Docking Display Hub Integrating MST Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional displays and docking stations occupy excessive space when used together, and the video distribution hub remains active even when not fully utilized, leading to unnecessary power consumption.
Innovation Solution
A docking display with a multi-stream transport (MST) port, MST controller, control circuit, display panel, and hub that efficiently manages multiple video streams, allowing the hub to enter sleep mode when not in use, thereby reducing power consumption and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a docking station is used to expand video interfaces for connecting multiple displays and devices, then the interface expansion capability is improved, but the space occupation increases because the display and docking station are two separate devices
Solution Approach 1:
The patent combines the display function and docking station function into a single integrated device. The display device includes a built-in hub that can distribute video signals to multiple displays, eliminating the need for a separate docking station and reducing space occupation while maintaining interface expansion capability
2Adaptability or versatility
If the hub is set on the video transmission path to enable video distribution, then the video distribution function is improved, but the power consumption increases because the hub cannot be turned off when connected to only one display
Solution Approach 1:
The hub's operational state is made dynamic rather than static. The hub can automatically adjust its工作状态 between active and sleep modes based on the number of connected displays. When only one display is connected, the hub enters sleep mode to reduce power consumption; when multiple displays are connected, it activates to provide video distribution
Solution Approach 2:
The system implements feedback control where the hub monitors the connection status of displays and adjusts its operational state accordingly. This feedback mechanism enables the hub to enter sleep mode when not fully utilized (single display connection) and activate when needed (multiple display connections), optimizing power consumption while maintaining video distribution functionality

AI summary
A docking display has a multi-stream transmission (MST) port, an MST controller, a display panel, a control circuit, a hub, a first video output port, and a second video output port. The MST port is used for inputting at least one video stream. The MST controller is used for processing the at least one video stream. The control circuit is used for outputting a first video stream of the at least one video stream to the display panel to drive the display panel to display images according to the first video stream. When the at least one video stream has a plurality of video streams, the hub outputs a second video stream of the video streams from a first output port of the hub to the first video output port, or from a second output port of the hub through the MST controller to the second video output port.
