LCD Support Structures Preventing Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Liquid Crystal Displays (LCDs), support spacers can detach and cause misalignment when subjected to external forces, leading to image quality issues like light leakage and uneven display due to their inability to recover from displacement.
Innovation Solution
A display panel design featuring a color film substrate with support structures composed of stacked layers, where a flat layer with a greater slope angle covers remaining support layers, providing gentle protrusions that maintain alignment and prevent detachment during external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional support spacers are used in LCDs, then the structure is simple and easy to manufacture, but the spacers can detach and cause misalignment when subjected to external forces
Solution Approach 1:
The support structure is divided into multiple support layers stacked together, with each layer providing structural support. This segmentation allows the support function to be distributed across multiple simpler components rather than requiring a single complex spacer structure.
Solution Approach 2:
The support layers are nested within each other in a stacked configuration, with each layer positioned inside or adjacent to the previous layer. This nesting arrangement creates a compact, stable support structure that resists detachment while maintaining manufacturing simplicity.
2Reliability
If support spacers are used to ensure uniform liquid crystal thickness, then display uniformity is improved, but the spacers cannot recover from displacement when detached
Solution Approach 1:
The support layers are designed with flexible connections that allow dynamic adjustment. When external forces cause displacement, the layers can flex and return to their original positions, providing self-recovery capability while maintaining display uniformity.
Solution Approach 2:
The support layers are constructed using flexible materials that can bend and deform elastically. This flexibility enables the support structure to absorb external forces and recover its original configuration, preventing permanent misalignment and maintaining display quality.
3Reliability
If a flat layer with greater slope angle is added to support structures, then detachment is prevented and alignment is maintained, but the manufacturing process becomes more complex
Solution Approach 1:
The flat layer is applied selectively to specific regions of the support structure where detachment is most likely to occur. By concentrating the anti-detachment function in localized areas with specific slope angles, the overall manufacturing process remains relatively simple while achieving the desired reliability.
Solution Approach 2:
The flat layer with the greater slope angle is pre-formed and positioned on the support layers before final assembly. This preliminary action ensures that the anti-detachment geometry is already in place, simplifying the final manufacturing steps while maintaining alignment reliability.
