Solution Overview

Problem

Existing display technologies fail to seamlessly integrate multiple screens into a single, unified display experience, limiting user interaction and content alignment across connected devices.

Innovation Solution

A method and system for operating multiple display devices in a 'twin mode' where screens are merged, allowing a single pointer input to control operations across devices, enabling synchronized content display and user-friendly manipulation of linked screens.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple display devices are connected to form a merged screen, then the display area is increased, but the operation complexity increases

Engineering Contradiction:
Improvedisplay areaVSAvoidoperation complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent merges multiple display devices into a unified twin mode interface where two separate screens function as a single display area. The controller integrates the display regions of both devices, allowing content to span across them seamlessly, thus increasing the effective display area while maintaining unified control

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The controller is designed to handle multiple input methods (remote control, touch screen, key input) and route them appropriately to either display device. This multi-functional capability allows a single control interface to manage the entire merged screen system, reducing operational complexity despite the increased display area

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple display devices operate independently, then each device can be controlled separately, but user interaction across devices becomes difficult

Engineering Contradiction:
Improvedevice independenceVSAvoiduser interaction
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The controller acts as an intermediary between the user and the two display devices. It receives control signals from various input sources and determines which display device should respond, enabling seamless cross-device interaction without requiring users to understand the underlying device architecture

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent introduces a new operational dimension by implementing a twin mode that transcends the traditional single-device control model. This mode allows content and control to flow freely between devices, creating a unified interaction space that combines device independence with ease of operation

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If a single image is displayed on multiple devices, then the display flexibility is increased, but the content alignment precision decreases

Engineering Contradiction:
Improvedisplay flexibilityVSAvoidcontent alignment precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The controller applies different processing to different regions of the merged screen. It determines which display device should show which portion of the content based on the current mode (split screen, extended screen, or duplicated content), allowing precise alignment control for each local region while maintaining overall display flexibility

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts display parameters such as screen resolution, refresh rate, and content distribution between the two devices. By changing these parameters based on the selected twin mode, the system achieves both display flexibility and content alignment precision across different operating scenarios

Inventive Principle:
Principle #35Parameter changes

4Measurement precision

If separate control interfaces are used for each display device, then the control specificity is improved, but the input management complexity increases

Engineering Contradiction:
Improvecontrol specificityVSAvoidinput management complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The controller is designed with multi-functional capabilities to handle various input methods (remote control, touch screen, key input) and route them to the appropriate display device. This universal control interface maintains control specificity while reducing input management complexity through centralized intelligence

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A display device operation method according to an embodiment of the present invention comprises the steps of: operating in a twin mode in which a merge screen obtained by merging a first screen of the display device and a second screen of another display device connected to the display device can be used by linking a plurality of display devices including the display device; displaying a pointer on the first screen; acquiring a user input for the displayed pointer; and performing an operation corresponding to the acquired user input through one or more of the plurality of display devices.
