Dual-Mode Display Switching Between Transparent and Active States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic displays lack the ability to efficiently switch between dynamic and semi-static modes while maintaining low power consumption and high transparency, which limits their versatility and energy efficiency.
Innovation Solution
A dual-mode display device comprising a first display with pixels that can modulate, absorb, or reflect visible light in one mode and become substantially transparent in another, paired with a second display that can emit, modulate, absorb, or reflect visible light, utilizing a segmented backlight for illumination, allowing for dynamic and semi-static modes of operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a display operates in dynamic mode with full functionality, then high resolution and color reproduction are achieved, but power consumption increases
Solution Approach 1:
The display device dynamically switches between two operational modes: a first mode where the first display is active for high-resolution dynamic content, and a second mode where the first display becomes transparent and only the second display operates for static content. This dynamic mode switching allows the system to optimize power consumption based on content requirements while maintaining high resolution when needed.
Solution Approach 2:
The display system is segmented into two independent display units (first display and second display) that can operate independently or in combination. The first display handles dynamic, high-resolution content while the second display handles static content, allowing the system to segment power consumption based on content type and reduce overall energy usage when full functionality is not required.
2Adaptability or versatility
If a display uses multiple display layers to enable dual-mode operation, then versatility and energy efficiency are improved, but device complexity increases
Solution Approach 1:
The patent combines a first display and a second display into a single integrated display device with shared control logic and segmented backlighting. The displays are positioned in overlapping relationships (either the first display in front of or behind the second display) and controlled by a unified controller that manages mode switching, thereby reducing overall system complexity compared to separate display systems while maintaining dual-mode versatility.
Solution Approach 2:
The display device achieves multi-functionality by enabling the first display to operate in two distinct modes: an active display mode for high-resolution dynamic content and a transparent mode for static content displayed on the second display. The segmented backlight and unified controller provide universal support for both modes, allowing a single device structure to fulfill multiple display requirements without requiring separate specialized systems.
3Use of energy by moving object
If the first display pixels are made transparent to enable the second mode, then power consumption is reduced, but control precision over light modulation is limited
Solution Approach 1:
The first display pixels dynamically transition between two states: an active state where they modulate, absorb, or reflect visible light for high-resolution display, and a transparent state where they allow light to pass through for the second display mode. This dynamic state switching is controlled by the segmented backlight and control logic, enabling precise control over when light modulation is needed versus when transparency is required, thereby resolving the contradiction between power consumption and control precision.
