Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Micro OLED display modules face issues such as edge breakage or scratching of the display chip due to exposure to air during assembly and use, leading to product failure, and poor heat dissipation, especially in large-size modules.
Innovation Solution
A display module design featuring a frame body on the circuit board with a fixing adhesive covering the non-display region of the display panel, and a heat dissipation plate replacing part of the circuit board to protect the display chip and improve thermal management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display chip is exposed to air during assembly and use, then the assembly process is simple, but the display chip is prone to edge breakage or scratching
Solution Approach 1:
A frame body is introduced as an intermediary structure between the display panel and the external environment. The frame body forms a protective cavity that isolates the display chip from direct exposure to air and mechanical damage during assembly and use, while still allowing the assembly process to remain relatively simple
2Device complexity
If the display chip is exposed to air, then the structure is simple, but heat dissipation is poor
Solution Approach 1:
The frame body is merged with a heat dissipation plate to form an integrated structure. This combination achieves both protective and thermal management functions simultaneously - the frame body provides mechanical protection while the heat dissipation plate conducts heat away from the display chip, improving heat dissipation performance without significantly increasing structural complexity
Solution Approach 2:
The frame body is designed to perform multiple functions: it provides mechanical support, protects the display chip from damage, facilitates heat dissipation, and structural isolation. This multi-functionality addresses both the protection and heat dissipation requirements without requiring separate dedicated components for each function
3Ease of operation
If the display chip is exposed to air, then the assembly process is straightforward, but edge breakage and scratching occur
Solution Approach 1:
The frame body is installed beforehand to form a protective cavity structure that cushions and shields the display chip from potential mechanical damage during subsequent assembly operations and use. This preventive measure protects against edge breakage and scratching before they can occur
