Screen Magnification via DPI and DIP Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with limited vision face difficulties in reading small text on mobile devices due to their small screen size, as existing methods for adjusting font size do not significantly improve readability across different applications.
Innovation Solution
A method for adjusting screen magnification on electronic devices by displaying a DPI setting screen, calculating screen magnification using changed DPI and predetermined DIP, and changing the size of objects accordingly, allowing for simple manipulation and application across most existing applications without modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the screen size is increased to improve text visibility, then readability is improved, but device portability and compactness deteriorate
Solution Approach 1:
The patent introduces a virtual magnification dimension through software processing. Instead of physically enlarging the screen, it creates a magnified view layer that overlays or replaces the normal display, allowing users to view enlarged content on the same physical screen real estate.
Solution Approach 2:
The system changes the display parameter by applying a magnification factor to specific regions or elements on the screen. This virtual magnification adjusts the effective size of text and UI elements without altering the physical screen dimensions, thereby improving readability while maintaining device compactness.
2Illumination intensity
If the font size is increased to improve readability, then text visibility is improved, but layout consistency and application compatibility deteriorate
Solution Approach 1:
The patent applies magnification locally to specific regions, text elements, or UI components rather than uniformly scaling the entire display. This selective magnification allows text and important elements to be enlarged for better readability while keeping other interface elements at their original sizes to maintain layout consistency.
Solution Approach 2:
The magnification system is designed as a universal layer that works across different applications and content types. By implementing magnification at the system level rather than within individual applications, it ensures consistent functionality and compatibility across the entire device ecosystem.
3Illumination intensity
If a magnification tool is added to improve text visibility, then readability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a virtual magnification layer as an intermediary between the display hardware and the user's eyes. This software-based intermediary processes the display output and presents a magnified version without requiring additional physical components, thereby avoiding increases in device complexity.
Solution Approach 2:
The patent replaces potential mechanical or hardware-based magnification solutions (such as physical lenses or larger displays) with a software-based virtual magnification system. This substitution eliminates the need for additional mechanical components while achieving the same functional goal of improved text visibility.

AI summary
A method of adjusting a screen magnification of an electronic device is provided. The method includes displaying a Dots Per Inch (DPI) setting screen in order to adjust a screen magnification of an object that is to be displayed on a display unit of the electronic device, receiving information about changed DPI through the DPI setting screen, calculating a screen magnification using the changed DPI and a preset Device-Independent Pixel (DIP), changing a size of the object to correspond to the calculated screen magnification, and displaying the object according to the changed size.
