Retractable Display Screen Stretching for Content Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with retractable display screens face issues when additional content needs to be displayed, as current methods often superimpose new content onto the existing display, leading to blocking and poor user experience.
Innovation Solution
A device control method that determines additional display content and controls the retractable display screen to stretch, adding a new display region beyond the current one, allowing the new content to be displayed without blocking the original content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If additional content is displayed by superimposing on current content, then display efficiency is improved, but original content becomes blocked and visibility deteriorates
Solution Approach 1:
The patent transitions from two-dimensional content superposition to three-dimensional spatial expansion by extending the display screen physically. When additional content needs to be displayed, the screen extends outward to create a new display region, allowing both original and additional content to be visible simultaneously without blocking, thus resolving the contradiction between display efficiency and original content visibility.
2Loss of information
If display screen is extended to show additional content, then content visibility is improved, but device complexity increases
Solution Approach 1:
The display screen is designed with dynamic extendability, transitioning from a static display to a dynamically adjustable one. The screen can extend when additional content needs to be displayed and retract when not needed, allowing the device to adapt its display capabilities to actual usage requirements while minimizing complexity during normal operation.
Solution Approach 2:
The retractable display mechanism serves multiple functions: it acts as a normal display screen during standard operation and transforms into an extended display when additional content needs to be shown. This multi-functionality allows a single mechanism to handle both regular display tasks and expanded content display without requiring separate dedicated components.

AI summary
Provided is a device control method, which is applied in an electronic device. The electronic device includes a retractable display screen. The method includes: determining a second display content to be displayed in addition to a first display content currently displayed; controlling, based on the second display content, the retractable display screen to stretch, for adding a display region beyond a current display region used for displaying the first display content; and displaying the second display content in the added display region, and continuing displaying the first display content in the current display region.
