What are the touch screen monitors?

touch screen monitors are no longer limited to video games as news. Today, they can be found in many stores as part of money registers, in control panels and on many portable computers. With the growing popularity of the touch screen allowed palm pilots and other PDAs have many people even one in their pocket at all times.

The benefits of such technology are obvious. Rather than throwing along other input devices such as a mouse or keyboard, the user only needs a finger to handle the selected device. However, not only mobile devices benefit from this type of input. All types of devices can be equipped, including TV and computer monitors, LCD screens and older CRT computer monitors. As a result, the bartender can press on the screen to ring drinks at a busy night before writing the price, the nurse can enter the patient's information with one hand. Indeed, the options with the touch screen monitors are endless.

Touch screen monitorsY usual in three varieties that allow him to recognize a person's touch. It is a resistance, capacity and surface acoustic wave. The resistance type works so that it has two panels with thin space. When the user presses the screen, both panels touch at this point and the exact coordinates are then registered at the computer.

The

capacitive system starts a small electric charge throughout the touch screen. When the user touches the selected area, part of the electric charge is distributed to the finger and reduces the charge at this point. The coordinates are re -recorded and sent to your computer. This type of touch screen creates a brighter image because it transmits more light and does not require two panels.

Finally, the surface acoustic wave system is the best and results in the brightest picture. Converters are used to send electrical signals via Screen, and if the user touchedE screens can determine where it is based on how the electrical signal is accepted from one converter to another.

Since the capacity system must have a finger to absorb electricity, most inanimate objects will not register as a touch. On the other hand, resistance and surface acoustic wave systems respond to almost any form of pressure. As a result, each has different advantages and manufacturers will only find new ways to use them.
