Abstract: Embodiments of the disclosure provide a gamma voltage correction method and system for a display module. A display area of the display module includes adjacent first sub-display area and second-sub-display area, which are independently driven by different source drivers respectively. The method comprises performing gamma curve adjustment to the first sub-display area according to a target gamma curve to obtain a first data voltage corresponding to a first grayscale; driving the second sub-display area with the first data voltage so that the second sub-display area emits light; and regulating the first data voltage based on a difference in brightness between the first-sub-display area and the second-sub-display area when driven by the first data voltage respectively to obtain a second data voltage for driving the second sub-display area so as to reduce a brightness difference between the first sub-display area and the second sub-display area.
