  • Patent number: 8842405
    Abstract: An electronic device that is capable of detecting an abnormal state such that a switching element is unable to be turned off in spite of a drive signal instructing turn-off of the switching element. The device includes a switching element that is driven by controlling a voltage on its control terminal, a drive circuit that controls the voltage on the control terminal of the switching element on the basis on an inputted drive signal to drive the switching element. In cases where there exists a current flowing through the switching element in spite of the drive signal instructing turn-off of the switching element, the drive circuit determines that the switching element is in an abnormal state, and cuts off supply of voltage from a drive power supply circuit to the control terminal of the switching element to thereby turn off the switching element.

  • Patent number: 8687327
    Abstract: An electronic system has IGBT, on driving FET and off driving FET connected with the gate of the IGBT, and a control circuit. The on driving FET in an on state supplies electric charge to the IGBT gate. The off driving FET in an on state releases the charge from the GET gate. The control circuit controls each of the on FETs according to a driving signal to be set in the on and off states every switching period of time and to control the voltage at the IGBT gate. When on-failure occurs in the on driving FET set in the on state so as to keep the on driving FET in the on state in spite of control of the control circuit, the control circuit controls a controlled element other than the off driving FET to set the IGBT in the off state.

  • Patent number: 8638283
    Abstract: A timing controller is provided which is capable of achieving normal image display at a time of reverse scanning in upward and downward directions and right and left directions. In an image display device having a plurality of scanning line driving ICs (Integrated Circuits), a valid line counting section counts a count of valid driving lines based on a DE (Data Enable) signal and DCK (Dot Clock) signal. A cascade signal counting section counts up a total count of outputs from a count of VCK (Vertical Clock) signals including a VSP (Vertical Start Pulse) 2 output signal up to a VSP1 cascade outputting signal VSP1. A calculating section calculates an excessive output of a scanning line driving IC from a difference between the count of valid driving lines and the total count of outputs.

    Abstract: A liquid crystal display device employing an AC driving method is provided which is capable of minimizing a period of time during which a difference in magnitude between a positive voltage and a negative voltage relative to an intermediate potential occurs in gray-level reference voltages making up AC driving voltages when AC voltages are changed during operations of the liquid crystal display device by selecting an optimized order of outputting the gray-level reference voltages generated by a sequential switching method. An output switching control section is provided in a gray-level reference voltage generating section which outputs, at a time of changing the gray-level reference voltages during operations of the device, the gray-level reference voltage to a source driver in an order being different from an order of having received the gray-level reference voltage input from a same output voltage setting section after being sequentially switched.
