Assuming the question relates to a normal personal computer, the answer is: technically, they don't interface at all, at least, not directly. The keyboard interfaces to the computer through a physical port. Software (device driver) monitors the KB port for keystrokes. Operating System (OS, e.g., Windows XP) interprets what to do with the keystrokes. OS sends display commands to a graphics driver, which sends hardware commands to the graphics board, which in turn sends signals to the display to display. If the OS is broken for any reason, the path is broken, and keystrokes do not show up on the display.
