1. A method for adjusting brightness of a screen, comprising:
determining corresponding at least one target gamma bonding node group based on corresponding adjusted register values of a color channel of a sample pixel in a sample screen under different initial gamma bonding nodes and different refresh frequencies;
for each target pixel in a target to-be-adjusted target screen, according to the corresponding adjusted register value of the color channel of the target pixel under different first combined display conditions, obtaining a first mapping function between a corresponding register value of the color channel of the target pixel when a reference refresh frequency is used as a display condition and a corresponding register value of the color channel of the target pixel when a target refresh frequency is used as the display condition, wherein a first combined display condition is obtained by combining target gamma nodes in the at least one gamma bonding node group and refresh frequencies of the reference refresh frequency and the target refresh frequency;
for remaining gamma bonding nodes except the target gamma bonding nodes and according to the first mapping function and the adjusted register value of the color channel of the target pixel under the remaining gamma bonding nodes and the reference fresh frequency, determining a corresponding calculated register value of the color channel of the target pixel under the remaining gamma bonding nodes and the target refresh frequency; and
according to the corresponding calculated register value of the color channel of the target pixel under the remaining gamma bonding nodes and the target refresh frequency, adjusting the display brightness of the target screen at the target refresh frequency.
