A heatable element is configured to apply sufficient energy density to contaminants in an internal ambient atmosphere with in a sealable housing to drive a reaction that inactivates the contaminants.

A liquid crystal device and the backlight module thereof are disclosed. The backlight module includes a back plate, at least one optical film, a plurality of optical fibers, and a reflector. The optical fibers are arranged to configure at least one light bar of the backlight module. The optical film and the back plate are spaced apart and opposite to each other to define a chamber for the light beams to be transmitted.
