Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal panels in televisions are prone to deformation and dark state light leakage due to external forces, as they are fixed by double-sided tapes without space for movement, leading to improper rotation of liquid crystals.
Innovation Solution
A liquid crystal module design where the liquid crystal panel is movably arranged with respect to a first frame, allowing for movement and reducing external force effects, using buffer layers with elastic moduli between 30 Mpa and 100 Mpa to prevent deformation and light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the liquid crystal panel is fixed by double-sided tapes, then the panel is stable and easy to install, but the panel cannot move and is prone to deformation under external forces
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a fixed connection to a movable connection between the liquid crystal panel and the frame. The panel is allowed to move relative to the frame within certain limits, enabling it to adapt to external forces without deformation while maintaining overall structural stability.
Solution Approach 2:
The patent changes the connection parameter from rigid fixation to controlled mobility. By adjusting the degree of freedom in the connection between the panel and frame, the system allows the panel to move within specific parameters (range of motion, displacement limits) to absorb external forces while maintaining operational stability.
2Device complexity
If the liquid crystal panel is fixed rigidly, then the structure is simple and stable, but external forces cause deformation and dark state light leakage
Solution Approach 1:
The patent introduces dynamic movement capability to the previously rigid structure. The panel can move relative to the frame within controlled limits, which prevents deformation under external forces and eliminates dark state light leakage while adding only minimal structural complexity through the movement mechanism.
Solution Approach 2:
The patent applies beforehand cushioning by designing the connection structure to allow pre-calculated movement within specific limits. This movement capability acts as a cushioning mechanism that absorbs external forces before they can cause deformation or light leakage, protecting the panel proactively.
3Object-affected harmful factors
If the liquid crystal panel is allowed to move freely, then external force effects are reduced, but the panel may displace too much and affect display quality
Solution Approach 1:
The patent precisely controls the movement parameters of the panel, allowing it to move within specific limits (range of motion, displacement magnitude) while preventing excessive displacement. This parameter control enables the panel to absorb external forces while maintaining display quality and positional precision.
Solution Approach 2:
The patent applies different constraints to different parts of the panel movement. While the panel is allowed to move freely in certain directions to absorb forces, it is constrained in other directions to maintain position precision. This localized differentiation of movement quality ensures both force absorption and display quality.

Function Achieved in This Case
The design reduces the impact of external forces on the liquid crystal panel, preventing deformation and minimizing dark state light leakage by allowing movement and using buffer layers to absorb stress.
