LCD Touchscreen Displays – The Technology And Its Viability Look around you.. Almost every third visual display that you see out there is most definitely going to be powered by touch technology. I am not just talking about ATM vestibules and ticket vending machines. We find them in restaurants for checking out the menu and placing an order. We find them in libraries where you can use this interactive technology to find the book you want to read. We even carry the tech around in our pockets in the form of smartphones and laptops. Think about it.. life today without touchscreen displays would seem completely impossible to the younger generation, wouldn’t it? So why is this technology so important today? One of the most important advantages of touchscreen displays is the ease of use that it offers. Computers were always a bit difficult, especially for people who were new to the technology. Command sequences and GUI formats were difficult to get the hang of which means if you are using a device for the first time, there would be some difficulty faced. But touch technology came in as a breath of fresh air, making everything about modern computing intuitive and easy to follow. You would wonder how does this technology work. From the point of view of the user, it is simple computing, no different from using a mouse or touchpad on your laptop. You use the power of touch to get things done, select files and applications and initiate command sequences. But the major difference here is that the only input device involved in this entire scenario is the touchscreen display. A user is presented with an interface that he/she can use to interact with the computer through touch signals. This screen can be as small as the display of your iPod or as large as the Mission Control monitors we have all seen at NASA. From the point of view of technology, touchscreen displays are nothing short of genius. Basically, a touch screen is actually just another piece of hardware. A thin film of touch sensitive lamination (clear) is placed over the computer monitor; this is then wired into the computer. The pressure from your finger is transformed into an electric signal, which is then sent to the CPU. In some cases, this touch input can be given to the computer through the use of devices like a stylus while in others, actual physical contact with human screen is necessary to make the technology work. Whether it is industrial level processing or everyday computing, touchscreen displays have made themselves an indispensible part of our world. The very idea of going back to push button input system seems so laughable and frustratingly slow today. The technology has been made to be very affordable and sturdy, making it an ideal choice for various kinds of applications. There are a number of popular manufacturers creating touchscreen displays today. Some of the most popular are Planar, GVision, Megavision, NEC and HP. To know more, visit Gvision-usa.com.
