  • Publication number: 20240105102
    Abstract: A display device includes a pixel component including first pixels which emits light having a first color, and second pixels which emits light having a second color different from the first color, a sensing component which extracts, during a sensing period, first sensing data from the first pixels, and second sensing data from the second pixels, and a temperature determiner which senses a temperature of the pixel component using the first sensing data and the second sensing data. The temperature determiner senses, when the first sensing data is supplied to the temperature determiner, the temperature of the pixel component at least one time.

  • Patent number: 7986169
    Abstract: A comparator circuit. A comparator circuit may include a differential amplifying unit to amplify a difference between a voltage at a first node and a voltage at a second node and/or output a resultant voltage, and/or a current source to supply a first bias current to a first node and/or supply a second bias current to a second node. A comparator may include a first bias switch to bias a current flowing from a first node to a ground voltage source, a second bias switch to bias a part of a current flowing from a second node to a ground voltage source, a third bias switch to bias a remaining part of a current flowing from a second node to a ground voltage source, and/or a bias converting unit to supply a third bias current to a second node.

  • Publication number: 20100164679
    Abstract: An integrated circuit includes a first inner circuit including at least one first semiconductor device, a second inner circuit including at least one second semiconductor device, and a fusing circuit connected between the first inner circuit and the second inner circuit to perform a fusing operation which electrically disconnects the first inner circuit from the second inner circuit through a fusing voltage. The fusing circuit bypasses a spark current occurring during the fusing operation to a ground power source so as not to flow the spark current into the first inner circuit and the second inner circuit.

  • Patent number: 6194861
    Abstract: A circuit for driving a sensorless BLDC motor is disclosed which checks whether or not the motor is rotating and then terminates the start up interval (or forced drive interval) in order to obtain efficient motor drive. The present invention is comprised of a comparator which receives a phase voltage through a first input terminal and receives a neutral point voltage through a second input terminal, and a flip-flop unit which is comprised of a plurality of flip-flop devices. Each flip-flop device is a means for receiving an output of the comparator through a clock signal input terminal, and a reset signal through a reset signal input terminal. The sensorless BLDC motor operates in a running mode when data provided to the input terminal of the first flip-flop means is output from the output terminal of the last flip-flop.
