Paper 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. However, issues remain regarding the technology-dependent response of display to large-scale signal eros such as noise-induced errors on the data 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 sequence of 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 the Testbed permits the convenience of automated test sequences. Development of a feedback mechanisms which allows the test stimulus to be modified in real time, as a function of measurement result and user commands is planned for 1999.
