Display Power Reduction via Dynamic Image Quality and User Rewards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack an efficient method to reduce power consumption while maintaining acceptable image quality, especially in environments where screen brightness needs to be adjusted to prevent glare.
Innovation Solution
An electronic device is designed with a display, memory storing image quality processing information for various power consumption reduction levels, and a processor that executes instructions to identify power consumption reduction amounts, calculate user rewards, and control the display to show reward information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the brightness of the display is reduced to prevent glare in dark environments, then the harmful effect of glare is reduced, but the visibility and viewing comfort deteriorate
Solution Approach 1:
The display brightness is dynamically adjusted based on real-time detection of ambient lighting conditions. The system transitions between different brightness levels (first brightness level in bright environments, second brightness level in dark environments) to adapt to changing environmental conditions, thereby preventing glare while maintaining visibility where needed
2Use of energy by moving object
If power consumption reduction mode is implemented by reducing display brightness, then power consumption is reduced, but image quality deteriorates
Solution Approach 1:
The system applies different image quality processing parameters to different content types and viewing scenarios. For example, when in power consumption reduction mode, the system adjusts parameters such as color depth, sharpness, and contrast differently based on the type of content being displayed, thereby maintaining acceptable image quality while reducing overall power consumption
Solution Approach 2:
The system changes multiple image quality parameters simultaneously (color space, bit depth, processing algorithms) to achieve an optimal balance between power consumption and image quality. By coordinating changes in multiple parameters rather than simply reducing brightness, the system maintains visual quality while reducing energy usage
3Use of energy by moving object
If multiple image quality processing elements are adjusted to reduce power consumption, then power consumption is reduced, but the complexity of control increases
Solution Approach 1:
The image quality processing system is divided into multiple independent processing elements (color space conversion, bit depth adjustment, sharpness enhancement, noise reduction, etc.). Each element can be independently controlled and adjusted, allowing the system to selectively activate or deactivate specific processing stages based on power consumption requirements without having to manage the entire processing chain as a single complex unit
