7. Fold the LCD flex cable at the crease shown in Figure 16, so the name of 
the LCD panel manufacturer faces up.
The connectors on the Torisan and Sharp LCD panels are mounted in the 
reverse of each other. This means that pin 1 on the Torisan panel connector 
is at the opposite end when compared to pin 1 on the Sharp panel 
connector. Both panels have the same connector, but the connector is 
mounted differently. 
The LCD flex cable can connect to either panel by making one fold to the 
cable. The words To r i s a n and Sharp are printed on the cable (see 
Figure 16). If you are installing a Torisan LCD panel, fold the cable at the 
crease so the word To r i s a n is facing up. If you are installing a Sharp LCD 
panel, fold the cable at the crease so the word Sharp is facing up.
