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.
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.
2 . The electronic device of claim 1 , wherein the display driver circuitry is configured to:
before the second command is received from the at least one processor, receive, from the at least one processor, a third image;
in response to receiving the third image:
display, via the display panel, the third image by scanning the third image received from the at least one processor, and
based on the first command received from the at least one processor before the third image is received from the at least one processor, perform storing of the third image in the memory of the display driver circuitry;
while the third image is displayed in accordance with the scanning of the third image received from the at least one processor, display again, via the display panel, the third image by scanning the third image stored in the memory of the display driver circuitry;
while displaying of the third image is maintained in accordance with the scanning of the third image stored in the memory of the display driver circuitry, receive, from the at least one processor, the second command; and
in response to the 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
based on a time length in which displaying of the third image is maintained in accordance with the scanning of the third image received from the at least one processor and the scanning of the third image stored in the memory of the display driver circuitry, perform the storing of the first image in the memory of the display driver circuitry despite the second command.
3 . The electronic device of claim 2 , wherein the display driver circuitry is configured to:
in response to the first image received initially from the at least one processor after the second command is received from the at least one processor:
based on the time length being identified by the display driver circuitry as longer than a threshold time length, perform the storing of the first image in the memory of the display driver circuitry despite the second command, and
based on the time length being identified by the display driver circuitry as shorter than the threshold time length, refrain from storing the first image in the memory of the display driver circuitry in accordance with the second command.
4 . The electronic device of claim 2 , wherein the display driver circuitry is configured to:
based on a refresh rate for displaying the third image, identify the time length.
5 . The electronic device of claim 1 , wherein the display driver circuitry is configured to:
before the second image is received, display again, via the display panel, the first image by scanning the first image stored in the memory of the display driver circuitry despite the second command.
6 . The electronic device of claim 5 , wherein the display driver circuitry is configured to:
in response to the displaying of the first image by the scanning of the first image received from the at least one processor, perform the displaying of the first image by scanning the first image stored in the memory of the display driver circuitry despite the second command.
7 . The electronic device of claim 1 , wherein the second command is received from the at least one processor in a vertical front porch portion of a vertical synchronization signal used for displaying the first image.
8 . 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, wherein the first command is, until a third command is received from the at least one processor, for activating storing of an image received from the at least one processor in the memory of the display driver circuitry, wherein the second command is for activating only storing of an image initially received from the at least one processor in the memory of the display driver circuitry after the second command is transmitted from the at least one processor to the display driver circuitry, and wherein the third command is 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
based on the second command, perform storing of the first image in the memory of the display driver circuitry; 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
based on the second command, refrain from storing of the second image in the memory of the display driver circuitry.
9 . The electronic device of claim 8 , wherein storing of an image activated in accordance with the first command is deactivated based on receiving the second command.
10 . The electronic device of claim 8 , wherein storing of an image deactivated in accordance with the third command is activated based on receiving the first or second command.
11 . The electronic device of claim 8 , wherein storing of an image received from the at least one processor is deactivated unless the first or second commands are additionally received from the at least one processor after an image is stored in the memory of the display driver circuitry in accordance with the second command.
