Abstract:
A connector for display inspection of a liquid crystal display panel which comprises, as an assembly:(a) a circuit board having input electrode terminals and output electrode terminals provided on one surface of the circuit board and electrically connected together;(b) connecting lead wires each connected at one end to one of the output electrode terminals of the circuit board taking an arch-wise bent configuration, the other end being extended to a opposite side of the circuit board relative to the output electrode terminals;(c) a rigid covering body having a downwardly extended side portion and fixed to the circuit board to cover the connecting lead wires as a whole within a space between the circuit board and the covering body, a cavity or groove being formed in a downwardly facing end surface of the downwardly extended side portion;(d) an insulating cured elastomeric resin filling a space below the covering body to embed the connecting lead wires therein excepting end portions of the connecting lead wires not connected to the output electrode terminals to be exposed; and(e) a driver IC chip having electrode terminals in a substantially similar wiring pattern and arrangement pitch as delivery electrodes for display output signals in a glass substrate of the liquid crystal display panel to be inspected and adhesively bonded to a bottom surface of a cavity or groove formed in the downwardly facing end surface of the side portion of the covering body with intervention of an insulating elastomer sheet in such a fashion that, when the driver IC chip is brought to a position corresponding to a mounting position on the glass substrate, the exposed end portions of the connecting lead wires are on a display input signal delivery electrodes and the exposed end portions of the connecting lead wires and the electrode terminals of the driver IC chip are coplanar.
