Current driving control for high brightness LED matrix
A LED driving system for a LED matrix having a plurality of LEDs connected in parallel. The LED driving system includes a plurality of driving modules. Each one of the plurality of driving modules drives a corresponding one of the plurality of LEDs. Each one of the plurality of driving modules can include a local current driver receiving a reference current and providing a driving current to the corresponding one LED, and a local current tuning module receiving a U-bit current tuning command to tune the driving current for the corresponding one LED to reach a desired driving current using the U-bit current tuning command which provides a predetermined number of tuning steps ranging from 0 to 2U.
