摘要： A level shift circuit, control method thereof, a display device and a drive circuit thereof are provided. The level shift circuit includes a level shift sub-circuit and a detection sub-circuit. The detection sub-circuit is connected to a signal input end and the level shift sub-circuit, and is configured to detect whether the signals output by the signal output end meet the normal output condition or not. A feedback signal with a first level may be output to the level shift sub-circuit when signals output by the signal output end are detected not to meet the normal output condition. The level shift circuit may stop outputting the signals to the signal output end according to the feedback signal. By arranging the detection sub-circuit to detect whether the output signal meets the normal condition, the gate drive circuit may be effectively protected.

摘要： The present disclosure provides a level shifting unit which includes, for example, a logic control module, an output module, an output control module and a feedback module. The logic control module is connected to a turn-on power supply, a driving power supply, an input signal terminal, and the output module. The feedback module is connected to an enable signal terminal, a signal output terminal, and the output control module. The output control module is connected to the output module and the driving power supply. The output module is connected to the signal output terminal. The feedback module controls to turn on or turn off the output module through the signals outputted from the enable signal terminal and the signal output terminal. If the signals outputted by two level shifting units are short circuited, the feedback module controls the output control module of the level shifting circuit to be disconnected.

摘要： The embodiments of the disclosure provide a mobile terminal, which includes a power generation unit, a power storage unit and a control system. The power generation unit includes a toroidal inductance coil which can move back and forth inside and outside a region of magnetic field generated by a permanent magnet and incise magnetic force lines of the permanent magnet, such that a current is generated in the toroidal inductance coil. The power storage unit is connected with the toroidal inductance coil of the power generation unit and a power supply circuit of the mobile terminal, respectively, and the power storage unit is used for storing power generated by the power generation unit. The control system is connected with the power storage unit. When electricity of a battery of the mobile terminal is less than a predetermined amount and the battery is not in a charged state, the control system causes the power storage unit to supply power to the mobile terminal.
