Abstract
A display apparatus that includes a mask layer composed of transparent portions and opaque portions, the mask layer being superimposed over a pattern layer comprising light portions and dark portions. The mask layer can be moved relative to the pattern layer between a first position, whereby certain portions on the pattern layer are selectively obscured, and a second position whereby other portions on the pattern layer are selectively obscured. The mask layer can be moved relative to the second level by the movement of an actuating member coupled thereto as a function of ambient physical conditions. The ambient conditions may include, for example, temperature, pressure, humidity, acidity, voltage, fill level and the like.
