Liquid Crystal Module FPC Derivation Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing liquid crystal modules face challenges with the miniaturization of electronic apparatus due to bending issues and conduction failures between FPC substrates, particularly when the derivation portion of the FPC substrate for an LED is bent, which complicates the incorporation and electrical connection process.
Innovation Solution
The derivation portion of the FPC substrate for an LED is derived from a position closer to the liquid crystal display panel than to the bottom surface of the case, allowing it to extend outside the backlight unit, reducing bending and increasing the radius of curvature, thus improving the miniaturization and incorporation of the liquid crystal module into electronic apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the derivation portion of the FPC substrate for LED is bent to fit into the liquid crystal module, then the module can be compacted, but conduction failures occur between FPC substrates
Solution Approach 1:
The derivation portion of the FPC substrate for LED is preliminarily positioned to extend outside the backlight unit before final assembly, allowing electrical connections to be established in advance without subsequent bending that would cause conduction failures
Solution Approach 2:
The derivation portion extends in a different spatial dimension (outside the backlight unit) rather than being confined within it, allowing connections to be made without bending the substrate through the module structure
2Length of moving object
If the FPC substrate for LED is folded for incorporation, then miniaturization is achieved, but bending issues compromise electrical connections
Solution Approach 1:
Instead of folding the FPC substrate inward into the module, the derivation portion is extended outward outside the backlight unit, inverting the conventional approach to avoid bending while achieving compact integration
3Ease of operation
If the derivation portion extends parallel to the display surface, then electrical connection is simplified, but the module size increases
Solution Approach 1:
The derivation portion is positioned outside the backlight unit in a different spatial arrangement, allowing it to extend without increasing the front display surface area while maintaining ease of connection
