FAQ
Q
How do I know if my touch is resistive or capacitive
A
If you pay attention, you'll notice the difference between the two screens. In the case of capacitive touchscreens, such as on very expensive smartphones and tablets, are very responsive to the slightest touch. Meanwhile, resistive touchscreens may require more pressure, or the use of a stylus.

Q
The inventor of touch screen
A
Historians consider the first touch screen to be a capacitive touch screen invented by E.A. Johnson at the Royal Radar Establishment, Malvern, UK, around 1965 - 1967. The inventor published a full description of touch screen technology for air traffic control in an article published in 1968.

Q
Capacitive touch screen VS resistive touch screen
A
The technology behind resistive touchscreens
Resistive touchscreens rely on the pressure of your fingertip – or any other object – to register an input. These touchscreens consist of two flexible layers with a gap of air gap in-between. In order for the touchscreen to register an input, you must press on the top layer using a small amount of pressure to depress it enough to make contact with the bottom layer. The touchscreen will then register the precise location of the touch.
The technology behind capacitive touchscreens
Rather than relying on pressure, capacitive touchscreens instead sense conductivity to register input – usually from the skin on your fingertip. Because you don’t need to apply pressure, capacitive touchscreens are more responsive than resistive touchscreens. However because they work by sensing conductivity, you can only use capacitive with objects that have conductive properties, which ideally includes your fingertip or a special stylus designed with a conductive tip.

Q
What is capacitive touch screen
A
A capacitive touch screen is a control display that uses the conductive touch of a human finger or a specialized device for input.
Unlike resistive and surface wave panels, which can sense input from either fingers or simple styluses, capacitive touch screen panels must be touched with a finger or a special capacitive pen or glove. 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.
When a capacitive panel is touched, a small amount of charge is drawn to the point of contact, which becomes a functional capacitor. The change in the electrostatic field is measured to find the location. In some designs, circuits located at each corner of the panel measure the charge and send the information to the controller for processing. In multi-touchscreens, sensors are arranged in a grid to enable more complex input.
Input to resistive touch screens works through pressure resulting in two conductive layer

Q
What is Multi-Touch technology?
A
Multi-Touch technology works with TrackPads (or TouchPads) and touch-screen interfaces, like those found on laptops, smartphones and tablets. It allows users to interact with their devices in a multitude of ways, by expanding the number of interface options. Rather than simply swipe and tap, Multi-Touch allows for zooming, scrolling, selecting, and more. It is designed to provide touch-screen interfaces with the same sort of flexibility and usability that a traditional mouse and keyboard provide, while also providing for a more intuitive and seamless user experience.
Our capacitive touch screen can support 5/10 touch points.

Q
How does Multi-Touch work?
A
Multi-Touch technology works with touch-screen and TrackPad interfaces. Both of these surfaces are able to measure and respond to pressure through the use of a pressure-sensitive panel carrying an electrical charge. Where a pressure is applied, the electrical charge is disrupted, which is read by the computer as an input. This input is then translated to a corresponding motion or function by the device's software. Multi-Touch technology allows these panels to read and interpret multiple pressure points, including gestures, at the same time.

Q
What is Touch Screen Controllers
A
Touch screen controllers are circuits that interface between a touch screen sensor and the device the sensor is used to control. They plug into touch screen sensors and interface with computers via serial connections such as RS232 and the universal serial bus (USB). Touch screen sensors have a transparent surface that is surrounded by a sensor array that provides position information to a processor. They enable operators to use a touch screen display as the input device, thus replacing the keyboard or mouse as the primary method of interacting with the device. Examples of touch screen technology include automatic teller machines (ATMs) and point-of-sale (POS) kiosks. Both types of products may use multi-point sensing or universal touch screen controllers. Touch screen controllers are used with several one or more types of touch screen sensors. Examples include capacitive touch screen sensors and resistive touch screen sensors. Complete touch screen systems are also available.

Q
What is the Touch Screen Koisk?
A
A Touch Screen Koisk is an input device normally layered on the top of an electronic visual touch display of an information processing system. A user can provide input or control the information processing system through very simple or mult-touch gestures by touching the screen with a special stylist or one or more fingers. The touch screen kiosk facilitated the user to interact without deviation with what is displayed, rather than using a mouse, touch pad, or any other intermediate device.

Q
What is the touch screen overlay?
A
An intouch Interactive Touch Screen Overlay transforms any LCD or LED display / TV into an interactive touch screen.
The toughened glass overlay is manufactured with a permanent or removable fix for installation directly to the screen bezel / frame. Simply retrofit an Interactive Touch Glass Overlay to convert existing screens into multi-touch, interactive displays.

Q
How to calibrate the touch screen?
A
Only units with resistive touchscreens need to be calibrated. PCAP do not require calibration.
