CDIM
Curved Display Inspection Machine
Key Features
Standalone inspection system for curved displays, supporting multiple product types without major hardware changes.
Linear camera system for curved-to-flat image translation and accurate defect detection.
Deep learning algorithms for adaptive defect detection of a variety of error types.
Vision App (Proprietary)
HIGHLIGHTS
- Trigger mode: manual or automatic (configurable in-app).
- MSA mode: configurable for quality testing.
- Local database with story mode: for image review.
- Data export to CSV: for external analysis and integration.
- Live camera mode: for real-time monitoring.
- Station/line map render: for operator guidance.
- Multiple test modes: for different inspection needs (display defects, image view, frame defects).
SETTINGS AND DYNAMYC RECIPES
- Adjustable camera parameters: exposure time [ms], frame rate [fps].
- Image reference: configurable to test products at different positions (requires adequate camera range).
- Test model creation: defining criteria to locate features (e.g. screw positions, alphanumeric markings) and verify part placement (the configurable element is the search criteria; the test adapts accordingly).

Overview
The CDIM – Curved Display Inspection Machine is a standalone inspection system for curved displays. At the core of the CDIM is a linear camera system that translates curved images into flat representations, enabling precise and consistent inspection across the entire surface of the display. This approach ensures that no area is left uninspected and that all data collected can be processed with the same accuracy as a flat panel.
The system is powered by deep-learning algorithms capable of learning the expected image profile and identifying a wide range of defect types, from dead pixels or display errors (when powered on) to curvature deviations, surface defects, or frame irregularities (when powered off).
The machine’s overhead-mounted robot provides flexibility for handling multiple product types, allowing quick reconfiguration by simply changing the nest and/or the gripper, and updating the robot program.
Operation and test configuration are managed through the Controlar Vision App, a proprietary and configurable interface that allows users to set up, monitor, and customize inspection tests quickly and flexibly.
Product Configuration
This station is composed of:
- Linear camera system with dedicated lighting.
- Overhead-mounted robot with absolute encoder.
- Customizable nests for different display types.
- Deep learning inspection software.
- Proprietary vision app.
- Operator monitor displaying the robot’s live image feed.
Main Applications
The CDIM is adaptable to different display geometries and easy to integrate into both laboratory and production environments.
Designed as a standalone, production-ready station, the CDIM can be easily deployed and reconfigured without major hardware changes.
Its combination of precise mechanical architecture, adaptive vision technology, and intelligent software makes it a robust and scalable solution for ensuring the quality and reliability of curved displays, helping manufacturers maintain high standards while keeping inspection fast, flexible, and cost-effective.
