A color light-emitting diode and a resistor are connected in series to form a basic unit, and several basic units can be connected in series, parallel, or mixed; multiple color light-emitting diodes are installed on a plane in the form of an array to form a color light emitting diode. Diode electric dot matrix screen, dot matrix screen has various colors, divided into single color, double color, three colors. The color light-emitting diodes are evenly distributed on the flexible circuit board in a matrix shape, and can be arranged and combined to form indicators or warning icons for luminous display.

The light-emitting diode driving circuit can adopt a discrete element driving circuit or an integrated driving circuit.

The system control circuit can be realized by using: micro-button switch control circuit; microprocessor control circuit, realized by remote control system, touch control system, light touch switch control system.

The flexible circuit board adopts a flexible circuit board with excellent performance, so the wireless charging light-emitting diode sign block can be bent, and the protective layer and the circuit are not easy to fall off.

The outer packaging transparent rubber sleeve is used to protect the circuit of the entire wireless rechargeable light-emitting diode signboard, and the entire wireless rechargeable light-emitting diode signboard circuit is firmly encapsulated in the outer packaging transparent rubber sleeve without any interface, so the wireless rechargeable light-emitting diode Signs are highly reliable waterproof and airtight, with a flat and smooth appearance.

Since the circuit of the wireless rechargeable light-emitting diode signboard of the present invention is a general circuit, it will not be described here.
