Adafruit 7.0" 40-pin TFT Display - 800x480 with Touchscreen (2354)

This 7.0" TFT screen has lots of pixels, 800x480 to be exact, an LED backlight and a resistive touchscreen overlay. Its great for when you need a lot of space for graphics or a user interface. These screens are commonly seen in consumer electronics, such as miniature TV's, GPS's, handheld games car displays, etc. A 40-pin connector has 8 red, 8 green, and 8 blue parallel pins, for 24 bit color capability.

This version has a 4-wire resistive touchscreen attached.  It's exactly the same TFT display as PID 2353 but with a resistive touch panel.

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. The backlight requires a 125-150mA constant-current mode boost converter that can go as high as 9V instead of small displays that can run the backlight off of 5V.

For that reason, it is a companion to the Adafruit RA8875 driver board, which is a chip that can handle the huge video RAM and timing requirements, all in the background. That's the best way to interface this display to just about any microcontroller(including Arduino & friends) If you want to control it from an HDMI or DVI output, check out the TFP401 driver board.
