Abstract:
1. An integrated circuit device comprising: a data driver that drives a plurality of data lines of an electro optical device; and a data distribution circuit that supplies data to the data driver, wherein the data driver includes an odd numbered data line driver circuit for driving odd numbered data lines among the plurality of data lines, an even numbered data line driver circuit for driving even numbered data lines among the plurality of data lines, an odd numbered data line latch circuit provided for the odd numbered data line driver circuit, and an even numbered data line latch circuit provided for the even numbered data line driver circuit; and the data line distribution circuit, upon receiving time serially inputted image data, supplies odd numbered data line image data for the number of multiplexes to the odd numbered data line latch circuit, and supplies even numbered data line image data for the number of multiplexes to the even numbered data line latch circuit; wherein the odd number data line latch circuit latches the odd numbered data line image data, and supplies the odd numbered data line image data to the odd numbered data line driver circuit; the odd numbered data line driver circuit, upon receiving the odd numbered data line image data, outputs a multiplexed odd numbered data line data signal; the even numbered data line latch circuit latches the even numbered data line image data, and supplies the even numbered data line image data to the even numbered data line driver circuit; and the even numbered data line driver circuit, upon receiving the even numbered data line image data, outputs a multiplexed even numbered data line data signal, wherein demultiplexed data signals obtained by demultiplexing the multiplexed odd numbered data line data signal by a demultiplexer are supplied to corresponding ones of the odd numbered data lines in one horizontal scanning period, and demultiplexed data signals obtained by demultiplexing the multiplexed even numbered data line data signal by the demultiplexer are supplied to corresponding ones of the even numbered data lines in one horizontal scanning period.
