ABSTRACT:
A method and apparatus are described for testing a line screen CRT for misregistration between its electron beam and the beam's phosphor stripe targets. The test method includes sensing light output at a plurality of test areas on the CRT screen as the electron beam is stepped across its phosphor targets. The maximum and minimum light outputs of each test area, and the beam locations at which the maximum and minimum light outputs were obtained, are used to compute the degree of misregistration for each test area.
