Document Type and Number:
Japanese Patent JP2005505066
Kind Code:
A
Abstract:
Chip card processor P and display controller C of chip card 1 with a display are realized in single chip 5 and the chip 5 is disposed on same substrate 4 on which display 2 is built up. This eliminates the need for connecting leads and contactings between the display controller and the processor chip. Display 2 and chip 5 form one mechanical unit and it is unnecessary to install processor chip P. Preferably, display substrate 4 extends with processor chip P, or at least with conductive paths leading to processor chip P, under contact pad 3 of chip card 1.
