Auxiliary display device for led modules with dual voltage
The patent US12045537B1 describes an auxiliary display device designed for light-emitting diode (LED) modules, featuring a shared hub with a dual input port and an independent output port. The dual input port is capable of receiving two supply voltages, while the output port connects to either a common anode or common cathode LED module. Each module consists of two LEDs, with specific configurations for voltage supply: the first LED of the common anode module and the second LED of the same module receive the first voltage, while the first LED of the common cathode module receives the first voltage and the second LED receives the second voltage. Additional claims detail the inclusion of a dual output power source, a black screen control circuit, and various components such as switch circuits and filter circuits that enhance the device's functionality.
Further claims elaborate on the black screen control circuit, which includes switch circuits and a driver that manages power supply to the LED modules. The circuit is designed to cut off power when a standby instruction is received, indicating a lack of display signal. The patent also outlines the structure of the LED display, which incorporates the auxiliary display device along with the common anode and common cathode LED modules, each equipped with constant current chips to regulate power to the LEDs. This configuration aims to improve the efficiency and control of LED displays, ensuring optimal performance under varying operational conditions.
