What is 1/4 scan configuration for a 32×16 RGB LED matrix ?

In a 1/4 scan configuration for a 32×16 RGB LED matrix, each row is divided into four segments. Only one of these segments is active at a time, resulting in a sequential scanning pattern. This means that at any given moment, only one-fourth of the matrix’s rows are illuminated, and this process rapidly cycles through all four segments to display the complete image. It helps reduce the number of required output pins, making the control of the LED matrix more efficient.

LED matrices can have different scanning configurations, and not all 32×16 LED matrices use a 1/4 scan pattern. While 1/4 scan is a common configuration for its efficiency, there are other scanning patterns like 1/8, 1/16, or even static configurations.

The choice of scanning pattern depends on factors such as cost, power consumption, and the complexity of the control circuitry. It’s always a good idea to check the specifications or documentation of a specific LED matrix to know its scanning configuration.
