ABSTRACT:
Picture electrodes of an LCD semi-manufactured product in which normal addressing is not possible are scanned by means of an electron beam (7) in order to test the associated switching elements (13, 20). In a different type of LCD semi-manufactured product the quality of the switching elements (23, 24) can be monitored by means of irradiation with a laser beam (5).
