Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual display information handling systems face challenges in managing power efficiently due to the substantial energy requirements of display screens, which can heavily tax system performance and battery life, especially in mobile devices, where traditional input devices are being replaced by touchscreens and motion sensing technologies, necessitating innovative power management strategies.
Innovation Solution
A dual display information handling system that incorporates a sensor module and power management application to determine power savings based on the orientation of the displays and the context of software applications running, using sensors such as motion, image, and sound sensors to adjust power allocation and reduce energy consumption by dimming or powering down non-active screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual display screens are used to enhance functionality and user experience, then adaptability and versatility are improved, but energy consumption increases substantially
Solution Approach 1:
The system dynamically adjusts display power management based on real-time orientation detection and application context. The display mode selector continuously monitors sensor data and software context to adaptively switch between different power management modes, optimizing the balance between display functionality and energy consumption.
Solution Approach 2:
The system changes operational parameters by adjusting brightness levels, refresh rates, and power allocation to each display based on detected orientation and application type. This allows the dual display system to maintain versatility while consuming less energy by adapting parameters to actual usage scenarios.
2Illumination intensity
If display brightness is increased to improve visibility and user experience, then illumination intensity is improved, but energy consumption increases
Solution Approach 1:
The system applies different brightness levels to different displays based on their orientation and usage context. Instead of uniformly adjusting brightness across both displays, the system selectively optimizes illumination for each screen according to its specific role and viewing conditions, reducing overall energy consumption while maintaining necessary visibility.
3Loss of energy
If sensors and power management software are added to enable dynamic power adjustment, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The sensor module serves multiple functions: detecting device orientation, determining display positioning, and triggering appropriate power management modes. The power management application also performs multiple roles including monitoring energy consumption, selecting display modes, and coordinating with the display driver. This multi-functionality reduces the need for separate dedicated components for each function.

AI summary
An information handling system may have two display screens including a first integrated display device and a second integrated display device attached via a hinge. A processor determines a first relative orientation of the first integrated display device to the second integrated display device from a plurality of orientation sensors and further determines working software application context by detecting at least one software application running on the information handling system. The system further includes a controller module deploys a power savings strategy. For example, the controller may restrict power usage to the first or second integrated display device based on the first relative orientation and the working software application context.
