A method for patching up thin-film transistor (TFT) circuit patterns on a
display panel comprises the following steps. Firstly, a mask having an
opening is placed above the display panel and the opening corresponds to
the location of the cracks of the circuits on the display panel.
Subsequently, a plasma sputtering procedure is performed to deposit a
metal thin film through the opening of the mask on the display panel so
as to connect the broken circuits. When the metal thin film is covered on
a plurality of the circuits, a laser cut-out procedure is performed to
cut apart the metal thin film on the plurality of the circuits so as to
prevent the different circuits from short circuits.
