Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging systems are large, heavy, costly, and power-intensive due to the need for external processing and amplification circuitry and cables to multiplex and demultiplex signals between detectors and displays, which is not suitable for applications requiring minimal size, weight, power, and complexity.
Innovation Solution
An integrated detect and display system where a detector and display are directly vertically integrated, eliminating the need for off-chip processors by using readout and read-in circuitry to directly connect detector and display pixels, reducing weight, size, cost, and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional imaging systems use external processing and amplification circuitry with multiplexing and demultiplexing, then signal processing functionality is achieved, but system size, weight, cost, and power consumption increase
Solution Approach 1:
The patent merges the detector package and display package into a single integrated imaging system. The detector array, readout circuitry, display array, and driver circuitry are combined into one device, eliminating the need for separate external processing circuitry and cables. This merging directly reduces system size, weight, and complexity while maintaining full signal processing functionality through integrated readout and driver circuits.
Solution Approach 2:
The patent transitions from a conventional distributed architecture to a vertically stacked three-dimensional integration. By stacking the detector array, readout circuitry, and display array in vertical layers, the system achieves high integration density. This dimensional change allows all necessary components to be compactly arranged within a small footprint, resolving the contradiction between compact size and functional completeness.
2Weight of moving object
If conventional imaging systems use external cables and interconnections, then electrical connectivity is achieved, but weight and complexity increase
Solution Approach 1:
The patent eliminates external cables and interconnections by merging all electrical connectivity functions into the integrated device. The readout circuitry and driver circuitry are built-in, providing all necessary electrical connections between detector elements, processing circuits, and display elements without requiring external wiring. This integration dramatically reduces system weight and simplifies the electrical interconnection architecture.
3Use of energy by moving object
If conventional imaging systems use multiplexing circuitry, then signal processing is achieved, but power consumption increases
Solution Approach 1:
The patent integrates the multiplexing and demultiplexing functions directly into the readout circuitry and driver circuitry within the imaging device. By combining these signal processing functions into unified integrated circuits rather than separate external components, the system reduces overall power consumption while maintaining full signal processing capability. The integrated architecture allows for more efficient power management and reduced signal transmission losses.
