Then, when all of the plurality of gate TCP 114 is press-bonded to the ACF 123 attached on the gate pad portion 125 of the liquid crystal panel 102, the second stage 162 is driven by a driver (not shown). It is rotated as shown in FIG. As a result, the data pad portion 121 of the liquid crystal panel 102 seated on the second stage 162 faces the gate / data TCP pressing portion 154.

Accordingly, the plurality of gate / data TCP attachment pads 158 suck the data TCP 110 supplied from the third data TCP supply unit 152 by the rotation of the second index 156, and the second index 156. ACF attached to the data pad portion 121 of the liquid crystal panel 102 after being positioned on the liquid crystal panel 102 by the rotation of the < RTI ID = 0.0 > Press-fit onto 123. At this time, the gate / data TCP pressing unit 126 presses the remaining data TCP 110 among the plurality of data TCP 110 onto the ACF 123 attached to the data pad 121 of the liquid crystal panel 102. You are good. In one example, the gate / data TCP pressing unit 126 presses two data TCPs 110 on the ACF 123 attached to the data pad portion 121 of the liquid crystal panel 102. The liquid crystal panel 102 to which the remaining data TCP 110 is attached among the plurality of gate TCPs 114 and the plurality of data TCPs 110 is transferred to the main compression unit 128 by the transfer device 134.

On the other hand, in each of the data TCP pressing unit 124 and the gate / data TCP pressing unit 126, the number of TCPs 110 and 114 attached to the liquid crystal panel 102 is set to be the same.

The main compression unit 128 presses a plurality of data TCPs 110 pressed on the data pad portion 121 of the liquid crystal panel 102 transferred by the transfer device 134 to a predetermined temperature and pressure to form a liquid crystal. While fully adhering to the data pad portion 121 of the panel 102, the plurality of gate TCPs 114 pressed against the gate pad portion 125 of the liquid crystal panel 102 are pressed to a predetermined temperature and pressure. It is completely adhered to the gate pad portion 125 of the liquid crystal panel 102. As such, the liquid crystal panel 102 in which the plurality of data TCPs 110 and the plurality of gates TCP 114 are completely bonded is transferred to the alignment check unit 130 by the transfer device 134.

The alignment check unit 130 is an alignment mark (not shown) of the plurality of data TCPs 110 and the alignment mark of the data pad unit 121 completely adhered to the data pad unit 121 of the liquid crystal panel 102. The misalignment between the data pads 121 and the data TCP 110 is checked by checking the misalignment between (not shown).

In addition, the alignment check unit 130 aligns the alignment marks (not shown) of the plurality of gate TCPs 114 and the gate pads 125 that are completely adhered to the gate pads 125 of the liquid crystal panel 102. The misalignment between the in marks (not shown) is checked to check the connection failure between the gate pad 125 and the gate TCP 114. The alignment check-completed liquid crystal panel 102 is transferred to the unloading device 136 by the transfer device 134.

The unloading device 136 serves to unload the liquid crystal panel 102 supplied from the alignment check unit 130 to the outside by the transfer device 134.

As described above, the apparatus and method for manufacturing a flat panel display according to an exemplary embodiment of the present invention press-bonds some of the data TCP 110 of the plurality of data TCP 110 in the data TCP pressing unit 124, and then the gate / The data TCP pressing unit 126 presses the plurality of gate TCPs 114 and presses the remaining data TCP 110 among the plurality of data TCPs 110. Accordingly, the present invention shortens the time for pressing and attaching a plurality of data TCPs 110 to the data pad portion 121 of the liquid crystal panel 102, which is relatively larger than that of the gate TCPs 114. It can be shortened. Therefore, the present invention can improve the productivity of the liquid crystal display device.

Meanwhile, the apparatus for manufacturing a flat panel display device according to an exemplary embodiment of the present invention has been described with reference to the liquid crystal panel 102 as an example. However, in addition to the liquid crystal panel 102, a flat panel display device such as a plasma display panel and a light emitting display device may be used. By pressing the plurality of data TCPs 110 and the plurality of gates TCP 114 on the display panel as described above, the time of the TCP attaching process can be reduced.

As described above, the apparatus and method for manufacturing a flat panel display according to an exemplary embodiment of the present invention display a plurality of gate tape carrier packages after pressing some of the data tape carrier packages of the plurality of data tape carrier packages onto the display panel. The pressing process of the tape carrier package can be reduced by pressing the panel carrier and pressing the remaining data tape carrier package of the plurality of data tape carrier packages to the display panel. Accordingly, the present invention can improve the productivity of the flat panel display by reducing the time for attaching the tape carrier package.
