Abstract

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.

First claim

What is claimed is:

1. A circuit device comprising:
an interface unit that receives display data;
a data processing unit that performs data processing on the display data; and
a drive unit that drives a display panel based on the display data subjected to the processing in the data processing unit, wherein
the data processing unit performs data processing in which the display data 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 a same pixel,
the drive unit drives the display panel based on the display data set to the first color component channel, the second color component channel, and the third color component channel,
a monochrome display mode and a color display mode can be set,
the data processing unit, in a case where the monochrome display mode is set, performs data processing in which the display data that has been input to the first color component input channel of the interface unit is set to the first color component channel, the second color component channel, and the third color component channel of the pixel, and
in a case where the color display mode is set, performs data processing in which the display data that has been input to the first color component input channel of the interface unit is set to the first color component channel of the pixel, the display data that has been input to the second color component input channel of the interface unit is set to the second color component channel of the pixel, and the display data that has been input to the third color component input channel of the interface unit is set to the third color component channel of the pixel.

2. The circuit device according to claim 1 , wherein the drive unit drives a first subpixel that constitutes the pixel based on the display data set to the first color component channel, drives a second subpixel that constitutes the pixel based on the display data set to the second color component channel, and drives a third subpixel that constitutes the pixel based on the display data set to the third color component channel.

3. The circuit device according to claim 1 , further comprising a terminal or a mode setting unit for setting the monochrome display mode or the color display mode.

4. The circuit device according to claim 1 , further comprising:
a first color component input terminal for inputting the display data for the first color component input channel to the interface unit;
a second color component input terminal for inputting the display data for the second color component input channel to the interface unit; and
a third color component input terminal for inputting the display data for the third color component input channel to the interface unit, wherein
the data processing unit, in a case where the monochrome display mode is set, performs data processing in which the display data that has been input to the first color component input terminal is set to the first color component channel, the second color component channel, and the third color component channel of the pixel.

5. The circuit device according to claim 4 , further comprising
a first terminal setting mode and a second terminal setting mode, wherein
the interface unit, in the first terminal setting mode, accepts the display data input to the first color component input terminal, and does not accept the display data input to the second color component input terminal and the third color component input terminal,
the interface unit, in the second terminal setting mode, accepts the pieces of display data input to the first color component input terminal, the second color component input terminal, and the third color component input terminal, and
in a case where the monochrome display mode is set in the first terminal setting mode, the data processing unit performs data processing in which the display data input to the first color component input terminal as the display data for the first color component input channel is set to the first color component channel, the second color component channel, and the third color component channel of the pixel.

6. The circuit device according to claim 5 , wherein, in a case where the monochrome display mode is set in the second terminal setting mode, the data processing unit performs data processing in which the pieces of display data that have been input to the first color component input channel, the second color component input channel, and the third color component input channel of the interface unit are respectively set to the first color component channel, the second color component channel, and the third color component channel of the pixel.

7. The circuit device according to claim 1 , wherein the interface unit is an interface unit that receives the display data conforming to differential input.

8. An electro-optical device comprising:
the circuit device according to claim 1 , and
the display panel.

9. An electronic apparatus comprising the circuit device according to claim 1 .
