Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
OLED displays consume significantly more power when showing bright images compared to TFT-LCDs, particularly due to their power consumption being proportional to light intensity, leading to increased energy usage in applications with light backgrounds and dark foregrounds.
Innovation Solution
A power-saving display information converting system and method that employs a proxy server with a processor to receive and convert display information using a power-saving conversion model and power consumption model, reducing the power consumption of OLED displays by adjusting pixel brightness and color to minimize energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If display information is converted to reduce power consumption, then energy usage decreases, but display quality may deteriorate
Solution Approach 1:
The system dynamically adjusts display parameters including brightness levels, color saturation, and contrast ratios based on the power consumption model. By modifying these parameters adaptively, the system reduces power consumption while attempting to preserve acceptable display quality through controlled parameter transformation rather than complete image conversion.
Solution Approach 2:
The conversion process applies different processing strategies to different regions of the display content. Critical visual elements maintain higher quality standards while less important areas undergo more aggressive power-saving transformations. This localized approach ensures that power reduction does not uniformly degrade all display quality.
2Use of energy by moving object
If a proxy server is introduced to convert display information, then power consumption reduces, but system complexity increases
Solution Approach 1:
A proxy server is introduced as an intermediary component between the display content source and the OLED display device. This mediator performs power consumption calculations and applies conversion models to transform display information before it reaches the display, thereby reducing OLED power usage without requiring modifications to the display hardware itself.
Solution Approach 2:
The system incorporates a power consumption model that continuously monitors and evaluates the power usage characteristics of display content. This feedback mechanism allows the proxy server to dynamically adjust conversion strategies based on real-time power consumption data, optimizing the balance between power savings and display quality.
3Use of energy by moving object
If brightness is reduced to save power, then energy consumption decreases, but visibility and display effectiveness worsen
Solution Approach 1:
The system dynamically adjusts brightness levels based on multiple factors including ambient light conditions, display content characteristics, and user viewing patterns. Rather than applying a fixed brightness reduction, the system adaptively modulates illumination intensity to maintain visibility while minimizing power consumption through dynamic parameter adjustment.
Solution Approach 2:
The brightness adjustment operates in periodic cycles, alternating between higher brightness periods for critical information display and lower brightness periods for less important content. This periodic modulation allows the system to maintain acceptable visibility while reducing average power consumption over time.

AI summary
Display information to be displayed by a display device having a power consumption model is converted according to a power-saving conversion model and the power consumption model, such that the power consumption of the display device for displaying the converted display information is lower than that for displaying the original display information.
