Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transmission area is added to the display device to enable additional functions, then the versatility and functionality of the device are improved, but the reliability and structural strength around the transmission area deteriorate due to vulnerability to external light and static electricity
Solution Approach 1:
The metal layer is segmented into multiple parts: a first metal layer portion surrounding the transmission area, a second metal layer portion between pixels, and a third metal layer portion connecting them. This segmentation allows each portion to perform specific protective functions while maintaining overall structural integrity around the vulnerable transmission area
Solution Approach 2:
The protective structure is extended from a two-dimensional plane to three-dimensional space by forming the metal layer at multiple stacked levels (first, second, and third metal layer portions). This multi-level arrangement provides comprehensive protection around the transmission area from different spatial dimensions, blocking external light and static electricity more effectively
2Object-affected harmful factors
If the metal layer completely surrounds the transmission area to block external light and static electricity, then the protection against harmful factors is improved, but the manufacturing complexity increases due to the need for precise hole positioning and multiple layer alignment
Solution Approach 1:
Holes are locally positioned in the metal layer at specific locations corresponding to the transmission area and pixel regions. This local quality approach allows the metal layer to provide comprehensive protection while maintaining manufacturing feasibility through precise but localized hole formation rather than requiring complex patterns throughout the entire structure
Solution Approach 2:
The metal layer structure is nested across multiple stacked levels, with the first, second, and third metal layer portions arranged vertically to form a multi-level protective enclosure around the transmission area. This nesting approach creates comprehensive protection while utilizing vertical space efficiently, reducing the horizontal footprint and simplifying manufacturing

AI summary
A display device includes a display panel comprising two pixels spaced apart from each other and a transmission area between the two pixels. An input sensing section is disposed on the display panel and comprises sensing electrodes and trace lines electrically connected to the sensing electrodes. A metal layer is on the display panel. The metal layer is disposed between the two pixels and surrounds the transmission area. The metal layer comprises a first hole located in the transmission area. The first hole has a first width. An optical functional section is on the metal layer. The optical functional section includes a second hole that overlaps the first hole. The second hole has a second width that is greater than the first width.
