Backlight Calibration with Automatic Type Detection for Color Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The misusage of backlight parameters during calibration leads to color washout in LCD display modules due to the difference in luminous efficacy between traditional and mini-LED backlights, as manufacturers often produce both types simultaneously.
Innovation Solution
A detector is used to determine the backlight type by detecting parameters such as bright area proportion, brightness, temperature, and brightness density, and then performs calibration using specific parameters tailored to the identified type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional backlight calibration parameters are used in mini-LED backlight display modules, then the calibration process is simplified, but color washout occurs and display quality deteriorates
Solution Approach 1:
The patent applies parameter changes by detecting backlight parameters (brightness, temperature, luminous efficacy) and adjusting calibration parameters dynamically based on the detected backlight type. Instead of using fixed traditional calibration parameters for all backlights, the system changes parameters adaptively - using mini-LED specific calibration parameters when mini-LED backlight is detected, and traditional parameters when conventional backlight is detected, thereby preventing color washout while maintaining calibration effectiveness
Solution Approach 2:
The patent introduces an intermediary detection mechanism that identifies the backlight type before calibration is performed. This intermediary step (detecting luminous efficacy, brightness, and temperature characteristics) acts as a mediator between the calibration system and the backlight source, enabling the system to select appropriate calibration parameters and avoid direct misapplication of traditional parameters to mini-LED backlights
2Manufacturing precision
If backlight type detection and adaptive calibration is implemented, then display quality is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by enabling the calibration system to automatically detect the backlight type and select appropriate calibration parameters without manual intervention. The system autonomously measures backlight characteristics (luminous efficacy, brightness, temperature), identifies whether it's a mini-LED or traditional backlight, and automatically applies the correct calibration parameters, eliminating the need for manual configuration and reducing operational complexity despite the enhanced functionality
Solution Approach 2:
The patent applies universality by designing a calibration system that can handle multiple backlight types (both traditional and mini-LED) through a single unified detection and adaptive calibration mechanism. The system performs multiple functions - detecting backlight type, measuring parameters, identifying the appropriate calibration set, and executing calibration - all through one integrated process, avoiding the need for separate calibration systems for different backlight types
