Bob Davis has written an article on interfacing a 2.8 inch SPI TFT LCD ILI9341 with the Arduino Uno:
Over the weekend I figured out how to interface a 2.8 inch SPI TFT that has a ILI9341 chip to an Arduino Uno. All it takes is eight 1K resistors. Most people use a 4050 IC. Here is the schematic
I am using the Adafruit ILI9341 driver found at github
Note that the Adafruit LCD has level shifters for 5 volts built into it.
