Display Refresh Switching With Early Frame Generation

The patent applies preliminary action by determining whether to generate an image frame in advance based on the display completion status before the synchronization signal edge arrives. The processor proactively checks if the previous frame is completed and generates the next frame earlier when appropriate, rather than passively waiting for the Vsync edge, thus preventing frame loss while maintaining synchronization

The patent implements dynamics by making the frame generation timing flexible rather than fixed. The system dynamically adjusts whether to generate a frame at the Vsync edge or in advance based on real-time conditions (whether the previous frame is completed), allowing the timing strategy to adapt to different refresh rate scenarios and prevent frame loss during transitions

During refresh rate switching, the processor performs preliminary checks to determine if image frames should be generated in advance. When switching from high to low refresh rate, the system proactively generates frames based on display completion status before the extended Vsync period elapses, compensating for the increased time consumption of the second signal and preventing frame loss

The patent applies parameter changes by dynamically adjusting the frame generation timing parameter based on refresh rate conditions. When the refresh rate changes, the system modifies whether to generate frames at the Vsync edge or in advance, optimizing the timing parameter to match the new refresh rate and prevent frame loss during the transition
