Abstract: The present disclosure provides a brightness regulating method. The brightness regulating method is applied to a displaying device. The displaying device includes a backlight module. The regulating method includes: dividing a backlight source of the backlight module into a plurality of light areas; acquiring pixel quantities and pixel grayscale values of pixels within pixel areas corresponding to each of the light areas; according to the pixel quantities and the pixel grayscale values, determining brightness parameters of the light areas; and according to the brightness parameters, regulating brightnesses of the light area. Because, in the process of the brightness regulation, each of the light areas corresponds to one brightness parameter, the light areas can be individually regulated according to the severity degrees of the halo phenomenon in the different areas, whereby, while alleviating the halo phenomenon, the brightness regulation has a better pertinence and a better effect.
