1. A method for determining a pixel voltage, comprising:
obtaining a preset grayscale value, an initial color shift ratio, and a current color shift ratio of a sub pixel to be tested;
obtaining an initial evaluation value of the preset grayscale value according to the initial color shift ratio, and obtaining a current evaluation value of the preset grayscale value according to the 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,
wherein the step of comparing the initial evaluation value with the current evaluation value further comprises:
obtaining an initial sub pixel voltage corresponding to the initial color shift ratio and a current sub pixel voltage corresponding to the current color shift ratio, when the initial evaluation value is equal to the current evaluation value;
comparing the initial sub pixel voltage with the current sub pixel voltage; and
determining the initial sub pixel voltage as the standard sub pixel voltage of the sub pixel to be test, when the initial sub pixel voltage is smaller than the current sub pixel voltage.
