18.5 Inch Multi-Pont Capacitive Touchsreen PCAP Touch screen for Touch Monitor PC
A capacitive touch screen is a control display that uses the conductive touch of a human finger or a specialized device for input. The panel is coated with a material that can store electrical charges and the location of touch to the screen is signaled by the change in capacitance in that location.
Which is better resistive or capacitive touch screen ?
If you want increased screen contrast and clarity, capacitive touch screens are the preferred option over resistive screens, which have more reflections due to their number of layers. Capacitive screens are also far more sensitive and can work with multi-point inputs, known as 'multi-touch'.
How dose a capacitive touch screen work ?
Capacitive screens do not use the pressure of your finger to create a change in the flow of electricity.In both instances, when a finger hits the screen a tiny electrical charge is transferred to the finger to complete the circuit, creating a voltage drop on that point of the screen.
