A display device includes a pixel circuit configured to generate a driving current based on a data signal supplied to a data line, a first light-emitting stage configured to emit light based on the driving current, and including first light-emitting elements connected in parallel, a detector configured to detect voltages of respective ends of the first light-emitting stage, and a current compensator configured to compensate for a current flowing through the first light-emitting stage based on a first voltage difference between the voltages of the respective ends of the first light-emitting stage.

Display device and method of driving the same

A display device includes pixels electrically connected to a plurality of scan lines and a plurality of data lines, respectively, a scan driver that provides a scan signal to each of the plurality of scan lines, a voltage supply that supplies a first gate voltage to the scan driver through a first gate power line, and a voltage compensator. The voltage compensator senses a partial voltage of the first gate voltage applied to the scan driver through a feedback line. The voltage compensator compensates the first gate voltage with a second gate voltage in case that the sensed first gate voltage is greater than a first reference voltage.

A method of controlling a washing machine and a motor determines whether a BLDC motor is in a normal state in software without hardware and a user is notified of an abnormal state of the BLDC motor if the BLDC motor is in an abnormal state, thereby ensuring safety. When the motor is rotated, the state of the motor is determined by applying harmonics to a voltage that is applied to a motor and analyzing an output frequency characteristic. When the motor is stopped, the state of the motor is determined by estimating the temperature of the motor.
