Multifunction Display Port Bypassing Processor for External Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices cannot operate as peripheral or external displays while in a power off state, as they require internal power to function and lack the capability to receive and display data without processor intervention.
Innovation Solution
The development of apparatuses with a multifunction display port that can receive electrical energy and display data from a host device even when in a power off state, bypassing the processor, and include a display system multiplexer to direct data and energy based on the device's power state, allowing operation as a peripheral or external display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device operates as a peripheral display while in power off state, then additional functionality is enabled, but the device requires receiving electrical energy from host device through the display port
Solution Approach 1:
The display port is designed to serve multiple functions: it acts as both a data display interface and a power reception interface. The same physical port and connector structure can receive both display data signals and electrical energy from the host device, eliminating the need for separate power input hardware and enabling the device to function as a peripheral display without requiring its own internal power source.
2Use of energy by moving object
If the device bypasses the processor to display data directly, then power consumption is reduced, but the device loses normal computing device operation capability
Solution Approach 1:
The device dynamically switches between two operational modes based on power availability: when powered off or with limited power, it operates in a simplified mode that bypasses the processor and displays data directly through the display port; when powered on with sufficient power, it transitions to full computing device operation with complete processor functionality. This dynamic mode switching allows the device to adapt its operational capability to match available power resources.
3Adaptability or versatility
If the device includes a display system multiplexer to direct data and energy, then data routing flexibility is improved, but device complexity increases
Solution Approach 1:
A display system multiplexer is introduced as an intermediary component that sits between the display port and the display system. This multiplexer intelligently routes incoming signals and power based on the device's operational state: it can direct display data to the display panel when in peripheral display mode, or route power to appropriate system components when in full operation mode. By centralizing the routing logic in this single intermediary component, the patent achieves flexible data and power distribution without proportionally increasing overall system complexity.

AI summary
According to examples, an apparatus may include a processor, a display system and a multifunction display port. The multifunction display port may include a display port connector and an input power connector. In addition, based on the apparatus being in a power off state and being connected to a host device, the display system may receive input electrical energy through the input power connector from a host device, receive display data through the display port connector from the host device, and display the display data received from the host device while bypassing the processor.
