Solution Overview
Problem
Current evaporation apparatuses for OLED manufacturing face inefficiencies in adjusting the thickness of functional layers, requiring time-consuming temperature changes and exposing electrical circuits to high temperatures, leading to damage and sticking issues.
Innovation Solution
An evaporation apparatus with an inner and outer plate configuration that allows for adjustable evaporation range by moving the outer plate, enabling quick adjustment of evaporation rate and thickness of film layers, while protecting electrical circuits from high temperatures and material sticking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If temperature is changed to adjust evaporation rate, then film layer thickness can be adjusted, but adjustment time increases significantly
Solution Approach 1:
The patent introduces a movable plate that can dynamically adjust the evaporation range by changing its position relative to the evaporation source. This dynamic mechanical adjustment allows rapid modification of the evaporation rate without requiring temperature changes, thereby resolving the contradiction between manufacturing precision (film thickness control) and loss of time (adjustment speed). The movable plate creates different evaporation ranges by varying its distance from the evaporation source, enabling quick switching between high and low evaporation rates.
2Ease of operation
If electrical circuits are exposed during evaporation process, then operation is simplified, but circuits suffer damage from high temperature and material sticking
Solution Approach 1:
The patent introduces a plate structure as an intermediary element between the evaporation source and the electrical circuits. This plate serves multiple functions: it shields the circuits from direct exposure to high temperatures and evaporated materials, preventing damage and sticking issues, while still allowing the system to operate effectively. The plate can be positioned to provide necessary shielding without completely blocking the evaporation process, thus maintaining reliability while preserving ease of operation.
