Abstract
A vacuum fluorescent iconographic display ( ) operable to communicate the operating conditions of a low temperature refrigeration unit ( ), with the display ( ) using only intuitively recognizable pictorial iconic elements ( ), numeric elements ( ), and recognized symbolic elements ( ) to convey the information. The iconic elements ( ) unambiguously represent the various operating conditions without reliance on legends or other conventional written or spoken language, thereby avoiding translation or interpretation mistakes due to the use of such a conventional language in a possibly international product or multi-lingual situation. The iconic elements ( ) may also be used in diagnostic applications by lighting, for example, in combination with the numeric elements ( ) to communicate quantitative diagnostic measurements of the subsystem represented by the icon. Because it employs vacuum fluorescence technology, the iconographic display ( ) is bright and visible from a large range of viewing angles, further aiding recognition of the displayed information.
