Elastic Frame Supporting Structure for Display Panel Light Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display panels experience light leakage due to uneven thickness caused by external forces, which is exacerbated in narrow-frame, large-size displays, and existing solutions to reduce this issue often compromise transmittance or response time.
Innovation Solution
Incorporating a frame supporting structure with an elastic material in the display panel's frame area, which deforms uniformly under external pressure, maintaining even thickness and reducing light leakage, while also avoiding issues like high temperature shorts and horizontal stripes associated with conventional frame sealants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional frame sealant is used to seal the first substrate and the second substrate, then the sealing performance is ensured, but light leakage occurs due to uneven thickness caused by external forces
Solution Approach 1:
The patent changes the material parameter of the frame supporting structure from conventional rigid sealant to elastic material with specific elastic recovery rate (above 80%). This parameter change enables the structure to dynamically respond to external forces, maintaining uniform thickness and preventing light leakage while preserving sealing performance.
Solution Approach 2:
The patent introduces dynamic characteristics by using elastic material that can deform and recover under external forces. The frame supporting structure dynamically adjusts its shape to maintain uniform cell gap thickness, converting from a static rigid structure to a dynamic adaptive structure that responds to pressure changes.
2Area of stationary object
If the display panel is made with narrow frame area and large display area, then the display size is increased, but light leakage is exacerbated due to uneven thickness
Solution Approach 1:
The patent applies local quality by providing frame supporting portions at specific locations where thickness uniformity is critical. The elastic supporting structures are strategically positioned in the frame area to provide localized support, enabling large display areas while preventing light leakage through targeted reinforcement.
3Strength
If conventional frame sealant is used to support the thickness of the periphery, then the structural support is provided, but high temperature shorts and horizontal stripes occur
Solution Approach 1:
The patent uses composite material structure consisting of elastic material with specific properties (elastic recovery rate above 80%). This composite approach combines the benefits of flexibility and structural support, providing thickness support while avoiding the thermal and electrical issues associated with conventional sealant materials.
