Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same surface serves as both light-receiving and light-emitting surface, then device integration is improved, but adaptability to different apparatus types deteriorates
Solution Approach 1:
The device is divided into separate functional regions: a light-receiving surface with photodiodes for capturing images and a light-emitting surface with EL elements for displaying images. This segmentation allows the same device structure to be adapted to different apparatus types (smartphones, HMDs, smart glasses) by configuring different components in each region, thereby improving versatility while maintaining integration.
2Speed
If image processing time is reduced, then user tracking capability is improved, but signal transmission path length must be minimized
Solution Approach 1:
The signal transmission paths are configured to lie within the pixel region, merging the photoelectric conversion elements, signal processing circuits, and light-emitting elements into a highly integrated structure. This minimizes the signal transmission path length and reduces image processing time, enabling fast tracking of moving objects while maintaining a compact device design.
3Loss of time
If photoelectric conversion and light emission are integrated in the same pixel region, then processing time is reduced, but manufacturing precision requirements increase
Solution Approach 1:
Different regions within the pixel structure are assigned specific functions with optimized characteristics: photodiodes are positioned to maximize light reception area, signal processing circuits are placed to minimize transmission distance, and EL elements are arranged for efficient light emission. This local optimization of element positions and configurations reduces processing time while maintaining manufacturability through standardized fabrication processes.
