Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components like cameras are integrated within the display area, then functionality is enhanced, but transmittance and image quality may be compromised
Solution Approach 1:
The display area is segmented into a component area (where the camera is located) and a main area. The data connection line is routed to overlap with the component area rather than the main area, segmenting the impact zone and preserving transmittance in the main display region while still enabling component integration.
Solution Approach 2:
The patent applies local quality by creating a component area with different optical properties (lower transmittance) compared to the main area (higher transmittance). The data connection line is specifically positioned to overlap the component area, allowing the system to have varying local characteristics - the component area can support component integration with reduced transmittance requirements, while the main area maintains high transmittance for optimal display quality.
2Adaptability or versatility
If data connection lines are routed through the component area, then component integration is enabled, but display area utilization is reduced
Solution Approach 1:
The display area is divided into a component area and a main area. The data connection line is routed through the component area, segmenting the impact so that the main area remains fully available for display purposes. This segmentation allows the component area to serve dual purposes: housing components and accommodating data connection lines.
Solution Approach 2:
The patent utilizes the spatial dimension by vertically positioning the data connection line between the substrate and the semiconductor layer, allowing it to pass through the component area without occupying horizontal display space. This dimensional approach enables the data connection line to coexist with the camera component in the same vertical stack without reducing the horizontal display area.
