Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In naked-eye 3D display technology, operational amplifiers corresponding to non-watching areas or unlit sub-pixels are idle, leading to resource wastage and inefficient utilization.
Innovation Solution
A display substrate design with reusing circuits that dynamically connect and disconnect data lines to operational amplifiers, allowing sharing of amplifiers between watching and non-watching areas, and within the same pixel island, to optimize resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If operational amplifiers are allocated to each column of sub-pixels, then the charging rate of sub-pixels is improved, but the resource utilization of operational amplifiers deteriorates due to idle amplifiers in non-watching areas
Solution Approach 1:
The patent implements reusing circuits that enable operational amplifiers to serve multiple functions: they can charge sub-pixels in watching areas during first time periods and charge sub-pixels in non-watching areas during second time periods. This multi-functionality allows the same operational amplifier resource to be utilized across different spatial regions and time intervals, resolving the contradiction between maintaining high charging rates and improving resource utilization.
Solution Approach 2:
The patent introduces dynamic switching mechanisms through reusing circuits and control circuits that can dynamically reconfigure the connection between operational amplifiers and data lines. The system transitions from a static one-to-one mapping to a dynamic many-to-many relationship, allowing operational amplifiers to be reallocated based on temporal and spatial requirements, thereby improving both charging performance and resource utilization simultaneously.
2Loss of energy
If reusing circuits are introduced to share operational amplifiers, then resource utilization is improved, but the circuit complexity increases
Solution Approach 1:
The patent merges the functions of multiple operational amplifiers through reusing circuits, allowing a single operational amplifier to control multiple data lines that connect to different pixel columns. This consolidation reduces the total number of operational amplifier instances needed while maintaining full functionality, thereby improving resource utilization without proportionally increasing circuit complexity.
Solution Approach 2:
The reusing circuit acts as an intermediary component between operational amplifiers and data lines, providing intelligent routing and switching capabilities. This intermediary layer abstracts the complexity of resource sharing, allowing operational amplifiers to be dynamically allocated to different data lines based on temporal and spatial requirements without requiring complex direct connections between all components.
3Quantity of substance
If operational amplifiers are reused across different pixel columns, then the number of operational amplifiers is reduced, but the control complexity increases
Solution Approach 1:
The patent segments the control of operational amplifiers into distinct time periods (first time periods for watching areas, second time periods for non-watching areas) and spatial zones (different pixel columns and rows). This segmentation allows the same operational amplifier to be controllably assigned to different data lines at different times, reducing the total number of amplifiers needed while managing control complexity through structured temporal and spatial division.
Solution Approach 2:
The patent implements periodic switching of operational amplifier assignments between different data lines and pixel columns. During first time periods, operational amplifiers serve watching area sub-pixels; during second time periods, they serve non-watching area sub-pixels. This periodic action pattern creates a predictable, rhythmical control scheme that reduces component count while keeping control logic manageable through regular temporal segmentation.
