Adjustment of display panel

A display terminal, comprising:

• a display panel;
• a processor;
• and
• a memory electrically connected to the processor and storing a plurality of application programs;
• wherein the processor is configured to execute the application programs to implement an adjustment method of the display panel comprising:
• obtaining one or more gamma voltages respectively corresponding to one or more first binding points as one or more first gamma voltages, the first binding points being binding points of an extreme grey scale of the display panel;
• obtaining one or more gamma voltages respectively corresponding to one or more second binding points as one or more second gamma voltages, the second binding points being binding points of a secondary grey scale of the display panel, wherein the secondary grey scale is adjacent to the extreme grey scale in a preset display grey scale table;
• adjusting the one or more gamma voltages corresponding to the one or more second binding points based on the one or more first gamma voltages and the one or more second gamma voltages to obtain one or more target gamma voltages of the one or more second binding points;
• and
• adjusting a grey scale value of the extreme grey scale in a preset grey scale-accurate color capture look-up table (ACC LUT) of the display panel, so that a brightness value of the secondary grey scale in the preset grey scale-ACC LUT reaches a target brightness value, the target brightness value being a brightness value of the extreme grey scale.
