Flexible Display Touch Control State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible and touch-sensitive display devices are prone to accidental contact-induced malfunctions when the flexible display panel is handled, leading to unintended inputs and compromised user experience.
Innovation Solution
A flexible display device with a base, a flexible display panel, a detecting unit, and a control unit that determines the operating state of the panel, activating or deactivating touch control functions based on whether the panel is exposed or concealed, thereby minimizing accidental contacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the flexible display panel is made touch-sensitive to reduce the number of buttons and increase display size, then the device offers better portability and larger display area, but the device becomes prone to accidental contact-induced malfunctions when the panel is handled or received
Solution Approach 1:
The patent applies the dynamics principle by making the touch control unit's operational state dynamic rather than static. The touch control unit is activated only when the flexible display panel is in the extended state and deactivated when the panel is in the received state. This dynamic adjustment of functionality based on device state resolves the contradiction by enabling touch input only when accidentally contact is unlikely, while maintaining large display area when extended.
Solution Approach 2:
The patent applies parameter changes by modifying the operational parameter of the touch control unit (activated/deactivated state) based on the physical state of the flexible display panel. By changing the touch control unit's operational parameter in response to panel deployment status, the system achieves both large display area and reliable touch input accuracy.
2Ease of operation
If the touch control unit remains activated at all times to ensure responsive input, then the device offers continuous input capability, but power consumption increases and accidental contacts during panel handling cause malfunctions
Solution Approach 1:
The patent applies periodic action by intermittently activating the touch control unit based on the operational state of the flexible display panel. Instead of continuous activation, the touch control unit is periodically enabled when the panel is extended and disabled when received, reducing power consumption while maintaining responsiveness during actual use.
Solution Approach 2:
The system dynamically adjusts the touch control unit's operational state based on panel deployment, achieving optimal balance between responsiveness and power consumption by activating touch functionality only when needed.
3Weight of moving object
If the flexible display panel is made foldable or retractable to enhance portability, then the device becomes more portable, but the panel may contact other objects during handling, generating unintended contact-based inputs
Solution Approach 1:
The patent applies preliminary anti-action by preemptively deactivating the touch control unit when the flexible display panel is in the received state, before accidental contact can occur. This preventive measure eliminates the harmful effect of accidental contact by ensuring the touch control unit is not responsive during handling operations.
Solution Approach 2:
The system takes preliminary action by detecting the panel's operational state and adjusting touch control unit activation accordingly. The touch control unit is activated only after the panel is fully extended and positioned for use, preventing accidental inputs during the handling and deployment process.

AI summary
A flexible display device includes a base, a flexible display panel, a detecting unit and a control unit. The flexible display includes a touch control unit that could be exposed outside of or received within the base. The detecting unit is used to detect the operating state of the flexible display panel. Then, the control unit controls the touch control unit according to a detected result of the detecting unit. Accordingly, the flexible display device according to the present invention may effectively reduce the accidental contact-induced malfunctions.
