Lock Screen Application Icon Segmentation for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content control apparatuses for mobile terminals are cumbersome for users as they limit functions, making it difficult to operate and access desired applications, especially when the touch screen is in a locked state.
Innovation Solution
A mobile terminal with a wireless communication unit, display unit, and controller that allows wireless communication and displays application program icons on the lock screen, enabling users to execute applications even when the touch screen is locked, by activating specific display regions and requesting passwords for unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the touch screen is locked to protect security, then security is improved, but user accessibility to applications deteriorates
Solution Approach 1:
The lock screen is segmented into multiple functional regions: a first display region for password input and a second display region for application icons. This segmentation allows the screen to simultaneously maintain security (through password protection in the first region) and provide application accessibility (through visible icons in the second region), resolving the contradiction between security and ease of operation.
2Reliability
If all functions are restricted on lock screen to maintain security, then security is improved, but device complexity increases due to multiple unlock operations required
Solution Approach 1:
The lock screen is designed with multi-functionality, serving both as a security barrier (password input region) and as an application launch interface (application icon region). This universal design allows users to access applications directly from the lock screen without requiring full unlocking, reducing operational complexity while maintaining security through the preserved password input capability.
3Ease of operation
If application icons are displayed on lock screen to improve accessibility, then ease of operation is improved, but energy consumption increases due to extended display time
Solution Approach 1:
The display applies local quality by showing application icons selectively in the second display region while maintaining the password input functionality in the first region. This localized approach allows the system to provide application accessibility without requiring the entire screen to remain fully active and editable, enabling the display to enter lower-power states more quickly while still providing useful functionality.

AI summary
A mobile terminal including a wireless communication unit configured to wirelessly communicate with at least one other terminal; a display unit including a touch screen; and a controller configured to enter the touch screen into a locked state, to display a lock screen and an application program icon for executing an application program on the lock screen when entering the locked state.
