Parallel Optical Adjustment for OLED Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical adjustment methods for OLED display panels, such as gamma tuning, are time-consuming, affecting manufacture efficiency and potentially compromising image quality due to the large number of debugging points required.
Innovation Solution
An optical adjustment method that displays N groups of testing images sequentially on the display panel, with each group containing M images distributed across different regions, allowing simultaneous detection and adjustment of optical parameters by an optical detection unit to reduce the number of debugging points from n*m to n*1, thereby reducing tuning time while ensuring image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional serial mode is adopted for gamma tuning with n groups of registers and m grayscale binding points, then the image quality can be adjusted at multiple debugging points, but the tuning time becomes extremely long (about 98 seconds)
Solution Approach 1:
The patent divides the display panel into multiple display regions and assigns different debugging points to different regions. By performing parallel detection and adjustment on multiple regions simultaneously, the patent reduces the sequential tuning time while maintaining comprehensive image quality coverage across all regions.
Solution Approach 2:
The patent combines multiple detection operations into a single parallel process. Instead of detecting and adjusting each debugging point sequentially, the system detects multiple debugging points across different regions simultaneously and merges the adjustment operations to reduce overall tuning time.
2Productivity
If an improved algorithm policy is used to reduce tuning time to about 72 seconds, then the manufacturing efficiency improves, but the image quality is adversely affected to some extent
Solution Approach 1:
The patent segments the debugging process into multiple parallel operations across different display regions. This allows comprehensive image quality adjustment at multiple points without proportionally increasing total time, as regions are adjusted simultaneously rather than sequentially.
Solution Approach 2:
The patent implements a dynamic parallel adjustment strategy where multiple debugging points are adjusted simultaneously based on real-time detection results. This dynamic approach maintains image quality by adapting adjustments to actual measured values while reducing total tuning time through parallel execution.
3Productivity
If a further-improved algorithm policy is used to reduce tuning time to about 25 seconds, then the manufacturing efficiency greatly improves, but there is a risk of NG progressive image quality due to lack of characteristic dynamic matching
Solution Approach 1:
The patent divides the display panel into multiple regions with multiple debugging points distributed across them. By performing parallel detection and adjustment on these segmented regions, the system achieves fast tuning without sacrificing image quality stability, as each region is independently optimized while maintaining overall consistency.
Solution Approach 2:
The patent implements a feedback mechanism where detection results from multiple debugging points are used to guide parallel adjustment operations. This feedback loop ensures that adjustments are based on actual measured values, maintaining image quality stability while achieving fast tuning through parallel processing.
4Manufacturing precision
If the value of m is increased to meet image quality requirements, then more grayscale binding points are adjusted, but the tuning time for all algorithm policies is prolonged
Solution Approach 1:
The patent segments the multiple debugging points across different display regions and performs parallel detection and adjustment operations on these segments. This allows the system to handle a large number of grayscale binding points (high m value) without proportionally increasing total tuning time, as multiple points are adjusted simultaneously rather than sequentially.
Solution Approach 2:
The patent combines multiple detection and adjustment operations into parallel processes that execute simultaneously. By merging these operations across different regions and debugging points, the system maintains comprehensive image quality adjustment for numerous grayscale binding points while significantly reducing the cumulative time required.
