Agreed. I only use LCD's in my laptops. I dislike the image
they present to me -- even when viewing in ideal conditions.
Friends drop off broken LCD's and I repair them and pass them
on to local charities, etc. (apparently, many resell them for
$30-100 -- depending on size).

Projection screens have always had problems with light output.
Rear projections usually suffered from viewing angle, as well.
Ages ago, Kloss (?) made nice front projection systems.
But, in order to get large (e.g., 10 ft diagonal) images,
you still had to rely on dim ambient lighting and/or
"glass bead" projection screens.

I've thought of using a screen based solution and letting the
screen serve double duty as a window shade! (cuts down on ambient
light at the same time).

I think OLEDs will suffer from the same sorts of problems that
LCD's do -- burned out pixels. :-( Thankfully, the only
practical way to do this with a CRT is for the deflection amps
to fail :-(

Pioneer (?) makes a modular projection system like this.
You cascade the boxes and tell them what sort of arrangement
(3x3, 4x4, etc.) you have and each box sorts out which portion
of the signal it needs to display.
Unfortunately, since they are physical boxes, there are (very
small!) borders on the edge of each. So, it isn't completely
seemless (though they worked hard to make the borders VERY
small and unobtrusive)
