Method and device for LED channel managment in LED driver

摘要: Disclosed are example open channel detection techniques at a light emitting diode (LED) driver of an LED system. The does not enable its channels before normal operation so as to inhibit current flow through the during start-up. While disabled, compares voltages inputs with predetermined voltage determine whether operational string associated panel is connected channel. In event that determined be “open” channel, further disables for following mode. Otherwise, if string, enables mode, which can selectively activated output subject display data panel.
