Abstract:
1. A display device, comprising: a timing controller, receiving input pixel data and outputting first pixel data according to the input pixel data, wherein a color depth of the first pixel data is unfixed and varied to be a first bit number or a second bit number, and the second bit number is smaller than the first bit number; and at least one data driving circuit, coupled to the timing controller, and receiving the first pixel data and a notice signal, and performing a mapping operation on the first pixel data to generate second pixel data according to the notice signal when the color depth of the first pixel data is the second bit number, and not to perform the mapping operation on the first pixel data but directly taking the first pixel data as the second pixel data when the color depth of the first pixel data is the first bit number, and generating at least one driving voltage according to the second pixel data, wherein a color depth of the second pixel data is fixed to the first bit number.
