Rigid Body Load Distribution in Flat Panel Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flat panel displays, such as LCDs, face challenges when mounted in non-vertical positions due to the inability to accommodate significant loads without external housing structures, which can lead to poor viewing experiences and damage from external forces, especially when using thicker protective surfaces that cause parallax and fragility of backlighting components.
Innovation Solution
A flat panel display structure featuring a peripheral frame with a rigid body and base that supports video display layers, distributing applied loads to the frame, eliminating the need for external housing and protecting backlighting components by integrating a light transmissive rigid support with diffusers and filling material to ensure uniform backlighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an external housing structure with thick protective surface is used, then the display can support significant loads, but parallax and viewing angle problems worsen
Solution Approach 1:
The patent moves the protective function from the front viewing surface to the rear support structure. By placing a rigid support structure behind the display and distributing loads through the frame, the front surface can remain thin and optically clear, eliminating parallax while maintaining load support capability through structural redistribution in the depth dimension.
Solution Approach 2:
The patent introduces a rigid support structure as an intermediary between the display and the external loads. This mediator absorbs and distributes forces before they reach the display surface, allowing the front protective layer to be thin without compromising strength, thus resolving the contradiction between load support and viewing quality.
2Reliability
If an external housing structure is used to protect the display, then the display can withstand external forces, but the structure complexity increases
Solution Approach 1:
The patent merges the protective housing structure with the display assembly itself. The rigid support and frame are integrated as internal components rather than external additions, providing protection while maintaining a streamlined, unified structure that reduces overall complexity.
Solution Approach 2:
The frame and rigid support structure serve multiple functions simultaneously: they provide structural integrity, distribute loads, protect internal components including backlighting, and eliminate the need for separate external housing. This multi-functionality reduces overall device complexity while maintaining reliability.
3Reliability
If a protective structure is added to protect backlighting tubes, then the backlighting components are protected from damage, but obstructions are introduced that interfere with uniform backlighting
Solution Approach 1:
The patent extracts the backlighting protection function from the front viewing area and relocates it to the rear support structure. By providing protection behind the display rather than in front, the system maintains both component protection and unobstructed light paths for uniform backlighting.
Solution Approach 2:
The rigid support structure acts as an intermediary that protects backlighting components from external forces without interfering with light emission. Positioned behind the display, it shields fragile tubes while leaving the optical path clear, thus maintaining uniform illumination.
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 allows flat panel displays to withstand significant loads without fracturing, maintains a clear viewing experience by minimizing parallax, and protects backlighting components from damage, enabling their use in non-vertical applications like advertising or tabletop displays.
Implementation Method 1
when a load is applied to the surface of the video layers, the force of the load is transferred to the rigid body and distributed to the peripheral frame
Implementation Method 2
integrating a light transmissive rigid support with diffusers and filling material to ensure uniform backlighting
Implementation Method 3
integrating a light transmissive rigid support with diffusers and filling material to ensure uniform backlighting
Data Source
AI summary
A flat panel display structure is disclosed that can support significant loads on the viewing surface without fracturing or permanently damaging the video display. A rigid body is fitted in a peripheral frame and situated behind the viewing surface. When a load is applied to the video display, the load is transferred to the rigid body, which absorbs and distributes the load to the peripheral frame.
