摘要：
In an exemplary RGBW display apparatus, a plurality of four-color image output signals and a plurality of mapping scale ratios are generated according to a plurality of three-color image input signals. Furthermore, a backlight output intensity outputted from a backlight module is dynamically adjusted according to the mapping scale ratios and a white color signal adjust ratio is generated. In addition, a white color signal in each of the four-color image output signals is adjusted to be an updated white color signal according to the white color signal adjust ratio.
