Solution Overview

Problem

Existing display devices face the challenge of direct heat transfer from electrical components to the display panel, which can compromise the integrity and performance of the panel without complex heat management solutions.

Innovation Solution

The display device incorporates an inner plate with an insulation region having a lower heat transfer coefficient than the plate body, featuring insulating through holes to create an air gap between electrical components and the panel, and a rear chassis with heat transfer portions to manage heat dispersion effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of stationary object

If the display device uses a thin structure to reduce thickness, then the thickness of the display device is reduced, but heat generated by electrical components directly transfers to the display panel

Engineering Contradiction:
Improvethickness of display deviceVSAvoidheat transfer to display panel
Core Design Contradiction:
Length of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an inner plate with insulation regions as an intermediary component between the electrical components and the display panel. This inner plate includes heat transfer portions with lower heat transfer coefficients that block direct heat paths from electrical components to the display panel, while allowing thermal management through controlled heat dissipation paths.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The inner plate is segmented into different regions with different thermal properties: heat transfer portions with lower heat transfer coefficients for insulation and other portions for heat dissipation. This segmentation allows the structure to simultaneously achieve thermal isolation and thermal management functions.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If insulation regions are added to block heat transfer, then heat transfer to display panel is reduced, but the structure becomes more complex

Engineering Contradiction:

Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the thermal management function into the existing inner plate structure by creating regions with different heat transfer coefficients within the same component. This integration avoids adding separate insulation components and maintains structural simplicity while achieving effective heat blocking.

Inventive Principle:
Principle #5Merging (Combining)

3Object-affected harmful factors

If insulating through holes are formed in the inner plate, then heat transfer is reduced through air gap formation, but manufacturing complexity increases

Engineering Contradiction:
Improveheat transfer to display panelVSAvoidmanufacturing process complexity
Core Design Contradiction:

Solution Approach 1:

The patent replaces complex multi-component insulation structures with a simplified inner plate that uses insulating through holes to create air gaps. This mechanical design substitution achieves effective thermal isolation through straightforward hole formation processes, reducing manufacturing complexity compared to traditional multi-layer insulation systems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
