Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sequential reading of pixel signals is used, then device complexity is reduced, but productivity deteriorates due to slow data delivery
Solution Approach 1:
The patent replaces the traditional sequential electronic reading mechanism with an optical parallel reading system. Light from the display matrix directly illuminates the photodetector array, enabling simultaneous detection of all pixel signals through optical paths rather than sequential electronic scanning, thus achieving parallel signal acquisition without complex electronic multiplexing circuits
Solution Approach 2:
The display matrix serves dual functions: as the light source for visual output and as the object to be measured by the photodetector array. This self-measuring capability eliminates the need for separate measurement devices and enables parallel reading of all pixel intensities simultaneously through the optical system
2Measurement precision
If separate measurement steps are used for brightness adjustment, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent merges the display function and the measurement function into a single integrated system. The photodetector array continuously monitors the actual brightness of the display matrix in real-time, allowing immediate feedback and adjustment without separate measurement steps, thus achieving both precision and speed
Solution Approach 2:
The system implements real-time feedback by having the photodetector array continuously measure the actual brightness output of the display matrix. This measured information is immediately used to adjust the driving signals, creating a closed-loop control system that achieves precise brightness adjustment without time loss
