Curved Side Surfaces Enhance Shock Resistance in Display Substrates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses, such as organic light-emitting and liquid crystal displays, are prone to damage from external shocks due to their thin and flexible structures, which lack sufficient shock resistance.
Innovation Solution
A method of manufacturing a display apparatus involves preparing a first substrate with a display, adhering a second substrate using a sealing element, and employing a blocking member with blocking patterns to control the exposure of the sealing element during cutting, resulting in curved side surfaces that enhance shock resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If display apparatuses are made thin and flexible, then they can be manufactured as thin and flexible display apparatuses, but they become easily damaged by external shocks
Solution Approach 1:
The patent applies curvature to the side surfaces of the display apparatus by controlling the exposure of the sealing element during manufacturing. The blocking member with blocking patterns prevents exposure of specific portions of the sealing element, causing the side surfaces to curve inward. This curved geometry distributes stress more effectively during external shocks, improving shock resistance while maintaining thin and flexible characteristics.
2Ease of manufacture
If the sealing element is fully exposed during manufacturing, then the cutting process is simplified, but the side surfaces become flat and vulnerable to shock damage
Solution Approach 1:
The patent applies local quality by using blocking patterns on the blocking member that selectively prevent exposure of specific portions of the sealing element. The blocking patterns are arranged to create localized curved regions on the side surfaces while leaving other areas flat, optimizing both manufacturing feasibility and shock resistance in different regions of the display apparatus.
3Shape
If blocking patterns are placed close together, then the curved side surfaces are more effectively formed, but the blocking member becomes more complex
Solution Approach 1:
The patent applies partial action by using blocking patterns that cover only the critical portions of the sealing element that need protection. The blocking patterns are strategically positioned to create sufficient curvature for shock resistance without requiring complete coverage, thereby simplifying the blocking member structure while achieving the desired curved side surfaces.
