Method of making organic light emitting display device
A method of making an organic light emitting display device is capable of enhancing the accuracy of a lighting test. The method of making an organic light emitting display device comprises: forming at least one first panel on top of a large substrate and forming at least one second panel on a bottom of the large substrate; forming independent pads, each receiving and transferring power supply from the exterior to the panels formed on the large substrate, the number of independent pads being the same as the number of panels; and forming independent wires between the panels and pads, the independent wires between the panels and pads each having the same length.
1. A method of making an organic light emitting display device, comprising the steps of:
forming at least one first panel in a first region on a substrate and forming at least one second panel in a second region on the substrate, with the first and second regions being contiguous;
forming independent pads, each independant pad receiving and transferring electrical power supplied from an exterior source onto the first and second panels formed on the substrate, the independent pads being equal in number to the panels; and
forming independent wires between the panels and the independent pads;
corresponding ones of the independent wires between the panels and the independent pads having a same length for each panel; and
said independent pads connected to the first panel being formed on a side of the first panel with the side of the first panel being fartherest from the second panel, and said independent pads connected to the second panel being formed on a side of the second panel with the side of the second panel being fartherest from the first panel.
2. The method according to claim 1 , wherein each of the independent pads independently transfers a same power supply and same driving signals to each of the panels.
3. The method according to claim 2 , wherein images displayed on said at least one first panel formed on the top of the large substrate and images displayed on said at least one second panel formed at the bottom of the large substrate are symmetrical with each other in an upward and downward direction.
4. The method according to claim 1 , further comprising the step of performing a lighting test on the panels using the pads.
5. The method according to claim 4 , further comprising the step of cutting the large substrate, allowing each of the panels to be used independently.
6. A method of making an organic light emitting display device, comprising the steps of:
forming first and second panels in a first region on top of a substrate, and forming third and fourth panels in a second region on top of the substrate, with the first and second regions being contiguous;
forming a first pad corresponding to the first panel and first wires connecting the first panel to the first pad;
forming a second pad corresponding to the second panel and second wires connecting the second panel to the second pad;
forming a third pad corresponding to the third panel and third wires connecting the third panel to the third pad; and
forming a fourth pad corresponding to the fourth panel and fourth wires connecting the fourth panel to the fourth pad;
the first wires, the second wires, the third wires and the fourth wires having a same length; and
said first and second pads being formed in the first region on a side of the first and second panels, respectively, fartherest from the second region, and said third and fourth pads being formed in the second region on a side of the third and fourth panels, respectively, fartherest from the first region.
7. The method according to claim 6 , wherein the first, second, third and fourth pads receive a same power supply and same driving signals so as to transfer them to the first, second, third and fourth panels, respectively.
8. The method according to claim 7 , wherein images displayed on the first and second panels and images displayed on the third and fourth panels are symmetrical with each other in upward and downward directions.
9. The method according to claim 6 , further comprising the step of performing a lighting test on the panels using the pads.
10. The method according to claim 9 , further comprising the step of cutting the large substrate, allowing each of the panels to be used independently.
