hmm these LCD panels are becoming scarce..

(I'm korean and not so good at english- please understand my grammar mistakes)

You guys seem to want to know about the LCD panels which are used in the DIY projectors at the korean site(http://diypro.net).

The exact name of the panel is "SAMSUNG LT104V3-131", and it's 10.4 inch and supports up to 800x600 res.

131 is pretty good (and also I'm using this one) for the projector because of its cheap price(one moth ago, it was sold at 50000 ~ 60000 won ; 1200 won is one dollar, roughly) and high quality.

But now, it's becoming over 80000 won but it's so hard to get one even though in Korea.

So instead of that, users are using Samsung 100 panel(10.4 inch but supports 640x480; cheaper than 131: approx. 4~ 50000 won) or 8.4 inch panel(but these are pretty expensive).

Hm. anything you want to know more about Korean projectors? so leave a question here- I'll answer as much as I can

aha, hoontang was before me ^^

I couldn't notice him- 🙂 So let's co-work. ^^

Anyway- mario questioned about keystone problem..

Hmm I think that's not so much a problem in here(http://diypro.net)because these problems are easily removed by moving fresnel lens, lcd panels correctly. And other guys in diypro.net also says so.

I had this problem also, but I removed these keystoning effects by simply moving fresnels and lcd. Now I have a 100 inch square screen with clear pixels.

Those links aren't the results of one projector design. It's a DIY forum like this one... only a little better 🙂 (In terms of design I mean).

All of the designs I saw use everything people in this forum are trying except... all of them are homemade cases, they have smaller LCDs and use IR filters to keep the heat down. Plus I saw a number of DIY triplet lenses in their designs with zoom and resize features.

Other designs use OHP parts but none of them keep the actual OHP case. Which is why I recommend building your own case no matter what. You cant just slap a different bulb in your OHP, add some fans and think you found a solution.

where is the basic?

interesting to see these guys use a 10" lcd screen and lenses smaller than 70mm (2.8") and at the same time solving about everything that cculd go wrong: keystoning, coloring etc...

i think some of them use smaller thatn 10.4" panels but have had no one here that tells me anout them.

J-P

uvodee: took the words right out of my mouth... I can't believe that some of these aren't using LCDs < 10"...

One thing I really want in an LCD is resolution though... so I guess I'm stuck on the massive projector until they come out with LCDs that are <= 15" and >= 1024 x 768... prefferably up to 1600 x 1200 would be terrific. I would love the super high resolutions because you could set the resolution to extremely high, say 2400 x 1800 and still have half inch size 8 font on the screen... wow.. a programmers dream... you could fit so much stuff on a 2400 x 1800 resolution desktop... *sigh*

LCD Sizes

They are using smaller LCD......

°ø±¸7ÀÎÄ¡ lcd -----------(ÀÌÂù´Ô)>>>>>>>>>>7 inch LCD

I have also seen a 8.4 inch screen on their site.

Also seen where they have a 150 watt bulb producing 4200 color

br /> ÞÅ»·¥Ç?150w 4300k -----(³²»ó¿ë´Ô)>>>>>>>>wow Ididnt know you could get that much color from 150 watt

I cant read Korean but I can see some of the numbers in their text post

it's a different rating system..

Most resolutions given on the small lcds are using a different rating system. They are usually rated in 'dots'. If you want the real resolution divide the horizontal by 3.

Sad but true.

However if your primary use for your projector is a television (broadcast) you would be quite happy with say, a 1200x400 (dot) 7" lcd, so long as you didn't want a huge screen.
