Abstract : The patent discloses a pure fluid display. A thermally sensitive layer whose optical characteristics are a function of temperature is subjected to the impingement of a plurality of fluid sources whose temperature is different from the ambient temperature of the sensitive layer. This produces a temperature pattern on the surface of the sensitive layer which in turn creases a color pattern to correspond to the temperature pattern. The fluid sources, which may comprise the outputs of a plurality of fluid amplifiers, are generally arranged in the form of a two-dimensional array parallel to the surface of the sensitive layer. Coextensive supporting members having low-thermal capacity are provided on both sides of the sensitive layer, the first supporting member being opaque and the second being transparent on the viewing side. A temperature control system is provided to maintain the sensitive layer within a predetermined temperature range.
