Samsung patents chip that saves power by stepping down display data speed
Samsung describes an application processor that manages how it sends screen data to a display. It automatically switches between different levels of power saving, such as sleep or full off, depending on how often the screen needs to update.
In the filing’s own words
An application processor is provided. The application processor includes: an interface configured to transmit frame data to an external device; control logic configured to determine whether to enter a low power mode based on whether data transmission is present; and a low power controller configured to cause the application processor to enter one of a plurality of low power modes in a stepwise manner during a period in which no data transmission occurs. The plurality of low power modes include at least a phase locked loop (PLL) sleep mode, an ultra low power state (ULPS) mode, and a power-off mode. The low power controller is further configured to selectively apply one of the plurality of low power modes based on a frame update interval.
What exactly they claim (claim 1)
1. An application processor, comprising: an interface configured to transmit frame data to an external device; control logic configured to determine whether to enter a low power mode based on whether data transmission is present; and a low power controller configured to cause the application processor to enter one of a plurality of low power modes in a stepwise manner during a period in which no data transmission occurs, wherein the plurality of low power modes include at least a phase locked loop (PLL) sleep mode, an ultra low power state (ULPS) mode, and a power-off mode, and wherein the low power controller is further configured to selectively apply one of the plurality of low power modes based on a frame update interval.
