Solution Overview

Problem

In flexible-type electronic devices with variable screen sizes, touch sensitivity adjustments are needed to prevent erroneous operations during screen size changes, and existing methods either disable the touch panel, causing missed inputs or enable it, leading to unintended actions.

Innovation Solution

An electronic device with a flexible display that adjusts touch sensitivity based on detected screen size changes, lowering sensitivity during transitions and returning to original levels when stable, and differentiates sensitivity across display areas based on touch likelihood.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the touch panel sensitivity is set to a high level, then touch input recognition is improved, but erroneous operations occur during screen size adjustment

Engineering Contradiction:

Improvetouch input recognitionVSAvoidoperation accuracy

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The touch panel sensitivity is dynamically adjusted based on the screen size state. During screen size adjustment transitions, sensitivity is temporarily reduced to prevent erroneous touch inputs, while maintaining high sensitivity during stable states for accurate touch recognition. This dynamic adaptation resolves the contradiction between touch recognition accuracy and operation reliability during transitions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The sensitivity parameter of the touch panel is changed according to different operational states. When screen size adjustment is detected, the sensitivity parameter is modified to a lower value, and restored to the original value when adjustment completes. This parameter change strategy ensures reliable operation during transitions while maintaining precise touch input recognition during stable states.

2Reliability

If the touch panel is disabled during screen size adjustment, then erroneous operations are prevented, but user touch input is not recognized

Engineering Contradiction:

Improveoperation accuracyVSAvoidtouch input recognition

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Instead of completely disabling the touch panel, the sensitivity parameter is adjusted to a lower value during screen size adjustment. This allows the touch panel to remain operational and recognize user inputs while reducing the likelihood of erroneous operations, thus maintaining ease of operation while ensuring reliability.

3Ease of operation

If the touch panel remains enabled during screen size adjustment, then user touch input is recognized, but unintended operations occur

Engineering Contradiction:

Improvetouch input recognitionVSAvoidoperation accuracy

Core Design Contradiction:

4Adaptability or versatility

If the screen size is made variable, then display flexibility is improved, but layout configuration complexity increases

Engineering Contradiction:

Improvescreen shape variabilityVSAvoidlayout configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The layout configuration is automatically adjusted based on screen size parameters. When the screen size changes, the system modifies layout parameters such as window size, icon arrangement, and element positioning to adapt to the new screen dimensions. This automated parameter adaptation reduces the complexity of manual layout configuration while maintaining versatility.

AI summary

An electronic device includes a memory, a touch panel, a display having a flexible structure, at least one sensor, and at least one processor, and the memory stores instructions that cause, when executed, the at least one processor to during a driving section in which a changing in the screen size of the display is detected by the at least one sensor, adjust a touch sensitivity of the touch panel from a first setting value to a second setting value, and to, based on determining that the changing of the screen size of the display is detected to be finished by a sensing result of the at least one sensor, adjust the touch sensitivity of the touch panel from the second setting value to the first setting value.
