Curved Display Panel Cured Casing Structural Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional curve-shaped display modules experience structural instability and component wear due to interspaces and relative displacement between the display panel and curve-forming plates, leading to assembly control challenges and potential damage.
Innovation Solution
A manufacturing method and apparatus using a curve-forming mold, curable material dispensing device, and curing device to create a curve-shaped display module, where the display panel is pressed into a curved shape and coated with a curable material that forms a cured casing to maintain the curvature, enhancing structural stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If curve-forming plates are used to transform the planar display panel into a curve-shaped display panel, then the display panel can achieve curved shape, but interspaces exist between the display panel and the curve-forming plates causing change in curvature and structural instability
Solution Approach 1:
The patent uses a flexible display panel that can be bent into a curved shape without requiring rigid curve-forming plates. The display panel itself is designed with flexible substrate and encapsulation layers that maintain structural integrity while achieving the desired curvature, eliminating the interspaces and instability issues caused by separate curve-forming plates
Solution Approach 2:
The patent removes the curve-forming plates from the structure entirely, extracting the curve-forming function from separate components and integrating it directly into the display panel through flexible materials and manufacturing processes that enable the panel to maintain its curved shape inherently
2Shape
If curve-forming plates are used to confine the display panel, then the display panel can maintain curved shape, but relative displacement occurs between the display panel and curve-forming plates leading to damage or weariness of related components
Solution Approach 1:
The patent merges the display panel and curve-forming structure into a single integrated unit. The flexible display panel is manufactured to inherently maintain its curved shape through its substrate and encapsulation structure, eliminating the need for separate curve-forming plates and thus preventing relative displacement and component wear
Solution Approach 2:
The patent applies preliminary curvature to the display panel during the manufacturing process, forming the curved shape before final assembly. The flexible substrate and encapsulation layers are pre-formed with the desired curvature, ensuring the display panel maintains its shape without requiring additional curve-forming plates that could cause displacement
3Shape
If traditional curve-forming plates with sealants are used, then the display panel can be transformed into curved shape, but it is difficult to control the assembly yield of the display panel and curve-forming plates during assembly
Solution Approach 1:
The patent extracts the curve-forming function from separate plates and sealants, integrating it directly into the display panel manufacturing process. The flexible display panel is formed with its curved shape and encapsulation in a single integrated manufacturing process, eliminating the need for separate assembly steps and improving assembly yield control
Solution Approach 2:
The patent performs preliminary formation of the curved shape and encapsulation during the display panel manufacturing process itself, before final assembly. The flexible substrate and encapsulation layers are pre-formed with precise curvature control, eliminating the need for subsequent assembly operations with curve-forming plates and sealants
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method ensures better structural stability and control over the assembly process, preventing damage and weariness of components by forming a tight, adhesion-based cured casing that sustains the curved shape of the display panel.
Implementation Method 1
The curable material is then cured to form a first cured casing by using the curing device
Implementation Method 2
The first cured casing covers the first curved surface and closely attached to the first curved surface with an adhesion force therebetween to sustain the curved shape of the display panel
