Dual-Side Display Lock Screen Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user terminal devices with extended displays face challenges in managing information across multiple display areas, such as deciding which information to provide on each area and implementing effective manipulation methods between them, due to the limitations of divided display surfaces.
Innovation Solution
A user terminal apparatus with a main display area on the front side and a sub-display area extended from the main display area to the rear side, controlled by a processor that provides lock screens and home screens based on user input, allowing different lock screens and home screens to be displayed on each area, enhancing usability and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a display is extended to the back side of the electronic apparatus creating multiple display areas, then the total display area is increased, but it becomes difficult to decide which information should be provided on which display area and requires complex manipulation methods
Solution Approach 1:
The display is segmented into multiple independent display areas (front display area and back display area) that can be independently controlled. Each display area can show different lock screens and home screens, allowing information to be divided and presented across separate surfaces rather than competing for the same space.
Solution Approach 2:
The display extends from the front surface to the back surface of the electronic apparatus, utilizing the third dimension (depth) to create additional display areas. This dimensional transition allows users to access different information sets by physically rotating or flipping the device, simplifying the manipulation model compared to managing multiple displays on a single plane.
2Loss of information
If multiple display areas are created on different surfaces, then more information can be displayed simultaneously, but the complexity of managing information across display areas increases
Solution Approach 1:
Information management is segmented by display area, with each surface (front and back) having its own dedicated lock screen and home screen. This segmentation eliminates the complexity of managing a single unified information space across multiple surfaces, as each surface operates independently with its own set of information.
Solution Approach 2:
Instead of consolidating all information management functions into a single complex system, the patent inverts the approach by providing separate, simplified information management for each display surface. Each surface has its own lock screen and home screen that can be independently configured and managed, reducing overall system complexity.
3Adaptability or versatility
If different lock screens and home screens are provided for each display area, then user interaction is enhanced, but the system complexity increases
Solution Approach 1:
The user interaction system is segmented into independent modules for each display area, with separate lock screens and home screens that can be independently configured. This modular approach enhances adaptability by allowing different interaction patterns on different surfaces while keeping system complexity manageable through clear separation of functions.
Solution Approach 2:
The patent implements a universal framework where the same basic lock screen and home screen functionality is replicated across multiple display areas. This multi-functionality approach allows the system to handle different display surfaces with a standardized set of functions, enhancing versatility without proportionally increasing complexity.

AI summary
A user terminal apparatus is provided. The user terminal apparatus includes a display consisting of a main display area disposed on a front side of the user terminal apparatus and a sub display area extended from one side of the main display area to be disposed on at least one area of a rear side of the user terminal apparatus, and a processor configured to provide a lock screen to a display area of at least one of the main display area and the sub display area and, in response to a user input of releasing the lock screen being sensed, control the display to provide a different home screen based on a display area where the user input is sensed.
