1. A method for debugging a display panel, comprising:
acquiring a target correction data table of the display panel in each of at least one color mode by debugging the display panel in each of the at least one color mode, and
wherein debugging the display panel in each of the at least one color mode comprises:
controlling the display panel to display a test picture in the color mode;
acquiring an initial display parameter curve of the display panel in the color mode based on a display parameter of the test picture;
detecting whether a data processing unit in the display panel turns off a processing function;
acquiring a standard display parameter curve of the display panel in the color mode based on preset standard information, in response to the data processing unit turning off the processing function, or
acquiring the standard display parameter curve of the display panel in the color mode based on an initial display parameter deviation and preset standard information, in response to the data processing unit turning on the processing function, wherein the initial display parameter deviation is a deviation between the initial display parameter curve of the display panel in the color mode when the data processing unit is in a state that the processing function is turned on and the initial display parameter curve of the display panel in the color mode when the data processing unit is in a state that the processing function is turned off;
determining a reference display parameter curve of the display panel in the color mode based on the initial display parameter curve and the standard display parameter curve of the display panel in the color mode; and
determining the target correction data table of the display panel in the color mode based on the reference display parameter curve and the standard display parameter curve.
