What is Touch Screen? How does it work? What are the types?

Among the many products that technology has created in order to make it easier and completely user -friendly, there are touch screens that we have been using for a long time.

Many touch screen types such as touch screen laptops, watches, touch screen mobile phones, tablets and touch screen pens for these tablets have been offered to the use of people and the user has the freedom to purchase the tool they want. Undoubtedly, mobile phones are the areas where such technologies are used most frequently. Our lives "smart phone" the term the technology giant put in all of these smartphones joint technology that uses touch screen technology.

In fact, it is not possible to say that the touch screen is settled in our lives only through smart phones. Because, even though we are not aware, the areas where we have been using the touchscreen technology that has been going on for a long time have been frequently in our lives, even though we are not aware of it.

What are the Types of Touch Screen?

According to the areas where touch screen technology is used, this technology has three different panel shapes. Although the operating logic of these touch screens is to feel the touch as the main point, in some subjects, they may show different features. The mentioned differences and their features are as follows.

Probably the principal appeal of industrial touch screen technologies is your natural and direct interaction it alleviates. It's intuitive to use than a laptop or computer system, which necessitates multiple apparatus to work with and also far simpler to use.

1- Resistive Touch Screen

These types of screens are very simple touch panel systems produced with the logic of resistance principles. According to this technology, along with the length of the resistance, the decrease in resistance proceeds in the right proportion.

The increase or decrease of this resistance level varies according to the amount of current passing through the conductive part. In other words, in order for the user to give the desired operation as the core of the logic of operation, the variability in the current and the potential must exist.

Resistive touch screen models of the fingers including the screen is touched total 6 layers convenience. Touch the screen surface has a flexible structure and below the surface of the circuit layer called layer is located.

There is a conductive structure in the interior of this circuit layer. There are three other layers under the conductive structure called the lower part. There is a support glass layer at the bottom and a lower circuit layer on it. The upper parts of these layers, which also have a conductive structure, contain separator points that allow the inner structure, which is bent towards the content, to move up to a part with the effect of the pressure created when pressing the screen with fingers.

If general features of resistive touch screens are summarized; it is durable; water, etc. it can be said that it is not easily affected by external factors, it cannot perceive many touches at the same time, the energy it consumes approaches zero when it is not used, it has less permeability than other touch panels and you need to apply more pressure to work than other touch screens.

2- Infrared Touch Screen

Infrared touch screens, also known as “infrared touch screen” ; It is considered as the most durable screen among touch screens against both external scratches and external impacts. Apart from this, the most expensive screen type among touch screens is the infrared touch screens.

There is no need to apply extra power to the infrared display panels, which can easily operate with a gentle touch. This touch screen type is also divided into two different types ;

Optical Infrared Based Touch Screen: With a little touch of these types of screens, the sensors in the system are warned because you prevent the light system from passing to the other side of the panel. Located on the panel at the point where the come command processing unit determines your location and both the interior from outside the portions you touch you the coordinates you want to do is determined.

Heat-sensitive touch screen: Most used in mobile heat sensitive touch systems, when said screen is not preferred. Instead, it is more convenient to use on touch screens with button systems.

When looking at the general features of this type of screens ; Compared to other touch screens, it does not need an extra calibration, does not need any coating on them, it has a durable structure, your touch with your fingers can start the sensing process directly, it has a more limited resolution system since it has an LED system, compared to other touch screens. As it turns out, and as the name suggests, it is a heat sensitive system, and it can be said that it will not show any performance when touched with cold fingers.

3- Capacitive Touch Screen

Capacitive touch panels are different than the resistive touch screens, which are among the touch screen types we explained at first. The structure of a transparent insulating material which form the structure of the screens and capacitive touch panel which is simpler than are used in this insulator glass material through the more resistant is equipped available.

Among the features of capacitive touch screens ; According to the resistive screen more energy expenditure, strong fingers touching operation be costly to have a structure according to the resistive much more sensitivity comprises, multi-touch capacitive screen prior to their operating systems do adjusted according to resistive screen of use is not possible and the streaking problems on insulator to overcome it can be shown that it is possible to increase the durability of a layer by coating it.
