Abstract
With the discoveries and inventions of modern display and digital processing technologies, the contemporary paradigm of displaying and demonstrating information has shifted from those from just a few decades ago. Cold cathode display is one of the most widely used and superior display technologies from 50 years ago, which is also being called 'nixie tube'; however, with the semiconductor-based display development and cathode-ray tube-based monitor during the late 1900s, cold cathode displays rapidly disappeared from the market and ever since then, manufactures all over the world never paid attention back to the cold cathode display. In this thesis, the cold cathode display technology will be reexamined by exploring the ideas and works made possible by combining the cold cathode display with modern digital circuits and digital signal processing technology. This thesis will be concluded by designing a unique piece of visual art --- An audio spectrum visualizer based on IN-13 cold cathode display tubes from World War II manufactured in the USSR as a demonstration and investigation of modern utilization of cold cathode display technology.
