In today’s mobile market touch screens are used in phones, notebook PC and PDAs. The thing is there are various types of touch screens with their own pros & cons. One thing to keep in mind is those different types of screens acts differently and wants to be ‘touched’ differently.
Lets get a basic idea about their technology in brief:
Capacitive type: As the name implies they use the change of capacity to identify touched point on screen. These are used mainly in mobile phones and equipments such as iPhone, iPod touch etc. Usually have a good responsiveness to touch. Problem of using capacity is only some things such as human skin changes capacity of those screens when touched. In short, they are only sensitive to human skin and like elements. You cannot use thing like plastic pen (stylus) on that. And they’re also lacks precision point identification compared to others.
