Solution Overview

Problem

Existing display devices struggle to accurately and efficiently identify the target of control commands from input devices when multiple sources are connected, often requiring user intervention or separate control mechanisms like KVM switches.

Innovation Solution

The display device employs a processor to determine control command targets based on the position of indicators on the display, considering both the position and state information of the display device and source device, allowing dynamic priority adjustments to identify and process commands accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the display device uses a fixed priority method to process control commands, then the control logic is simple, but it cannot adapt to changing display states and content types

Engineering Contradiction:

Improveadaptability to display stateVSAvoidcontrol logic complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic priority determination by continuously monitoring display state information (such as whether the display device or source device is currently displayed) and control command type information, and adjusting the priority of control commands based on these changing conditions. This allows the system to adapt to different display scenarios without requiring a complete redesign of the control architecture.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs feedback mechanisms by acquiring display state information from the display device and source device, comparing it with current control commands, and using this feedback to dynamically adjust processing priorities. This closed-loop approach ensures the control system responds appropriately to changing conditions while maintaining manageable complexity through structured decision-making.

Inventive Principle:

Principle #23Feedback

2Ease of operation

If the display device requires user intervention to identify control targets, then control accuracy is high, but user experience is degraded due to additional操作步骤

Engineering Contradiction:

Improveease of controlVSAvoidtime for target identification

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The display device automatically identifies the target of control commands by analyzing the position of indicators on the display and the current display state, without requiring user intervention. The system serves itself by autonomously determining whether the control command is intended for the display device or the source device, thereby eliminating additional operational steps and reducing time loss.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual user intervention (mechanical interaction) with automated electronic detection and analysis. The system uses processor-based analysis of indicator positions and display states to substitute for the mechanical action of user selection, achieving both ease of operation and time efficiency.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If the display device uses separate control mechanisms like KVM switches, then control target identification is accurate, but device complexity increases

Engineering Contradiction:

Improvecontrol target identification accuracyVSAvoidcontrol mechanism complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges the control target identification function into the display device itself, combining the indicator position detection, display state monitoring, and control command routing capabilities into a single integrated system. This eliminates the need for separate external control mechanisms like KVM switches while maintaining accurate control target identification through the unified architecture.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The display device is designed with multi-functionality, serving both as the display output device and as the control command processing unit. By making the display device universal in its capabilities, the system eliminates the need for dedicated control mechanisms, reducing overall system complexity while preserving accurate control target identification through its indicator-based detection system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A display device includes a first interface connected to an input device; a second interface connected to a source device; a display; at least one processor; and memory storing instructions, that, when executed by the at least one processor, cause the display device to control the display to display a first image in a first region of the display, and display a second image in a second region of the display, wherein the second image is received from the source device via the second interface; determine a priority for processing a control command associated with an indicator corresponding to the input device based on a position of the indicator on the display, and identify a device, from among the display device and the source device, to process the control command based on the priority.
