Display Backplane Substrate Concealment via Protruding Metal Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backplane designs in display devices, such as televisions, fail to effectively hide the substrate layer, which can affect the appearance and require additional components like front or middle frames for concealment, leading to inefficiencies and increased costs.
Innovation Solution
The backplane design incorporates a substrate layer with a honeycomb or wave structure, where a first metal layer with transverse and longitudinal portions protrudes to obscure the substrate, and a latching subassembly for engagement with a frame, allowing the backplane and frame to be securely attached without exposing the substrate, thereby reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a conventional backplane design with a substrate layer is used, then the backplane provides structural support, but the substrate layer is exposed and affects the appearance
Solution Approach 1:
The patent merges the substrate layer with the first metal layer by making the metal layer integrally formed with the substrate, creating a unified backplane structure that provides both structural support and aesthetic appearance without requiring separate components
Solution Approach 2:
The first metal layer serves multiple functions: it provides structural support as part of the backplane, conceals the substrate layer for aesthetic purposes, and forms engagement portions for latching mechanisms, eliminating the need for separate framing components
2Shape
If additional framing components are added to hide the substrate layer, then the appearance is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines the functions of the substrate layer, metal layers, and framing components into a single integrated backplane structure, where the first metal layer's engagement portions directly latch with the frame, eliminating the need for separate adapting pieces or screws
Solution Approach 2:
The first metal layer is designed to perform multiple functions simultaneously: structural support, aesthetic concealment of the substrate, and mechanical engagement with the frame through latching portions, replacing multiple separate components with a single multi-functional element
3Strength
If the backplane and frame are engaged by an adapting piece or screw, then the structural integrity is maintained, but the device complexity increases
Solution Approach 1:
The patent integrates the engagement mechanism directly into the first metal layer, where protruding engagement portions form latching subassemblies that directly interface with the frame, eliminating the need for separate adapting pieces or screws while maintaining structural integrity
Solution Approach 2:
The first metal layer is configured to automatically engage with the frame through its geometric design, where the engagement portions and latching subassemblies work together to secure the backplane to the frame without requiring additional fastening components or complex assembly procedures

AI summary
A backplane for a display device includes a substrate layer, a first metal layer and a second metal layer. The first metal layer protrudes beyond the substrate layer and includes at least one transverse portion and at least one longitudinal portion extending from the transverse portion. The substrate layer is attached on the transverse portion. The second metal layer is attached on the transverse portion. An edge of the substrate layer and an edge of the second metal layer face the longitudinal portion. The longitudinal portion has a length that is greater than or equal to a thickness of the substrate layer and the second metal layer.
