Solution Overview

Problem

Display panels, especially when multiple panels are connected or flexible, often experience output position distortion due to mismatches in color or position, leading to image distortion observed by users, which existing technologies fail to adequately address.

Innovation Solution

An artificial intelligence apparatus and method that output position calibration images, capture images of the display panels using a camera, calculate output position offsets, and determine calibration values to correct for distortions, ensuring accurate image display without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple display panels are connected to form a large display, then the display area is increased, but output position distortion occurs between panels

Engineering Contradiction:

Improvedisplay areaVSAvoidoutput position alignment

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

The system divides the large display into multiple individual display panels, each with its own calibration parameters. The calibration is performed panel-by-panel using a camera to capture the output position of test patterns, allowing independent adjustment of each panel's output position to eliminate distortion while maintaining the overall large display area.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If display panels are used without calibration, then the device complexity is reduced, but output position distortion occurs in the displayed image

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The system performs self-calibration by automatically capturing images of the display output using a camera, calculating output position offsets through image processing, and generating calibration values without requiring manual intervention. This automated self-service approach maintains simplicity while achieving high display accuracy.

Inventive Principle:

Principle #25Self-service

3Measurement precision

If manual calibration is performed, then the calibration accuracy can be adjusted, but the maintenance cost and effort increase

Engineering Contradiction:

AI summary

An artificial intelligence apparatus for calibrating an output position of a display panel according to an embodiment includes a camera configured to capture an image displayed by the display panel; and a processor configured to: transmit a signal for outputting a position reference image to the display panel, receive, via the camera, a captured image for the display panel, calculate an output position offset for the display panel in a predetermined unit based on the position reference image and the captured image, determine an output position calibration value for the display panel using the calculated output position offset, and transmit the determined output position calibration value to the display panel.
