Display Panel Compensation Data for Regional Color Uniformity

Solution Overview

Problem

Existing display technologies face issues with color inconsistency and distortion due to differences in panel technology, leading to inaccurate color representation across multiple displays.

Innovation Solution

A method and system for generating compensation data and compensating display panels by acquiring optical data from different areas, applying compensation rules to generate and apply compensation data to improve color accuracy, using a controller and memory to store and invoke compensation data for display panels with varying area sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a single high-accuracy compensation rule is applied to the entire display panel, then color accuracy in the first area is improved, but the processing complexity and time increase significantly

Engineering Contradiction:

Improvecolor accuracyVSAvoidcompensation processing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The display panel is divided into multiple areas (first area and second area) with different compensation accuracy requirements. The first area receives high-accuracy compensation while the second area receives standard compensation, reducing overall processing time while maintaining color accuracy where most needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different compensation accuracy levels are applied to different regions of the display panel based on their specific requirements. The first area (typically center region) receives higher accuracy compensation while the second area (peripheral regions) receives standard compensation, optimizing resource allocation.

Inventive Principle:

Principle #3Local quality

2Stability of the object's composition

If compensation data is generated for the entire display panel with uniform high accuracy, then color consistency across the panel is improved, but the data processing complexity and storage requirements increase

Engineering Contradiction:

Improvecolor consistencyVSAvoidcompensation data processing complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The compensation data structure is segmented into different accuracy levels corresponding to different display areas. This reduces the overall complexity of compensation data processing while maintaining color consistency through multi-level compensation strategies.

Inventive Principle:

AI summary

A method for generating compensation data, which is applied to a display panel including a first area having a smaller size and a second area having a larger size. The method includes acquiring standard optical data of the display panel corresponding to one or more standard pictures, and first actual optical data of the first area corresponding to the one or more standard pictures; generating corresponding first compensation data according to a first compensation rule, the standard optical data, and the first actual optical data; acquiring second actual optical data of the second area in the display panel compensated by the first compensation data corresponding to the one or more standard pictures; generating corresponding second compensation data according to a second compensation rule, the standard optical data, and the second actual optical data, a compensation accuracy of the second compensation rule being less than that of the first compensation rule.
