A method for debugging the display panel includes: 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. Debugging the display panel in each of the at least one color mode includes: controlling the display panel to display a test picture in the color mode; acquiring an initial display parameter curve based on a display parameter of the test picture; determining a reference display parameter curve based on the initial display parameter curve and a standard display parameter curve; and determining the target correction data table based on the reference display parameter curve and the standard display parameter curve.
