Touch screen monitor is the type of display panel that does not utilize a pointing device such as mouse for navigation or selecting. Instead you can use you finger or even a stylus pen to point directly to the objects that show up on the screen. Touch screen monitor has a touch-sensitive transparent panel that covers the screen in order for it to work directly on the screen.
The advantages of utilizing such technology in computing are pretty obvious. As said, rather than depending on a mouse or keyboard, the user can now easily manipulate thing on the screen by just directly pointing on it.
This is particular true for business applications as these monitors can be used as point-of-sale machines in a variety of settings or they might be installed in kiosks that provide user for information or ticketing services. A business or sales executive can find this monitor pretty useful too especially when doing business presentation. It also drives up productivity and creativity.
The touch screen technology can also be found in electronic gadgets and devices such as mobile phone, personal organizer and GPS unit system; not just on a computer screen. Touch screen monitor has made everything better and easier compares to when such thing does not exist. The possibilities with touch screen monitor are endless.
Different Types of Touch Screen Monitor
There are three different varieties of touch screen monitor panel, well at least in the technical aspect: resistive, capacitive and surface acoustic wave. Below are the descriptions of there touch screen monitors:
- Resistive - this technology works by having two separate panels put together with a thin space between them. When the screen is pressed, the pressure that falls on the certain spot will make the two panels come in contact and thus, the exact coordinates are then registered for further action by the computer unit.
- Capacitive - this system works by employing a small electrical charge throughout the touch screen. When a user touches a spot on the screen, some of the electrical charge will then be distributed to the finger and lessening the charge at that exact point. The coordinate will be recorded and sent to the processing unit for further action. This type of touch screen is better than the one mentioned before; it produces a clearer picture as it transmits more light and doesn't require two panel for functioning.
- Surface acoustic wave - this is the best technology in touch screen among all. It produces the best and clearest picture and most latest lcd touch screen monitor and computers that you find in the market today are based on this technology. Unlike the previous models, this one utilizes transducer for sending electrical signals across the screen and if a user touches the screen, the system can determine where is the location based on how the electrical signal is received from one transducer to the other.
Pro and Con of Touch Screen Monitor Application
Touch screen monitor is one of the best inventions in the computing world; the application of such technology has made technology devices and gadgets to perform better and user-friendly. No longer that you need to press on the small key pads on your mobile or PDA as you can now do it directly on the screen which is much easier and convenient. In case if that's hard to do, a stylus pen can be used instead for better navigation and control.
Although touch screen monitor provides a natural interface for computer users, that does not mean that this electronic device does not have any drawback. A user that works long hour on a computer that fully utilizes the touch screen technology will soon find out that his or her arm become very tired. Moreover, without a keyboard, the user will not be able to work efficiently and fast. It is definitely awful to type on the screen; it's slower and inconvenient and that's why we can find add-on devices such as keyboard for the iPad sold in the market. Touch screen monitor is good when it is being used for light applications such as in business presentation and as a point and sales machine, it's not ideal for full computing application.

Thanks prasetio for your comment. Yeap, touch screen monitor is great particular who those who involved in graphic designing stuffs. Things can be manipulated easier on them.
You take care too..
