Visual alarm for a communication module

摘要

An organic electroluminescent material is sealed within the outer housing of a portable radio telephone along with the control grids to cause the material to luminesce in a pixilated pattern. The pixels are controlled to generate a visual alarm which flashes a warning to a user as either a message or a flashing color of the housing or image. The visual alarm may be combined with audible and vibratory alarms within the mobile telephone.
