Copy Light Emitting Element for Display Boundary Masking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with display panels face challenges in minimizing the visibility of boundaries between light emitting areas of different shapes, leading to noticeable dark lines that affect the overall display quality.
Innovation Solution
The electronic device incorporates a display panel with a unique configuration, including a base layer, circuit layer, element layer, and encapsulation layer, where a copy light emitting element is placed in the intermediate area between areas of different light emitting elements, and a driving chip stores coordinates and brightness compensation values to enhance brightness and reduce boundary visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different shaped light emitting areas are used to accommodate electronic modules, then functional integration is improved, but boundary visibility between areas increases
Solution Approach 1:
A copy light emitting element is introduced as an intermediary between the first light emitting area and the second light emitting area. This copy element replicates the appearance and light emission characteristics of adjacent light emitting areas, serving as a visual bridge that masks the boundary between different shaped areas while maintaining functional independence of each region.
Solution Approach 2:
The copy light emitting element is strategically positioned only at the boundary region between different light emitting areas, while other regions maintain their original light emitting characteristics. This localized application addresses boundary visibility without affecting the overall functional design of different shaped light emitting areas.
2Object-affected harmful factors
If copy light emitting element is added in intermediate area, then boundary visibility is reduced, but device complexity increases
Solution Approach 1:
Instead of creating a completely new light emitting structure, the invention uses a copy light emitting element that replicates the appearance and light emission characteristics of existing light emitting areas. This copying approach achieves boundary masking with minimal additional complexity by reusing proven design elements.
Solution Approach 2:
The copy light emitting element is electrically connected to the same driving circuit as adjacent light emitting areas, merging control functions. This integration reduces the need for separate control circuits and minimizes additional complexity while achieving the boundary masking effect.
