Adafruit Industries Adafruit Industries 7" 40-pin 800x480 TFT Touchscreen Display
This is a "raw pixel-dot-clock" display and does not have an SPI/parallel type controller or any kind of RAM. The display is supposed to be constantly refreshed, at 60Hz, with a pixel clock, V sync, H sync, etc. There are some high end processors such as that used in the BeagleBone that can natively support such RGB TTL displays. However, it is extremely rare for a small microcontroller to support it, as you need dedicated hardware or a very fast processor such as an FPGA. Not only that, but the backlight requires a 125-150mA constant-current mode boost converter that can go as high as 9V instead of our other small displays that can run the backlight off of 5V.
