Bifacial Display Panels with Shared Illumination for Dual-Side Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional one-sided display devices obstruct the view of individuals seated on opposite sides of a desk, and implementing two separate display devices back-to-back increases physical footprint, power consumption, and compatibility issues.
Innovation Solution
A bifacial display device with two display panels oriented 180 degrees apart, sharing a common light source and image capture devices, allows simultaneous viewing from opposite sides with reduced power consumption and footprint, and adjusts images based on user gaze and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate display devices are implemented back-to-back to enable viewing from opposite sides, then viewing accessibility is improved, but physical footprint increases
Solution Approach 1:
The patent merges two separate display devices into a single integrated device by placing two display panels back-to-back within one housing structure. This allows the device to function as two independent displays while occupying the space of only one device, thereby improving viewing accessibility for multiple users without increasing the physical footprint on the desk surface.
2Adaptability or versatility
If two separate display devices are implemented back-to-back to enable viewing from opposite sides, then viewing accessibility is improved, but power consumption increases
Solution Approach 1:
The patent implements a shared light source that serves both display panels simultaneously, making the illumination system multi-functional. Instead of requiring two separate light sources for two independent devices, this single light source provides backlighting for both panels, thereby reducing overall power consumption while maintaining the ability to display content on both sides for multiple users.
3Adaptability or versatility
If two separate display devices are implemented back-to-back to enable viewing from opposite sides, then viewing accessibility is improved, but device compatibility issues increase
Solution Approach 1:
The patent combines two display panels, a shared light source, and control circuitry into a single integrated housing unit. This unified design ensures that both display panels are compatible with the same power supply, control system, and physical interface, eliminating the compatibility issues that would arise from connecting two separate display devices to different systems or interfaces.
