Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fluid dispensing process is used to form organic films, then material can be discharged to particular locations, but alignment defects occur due to process errors limiting display resolution
Solution Approach 1:
The patent replaces the mechanical fluid dispensing process with a photo-polymerization process. A photoresist composition is coated uniformly across the substrate, then exposed through a mask pattern to define precise locations. The exposed regions undergo photo-polymerization to form organic films with high precision, eliminating alignment defects associated with mechanical dispensing while achieving high display resolution.
2Ease of manufacture
If fluid dispensing process is used, then organic film can be formed at specific locations, but process complexity increases due to difficulty in precise discharging
Solution Approach 1:
The patent applies preliminary action by first coating a uniform photoresist composition across the entire substrate before exposure. This preliminary coating step simplifies the overall process by eliminating the need for complex precise dispensing operations during fabrication. The pattern definition is then achieved through simple mask exposure and photo-polymerization, significantly reducing process complexity while maintaining ease of manufacture.
