Flexible Screen Area Selection via Rotation Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen-on methods for electronic apparatuses do not effectively protect user privacy, as they do not differentiate between intended and unintended screen areas when lighting up the screen.
Innovation Solution
A screen-on method that divides a flexible or combined screen into at least two areas using a bending axis, where the electronic apparatus determines the first screen area to light up based on rotation speeds or accelerations around the bending axis, and keeps the second area in a screen-off state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the entire screen is lighted up when a screen-on instruction is received, then the user can view content on any screen area, but user privacy is compromised and energy consumption increases
Solution Approach 1:
The screen is divided into multiple screen areas (first screen area and second screen area) with the bending axis as the division boundary. When a screen-on instruction is received, only the first screen area is lighted up while the second screen area remains dark, allowing selective display control to protect privacy while reducing energy consumption.
2Use of energy by moving object
If the electronic apparatus uses rotation speeds or accelerations to determine which screen area to light up, then privacy is protected and energy is saved, but the device complexity increases
Solution Approach 1:
The electronic apparatus uses its own motion characteristics (rotation speeds or accelerations) to automatically determine which screen area should be lighted up. The device self-identifies the intended screen area based on its rotation state, eliminating the need for additional complex detection mechanisms or user input.
3Loss of energy
If the electronic apparatus divides the screen into multiple areas and selectively lights them up, then privacy is protected and energy is saved, but the manufacturing precision requirements increase
Solution Approach 1:
The screen is pre-divided into multiple screen areas with the bending axis serving as the division boundary during the design and manufacturing phase. This preliminary segmentation allows the device to selectively light up only the necessary screen area during operation, reducing energy waste while the bending axis alignment ensures consistent and accurate area division.
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
This method ensures that only the intended screen area is lit up, protecting user privacy and potentially saving energy by limiting the areas that are actively displayed.
Implementation Method 1
the electronic apparatus may determine a first screen area based on rotation speeds or rotation accelerations at which the at least two screen areas rotate around the bending axis
