  • Virtual load board and test system and test method for liquid crystal display control board
    Patent number: 9430957
    Abstract: A virtual load board includes a connection port, a conversion circuit, and an indication unit, wherein the connection port comprises at least one terminal. The terminal receives an output voltage from the liquid crystal display control board. The conversion circuit converts the output voltage into an operating voltage for the indication unit and supplies the operating voltage to the indication unit. A test system and a test method for liquid crystal display control board are also provided. With the above-discussed arrangement, the virtual load board replaces a liquid crystal display panel to carry out a reliability test of the liquid crystal display control board, and has the advantages of small volume and low cost and can be accommodated, together with the liquid crystal display control board, in reliability test equipment in order to carry out a reliability test of the liquid crystal display control board in a specific environment.
