Multi-Device Touchscreen Content Synchronization via Group Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with touchscreen panels face limitations in extending display size due to fixed bezel areas, restricting the ability to view content on large screens, and require a method to conveniently control multiple devices to output the same content and events across multiple displays.
Innovation Solution
A system and method that allows electronic devices to be paired for simultaneous content output, using touch inputs to control display direction, segment content, and manage notification bars across devices, enabling seamless sharing and control of content and events through short-range wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If touchscreen panel wiring structure is modified to minimize bezel areas, then display area is extended, but control complexity of multiple devices increases
Solution Approach 1:
The patent merges multiple electronic devices into a single group that functions as one unified display system. The controller integrates control of multiple touchscreens, allowing them to display content simultaneously or in sequence, effectively combining their display areas while managing control through a centralized interface that reduces operational complexity.
Solution Approach 2:
The controller is designed with multi-functionality to handle various operations across multiple devices including content transmission, synchronization, touch input reception, and display management. This universal control mechanism simplifies the user interface while managing the complexity of coordinating multiple devices with different display areas.
2Adaptability or versatility
If multiple electronic devices are paired to form one group for simultaneous content display, then viewing experience is enhanced, but device pairing and control complexity increases
Solution Approach 1:
The pairing mechanism operates autonomously where the controller automatically manages device discovery, pairing, and group formation. Once devices are paired, they self-organize into a coordinated display system where content is automatically transmitted and synchronized across all devices, reducing the need for manual configuration and control.
Solution Approach 2:
The controller acts as an intermediary that manages communication and coordination between multiple electronic devices. It handles content distribution, synchronization timing, and touch input routing, simplifying the interaction model while enabling complex multi-device functionality for enhanced viewing experiences.
3Ease of operation
If touch inputs are applied throughout touchscreens including bezel areas, then user interface flexibility is improved, but input processing complexity increases
Solution Approach 1:
The touchscreen input area is segmented into functional zones including active display areas and bezel areas. The controller processes touch inputs by identifying their location and type, routing them to appropriate applications or functions. This segmentation allows flexible interface design where bezel areas can be used for additional controls while maintaining organized input processing.

AI summary
Disclosed herein are an electronic device and a method of controlling the same. The electronic device may include a controller configured to generate a group of a plurality of electronic devices by paring the electronic device with at least one electronic device through the communication unit and to control the plurality of electronic devices included in the group to share at least part of content and to simultaneously display the content on touchscreens of the plurality of electronic devices. Upon sequential reception of touch inputs applied to the touchscreens of the electronic devices included in the group, the controller can display at least part of the content on the touchscreen of each electronic device included in the group on the basis of the number of touch inputs and touch input reception time.
