Solution Overview

Problem

Existing display systems struggle to efficiently manage and transmit display region information when multiple display devices are used, particularly when a repeater is involved, as they do not effectively handle communication standards and display region resolutions.

Innovation Solution

A display system comprising multiple display devices, a computer, and a communication device that transmits output image information indicating the display region resolution to a video supply device, receives a video signal conforming to a different communication standard, converts it, and supplies the converted signal to the computer for displaying the image across the display devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a repeater is used to connect a host PC to multiple display devices, then the system can support multiple displays, but the transmission of display region information becomes problematic

Engineering Contradiction:
ImproveAbility to connect multiple display devicesVSAvoidDisplay region information transmission
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent introduces an EDID emulator as an intermediary component within the repeater that generates and transmits display region information to the host PC. This mediator bridges the information gap created by the repeater, allowing the host to receive accurate display region data from multiple displays through the repeater connection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If traditional display connection methods are used with a repeater, then multiple displays can be connected, but additional hardware such as an EDID emulator is required

Engineering Contradiction:
ImproveMulti-display supportVSAvoidSystem hardware configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the EDID emulator functionality directly into the repeater device, combining two previously separate components (repeater and EDID emulator) into a single integrated unit. This reduces system complexity by eliminating the need for separate hardware while maintaining multi-display support capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The repeater is designed to perform multiple functions: signal repetition for multiple display connections and EDID emulator functionality for display region information transmission. This multi-functional design eliminates the need for dedicated separate hardware components.

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

3Loss of information

If display region information is not transmitted through the repeater, then the system configuration is simpler, but the host PC cannot obtain resolution information from multiple displays

Engineering Contradiction:
ImproveResolution information acquisitionVSAvoidInformation transmission mechanism
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The EDID emulator acts as an intermediary that generates display region information based on the connected display devices and transmits this information to the host PC through the repeater connection, enabling the host to obtain resolution information without requiring direct connections to each display.

Inventive Principle:
Principle #24Intermediary (Mediator)
