Solution Overview
Problem
Conventional quantum dot strips in backlight modules are difficult to replace and prone to damage due to their fixed and narrow installation positions, limiting the enhancement of color gamut saturation and panel quality in liquid crystal displays.
Innovation Solution
A backlight module design featuring a heat dissipation plate with a groove and buffer blocks that facilitate the insertion and securement of a quantum strip, preventing damage and enabling easy replacement, while maintaining optimal spacing with light sources and frames to enhance durability and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the quantum strip is fixed firmly in a narrow installation position, then the quantum strip is protected, but it becomes difficult to replace and easy to damage
Solution Approach 1:
The quantum strip is divided into a quantum dot layer and a substrate, allowing the quantum dot layer to be separated and replaced independently while the substrate remains fixed in the groove, resolving the contradiction between protection and replaceability
Solution Approach 2:
The quantum dot layer is extracted as a replaceable component from the fixed quantum strip assembly, enabling easy replacement of the quantum dot layer without replacing the entire quantum strip structure
2Reliability
If the quantum strip is fixed firmly, then the quantum strip is protected, but it is easily damaged
Solution Approach 1:
Buffer blocks are placed at both ends of the groove to provide cushioning protection for the quantum strip during installation and operation, preventing damage from mechanical stress while maintaining secure positioning
Solution Approach 2:
The quantum dot layer is implemented as a flexible thin film that can be easily replaced, while the rigid substrate provides structural support and protection, creating a composite structure that combines flexibility and strength
