The display panel includes multiple pixel units arranged in an array, a pixel unit including multiple sub-pixels, a sub-pixel including a pixel drive circuit and a light emitting element connected with the pixel drive circuit, the display panel further including an initial signal generator, the display panel including a low frequency driving mode and a normal driving mode, the low frequency driving mode including a refresh frame stage for writing data to the pixel unit and a hold frame stage for holding the data written to the pixel unit, the initial signal generator being configured to acquire a current display brightness value band and a pattern to be displayed in the low frequency driving mode; quantize the pattern to be displayed to get an average picture level; determine a corresponding anode reset voltage according to the current display brightness value band and the average picture level.

Initial signal generator, display panel and display method thereof, and display apparatus

A method for controlling voltage output is disclosed. The method is used to control a power supply module to provide a required operating voltage to a display panel, and a display frame of the display panel comprises a plurality of sequential row driving periods, each row driving period comprising a charging period and a non-charging period, wherein during the charging period, a connection between a data line and a corresponding row of sub-pixels is enabled so that data voltages are written into the corresponding sub-pixels. The method comprises controlling the power supply module to output an operating voltage at a preset first operating frequency during a display of a picture to be displayed, wherein a time period during which the power supply module outputs the operating voltage to the display panel does not overlap with the charging period of each row driving period.
