Flexible Display Extension Control for Compact Larger Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face limitations in increasing display size while maintaining portability, as traditional mechanical keypads are removed for touch screens, leading to constraints in expanding the display area without compromising device size and weight.
Innovation Solution
An electronic device with a flexible display that is extendable or retractable, featuring a first and second housing with a movable connection, a motor-driven mechanism, and a drive circuit to control the movement of the flexible display, allowing it to be partially retracted or extended based on trigger signals and motor operation parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a larger display is mounted on the electronic device, then the screen area is increased, but the device size and weight increase, compromising portability
Solution Approach 1:
The display is divided into a first display area mounted on the first housing and a second display area mounted on the second housing. The second housing can move relative to the first housing, allowing the second display area to be extended or retracted. This segmentation enables the display area to be increased when needed while maintaining a compact form when the second housing is retracted, thus resolving the contradiction between large display area and portable size.
Solution Approach 2:
The second housing is configured to be movable relative to the first housing along a movement direction, transitioning between a first position (extended) and a second position (retracted). This dynamic configuration allows the display area to change based on user needs, providing a large screen when extended and a compact form when retracted, thereby resolving the contradiction between display size and portability.
2Area of stationary object
If a larger display is mounted on the electronic device, then the screen area is increased, but the device size increases, compromising portability
Solution Approach 1:
The display is segmented into two areas on separate housings, allowing the second display area to be extended along the movement direction when needed and retracted to maintain a compact overall length. This resolves the contradiction between large display area and compact device length.
Solution Approach 2:
The movable second housing allows the display area to dynamically extend along the length direction when needed, while retracting to maintain a compact form. This dynamic adjustment resolves the contradiction between displaying large area and maintaining short device length for portability.
3Length of moving object
If a flexible display is made considerably thin, then portability is improved, but stable operation becomes difficult to implement
Solution Approach 1:
The thin flexible display is mounted on a movable housing that can transition between extended and retracted positions. When retracted, the display is protected within the housing structure, providing stability. When extended, the display can be used. This dynamic configuration allows a thin display to maintain both portability and operational stability.
Solution Approach 2:
The thin flexible display is nested within the housing structure when retracted, protected by the housing boundaries. This nesting provides physical support and stability to the thin display, preventing damage while maintaining its thin profile for portability.

AI summary
An electronic device is provided. The electronic device includes memory for storing instructions, a first housing, a second housing, disposed to be movable in a first direction or a second direction with respect to the first housing, and overlapping at least a portion of the first housing, a flexible display, at least partially mounted on the surface of the second housing, and having at least a portion of an area exposed to an outside retracted or extended based on movement of the second housing, a motor configured to drive the second housing to move in the first direction or the second direction, a drive circuit configured to control the driving of the motor, and at least one processor. The instructions, when executed by the at least one processor individually or collectively, cause the electronic device to, based on receiving a trigger signal related to retraction or extension of the flexible display, transmit, to the drive circuit, a motor driving signal for driving the motor, based on a rotation speed and an operation time of the motor in an active state of the motor based on the motor drive signal, calculate a movement distance of the second housing or the flexible display, and based on obtaining a signal related to a position of the second housing or the flexible display, initialize the calculated movement distance.
