Display device including a plurality of sub-signal processing circuits corresponding to a plurality of video signal colors, and method of controlling display device

摘要

A display device includes a main signal processing circuit to which color video data is input, and a plurality of sub-signal processing circuits to which video data for respective colors output by the main signal processing circuit are input. The main signal processing circuit generates information, which is used when each of the sub-signal processing circuits performs a predetermined process, based on information of a plurality of colors in the color video data input, and then outputs data representing the generated information to each of the sub-signal processing circuits together with the video data for the respective colors.
