Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices with narrow bezels face limitations in achieving a lightweight, thin profile while maintaining a wide display area and minimizing non-display areas, and there is a need to reduce process costs and improve efficiency.
Innovation Solution
A display device design that integrates a light source unit, a reflective plate, and optical unit with modular films to reduce material costs and eliminate the need for a guide panel and glass diffusion plate, allowing for a lightweight, thin profile, and narrow bezel, while maintaining high light transmittance and preventing sagging through the use of specific module films and adhesive layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If a top cover is removed and display panel is attached to guide panel through adhesive pad, then weight is reduced and profile is thinned, but bezel width cannot be sufficiently narrowed
Solution Approach 1:
The invention divides the support structure into multiple functional layers: cover bottom with side surface, first module film for optical unit support, and second module film for display panel support. This segmentation allows each layer to be optimized independently, enabling narrower bezel while maintaining structural integrity and reducing overall weight compared to traditional single-plate guide panel designs.
Solution Approach 2:
The invention utilizes the vertical dimension by creating a stepped structure where the first module film extends further laterally than the second module film. This dimensional arrangement allows the optical unit to be supported beyond the display panel's edge, effectively narrowing the visible bezel area while maintaining proper support, thus converting a 2D support problem into a 3D spatial solution.
2Stability of the object's composition
If traditional guide panel and glass diffusion plate are used, then structural stability is maintained, but material cost and process complexity increase
Solution Approach 1:
The invention merges the functions of the guide panel and glass diffusion plate into an integrated module film structure. The first and second module films collectively provide both structural support and optical diffusion functions that were previously separated into multiple components, thereby reducing material cost and simplifying the manufacturing process while maintaining structural stability.
Solution Approach 2:
The module films serve multiple functions simultaneously: they provide mechanical support for the optical unit and display panel, act as diffusion plates for light distribution, and serve as adhesive layers for bonding. This multi-functionality eliminates the need for separate guide panels and glass diffusion plates, reducing both material cost and process complexity while maintaining structural integrity.
3Ease of manufacture
If module films are used to support optical unit and display panel, then material cost is reduced and process efficiency is improved, but light transmittance and sagging prevention must be maintained
Solution Approach 1:
The invention employs composite module films that integrate multiple properties: transparency for light transmittance, appropriate thickness and material composition for mechanical strength to prevent sagging, and adhesive properties for bonding. This composite material approach allows the films to simultaneously meet optical performance requirements and structural reliability requirements while simplifying manufacturing compared to traditional multi-component assemblies.
