AN LCD DISPLAY ASSEMBLY

By Steven P. Kopish and Ronald E. Petersen

The assembly provides for the positioning and retention of multiple elements in a compact and rug ged arrangement.

   A pair of elastomeric connector strips (I) of the type sold commercially as "Zebra"TM are inserted into an LCD bezel (2). Two contact heater clips (3) are attached to the edge of a heater glass (4) which has a conductive coating on the top surface. The heater glass subassembly is then inserted into the LCD bezel
(2) which has a stepped groove for retaining and positioning the heater glass (4) and contact heater clips
(3). The LCD (5) is then placed in a second stepped groove in the bezel (2) which both retains and positions the display. The combined elements are now attached to a PC board (6) by a clamp (7) on each side of the bezel (2) by means of six screws (8) (five shown) which are positioned by the back side of the PC board (6) into the LCD clamps(7).

   It is to be noted that the projecting fingers (7') of the clamp (7) have a rounded surface which contacts the glass face of the LCD (5). The separation of the fingers and the rounded surface are very critical in the distribution of forces on the face of the LCD (5) in order to prevent breakage of the LCD and to provide the proper loading on the connector strips (1) and heater clips (3) in order for the display to function properly over a wide range of environmental conditions.
