Abstract
An exemplary dimming control apparatus of generating a dimming control signal for a display area is provided. The dimming control apparatus includes a data analysis module and an output module. The display area includes a plurality of pixels. The data analysis module receives a plurality of first pixel values corresponding to the pixels, respectively, where the first pixel values correspond to a first frame; in addition, the data analysis module derives a first characteristic value corresponding to the first frame according to a distribution of the first pixel values, and generates a first dimming value according to at least the first characteristic value. The output module is coupled to the data analysis module, and generates the dimming control signal corresponding to the first frame according to at least the first dimming value.
