Touchscreens 101: Resistive vs Capacitive
[HTC Hero has a capacitive // palm Treo Pro has a resistive] Hello readers it’s me once again and since there has been an on going trend of touch screen devices I have taken it as my geeky duty to explain the differences between the 2 dominant kinds. Resistive – These work on resistance (i.e. pressure) when you use a stylus or your finger two thin films on the screen connect and finish a circuit this charge is then interpreted as an input. Capacitve – These work on capacitance (i.e. charge) each person has a small charge and with this technology the screen has a field which when interrupted registers as an input. Here are examples of devices with resistive screens: Most Windows Mobile Professional devices (to date only the HTC Touch HD2 has WM & capacitive screen) On the capacitive side: We have the iPhone and Android devices The plus side for resistive is that you can use them even with gloves on as they are based on pressure on the screen. You cannot do this wi...
