Calculate based on the duty cycle of your multiplexing scheme. If you are driving one row at a time, the peak current must be higher to maintain perceived brightness, but it must remain within the pulse-width limits specified in the datasheet.
LED Dot Matrix & Cluster Modules Component Intelligence
Engineering-grade LED matrix modules for high-contrast visual feedback and industrial display interfaces.
What are LED Dot Matrix & Cluster Modules components?
LED dot matrix and cluster modules provide scalable, high-contrast visual output for embedded systems. Selection hinges on pixel pitch, drive current, forward voltage, and the required interface protocol (e.g., SPI, I2C, or direct row/column multiplexing).
How to Choose LED Dot Matrix & Cluster Modules Components
Select modules based on physical constraints and drive requirements to ensure display longevity and readability.
Pixel Pitch & Density
Determine the viewing distance to select the appropriate pixel pitch; higher density increases resolution but complicates routing.
Drive Topology
Check if the module requires external constant-current drivers or if it supports direct multiplexing via MCU GPIOs.
Luminous Intensity
Match the millicandela (mcd) rating to your ambient lighting environment to ensure sufficient contrast.
Color Consistency
Verify binning codes if matching multiple modules in a single array to prevent visible color shifts between units.
Thermal Management
High-density clusters generate significant heat; ensure the PCB layout allows for adequate thermal dissipation.
