ABSTRACT:
A liquid crystal display (LCD) package (10) is made by creating an indium/tin oxide electrode (64) on the surface of a flexible substrate (60). The electrode is connected to conductive vias (68) in the flexible substrate by conductive runners (66) that are also indium/tin oxide with an overlayer of copper. The indium/tin oxide is typically sputtered, and the copper is sputtered or plated on selected portions of the runners. The conductive vias are further connected to a circuitry pattern (62) on an opposite side of the flexible substrate. A display driver (70) is attached to the circuitry pattern to drive the LCD (5). A second substrate (80), also with a film electrode (82) on it, is arranged in mutually opposing planar relationship to the flexible substrate in order to form a liquid crystal display. A liquid crystal material (86) is then filled in the gap between the two substrates creating an LCD module (10). The LCD module can be folded about a portion (72) of the flexible substrate so that the display driver circuit is directly underneath the film electrode. An adhesive bonding agent (77) is used to retain the flexible substrate in the folded position.
