Apparatus and method for refreshing process in displaying images unto led panels

Machine readable and non-transitory medium having information recorded thereon for refreshing an LED display, wherein the information, once read by the machine, causes the machine to perform:

• receiving a signal signaling a timing for refreshing the LED display;
• and
• in response to the signal,
• retrieving a bit-based image block from one of a pair of alternate buffers pointed to by a read buffer pointer,
• toggling the read buffer pointer to point at the other of the pair of alternate buffers,
• sequencing bits in the bit-based image block 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,
• generating control signals for refreshing the lights of the LED display based on the sequenced image bits, and
• refreshing the lights of the LED display based on the control signals.

A system for refreshing an LED display, comprising:

• an image bits sequencer configured for
• receiving a signal signaling a timing for refreshing the LED display,
• in response to the signal,
• retrieving a bit-based image block from one of a pair of alternate buffers pointed to by a read buffer pointer,
• toggling the read buffer pointer to point at the other of the pair of alternate buffers, and
• sequencing bits in the bit-based image block 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
• an LED refresh unit configured for
• generating control signals for refreshing the lights of the LED display based on the sequenced image bits, and
• refreshing the lights of the LED display based on the control signals.
