Heat Diffusing Plate Stepped Support for Display Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display devices, particularly those with organic electroluminescent panels, face heat dissipation challenges that lead to temperature degradation and reduced brightness or contrast, especially in the peripheral regions, due to inefficient heat dissipation mechanisms that also increase the device's thickness.
Innovation Solution
An image display device design featuring a heat diffusing plate on the rear surface of the display panel, supported by a frame that includes a side wall and a support wall, with a stepped portion on the heat diffusing plate to house the support wall, allowing for enhanced heat dissipation without increasing the device's thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat diffusing plate is added to the rear side of the display panel, then heat dissipation properties are improved, but the device thickness increases
Solution Approach 1:
The support wall is nested within the stepped portion of the heat diffusing plate, allowing the support structure to be integrated into the heat dissipation component rather than adding separate structural elements that would increase thickness
Solution Approach 2:
The support wall projects from the side wall in a direction perpendicular to the main thickness direction, providing structural support while minimizing impact on the overall device thickness by utilizing lateral space
2Device complexity
If the frame structure is simplified, then device complexity is reduced, but manufacturing precision may be compromised
Solution Approach 1:
The support wall integrates both structural support function and positioning function in a single component, eliminating the need for separate support brackets or positioning elements that would complicate the frame structure
Solution Approach 2:
The side wall serves multiple functions: providing structural support, positioning the heat diffusing plate, and housing the support wall within its stepped portion, reducing the need for additional specialized components

AI summary
An image display device includes: a display panel which displays an image on a front surface of the display panel; a heat diffusing plate on a rear side of the display panel; and a frame along an edge surface of the display panel and an edge surface of the heat diffusing plate. The frame includes: a side wall which is disposed opposite to the edge surface of the display panel and the edge surface of the heat diffusing plate; and a support wall which projects from the side wall toward the heat diffusing plate. The heat diffusing plate includes a peripheral portion between the support wall and the display panel. The peripheral portion includes, on a rear side, a stepped portion which houses at least part of support wall.
