Claim:
1. A charge-sharing controlling method, suitable for a display panel comprising a plurality of sub-pixels, the charge-sharing controlling method comprising: determining whether the display panel is utilized to display a primary color screen; and if the display panel is displaying the primary color screen, prolonging an activated time of a charge-sharing circuit, the charge-sharing circuit being coupled between any two of the sub-pixels displaying the same color, adjacent to each other and having opposite polarities; if the display panel is not displaying the primary color screen, setting the activated time of the charge-sharing circuit at a first time length; and if the display panel is displaying the primary color screen, setting the activated time of the charge-sharing circuit at a second time length, wherein the second time length is longer than the first time length; wherein the first time length and the second time length are positively correlated to pixel capacitances of the sub-pixels, and also positively correlated to an operational voltage level on the display panel.
