Just out of curiosity...
If we ignore power supply and backlight for the moment, do you think it would
be feasible to connect an LVDS (technically FPD-Link I guess) LCD panel to
the GTA04, without a lot of extra hardware?
There is a beagleboard project how to interface
the OMAP processor:

using this chip:

If so, that could be a neat mod for those of us with broken laptops lying
around... Though it would be more pad than big phone I guess.

Don't we need a larger form factor? Like a 4.5 screen? Has there been
any discussion along these lines?
For a GTA04++ there is no need to change the video system.
It is capable of driving75 MHz pixel clock and HDTV resolution.
And, a larger display area does not necessarily increase the
pixel density. They just become bigger (unless we want to
increase the resolution as well).
What may need to be changed is the power supply and it may
need level shifters. But this is the simplest part in solving the equation.
If we get documentation.
- finding a new screen
This is also quite tough. Either, they are not available through
distribution.
Or if they are, a VGA display with touch and 3,5 - 4,5 inch usually costs
~ 100 USD (e.g. Avnet Express, Mouser, ...).
I think we all want to have a display with superior-resolution (like iPad)
but cheap as water. And available from steady production. And with decent
documentation. The last one rules out choosing replacement iPhone 4S
displays...
