Variable Refresh Rate Display System for Power Optimization

The display area is divided into multiple regions (first display area, second display area, and third display area) with different refresh frequencies. The first display area corresponding to the vision focus area uses a higher refresh frequency (first refresh frequency) to ensure display quality, while the second and third display areas use lower refresh frequencies (second and third refresh frequencies respectively) to reduce power consumption. This spatial segmentation allows the system to maintain high display quality where needed while minimizing energy consumption across the entire display.

Different regions of the display are assigned different refresh frequencies based on their importance to the user's visual experience. The vision focus area (first display area) receives higher refresh frequency for superior display quality, while peripheral areas (second and third display areas) use lower refresh frequencies. This local differentiation optimizes the balance between display quality and power consumption by applying high performance only where necessary.

The display panel is segmented into multiple areas with different refresh frequency requirements. By identifying the vision focus area and assigning it a higher refresh frequency while using lower refresh frequencies for other areas, the system achieves high display realism locally without the prohibitive power consumption of uniformly high refresh frequencies across the entire display.

The patent implements local quality by providing high refresh frequency (and thus high display realism) only in the vision focus area where the user's attention is concentrated, while using lower refresh frequencies in peripheral areas where display realism is less critical to the user experience, thereby optimizing power consumption.

The display driving device is segmented into multiple driving units, each responsible for driving a specific display area with its designated refresh frequency. This modular segmentation of the driving device allows for independent control of each region, managing the complexity through structured organization while enabling power consumption optimization through differential refresh frequencies.

The display driving device dynamically adjusts the refresh frequency of different display areas based on the vision focus area determination. This dynamic adaptation allows the system to optimize power consumption in real-time while managing complexity through flexible, condition-based control rather than static, fixed-frequency driving.

The system employs feedback mechanisms through eye-tracking devices or video image changing area detection devices that continuously monitor user gaze or image changes. This feedback information is used to dynamically determine and update the vision focus area, ensuring that high refresh frequency is applied to the correct region while managing complexity through automated, sensor-driven control.

The vision focus area determination device operates autonomously to identify and track the user's area of interest without requiring manual intervention. By self-determining the focus area through eye-tracking or image analysis, the system maintains display quality in the relevant region while reducing the complexity burden on the user and enabling automated optimization.
