Flexible Display Size Control via Proximity Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with flexible displays face issues with size change errors and user inconvenience due to the exposure and hiding of display regions during size adjustments, leading to potential finger entrapment between fixed and moving parts.
Innovation Solution
An electronic apparatus with a flexible display that includes a sensor to detect object approaches, allowing the controller to adjust the display size based on measurement information, ensuring safe and convenient operation by preventing size changes when objects, like fingers, are detected in the path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display size is increased to provide a larger screen for professional tasks, then the display area is improved, but the portability deteriorates
Solution Approach 1:
The display size is made dynamically adjustable rather than fixed. The display can be extended to a first size for professional tasks requiring large screen area, and folded to a second size for portability. This dynamic transformation allows the same display structure to serve both contradictory requirements at different operational states.
2Adaptability or versatility
If the display size is changed to accommodate different usage scenarios, then the adaptability is improved, but the risk of finger entrapment and user inconvenience worsens
Solution Approach 1:
Before the display size change is executed, the system performs preliminary detection to identify whether a finger or object is present in the potential entrapment zone between the display and housing. Based on this preliminary detection result, the display size change is either prevented or adjusted, thereby avoiding finger entrapment before it can occur.
Solution Approach 2:
The system continuously monitors the space between the display and housing using a sensor during the display size change process. When the sensor detects a finger or object in this space, it provides feedback to the controller, which then adjusts or prevents the display size change to avoid entrapment. This closed-loop feedback mechanism ensures user safety during dynamic display adjustment.
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
The solution effectively prevents size change errors and user inconvenience by dynamically adjusting the display size based on object proximity, ensuring safe operation and preventing finger entrapment between moving parts.

AI summary
Provided is an electronic apparatus including a flexible display comprising at least a portion disposed at a first surface, a body frame disposed at a second surface opposed to the first surface, a display frame moving to decrease a distance to a first region of the body frame in response to a reduction in size of the flexible display exposed on the first surface, a first sensor disposed at at least a portion of the first region of the body frame and configured to sense an approach of an object, and a controller configured to control the size of the flexible display exposed on the first surface based on measurement information of the first sensor. The first region includes a surface corresponding to a position of the display frame among at least one surface of the body frame.
