Rollable Flexible Display Power Control to Prevent Peak Load Shutdown

The patent applies dynamics by making the motor speed variable rather than fixed. The processor dynamically adjusts the motor's rotational speed based on real-time power availability from the battery. When power is sufficient, the motor operates at higher speeds for smooth display movement; when power is limited, the speed is reduced to prevent power-off, thus resolving the contradiction between movement performance and power supply stability.

The patent changes the operational parameters of the motor based on battery power status. The processor monitors battery output capacity and adjusts motor control parameters (such as duty cycle in PWM control) to match available power. This parameter adaptation allows the system to operate reliably across varying power conditions while maintaining optimal display control when possible.

The patent applies partial action by providing more than enough power only when needed for motor operation, rather than continuously. The battery is sized for portability (not excessive capacity), but the system temporarily draws peak power from the battery during motor activation. The processor manages this partial/excessive power delivery by controlling motor operation timing and duration, allowing a smaller battery to suffice while still meeting peak power demands.

The patent uses periodic action in the sense of intermittent high-power bursts for motor operation rather than continuous high power. The motor operates in periodic cycles (starting, moving, stopping) with low or zero power consumption during idle periods. This allows the battery to be sized for average power needs plus some peak capacity, rather than continuous peak power, reducing overall battery size and device weight.

The patent makes motor power consumption dynamic rather than static at full power. The processor continuously monitors battery status and adjusts motor power delivery in real-time. When battery power is sufficient, the motor receives full power for responsive operation; when power is limited, the processor reduces motor power to prevent power-off. This dynamic power management maintains responsiveness when possible while preventing excessive power consumption.

The patent implements feedback control where the processor monitors battery power availability and uses this feedback to adjust motor control signals. The system creates a closed-loop control where power consumption is continuously adapted based on battery status feedback, ensuring the motor operates within available power limits while maintaining optimal performance when power is sufficient.
