Lens Layer for Seamless Display Edge Blurring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-size display devices with assembled panels often suffer from visible boundary edges between panels, leading to reduced display quality and a compromised user experience due to the obtrusive appearance of black edges or lines, as existing solutions either degrade brightness or provide limited blurring effects.
Innovation Solution
A display device incorporating a lens layer with elongated lenses that cover the boundary edges, adjusting the brightness of specific pixels adjacent to the frames to enhance light guidance and integration, thereby reducing the visibility of these edges while maintaining consistent image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a lens layer is added to cover boundary edges to blur black edges, then the visual obviousness of frames and gaps is reduced, but the device complexity increases
Solution Approach 1:
A lens layer is introduced as an intermediary component between the display panel and the viewer. This lens layer includes multiple lenses arranged in an array that optically process light from the display panel, specifically blurring the boundary edges and black lines while maintaining image quality in the display area.
Solution Approach 2:
The lens layer is divided into multiple individual lenses arranged in an array, where each lens corresponds to a specific region of the display panel. This segmentation allows selective optical processing - blurring boundary regions while maintaining clarity in central display regions.
2Object-affected harmful factors
If components are added to cover boundary edges, then the obtrusive appearance is reduced, but display brightness and color of the covered area are degraded
Solution Approach 1:
The lens layer applies different optical properties to different regions: lenses positioned over boundary edges provide blurring to reduce visual obviousness, while lenses over the main display area maintain high transmission to preserve brightness and color. This local differentiation allows boundary treatment without sacrificing overall display quality.
3Object-affected harmful factors
If the lens layer covers the boundary edge, then the black edge visibility is reduced, but the display area is reduced
Solution Approach 1:
The lens layer is designed to cover only the necessary boundary regions required for blurring black edges, rather than covering the entire display panel. This partial coverage approach effectively reduces black edge visibility while minimizing the impact on the overall 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
The solution effectively blurs the boundary edges, enhancing the display quality and user experience by improving the consistency and integrity of the image display at the edges, while maintaining or even improving brightness and color consistency.
Implementation Method 1
The lens layer covers the first image adjustment area and the first frame and includes a plurality of lenses arranged side by side and respectively extending in an extending direction of the first frame. The lens layer may be used to receive and guide light to a position on a frame or boundary edge

AI summary
The present invention provides a display device including a first display panel and a lens layer. The first display panel is provided with a first display area and a first frame located at a side of the first display area. The first display area includes a plurality of first pixels, and some of the first pixels form a first image adjustment area adjacent to the first frame. When the first image adjustment area receives a same first image source signal provided to the first display panel, brightness generated by the first pixels in the first image adjustment area is greater than that of the other first pixels in the first display area. The lens layer covers the first image adjustment area and the first frame and includes a plurality of lenses arranged side by side and respectively extending in an extending direction of the first frame.
