It seems like every electronic device that is manufactured these days, comes with a touch screen on it. This is also true for laptop computers. Touch screen laptop computers are becoming all the rage. If you are interested in purchasing a touch screen laptop computer, you really should understand a couple of vital facts about touch screens before you make your purchase. You probably didn’t realize that there are two types of touch screens technologies that can be used on touch screen computers. The first touch screen is called a passive touch screen and the second is called a resistive touch screen.
A resistive touch screen is basically a pressure sensitive type of touch screen. Resistive touch screens are manufactured from two very thin conductive layers that carry a very small electrical charge. These two thin layers are separated by a very tiny gap of air. When the pressure is applied to a resistive touch screen with either a stylus or your finger, the screen flexes and the two conductive layers make contact with each other. Where the contact was made an electrical circuit is completed and the point at which the circuit was completed is recorded by the computer as the point at which the screen was touched.
Capacitive touch screens only recognize touch from a human finger and as a result are not quite as accurate as a resistive touch screen which is capable of recognizing the fine points from a stylus. These touch screens are made up of an insulator materials such as glass that is coated with some sort of transparent conductive coating. This coating is charged with a very small electrical current and when you touch the screen, your finger causes a small change in the capacitance of electrical current. The computer recognizes this tiny change in capacitance as the point that you touched the screen.
If you want a touch screen laptop that supports multi touch, you’re generally best off purchasing a capacitive touch screen. There have been some recent advancements in resistive touch screens that make it possible for some resistive touch screens to work properly with multi touch applications. Be sure and check the documentation thoroughly if a touch screen laptop that you are interested in purchasing is a resistive touch screen and multi touch functionality is important to you.
Many people appreciate handwriting recognition software. If you’re not familiar with handwriting recognition software let me explain it to you, this software basically makes it possible for you to write on your computer screen with a stylus and the computer will recognize your handwriting and convert it into text. If you think that you will be using your touch screen laptop in this capacity, you really should purchase a touch screen laptop that has a capacitive touch screen and an electronic stylus for the best accuracy.
