Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cell areas are separated early in the manufacturing process, then productivity is improved, but static electricity damage occurs and reliability deteriorates
Solution Approach 1:
The patent applies preliminary action by placing an insulating layer on the light emitting element before separating the cell areas. This preparatory step ensures that static electricity is prevented from accumulating during the subsequent separation process, allowing early separation to occur without causing structural damage to the light emitting elements.
2Productivity
If cell areas are separated early, then productivity is improved, but light emission efficiency deteriorates due to static electricity
Solution Approach 1:
The insulating layer is applied before cell separation to prevent static electricity generation. This preliminary protective measure ensures that when cells are separated early for improved productivity, the light emitting elements remain free from static electricity damage, thereby maintaining their light emission efficiency.
3Reliability
If insulating layer is placed before cell separation, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the insulating layer formation process with the existing light emitting element placement process. By integrating the insulating layer application into the existing manufacturing flow before cell separation, the solution improves reliability without requiring a completely separate manufacturing stage, thereby limiting the increase in device complexity.

AI summary
A method for manufacturing a display device is provided. The method includes: placing a light emitting element on a substrate including cell areas; placing an insulating layer on the light emitting element; and separating the cell areas from each other. Light emitting panels are located on the substrate, correspond to each of the cell areas, and include the light emitting element. The separating of the cell areas from each other includes electrically separating the light emitting panels from each other. The electrically separating the light emitting panels from each other is performed after the placing of the insulating layer.
