Narrative:

At approximately 2;500 ft on approach; both first officer main flight instruments failed (pfd and nd). There was a short delay; and then the pfd switched to the nd CRT. The outboard CRT [pfd] remained blank; and a strong electrical burning odor was detected. Oxygen masks were donned; and a decision to declare an emergency was made; and the approach was continued to an uneventful landing. Rescue trucks were waiting (not requested); and followed us to the gate. There was no time to advise the flight attendants; as we were less than 2-3 minutes from landing; and in the process of configuring for landing. We did not have time to run any smoke/fumes checklists; as the decision to land as soon as possible was made.
