A circuit device includes an interface unit that receives pieces of display data RD, GD, and BD, a data processing unit that performs data processing on the pieces of display data RD, GD, and BD, and a drive unit that drives a display panel based on display data from the data processing unit. The data processing unit performs data processing in which the display data RD that has been input to a first color component input channel of the interface unit is set to a first color component channel, a second color component channel, and a third color component channel of the same pixel. The drive unit drives the display panel based on the display data set in the first color component channel, the second color component channel, and the third color component channel.

A control unit determines the content of a video based on an input video signal based on results of determination utilizing a monochrome determination unit and a text determination unit. Based on a display mode according to a result of the content determination, the control unit displays an image corresponding to the input video signal on a display panel.

A display apparatus includes a display driving circuit and a controller. The display driving circuit includes a data driver to sequentially drive a plurality of pixel groups during one horizontal period in a time-division manner. The pixel groups are included in each of the horizontal lines of a display panel. The controller analyzes a pattern of received image data and determines a driving sequence of the plurality of pixel groups of each horizontal line based on a result of the analysis of the pattern of received image data.
