Navigation Display
The navigation display uses a liquid crystal display (LCD). The LCD is a 7-inch-diagonal, thin film transistor (TFT), stripe type with 336,960 picture elements. The color film and fluorescent light are laid out on the back of the liquid crystal film. The touch sensor on the front of the LCD consists of a touch sensitive resistive membrane with a large number of possible touch locations. The navigation display transmits the signal from each operation key and the touch switches to the navigation unit over the GA-Net bus.
