A LIQUID CRYSTAL DISPLAY ASSEMBLY FOR USE WITH ELECTRONIC DEVICES IS DISCLOSED. A LIQUID CRYSTAL DISPLAY (8) IS ADHERED TO AN ELECTRO LUMINESCENT FILM (6), WHICH IS, IN TURN, ADHERED TO A CIRCUIT BOARD (4). A TAPE CARRIER PACKAGE (3) INCLUDING A LIQUID CRYSTAL DISPLAY DRIVER CIRCUIT (2) AND ELECTRICAL CIRCUITRY FOR ESTABLISHING ELECTRICAL CONTACTS BETWEEN THE CIRCUIT BOARD (4) AND THE LIQUID CRYSTAL DISPLAY (8) IS SECURED TO THE CIRCUIT BOARD (4) AND THE LIQUID CRYSTAL DISPLAY (8) TO DEFINE A SUB-ASSEMBLY. THE SUB-ASSEMBLY IS THEN SECURED IN A CARRIER (10). ELECTRICAL CONNECTIONS BETWEEN THE LIQUID CRYSTAL DISPLAY (8) AND THE CIRCUIT BOARD (4) OF THE ELECTRONIC DEVICE MAY BE ESTABLISHED USING ELECTRICALLY CONDUCTIVE SPRINGS (1).
