vgPocket LCD datasheet

If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.

vgPocket LCD datasheet

Post by Corscaria » Wed May 17, 2006 5:57 pm

Great news, I seem to have found the datasheet for the vgPocket Max LCD.
http://www.optrex.co.jp/us/product/cata ... 654aee.pdf

With this, it should be much easier and safer to use this cheaply aquired LCD in portables and other projects.

It only has RGB input from what I can tell. How easy is it to get RGB from composite?

For what we want, not very. definitely doable, but it'd be hard to make it portable size friendly, unless you you use SMT parts. You need a chroma decoder and sync seperator, and a handfull of supporting parts (caps, resistors, clock crystals, etc.) I have a professional made composite to RGB board with regular sized chips, and it's 3"x5".

It looks like the screen also needs a clock fed to it for the signal type being used. That makes it slightly more difficult to use with a RGB console. The good news with that is that the screen can be run in PAL or NTSC mode, with the right circuitry.

Corscaria,
You are truly the man! Everytime I go into Radio Shack I debate buying a few of those to portabilize, as they are on clearance.

This is exactly what I've been looking for.

Good Job!

Anybody read the datasheet fully to see if it's digital or analog rgb input?

Does Vcom (pin 15) stand for composite video?

Probably ground (Vcom ~= Voltage Common)

It's Analog RGB, wrote on page 2. Page 18 has a composite video graph too.

Yes, but I'd recommend that someone that fully understands the datasheet for the screen hack it first, and creates a howto for the rest.

I need to print out a copy of the datasheet myself, and see if I can understand it a bit better. It's a bit hard to read onscreen, especially since some pages are rotated 90 degrees.

It works for me now, acrobat installed an update, and now it works. I don't know if the update did it or what, but it works now.
