Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If liquid crystal lenses are used to switch between 2D and 3D modes, then the display mode switching capability is improved, but the optical path changes and image quality degradation occur
Solution Approach 1:
The display panel is divided into a lens area with liquid crystal lenses and a peripheral area with bus line layers. This segmentation allows the liquid crystal lenses to be positioned precisely without bus lines interfering with their optical paths, thereby maintaining image quality while enabling 2D-3D mode switching capability
Solution Approach 2:
The bus line layers are arranged in the peripheral area surrounding the lens area, utilizing the spatial dimension around the optical path. This dimensional arrangement separates the electrical connection function from the optical function, preventing bus lines from blocking light and causing optical path changes that would degrade image quality
2Ease of manufacture
If bus lines are placed in the lens area to connect electrodes, then the electrical connection is improved, but the optical path is blocked and image quality deteriorates
Solution Approach 1:
The bus lines are extracted from the lens area and relocated to the peripheral area. This extraction removes the obstructing element (bus lines) from the optical path while preserving the electrical connection function through extensions that reach from the peripheral bus lines to the liquid crystal lenses, thereby improving light transmission without sacrificing ease of manufacture
3Productivity
If the interval between bus lines is reduced to increase electrode connections, then the number of connected electrodes is improved, but the manufacturing precision requirements increase
Solution Approach 1:
Multiple bus line layers are stacked in the vertical dimension within the peripheral area, allowing numerous electrodes to be connected without reducing the horizontal interval between bus lines. This multi-layer arrangement increases the number of connected electrodes while maintaining relaxed manufacturing precision requirements, as each layer can be manufactured with standard spacing
