Aircraft
During approach the flying First Officer noted that he had just seen all PFDs and CDUs blank off then immediately back on. No EICAS or status messages appeared. The rest of the approach was uneventful until touchdown when the autothrottles disengaged automatically. A report was submitted and we asked Maintenance to meet the aircraft so we could further brief them.
All cockpit displays went blank momentarily twice between downwind and final. Upon landing the autothrottles disconnected by themselves. (I always fly with them on; got no warning).
During descent a B777 First Officer's PFD; ND; and CDU momentarily blanked twice then returned to normal. After landing; the autothrottles did an uncommanded disconnect.
