Display Panel Partition Groove Eliminates Flattening Step
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing process of display panels is complex and time-consuming, particularly due to the need for additional steps to flatten steps and manage the integration of functional modules, which increases costs and reduces efficiency.
Innovation Solution
A display panel design that includes a substrate with distinct areas and a partition featuring a groove on its upper surface, allowing for the simplification of the manufacturing process by omitting the need for an additional flattening step, and a method of manufacturing that forms a groove on the upper surface of the organic layer between the hole area and the display area, reducing the complexity and time required for production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If additional flattening steps are performed to manage step integration, then manufacturing precision is improved, but manufacturing complexity and time increase
Solution Approach 1:
The groove is formed on the upper surface of the organic layer during the partition formation process, before the encapsulation process begins. This preliminary action eliminates the need for subsequent flattening steps, as the groove structure inherently manages the step difference between the hole area and display area.
Solution Approach 2:
The partition is divided into multiple layers (first layer, second layer, third layer) with the groove formed on the upper surface of the organic layer. This segmentation allows each layer to serve specific functions while the groove structure manages step integration without requiring additional flattening processes.
2Manufacturing precision
If additional flattening steps are performed, then manufacturing precision is improved, but manufacturing time increases
Solution Approach 1:
The groove is formed during the partition formation process, performing the step management action in advance. This eliminates the need for separate flattening steps that would consume additional manufacturing time, while still achieving the required precision for encapsulation.
3Manufacturing precision
If additional flattening steps are performed, then manufacturing precision is improved, but manufacturing cost increases
Solution Approach 1:
The groove structure is formed during the partition formation process, eliminating the need for subsequent flattening steps. This reduces manufacturing cost by removing unnecessary process steps while maintaining the precision required for successful encapsulation and functional module integration.
4Area of stationary object
If functional modules are integrated under the display area, then display area is enlarged, but manufacturing complexity increases
Solution Approach 1:
The partition is segmented into multiple layers with the groove formed on the organic layer, allowing the functional module to be integrated under the display area without requiring additional flattening processes. This segmentation simplifies the overall manufacturing process while enabling functional module integration.
Solution Approach 2:
The groove is formed in advance during partition formation, preparing the structure for functional module integration under the display area. This preliminary action eliminates subsequent flattening steps, reducing manufacturing complexity while enabling enlarged display area through functional module integration.
