Display driver module and mounting structure therefor

摘要

A low-cost display driver module is disclosed that shortens the process for connecting an integrated circuit chip (12) and a wiring pattern on a flexible wiring (11) and uses a metal chassis (21) on a display panel as a radiator. In this display driver module, an integrated circuit chip (12) with bump electrodes (18) on it is joined with pressure applied by the use of an anisotropic conductive film (19), an anisotropic conductive paste, a non-conductive resin paste, or a non-conductive resin film and the back of the integrated circuit chip is adhered to a metal chassis on a display panel by the use of an integrated-circuit chip adhesive (20). As a result, the metal chassis can be used as a radiator for the integrated circuit chip. Batch bonding will enable to shorten time for the connection process and to cut down the cost of installations. Furthermore, a radiator is unnecessary, resulting in a low-cost display driver module.
