Abstract
A display driver includes: a memory comprising a plurality of memory regions each configured to store image data for one line of an image displayed in a frame; and control circuitry configured to adjust a number of in-use memory regions of the plurality of memory regions used to store the image data. The control circuitry is further configured to control the memory so that image data for respective lines of the image are cyclically stored in the in-use memory regions in a fixed order.
Claims20
A display driver, comprising:
- a memory comprising a plurality of memory regions, each of the plurality of memory regions configured to store image data for one line of an image displayed in a frame;
- and
- control circuitry configured to:
- adjust a number of in-use memory regions of the plurality of memory regions that are used to store the image data;
- and
- control the memory so that image data for respective lines of the image are cyclically stored in the in-use memory regions in a fixed order.
A display device, comprising:
- a display panel;
- and
- a display driver comprising:
- a memory comprising a plurality of memory regions, each of the plurality of memory regions configured to store image data for one line of an image displayed in a frame;
- control circuitry configured to:
- adjust a number of in-use memory regions of the plurality of memory regions that are used to store the image data;
- and
- control the memory so that image data for respective lines of the image are cyclically stored in the in-use memory regions in a fixed order;
- and
- drive circuitry configured to receive the image data stored in the memory and drive the display panel based on the image data.
A method of operating a display driver comprising a plurality of memory regions, each of the plurality of memory regions configured to store image data for one line of an image displayed in a frame, the method comprising:
- adjusting a number of in-use memory regions of the plurality of memory regions that are used to store the image data;
- and
- controlling the memory so that image data for respective lines of the image are cyclically stored in the in-use memory regions in a fixed order.
