Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile electronic devices lack the capability to offer a wide range of variations for presentation using displays, particularly in terms of switching between transmissive and reflective states to enhance user experience and reduce power consumption.
Innovation Solution
A mobile electronic device with a first display and a second display that can switch between transmissive and reflective states, where the second display is overlapped with the first display and includes separate areas for presentation, allowing for the control of display states to extend across the first and second display areas, thereby offering varied display options while improving power efficiency and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single display is used, then the device structure is simple, but the presentation variations are limited
Solution Approach 1:
The display system is segmented into a first display and a second display that can be independently controlled. The second display is divided into a first area overlapping with the first display and a second area not overlapping with it, allowing different presentation modes in different regions.
Solution Approach 2:
The second display is configured to dynamically switch between a transmissive state and a reflective state, enabling the display to adapt its presentation characteristics based on usage conditions, ambient light, and user preferences.
2Illumination intensity
If the second display is always in transmissive state, then visibility is good, but power consumption increases
Solution Approach 1:
The second display dynamically switches between transmissive and reflective states based on ambient light conditions and usage scenarios, optimizing the balance between visibility and power consumption in real-time.
Solution Approach 2:
The display mode parameter is changed between transmissive and reflective states to adapt to different environmental conditions, allowing the system to maintain adequate visibility while minimizing energy consumption when appropriate.
