A recently granted patent (Publication Number: US11887520B2) discloses a chipset for frame rate control (FRC) that includes two FRC chips working in tandem to enhance image quality on display panels. The first FRC chip processes a portion of input image data through motion compensation to generate a corresponding output image data with a higher frame rate than the input. Simultaneously, the second FRC chip handles another portion of the input data, which is then combined with the output from the first chip to create a complete image for display. This innovative approach allows for smoother motion rendering and improved visual performance on electronic devices utilizing this chipset.

Furthermore, the patent details the intricate workings of the FRC chipset, including the division of input data, motion estimation, and compensation processes between the two chips. By splitting the workload and optimizing the motion processing for different parts of the image data, the chipset achieves a seamless integration of frames and interpolated frames, resulting in a cohesive output for display panels. The method outlined in the patent ensures that each frame's pixel values are fully utilized, with overlapping sections to maintain image integrity. Overall, this chipset promises to enhance the viewing experience on electronic devices by providing a sophisticated frame rate control mechanism that optimizes image quality and motion rendering for display panels in various applications.
