Hey Alfonso!

First of all let us start with capacitive touch screen. This kind of screen is made of coated material with glass pane. The material with which this glass is coated, can store electrical charge in it. So electrical charge stores in these types of screens.

As we all know that we humans have also electric charge in our body. So when our finger touches the screen, the charges on the screen transfer in our finger. There are some oscillators circuits in the screen which will sense that there become some decrease in the charge and where you touch, these circuit will spot this location exactly and will transfer the information to proceed your command.

IPhone is one of the best example of this screen.

Now let us talk about Resistive touch screen. The same is the case with these types of screen. These are made of glass panel but are coated with three different layers. The two layers using spacers are kept apart and the whole setup is covered by the whole setup. First layer is conductive, second as Resistive and third is Scratch resistant layer.

Nokia N97 is the best example of these types of screens.

Thanks Tunacao_Caaron1 and Kenshe.

Now I know what's the difference between the two.

Thank you very much for your answers.
