The OPTO 9260 Image Verification System from ITF-Engineering, is a unique system designed specifically for the fully automated, high speed testing of Liquid Crystal and LED displays. Suitable for both Dot Matrix and Multiple Segment displays with symbol recognition and verification, the system allows the accurate testing of any type and size of display. The levels of accuracy and repeatability achieved with the OPTO 9260 cannot be guaranteed with the human eye. The system is especially well suited for the quality control of incoming goods and for the production testing of products with built in displays such as telephones, car radios, pagers, mobile phones, etc.

The OPTO 9260 consists of a CPU ‘Frame Grabber’ full length card which can be inserted into any IBM Compatible PC. Up to 3 CCD cameras ( 12 with the use of an optional Multiplexer board ) can be connected.
The images received through the cameras are digitised and can then be displayed on a Video Monitor supplied with the system for learning in and testing purposes.

The menu structured software for the OPTO 9260 allows the programming and ‘learning in’ of new displays to be tested. A combination of dot matrix blocks, segments, letters, and symbols can be easily learnt in and saved on the host PC. This data is then used as reference information for the following tests. Positioning information is also learnt in using reference points on the display to correct for any mechanical variations in the absolute positions of the displays under test.

The test sequences can be run independently from the DOS platform with the software provided, on a separate computer activated via commands sent through the serial interface or by integrating program library modules ( Microsoft C / C++ ) directly into the customers existing application.

The OPTO 9260 has also been successfully utilised to verify the presence of components on freshly populated printed circuit boards. This time required for this type of testing is less than two seconds per board and ensures that all components have been mounted correctly thereby saving expensive repair procedures further on down the line.
