Apparatus and Method for Powering LED Driver

摘要

A driver circuit for an LED display panel has a first constant current driver to drive green LEDs, a second constant current driver to drive blue LEDs, and a third constant current driver to drive red LEDs. The driver circuit also has an analog power module electrically coupled to the first, the second, and the third constant current drivers. The analog power module has two or more power sources. The driver circuit further includes a digital controller for transmitting digital control signals to the analog driver. The digital controller is powered by a digital power module.
