Abstract

A system for manufacturing a liquid crystal display includes a rotatable stage and a plurality of heads located on the rotatable stage. Each head is separated from each of its neighboring heads by a predetermined distance. The heads are enabled to rotate together with the rotatable stage in order to transport a tape carrier package (TCP). A first head retains the TCP and is located at a first position enabling the TCP to be detected. The first head is located at a second position enabling the first TCP to be pressed. The second position is different from the first position.

Claims (34)

1. A system for manufacturing a liquid crystal (LC) comprising:

a rotatable stage; and

a plurality of heads disposed on the rotatable stage, each head being separated from each of its neighboring heads by a predetermined distance, the heads being enabled to rotate together with the rotatable stage in order to transport a tape carrier package (TCP), a first head retaining the TCP and being disposed at a predetermined first position enabling the TCP to be detected, the first head being disposed at a second position enabling the first TCP to be pressed, the second position being different from the first position.

2. The system of claim 1 , wherein the rotatable stage includes a peripheral edge, the plurality of heads being disposed in an arc at the peripheral edge of the rotatable stage.

3. The system of claim 1 , wherein a second head adjacent to the first head retains a second TCP, the first TCP being pressed and the second TCP being detected simultaneously.

4. The system of claim 1 , wherein the number of heads is five.

5. A system for manufacturing a liquid crystal (LC) display comprising:

a pressing assembly configured to press a tape carrier package (TCP);

a plurality of supplying units, each supplying unit being configured to supply TCPs; and

a plurality of transferring units, each transferring unit being configured to transfer a supplied TCP from a supplying unit to the pressing assembly.

6. The system of claim 5 , wherein the pressing assembly comprises:

a rotatable stage; and

a plurality of heads disposed on the rotatable stage, each head being separated from each of its neighboring heads by a predetermined distance, the heads being enabled to rotate together with the rotatable stage in order to transport a tape carrier package (TCP), a first head retaining the TCP and being disposed at a predetermined first position enabling the TCP to be detected, the first head being disposed at a second position enabling the first TCP to be pressed, the second position being different from the first position.

7. The system of claim 6 , wherein the pressing assembly further comprises:

an aligning unit configured to align the TCP supplied to the predetermined head;

a detection unit configured to detect the TCP aligned by the aligning unit; and

a pressing unit configured to press the aligned and detected TCP together with an LC display panel assembly.

8. The system of claim 7 , wherein the first position is disposed before the detection unit.

9. The system of claim 7 , wherein the second position is disposed before the pressing unit.

10. The system of claim 7 , wherein the rotatable stage includes a peripheral edge, the plurality of heads being disposed in an arc at the peripheral edge of the rotatable stage.

11. The system of claim 7 , wherein a second head adjacent to the first head retains a second TCP, the first TCP being pressed and the second TCP being detected simultaneously.

12. The system of claim 6 , wherein the number of heads is five.

13. The system of claim 6 , wherein each of the transferring units comprises:

a supporting member for holding the TCP; and

a moving unit for moving the supporting member.

14. The system of claim 13 , wherein the moving unit further comprises:

a vertical moving member; and

a horizontal moving member.

15. The system of claim 6 ,

wherein the number of supplying units is two, the two supplying units being a first supplying unit and a second supplying unit, and

wherein the number of transferring units is two, the two transferring units being a first transferring unit and a second transferring unit, the first transferring unit being adapted to transfer a first TCP from the first supplying unit to the pressing assembly while the second supplying unit provides a second TCP to the second transferring unit.

16. The system of claim 7 , wherein the pressing unit comprises:

a fixed stage for supporting the TCP; and

a moving stage for moving the LC display panel assembly to the fixed stage.
