Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional peeling method is used to separate the flexible display panel from the rigid substrate, then the peeling process can be completed, but damage occurs to the flexible display panel due to misalignment and tension issues
Solution Approach 1:
A peeling plate is introduced as an intermediary tool between the flexible display panel and the substrate. The peeling plate includes adsorption units that vacuum-adhere to the panel surface and a convex bottom surface that contacts the panel to apply controlled peeling force, preventing direct damage from conventional peeling methods
Solution Approach 2:
Adsorption units with vacuum holes are used to create vacuum pressure that adheres the peeling plate to the flexible display panel. This pneumatic mechanism ensures stable attachment and controlled peeling without causing panel damage through excessive tension or misalignment
2Ease of manufacture
If the flexible display panel is attached to a rigid substrate for manufacturing, then manufacturing processes can be performed, but misalignment and tension issues occur during the peeling process
Solution Approach 1:
The peeling plate features a convex bottom surface that contacts the flexible display panel. This curved geometry allows the peeling force to be distributed evenly across the panel surface, preventing misalignment and maintaining manufacturing precision during the separation process
3Stability of the object's composition
If vacuum adsorption is applied to hold the flexible display panel, then panel stability is improved, but the complexity of the peeling apparatus increases
Solution Approach 1:
The adsorption system is segmented into multiple discrete adsorption units distributed across the peeling plate. Each unit has vacuum holes that can be independently controlled, providing stable panel holding while keeping the overall system modular and manageable rather than overly complex

AI summary
A flexible display panel peeling apparatus for peeling a flexible display panel attached to a top surface of a substrate includes a stage fixed to the substrate and a peeling plate comprising a bottom surface that is convex toward the flexible display panel and a plurality of adsorption units defined in the bottom surface to adsorb the flexible display panel to the bottom surface. Since the flexible display panel is successively peeled through the peeling plate, the flexible display panel may be peeled from the substrate without being damaged.
