Touch screen technology is now ubiquitous, yet remains an innovative marvel. This article explores the various types of touch screen technology, their respective strengths and weaknesses, common applications across industries, and important maintenance considerations.
Touch screen technology is so widely available and its application so accessible – in the form of digital camera screens, ATM machines with touch panels, mobile phone screens, PDAs, and even laptop monitors – that it is almost taken for granted nowadays. Yet it is truly an amazing innovation that would have been the stuff of science fiction merely 40 years ago. If you want to know more about this remarkable innovation, read on:
Types of touch screen technology
There are many different types of touch screen technology, including capacitive touch, infrared, optical imaging, resistive, and surface acoustic wave. These technologies differ in the mechanisms they use and the processes by which they enable touch screen functionality. For example, a capacitive touch panel works with an electric field; surface acoustic wave uses ultrasonic waves; infrared uses light beams; and acoustic pulse recognition uses mechanical vibrations created by the touch of a finger.
Strengths and weaknesses of these technologies
Perhaps the most commercially available touchscreen technology to date is projected capacitive touch technology, used by such gadgets as the iPhone and iPod Touch, Palm Series, Sony Walkman series, and many others. This is due to the technology’s comparatively high durability and clarity. Its weakness, however, is its limited sensitivity capabilities; it only responds to direct finger contact.
Optical imaging is one of the most recent developments in touch LCD technology; it is able to measure the size of the touch location, and this technology is comparatively affordable, versatile, and resilient.
Many public touch monitors use force panel technology (wherein gauges determine the location of a deflection on the touch monitor caused by touch) because of their very high durability and resistance to environmental elements.
Dispersive signal technology touch display technology is able to withstand environmental elements such as dust and dirt, while at the same time being highly sensitive and responsive to elements that can concentrate touch at a single point (such as fingers, stylus, etc.).
Applications of touch screen technology
There are so many applications of this technology, not just for the phones, game consoles, and iPods that you are exposed to on a daily basis. Industries that use touch screen technology include transportation, machine control systems, medicine, engineering, and the list goes on. Touch screen products include touch computers that enable you to manipulate software programs simply by touching the screen; these can be found in restaurants, malls, public kiosks, and services for the handicapped.
Other issues
There may be other issues related to touch screen technology, such as their relatively low durability (about 3 to 5 years) and their need for careful handling. Also, touchscreens that require the use of fingers may be harder to manipulate, especially for individuals with broad fingers. Some touch screen systems are more sensitive to scratches, so it is very important that electronics using touch monitors and touch displays are covered in protective casing whenever not in use.
There you have it! This is just some of the information that you may find useful as a starting point for learning about touchscreen technology. Continue to enjoy your iPod Touch and be glad you were born in this time of modernization!
