HOLA ,
i'm from portugal
i'm very impressed with this project, it seems to have good quality of image for the lcd that you used. so i have a few questions about the lcd.
you used a sony psone lcd or any other brand?
your lcd are moded to vga? or it's the normal lcd? this lcd's can be pluged to vcr's and dvd? i read that only modding to vga you get good quality so i was thinking if it's true because yours looks awsome.
Give me a bit info about this lcd and how you input image to it, please.
Thanks for your time.

I use a 5" Sony screen for PSONE, it does not have special adjustments and I connect video with a cable of original use for video with RCA exits. It generates very good image as I show in my photographies.

Now I recommend to use a 7" LCD tv. It has more pixels. Please look it in the following direction:

http://www.lumenlab.com/forums/index.php?showtopic=3109

ok thanks for your reply

i guess i'll first try with a 5" lcd from a psone.. it's cheaper than a 7" and if i like the result then i'll upgrade with a better ecran.. i guess it's the best for me as it's my first projector.
i'd like to ask you a few things about your psone lcd..
the first one is hwo do you plug your lcd to eletricity? how it works? it works as standalone from a psone?i never saw any so i imagine that it gets power from the psone.. i am wrong?
the second question is are u sure that your lcd is has 640x480? i read on other forum that it only has 320x240 unless you make the mod to vga then it will have 640x480. do you know something about this?
Let me know please because i'm very interested and i'll probably start builing a projector with a 5" psone lcd.
Thanks for your time

Hi, Of your first question, the PSone Sony LCD connects to the electricity using the eliminator of the PSone.

Of your second question, the Sony LCD It´s resolution is 320 x 240, I was bad s, I translated erroneously a text. But even the low resolution, it generates very good images. Especially considering the low price.

Regards

er.. what is a eliminator? i'll need something from a psone? it's a charger?

Ok, is not an eliminator, is a tranformer, since there changes the voltage of entry that in México is of 127 volts, to 16 volts that needs the Panel Sony for PSone. You can buy it where you buy the PSone. In the following image I show the transformer.

Im trying to decide what type of diy projector to make, 7 in or 5 in. But I had a few questions i was hoping someone could answer. First off, how well does the image look in real life. Does it look as good as say a standard tv or is there blockiness and screen door effects. Secondly, how big of a difference in quality is there between the 7in and 5in lcd. And Lastly, Im newbie at diy projectors and was wondering how easy it would be to make a 7 or 5 inch projector.

Thanks
Q.

The image of the projector that uses a 5" LCD is good, using a 7" LCD is very good and using a 15" LCD its excellent.

Its equal of difficultly to build a projector of 5 " or of 7 ", since it is not easy to obtain the parts. It is easier to construct a projector with panel of 15 " since Lumenlab sells you everything necessary.

Is the 5 inch as good as say your standard tv. Or is there major quality difference?

the Sony LCD's resolution is 320 x 240, but can you use the vga mode to get the 640x480? And if so how do you do it?

Thanks
Q.

The difference between the cinema and the TV is that in the cinema you center 100% in the movie, since the darkness allows you not to distract you with your environment. The TV is small, the cinema is big. The TV is not good to see movies, the cinema is very good to see movies. A projector that uses a 5" panel is OK as cinema its image is brilliant, but its resolution is not very big but its sufficient. The resolution of a projector that uses a 15" LCD panel is excellent. The money in your pocket and the availability of parts to construct it will help you to select the one that more is convenient for you. Its not possible change the LCD Psone resolution.

gra_pelayo,

thursday i'll receive my psone lcd.
i don't know how to open it, can you give me some help.
my questions is.. theres any part of it that i can remove? i mean any cable that will not be necessary or something.
and how the light goes thought the lcd? i have to remove something that ussually gives light to the lcd, right?
can you explain me how to do that, so i can be sure i wont damage the lcd?
Thanks in advance.

I bought a PS1 5" screen and realize now that I need a cable for it:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...ssPageName=WDVW

I tried cables from Radio Shack, but nothing worked. I'm waiting for mine to arrive, will test it and report back here (if you want to wait before you buy one).

-LumenSF

well i allready ordered my psone lcd, i guess i have one cable like the one you just bought but i can't tell for sure at the moment.
You will also build a pj with the lcd? if so let me know so maybe we can help each other.. specially because i'm a bit afraid to open it

yes i was looking at this and he did pretty good.

im going to try and make my design smaller though

light source--ir-heat glass--frenel--lcd--crt lens

it will be something like that

wish me luck

Jees thats a ps1 lcd!!! this is making me re-think my plans....

I am going make photographies disarming a PSone LCD screen, stepwise and with indications of since make it, treating it in order that it is not damaged. I will try to publish them in Lumenlab at the longest next Thursday. If I can I do it before. Regards

yea i got one today i tryed to open it but at the bit where the speakers are something is stopping it i dont wanna put a screwdriver in and damager wires needed the wire im using for my screen is an audio one but in the end its a wire and works perfect

thanks a lot

I just disected a sony psone lcd today. I didn't feel like being overly cautious, so when I discovered that there was something holding it closed at the speakers, I carefully applied a generous amount of force. Underneath the speaker cover (you know the little metal piece with all the holes) there are two screws. If someone wanted to disect the screen without applying a generous amount of force, they would only have to take the little speaker covers off. After the screws are off, the speakers are attached to the main circuit board by wires with connectors that can come off. Hopefully that helps.

the metal mesh to protect the speaker from being bbburst

Hi was was wondering if anyone knows anything about the ps2 game screen. it is 5.6 inches and i would like to use this for my projector kit. would i need diferent lenses the the pro kit or will they work. any ideas anyone?
thanx

that cable worked with you?
i have my ps one lcd now and i tested with a cable like that from my canon camcorder and the image was moving from top to the bottom looping and black and white.. anyone knows whats wrong?

ok forget
i don't know why but my dvd in standby without any dvd inside gives that weird scroll and black and white. but soon as i put a dvd inside playing everything works fine.
The same happend with a vcr.
Nice image for the size of the lcd.
Soon as i found a detailled tutorial on how to open the lcd i'll do it and start building my projector.
if anyone has detailed photos on how to do that would be very apreciated.
Thanks

go to that site and he has how to dismanttle it

I think that is a test signal, similer to the signal given by a VCR with no cassette. I think its to enable easier channel identification.

hello
i have a few questions about how to dismantle this lcd.
theres any cables that i can disconect ?
i have numbered because i guess this is the only ones that seems to be able to be pluged and unplugged.
Please help me out.
Thank you

I stripped mine a few days ago.
1- this is the cable to the backlight. I disconnected mine and it still works fine.
2- this is to the lcd, don't touch DO NOT DISCONNECT
3- these are to the inputs i.e. power,av,headphone one of mine was glued in I would not disconnect them. Don't Disconnect
4- each of the speakers has a little cable with a connector. These are fine to disconnect and they pull right out.

after i remove the backlight what will happends when i turn on the lcd? i wont see nothing at all while i don't put a projector or something behind it?
how can i deattach the lcd flrom the backlight? how does the backlight looks? :S
sorry about my dumb questions.. can you post pictures of the light and the lcd alone?
thanks

Here you go:



You will not see anything on the lcd after the backlight is removed. In order to see anything you will have to have it plugged into a video source, and have the power plugged in. Once those two things are plugged in, you can hold the lcd up to a light source to see if the lcd works. I held mine up to a window and saw the picture with sunlight going through it. (It would not be a good idea to stare at the sun!)

The first picture is of the backlight. The connector you see unplugs from the connector in the second picture. Then the backlight is held to the lcd screen by a metal frame with little clips. Carefully pry up the little clips and then the backlight will pull out. That is all that you have to do.

After you pull the backlight out, you have the lcd and the little metal frame. The metal frame is near perfect for mounting the lcd to whatever. What I did was I put some silicone II around the outside of the lcd and that holds it in place really well. Now when I end up using the lcd I will just have to build a holder for the frame boards and screw the little metal frame into the holder.

The second picture shows you the other side of the connector and a little bit of the lcd. The white stuff around the lcd is Silicone II. It seems to work really well.

I can tell you exactly what I did with the Silicone II if you want me to.

hi
thanks for this pictures
yes i would be very interested in udnerstand how you used the silicon II because i didn't understand that part very well..
by the way.. how did you open the plastic where we have the power the av and that stuf.. i unscrewed the 3 screws but even after that i was no able to open it.. it seems theres something glued...
other questions.. when we open the lcd.. theres 3 + 3 screws should i remove them? in yoru other post you talk about glue in that area.. i don't understand where it is...

a bit off topic of this "how to dismantle a psone lcd".. you did the vga mod? if so can you give me a few info about that and also pictures? i saw in one site that it can be done without sold wires to the control board, only solding wires between 2 cables.. one vga and one playstations AV cable.. you have anything about this mod?
the "reds" in your lcd are mor evisible than the other colours? theres any way to control it?

Thanks for your help. keep posting pictures if possible.

hey thats a pretty good idea with the silicone.

i did it different though. i took apart the backlight stuff and then was left with thte plastic frame. i cut the edges of the plactic and put it back in with the lcd and metel frame.

all the silicone is for is to hold the lcd to the metel frame. because it doesnt hold by itself.

i really want to do the vga mod but i dont know how. it looks kinda hard to me. but if you find out how to mod a multi av cord tell me how you did it. anyways if you do find one where will you plug it to.

Hi everyone ...

The cable I metioned in my last post arrived and it works! Save yourself the frustration at Radio Shack and buy one of these on Ebay. Slam dunk.

Question: does anyone know if one can extend the ribbon cable from the LCD to the controller card? I need to extend so I can position my LCD in the middle of my Lumenlab fresnel lenses. Otherwise, I dont have enough reach to make it.

If you're not sure what I'm asking, let me know. I can provide pictures, etc.

-lumensf

people usually dont extend the ribbon cable. what they do is position the board and lcd 90 degrees.

I understand that 90 degrees is the norm :-\

I'm using Lumenlab fresnels which are deeper than the 90 degrees position
allows for centering in the middle of the fresnel

Anyone have any ideas on who to extend the ribbon cable?

Thanks in advance,
lumensf

I think you're going to have to cut the fresnals down to size in order to get it centered correctly. Though in theory, if you positioned the lcd further away from the second lens, this could solve the problem as you could have the controller board lower and not interfere with the picture(if that makes sense, can post a pic if not). As soon as my lens set arrives this is the approach I'm going to take before butchering my fresnals as I want it upgradeable to 15" when funds allow.

Also, if you disconnect 2 in the above diagram, you can reposition the LCD on the other side of the circuit board which gives you an extra centimeter or so to play with.

hears a cite i found with the vega mod explained hope this helps
