QR Code Readability on Natural Material Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying two-dimensional codes, such as QR codes, face challenges in maintaining clear visibility when using natural materials like wood, as they can be obscured by the texture of the material, leading to reading errors, and require complex updates, while liquid crystal displays may not fit the atmospheric context and can have brightness issues.
Innovation Solution
A display method using a thin layer of natural or synthetic materials on a casing with a display panel that allows for the two-dimensional code to be moved or rotated to correct display failures, incorporating error correction capabilities and short-range wireless communication for updating, ensuring clear visibility and harmony with the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a two-dimensional code is displayed on a liquid crystal display, then the display content can be easily updated, but the display device may not fit the atmospheric context and can have brightness issues
Solution Approach 1:
The patent uses a camera to capture an image of the two-dimensional code displayed on the natural material surface, creating a digital copy that can be processed and corrected. This allows the system to verify and correct the displayed code without physically changing the natural material surface, thus maintaining atmospheric harmony while enabling content updates.
Solution Approach 2:
The system adjusts the brightness and contrast parameters of the captured two-dimensional code image to ensure readability against the natural material background. By dynamically adjusting these display parameters, the system maintains atmospheric harmony while ensuring the code remains readable under varying lighting conditions.
2Adaptability or versatility
If a two-dimensional code is printed on a paper medium and pasted on the side of each work, then the display can be updated, but the process is complicated and troublesome
Solution Approach 1:
Instead of physically replacing paper media, the system captures a digital copy of the two-dimensional code displayed on the natural material surface using a camera. This digital copy can be easily stored, transmitted, and updated without any physical manipulation of the display medium, greatly simplifying the update process.
Solution Approach 2:
The patent replaces the mechanical process of printing and pasting paper media with an electronic imaging and data processing system. The camera captures the displayed code, and digital processing techniques handle storage and updates, eliminating the need for physical material handling and reducing operational complexity.
3Object-affected harmful factors
If the surface of the display device is made of a natural material such as wood, then it can be fit in with the atmosphere of the place, but the two dimensional code may become unclear or inaccurate, resulting in reading errors
Solution Approach 1:
The system uses a camera to capture a high-resolution digital copy of the two-dimensional code displayed on the natural material surface. This digital copy allows for verification and correction of any reading errors caused by the natural material's texture or color variations, ensuring accurate code recognition while maintaining atmospheric harmony.
Solution Approach 2:
The patent implements a feedback mechanism where the captured image of the two-dimensional code is analyzed to detect potential reading errors. If errors are detected, the system can adjust the display parameters or re-capture the code, ensuring accurate reading while maintaining the natural material surface that provides atmospheric harmony.
4Use of energy by moving object
If a two-dimensional code is displayed on a natural material surface, then the display device can be turned off to save energy, but display performance may be degraded due to material variations
Solution Approach 1:
The system captures a digital copy of the two-dimensional code displayed on the natural material surface before turning off the display. This allows the code to be verified and corrected if needed, ensuring display performance consistency even when the display is turned off to save energy on a continuous basis.
Solution Approach 2:
Instead of continuously monitoring or updating the display, the system performs periodic verification by capturing images of the displayed code at intervals. This periodic action ensures display performance consistency while allowing the display to remain off between updates, reducing energy consumption.

AI summary
Provided are a display method and a display device with which the display performance of a two-dimensional code can be improved in a display panel that can be used without damaging the texture of a space. When a display fault occurs in a display panel in which a thin layer, comprising a naturally-derived wood, a natural fiber, a natural leather, or a natural stone, or comprising a synthetic fiber, a synthetic leather, or a synthetic stone that is a raw material produced by imitating a natural appearance and feel, is provided on the peripheral surface of a housing so as to be in contact with the panel front surface, a two-dimensional code is corrected by being moved or rotated and is displayed.
