Switch Assembly for Display Signal Routing in Electronic Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tablet computers with combined monitor and computer functions face high power consumption when in display mode due to the continuous operation of the main control chip, which is difficult to meet low power consumption requirements.
Innovation Solution
Incorporating a switch assembly to selectively route display signals from either the processor or an external controller, allowing the processor to enter a low power state when in host mode and the controller to handle display signals in display mode, thereby reducing overall power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the main control chip continues to operate in display mode, then the display function is maintained, but the power consumption increases significantly
Solution Approach 1:
The patent divides the display control function into two independent parts: a processor for host mode operations and a controller for display mode operations. The switch assembly separates the signal paths, allowing each component to operate independently in its designated mode, thereby reducing overall power consumption when in display mode.
Solution Approach 2:
The patent implements dynamic mode switching between host mode and display mode using a switch assembly. The system can dynamically transition between different operational states, activating only the necessary components for the current mode, which optimizes power consumption based on actual usage requirements.
2Adaptability or versatility
If the tablet computer supports display mode, then the functionality is enhanced, but the power consumption in host mode increases
Solution Approach 1:
The patent segments the control architecture by introducing a dedicated controller that handles display mode functions separately from the main processor. This segmentation allows the processor to enter low-power states during display mode without compromising the display functionality, thus maintaining versatility while reducing power consumption in host mode.
Solution Approach 2:
The switch assembly acts as an intermediary component that manages signal routing between the processor, controller, and display device. It mediates between different operational modes, ensuring that the correct signal source is connected to the display device based on the current mode, thereby enabling mode switching without power consumption penalties.
3Use of energy by moving object
If a switch assembly is introduced to route signals, then the power consumption is reduced, but the device complexity increases
Solution Approach 1:
The switch assembly is designed as a multi-functional component that handles signal routing for both host mode and display mode operations. By making this single component responsible for multiple switching functions, the patent reduces the need for separate dedicated circuits for each mode, thereby limiting the increase in device complexity while achieving significant power savings.

AI summary
An apparatus includes a display device, a switch assembly configured to switch a signal source of a display signal for the display device, a processor connected to the switch assembly and configured to provide signal to the display device through the switch assembly in a first mode, and a controller connected to the switch assembly and configured to provide the display signal to the display device through the switch assembly in a second mode.
