Dual Processor Display Control for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in efficiently managing display areas and reducing power consumption while maintaining display quality, particularly due to the need for smaller bezels and longer battery life in portable devices.
Innovation Solution
An electronic device with a first processor and a second processor, where the first processor detects operations and determines the range of display control authority to be provided to the second processor, allowing the second processor to generate and display a screen independently in specific areas, optimizing display management and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a single processor controls the entire display, then display control is centralized and simple, but power consumption increases and interface flexibility is limited
Solution Approach 1:
The display control function is segmented into multiple independent processors: a first processor that detects operations and determines display control authority ranges, and a second processor that generates and displays screens within assigned ranges. This segmentation allows power consumption to be reduced by distributing processing loads across multiple lower-power units rather than relying on a single high-power processor.
2Adaptability or versatility
If display control authority is distributed to multiple processors, then power consumption is reduced and interface flexibility is enhanced, but system complexity and coordination overhead increase
Solution Approach 1:
The system implements dynamic display control authority allocation where the first processor detects operations and dynamically determines which ranges of the display interface should be controlled by the second processor. This dynamic allocation enhances interface flexibility by adapting control distribution to current operational needs while managing system complexity through conditional rather than static assignments.
3Area of stationary object
If the bezel size is reduced for spatial efficiency, then display area is maximized, but the challenge of managing multiple display areas with limited space increases
Solution Approach 1:
The display interface is divided into multiple areas with different local qualities and control characteristics. The first processor determines specific ranges of the display interface that should be controlled by the second processor based on detected operations. This allows different portions of the display to have optimized control mechanisms tailored to their specific functions, maximizing the utility of the limited display area while managing complexity through localized control strategies.

AI summary
An electronic device and a method performed in the electronic device are provided. The electronic device includes a display module, and a first processor and a second processor that are electrically connected with the display module. The first processor is configured to detect an operation performed in the electronic device, determine a range of display control authority to be provided to the second processor according to the operation, and provide the range of the display control authority to the second processor. The second processor is configured to generate a display screen corresponding to the range of the display control authority and provide the display screen through the display module.
