Resistance touch screen and capacitance touch screen which good？

One：working principle of

    1.Resistive touch screen：The resistive touch screen consists of a top glass layer with a conductive coating and a polyester top sheet with a conductive coating on the bottom.The conductive surface is separated by an "insulating point," usually a bead of glass printed on a coated glass.

    2.Capacitive touch screen：Capacitive touch screen is a four-layer glass screen surface，Laminated on a glass screen with ITO, the outer layer is a thin layer of quartz glass，The laminated ITO coating is a face, the four electrode leads are four corners, and the good shielding of the ITO inside ensures a good working environment.

Two:Touch sensitivity

    1.Resistive touch screen：Pressure is required to make contact with each layer of the screen，You can use a variety of touch media such as a pen, finger, and gloved hand.

    2.Capacitive touch screen：The slightest contact from an electrified finger can also activate the capacitor sensors below the screen.

Three：Accuracy

    1.Resistive touch screen：Accuracy reaches a single display pixel，Facilitates handwriting recognition，Helps operate under an interface that uses small control elements.

    2.Capacitive touch screen：Theory can reach several pixels，The actual contact area will be affected by restrictions。It is difficult to accurately click on a target of less than 1 cm.

Four：Multi-touch feasibility

    1.Resistive touch screen：Multi-touch is not supported

    2.Capacitive touch screen：Depending on implementation and software

Five：Damage resistance

    1.Resistive touch screen：The fundamental characteristics of the resistive screen determine that his top is soft，In this way the screen is very easy to scratch，Resistive screens require a protective film and relatively frequent calibration.

    2.Capacitive touch screen：ITO glass can be used for the outer layer.

Six：Clean

    1.Resistive touch screen：Use a stylus or nail to operate，It is not easy to leave fingerprints on the screen, oil stains.

    2.Capacitive touch screen：The entire finger touch, the outer layer of glass is easier to clean.
