ABSTRACT:
A weather station has an MCU for evaluating weather information relating to an atmospheric parameter, a sensor for sensing the parameter for subsequent processing by the MCU, and an LCD display. The LCD display has a multi-layered structure including front and rear glass plates, liquid crystal material located between the plates in a pattern having a number of parts, a foremost transmissive polarizer, and a transflective polarizer behind the rear glass plate. There is also a color backing behind the rear polarizer, which has a number of regions in different colors and cover the liquid crystal pattern parts, so that the color regions are selectively revealed through the parts of the pattern as the parts of the pattern of the liquid crystal material are activated, thereby displaying the weather information in color.
