Geo-Fenced E-Ink Vehicle Display for Privacy-Safe Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle information display methods using vehicle registration cards expose private information and pose safety concerns due to light reflection, leading to privacy leaks and potential hazards while driving.
Innovation Solution
A vehicle information display apparatus with an E-ink display panel that displays vehicle information, such as license details and a pseudo mobile phone number, only when within a predetermined geographic range, using GPS to determine location and integrating with a server to generate a pseudo number, reducing privacy risks and minimizing light reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vehicle registration card with printed information is used for identity verification, then information can be displayed and verified, but private information is exposed and light reflection causes safety hazards
Solution Approach 1:
The patent changes the display medium from traditional reflective materials to E-ink display panel, which uses electro-optical effects rather than light reflection. The E-ink display changes its optical properties by applying voltage to move particles, allowing information display without reflective hazards while maintaining visibility
Solution Approach 2:
The patent introduces an E-ink display panel as an intermediary between the vehicle registration information and the viewer. This intermediary displays information electronically rather than through printed text that reflects light, eliminating the safety hazard while preserving information verification functionality
2Ease of operation
If vehicle information is displayed continuously, then information is always available for verification, but privacy risk increases in unauthorized areas
Solution Approach 1:
The patent makes the display dynamic by controlling it to activate only when the vehicle enters a predefined geographic range. The display transitions from static continuous display to dynamic conditional display, ensuring information is available when needed for verification while remaining hidden in unauthorized areas to protect privacy
Solution Approach 2:
The system uses GPS location feedback to control display activation. The display panel driving circuit receives signals from the processor based on geographic position feedback, automatically activating or deactivating the display according to whether the vehicle is within the authorized verification range
3Reliability
If E-ink display panel is kept connected to power source, then display can be refreshed and updated, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by connecting the E-ink display panel to the power source only when needed for display updates (when vehicle enters geographic range), rather than maintaining continuous connection. The display is activated periodically based on location triggers, reducing overall energy consumption while maintaining update capability when required
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures privacy protection by limiting information display to specific geographic areas, reducing light reflection, and maintaining communication integrity by using a pseudo number, thus enhancing safety and security.

AI summary
A vehicle-mounted display apparatus includes a display panel, a geographic position acquisition circuit, a processor, and a display panel driving circuit. The geographic position acquisition circuit acquires a current geographic position of a vehicle. The processor determines whether the current geographic position of the vehicle is within a stored geographic range, and if so, generates a first control signal. The display panel driving circuit controls the display panel to display the vehicle information upon receiving the first control signal from the processor. The vehicle information includes at least one of vehicle license information and a pseudo mobile phone number. In the display apparatus, an information push terminal communicating circuit communicates with an information push terminal to obtain the vehicle information and the stored geographic range, and a server communicating circuit communicates with a server to obtain the pseudo mobile phone number corresponding to an identification for the display apparatus.
