Projection-capacitive touch glass

Projection-capacitive touch glass is used in many areas. This device is characterized by high performance and versatility. A special technology is used to manufacture the products, which allows to increase the sensitivity of the screen. As a result, it responds to the touch of many users, easily recognizes various actions, as well as provides the ability to control with gestures. The principle of operation resembles the work of infrared panels, but has a number of significant differences. They reflect the advantages of the device compared to similar products.

Capacitive technology is that the oscillations of electromagnetic waves are used to fix the user’s touch. It is the change in voltage in the elements of the touchscreen that allows you to obtain data on the coordinates of the user’s finger or stylus. The technology has some advantages. It significantly reduces the time spent on recording data with LEDs. Data is read much faster, which reduces the likelihood of incorrect response to certain actions, as well as to record the touch of several users at the same time with minimal error.

Characteristics of projection-capacitive sensor glass

Projection-capacitive technology is a novelty in the field of information technology. It is the latest generation sensor that meets all standards and also allows you to perform a wide range of actions. This component is actively used to create tablets and smartphones. This solution is characterized by high speed of data capture and processing. The technology works as follows. The sensors are fixed between the glass layer and the LCD panel of the screen. When the finger touches the display, the coordinate values ​​read by the user are read. This allows you to transfer data faster with minimal risk and loss.

You do not need to use a monitor frame for this technology. That is why this device can be used on different types of surfaces, which allows you to transmit brightness in a wide range, compared to analogues.

Unlike conventional infrared interactive panels, such solutions are much more expensive. There may be problems with scaling. There are solutions for not all types of displays. For large screens you have to make an individual order.

It is better to use projection-capacitive coating for commercial purposes, as well as for presentations and training. It is more stable and durable. Provides clear display even with high distribution quality of the original screen.

The specifics of technology can solve a number of important issues. This solution makes it possible to simplify the interaction with interactive elements. You no longer have to work hard to get results. It is easy enough to touch the desired area. Pressing also processes information faster than infrared interactive sensors.

It is possible to work in gloves. Any antistatic gloves are suitable for interaction with the surface. The screen has enough sensitivity to perceive a stylus or marker. This is the best option for educational institutions. This device will replace the usual board.

Benefits

Touch screens, which work in accordance with the projection-capacitive technology, consist of a grid of electors, which is applied to the inside of the monitor. When the user touches the display, the applied electrode creates a capacitor. To calculate the point of contact, the capacitance of the capacitor in the area of contact is measured. After processing the information, the corresponding coordinates are obtained, which are used to perform the task. Among the advantages of this technique are the following:

• The sensors are behind a protective surface. This allows you to ensure stable operation in adverse weather conditions. For example, in the event of rain or snow, the outer coating protects the internal structure of the electrodes, which are responsible for capturing and transmitting signals. The surface is also resistant to the negative effects of dirt or dust. If there are any temperature differences, condensate does not interfere with the work of the interactive table or panel.
• The touch screen is easy to install and use. No need to use additional devices. It is enough to connect the equipment to the network. You can then use it. As a rule, you already have all the installed software needed to do the job.
• The upper glass is usually resistant to shocks and other adverse effects. This keeps the device working regardless of the conditions. At small damages of glass work with installation is possible. This is due to the special structure of the screen.
• The display will work by touching a metal or other solid object, allowing it to be used in a variety of conditions.

These advantages are inherent in most models of interactive glass that operates on projection-capacitive technology. This makes it possible to choose the optimal device that will meet all the needs of the user depending on the field of use.

Hardware Application

Touch screens are used in various fields. They are usually used in administrative and public institutions, where it is important to provide users with the necessary information. Among the possible uses are the following:

• Payment terminals, kiosks and information machines, various ticket machines and terminals located on the street. These devices allow users to get the service they need or pay for a service.
• Information booths set up next to stores in malls. There are different models and versions, which allows you to choose the most functional model.
