Display Panel Common Electrode Extraction for Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current full screen technology allows water and oxygen to intrude into the display area along the common electrode layer of OLED display panels, compromising their integrity.
Innovation Solution
A display panel design featuring a non-display area, a display area, a transparent area, and an aisle area, where the common electrode layer is not present in the transparent and aisle areas, ensuring it remains protected by other film layers even when the transparent area is cut to form a through-hole, thereby preventing water and oxygen intrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display panel is hollowed out to accommodate electronic components, then the lighting effects of electronic components are ensured, but water and oxygen would intrude the display area along the common electrode layer
Solution Approach 1:
The common electrode layer is extracted from the transparent area and aisle area, creating a discontinuous structure that prevents water and oxygen from traveling along this layer into the display area, while still allowing the transparent area to be hollowed out for electronic components
Solution Approach 2:
The common electrode layer is segmented into multiple discrete regions rather than forming a continuous layer across the transparent area, which breaks the potential intrusion path for water and oxygen while maintaining functionality in the display area
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
This design effectively prevents water and oxygen from entering the display area through the common electrode layer, enhancing the waterproof and oxygen-proof performance of the display panel.
Implementation Method 1
the encapsulation layer is disposed on the substrate... effectively prevents water and oxygen from entering the display area
Implementation Method 2
some film layers of light-emitting functional layers, such as a common electrode layer, form a whole layer by evaporation

AI summary
The present disclosure provides a display panel and a mask. The display panel does not dispose a common electrode layer in a transparent area and an aisle area, and by this way, after the transparent area of the display panel is cut to form a through-hole, the common electrode layer can still be protected by other film layers and not be directly exposed to air, thereby preventing intrusion of water and oxygen.
