OPS Interface Power Conversion for Lower Display Component Count

Solution Overview

Problem

Existing open pluggable specification (OPS) interface standards require display devices to include large or separate power supply parts to power connected electronic devices, leading to increased component count and manufacturing costs due to unnecessary power supply components.

Innovation Solution

An interface apparatus with a substrate that includes connectors for signal interfacing between electronic and display devices, featuring a power supply part with AC/DC and DC/DC converters to receive and convert power from an external or display device's power supply, reducing the need for internal power supply components in the display device.

VSEngineering Contradiction Analysis

1Power

If display devices include large or separate power supply parts to power connected electronic devices, then power delivery capability is improved, but device complexity and manufacturing costs increase

Engineering Contradiction:

Improvepower delivery capabilityVSAvoiddevice complexity

Core Design Contradiction:

PowerVSDevice complexity

Solution Approach 1:

The power supply part is extracted from the display device and integrated into the interface apparatus. The interface apparatus includes a power connector that receives power from the display device's power supply part and a power supply circuit that converts and outputs power to the electronic device, thereby removing the need for separate power supply components in the display device.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The interface apparatus acts as an intermediary between the display device and the electronic device. It receives power from the display device through a power connector, converts the power through its own power supply circuit, and delivers it to the electronic device, thus enabling power delivery without requiring the display device to have built-in power supply components for this purpose.
