Abstract
The application discloses a level conversion circuit and a display panel. The level conversion circuit comprises a first conversion branch, a second conversion branch and a driving controller. The second conversion branch with lower conduction resistance and the first conversion branch with higher conduction resistance are controlled to be in a conduction state at different times in a level conversion stage and a conduction maintenance stage. The level conversion circuit can not only improve the switching speed between levels in the level conversion stage, but also reduce the current due to the lower conduction resistance, thereby reducing the power consumption and the heat generation. In addition, the driving capacity required in the conduction maintenance stage is reduced, and the power consumption can also be reduced.
