Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices have a significant non-display area that obstructs optical signals, limiting their functionality and aesthetics, particularly in portable electronic devices with diverse functions.
Innovation Solution
A display device design featuring a hole in the display panel with a compensation layer and division patterns around the hole, allowing for a reduced non-display area and enhanced optical signal transmission, while maintaining structural integrity and display functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional display panel structure is used with solid non-display areas, then structural integrity is maintained, but optical signal transmission is obstructed and display area is reduced
Solution Approach 1:
The patent extracts the non-display area by creating a hole that passes through multiple layers (base layer, circuit layer, light emitting element layer) to allow optical signals to pass through. This removes the obstructing material in the non-display region, enabling optical signals to transmit through what would traditionally be solid non-display areas, thereby increasing the effective display area and optical transmission without compromising the overall structural integrity of the display panel.
2Illumination intensity
If a hole is created to pass optical signals through the display panel, then optical signal transmission is improved, but structural integrity and layer alignment may be compromised
Solution Approach 1:
The patent introduces a compensation layer as an intermediary element that fills the hole and overlaps with it. This compensation layer acts as a mediator that maintains the structural integrity of the display panel while allowing optical signals to pass through. The compensation layer is disposed on the light emitting element layer and overlapping the hole, providing structural support and maintaining layer alignment without obstructing the optical signal transmission path.
Solution Approach 2:
The patent segments the hole region into multiple functional zones by introducing division patterns (first division pattern, second division pattern, third division pattern) that are sequentially arranged and spaced apart around the hole. These division patterns are disposed on the base layer and help to segment the structural support function from the optical transmission function, allowing the hole to maintain structural integrity while enabling optical signal passage.
3Stability of the object's composition
If division patterns are added around the hole to maintain structural integrity, then layer alignment is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the structural support function into multiple discrete division patterns (first, second, and third division patterns) that are sequentially arranged around the hole. These patterns are spaced apart from each other and disposed on the base layer, providing distributed structural support that maintains layer alignment without requiring a continuous complex structure. The segmentation allows each pattern to be independently formed while collectively maintaining overall structural integrity.
