A plasma touch screen display system is usually equipped with an open frame touch screen display. This type of display provides a clearer picture because the light which is reflected from the display goes through the “translucency” feature. When you place your finger on the screen, you will be able to see the text clearly. This type of screen offers better clarity than a CRT or an LCD touch screen display. The reason for this is that the liquid crystal displays (LCD) have a curved liquid crystal media covering them. It is not possible for a CRT display to be as clear as an open frame display due to air bubbles.
An open frame touch screen display is usually made with a variety of materials including glass, plastic, aluminum and many others. There are even some types that are manufactured from wood. Among these, the most expensive but also the most popular is the faytech lcd displays. The faytech company was introduced in 1990 and the name was derived from a type of metal that was used in the manufacturing of this type of screen. Other materials include acrylic, aluminium, and other metals.
These monitors are much more costly than the typical CRT type because it is heavier and thicker. Because of its thickness, it requires that the technician drill holes in the desktop so that the liquid crystal material can be placed into the frame. Because of this extra work, these open frame touch screens are normally priced higher than regular CRTs. One advantage of these monitors is that they can support a wide variety of languages. Although the fonts are large, it is possible to adjust the size to the size of the text so you can view the text in different languages.
Another type of display that is used today are the LED backlight monitors. These kinds of touch screen displays come in two varieties, flat panel and led backlight. The flat panel monitors are usually cheaper than the LED ones because they do not need the extra steps in manufacturing the liquid crystal material. Most of the time, the flat panel monitors have larger screens which have smaller font sizes.
One of the disadvantages of the LED backlight type of touch screens is that their light cannot be dimmed. Another disadvantage is that the contrast ratio of LED backlight is not as good as that of the CRT type. Most manufacturers produce LED touch screens that have the ability to be connected to a computer or a video game system.
There are several manufacturers of open frame touch screen monitors. Some of the names include Wacom, Presto and JML. However, when you go out shopping for one, you need to compare the prices and features so you get the most affordable kind. You can use the internet to compare stores. It would be best if you could get the display unit from a store where you know that you can return it if you are unsatisfied.
