capacitive touch screen monitors quotation

This monitor supports multi-point projective capacitive touch screens, The double glass design of the capacitive touch screen can not only protect the conductors and sensors but also prevent external environmental factors from affecting the touch screen. Even if the screen is dirty, dust, or oil stains, the capacitive touch screen can still accurately calculate the touch position.

The interface of the industrial monitor determines the quality of image transmission. At present, common interfaces of Touch Think industrial monitor include HDMI, DP, DVI, VGA, and RJ45, and so on. And we support more customized interfaces.

The industrial monitors have passed the EMI/EMC test, are suitably used in multi-environments, and have the capability for electromagnetic interference in the environment has a certain degree of immunity, namely high electromagnetic sensitivity.

Touch-screen monitors have become more and more commonplace as their price has steadily dropped over the past decade. There are three basic systems that are used to recognize a person"s touch:

The resistive system consists of a normal glass panel that is covered with a conductive and a resistive metallic layer. These two layers are held apart by spacers, and a scratch-resistant layer is placed on top of the whole setup. An electrical current runs through the two layers while the monitor is operational. When a user touches the screen, the two layers make contact in that exact spot. The change in the electrical field is noted and the coordinates of the point of contact are calculated by the computer. Once the coordinates are known, a special driver translates the touch into something that the operating system can understand, much as a computer mouse driver translates a mouse"s movements into a click or a drag.

In the capacitive system, a layer that stores electrical charge is placed on the glass panel of the monitor. When a user touches the monitor with his or her finger, some of the charge is transferred to the user, so the charge on the capacitive layer decreases. This decrease is measured in circuits located at each corner of the monitor. The computer calculates, from the relative differences in charge at each corner, exactly where the touch event took place and then relays that information to the touch-screen driver software. One advantage that the capacitive system has over the resistive system is that it transmits almost 90 percent of the light from the monitor, whereas the resistive system only transmits about 75 percent. This gives the capacitive system a much clearer picture than the resistive system.

On the monitor of a surface acoustic wave system, two transducers (one receiving and one sending) are placed along the x and y axes of the monitor"s glass plate. Also placed on the glass are reflectors -- they reflect an electrical signal sent from one transducer to the other. The receiving transducer is able to tell if the wave has been disturbed by a touch event at any instant, and can locate it accordingly. The wave setup has no metallic layers on the screen, allowing for 100-percent light throughput and perfect image clarity. This makes the surface acoustic wave system best for displaying detailed graphics (both other systems have significant degradation in clarity).

Another area in which the systems differ is in which stimuli will register as a touch event. A resistive system registers a touch as long as the two layers make contact, which means that it doesn"t matter if you touch it with your finger or a rubber ball. A capacitive system, on the other hand, must have a conductive input, usually your finger, in order to register a touch. The surface acoustic wave system works much like the resistive system, allowing a touch with almost any object -- except hard and small objects like a pen tip.

Toponetech`s 19 inch gaming open frame touch display with External Acrylic LED Bar (Front) is available in both standard and custom touch display for slot machine sizes, Toponetech’s projected capacitive touch screens are form, fit or function replacements for 3M™ and Elo™ touch sensors.

A touchscreen monitor incorporates the function of the pointing device into the display, replacing both mouse and keyboard. Interaction with the computer takes place via a system which detects contact with the screen surface.

Resistive screens are differentiated by the number of wires they have. The five-wire system compensates for their fragility, making them more durable and less prone to scratches and cracks.

Capacitive models respond to the transfer of electrical charges when touched, and cannot be used while wearing a glove. They are very bright, but have a fragile surface coating. Projected capacitive versions take advantage of the proximity transfer effect. Their surface is protected by reinforced glass.

Infrared technology uses light detection, the screen responding even before it is touched. However, it offers limited resolution and is prone to accidental activation. The most common type is the surface acoustic wave (SAW) screen. It responds to a wide variety of touch techniques, some screens even taking into account the amount of pressure applied. It is very bright and has excellent resolution.

In addition to size and resolution, choice of touchscreen will depend on the conditions under which it will be used and the possible need for multi-touch capability.

Maple Systems Capacitive Touch Monitors and Display"s state-of-the-design include more I/O, multiple mounting options, a rugged steel chassis, and high-resolution capacitive touchscreen size options. Each unit is fully certified to meet European CE standards, FCC, & RoHS certifications.

A touch-screen display is a type of screen that allows the user to interact with the operating system using their fingers, without having to use physical buttons. In industrial environments, a touch screen monitor is essential for direct operator interaction with systems and machines.

Resistive touch monitors are the simplest and most economical technology, made from two layers of plastic covered with a conductive material and separated by an additional insulating layer. By exerting pressure, electrical contact is generated with the layer underneath, allowing the coordinates of the contact point to be plotted.

Capacitive touch screens are more modern and innovative, with an outer glass surface crossed by a uniform electric field that varies with the contact of the user"s fingers. Importantly, thanks to this technology multi-touch is possible.

In the industrial field, the touch screens are widely used in various manufacturing sectors and in the packaging, logistics, motion control and industrial automation markets.

Compared to normal consumer touch screens, industrial touch screen monitors must have additional features based on the different industrial applications:

The wide range of latest-generation capacitive touch screens and multi-touch monitors distributed by Digimax can be fully customised according to the industrial and technical specifications required.

Rocktouch, Digimax"s partner in the distribution of industrial touch screen monitors, has also developed dedicated touch screen applications for the medical sector, such as the innovative Capacitive PCAP technology for multi-touch and the anti-bacterial treatment of industrial touch screen displays.
