Abstract

Impressive advances are being made in the field of display metrology, as illustrated in standards such as the Video Electronics Standards Association's Flat Panel Display Measurement standard, but issues remain regarding thetechnology-dependent response of displays to large-scale signal errors such as noise-induced errors on the signal and control lines. The NIST Display Interface Testbed can be used in conjunction with a graphics controller, test generator, or other standard signal source, to inject a user-specified controlled sequenceof errors into the interface of a display under test, permitting observation and measurement of the response of the display. In addition to its function as an interface tester, the Testbed effectively serves as a non-intrusive probe into the operation of the display. The programmed control structure of theTestbed permits the convenience of automated test sequences. Planned for 1999 is the development of a feedback mechanism which allows the test stimulus to be modified in real time, as a function of measurement results and user commands.
