Claim Text:
1. A virtual load board, wherein the virtual load board comprises a connection port, a conversion circuit, and an indication unit, wherein the connection port comprises at least one terminal, the terminal adapted to receive an output voltage from a liquid crystal display control board, the conversion circuit connected to a reference voltage and receiving and converting the output voltage into an operating voltage for the indication unit and supplying the operating voltage to the indication unit; wherein the conversion circuit comprises a first resistor component and a second resistor component connected in series between the terminal and the reference voltage and the indication unit has a first end directly connected to a node point between the first and second resistor components and a second end connected directly to the terminal or the reference voltage and is connected in parallel with the first resistor component or the second resistor component, which defines a division voltage that is supplied to the indication unit, whereby the indication unit is activated when the division voltage corresponds to the operating voltage of the indication unit.
