Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Micro LED splicing display screens experience visible image sticking and reduced luminous efficiency due to regional temperature differences when displaying gray-scale images for extended periods.
Innovation Solution
A display method that samples frames of image data and compensates the gray scale of each frame by determining initial compensation data, acquiring and filtering temperature influence data, and applying a gray-scale compensation coefficient to achieve consistent image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If gray-scale images are displayed on Micro LED splicing display screen for extended periods, then the display function is maintained, but regional temperature differences occur causing visible image sticking and reduced luminous efficiency
Solution Approach 1:
The patent applies preliminary action by pre-calculating and pre-storing compensation data for different gray-scale values and temperature conditions. Before actual display, the system builds a compensation data table that maps temperature differences to required gray-scale adjustments. During operation, this pre-prepared data is directly applied to compensate for temperature-induced luminance variations, preventing image sticking before it occurs rather than correcting it afterward.
Solution Approach 2:
The patent implements feedback by continuously monitoring the temperature difference across display regions and using this information to dynamically adjust the gray-scale compensation. The system measures actual temperature variations, compares them against reference values, and applies corrective gray-scale adjustments based on the measured deviations. This closed-loop feedback mechanism ensures that compensation remains accurate even as operating conditions change over time.
2Manufacturing precision
If gray-scale compensation is applied to reduce image sticking, then display uniformity is improved, but additional processing steps are required
Solution Approach 1:
The patent reduces processing complexity during operation by performing extensive calculations in advance. The compensation data table is pre-built containing all necessary adjustment values for different gray-scale levels and temperature conditions. During actual display, the system simply looks up pre-calculated values in the table and applies them, avoiding the need for complex real-time calculations and reducing processing steps while maintaining high display uniformity.
