1. A method for determining an output gray-scale value of a display panel, comprising:
fitting brightness values corresponding to multiple gray scales under a target area of the display panel to obtain a target slope value and a target deviation value;
according to the target slope value and the target deviation value, determining a reference brightness value under a target gray scale of the display panel; and
according to the reference brightness value, determining an output gray-scale value corresponding to each pixel under the target gray scale;
wherein fitting the brightness values corresponding to the multiple gray scales under the target area of the display panel to obtain the target slope value and the target deviation value comprises:
acquiring the brightness value corresponding to each pixel under the multiple gray scales to obtain multiple brightness values corresponding to each gray scale;
obtaining multiple accumulated brightness values according to the multiple brightness values corresponding to each gray scale;
determining the average brightness value corresponding to each gray scale according to the multiple accumulated brightness values; and
determining the target slope value and the target deviation value according to the average brightness value corresponding to each gray scale.
