Solution Overview

Problem

Existing display devices do not consider power consumption during standby modes, leading to increased energy usage and heat generation, which is not addressed in prior art like JP-A-2016-161916.

Innovation Solution

A display device that includes an explanation screen displaying power consumption differences between two modes (coupling detection and signal detection) and allows users to select a mode based on their environment, reducing standby power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the display device continuously monitors video signal input to determine startup timing, then the startup responsiveness is improved, but the standby power consumption increases

Engineering Contradiction:
Improvestartup responsivenessVSAvoidstandby power consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic startup mode selection where the system can switch between two operational modes: a first mode with higher power consumption that provides faster startup response, and a second mode with lower power consumption that reduces standby energy usage. The user can select the appropriate mode based on their specific needs, making the system adaptable rather than static.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of the display device by introducing selectable startup modes with different power consumption characteristics. The control unit adjusts system behavior based on the selected mode, altering detection frequency and power usage parameters to balance between startup speed and energy consumption.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If the display device uses a more sensitive detection method for video signal input, then the detection precision is improved, but the power consumption during standby increases

Engineering Contradiction:
Improvevideo signal detection precisionVSAvoidstandby power consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts detection precision based on the selected startup mode. In the first mode, the system employs more sensitive and continuous detection methods for video signal input, ensuring high precision startup response. In the second mode, detection is reduced to basic coupling detection with lower power consumption, allowing users to balance precision against energy usage.

Inventive Principle:
Principle #15Dynamics

3Speed

If the display device maintains higher power during standby to enable faster startup, then the startup speed is improved, but the heat generation increases

Engineering Contradiction:
Improvestartup speedVSAvoidheat generation
Core Design Contradiction:
SpeedVSTemperature

Solution Approach 1:

The patent introduces a selectable parameter for startup mode that directly affects power consumption and heat generation during standby. The first mode maintains higher power levels enabling faster startup but generates more heat, while the second mode reduces power and heat generation at the cost of slower startup. This parameter change allows users to optimize for their specific environmental conditions and requirements.

Inventive Principle:
Principle #35Parameter changes
