Frame memory driving method

摘要

A frame memory control method that reads out video data from a frame memory at a reading speed twice as fast as a writing speed, and a sequential driving type display using the same. The method includes: storing (or writing in) video data corresponding to one frame in the frame memory in sequence; reading out the video data of a first group including one of the video data selected from odd numbered video data and even numbered video data stored in the frame memory at or after a half point of a period for storing the video data corresponding to one frame; reading out the video data of a second group including another one of the video data selected from the odd numbered video data and the even numbered video stored in the frame memory after reading out the video data of the first group; and transmitting the video data of the first group and the video data of the second group to a transistor to drive at least two light emitting devices in sequence.
