A touch screen or multi touch screen is an assembly of an input device and an output device. Typically, the touch screen is generally layered upon an integrated image processing unit (IGU) of an information handling system. While the unit may be a computer, the screen is most commonly LCD or LED touch screen. This multi touch screen allows for a user to interact with the input device such as a stylus, finger or other objects while performing simple tasks.

As mentioned above, a touch screen uses two transducers that are arranged in a linear manner along the long axis of the touch panel. These conductors are sensitive to the stimulus applied to them. The electrical signals created by these transducers are converted by the ito into pixel information that is then sent to the monitor. In some models, this process is completed digitally rather than mechanically. The result is that the output from the model is digitized and then displayed on the monitor. The unit is then covered with a shield to prevent signal distortion due to interaction with other transducers and active components within the device.

On the inside surface of the touch screen are millions of tiny electrodes that are heated using a small electrical charge. When the finger makes contact with either side of the device, a tensile force is produced causing the electrodes to contract and release a bit of electric current in response. Since the charge changes only in one dimension, this can be implemented as a resistive or Capacitive touch screen where the finger’s position determines the amount of electric current generated. This technology allows for a wide range of capacitance and resistance levels as well as multipurpose functionality that can be customized for a specific application.

In most modern devices, a finger sensor is built into the device as well as a location-specific application processor. This allows the user to simply place their finger on the screen and immediately recognize a certain touch or location on the screen. For instance, if a person is typing on their computer keyboard, they could use this technology to not only recognize that finger but also to enter any specific key on the keyboard. If they wish to scroll down a web page with their mouse, a touch screen is much more convenient because they can simply slide their finger along the surface instead of using their entire hand. This is a lot easier than having to continually re-clicking your mouse to move the cursor up or down the page.

The main drawback to using an electronically controlled touch screen is that your fingers will eventually grow tired and lose their sensitivity to the signals. It has been proven that users who have used this technology for long enough eventually develop the habit of looking at the screen than at the computer keyboard. One possible solution to this problem is to place your hand on a cup of oxygenated water before touching the screen. This practice relaxes the fingers allowing you to better focus your attention on where you are actually typing.

With some touch screen devices, you may find that the finger pad is made out of a semi-transparent, rubbery material. This semi-transparent material provides the finger with the necessary tactile feedback without having to actually type on the touch screen. While it is a nice novelty touch screen, it does make it a little bit more difficult to type since there isn’t any actual touch. This type of stylus is most commonly found on tablet computers or laptops. It is typically squeezable and shaped like a stylus.

Some people prefer to use touch screen protectors that are built specifically to prevent damage from fingerprints or other types of moisture. Touch screen protectors are usually made out of a high impact resistant plastic material. These kinds of products are commonly found in laptop sleeves, wrist rests, and holders for tablets. The most popular materials that are used for touch screen protectors is tempered glass and rubber. Tempered glass is often times referred to as Gorilla glass, because the glass is so tough that it allows even heavy objects to be carried by the hand without causing any damage.

There are plenty of companies that make products specifically to guard against grease, dust, and fingerprints. Most of these touch screen guards have a double conductive layer which prevents electric charge from leaking through onto the touch-sensitive surface. When the electrical charge leaks through, the result is a very small amount of damage that is typically imperceptible after several seconds of the electric charge leak. After this has occurred, you can simply wipe the touch-sensitive surface with a moist cloth or baby wipes to remove the damaged area.
