Touch Screen Monitors |
Touch Screen MonitorsTouch Screen Monitors are an integral part of restaurant, hospitality, medical, or the service industries point of sale systems. Employees can touch the portion of the screen instead of clicking, saving time and minimizing clutter around the POS station. POSGuys carries a wide variety of touchscreen monitors from manufacturers such as Elo, Pioneer, POS-X, G-Vision, and Microtouch.
Touch Screen monitors use different technology in order to trace the touches, the most popular being resistive and capacitive.
A resistive touch screen panel is made up of several layers, the most important being two electrically conductive layers that when pressed down upon with an object (such as a finger), the two layers become connected at that point. This causes a change in the electrical current which then registers as a touch and is sent to the controller for processing.
In most cases using a resistive touch screen works best and is the most popular technology for restaurants because the surface of the monitor can get a little dirty or sticky but still work efficiently.
The second most popular technology is capacitive. A capacitive touch screen uses an insulator, such as glass, coated with a transparent conductor. Since the human body is also a conductor, touching the surface results in a distortion of the electrostatic field, changing the capacitance.
Often times a stylus won't work on the capacitive touch screen, and if using this type, the screen must be kept fairly clean in order for it to work effectively. However, these touch screens are known to have a sharper, cleaner picture.
Touchscreens are available both in an LCD and CRT variety. LCD is the most popular since it takes up less area, looks better, and in many cases is wall mountable via vesa mount holes.
Touch monitors are available from 10 inches up to full HD 1280P LCD monitors, but the most popular sizes are the 15 inch and 17 inch sizes.
