Solution Overview

Problem

Existing character string display technologies face complexity and higher costs due to the need for controlling gradation, shading, or color hue, which complicates the effective use of display space and legibility.

Innovation Solution

A character string display device with a two-dimensionally arrayed display element unit and a controller that displays character patterns without blank lines by selectively turning off display elements when adjacent, allowing for efficient use of space and improved legibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If blank lines are provided between consecutive character patterns, then legibility of the character string is improved, but display space is consumed

Engineering Contradiction:

ImprovelegibilityVSAvoiddisplay space

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The invention extracts and removes the blank line elements from the display, allowing character patterns to be displayed in contact without consuming additional display space, while maintaining legibility through alternative means

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the parameter of character pattern display from separated (with blank lines) to contact display, and adjusts the display elements' properties (turning off specific elements) to maintain visual distinction and legibility

Inventive Principle:

Principle #35Parameter changes

2Reliability

If gradation, shading, or color hue is varied to enhance legibility without blank lines, then legibility is improved, but device complexity and cost increase

Engineering Contradiction:

ImprovelegibilityVSAvoidcontrol mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The invention segments the character pattern display into individual display elements, selectively turning off specific elements at contact boundaries between consecutive character patterns to create visual separation without requiring complex gradation or shading control mechanisms

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention uses simple on/off control of basic display elements instead of expensive and complex gradation, shading, or color hue control mechanisms, achieving legibility enhancement through a simpler, lower-cost approach

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

There is provided a character string display device including a character string display unit (10) including a plurality of display elements (110) arrayed two-dimensionally, and a display controller (20) configured to cause the character string display unit (10) to display a predetermined character string pattern by controlling display states of the plurality of display elements (110). In the character string display device, the display controller (20) is configured to cause the character string display unit (10) to display the character string pattern such that there is no blank line between consecutive character patterns of the character string pattern and that, when two display elements corresponding to the respective consecutive character patterns are adjacent to each other, a character pattern part corresponding to one of the adjacent display elements (110) is not displayed. The character string display device and a character string display method are simple and low cost, allow effective use of display space, and achieve higher legibility of a character string.
