Solution Overview
Problem
Transparent splicing display devices face issues with uneven brightness and interference with viewing due to the placement of light sources at the periphery, which limits their effectiveness and design flexibility, particularly in achieving a narrow-bezel design.
Innovation Solution
A light source assembly with adjustable light-emitting directions, comprising a base with luminous elements and a light slot with multiple fixing parts, allowing for flexible positioning and orientation to optimize light distribution and reduce peripheral interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light sources are placed at the periphery of transparent splicing display devices, then the display device can be illuminated, but the light sources interfere with viewing and cause uneven brightness
Solution Approach 1:
The patent transitions light source placement from the peripheral plane (2D boundary) to the interior space (3D volume) of the display device. By embedding light sources within the transparent panel structure rather than at its edges, the design eliminates viewing interference while maintaining illumination effectiveness through internal light distribution.
Solution Approach 2:
The patent introduces a light guide layer as an intermediary between the light source and the display content. This mediator distributes light uniformly across the transparent panel, preventing direct observation of light sources while ensuring even illumination, thus resolving both the viewing interference and brightness uniformity issues.
2Adaptability or versatility
If light sources are placed at the periphery, then the structure is simple, but the design flexibility and adaptability to different device sizes are limited
Solution Approach 1:
The patent designs a modular light source assembly that can be configured in multiple orientations (front, rear, left, right) and applied to various transparent splicing display device sizes and configurations. This universal design allows the same basic structure to serve multiple functions and adapt to different applications without requiring complete redesign.
Solution Approach 2:
The patent divides the lighting system into modular components including the light source module, light guide layer, and control circuitry. This segmentation allows independent optimization of each component and enables flexible reconfiguration for different device sizes and requirements, enhancing adaptability while maintaining manageable complexity through standardized modules.
3Ease of operation
If light sources are placed at the periphery, then the structure is simple, but the light-emitting direction cannot be adjusted
Solution Approach 1:
The patent implements adjustable light-emitting directions through movable or reconfigurable light source modules that can be positioned at different locations and orientations within the transparent panel. This dynamic configuration allows the light-emitting direction to be adjusted according to different display requirements while maintaining a relatively simple base structure through modular design.
