The image processing solution IQVision display control is a PC-based image processing system for optical quality inspection of LCD displays. Criteria such as fully formed elements, background colours, contrast ratios and edge sharpness of the display elements are checked up to the Sub-DOT control for colour displays. A combination with other applications is possible. With the multi-processor capable PC platform, inspections with up to 16 b/w and colour cameras are realized. The typical test speed is 1-10 test pieces/min.
The test tasks are taught-in by the user via a graphical user interface by selecting the relevant objects and features by mouse and then entering the parameters. A script programming also offers the possibility to define complicated test sequences. The customer-specific system interface equipment allows integration into a production line, data exchange with higher-level control systems and remote maintenance via remote access.
