Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in reducing light leakage while maintaining effective heat dissipation performance, particularly in configurations where heat dissipation layers are used in conjunction with resin and film layers.
Innovation Solution
A display device design that incorporates a heat dissipation layer with graphite, sealed by a cover layer and resin parts, where the heat dissipation layer extends beyond the display layer to cover its sides and is further sealed by a resin part to prevent light leakage, while ensuring efficient heat dissipation through its high conductivity material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat dissipation layer is used to improve heat dissipation performance, then heat dissipation performance is improved, but light leakage occurs
Solution Approach 1:
The device is divided into distinct functional layers: a heat dissipation layer for thermal management and a resin layer for light sealing. This segmentation allows each layer to perform its specific function without interfering with the other, resolving the contradiction between heat dissipation and light leakage prevention
Solution Approach 2:
The resin layer is positioned to cover and seal the heat dissipation layer, creating a nested structure where the sealing function encapsulates the heat dissipation function. This nested arrangement prevents light leakage while preserving the underlying heat dissipation performance
2Object-generated harmful factors
If resin and film layers are added to seal the heat dissipation layer, then light leakage is reduced, but heat dissipation performance deteriorates
Solution Approach 1:
The resin layer is applied locally to cover only the necessary areas around and over the heat dissipation layer to prevent light leakage, while maintaining thermal pathways in other regions. This localized sealing approach prevents light leakage without completely blocking heat dissipation routes
3Temperature
If the heat dissipation layer extends beyond the display layer, then heat dissipation performance is improved, but light leakage increases
Solution Approach 1:
The resin layer is positioned in advance to cover the extended portions of the heat dissipation layer before light leakage can occur. This preliminary sealing action prevents light from escaping through the extended edges of the heat dissipation layer, allowing the layer to extend for better thermal management without causing light leakage

AI summary
A display device includes a display layer including a light emitting element, a heat dissipation part disposed on a rear surface of the display layer, the heat dissipation part including a heat dissipation layer, and a resin part sealing at least a portion of the heat dissipation layer. In a plan view, the heat dissipation layer extends by a same length as the display layer or extends farther than the display layer.
