Display Device Ordinate-Abscissa Value Pair Resolution Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with discrete display points suffer from limited resolution, leading to a loss of information and accuracy in measured values, particularly in real-time data acquisition and display, due to reduced resolution in the abscissa direction.
Innovation Solution
The method involves determining the maximum and minimum ordinate values within a half spacing distance of each abscissa value and replacing individual ordinate-abscissa value pairs with interpolated values, ensuring that the increased resolution of measured values is maintained during display without losing information, using a quatizer, interpolator, and extreme-value former to process discrete logged level values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the resolution of measured values is reduced to match the display device resolution, then the display can be implemented on standard display devices, but information loss and accuracy degradation occur in the measured values
Solution Approach 1:
The patent transitions from displaying individual ordinate-abscissa value pairs to displaying area representations that encompass multiple value pairs. By representing ranges of measured values as areas with boundaries indicating minimum and maximum values, the system preserves high-resolution measurement information while adapting to low-resolution display constraints. This dimensional transformation allows the display to convey more information within the limited pixel grid.
2Measurement precision
If individual ordinate-abscissa value pairs are displayed, then precise measurement information is preserved, but the display device cannot resolve the details due to limited display points
Solution Approach 1:
The patent merges multiple ordinate-abscissa value pairs into single area representations. Each area combines information from multiple measured value pairs by determining minimum and maximum ordinate values across the range of abscissa values, effectively consolidating high-resolution measurement data into displayable units that preserve the essential value range information without requiring corresponding high-resolution display points.
3Measurement precision
If the FFT length is increased to improve abscissa direction resolution, then measurement accuracy improves, but the display device still cannot display the increased resolution due to fixed pixel count
Solution Approach 1:
The patent introduces an intermediary processing step that transforms high-resolution measurement data into area representations suitable for low-resolution display. This intermediary representation layer, which calculates minimum and maximum values across ranges of measured data, acts as a mediator between the high-resolution measurement system (FFT transformer) and the low-resolution display device, allowing the full measurement resolution to be maintained in the data while adapting to display constraints.

AI summary
A method for displaying ordinate-abscissa value pairs on a display device with discrete display points in the abscissa and ordinate direction, of which the abscissa resolution is reduced by comparison with the abscissa resolution of the ordinate-abscissa value pairs, determines the respective maximum and minimum ordinate value of every ordinate-abscissa value pair, which is disposed within the half spacing distance of the abscissa value relative to the adjacent abscissa value to the right and left of the display points, and replaces all ordinate-abscissa value pairs, which are disposed within the half spacing distance of the respective abscissa value relative to the respective adjacent abscissa value to the right and left of the display points, with an area between the maximum and the minimum ordinate value and the half spacing distance of the abscissa value relative to the adjacent abscissa value to the right and left of the display points.
