Engineering Contradiction Analysis
1Use of energy by moving object
If transparent display chips are optimized for low-power applications, then power consumption is reduced, but display performance and light transmission are compromised
Solution Approach 1:
The display chip is divided into multiple zones with different transparency characteristics. Some zones have higher transparency for better light transmission and display performance, while other zones have lower transparency optimized for low-power operation. This segmentation allows the system to achieve both low-power consumption and adequate display performance simultaneously by allocating different functional requirements to different spatial regions.
Solution Approach 2:
Different regions of the display chip are assigned different optical properties and performance characteristics. The patent implements zones with varying transparency levels, pixel densities, and light transmission properties tailored to specific functional requirements. This local quality approach enables critical display areas to maintain high performance while non-critical areas operate in low-power mode.

3Adaptability or versatility
If a single display configuration is used, then device simplicity is maintained, but adaptability to different applications is limited

The multi-zone display chip is designed to serve multiple applications and functions within a single device. By incorporating zones with different transparency and performance characteristics, the display can adapt to various operational modes including low-power navigation, high-performance display, and mixed-mode operation, thereby achieving universality across different use cases without requiring multiple separate devices.
