Rear Display UI Mirroring for Touch Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electronic devices with rear displays need to flip the device to access content on the rear display, and existing methods for controlling these devices are not efficient for user interaction.
Innovation Solution
A user terminal apparatus with a main display on the front and a sub display on the rear, where the processor controls the display to show UI elements from the rear display on the front display in response to touch inputs, allowing overlay, transparency, and gesture recognition.

Engineering Contradiction Analysis
1Area of stationary object
If a display is extended to the back of the electronic apparatus, then the display area is increased, but the user needs to flip the apparatus to see the contents
Solution Approach 1:
The patent copies the rear display content to the front display, allowing users to view and interact with rear display content without flipping the device. The processor detects touch inputs on the rear display and reproduces the corresponding UI on the front display, creating a virtual copy of the rear interaction interface.
Solution Approach 2:
The front display acts as an intermediary between the user and the rear display content. Instead of requiring direct viewing of the rear display, the front display mediates by showing copied content and transmitting touch inputs from the front to the rear display, enabling indirect interaction.
2Adaptability or versatility
If the display is extended to the back side, then various applications are enabled, but the control method becomes complex
Solution Approach 1:
The front display serves multiple functions: it displays normal front-side content, copies rear display content for viewing, and acts as a touch input interface for controlling the rear display. This multi-functionality reduces the need for separate control mechanisms and simplifies the overall system.
Solution Approach 2:
The patent merges the front display and rear display into a unified interaction system. Touch inputs detected on the front display are transmitted to control the rear display, combining both displays' functionalities into a single integrated control interface that reduces operational complexity.

AI summary
A user terminal apparatus is provided. The user terminal device includes a display having 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, in response to a predetermined touch input being input on the sub display area, control the display to display a UI displayed on the sub display area on the main display area.
