1. An adjusting method for a display panel, comprising:
acquiring a detection coordinate value of a white point of the display panel in operation;
determining a target adjustment mode from at least two adjustment modes according to the detection coordinate value, wherein the at least two adjustment modes comprise a first adjustment mode and a second adjustment mode; and
adjusting at least some parameters of the display panel on a basis of the target adjustment mode, wherein the at least some parameters of the display panel comprise a grayscale coefficient and a white point setting position, adjusting the grayscale coefficient and taking the detection coordinate value as the white point setting position in the first adjustment mode, and adjusting the grayscale coefficient and adjusting the white point setting position according to the detection coordinate value in the second adjustment mode;
