Solution Overview

Problem

Conventional flexible glass displays lack the ability to dynamically control image data portions based on deformation states and user input, such as bending or twisting, which limits interactive user experiences and tactile feedback.

Innovation Solution

A flexible glass display apparatus equipped with sensing units to detect deformation and touch input, and a controller that adjusts image data portions in real-time by changing colors, positions, and combining tactile information across different areas of the display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the flexible glass display is bent or deformed, then the display can be made flexible and portable, but image data portions displayed in different areas may overlap and become indistinguishable

Engineering Contradiction:
ImproveflexibilityVSAvoidimage distinguishability
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The controller changes the color of at least part of image data portions displayed in first and second areas to distinguish them when they overlap due to bending. Specifically, the controller changes the color to a mixture of the original color and a reference color, enabling users to distinguish between overlapping image portions even when the display is deformed.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The system dynamically adjusts image display parameters based on the deformation state of the flexible glass display. The controller continuously monitors bending through sensing units and real-time adjusts color and position of image data portions to maintain distinguishability throughout the deformation process.

Inventive Principle:
Principle #15Dynamics

2Area of stationary object

If the display area is increased to show more image data, then information display capacity is improved, but touch input detection accuracy decreases when areas overlap due to bending

Engineering Contradiction:
Improvedisplay areaVSAvoidtouch input detection accuracy
Core Design Contradiction:
Area of stationary objectVSMeasurement precision

Solution Approach 1:

The system applies different touch detection modes to different areas of the display based on their deformation state. When bending is detected, the controller identifies first and second areas that are brought into contact and applies appropriate detection sensitivity to each, maintaining accurate touch input detection despite area overlap.

Inventive Principle:
Principle #3Local quality

3Loss of information

If real-time color changing is implemented to maintain image distinguishability, then image clarity is improved, but energy consumption increases

Engineering Contradiction:
Improveimage distinguishabilityVSAvoidenergy consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The controller periodically monitors the deformation state through sensing units and only activates color changing when bending is detected. This periodic checking and conditional activation reduces energy consumption compared to continuous color adjustment, while maintaining image distinguishability when needed.

Inventive Principle:
Principle #19Periodic action

AI summary

A flexible glass display apparatus and a method for displaying image data in the apparatus are provided. The flexible glass display apparatus includes: a flexible glass display unit that displays image data portions; a sensing unit that detects bending of the display unit; another sensing unit that detects first and second areas which are brought into contact with each other due to bending of the display unit; and a controller, upon detection of contact between the first and second areas, controls at least one image data portion displayed in the first and second areas based on the contact, wherein an image data portion displayed in any one of the first and second areas is distinguishable in the other area.
