Samsung patents display driver that adaptively stores images

This patent describes an electronic device where the processor tells the display driver whether to save incoming images in its internal memory or skip that step. The driver can switch between storing and bypassing images based on signals from the processor, such as changes in refresh rate.

Why it mattersThis improves how display hardware manages data flow, potentially helping devices handle different screen speeds more efficiently.

In the filing’s own words

An example electronic device includes a display panel; a display driver circuit operably coupled to the display panel and including a memory; and a processor operably coupled to the display driver circuit. The processor may be configured to identify a refresh rate; provide, to the display driver circuit, a first signal that indicates storing in the memory one or more images to be provided from the processor for a display on the display panel according to the refresh rate, or provide, to the display driver circuit, a second signal that indicates bypassing to store the one or more images in the memory.

What exactly they claim (claim 1)

1. An electronic device comprising: at least one processor comprising processing circuitry; display driver circuitry including memory; and a display panel, wherein the display driver circuitry is configured to: while storing of an image received from the at least one processor in the memory of the display driver circuitry is activated in accordance with a first command received from the at least one processor, receive, from the at least one processor, a second command for deactivating storing of an image received from the at least one processor in the memory of the display driver circuitry; in response to a first image received initially from the at least one processor after the second command is received from the at least one processor: display, via the display panel, the first image by scanning the first image received from the at least one processor, and perform storing of the first image in the memory of the display driver circuitry despite the second command; and in response to a second image received from the at least one processor while displaying the first image via the display panel: display, via the display panel, the second image by scanning the second image received from the at least one processor, and in accordance with the second command, refrain from storing of the second image in the memory of the display driver circuitry.
