I wonder why this question has been downvoted.

However, Tamer, what exactly do you mean by "LED screen"? Is it a computer monitor (or TV screen) connected through either of VGA, DVI, HDMI, DisplayPort?
Or is it a device connected through RS232, serial port, parallel port, printer port?
Is it a USB device?

You should read the documentation of the LED screen and send data on the serial line accordingly.

It depends on the LED screen.
You need to investigate its documentation. Most likely there will be some commands that you can send to the screen. And there has to be a possibility to tell the screen what text it should display. Find out what the screen expects at its serial interface.

Try to connect via Windows' HyperTerminal or some similar program. This way you can play around a little with commands and text lengths and so on.

When you know what you want to send, the serial port class[^] is what you need to do it programatically.
   
Read this[^] article.
   
Thank you all;
But this is not my question, in other wise :
there is a mobile LED screen connected by serial port to my PC : in my windows form there are some results on the textbox must be only displayed on that led screen.
so my question is how to display on the led screen on the value of the textbox ???
