Flexible Display Device Segmentation for Stable Touch Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display devices with sliding or folding mechanisms suffer from user distraction and difficulty in performing touch inputs when the screen is extended, as the image and touch sensor movement disrupts the user's concentration and functionality.
Innovation Solution
A flexible display device design featuring a first and second body with a support, where the flexible display remains stable when one body is held, allowing for continuous image viewing and touch input without relative movement, and includes a filter to prevent foreign matter entry, with covers that overlap to maintain a fixed state and facilitate easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flexible display is modified by movement of a sliding member while the user holds the terminal body, then the display area can be changed, but the image moves while being displayed which deteriorates user concentration and recognition
Solution Approach 1:
The display device is divided into two separate bodies (first body and second body) that can move relative to each other. The flexible display is positioned such that one end is fixed to the first body while the other end connects to the second body. This segmentation allows the second body to slide relative to the first body, changing the effective display area, while the portion of the display on the first body remains stationary and maintains stable image display for user concentration.
2Adaptability or versatility
If the flexible display is modified by movement of a sliding member while the user holds the terminal body, then the screen can be extended, but it becomes impossible or very difficult to perform touch input while the flexible display is being modified
Solution Approach 1:
The display system is segmented into a stationary first body and a movable second body. The flexible display spans both bodies, allowing the second body to slide and extend the screen while the first body with its integrated touch sensor remains stable. This enables touch input to be performed on the stationary portion of the display during screen extension, maintaining ease of operation.
3Adaptability or versatility
If the flexible display is modified by moving two bodies relative to each other, then the display size can be variable, but the device complexity increases
Solution Approach 1:
The device is segmented into two bodies that move relative to each other along a sliding path. This segmentation provides variable display size capability while keeping each body structurally simple. The flexible display itself handles the complexity of connecting and moving between the two bodies, rather than requiring complex mechanical structures within each body.
Solution Approach 2:
The device employs dynamic relative movement between the two bodies instead of static fixed structures. The second body can slide along the first body to change display configuration, providing adaptability without requiring complex adjustable mechanisms. This dynamic approach simplifies the overall structure compared to static adjustable designs.

AI summary
A flexible display device is disclosed. The flexible display device includes a first body, a second body, a flexible display, and a first cover. The second body performs reciprocating movement between a first position and a second position relative to the first body. The flexible display includes a first region, a first connected region, and a second connected region. When the second body is at the first position, the first cover covers the second connected region and forms a rear surface of the flexible display device. When switching between the first position and the second position is made, the user may hold the flexible display device in contact with the first region and the first cover.
