Software Display Size Measurement Using Standard Reference Object
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Matching the size of light control films, such as privacy filters, to display surfaces is challenging due to difficulties in accurately measuring display sizes, leading to confusion for consumers and suboptimal optical properties.
Innovation Solution
A software application measures display size by utilizing a standard-sized object, like an ISO/IEC 7810 ID-1 card, to determine the display height and width, allowing for the selection of the appropriate display film or privacy filter that maximizes optical properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a physical ruler is used to measure display size, then the measurement process is simple, but the measurement precision is insufficient leading to incorrect display size determination
Solution Approach 1:
The patent introduces a standard-sized object (such as a credit card conforming to ISO/IEC 7810 ID-1) as an intermediary reference object. This standard object with known dimensions is displayed on the screen alongside the display content, serving as a mediator between the display and the measurement process. By comparing the pixel dimensions of the standard object to its known physical size, the system can calculate the display's actual dimensions with high precision, resolving the contradiction between measurement precision and process complexity.
Solution Approach 2:
The patent replaces the mechanical measurement system (physical ruler) with a digital/software-based measurement system. The software program automatically captures the display resolution, calculates pixel dimensions of the standard object, and computes the display size through algorithmic processing. This substitution eliminates the imprecision of manual ruler measurements while maintaining simplicity through automated calculation, thereby improving measurement precision without significantly increasing perceived complexity for the user.
2Reliability
If display size is measured inaccurately, then the selection process is simplified, but the optical properties of the display film are suboptimal
Solution Approach 1:
The patent implements a feedback mechanism where the software program not only measures the display size but also uses this measurement information to guide the selection of the appropriate display film. The system provides feedback to the user about the measured display dimensions and recommends specific film sizes that will optimize optical properties. This closed-loop feedback ensures that accurate measurements directly translate into reliable film selection, resolving the contradiction between measurement precision and optical performance reliability.
Solution Approach 2:
The patent performs preliminary measurement and calculation actions before the film selection process. The software program pre-calculates the display dimensions and stores this information for use in the selection process. By performing the measurement action in advance and using it to inform subsequent decisions, the system ensures that the most accurate measurement data is available when making the critical film selection decision, thereby optimizing optical properties without requiring complex real-time measurements during selection.
3Measurement precision
If a standard sized object is used for measurement, then the measurement precision is improved, but the ease of operation decreases due to additional steps
Solution Approach 1:
The patent implements self-service functionality where the software program automatically performs multiple measurement steps without requiring manual intervention. The system automatically captures the display resolution, renders the standard sized object at known dimensions, detects the object's pixel boundaries, and calculates the display size. This automation of routine measurement tasks maintains high measurement precision while significantly improving ease of operation, as the user simply needs to launch the program and follow minimal instructions rather than manually performing complex measurement procedures.

AI summary
A method includes initializing a software program configured to determine a display height and a display width on a display, receiving input dimensions of a standard sized object into the software program, determining the display height and the display width based on the input dimensions of a standard sized object, and outputting the display height and the display width from the software program.
