Abstract:
An electronic device having an indication member for determining liquid exposure in an electronic device is disclosed. The indication member may include ink and a layer covering the ink. The layer may include a liquid-permeable layer that allows liquid to pass through the layer and contact the ink. In this regard, at least some of the ink may rise through the layer and to a top surface of the indication member. Although the ink may be exposed at the top surface, in some cases, the ink is visible or detectable when exposed to light from an ultraviolet light source. Also, the top surface may include a pattern or other indicia that is also visible or detectable when exposed to the light source. When the indication member is exposed to liquid, the pattern may be altered or disturbed in a location corresponding to an exposed portion of the indication member.
