A touchscreen is a visual display that acts as an input device, by responding to the touch of a user's fingers, hand, or an input device such as a stylus. The touch screen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or any other intermediate device (other than a stylus, which is optional for most modern touch screens). There are a variety of touch screen technologies with different methods of sensing touch. In LUPHITOUCH we mainly provide the resistive touch screen panels and capacitive touch screen panels. > What is Resistive Touch Screen Panels?A resistive touch screen panel comprises several layers, the most important of which are two thin, transparent electrically-resistive layers separated by a thin space. These layers face each other with a thin gap between. The top screen (the screen that is touched) has a coating on the underside surface of the screen. Just beneath it is a similar resistive layer on top of its substrate. One layer has conductive connections along its sides, the other along top and bottom. A voltage is applied to one layer, and sensed by the other. When an object, such as a fingertip or stylus tip, presses down onto the outer surface, the two layers touch to become connected at that point: The panel then behaves as a pair of voltage dividers, one axis at a time. By rapidly switching between each layer, the position of a pressure on the screen can be read. Resistive touch is used in restaurants, factories and hospitals due to its high resistance to liquids and contaminants. A major benefit of resistive touch technology is its low cost. Additionally, as only sufficient pressure is necessary for the touch to be sensed, they may be used with gloves on, or by using anything rigid as a finger/stylus substitute. Disadvantages include the need to press down, and a risk of damage by sharp objects. Resistive touch screens also suffer from poorer contrast, due to having additional reflections from the extra layers of material (separated by an air gap) placed over the screen. > What kind of resistive touchscreen we can supply?     1) 4 wires resistive touchscreen;      2) 5 wires resistive touchscreen;     3) 8 wires resistive touchscreen;     4) Digital resistive touchpanels;   > What is Capacitive Touch Screens?A capacitive touch screen panel consists of an insulator such as glass, coated with a transparent conductor such as indium tin oxide (ITO). As the human body is also an electrical conductor, touching the surface of the screen results in a distortion of the screen's electrostatic field, measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location is then sent to the controller for processing. Capacitive touchscreens are those that respond to the electrical properties of the human body. This means that they can be controlled by a light touch, and don't require the user to exert heavy pressure on the screen. The drawback to a capacitive touchscreen, though, is that it usually cannot be controlled by a gloved finger or an input device, such as a stylus. There are some input devices that have been optimized for use with capacitive touchscreens, though.Capacitive touchscreens also are the only ones capable of multi-touch, which allows the display to recognize more than one point of contact. Without multi-touch, you cannot use gestures such as pinching and spreading a screen to zoom in and out.> What kind of capacitive touchpanels we can supply?  1) Capacitive touchscreen panels;  2) ITF for Interactive Electronic White Board;  3) Capacitive touch sensors;  4) Fingerprint Recognition Touch Sensors;   5) Fingerprint Recognition Touch Keypad  > What is ITF?   LTF means Interactive Touch Foil.
