Display Control for Enlarged Character Dot Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with small screen sizes and resolutions face challenges in providing an enlarged display of characters without impairing the visual comprehensibility of the entire screen, often requiring blank areas or overlapping characters, which can lead to reduced clarity.
Innovation Solution
A display device with an operation portion, display portion, and display control portion that displays characters as dot patterns, using a predetermined display size and switching to alternate characters when a special character is designated, allowing for adjustable display sizes and improved visual clarity by using alternate characters when space is limited.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an enlarged display is implemented in a separate window, then the visual comprehensibility of the designated character is improved, but the visual comprehensibility of the entire screen is impaired due to other characters being concealed
Solution Approach 1:
The patent merges the enlarged character display with the original screen content by displaying both the enlarged character and the remaining characters within the same display area. This is achieved by calculating the display position based on the character's position in the character string and the number of display lines, allowing the enlarged character to be shown without completely obscuring other content.
Solution Approach 2:
The patent applies local quality by displaying the designated character with enhanced visual properties (enlarged size, multiple display lines) only at its specific location, while other characters maintain their normal display properties. This localized enhancement improves the visibility of the designated character without compromising the overall screen information density.
2Measurement precision
If an enlarged display is implemented in the same window, then the visual comprehensibility of the designated character is improved, but blank areas or overlapping characters are required which impairs overall screen clarity
Solution Approach 1:
The patent employs dynamics by adjusting the display parameters (number of display lines, display position) based on the character's position in the character string and the total number of display lines. This dynamic adjustment allows the enlarged character to be displayed without creating fixed blank areas or requiring static layout changes that would complicate the screen structure.
Solution Approach 2:
The patent changes display parameters (specifically the number of display lines and display position coordinates) based on the character's position and the overall screen configuration. By dynamically adjusting these parameters, the system can display enlarged characters without creating unnecessary blank areas or overlapping issues, thus avoiding increased device complexity.
3Measurement precision
If the display size is increased for a designated character, then the visual comprehensibility of that character is improved, but the available display area for other characters is reduced
Solution Approach 1:
The patent utilizes another dimension by extending the character display into multiple display lines vertically while maintaining the same horizontal display area. This dimensional extension allows the designated character to be displayed in an enlarged format across multiple lines without reducing the horizontal space available for other characters, thus preserving the overall display area.
Solution Approach 2:
The patent segments the display area by allocating specific display lines to the enlarged character based on its position in the character string. This segmentation allows the enlarged character to occupy only the necessary vertical space while leaving other display areas available for surrounding characters, thereby maintaining optimal use of the total display area.

AI summary
A display device includes an operation portion, a display portion, a character designating portion, and a display control portion. The display control portion displays the at least one character on the display portion. The display control portion displays, in a case where the at least one character displayed on the display portion includes a predetermined special character and the number of at least one display lines is not less than a threshold value, a dot pattern for an alternate character instead of a dot pattern for the special character. The display control portion changes, in a case where a designated character is the alternate character, the dot pattern for the designated character displayed on the display portion to the dot pattern for the special character.
