Always-On Display Mirroring Control Without Screen Wake-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen-casting technologies require users to manually wake up the terminal device to control the screen-casting status when in an always on display or black screen state, leading to high operation complexity and increased power consumption.
Innovation Solution
A method that allows users to control the screen-casting status through operations on an always on display or black screen interface, enabling the terminal device to execute corresponding instructions without waking up the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually wake up the terminal device to control screen-casting status, then control functionality is available, but operation complexity increases and power consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring the always-on display interface with screen-casting control functionality before the device is fully activated. Control buttons and interfaces are prepared in advance on the low-power display, allowing users to immediately control screen-casting operations without needing to wake the device from sleep mode. This resolves the contradiction by enabling control operations while the device remains in a low-power state.
Solution Approach 2:
The always-on display interface is designed to serve multiple functions simultaneously: it displays basic information (time, notifications) while also providing full screen-casting control capabilities. This multi-functionality allows the same interface to reduce operation complexity for screen-casting control without requiring additional power-consuming modes, as the display is already active for other purposes.
2Ease of operation
If the terminal device wakes up to execute control instructions, then control functionality is available, but power consumption increases
Solution Approach 1:
The control interface and processing capabilities are preliminarily prepared and maintained in a ready state on the always-on display. When control instructions are received, the device can execute them directly without transitioning from a low-power state, as the necessary software and interface elements are already loaded and active on the always-on display system.
Solution Approach 2:
The always-on display acts as an intermediary layer between the user and the main device system. It receives and processes control instructions for screen-casting operations independently, serving as a mediator that handles control tasks without requiring the main device to wake up from sleep mode, thus reducing overall power consumption while maintaining control accessibility.
3Ease of operation
If screen-casting control is available on always on display interface, then operation complexity reduces, but interface complexity increases
Solution Approach 1:
The patent extracts screen-casting control functionality from the main device interface and places it specifically on the always-on display interface. By separating this control function into a dedicated location on the always-on display, the main device interface remains simple while the always-on display develops specialized control elements. This extraction reduces overall operational complexity while managing interface complexity through functional separation.
Solution Approach 2:
Different parts of the display system are assigned different functions with appropriate complexity levels. The always-on display interface is locally optimized with screen-casting control elements where they are most needed, while the main device interface maintains its original simplicity. This local quality approach allows control functionality to be enhanced in specific areas without increasing complexity across the entire device interface system.
