Curved Text Display Control for Mismatched Screen Aspect Ratios

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing input display control devices fail to generate display information for displaying an entire character string when a part of the string protrudes into a display region where information is not displayed, due to differing aspect ratios between terminals in mirroring displays.

Innovation Solution

An input display control device that sets a first virtual region around the display region and a second virtual region for adjusting aspect ratios, extending the curve to accommodate the protruding part of the character string in these regions to ensure complete display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If display information is generated for terminals with different aspect ratios, then complete character string display is achieved, but display region utilization becomes inefficient due to black belts or unused regions

Engineering Contradiction:

Improvecomplete character string displayVSAvoiddisplay region utilization

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The display region is segmented into two distinct virtual regions: a first virtual region for displaying character strings and a second virtual region for aspect ratio adjustment. This segmentation allows the system to handle different aspect ratios without creating black belts, as the second virtual region is intentionally left unused rather than filled with placeholder content.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a virtual dimension beyond the physical display boundaries. By setting virtual regions that extend beyond the actual display area, the system can accommodate character strings that would otherwise protrude from the display region, effectively adding a dimensional buffer for aspect ratio variations.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the display region is reduced to match the communication partner's aspect ratio, then aspect ratio compatibility is achieved, but the character string may protrude from the display region

Engineering Contradiction:

Improveaspect ratio compatibilityVSAvoidcomplete character string visibility

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary action by pre-defining virtual regions that extend beyond the display region before generating display information. This allows the character string to be positioned within the extended virtual region, ensuring complete visibility while maintaining aspect ratio compatibility through the second virtual region for adjustment.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The virtual regions act as intermediaries between the character string display and the physical display boundaries. The first virtual region accommodates the character string with sufficient buffer, while the second virtual region serves as an intermediary zone for aspect ratio adjustment without affecting the visible display content.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a second virtual region is set for aspect ratio adjustment, then aspect ratio matching with communication partners is enabled, but the curve length available for character string display is reduced

Engineering Contradiction:

Improveaspect ratio matchingVSAvoidcurve length for character string

Core Design Contradiction:

Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The patent applies local quality by differentiating the functional characteristics of different virtual regions. The first virtual region is optimized for character string display with sufficient curve length, while the second virtual region is dedicated solely to aspect ratio adjustment. This local differentiation ensures that the curve length available for character strings is maximized in the relevant region.

Inventive Principle:

Principle #3Local quality

AI summary

A display control unit sets a first virtual region around a display region of a display, sets, as a second virtual region, a region which is a part of the display region and which does not display information shared with a terminal of a communication partner in order to match an aspect ratio with that of the terminal of the communication partner, in a case where it is determined that a part of a character string protrudes from the display region, extends a curve to any one of the first virtual region, the second virtual region, and the first virtual region straddling the second virtual region, and generates display information in which the part of the character string is disposed along the extended curve in any one of the first virtual region, the second virtual region, and the first virtual region straddling the second virtual region.
