Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an opening area is introduced in the display device to add functions, then the versatility and functionality of the device are improved, but the structural integrity and manufacturing complexity in the surrounding area deteriorate
Solution Approach 1:
The metal layer is divided into multiple separate regions (first region, second region, third region) that are spaced apart from each other, with each region serving specific functions around the opening area. This segmentation allows independent optimization of each region while maintaining overall structural integrity.
Solution Approach 2:
The metal layer regions are arranged in a nested configuration around the opening area, with protrusions and recesses that interlock like nested dolls. The first region has a protrusion that extends toward the second region, which has a corresponding recess to receive it, creating a compact integrated structure.
2Adaptability or versatility
If metal layer regions are spaced apart to accommodate the opening area, then the integration of additional components is improved, but the structural support and electrical connectivity deteriorate
Solution Approach 1:
The metal layer regions are arranged asymmetrically around the opening area, with the first region positioned at a first position, the second region at a second position, and the third region at a third position. Each region has asymmetric protrusions and recesses that interlock to provide structural support while accommodating the opening.
Solution Approach 2:
The metal layer regions extend in multiple dimensions around the opening area, with protrusions extending in radial directions and recesses positioned to receive them. This multi-dimensional arrangement provides structural support through spatial distribution rather than simple linear connection.
3Measurement precision
If sensing electrodes are arranged alternately to improve input sensing accuracy, then the measurement precision is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The first sensing electrodes and second sensing electrodes are merged into a single input sensing layer, arranged alternately in an interdigitated pattern. This merging approach achieves high measurement precision through the alternating arrangement while simplifying manufacturing by using a single layer structure rather than multiple stacked layers.
Solution Approach 2:
The sensing electrodes are arranged in curved or circular patterns around the opening area, with the first sensing electrodes and second sensing electrodes alternating in a radial configuration. This curved arrangement improves sensing accuracy by distributing electrodes evenly around the opening while maintaining manufacturing simplicity through rotational symmetry.

AI summary
A display device includes a substrate including an opening area and a display area at least partially surrounding the opening area; and a metal layer including a first region and a second region adjacent to a non-display area between the opening area and the display area, the first region and the second region are spaced apart from each other, and one of the first region and the second region includes a protrusion extending toward the other of the first region and the second region, and the other of the first region and the second region has a shape to receive the protrusion.
