Deformable Capsule Buffer for Liquid Crystal Display Light Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buffer structures in liquid crystal display devices, such as solid silica gel strips, fail to effectively mitigate uneven internal forces caused by deformation of the liquid crystal panel or backboard, leading to visible light leakage due to their limited buffer capabilities.
Innovation Solution
A deformable sealed capsule with a flowable filler, such as an inert gas or liquid, is used between the liquid crystal panel and the backboard, allowing the filler to redistribute forces within the capsule to achieve balance and reduce light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a solid silica gel strip is used as a buffer, then the buffer function is provided, but the uneven internal forces caused by deformation cannot be effectively mitigated
Solution Approach 1:
The patent changes the physical state of the buffer material from solid to fluid (gas or liquid). This parameter change allows the buffer to transform from a rigid structure that cannot adapt to deformation into a fluid that can flow and redistribute forces dynamically, thereby resolving the contradiction between providing buffer function and mitigating uneven internal forces
Solution Approach 2:
The patent introduces a dynamic element by using a fluid-filled capsule instead of a static solid gel strip. The fluid can move and redistribute within the capsule in response to applied forces, creating a dynamic buffer system that adapts to deformation and effectively balances uneven internal forces
2Device complexity
If a solid silica gel strip is used as a buffer, then the structure is simple, but light leakage phenomenon occurs due to inability to balance forces
Solution Approach 1:
The patent changes the physical state parameter of the buffer material from solid to fluid, which enables force redistribution capability. This single parameter change resolves the contradiction by maintaining structural simplicity while eliminating light leakage through improved force balancing
3Ease of manufacture
If the capsule has varying thickness, then manufacturing is easier, but force distribution uniformity is compromised
Solution Approach 1:
The patent specifies that the capsule should have uniform thickness, establishing this as a critical geometric parameter. This parameter specification ensures that the fluid pressure distributes forces uniformly across the capsule walls, resolving the contradiction by prioritizing force distribution uniformity while maintaining manufacturing feasibility

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 buffer structure effectively balances uneven forces by allowing the filler to flow from areas of higher force to lower force, reducing light leakage and improving the display device's stability against deformation-induced stress.
Implementation Method 1
the flowable filler in the hollow part of the buffer structure flows to a position suffering a smaller force from a position suffering a larger force until achieving a force balance
Implementation Method 2
the sealed capsule is made of an elastic material

AI summary
The present disclosure provides a buffer structure and a display device. The buffer structure includes a deformable sealed capsule, and a flowable filler in a hollow part of the sealed capsule. For the buffer structure according to the present disclosure, the hollow part of the deformable sealed capsule is provided with the flowable filler, when the display device suffers uneven internal forces resulting from deformation of the liquid crystal panel or the backboard, the flowable filler in the hollow part of the buffer structure flows to a position suffering a smaller force from a position suffering a larger force until achieving the force balance, thereby to reduce difference of forces at different positions in the display device and further improve light leakage phenomenon caused by uneven forces.
