How to make a touch screen?
In recent years, more and more devices are equipped with touch screens. However, in order to enjoy the convenience of touch controls, it is not at all necessary to buy a “fresh model” of a device, because even a traditional display can easily be turned into a touchscreen. So, this article will discuss exactly how to make a touch screen at home, without any special effort.
Laptop and PC display
At the first stage, you will have to purchase a special Duo Digital gadget developed by Korean engineers. With it, you can turn any ordinary display, up to 22 inches, into a touch screen. The presented device is a special scanner that is installed at the top of the monitor. It tracks user manipulations and sends data about them to a computer for processing. The second part of the Duo Digital system is a handle that replaces the mouse. It, like the manipulator familiar to all of us, has two control buttons.
Continuing the conversation about how to make a laptop screen touch, it should be said that the Duo Digital system is inexpensive - about 40-50 dollars for one set.Therefore, this approach to the modernization of the old laptop is quite economically justified. By the way, the price of the device does not depend on the diagonal of a particular display. The main thing is that your device, as already mentioned, does not have a matrix of more than 22 inches.
After you have purchased the Duo Digital system, fix the scanner to the top edge of the monitor. To do this, it provides a special mount, similar to the webcam lock. It is advisable to install the scanner exactly in the middle of the screen width. Next, turn on Duo Digital and install special software on your computer. All the necessary drivers are bundled with Duo Digital, so there should be no problems with finding software. At the next stage, we make individual settings and everything - your laptop or monitor turned from ordinary into touch!
As for how to make the touchscreen of the phone, there are a few more difficulties. And the main one is the price. For mobile phones and smartphones, there are also devices like Duo Digital. However, they are unnecessarily expensive. So, for example, at the end of 2007, the well-known Finnish manufacturer of communication equipment, Nokia, released a special Bluetooth pen.Using this device, you could write messages, phone numbers, notes, and other information on a standard Bluetooth phone without using a traditional keyboard. In 2008, this pen appeared on the market of Russia and Ukraine. However, out of the price of 240-280 dollars, this gadget has not gained much popularity. Indeed, for such money nowadays, you can buy two full-fledged sensory phones at once and not indulge yourself with similar accessories from Nokia.
Now you know how to upgrade your device and how much it costs to make a touch screen for a regular monitor, phone or laptop.
