Voltage adjusting method for a display panel and related computer readable medium

The present disclosure provides method and a computer readable medium for adjusting voltage applied on a display panel. The present disclosure could utilize the ratio of Vgs of two different tests, as an adjustment factor, to compensate the voltage value of each display area. Thus, the method could obtain the same compensation voltage for different display area to compensate the voltage difference between the node G and the node S. This could reduce the influence of the output step. In addition, the method could further detect the inputted compensation voltage to obtain a current value according to a second adjusting step. Through the current formula, the ratio of constant k of each display area could be obtained to adjust the threshold value of the TFT according to the current formula such that the current of each display area could be consistent.
