L-Shaped Support Member for Flexible Lighting Unit Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transparent display devices have limited flexibility in positioning their lighting units due to fixed mounting structures, which restricts their application in larger display screens and varied display panel configurations.
Innovation Solution
The proposed display device incorporates a lighting unit with a support member having an L-shaped cross section, allowing the light source and light guide to be fixed on different sides of the support member. This configuration enables the lighting unit to be securely attached to a transparent substrate or display panel, providing flexibility in positioning and mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed mounting structure is used for the lighting unit, then the mounting position is stable and reliable, but the positioning flexibility is limited
Solution Approach 1:
The lighting unit is divided into separate components (light source, light guide, support member) that can be independently positioned and assembled. The support member has a specific mounting structure that separates the fixation function from the positioning function, allowing the lighting unit to be securely mounted while maintaining positioning flexibility through the L-shaped cross section design.
Solution Approach 2:
The support member is designed with an L-shaped cross section that extends in multiple directions, adding spatial dimensions to the mounting capability. This L-shaped structure provides multiple mounting surfaces and orientation options, enabling the lighting unit to be fixed reliably while adapting to different positions and angles on the display panel.
2Device complexity
If the light source and light guide are mounted on the same side of the support member, then the structure is simpler, but the mounting flexibility and adaptability to different display configurations is reduced
Solution Approach 1:
The light source and light guide are positioned on different sides of the support member, segmenting their spatial arrangement. This separation allows each component to be optimally positioned for its function while the support member provides the structural connection, achieving both functional optimization and mounting flexibility.
Solution Approach 2:
By placing the light source and light guide on opposite sides of the support member along different spatial dimensions, the design achieves better light path control and mounting adaptability. The L-shaped support member provides spatial separation that enables flexible configuration for different display panel sizes and types.

AI summary
A display device includes a display panel including a polymer-dispersed liquid crystal layer between a pair of substrates, a transparent substrate disposed on at least one side of the display panel, and a lighting unit configured to project light from the side of the transparent substrate. The lighting unit includes at least one light source, at least one light guide incident with the light emitted from the light source, and a support member having an L-shaped cross section and extending along one side of the display panel to which the at least one light source and the at least one light guide are fixed. The at least one light source and the at least one light guide are disposed on different sides of the support member. The lighting unit is fixed to the transparent substrate or the display panel by the support member.
