Abstract
A display device includes a display panel including a plurality of pixels, and a panel driver configured to receive input data, and to drive the display panel based on the input data. The panel driver includes a partial still image detector configured to detect a still image data portion in the input data by determining whether at least a portion of the input data represents a still image, and a command decoder configured to extract command data from the input data by decoding the still image data portion in which the command data are encoded.
Claims20
A display device comprising:
- a display panel comprising a plurality of pixels;
- and
- a panel driver configured to receive input data, and to drive the display panel based on the input data,
- wherein the panel driver comprises:
- a partial still image detector configured to detect a still image data portion in the input data by determining whether at least a portion of the input data represents a still image;
- and
- a command decoder configured to extract command data from the input data by decoding the still image data portion in which the command data are encoded.
A method of receiving image data and command data by a display device, the method comprising:
- receiving input data comprising the image data;
- detecting a still image data portion in the input data by determining whether at least a portion of the input data represents a still image;
- storing the still image data portion;
- receiving the input data comprising the image data in which the command data are encoded in the still image data portion;
- and
- extracting the command data from the input data by calculating a difference between the stored still image data portion and the still image data portion in which the command data are encoded.
A method of transferring image data and command data to a display device by a host processor, the method comprising:
- transferring input data comprising the image data to the display device;
- identifying a still image data portion in the input data;
- encoding the command data in the still image data portion;
- and
- transferring the input data comprising the image data in which the command data are encoded in the still image data portion to the display device.
