Define "Displays". Are you referring to the actual LCD Display on the laptop or the internal Graphics/Video Adapter? Notebooks rarely have need for a LCD Display driver since the OS provides that in most cases. If you need a driver for the Graphics/Video Adapter, you're in the wrong forum.
If you need a driver for the Graphics/Video Adapter, you need to also describe it.
Or just visit the Sony website(s) to check for driver availability:

If you're downgrading from Vista to Windows XP:

Go to the following link, type your model number into the "Auto Detect" box, then click GO.... this will then show you the drivers available for your laptop.
