A gamma correction method of a display device determines a first voltage code for a first color corresponding to each gradation based on a target gamma value and a target color coordinate at a reference measurement point, and generates a first lookup table including the first voltage code for the first color. Determining a second voltage code for the first color corresponding to each gray scale based on the target gamma value and the target color coordinate at a correction measurement point; a first color position correction value is generated based on the first voltage code for the first color and the second voltage code for the first color, and gamma correction is performed using the first color position correction value and the first lookup table. 显示装置的伽马补正方法在基准测量点中基于目标伽马值和目标色坐标来决定与各个灰度对应的对于第一颜色的第一电压代码，生成包括对于所述第一颜色的所述第一电压代码的第一查找表，在补正测量点中基于所述目标伽马值和所述目标色坐标来决定与所述各个灰度对应的对于所述第一颜色的第二电压代码，基于对于所述第一颜色的所述第一电压代码和对于所述第一颜色的所述第二电压代码来生成第一颜色位置补正值，利用所述第一颜色位置补正值和所述第一查找表来执行伽马补正。
