Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If afterimage compensation and optical compensation are performed separately using separate memory devices, then each compensation function can be independently implemented, but memory device usage efficiency deteriorates and device complexity increases
Solution Approach 1:
The patent combines afterimage compensation data and optical compensation data into a single unified memory device. The compensation data storage unit stores both types of compensation data together, eliminating the need for separate memory devices while maintaining all compensation functions. This merging approach reduces device complexity and improves memory usage efficiency.
Solution Approach 2:
The unified memory device is designed to serve multiple compensation functions simultaneously. By storing both afterimage compensation data and optical compensation data in the same memory device, the system achieves multi-functionality, allowing a single memory device to handle multiple compensation tasks that previously required separate dedicated memory devices.
2Ease of manufacture
If separate memory devices are used for afterimage compensation data and optical compensation data, then data organization is simplified, but memory device usage efficiency deteriorates
Solution Approach 1:
The patent merges the storage of afterimage compensation data and optical compensation data into a single memory device with a unified compensation data storage unit. This combining approach improves memory device usage efficiency by utilizing available memory resources more effectively, while the internal data structure maintains clear organization of different compensation data types.
