Screen Color Gamut Control for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face high power consumption and resource wastage when consistently displaying images in a single color gamut space, leading to excessive power usage and reduced user experience, especially during tasks that do not require enhanced color display.
Innovation Solution
A method and apparatus for controlling screen color gamut by displaying a control member to switch between multiple color gamut spaces, acquiring its state, and adjusting the screen's color gamut space accordingly, allowing users to select the most suitable color gamut for their visual needs, thereby optimizing power usage and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the screen consistently displays images in a single color gamut space to ensure color accuracy, then color display quality is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic color gamut switching that adapts the screen's color gamut space based on real-time detection of displayed content characteristics and user preferences. The system transitions between different color gamut modes (e.g., wide color gamut for photos, standard color gamut for videos) to optimize both display quality and power consumption, making the color gamut parameter variable rather than fixed.
Solution Approach 2:
The system changes the color gamut parameter of the screen based on detected content types and user settings. By adjusting the color gamut parameter dynamically - expanding it when high color fidelity is needed and reducing it when standard coloring suffices - the system achieves energy efficiency while maintaining appropriate display quality for different scenarios.
2Illumination intensity
If the screen uses a larger color gamut to display more vibrant colors, then display effect is improved, but power consumption increases
Solution Approach 1:
The patent applies different color gamut characteristics to different display scenarios based on content requirements. Instead of uniformly applying wide color gamut to all content, the system selectively enhances color saturation and gamut only when the displayed content (such as photos) benefits from it, while using standard gamut for content that doesn't require enhanced colors, thereby reducing overall energy consumption.
Solution Approach 2:
The system applies enhanced color gamut only partially - specifically when and where it adds value to the viewing experience. By detecting content types and applying wide color gamut only to appropriate content (like photos) rather than all content, the system achieves improved display effect where needed while avoiding unnecessary energy consumption during standard content playback.
3Device complexity
If the screen maintains a fixed color gamut space to simplify system operation, then system complexity is reduced, but adaptability to different display needs decreases
Solution Approach 1:
The system automatically detects the type of content being displayed and autonomously selects the appropriate color gamut mode without requiring manual user intervention. The detection module identifies content characteristics (photos, videos, general content) and the system self-adjusts the color gamut parameters accordingly, providing adaptability while keeping the user interface simple.
Solution Approach 2:
The system incorporates a unified color gamut management mechanism that handles multiple content types and user preferences through a single adaptive framework. This multi-functional approach allows the same system to serve diverse display needs - from photo viewing to video playback - by dynamically adjusting color gamut parameters, thereby achieving versatility without proportionally increasing operational complexity.

AI summary
Disclosed in embodiments of the present application are a screen color gamut control method and apparatus, an electronic device, and a storage medium. The method comprises: displaying a control, the control being configured to control the screen to switch between different color gamut spaces; acquiring the state of the control, the state being used for representing the color gamut space to which the screen is controlled to switch; and adjusting the color gamut space of the screen to make same be switched to the color gamut space corresponding to the state of the control. By means of the present method, when the control is displayed, the color gamut space of the screen is adjusted by the control to switch the color gamut space to that corresponding to the state of the control, so that users can enjoy different color experiences, thereby improving user experience.
