Antistatic Pattern Nesting for AMOLED Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high production cost of active-matrix organic light emitting diode (AMOLED) display apparatuses is attributed to the use of copper as the material for antistatic layers, which are costly and inefficient when used as entire layers.
Innovation Solution
The implementation of a display apparatus with a first antistatic pattern and a second antistatic pattern in an electronic component, such as a near field communication chip, provided in a nesting manner on the display panel, reducing the overall amount of antistatic material required and thus the production cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an entire layer of copper is used as the antistatic layer, then the antistatic functionality is improved, but the production cost increases due to the high price of copper
Solution Approach 1:
The patent divides the antistatic layer into two separate patterns: a first antistatic pattern on the display panel and a second antistatic pattern on the electronic component. This segmentation allows each pattern to serve a specific antistatic function rather than requiring a complete copper layer, thereby reducing the total amount of copper material needed while maintaining overall antistatic effectiveness.
Solution Approach 2:
The patent implements a nested structure where the second antistatic pattern on the electronic component is positioned within the projection area of the first antistatic pattern on the display panel. This nesting arrangement allows both patterns to cooperate in providing antistatic protection, enabling the system to achieve the required antistatic functionality with reduced material quantity by utilizing the spatial overlap and cooperative effect of the two patterns.
2Reliability
If an entire layer of copper is used as the antistatic layer, then the antistatic functionality is improved, but the production cost increases
Solution Approach 1:
The patent segments the antistatic function across two separate components (display panel and electronic component) rather than using a single complete copper layer. This segmentation reduces the total copper material required, directly lowering production costs while maintaining the necessary antistatic protection through the cooperative effect of both patterns.
Solution Approach 2:
By nesting the second antistatic pattern within the projection area of the first antistatic pattern, the patent creates a cooperative antistatic system that achieves effective protection with reduced material usage. This nested configuration optimizes material efficiency and reduces production costs associated with copper procurement and processing.
3Quantity of substance
If a first antistatic pattern and a second antistatic pattern are provided in a nesting manner, then the amount of antistatic material is reduced, but the device structure becomes more complex
Solution Approach 1:
The patent makes the electronic component serve dual functions: it provides its own antistatic protection through the second antistatic pattern while simultaneously contributing to the overall antistatic protection of the display apparatus by nesting within the first antistatic pattern. This multi-functionality approach integrates the antistatic function into an existing component rather than adding a separate structure, thereby reducing material usage without significantly increasing device complexity.
