Electro-optical Display Inspection System
A PC-based machine vision system generates after appropriate created test samples a notification through commands on the testing display. The camera, which is attached to the system, gathers the displayed sample and passes it to the image processing system. The incoming signals are compared to the predefined sample and analyzed within the shortest length of time. The system allows the control of brightness, color, homogeneity, contrast and pixel faults through the LCD/LED-display-inspection in the case of dotmatrix as well as 7-/14- segment notifications.
During the symbol inspection, printed or lasered symbols are checked for 100% completeness, right positioning (x-, y-rotation) and symbol peculiarity. Furthermore, also tasks like fall of keys can be realized reliably.
