  • Patent number: 10033355
    Abstract: A voltage adjustment circuit includes switches connected in parallel between a circuit unit and an electric power supply line to which a first electric power supply voltage is applied, and changes the number of switches turned off, based on a comparison result between a target value and a second electric power supply voltage supplied to the circuit unit, to adjust the second electric power supply voltage. A control circuit decides an interval for increasing the number of switches turned off when the circuit unit changes to standby state, based on a leak current value of the circuit unit in standby state, a time in which the second electric power supply voltage changes from a first to a second value, the first and second values, and an electric potential difference by which the second electric power supply voltage changes when one switch switches between on and off.

  • Patent number: 8963161
    Abstract: In a semiconductor device, gate signal lines are spaced apart from each other above a crystalline semiconductor film. Therefore a first protective circuit is not electrically connected when contact holes are opened in an interlayer insulating film. The static electricity generated during dry etching for opening the contact holes moves from the gate signal line, damages a gate insulating film, passes the crystalline semiconductor film, and again damages the gate insulating film before it reaches the gate signal line. As the static electricity generated during the dry etching damages the first protective circuit, the energy of the static electricity is reduced until it loses the capacity of damaging a driving circuit TFT. The driving circuit TFT is thus prevented from suffering electrostatic discharge damage.
