but it was for friends,one embedded in a dash board, for a DVD player, and two in a mini van in the back of the seats for the kids, but these were done so I could make money, so sadly I have not taken any pics as of yet.

lately I have been looking into other avenues for us to get the converter cards as they are hard to come by once again. and I have a couple of projects slated for as soon as I can find the correct cards for my 17" screen and also I am trying to get a hold of a 17" to 19" touch screen and controller for it. I plan on putting the touch screen in the dash of My Ram 1500, and the 2 17"'s in the back of the seats for the kids.

now as for your little 5" monitor, it would be a great outside panel for a laptop, you put it on the outside of the case and set it up to run widgets that check email and possibly a messanger application among other stuff and it would run all the time and show you information as it comes in( in other words you would see when email arrives or when friends are online, without opening the laptop.)

or if you wanted to you could embed it into a headrest or sunvisor, or even in the dash for a cool extra monitor in the dash(if you have a video signal to feed it.)

if you have a motorcycle you could mount it on it for a video screen, or mount it in the steering wheel and hook it to a reverse camera.

if you have ever seen cars with video screens all over it then you can get an idea of how it could come in handy, it may not have all the lines of resolution for a TV signal or whatever but it will show video and with the correct converter it should look good!

ok yes I know you are under age and un employed but you asked for ideas. heck if you have a bike and a ipod video, you could mount it on the handle bars and play the ipod video through it.

if you are a musician and play guitar, you could embed it into the guitar and play video throught it while you play (ok I like that Idea and may have to do this to my guitar soon!!!!! LOL) how cool would that be!?!?!? (i have a couple old Toshiba libretto's I don't care about any more. they have like 6" or 7" screens) ok I hearby Copywrite this idea, and call patent pending!!! oh here's an add-on idea, mount the monitor up on the neck of the guitar and show chords through it to teach people how to play, they would not have to look far to see the chords and it could be a great teaching tool! I call this one too!!! *LOL*

I guess bottom line is how creative you can be with whats around you!
I know it will be tough but you will have to spend a few bucks to make it work.
having soldering skills will help but you will also need to know how to read schematics and circuit board maps.
you need to know the general components and how they interact with each other.
and the Most Important thing, Have a Clear Picture(in your head) of what you want in the end before you start, and spend a few days gathering the information and making sure you have all required tools and parts, this way you can complete the project without major delays and it will come out better, nothing is more frustrating or stops more projects in their tracks than finding out you will need something (part or tool) that is going to be back-ordered or too expensive, or whatever.

ok, enough for now!!! :)

Hope this was helpful.

well now kreyon, you do have some impressive ideas. me i just would like to mount it in my desk or beside my regular(old crt) monitor. I could be considered a gamer and when im listening to music while in game id love to not have to alt tab out. also my video card (ati sapphire hd3659) has a dedicated video feed thing. My brother explains that i could play a movie and it wouldn't impact my game's performance. Id live to have south park or something running while im doing soemthing else, especially seeing how my computer would do it np.

Any way what i could do with it isn't the least of my worries. im personally not worried about the back light, im thinking of using some leds instead of the halogen bulbs any way. Better economically, and i have them lying around. My only concern is how do i get my lcd to connect via dvi-d rca, vga, scvideo, hdmi(lol), It doesnt really matter which one i have adapters and such.

Also i have a simply understanding of schematics, i have hooked up a ranged car starter before. also my dad is a mechanic, so in terms of tools hes got plenty, multimeters included , not just the cliche' wrench ect. But im still not sure on what i need. i read on here that i need a dvi interface card but i didn't hear anything about that after ward. I can get cables and stuff ( my bro is a computer technician).

Thnx -emen

emen - take a look at this http://www.spectrah.com/product/lcd_controller_board_arv_1700/arv_1700.htm
or check here http://www.spectrah.com/product/index.php ( the main products page, they have a few for different things, even touch screen.)

it is the kind of thing you will need to make your project. there are different models for different functions so call them before ordering and make sure you are getting the right thing. this is only one place to get the cards, there are others, but they are hard to find.

thnx, but none of those controller boards supported on their list, a samsung 5 inch LTS500Q1. And i was eyeing that board, and the board i have in front of me has that little white thing for the orange to plugg into. It came with the lcd. keep in mind that it is from a dvd player and not a computer. any possibility of soldering a vga cable on lol.?

oki and here are some pictures, i warn you they are big. IF they look blurry stand back 10 feet
the pink and white, is for the backlight.
the orange is for the actual lcd
the white going to the lcd is a ground i am assuming
and thing on the bottom is the input, and the power.

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/lc...cd_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
