Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motion interpolation technique is used to prevent motion blurring, then motion picture quality is improved, but additional memory is required to store motion data of entire pixel area
Solution Approach 1:
The display device is divided into multiple display areas, each with its own frame rate controller. Motion data is processed and stored locally for each segment rather than requiring centralized storage for the entire pixel area, eliminating the need for additional memory while maintaining motion interpolation capability.
Solution Approach 2:
The patent introduces a spatial dimension by dividing the display into multiple areas and enabling cross-area data sharing. Frame rate controllers can access motion data from neighboring areas through data communication lines, transforming the memory problem from a vertical storage issue into a horizontal data exchange problem that doesn't require additional memory capacity.
2Reliability
If frame rate control technique is applied to generate new image frames, then motion blurring is prevented, but processing time increases for fast speed motion
Solution Approach 1:
Motion data is pre-calculated and stored in the frame data buffer during the previous frame's processing. When generating new image frames for fast motion, the system can directly retrieve pre-computed motion vectors and interpolated data, significantly reducing real-time processing time while maintaining motion blurring prevention.
Solution Approach 2:
A frame data buffer acts as an intermediary between the input signal and frame rate controllers. This buffer pre-processes and stores motion data, allowing frame rate controllers to quickly access ready-made motion information without performing complex calculations in real-time, thus reducing processing time for fast motion sequences.
3Productivity
If additional memory is provided for motion data storage, then fast motion picture processing is enabled, but device complexity increases
Solution Approach 1:
The frame data buffer serves multiple functions: it stores image data, stores motion data, and acts as a communication interface between display areas. By making this single component multi-functional, the system achieves fast motion picture processing without adding dedicated memory structures, thereby avoiding increased device complexity.
Solution Approach 2:
The patent merges the functions of image data storage, motion data storage, and data communication into a unified frame data buffer structure. This consolidation eliminates the need for separate additional memory components while enabling fast motion processing through efficient data access and sharing across display areas.
Data Source
AI summary
A display device includes a data request unit in a frame rate controller, and requires and transmits necessary data for the frame data buffer receiving and storing the image data of an entire pixel area and the rest of the frame rate controllers. In a case of a motion picture that is moved among a plurality of display areas, the image data corresponding to a plurality of regions is transmitted from the frame data buffer or a plurality of frame rate controllers, and in a case of the motion picture that is moved between neighboring pixel areas, the image data of the neighboring pixel area is transmitted from the frame data buffer or the neighboring frame rate controller for processing. Accordingly, a fast-moving motion picture may be realized without the need for an additional memory.
