Abstract
The present application provides a display panel and a display apparatus. The display panel includes a plurality of pixel units arranged in an array, each of the pixel units includes a pixel circuit and a light emitting element; the pixel circuit includes a data writing module, a driving module, a light emitting control module and a pre-charging module; the data writing module is configured to provide a data signal to the driving module; the driving module is configured to provide a driving current to the light emitting element; the light emitting control module is configured to selectively allow the light emitting element to enter a light emitting stage; and the pre-charging module is configured to increase a voltage of a first node to a first voltage in a non-light emitting stage, in which the first voltage is less than a light emitting threshold voltage of the light emitting element.
