Abstract
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for DDIC fallback scaling for a partial frame update. A processor may detect that a partial frame update is to occur with respect to a frame, where the frame is at a first resolution. The processor may determine, based on the detection that the partial frame update is to occur, to switch a scaling for the frame from a display processor to a DDIC. The processor may output, for the DDIC and based on the detection that the partial frame update is to occur, an indication that the DDIC is to scale the frame to a second resolution.
Claims21
An apparatus for display processing, comprising:
- a memory;
- and
- at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
- detect that a partial frame update is to occur with respect to a frame, wherein the frame is at a first resolution;
- determine, based on the detection that the partial frame update is to occur, to switch a scaling for the frame from a display processor to a display driver integrated circuit (DDIC);
- and
- output, for the DDIC and based on the determination to switch the scaling for the frame from the display processor to the DDIC, an indication that the DDIC is to scale the frame to a second resolution.
An apparatus for display processing, comprising:
- a memory;
- and
- at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
- obtain a first indication that scaling for a frame is to be switched to a display driver integrated circuit (DDIC), wherein a partial frame update is associated with the first frame, and wherein the scaling for the frame is performed at a display processor prior to the obtainment of the first indication;
- obtain a second indication that the DDIC is to scale the frame;
- obtain the frame at a first resolution;
- and
- scale the frame from the first resolution to a second resolution based on the first indication and the second indication.
