TFT LCD controller

I'm looking for a low cost solution to connect a TFT LCD at least 7" to the microcontroller by 
UART/SPI/I2C. I have to show only static graphic with touch operations. FT800 chip looks nice, but 
unfortunately it only supports a resolution up to 512x512, and 7" TFT has 800x480.

Since Intel bought & destroyed Chips & tech there is no such
chip on the market (they had the b69000 and the b69030).
Silicon motion, a Taiwanese firm, have some similar parts
on their website but I think they are hybrids and they
are not available through the major distributor channels
(I have never tried them out).

FTDI -> USB -> cheap android tablet.  I've heard of software bit banged
VGA but really, that's sick.

Nothing sick about bit banging it - if you can. But it is far from
being practical.
The tablet solution is not exactly a "display", boots for ages etc.
Not that I do not do it, only I use VNC (RFB) over the net, at 100MbpS
works great (have used it at up to 1280x1024, 1920 x 1080 should still
work fine).

Have you already chosen a TFT display ?

If not:

Controller is a SSD1963, already soldered down with touch controller.

At the risk of being called the spelling police, i think he meant slick. ;-)
