Projected Capacitive Touchscreens

Projected Capacitive (PCap) touchscreens are used on the vast majority of smartphones and tablets. PCap screens consist of a layer of glass, a matrix of electrodes and a protective film. The matrix of electrodes creates a three dimensional electrostatic field that registers even the slightest change in electrical current. So, when a conductive object, such as your finger or a stylus, comes into contact with the matrix of electrodes, the electric field is changed slightly, and the screen registers your touch

Capacitive Touchscreen Advantages

A capacitive touchscreen:

• Facilitates more accurate input. Because there is little or no leeway for the capacitive touchscreen system to interpret input inaccurately, the potential for errors—whether in transaction or in customer order detail—is minimized
• Touts a higher degree of contrast. A capacitive touchscreen can be seen more easily.
• Offers easy, flexible operation. A capacitive touchscreen comprises two layers of glass, coated with a conductor agent, like iridium tin oxide. The conductor agent reacts to the touch of a human finger or special-tipped stylus on the screen. This causes a change in the local electrostatic field and indicates to the system exactly which area, number, or icon on the screen has been touched. A capacitive touchscreen also supports multi-touch—e.g., simultaneous pressing on an icon and enlargement of an image on the screen.
• Features enhanced durability. A capacitive touchscreen can, in certain ways, be more durable than its resistive counterpart. Why? Frequently used areas on a capacitive touchscreen do not typically start to break down and become unresponsive over time and with heavy use. Additionally, a capacitive touchscreen that is scratched, pierced, or cracked will continue to operate. This can occur if employees try to operate the device with something other than their finger or stylus, if they tap the glass too hard, or if a mobile device is dropped. This is not true of a resistive touchscreen, which in most cases stops working whenever the surface is damaged.

Because a capacitive touchscreen keeps working even if it suffers damage, there’s no need to interrupt store or restaurant operations in order to install a replacement. This minimizes customer frustration and lost sales.

Capacitance Touch screen Construction

Several techniques are available to construct a capacitance touchscreen. These include conductive wire construction or the application of transparent conductive materials, such as Indium Tin Oxide (ITO), to a polyester (PET) film layer "sandwich" or to a glass substrate.Capacitive Touch Panel TechnologyCapacitive touch panel is a four-storey glass screen surface and laminated within the glass screen is coated with a layer of ITO, the outermost layer is a thin layer of silica glass, laminated ITO coating as a face, four electrode leads in the four corners, inner ITO good shielding to ensure a good working environment.
When finger touch the metal layer that is, because the body farm, users and touch-screen surface with a coupling capacitor, high frequency current, capacitance is a direct conductor, so fingers sucked away a very small amount of current from the contact point. The respectively current outflow from the touch electrode on the four corners of the screen, and flows through the four electrode current is proportional to the distance from the fingers to the four corners, controller through the accurate calculation of the four current percentage, came to the location of the touch point.
