Engineering Contradiction Analysis
1Reliability
If a transmission area is provided in the component area for light transmission, then signal transmission capability is improved, but light diffraction occurs causing image quality degradation
Solution Approach 1:
The substrate is designed with different local structures: a first region with grooves to reduce diffraction and a second region without grooves to maintain signal transmission. This local differentiation allows each area to optimize its function - the grooved area minimizes optical interference while the non-grooved area ensures proper signal transmission through the transmission area.
2Object-affected harmful factors
If grooves are added to the substrate to reduce light diffraction, then image quality is improved, but device complexity increases
Solution Approach 1:
The substrate is segmented into distinct functional regions: a first region containing grooves for diffraction reduction and a second region without grooves for signal transmission. This segmentation allows the complex grooved structure to be localized only where needed for optical quality, while the rest of the substrate maintains a simpler structure optimized for electrical signal transmission.
