STAX Elastomeric
Connectors for COG LCDs
Features
Easily customized.
Connects display glass or flex
circuit to PCB.
Inhibits movement of the con-
tact interface during vibration.
Stable electrical performance
over a wide working range of
deflection.
Can accommodate glass-to-
board separations of as little as
0.25 mm.
Applications engineering sup-
port from Tyco Electronics to
incorporate STAX elastomeric
connectors into your product.
Support includes board layout,
slot definition, alignment and
compression.
In-molded sub assemblies can
be created to combine LCD
connector with backlighting
connection while providing
orientation features.

Low resistance STAX elastomeric connectors are the best means of connecting to Chip-on-Glass
and other types of LCD modules. Gold STAX and STAX LD elastomeric connectors are easily
customized without the tooling charges and lead times typically found with stamped contacts
and molded insulators. They can be retained in a slot incorporated into the light guide that allows
for automatic placement of the light guide subassembly.
STAX connectors provide a gasket-like contact interface to the
ITO traces thereby sealing the interface from the environment.
At the same time, the compliant sealing properties of the silicone
elastomeric connector maintain intimate conformal contact to
the ITO surface.
STAX connectors have proven reliability in COG LCD displays for cell phone units – numbering in
the hundreds of millions.
