Anti-static Layer for Display Panel Charge Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The occurrence of brighter and greenish phenomena at the distal end of display panels due to the accumulation of electric charges, leading to quality defects, is not effectively addressed by existing technologies.
Innovation Solution
A display device with a cover member, a display panel, a cushion plate having holes, and an anti-static layer that electrically connects the cover member and cushion plate, dispersing electric charges and reducing the concentration of electric fields by extending along the side surface of the display panel to the inner surface of the cushion plate's holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the bezel area is made thinner to increase user immersion and reduce overall device size, then user immersion and device compactness are improved, but electric charges accumulate more intensively on the distal end side surface of the display panel, causing brighter and greenish phenomena
Solution Approach 1:
An anti-static layer is introduced as an intermediary component between the display panel and the cushion plate. This layer provides a dedicated charge dissipation path that mediates the accumulation of electric charges on the distal end side surface, preventing the brighter and greenish phenomena while maintaining the thin bezel design
Solution Approach 2:
The charge dissipation function is extracted from the existing structural components (cover member and cushion plate) and implemented as a separate anti-static layer. This dedicated layer is specifically designed to address the electric charge accumulation problem without compromising the thin bezel structure
2Object-affected harmful factors
If an anti-static layer is added to dissipate electric charges, then electric charge accumulation is reduced, but the device structure becomes more complex
Solution Approach 1:
The anti-static layer is integrated into the existing cushion plate structure, merging the charge dissipation function with the existing mechanical support structure. The layer is positioned between the display panel and cushion plate, utilizing the existing assembly interfaces without requiring separate mounting structures
Solution Approach 2:
The anti-static layer is implemented as a thin film structure that can be easily integrated into the existing device assembly. This thin film approach provides the necessary charge dissipation function while adding minimal structural complexity and maintaining device compactness
Applied Scientific Principles
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 anti-static layer effectively reduces the accumulation of electric charges, disperses the electric field, and prevents the brighter and greenish phenomena, while also allowing for easy management of the anti-static layer's formation area and thickness, thereby protecting the display panel from cracks.
Implementation Method 1
an anti-static layer formed to electrically connect the cover member and the cushion plate to each other

AI summary
A display device has an anti-static layer extending from a cover member along a side surface of a display panel to an inner surface of a hole of a cushion plate. Thus, a contact area between the anti-static layer and the display panel may be increased, thereby reducing a brighter phenomenon and a greenish phenomenon at a distal end of the display panel.
