Multi-Display Luminance Control via Centralized Standardization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-display systems, conventional techniques for adjusting luminance levels to address temperature abnormalities lead to variations among display devices, impairing the overall visibility by not uniformly controlling luminance across all devices.
Innovation Solution
A display control device that centrally manages multiple display devices by obtaining and standardizing luminance setting values across all devices, ensuring uniform luminance levels are maintained even when temperature abnormalities occur in one or more devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If luminance level of a display device is reduced to lower internal temperature, then temperature abnormality is prevented, but luminance variation occurs among display devices in multi display system
Solution Approach 1:
The patent merges the temperature control decisions of multiple display devices into a single centralized control system. When temperature abnormality is detected in any display device, the control device uniformly adjusts the luminance levels of all display devices based on the detected temperature information, ensuring consistent luminance across the multi-display system while preventing temperature abnormalities.
Solution Approach 2:
The patent segments the temperature management function from individual display devices and assigns it to a dedicated control device. The control device receives temperature information from each display device separately, processes this information centrally, and generates unified luminance adjustment commands for all devices, achieving both temperature control and luminance consistency.
2Reliability
If luminance level is adjusted individually in each display device, then temperature abnormality is addressed, but visibility of entire multi display system is impaired
Solution Approach 1:
The control device implements a feedback mechanism where temperature information from each display device is continuously monitored and fed back to the control device. Based on this feedback, the control device calculates appropriate luminance adjustment values and sends control commands back to all display devices, creating a closed-loop system that maintains both temperature safety and visual consistency.
Solution Approach 2:
The control device acts as an intermediary between individual display devices and the user/system. It receives temperature data from display devices, processes this information, and generates unified luminance control commands. This intermediary role ensures that temperature management decisions are made centrally while maintaining consistent visual output across all devices.
