Display device, display system, and display driving method

A display device comprising:

• a reception circuit that is configured to receive a piece of first image data and a piece of second image data, the piece of first image data representing an entire image having a first resolution, the piece of second image data representing a first partial image having a second resolution higher than the first resolution, and the first partial image corresponding to a portion of the entire image;
• a display section including a plurality of pixels;
• a display drive circuit that is configured to perform first driving and second driving, the first driving in which the plurality of pixels is driven in units of a first number of pixels on a basis of the piece of first image data, the second driving in which two or more pixels provided in a region corresponding to the first partial image of the plurality of pixels are driven in units of a second number of pixels on a basis of the piece of second image data, and the second number being smaller than the first number;
• and
• a decompression circuit that is configured to decompress a piece of compressed image data of the piece of first image data and the piece of second image data, wherein
• both the piece of first image data and the piece of second image data are compressed, and a compression ratio of the piece of first image data and a compression ratio of the piece of second image data are different from each other.

A display system comprising:

• an image generation device that is configured to transmit a piece of first image data and a piece of second image data, the piece of first image data representing an entire image having a first resolution, the piece of second image data representing a first partial image having a second resolution higher than the first resolution, and the first partial image corresponding to a portion of the entire image;
• and
• a display device,
• the display device including
• a reception circuit that is configured to receive the piece of first image data and the piece of second image data,
• a display section including a plurality of pixels,
• a display drive circuit that is configured to perform first driving and second driving, the first driving in which the plurality of pixels is driven in units of a first number of pixels on a basis of the piece of first image data, the second driving in which two or more pixels provided in a region corresponding to the first partial image of the plurality of pixels are driven in units of a second number of pixels on a basis of the piece of second image data, the second number being smaller than the first number, and
• a decompression circuit that is configured to decompress a piece of compressed image data of the piece of first image data and the piece of second image data, wherein
• at least one of the piece of first image data or the piece of second image data is compressed.

A display driving method comprising:

• transmitting a piece of first image data and a piece of second image data, the piece of first image data representing an entire image having a first resolution, the piece of second image data representing a first partial image having a second resolution higher than the first resolution, the first partial image corresponding to a portion of the entire image;
• receiving the piece of first image data and the piece of second image data;
• performing first driving in which a plurality of pixels is driven in units of a first number of pixels on a basis of the piece of first image data;
• and
• performing second driving in which two or more pixels provided in a region corresponding to the first partial image of the plurality of pixels are driven in units of a second number of pixels on a basis of the piece of second image data, the second number being smaller than the first number;
• and
• decompressing a piece of compressed image data of the piece of first image data and the piece of second image data, wherein at least one of the piece of first image data or the piece of second image data is compressed.
