Solution Overview

Problem

Flexible displays in electronic devices experience relative displacement during folding or rolling operations, causing user discomfort and potential perception of defects, as the position of layers like the printed layer shifts relative to the light emitting layer, which can be visually noticeable.

Innovation Solution

An electronic device with a flexible display and a processor that identifies the folding angle and generates a virtual dead space area on the display, outputting it in a specified color to coincide with the displaced printed layer, thereby masking the displacement and enhancing user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a flexible display is folded or rolled, then portability and convenience of use are improved, but relative displacement between layers occurs causing visual defects and user discomfort

Engineering Contradiction:
ImproveportabilityVSAvoidlayer alignment
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent pre-calculates and stores the relationship between folding angles and layer displacements before the device is used. When folding occurs, the system retrieves pre-computed compensation values based on the current folding angle, enabling real-time correction without complex calculations during operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates a virtual copy of the displaced printed layer on the display screen. By rendering a compensating image that mirrors the expected displacement, the system overlays this virtual layer to counteract the actual physical displacement, making the layers appear aligned to the user.

Inventive Principle:
Principle #26Copying

2Strength

If layers in a flexible display are bonded together, then structural integrity is maintained, but relative displacement still occurs during folding causing visual discomfort

Engineering Contradiction:
Improvestructural integrityVSAvoidvisual discomfort
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent uses color or brightness changes in the displayed image to compensate for layer displacement. By adjusting the visual properties of the display content based on the folding angle and predicted displacement, the system creates a virtual offset that counteracts the physical misalignment, eliminating visual discomfort.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent introduces a software-based intermediary layer that processes the display output. This intermediary software layer calculates compensation based on folding angle sensors and modifies the displayed content accordingly, acting as a mediator between the physical displaced layers and the user's visual perception.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If the position of the printed layer is fixed relative to the light emitting layer, then alignment is maintained in flat state, but displacement becomes noticeable during folding operations

Engineering Contradiction:
Improvelayer alignmentVSAvoidfolding flexibility
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent transitions from a static alignment approach to a dynamic compensation approach. Instead of attempting to maintain fixed physical alignment, the system dynamically adjusts the displayed image position and orientation based on real-time folding angle detection, allowing the display to adapt to any folding state while maintaining visual alignment.

Inventive Principle:
Principle #15Dynamics

AI summary

An electronic device may include: a flexible display; and at least one processor. The at least one processor may be configured to: identify the folding angle of the electronic device; identify the displacement of a printed layer of the flexible display according to the identified folding angle; generate a virtual dead space region to substantially abut a portion of the boundary of the printed layer on the basis of the identified displacement; and output at least a portion of the generated virtual dead space region in a specified color on the flexible display.
