Settlement Terminal Transmissive Display Panel Code Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing settlement terminals require customers to search for and align different reading positions for contactless IC credit, electronic money, and code symbol settlements, leading to inconvenience and interruption during the code settlement process.
Innovation Solution
A settlement terminal with a display panel that can be set to a transmissive state in at least a partial area, allowing the imaging unit located at the reverse side of the display panel to read code symbols held over and toward the display panel through this transmissive area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the imaging unit is located at an end of the settlement terminal for code symbol reading, then code settlement function is provided, but the customer is interrupted by searching for the reading position and suffers inconvenience
Solution Approach 1:
The patent merges the code symbol reading function with the display panel by positioning the imaging unit behind the display panel. This allows the code settlement function to be integrated into the same operational area as contactless IC and electronic money settlements, eliminating the need for customers to search for separate reading positions and improving ease of operation.
Solution Approach 2:
The patent moves the imaging unit from a traditional side-position to a behind-panel position, utilizing the depth dimension of the terminal structure. This dimensional repositioning allows the code reading function to share the same front-facing operational surface with other settlement functions, resolving the contradiction between functionality and ease of use.
2Loss of information
If the display panel is used for displaying information, then information display function is provided, but the imaging unit cannot read code symbols through it
Solution Approach 1:
The patent makes the display panel dynamically switchable between display mode and transmissive mode. When code reading is required, the panel becomes transparent to allow the imaging unit to capture code symbols; when information display is needed, it switches to opaque display mode. This dynamic property resolves the contradiction between information display and code reading reliability.
Solution Approach 2:
The patent changes the optical parameter (transparency) of the display panel based on operational requirements. By controlling the panel's transmissive state, the system can switch between displaying information and allowing code symbol imaging, thereby maintaining both information display capability and code reading reliability.
