Dynamic Pixel Density Adjustment for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High pixel density in display screens leads to increased power consumption, which is not necessary in all scenarios, as user demands vary based on the type of content being displayed.
Innovation Solution
A method and device that automatically set the pixel density of a display screen based on the file attribute of the content to be displayed, using a pre-stored pixel density model, allowing for dynamic adjustment and optimization based on display history to reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If pixel density is increased to meet user demands, then display quality is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the pixel density adjustable rather than fixed. The system dynamically changes pixel density based on the type of content being displayed, switching between high pixel density for detailed content (images, videos) and low pixel density for text content, thereby optimizing the balance between display quality and power consumption.
Solution Approach 2:
The patent applies local quality by differentiating pixel density requirements for different types of content. Instead of using uniform high pixel density for all content, the system applies high pixel density only where necessary (for images and videos that benefit from it) and low pixel density for text content, optimizing energy efficiency while maintaining appropriate display quality for each content type.
2Illumination intensity
If pixel density is consistently high to ensure quality display, then display quality is maintained, but battery life is reduced
Solution Approach 1:
The system dynamically adjusts pixel density based on content type, switching between high and low settings rather than maintaining a consistently high setting. This dynamic adjustment extends battery life by using low pixel density for text content while preserving high pixel density for content that benefits from it, optimizing the duration of action.
Solution Approach 2:
The patent changes the pixel density parameter based on the type of content being displayed. By modifying this key parameter dynamically (high for images/videos, low for text), the system maintains appropriate display quality while significantly reducing power consumption and extending battery life.
3Use of energy by moving object
If automatic pixel density adjustment is implemented, then power consumption is reduced, but system complexity increases
Solution Approach 1:
The system performs preliminary classification of content type before displaying, using file attributes to determine whether the content is text, image, or video. This preliminary action enables automatic pixel density adjustment without requiring complex real-time analysis during display, reducing system complexity while achieving power consumption savings.
Solution Approach 2:
The system automatically determines the appropriate pixel density based on file attributes without requiring manual user intervention. The device serves itself by autonomously selecting high or low pixel density modes based on the content type, simplifying the user experience while reducing power consumption through intelligent automation.

AI summary
A display method, a display device, a terminal device, and a storage medium are provided. The display method includes: extracting a file attribute of a file to be displayed; automatically setting, according to the file attribute of the file to be displayed, a pixel density of a display screen for displaying the file by searching the pixel density corresponding to the file attribute of the file from a pre-stored pixel density model; and displaying the file according to the pixel density.
