Elastomers are silicon strips of alternating conductors and insulators. These materials are generally soft and compliant and can be easily compressed between the Liquid Crystal Display and circuit board. Elastomers require a bezel to squeeze the display and circuit board together. This method will yield a higher conductor interconnection than pins, potentially less costly than pins, but requires a specialized compression bezel.
are attached to the display to allow the user to either mount the display in
a socket or solder it directly into a circuit board. From an end user
standpoint, pins are the easiest to use since there is no requirement for a
compression bezel or expensive heat seal bonding equipment.
are similar to flexible circuit boards with the difference being that the
interface tabs are made of a conductive hot melt adhesive. Generally,
particles such as carbon, gold, or silver are added to the adhesive to make
it conductive. The pads of the heat seal are aligned with the pads of the
display and a hot bar is brought down under pressure and the conductive
adhesive is melted and bonded to the display. The adhesive is allowed to
cool and an electrical bond is made with the display. This method is the
most cost effective for the higher volume applications, but due to the
expensive setup and equipment required in this process, Heat Seals are
used for lower volume / low interconnection density requirements..
