Abstract
The embodiments of present application discloses a display panel and a display apparatus. The display panel includes a pixel circuit including a driving transistor and a data writing module; a data signal line connected to the data writing module and used to provide a data signal to the pixel circuit; and a voltage control module connected to the data signal line; wherein a low-frequency data refresh cycle includes a number of data frames including a data writing frame and n holding frames; in the data writing frame, the data signal line writes the data signal into the driving transistor; in the holding frames, the data signal line does not write the data signal; in first m holding frames, the voltage control module controls the data signal line to be maintained at a first voltage value V1, V1<V2, V2 is a preset data voltage value, and n≥m≥1.
