Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-sided displays with touch functions have not been applied in the medical field due to concerns of personal information leakage and potential disease transmission through frequent user contact.
Innovation Solution
A dual-sided display design incorporating a peep-proof element between the light guide plate and the second display panel, along with antibacterial films on the cover plates, to reduce information leakage and prevent disease transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dual-sided display with touch functions is used, then the functionality and user interaction are improved, but the risk of information leakage and disease transmission increases
Solution Approach 1:
The display is divided into two independent sides with separate display panels (first display panel and second display panel), each capable of independent operation. This segmentation allows different information to be displayed on each side, reducing information leakage risk while maintaining full display functionality on both surfaces.
Solution Approach 2:
A peep-proof element is introduced as an intermediary component between the light guide plate and the second display panel. This element mediates the light transmission to prevent peeping from the side, thereby eliminating information leakage risk while preserving the dual-sided display functionality.
2Adaptability or versatility
If a dual-sided display with touch functions is used, then the functionality and user interaction are improved, but the risk of disease transmission increases
Solution Approach 1:
Antibacterial films are applied to the cover plates of the display. These films provide a protective barrier that prevents disease transmission through frequent contact, while being cost-effective and easily replaceable if needed, thus maintaining display functionality without compromising health safety.
3Object-affected harmful factors
If a peep-proof element is added to the backlight module, then information leakage is reduced, but the device complexity increases
Solution Approach 1:
The peep-proof element is merged with the existing backlight module structure, specifically positioned between the light guide plate and the second display panel. This integration approach prevents information leakage while minimizing additional structural complexity by utilizing the existing optical path components.

AI summary
A dual-sided display having a first surface and a second surface opposite to the first surface is provided. The dual-sided display includes a first display panel, a second display panel, and a backlight module. The first display panel is used to display an image on the first surface. The second display panel is used to display an image on the second surface. The backlight module is disposed between the first display panel and the second display panel to provide light sources for the first display panel and the second display panel. The backlight module includes a light guide plate, a light emitting element, and a peep-proof element. The light emitting element is used to provide the light sources and is disposed adj acent to one side of the light guide plate. The peep-proof element is disposed between the light guide plate and the second display panel.
