Selective Pixel Intensity Reduction for Display Power Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The excessive energy consumption of modern high-definition and ultra-HD display screens, particularly in devices like computer monitors, televisions, and mobile communication devices, due to the need for high pixel density, which is not always necessary for all content types, leading to a desire for reducing power usage in appropriate use cases.
Innovation Solution
Implementing systems and methods that selectively reduce pixel intensity through automated processes, using software code executed by hardware processors to generate lower resolution images with reduced power consumption, while allowing optional human review, and applying masks to reduce pixel intensity in specific regions of images, such as the image border, to lower overall display power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high pixel density is used to display high-definition and ultra-HD images, then image quality is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by selectively reducing pixel intensity in specific regions (such as borders or less important areas) while maintaining full intensity in other regions. This allows the display to use lower power consumption modes in certain areas while preserving high image quality in critical areas, thus resolving the contradiction between overall image quality and power consumption.
Solution Approach 2:
The patent implements partial action by applying intensity reduction only to a subset of pixels rather than the entire display. This partial reduction achieves power savings while maintaining sufficient image quality in the unaffected regions, balancing the trade-off between power consumption and image quality.
2Use of energy by moving object
If selective pixel intensity reduction is applied to reduce power consumption, then power consumption is lowered, but image quality deteriorates
Solution Approach 1:
The patent maintains high image quality in specific local regions while applying intensity reduction in other regions. This localized approach ensures that critical areas of the image retain full quality, minimizing the perceived deterioration while achieving overall power savings.
Solution Approach 2:
The patent employs feedback mechanisms to monitor and adjust pixel intensity reduction based on image content analysis. By feedback-based adjustment, the system optimizes the balance between power consumption and image quality, ensuring that quality deterioration remains acceptable while maximizing power savings.

AI summary
According to one implementation, a system for enhancing energy efficiency during display of an image through selective reduction of pixel intensity includes a computing platform having a hardware processor and a memory storing a software code. The hardware processor is configured to execute the software code to receive a first image including multiple pixels and having a first display power consumption when displayed on a display, and to change the intensity of each of a predetermined subset of the pixels of the first image into a predetermined intensity to generate a second image. The second image has a second display power consumption when displayed on the display, the predetermined intensity being such that the second display power consumption is lower than the first display power consumption.
