Abstract: A voltage converting circuit, a voltage converting method, a gate driving circuit, a display panel and a display device are provided. The voltage converting circuit includes: a control sub-circuit and an output sub-circuit. The control sub-circuit is configured to output first conversion control signal to the output sub-circuit when input terminal of the control sub-circuit receives first voltage signal, and output second conversion control signal to the output sub-circuit when the input terminal of the control sub-circuit receives second voltage signal; and the output sub-circuit is configured to output third voltage signal when receiving the first conversion control signal from the control sub-circuit, and output fourth voltage signal when receiving the second conversion control signal from the control sub-circuit. Thus, the voltage conversion circuit can not only convert the first voltage signal into the third voltage signal but also convert the second voltage signal into the fourth voltage signal.

Abstract: The present disclosure provides a display panel driving circuit, including: a master source driving circuit, a slave source driving circuit, and a gate electrode driving circuit. The master source driving circuit is configured to convert an input control signal from an external display control board to a first data-driving control signal and a first gate-driving control signal, and convert a first data signal from the external display control board to a second data signal. The slave source driving circuit is coupled to the master source driving circuit and data lines of a display panel, and is configured to receive the first data-driving control signal and the second data signal. The gate electrode driving circuit is coupled to the master source driving circuit and gate lines of the display panel, and is configured to receive a first gate-driving control signal.

Abstract: 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.
