Narrative:

I exceeded 250 kts below 10;000 feet on departure. This was the third leg of a 3-leg duty period. This flight was my first flight on the line in an lds (large display system) aircraft. For our departure clearance; we were assigned runway heading to 4;000 feet. I was the pilot flying. On departure; heading select and VNAV were selected. After VNAV was selected; the autopilot was engaged. I called for flap 1; flaps up. Going through about 2;500 feet; I noted that the aircraft got an altitude capture. As we approached the 4;000 feet level off altitude; ATC gave us a clearance to climb to 10;000 feet. We reconfirmed with ATC that the cleared altitude was 10;000 feet. After dealing with this distraction; my attention came back to the lds primary flight display. At this point; I realized that the aircraft was accelerating above 250 kts at 4;000 feet. I had no time to analyze why the aircraft was accelerating. I just had to react. By the time I reacted; I saw the aircraft accelerating towards 300 kts. I bugged the speed back below 250 kts. I knew that I had to also comply with the new altitude clearance; so I selected flch initially and set 250 kts. In the speed window; quickly correcting back to 250 kts; and climbing to 10;000 feet. ATC said nothing about our airspeed deviation. I did not exceed any flap or aircraft speed limits. I think the major contributor to this incident was this being my first flight in an lds aircraft. My instrument scan was not as fast as on the classic displays and I let a few external distractions that normally wouldn't be a problem; keep me from flying the aircraft.

Title: B757-200 flight crew reported unfamiliarity with new cockpit display; resulting in the aircraft exceeding 250 kts below 10;000 feet.

Narrative: I exceeded 250 kts below 10;000 feet on departure. This was the third leg of a 3-leg duty period. This flight was my first flight on the line in an LDS (Large Display System) aircraft. For our departure clearance; we were assigned runway heading to 4;000 feet. I was the Pilot Flying. On departure; HDG Select and VNAV were selected. After VNAV was selected; the autopilot was engaged. I called for Flap 1; Flaps Up. Going through about 2;500 feet; I noted that the aircraft got an altitude capture. As we approached the 4;000 feet level off altitude; ATC gave us a clearance to climb to 10;000 feet. We reconfirmed with ATC that the cleared altitude was 10;000 feet. After dealing with this distraction; my attention came back to the LDS Primary Flight Display. At this point; I realized that the aircraft was accelerating above 250 kts at 4;000 feet. I had no time to analyze why the aircraft was accelerating. I just had to react. By the time I reacted; I saw the aircraft accelerating towards 300 kts. I bugged the speed back below 250 kts. I knew that I had to also comply with the new altitude clearance; so I selected FLCH initially and set 250 kts. in the speed window; quickly correcting back to 250 kts; and climbing to 10;000 feet. ATC said nothing about our airspeed deviation. I did not exceed any flap or aircraft speed limits. I think the major contributor to this incident was this being my first flight in an LDS aircraft.
