1. A method for reducing a color edge phenomenon of a display panel, applicable to a display panel comprising a plurality of pixel units, and the method comprising:
performing pixel adjustment on the pixel units at edges of the display panel, wherein each pixel unit comprises at least three sub-pixels: a first sub-pixel, a second sub-pixel, and a third sub-pixel, to adjust positions, areas, or brightness of the sub-pixels;
wherein pixel adjustment on the pixel units at edges of the display panel comprises eliminating a red edge generated by a first edge of the display panel, a green edge generated by a second edge of the display panel, a yellow edge generated by a third edge of the display panel, and a blue edge generated by a fourth edge of the display panel by reducing the brightness of the sub-pixels at the edges of the display panel; and
wherein the sub-pixels with the reduced brightness comprise:
the first sub-pixel at the first edge of the display panel and the third sub-pixel at the second edge of the display panel for horizontal compensation of the brightness; and
the first sub-pixel and the third sub-pixel at the third edge of the display panel and the second sub-pixel at the fourth edge of the display panel for vertical compensation of the brightness.
