Brightness Controller for Multi-Display Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies for reducing power consumption in computers with multiple displays do not account for software-specific brightness control, leading to inefficient power management.
Innovation Solution
A brightness controller system comprising display modules, a specifying module, and a controller that adjusts the brightness of each display based on the features of the applications running on them, using a setting file to determine optimal brightness levels for different software applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional brightness control is applied to multiple displays, then power consumption is reduced through uniform brightness adjustment, but software-specific display requirements are not met
Solution Approach 1:
The patent segments the brightness control function by creating separate control mechanisms for each display module. The specifying module identifies which display module should display which application, and the controller adjusts brightness independently for each display based on its specific software requirements, rather than applying uniform brightness control across all displays.
Solution Approach 2:
The patent implements local quality by allowing different brightness levels for different display modules based on their specific software requirements. Each display module receives customized brightness control tailored to the application it displays, such as higher brightness for video playback and lower brightness for text editing, optimizing both power consumption and display quality for each specific use case.
2Use of energy by moving object
If individualized brightness control is implemented for each display based on software features, then power consumption is optimized, but system complexity increases
Solution Approach 1:
The patent achieves universality by designing a multi-functional brightness control system that can handle multiple applications and display scenarios through a single integrated controller. The controller reads application information, determines brightness requirements, and applies appropriate brightness levels across different display modules, making the system adaptable to various software types without requiring separate control mechanisms for each application.
Solution Approach 2:
The system implements self-service by automatically detecting the running application and adjusting display brightness accordingly without user intervention. The specifying module and controller work autonomously to monitor application states and modify brightness settings based on software features, reducing the need for manual configuration while optimizing power consumption.

AI summary
According to one embodiment, a brightness controller includes a plurality of display modules, a specifying module, and a controller. The display modules each include a display screen the brightness of which is adjustable. The specifying module specifies at least one of the display modules to display an application. The controller individually controls the brightness of the display screen of the display module specified by the specifying module based on features of the application displayed on the display module.
