Multiple UART connection with Arduino Uno Rev3

Hi,

I got 1 Arduino Uno rev 3, 1 shield interface, 1 graphic LCD , and 2 other chips that will be used to connected through UART.

Can I know whether the graphic LCD shield can support multi connection through UART to the 2 chips ?
It seems like possible cause the LCD shield has 3 lines of Rx and TX ( + - and D) ?
