Samsung patents display tech that adjusts refresh based on processor load

This filing describes a method where a device's processor checks its own workload to determine how often to update the screen. If the processor is busy but the device is cool, it shortens the time between checks to adjust the display's refresh rate more frequently.

Why it mattersThis is a routine optimization that helps balance screen smoothness with processor efficiency, though it is a technical detail most users will never see.

In the filing’s own words

Provided is an electronic device comprising a touch-sensitive display, a processor operatively connected to the display and a memory operatively connected to the processor. The memory stores instructions which, when executed, cause the electronic device to display visual information on the display and measure, based on a second measurement period, a utilization rate of the processor, while the visual information is being displayed on the display and the utilization rate of the processor is being measured based on the second measurement period, identify that a particular event related to performance of the processor has occurred, and based on identifying that the particular event has occurred, change a measurement period for measuring the utilization rate of the processor to a first measurement period shorter than the second measurement period.

What exactly they claim (claim 1)

1. An electronic device comprising: a touch-sensitive display; a processor operatively connected to the display; and memory operatively connected to the processor, wherein the memory stores instructions which, when executed by the processor, cause the electronic device to: display visual information on the display and measure, based on a second measurement period, a utilization rate of the processor, while visual information is being displayed on the display and the utilization rate of the processor is being measured based on the second measurement period, identify that a particular event related to performance of the processor has occurred, and based on identifying that the particular event has occurred and a determination that an internal temperature is lower than a designated temperature value, change a measurement period for measuring the utilization rate of the processor to a first measurement period shorter than the second measurement period.
