Silicone-Connected Electro-Optical Display Module for Black Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrooptical display modules suffer from black uniformity issues due to pressure exerted by EMC gaskets, requiring additional assembly components like clips and screws, which complicates the mounting process and can lead to defective installations.
Innovation Solution
The first and second elements of the display module are connected using a silicone body, which eliminates the need for additional connecting elements, ensuring a stable and electrical connection while simplifying assembly, and providing thermal management and hermetic sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If EMC gaskets are used to connect elements, then electrical connection is provided, but black uniformity of the display deteriorates due to pressure on the display
Solution Approach 1:
The patent introduces a silicone body as an intermediary connecting element between the first and second elements. This silicone body replaces the traditional EMC gasket and provides both mechanical connection and electrical connection functions. The silicone body has lower stiffness compared to EMC gaskets, which reduces the pressure transmitted to the display panel, thereby maintaining black uniformity while still providing reliable electrical connection between components
Solution Approach 2:
The patent employs a composite material solution by using silicone rubber with embedded conductive particles or conductive fabric within the silicone matrix. This composite material simultaneously provides mechanical flexibility (to reduce pressure on display), electrical conductivity (for grounding and ESD protection), and sealing properties, eliminating the need for separate EMC gaskets and clips
2Reliability
If additional clips and screws are used for assembly, then connection reliability is improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The patent merges multiple functions into a single silicone body component. The silicone body simultaneously serves as a mechanical connector, electrical connector (providing ESD protection and grounding), and sealing element. This consolidation eliminates the need for separate clips, screws, and EMC gaskets, significantly simplifying the assembly process while maintaining or improving connection reliability
Solution Approach 2:
The silicone body is designed as a multi-functional component that performs multiple roles: structural support, electrical grounding, ESD protection, sealing, and pressure distribution. This universal component replaces several specialized components (clips for mechanical attachment, EMC gaskets for electrical protection, seals for sealing), reducing the total number of parts and simplifying both the device structure and assembly process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The silicone connection maintains black uniformity and enhances assembly reliability, reducing mechanical impacts on the display, while offering a stable and conductive link between components.
Implementation Method 1
the connection between the first and second element does not create itself a force impacting the electrooptical display
Implementation Method 2
if the at least one silicone body is made of electrically conductive silicone, a good and long-lasting electrical connection between the first element and second element may be reached
Implementation Method 3
if the first element and the second element are made of metal, the display module is very stable and able to provide a good thermal management by leading heat to an external environment

AI summary
An electrooptical display module comprises an electrooptical display, a first element and a second element. The first element and the second element are connected together and the first element carries the electrooptical display. The first element and the second element are connected by at least one silicone body. In a method for producing an electrooptical display module, silicone is dispensed on at least one of a first element and a second element and then the first element and the second element are brought together so that the silicone connects the first element with the second element and waiting is undertaken until the silicone is set and so a silicone body is formed.
