Display Quality Inspection
Display quality contributes heavily to the overall quality and end-user experience of smart devices. An automated display quality inspection method is important in e.g. incoming inspection of display modules, production testing of display modules, and production testing of final products.
OptoFidelity™ GoldenEye is a display quality inspection tool for checking the quality of high-resolution displays from wearables to even the largest TV screens. OptoFidelity™ GoldenEye is delivered either as a fully assembled cabinet construction, or it can also be integrated into existing test environments. It supports all machine vision matrix cameras, so you can select an optimal camera solution according to your needs. Distortion caused by camera and lens is corrected by full spatial calibration feature.
The GoldenEye solution utilize the years of machine vision experience and the image reconstruction method to make the inspection at a single pixel level. The system supports all machine vision matrix cameras, so one can select an optimal camera solution according to one’s needs. It even supports multicamera systems for larger screens or robot moving cameras for more challenging display concepts such as curved screens.
OptoFact: GoldenEye supports all machine vision matrix cameras.
OptoFidelity™ GoldenEye Test Coverage
Verify the quality of the display | Uniformity | Line & particle defects | Pixel defects | Brightness & contrast | MURA | LED hot spots | Light leakages | Color Measurement | Flicker Measurement
INTEGRATION WITH ROBOT PLATFORM
With OptoFidelity™ GoldenMov robotics, display inspection can be utilized with robot related tests e.g. force calibration, touch accuracy and linearity testing and Push Mura test to name few options.
OptoFidelity™ GoldenEye Benefits
Extensive defect coverage| Simple to set-up and use | Simplified analysis parameter settings | A sophisticated test results analysis algorithm guarantees fast test cycle time | Easily adjustable for different display sizes and resolutions | Clear defect visualization and reporting | Supports integration to robot systems and multicamera systems | Simple teaching method for new products | Possibility to re-run analysis for already tested displays. Display images and results of the earlier analysis parameters are stored in the database. Changes in analysis parameters can be re-run and compared to earlier test runs. | Optimized Smart Factories with data collection and usage of previously tested data
