LCD Panel Charge Neutralization via Press-Activated Conductive Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display panels suffer from residual electric charge ions accumulating on substrates, causing a ghost shadow effect due to the electric field generated after voltage removal, which degrades viewing quality and display effect.
Innovation Solution
Incorporating first and second transparent conductive layers on the inner sides of the substrates, with a connecting component, such as a resin protrusion, that only electrically connects the layers when pressed, neutralizing the electric charges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional liquid crystal display panels are used without additional conductive layers, then the manufacturing process is simple, but residual electric charge ions accumulate on substrates causing ghost shadow effects that degrade display quality
Solution Approach 1:
The conductive layer is segmented into multiple transparent conductive layers positioned at different substrates. Each layer is independently configured to introduce opposite polarity electric charges, allowing separate control and neutralization of residual charges on each substrate without requiring complete redesign of the entire display structure
Solution Approach 2:
A connecting component serves as an intermediary element that electrically connects the first and second transparent conductive layers. This mediator enables charge neutralization between layers while maintaining the overall structure's integrity and allowing the system to function with minimal modifications to conventional display architecture
2Object-affected harmful factors
If transparent conductive layers are added to neutralize electric charges, then display quality improves by preventing ghost shadow, but device structure becomes more complex
Solution Approach 1:
The connecting component serves multiple functions simultaneously: it electrically connects the transparent conductive layers for charge neutralization, maintains the structural integrity of the display panel, and may serve as a spacer or support element. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in structural complexity
Solution Approach 2:
The transparent conductive layers are positioned specifically at the inner sides of substrates where residual charge accumulation occurs. The connecting component is strategically placed to establish electrical connections only where needed for charge neutralization, rather than uniformly across the entire display structure, thus minimizing unnecessary complexity

AI summary
A liquid crystal display (LCD) panel and an LCD device are provided. The panel has: a first transparent conductive layer configured to introduce a first polarity electric charge accumulated on a first substrate, a second transparent conductive layer configured to introduce a second polarity electric charge accumulated on a second substrate, and a connecting component disposed on the first substrate and/or the second substrate. Only when pressing the liquid crystal display panel, the first transparent conductive layer and the second transparent conductive layer are electrically connected to each other by the connecting component.
