Display Panel Opaque Layer for Ghost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels face challenges in optimizing the display area around electronic components, where the presence of these components can restrict image quality due to reduced light transmittance and potential ghost or flare effects, especially when used in applications like cameras.
Innovation Solution
The display panel design incorporates a second pixel circuit and electrode in a peripheral area, with an opaque layer and organic insulating layers to absorb light reflections, ensuring high transmittance and minimizing ghost or flare effects by positioning the pixel circuit outside the component area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If an opaque layer is added to block light reflections from electronic components, then ghost or flare effects are reduced, but light transmittance is reduced and image quality deteriorates
Solution Approach 1:
The patent applies local quality by making only specific regions opaque rather than the entire component area. The opaque layer is selectively positioned only where light reflections from electronic components would cause ghost or flare effects, while other regions maintain transparency to allow light transmission. This resolves the contradiction by locally blocking harmful reflections without globally reducing light transmittance.
2Area of stationary object
If the pixel circuit is positioned in the component area to improve display coverage, then display area is expanded, but light transmittance is reduced due to component presence
Solution Approach 1:
The patent resolves the spatial conflict by moving the pixel circuit from the planar component area to a different dimensional space - specifically, positioning it in a peripheral area or on a different layer level. This dimensional repositioning allows the pixel circuit to be electrically connected to pixels in the component area while physically located where it does not block light transmission, thus expanding display coverage without sacrificing light transmittance.
