The present disclosure provides a method for determining a pixel voltage, an electronic device, and a storage medium. The method includes: obtaining an initial color shift ratio of a sub pixel to be tested, obtaining an initial evaluation value of a preset grayscale value, and obtaining a current evaluation value of the preset grayscale value according to a current color shift ratio; comparing the initial evaluation value with the current evaluation value; and determining a standard sub pixel voltage of the sub pixel to be test according to the current color shift ratio, when the current evaluation value is greater than the initial evaluation value.
