Abstract
The present teaching relates to method, system, medium, and implementations for LED display. A first signal is received that signals a timing for a next data transfer. In response to the first signal, a bit-based image block stored in a memory is transferred, via a bus connected thereto, to one of a pair of alternate buffers pointed to by a write buffer pointer, which is subsequently toggled to point to another of the pair of alternate buffers. A second signal is received that signals a timing for refreshing the LED display. In response to the second signal, the bit-based image block is retrieved from the one of the pair of alternate buffers pointed to by a read buffer pointer, which is then toggled to point to the other of the pair of alternate buffers. The lights of the LED display are then refreshed in accordance with control signals generated based on the bit-based image block.
