The invention discloses a level shifting circuit and a control method thereof, a display device and a driving circuit thereof. The level shifting circuit and the control method thereof, the display device and the driving method thereof belong to the field of displaying technology. The level shifting circuit comprises a level shifting module and a detecting module, wherein the detecting module is connected with a signal output end and the level shifting module for detecting whether a signal which is output from the signal output end satisfies a normal output condition. When incapability of satisfying a normal output condition is detected, a feedback signal in a first level can be output to the level shifting module. The level shifting module can forbid signal outputting to the signal output end according to the feedback signal. According to the level shifting circuit and the control method thereof, the display device and the driving method thereof, whether the output signal satisfies a normal condition is detected through setting the detecting module. The level shifting circuit, the control method thereof, the display device and the driving method thereof settle problems of single overcurrent protecting chip testing mode, relatively low protecting effect and effective protection for a gate driving circuit. The level shifting circuit, the control method thereof, the display device and the driving method thereof are used for displaying images.
