Abstract
The present teaching relates to method, system, medium, and implementations for refreshing an LED display. A signal signaling a timing for refreshing the LED display is received. In response to the signal, a bit-based image block is retrieved from one of a pair of alternate buffers pointed to by a read buffer pointer, which is then toggled to point at the other of the pair of alternate buffers. The bits in the bit-based image block are sequenced in accordance with a connection pattern in which lights of the LED display are connected to generate sequenced image bits for the bit-based image block and control signals are generated for refreshing the lights of the LED display based on the sequenced image bits. The alights of the LED display re the refreshed based on the control signals.
