A method for safely operating and controlling an electric motor in an electric vehicle is provided. The method includes the steps of: obtaining first battery power information provided by a BMS when the vehicle is running; measuring second battery power information according to motor torque depending on the driver's pedal opening in each driving condition; comparing the first battery power information with the second battery power information with each other; determining whether the motor is abnormal based on the comparison result; and when the motor is determined to be abnormal, performing control of gradually limiting the motor output.

This disclosure relates to a display device, a method for manufacturing the display device, and an electronic device. The display device includes: a display panel including: a main region; and a sub-region disposed on one side of the main region and configured to be bendable; and a cover window including: a substrate layer disposed on the display panel; a coating layer disposed on the substrate layer; a first residual trace disposed on a first side of the cover window adjacent to the sub-region; and a second residual trace disposed on at least one of the remaining sides of the cover window other than the first side.

According to one aspect of this disclosure, a display device includes: a substrate, the substrate including a display area, a first non-display area surrounding the display area, a curved area extending from the first non-display area, and a second non-display area extending from the curved area; a first planarization layer disposed on the substrate in the first non-display area, the curved area, and the second non-display area; a plurality of connecting lines located on the first planarization layer in the first non-display area, the curved area, and the second non-display area; and a second planarization layer located on the plurality of connecting lines in the first non-display area, the curved area, and the second non-display area, and in cross-section, the plurality of connecting lines are configured to be closer to the substrate in the central portion of the curved area than at the boundary between the first non-display area or the second non-display area and the curved area.

A gate-drive controller for a power semiconductor device includes a master control unit (MCU) and one or more comparators that compare the output signal of the power semiconductor device to a reference value generated by the MCU. The MCU, in response to a turn-off trigger signal, generates a first intermediate drive signal for the power semiconductor device and generates a second intermediate drive signal, different from the first drive signal, when a DSAT signal indicates that the power semiconductor device is experiencing de-saturation. The MCU generates a final drive signal for the power semiconductor when the output signal of the one or more comparators indicates that the output signal of the power semiconductor device has changed relative to the reference value. The controller may also include a timer that causes the drive signals to change in predetermined intervals when the one or more comparators do not indicate a change.
