Display Brightness Adjustment Using Ambient Light Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display brightness adjustment methods in information handling devices often result in unnecessary changes due to temporary light blocking events, leading to discomfort for users, as they fail to distinguish between actual ambient light level changes and temporary light level changes caused by obstructions.
Innovation Solution
A method that detects changes in light levels and receives data from other sources to determine if the change corresponds to an ambient light level change, allowing for precise adjustment of display brightness only when necessary, thereby preventing unwanted brightness adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If display brightness is automatically adjusted based on light sensor detection, then display visibility is improved, but unnecessary brightness changes occur due to temporary light blocking events
Solution Approach 1:
The system continuously monitors light levels and compares current readings with previous measurements to detect actual ambient light changes versus temporary blockings. By implementing feedback mechanisms that analyze light level patterns over time, the system can distinguish between genuine ambient light changes requiring brightness adjustment and temporary obstructions that should be ignored, thereby improving both display visibility and adjustment reliability.
2Reliability
If multiple sensors are deployed to distinguish ambient light changes from temporary blockings, then brightness adjustment accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The system divides the light detection function into multiple independent measurement components that can be implemented through software algorithms rather than additional physical sensors. By segmenting the detection logic into separate analysis stages (initial detection, pattern recognition, validation), the system achieves high reliability in distinguishing ambient light changes from temporary blockings using a single sensor, thereby avoiding increased device complexity and cost.

AI summary
One embodiment provides a method, including: detecting a change in light level; receiving, from at least one other source, data associated with an ambient light level; determining, using a processor, whether the change in light level corresponds to a change in the ambient light level; and adjusting, responsive to determining that the change in light level corresponds to the change in the ambient light level, a brightness level of a display operatively coupled to an information handling device.
