Drive method for controlling data voltage of display panel, and display apparatus including source drive circuit for controlling data voltage of display panel

A display apparatus, comprising:

• a display panel, comprising a source drive circuit;
• and
• a timing controller, configured to:
• convert, in a condition that current original gray-scale values corresponding to sub-pixels in a same region are the same in a plurality of continuous display frames, the current original gray-scale values into a first target gray-scale value and a second target gray-scale value;
• and
• output the first target gray-scale value and the second target gray-scale value to the source drive circuit;
• wherein the first target gray-scale value is greater than each of the current original gray-scale values, and the second target gray-scale value is smaller than the current original gray-scale values;
• wherein the source drive circuit is configured to:
• in a current display frame of the plurality of continuous display frames;
• control a data voltage corresponding to the first target gray-scale value to be input to a first sub-pixel unit in the region;
• and
• control a data voltage corresponding to the second target gray-scale value to be input to a second sub-pixel unit in the region;
• and
• in a next display frame of the plurality of continuous display frames;
• control the data voltage corresponding to the second target gray-scale value to be input to the first sub-pixel unit in the region;
• and
• control the data voltage corresponding to the first target gray-scale value to be input to the second sub-pixel unit in the region;
• wherein the first sub-pixel unit and the second sub-pixel unit are adjacent to each other;
• and each of the first sub-pixel unit and the second sub-pixel unit comprises at least one sub-pixel.
