3" and handle 480p HD? Sounds like a sweet spot. Cost and controller issues come to mind, though.

480p is SD, not HD. Nonetheless, it would be hella fun to play with but as you hinted, no manufacturer is going to build a VGA or DVI (let along HDMI or component) controller for a 3" LCD.

Actually, 480p is an HD resolution, just not what most people think of as one. The key is that it will let you display a cable HD channel in a wide aspect ratio. SD is 480i.

Regardless, I would build a 3" straight shot 800x480 DIY pj that looked like a box of spaghetti. heh Would run great off of my FT-9964 Ebox.

That's an OLED screen. I thought that OLEDs are self illuminating. If that's so, I don't think you would be able to send light through it, because the Organic L.E.D.s are printed onto a plastic sheet or film, like ink on paper. Unlike an LCD which is a clear glass panel.

Can anyone shed light on that?

Technically 480p is ED not HD. Enhanced Definition is what it stands for.

I think you're right. I can't say for certain that OLED is completely opaque, but I do know that they create their own light and therefor don't need a backlight. This would suggest that the manufacturers wouldn't design them to be transparent.

480p, whether it's HD or SD probably isn't worth using to make a DIY projector IMO (unless you build it a purely a hobby). I bet the display costs... at-least $400 or so.

I guess I am just used to a 1024x768 panel that can only do widescreen at 480p anyway really.

That's an OLED display, you can't shine light through it because it uses light to make the image. It's complicated but it's going to be the new "thing" in the next 10 years probably.

Technically 480p is ED not HD.
And, if you have ED, you know you don't want a time loop.
See your doctor if your time loop lasts more than 4 hours.

Apparently Bob has a new boost of confidence.

Must be caused by a time loop.
