5.6" TFT Joytech - any experiences?

Hi there!

I just saw this 5.6 inch TFT Colour Monitor from "Joytech". It is originally designed to be used with PS2. Look right here:

http://www.joytech.net/product.asp?id=115

Very low price too, costs only 100 US$.

Does anyone have any experience with this type of display? Is it easy to dismantle? Is it possible to attach a VGA source? What are the exact specs?

Thanx.

if you would have really searched instead of just clicking the "i've searched box" you would have read that these panels are no good at all. they have very low resolution and low contrast. it'll give you a bad image if you blow it up to any size.

if you go to partsexpress.com you can get the same panel for cheaper that $100.00 and if you get it from ebay you'll get it even cheaper.

thanks for your lovely answer. there is no entry for the joytech lcd in the whole forum though. i did search.

maybe there is someone who can tell me some more about this monitor, the only things i know is that it has AV inputs and no regular vga input.

The bottom line is that you cannot buy a 5" range vga resolution lcd module for $100. Unless you want to strip and older lcd projector, your **** out of luck.

Because i had some unexpected payments to do I delayed the start of my "big" pj project but because my friends told me i could never build a pj myself I wanted to show they were wrong.
So i used parts i had lying around and some other cheap stuff to build a "pre-big-pj-project" as a test. I now have a nice little pj with an ok quality to watch tv. Its a portable thing which i'm kinda proud of. I know its not nearly good enough to show the dvd quality off to friends, but it's nice. The lcd is an old playstation screen which is low resolution but not too low. You'll never believe what lamp i used ... a 50 watts halogen spot used in ordinary bedroom lighting I noticed that a 500watt worklight delivers about the same lightpower as the 50watt: the difference is that the 500 watt light spreads the light all around: the whole room is brightly lit whilst the 50 watt light focuses its light with the help of a small built-in lense. the angle of the beam is about 30°.
OK, my image is very dark but is IS nicely watchable when you limit the projection size to about 1,5meter diameter.

Stop bashing people who want to try to build a DIY-mini-PJ: its nice to watch tv, but if you want to watch movies on a quality-image with friends or family, dont bother cuz you'll need a better project. I'm gonna build mine as soon as i know what lamp to use (250 watts or 400 watts MH -> check the new topic!)

I'm considering building a portable Mini Projector. I have my OHP setup, wich I love, but I want something small to take to other people's houses, use in my room, etc. It would be very cheap to do, wich is one reason I am considering it. I figure I would use a 4" or 5" PSOne LCD, a Projection TV Lens, and possibly a Lights of America flourescent worklight(if not, some type of cheap halogen). I can probably put all this together for less than $150, maybe even less than $100. I think I'm going to try the VGA hack on my PSOne LCD tomorrow, if that works I think I'' definetly do it.

 

[Sir_Vival]

Wont that look like total crap though? I mean..ouch, those LCDS have a mega-low resolution.

 

[drwenkman]

Ehuwiko:

what's the technical data of your ps1 lcd? do you know if it's the same as the ps2 lcds?

thanx. wenkman

Hi wenkman,
vergiss die LCDs. Die PS1 undPS2 LCDs machen dir pixel wie zeigelsteine auf deiner leinwand. Schau das du ein LCD Panel bekommst davon hat du mehr.

Gruss
Bernhard

Hi wenkman,
forget these small LCDs. Die PS1 and PS2 LCDs will produce pixels like briks on your screen. Look for a decent good lcd panel, that would be better.

I've heard the VGA hack is pretty decent looking, but I don't really know how it works. There's a website that shows a picture of a 5" screen, and the text is readable at size 9! Like I said, this is for a small projector, like 50"-60", and a major factor in the design is protability. I really want to use a VGA or SVGA 6.4"-10.4" LCD eventually, and build it into a computer case. Unfortunately, those are pretty hard to come by.

 

[verbose mustafa]

Trust me on this one, using a tv projection lens and a loa will not make it portable. The thing will weight a ton and be much bigger than you relize.

 

[drwenkman]

thanx for your replies.

but is there anybody who can tell me the actual facts of those ps2 (joytech) 5.6" tft displays?

 

[Ehuwiko]

Only the company can tell you the specs. Contrast ratio and response time cannot be measured without high-tech lab equipment. The most you might be able to find is the resolution, wich'll probably be higher than 320*240, but not much.

but is there anybody who can tell me the actual facts of those ps2 (joytech) 5.6" tft displays?

Trident mobile lcd TV has a Toshiba 5.6" screen and it' s specs;

5.6” 4:3 TFT LCD screen (res. 960x234, brightness 185 cd/m2)

I thought it has same specs, because of the dimensions.

 

[drwenkman]

Thanks for your answer. I also got some specs from the vendor:


1. resolution of the tft display - 960 x 240

2. response time (rise and fall) - NOT KNOWN

3. contrast ratio - NOT KNOWN

4. number of colours - 262,144colour

5. vga input possibility - YES

does'nt sound too bad. but for bigger screens the resolution might be too low.

 

[mhelin]

Real resolution for that TFT is 960/3 x 240 = 320 x 240. For some reason they have announced the number of horizontal subpixels (R,G,B), not the number of pixels (multicolor) as we know them from TFT monitors.
