Flexible Display Sliding Control for Misoperation Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with flexible displays, such as rollable displays, can experience misoperations or damage when the display is inadvertently expanded or reduced while the device is in specific states or situations, like making a call or being charged.
Innovation Solution
An electronic device with a flexible display that includes a first housing, a second housing slidably coupled to the first housing, and a processor that controls the sliding motion based on input and designated conditions, such as disabling sliding when the device is making a call or being charged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the flexible display is made expandable by sliding the second housing, then the display area is increased, but the risk of misoperation or damage increases when the device is in specific states
Solution Approach 1:
The patent implements dynamic control of the sliding mechanism based on device state. The processor determines whether to enable or disable sliding operations according to current device conditions (e.g., charging state, call state). When the device is in a charging state or receiving call, the sliding operation is disabled to prevent misoperation. This dynamic adaptation allows the display area to be expanded when safe, while preventing damage when the device is in vulnerable states.
2Ease of operation
If sliding control is always enabled, then the ease of operation is improved, but the risk of damage during charging or calling increases
Solution Approach 1:
The patent employs feedback mechanisms where the processor continuously monitors device state (charging status, call status) and adjusts sliding control accordingly. When the device enters a charging state or receives a call, the system provides feedback by disabling the sliding function. This feedback loop ensures that sliding control remains convenient when appropriate while automatically preventing damage when harmful conditions are detected.
3Adaptability or versatility
If the second housing is made slidable relative to the first housing, then the adaptability of the display is improved, but the device complexity increases
Solution Approach 1:
The patent implements a nested housing structure where the second housing is slidably coupled to the first housing. The second housing contains the flexible display and can be inserted into or ejected from the first housing. This nesting approach allows the display to adapt between expanded and compact states while using a relatively simple mechanical coupling mechanism, thus achieving high adaptability with controlled complexity.

AI summary
An electronic device according to various embodiments of the disclosure may include a first housing, a second housing slidably coupled to the first housing, a flexible display having a visually exposed display region that is reduced or expanded based on sliding in or sliding out of the second housing, an input unit configured to receive an input, a processor, and memory storing instructions that, when executed by the processor, cause the electronic device to: identify whether a condition of the electronic device for disabling sliding in or sliding out of the second housing is satisfied, receive an input via the input unit, operate in a first mode in which slide-in or slide-out of the second housing is controlled based on the input and the condition not being satisfied, operate in the first mode in which slide-in or slide-out of the second housing is disabled based on the condition being satisfied, and operate in a second mode in which the slide-in or slide-out of the second housing is disabled regardless of the condition being satisfied or not.
