Solution Overview

Problem

Flexible display apparatuses face challenges in distinguishing between intentional and unintentional inputs, leading to unnecessary processing of unintended deformations, which affects user interaction and device functionality.

Innovation Solution

Incorporating a controller that selectively executes touch or bend manipulation modes based on user selection, using a combination of touch and bending sensors to determine intended inputs by analyzing properties such as location, pressure, and usage history, and deactivating sensors accordingly to prevent unintended operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If various input methods using different deformation gestures are applied to flexible display apparatus, then the functionality and user interaction capabilities are improved, but the ability to distinguish between intended and unintended inputs deteriorates, leading to unnecessary processing of unintended deformations

Engineering Contradiction:
Improveinput method versatilityVSAvoidinput detection accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent divides the input detection system into separate sensor modules: touch sensors for detecting touch inputs and bending sensors for detecting deformation inputs. This segmentation allows each sensor type to independently detect its specific input modality, preventing cross-interference and improving the accuracy of distinguishing between intended and unintended inputs while maintaining multiple input methods

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic sensor activation where the controller selectively activates or deactivates specific sensors based on the current operational context and detected input patterns. This dynamic approach allows the system to adapt to different usage scenarios, improving reliability by focusing detection resources on relevant input types while maintaining versatility through context-dependent sensor selection

Inventive Principle:
Principle #15Dynamics

2Productivity

If the flexible display apparatus processes all detected deformations as intended inputs, then no input is lost, but unnecessary operations are executed reducing system efficiency and user experience

Engineering Contradiction:
Improveinput processing efficiencyVSAvoiduser interaction quality
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent implements preliminary analysis of detected inputs by the controller, which evaluates sensor data against predefined criteria and patterns before executing operations. This preliminary action filters out unintended inputs (such as accidental bends during carrying) before they trigger operations, improving processing efficiency by avoiding unnecessary operations while maintaining ease of operation for legitimate user inputs

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent employs feedback mechanisms where the controller analyzes the characteristics of detected inputs (such as bending magnitude, duration, and pattern) and uses this information to determine whether to execute the corresponding operation. This feedback-based decision-making improves productivity by filtering out spurious inputs while maintaining high ease of operation for genuine user intentions through context-aware processing

Inventive Principle:
Principle #23Feedback

AI summary

A flexible display device is provided. The flexible display device includes a display which is bendable, a sensor arranged to sense a user manipulation of the display and a controller. The controller is arranged, if a user manipulation is sensed by the sensor, to determine whether the user manipulation is intended by the user and arranged, if it is determined that the user manipulation is intended by the user, to perform an operation corresponding to the user manipulation. The user manipulation comprises at least one of a touch on the display and a bend of the display.
