Variable Pitch Connection Substrate for Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substrates for connecting liquid crystal display panels are not versatile enough to accommodate different sizes or numbers of pixels, leading to increased design processes and costs, as well as the wastage of expensive ICs due to faulty components when trying to share substrates across various specifications.
Innovation Solution
A substrate with variable parts that can change the distance between connection terminal blocks, allowing the same substrate to be used across different sizes or numbers of pixels by folding or slackening these parts, thereby enabling the sharing of substrates and potentially signal processing boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the substrate for connection is designed specifically for each display panel size or pixel number, then the connection reliability is improved, but the device complexity and development costs increase
Solution Approach 1:
The substrate for connection is designed with a variable part that can be configured in multiple ways to accommodate different display panel sizes and pixel numbers. The connection terminal blocks are arranged such that the variable part can be positioned at different locations, allowing a single substrate design to serve multiple display specifications. This universal design approach maintains connection reliability while reducing the need for multiple specialized substrate designs.
Solution Approach 2:
The substrate incorporates a variable part that can be dynamically positioned or configured based on the specific display panel requirements. The variable part includes connection terminal blocks that can be electrically connected to different main body parts depending on the display specification, enabling the substrate to adapt its configuration rather than requiring completely different designs for each application.
2Adaptability or versatility
If multiple substrate designs are prepared for different display specifications, then the adaptability is improved, but the loss of time and manufacturing costs increase
Solution Approach 1:
A single universal substrate design with configurable variable parts replaces the need for multiple specialized substrate designs. The variable part can be positioned at different locations and connected to different main body parts based on the required display specifications, allowing one substrate design to serve multiple display panel sizes and pixel configurations, thereby reducing design process time and manufacturing costs.
Solution Approach 2:
The substrate is divided into a main body part and a variable part that can be independently configured. The variable part contains connection terminal blocks that can be electrically connected to different locations on the main body part depending on the display specification. This segmentation allows flexible reconfiguration without requiring complete redesign, reducing both time and cost.
3Adaptability or versatility
If the variable part is used to change the distance between connection terminal blocks, then the adaptability to different display sizes is improved, but the device complexity increases
Solution Approach 1:
The substrate is segmented into a main body part and a variable part with distinct functions. The variable part specifically contains the connection terminal blocks that need to be repositioned, while the main body part contains the fixed wiring patterns. This segmentation isolates the complexity to only the necessary variable portion, minimizing overall device complexity while maintaining versatility.
Solution Approach 2:
The variable part is designed to enable dynamic reconfiguration of the connection terminal block positions. The variable part can be electrically connected to different locations on the main body part, allowing the substrate to adapt its terminal block spacing to match different display panel sizes and pixel densities without requiring complete structural redesign.
