  • Voltage supply unit and display device having the same
    Patent number: 9990898
    Abstract: A voltage supply unit and a display device including the voltage supply unit are provided. The voltage supply unit includes a first voltage input terminal to which a first voltage as a DC voltage is input; a second voltage input terminal to which a second voltage as an AC voltage is input; a first capacitor between a first node and the second voltage input terminal; and a current control circuit between the first voltage input terminal and the first node and controlling a current value flowing from the first voltage input terminal to the first node so as to be equal to or less than a current limit value.
    Type: Grant
