Abstract:
A method for fabricating a repairable TFT-LCD assembly comprising the steps of:providing a LCD substrate equipped with conductive pads on a top surface, bonding a first anisotropic conductive film (ACF) to the top surface of said LCD substrate, positioning a separation tape on top of said first ACF, said separation tape being formed of an electrically insulating material and provided with a multiplicity of apertures at locations corresponding to said conductive pads on said LCD substrate, each of said multiplicity of apertures is filled with a conductive metal, bonding a second ACF to a top surface of said separation tape, positioning an IC chip on top of said second ACF and aligning a multiplicity of bond pads on said IC chip to said conductive pads on said LCD substrate, and pressing said IC chip, said second ACF, said separation tape, said first ACF and said LCD substrate together under heat for a length of time sufficient to establish electrical communications between said IC chip and said LCD substrate through the conductive pads and the bond pads.
