Abstract: Display apparatuses and self-capacitance touch panels thereof are provided. A self-capacitance touch panel includes a touch wiring layer and a signal transmission wiring layer. The touch wiring layer includes a plurality of touch units arranged in an array, each of which includes a plurality of touch lines electrically connected. The signal transmission wiring layer includes a plurality of signal transmission lines extending in a row direction or a column direction, at least one of which is electrically connected with a corresponding one of the touch units and electrically insulated from the rest of the touch units in an extending direction thereof. At least a portion of an orthographic projection of the signal transmission line in a plane where the self-capacitance touch panel is located is misaligned with an orthographic projection of each of the touch lines of the touch units electrically insulated from the signal transmission line in the plane.

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.
