Abstract

The present disclosure discloses a level shifter circuit and a display panel. The level shifter circuit includes a level shifter module, a compare module connected to the level shifter module. The level shifter module includes a level shifter unit, a control unit connected to the level shifter unit. The level shifter unit receives a first voltage signal and a second voltage signal and generates a level shifter result signal according to the first voltage signal and the second voltage signal. The compare module is configured to compare a voltage corresponding to the level shifter result signal with a reference voltage at a predetermined time and generate a comparison result. The control unit stops the shifter unit when the voltage corresponding to the level shifter result signal is less than the reference voltage. The present disclosure prevents the display panel from being damaged by short circuiting.
