Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing display panel support structures for thin and lightweight display modules are prone to damage during maintenance and allow alien substances to enter the backlight device, while also compromising the overall strength and stiffness due to the absence of bezels and lightweight materials.

Innovation Solution

A display module support structure featuring a display panel interposed between a panel chassis and a front cover, with fixing members and buffer members that absorb shocks and prevent dust entry, ensuring the panel's stability and protection during maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If a bezel-less structure is used to achieve a thin and lightweight display module, then the thickness and weight are reduced, but the panel becomes vulnerable to damage during maintenance and allows alien substances to enter the backlight device

Engineering Contradiction:

Improveweight of display moduleVSAvoidpanel protection

Core Design Contradiction:

Weight of moving objectVSReliability

Solution Approach 1:

The support structure is divided into multiple fixing members (first fixing member on front side, second fixing member on rear side) that independently secure the panel at different locations, allowing the panel to be held securely without a continuous bezel frame

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Buffer members are introduced as intermediary elements between the fixing members and the panel, and between the panel and the backlight device. These buffer members provide protection while maintaining the thin profile, preventing direct contact that could cause damage or allow substance ingress

Inventive Principle:

Principle #24Intermediary (Mediator)

2Length of moving object

If bezels are removed to reduce weight and thickness, then the display module becomes thinner and lighter, but the overall strength and stiffness of the display apparatus are reduced

Engineering Contradiction:

Improvethickness of display moduleVSAvoidoverall strength and stiffness

Core Design Contradiction:

Length of moving objectVSStrength

Solution Approach 1:

Instead of a uniform bezel structure, the invention uses localized fixing members positioned at specific critical points (front and rear sides of the panel). These fixing members provide localized support and stiffness where most needed, while maintaining thin dimensions in non-critical areas

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The support structure combines different materials with complementary properties: fixing members made of rigid material for structural support, and buffer members made of elastic or shock-absorbing material for protection. This composite approach provides both strength and shock absorption in a thin profile

Inventive Principle:

Principle #40Composite materials

3Weight of moving object

If a lightweight bezel or panel frame is used to achieve a thin and lightweight display module, then the weight is reduced, but the strength and stiffness are compromised

Engineering Contradiction:

Improveweight of display moduleVSAvoidstrength of support structure

Core Design Contradiction:

Weight of moving objectVSStrength

Solution Approach 1:

The support function is segmented into multiple discrete fixing members rather than a continuous heavy frame. Each fixing member is positioned to provide optimal local support, and the combined effect of multiple strategically placed members provides overall structural integrity without the weight of a complete bezel

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention extracts only the essential support functions from the traditional bezel structure. By removing the continuous frame and retaining only the critical fixing points with buffer members, the design achieves lightweight construction while maintaining necessary strength and protection

Inventive Principle:

Principle #2Taking out (Extraction)

4Ease of repair

If the panel is not connected to the backlight device to enable easy maintenance, then maintenance operations become simpler, but the panel becomes vulnerable to damage and alien substance ingress

Engineering Contradiction:

Improveease of maintenanceVSAvoidpanel protection

Core Design Contradiction:

Ease of repairVSReliability

Solution Approach 1:

The connection between panel and backlight device is segmented into discrete buffer members rather than a continuous fixed structure. This allows the panel to be easily separated for maintenance while the buffer members remain in place to provide ongoing protection when the panel is installed

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Buffer members are pre-installed between the panel and backlight device before maintenance is needed. These buffer members provide continuous protection against alien substance ingress and potential damage even when the panel is not firmly connected to the backlight device, enabling easy maintenance while maintaining protection

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A display module is equipped with a display panel having a display screen for displaying images on a front side of the panel. A panel chassis is provided on a rear side of the display panel with respect to the display screen. The display module is assembled with a plurality of fixing members. Each fixing member has a panel holder to hold the display panel as covering a portion of a periphery of the display screen and a chassis coupling member coupled to the panel chassis so that the display panel is interposed between the panel holder and the panel chassis.
