Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smartphone display technologies cannot dynamically control color or white balance, leading to suboptimal image quality under varying ambient light conditions, which results in increased power consumption and noise emission.
Innovation Solution
A color control method that acquires ambient light color temperature information, calculates suitable color parameters, and adjusts the display accordingly, using a camera's AWB or ISP function, and also acquires brightness information to adjust both color and brightness parameters for optimal image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If display parameters are tuned optimized against the worst condition, then reliability is improved, but image quality in other conditions deteriorates and power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of display parameters (brightness, color temperature, gamma) based on real-time ambient light detection. The system transitions from static worst-case optimization to dynamic adaptation, continuously adjusting parameters according to actual environmental conditions, thereby improving image quality across varying conditions while reducing unnecessary power consumption.
Solution Approach 2:
The system changes multiple display parameters simultaneously based on ambient light conditions: brightness level, color temperature, and gamma values. By adjusting these parameters dynamically rather than fixing them for worst-case scenarios, the system achieves better image quality with lower power consumption in normal conditions.
2Reliability
If display parameters are tuned optimized against the worst condition, then reliability is improved, but image quality in other conditions deteriorates
Solution Approach 1:
The system dynamically adapts display parameters to match ambient light conditions, transitioning from a single fixed parameter set to multiple condition-specific parameter sets. This enables the display to maintain optimal image quality across diverse lighting environments including sunlight, indoor lighting, and dark conditions.
Solution Approach 2:
The patent adjusts multiple display parameters (brightness, color temperature, gamma) based on detected ambient light characteristics. By changing these parameters according to environmental conditions, the system achieves versatile image quality adaptation rather than relying on a single worst-case optimized configuration.
3Reliability
If display brightness is increased to improve image quality in all conditions, then image quality is improved, but power consumption and noise emission increase
Solution Approach 1:
The system adjusts display parameters dynamically based on ambient light conditions. In bright environments, the display can use lower brightness levels with optimized color temperature and gamma settings, while in dark environments, higher brightness is applied only when necessary. This selective parameter adjustment maintains image quality while reducing overall power consumption and associated noise emission.
