Provided are a fluorescence conversion medium which comprises at least a fluorescent coloring matter and a binder resin and which can absorb light from a light emitter and can emit visible fluorescence, wherein fine particles containing the fluorescent coloring matter are dispersed in the binder resin; and a display device that comprises a light emitter and the fluorescence conversion medium. The housing has a mating surface and a mating space defined in the mating surface thereof for insertion of the plug. One or more sources of configuration data may respond to the requests, such as by providing configuration data to the testing mechanism. Each monitored variable may be allocated a vertical slice of the reference shape, such that the position of the corresponding icon when the variable is in the higher-interest state is laterally aligned with the position of the icon when the variable is in the lower-interest state. The second local bit line can be selectively coupled to the second global bit line based upon a second control input.
