Can I turn my lcd laptop monitor into a desktop monitor?

the cards seen here http://blog.360.yahoo.com/blog/slideshow.html?p=8&id=1MjY.AsidqfrUUFzkb0HaN3v2LIR seemed to work as explained on page 7 or 8 of this thread, but the seller stopped and has been unreachable. find one of these cards and you are set.

 

I was checking out his auctions too. Let us know how that purchase works out. I'm just itchin' to grab one but seeing other prices out there this looks too good to be true.

 

Howdy - it seems to me after reading the whole thread that I need one of the boards yesyesuk was able to get. Does anyone know where to find something similar or if the seller will be making more?
Thanks!
P.S. - I just found this thread and you all should be congratulated. This is good stuff.

 

Well, it turns out the adapter didn't support my LP133X7 (C2CC) I believe what i saw on teh guide on the auction was actually (Q2CC) instead of (C2CC) so if anybody has a pin conversion chart or would liek to buy my adapter, as it supports many other panels, I may be selling it in the near future.

 

Hey, i found this thread whilst looking for the same information about converting a laptop screen for desktop use.

I understand the screens take a digital signal etc, but i have a question.

My screen is from a packard bell easyone silver, the screen is good and i have 2 inverters and 3 motherboards to play with.

Looking at circuit diagrams for the board, it seems i have a small chip (U2 LVDS DS90C363MTD) which takes R,G,B, vsync and hsync signals, and converts them over to the lcd connector, does this mean it is taking an analouge signal and taking it over to digital?

Looking at the diagrams there seems to be 6 red, 6 green, and 6 blue input pins, so i dont know if just wiring these up to a vga R G B signal will work.

Please look at the following disgrams:
pic 1
This shows the basic connections to the screen, note RGB VSYNC and HSYNC, just like a vga connector.. not sure about the other pins.

pic 2 (big!)
the right middle shows the same chip, the left is the SiS graphics chipset.

Could this be converted to vga? and why are there 6 red green and blue pins?

Any help is much appreciated!

 

This should help pretty much everyone... 7 hours of google searching... lol good luck all

 

in regards to the dell remote capabilities.
i'm not sure why you're so impressed, this remote capability has been available for years. however this has nothing to do with attaching a laptop LCD to a desktop system.

 

OK, I finally got the correct cables for the logic board I bought for my lcd. I found the company that sells these. The website is www.kitsparts.com , the logic boards are cheap and they work.

 

thanks brad for finding this website. this is exactly the converter I received from the ebay auction mentioned earlier in this thread and is works great ever since:

ty yesyesuk that is what I will do.. although i think im going to buy the $72 package. But Do u know where the backlight inverter is on thhe monitor we have?

 

Hello,

I've been following this thread with great interest from the beginning and it has sparked my project when I was luckily given a laptop panel.

I was given a Samsung LTN141X7-L06 panel, it came froma Toshiba 1600 laptop.

I hoping to make a VGA LCD panel and I've taken the steps of yesyesuk to fufil my project goal.

I bought a LCD Interface card kit from ebay. It's the same as the one found on www.kitsparts.com (I bought this one http://www.kitsparts.com/shop/index.php?main_page=product_info&cPath=17_38&products_id=608)
. It's very well made and looking at it I think it will work with my panel. The I gave the seller my panel number so to find the right cables and etc.

I would like some further advice on how to assemble this together. I would to know if I have all the neccessary parts, and whether my initial setup is okay for trial.

The picture below is of the new inverter attached to the LCD panel. Is this circuit correct? I mean, I couldn't check if the negative and positive wires of the panel match that of the inverter. I had to solder them because the connectors didn't quite fit.



I would also like to know is do I need to plug in the VGA cord to my computer for this to work. Can I simply plug in the inverter and test if this works. I wanted to ask ,because I' m afraid of any short circuits or damaging any components.

Any positive input is greatly apprecaited.
Thanks

I am still waiting on mine. I was asked what model the screen was and how many pins i had on the "Panel Side" and well i just told him the model # and well, he said he will se wat he can do. (this was kitsparts) If he sent it out around then, I should be recieving it sooon. I am hoping. but does anyone know where I would find the number of pins on that specific model? its the one yessyesuk used and made. same laptop and everything.

 

Redpanda7 : you will need an input of some kind to see something on the screen, but if you power it up witout an input you should at least see the screen light up a little bit showing it is waiting for input. I am unsure if they have a blue screen function built in or not.

Fright01 : just because the laptop is the same model does not make the screen the same as I have found in the sony's I tear apart all the time. sometimes I tear up 3 or 4 to find 3 different brands of LCP panels inside, some are listed in the table on the website for the cards, but some are not( this may only be because they are newer and the table is not updated very often. ). sorry but I am not sure where the pins are on yours, but you should be able to see it as it will be a connector with about 30 or 40 pins (some are flat and some are ribbon cable connectors)

 

kreyon, Thank you for your swift reply it is very much appreciated. Do you happen to know if the wiring as seen in the image of my previous post is correct? I'm not sure if the LCD is designed to be a passive device that can withstand accidental short circuit.

fright01, the guy at kitsparts is very nice indeed, you can send him a few pictures of your panel along with the connectors and he might be able to better help you.

On a side note. I had paricular difficulty finding a suitable LCD interface card for my panel because as I later found out that my panel was part of a later batch and therefore was given an unusual model number, it is in fact the same as the best selling version...it's just not printed on the outside.

 

Actually, Kreyon, The Model he said is the same one i have. Also, its the same laptop. but thanks for telling me which connector to look at. I would send him pictures but he never asked for anything past when i told him the model number. So i think he has it pretty well figured out. but ya, thanks for telling me wehre to look. Would I tell him how many wires or how many slots there are in that connection? btw its not the one with 30-40 i think it would be the flat orange/brown one, that looks like a laptop keyboard cable, but w/ a metal connection at the end. How could I count that? it is rather difficult to see?

 

Hi redpanda7. I think you're on the right track here.
When I build my panel with the converter I first connected the lamp the wrong way (somehow I assumed it would be AC, not DC). The backlight on the display just wouldn't come on. It took me a while to figure out but eventually I just swapped the cables to the lamp and it worked. What I'm trying to say is that you don't need to worry if you got the cables the wrong way round. It doesn't seem to do any damage. If the light doesn't come on, just solder the cables the other way round. Unfortunately it's not easy for me to check which way the cables need to go onto the inverter board as I would have to dismantle my panel. When you try it out make sure you cover the bare wires where you soldered the extension wires on. There's some rather high voltage and you wouldn't want to get electrocuted or short circuit them!!

As for testing without connecting it to the PC, the least you need to do is to connect the converter board to the inverter and the panel and the power supply. Otherwise the inverter board will not get switched on. If the converter board is the same I have (very likely) then it has an on-screen display for all the settings, just like a "normal" TFT monitor. So when you switch it on without connecting to the PC you should at least get something in the panel. Maybe that's only for a short while as the converter board disables video when it doesn't detect a signal from the PC (standby mode).

Hope that helps a little... Let us know how you get on with it. And make sure you post some pics of your working panel ... ;-))

The replies are very much appreciated.

I've gone ahead with my project now and I've seem to have come to a slight problem.

When all the parts and connectors were finally connected up it seemed the panel was dead. No backlight, nothing. I tried several times with adjusting the VGA input signal, reversing the power connectors from the inverter and testing the various circuits with an amp meter. I think my donated panel is defective.

So with that discovery I've now bought a 2nd hand screen from ebay, with the rough spec as my old screen.

This will hopefully be more productive.

I'll update once it's fully working.
Thanks again

 

oh ya that is too bad, well i can just wish u luck how long did it take for u to get your converter from kitsparts? (anyone who got from there)

 

it took about 14 working days for my package to arrive. That's not too bad considering that's a journey from Hong Kong to London.

 

ha great got it today i am still figuring out how to put it on but thats why i came here i am going to read over and then hopefully have a tv for my bedroom
