Solution Overview

Problem

Existing electronic devices with rollable displays experience discontinuous image rendering when the display area changes, leading to a non-smooth viewing experience due to inadequate adaptation of image representation with the changing display size.

Innovation Solution

The electronic device includes a processor that identifies events of display area extension or contraction and adjusts the image representation based on the direction and speed of the change, ensuring a seamless visual experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of moving object

If the display area is extended by sliding the housing, then the viewing area increases, but the image representation becomes discontinuous or awkward

Engineering Contradiction:
Improvedisplay areaVSAvoidviewing experience
Core Design Contradiction:
Area of moving objectVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the image representation adaptive and changeable in real-time according to the display area extension state. The processor dynamically adjusts image parameters (position, size, rotation angle, visual effects) based on the current extension distance and speed, transforming the static image display into a dynamic process that continuously adapts to the changing display area, thereby ensuring smooth visual transitions throughout the extension process.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by modifying multiple image parameters simultaneously - position coordinates, scaling dimensions, rotation angles, and visual effect intensities - in response to display area extension. These parameter adjustments are calculated based on the extension distance and speed, allowing the image to transform smoothly from its initial state to a state suitable for the expanded display area, resolving the discontinuity issue.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If the image is only resized based on display area change, then the implementation is simple, but the visual engagement and user experience are insufficient

Engineering Contradiction:
Improveimage processing complexityVSAvoidvisual engagement
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent segments the image processing into multiple independent parameter adjustments - position adjustment, size scaling, rotation transformation, and visual effect application. Each parameter can be independently calculated and adjusted based on the extension state, allowing for modular processing that enhances visual engagement while maintaining manageable system complexity through divided functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements multi-functionality by enabling the image processing system to perform multiple operations simultaneously - resizing, repositioning, rotating, and applying visual effects - all in response to a single trigger (display area extension). This universal approach allows the same processing framework to handle diverse visual transformation needs, enhancing adaptability without proportionally increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If the image representation changes during extension, then the user experience improves, but the processing requirements and computational load increase

Engineering Contradiction:
Improveuser experienceVSAvoidprocessing power
Core Design Contradiction:
Ease of operationVSPower

Solution Approach 1:

The patent applies partial action by selectively adjusting only the necessary image parameters based on the extension state, rather than completely regenerating or reprocessing the entire image. The processor calculates incremental changes in position, size, and rotation based on extension distance and speed, applying only the required transformations to maintain visual continuity, thereby reducing computational load while improving user experience.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

An electronic device according to an embodiment may comprise: a housing; a memory configured to store instructions; a display slidable into the housing or slidable out of the housing; and at least one processor, when the instructions are executed, configured to: identify, while an image is displayed in a display area of the display exposed outside the housing, an event in which the display area exposed outside the housing is extended; and change, in response to the identification, a representation of the image based on at least one of a direction in which the display area is extended or a speed at which the display area is extended, while the display area is extended.
