In the past, a resistive touch screen monitor was basically a display unit that consisted of a flat, resistive glass pane that was covered with a thin plastic and a small resistive metal layer. These two layers are kept separate by tiny spacers (planar objects placed between two or more flexible sheets of glass so as to maintain a uniform thickness between the glass and the metal.) The plastic used in touch screen displays included paper-based adhesive that allowed the use of different adhesive on the touch screen itself. Those displays were good enough but they lacked something important: The ability to be transparent.
When people started using touch screen monitors, the available media players had only the simplest form of display. There were separate circuits that controlled video and audio output and input, and an analog signal processor (ASIC) that handled the decoding of those signals. Even though it was clear that there would need to be some changes to how touch panels worked, these changes didn’t materialize until the introduction of new, modern technology.
When touch screen monitors first appeared, their main appeal was that they provided a very cheap alternative to full computer monitor systems. Touch monitors could be purchased for as little as twenty dollars, a huge decrease in today’s economic situation. They also had the advantage that they didn’t require a dedicated graphics card; you only needed a small screen to make a computer work with one of these. This meant that a single touch surface could serve the purpose of many monitors, making them much more affordable. Additionally, a whole new generation of smaller and cheaper touch screen monitors started appearing, which made it even easier for the consumer to purchase a monitor.
Touch screen panels began to appear in different shapes and sizes. The flat panels of early touch screen display were popular, but as touch screen panel technology evolved, these started to disappear altogether. Later on, companies started building touch screen panels which had the same thinness and convenience of the earlier flat panels, but also included a resistive or ionic layer underneath to help increase the power draw of the unit. This was done in order to keep the touchscreen from getting too hot, something that was becoming a problem as the years went on. Finally, some manufacturers started building devices with a built in, resistive layer, in which the user simply pushes a certain part of the screen, and it quickly responds by pulling back the rest of the touchscreen.
So now, we find that touch screen monitors are used by just about everyone. We use them for work, pleasure, and entertainment. Because touch screen monitors have become so common, and because manufacturers are constantly coming up with newer, more advanced models, the price for them has come down significantly. You can now get a good quality flat panel touch screen monitor for just a few hundred dollars. Many people still decide to buy brand new monitors, but for the most part, touch screen monitors can be had just as cheap as ever.
Some touch screen monitors, like the ones mentioned above, include an image processing system inside of them which is used to speed up the operation of the monitor and make it easier to use. Some people choose this option because the image processing unit is often much faster than the unit itself. Some people will also choose this option because they want to save a little money. However, this is not always the best option. There are many different technologies out there that can improve the operation of the touch panel technology, and one of these is low queue times.
If you look at the specifications for a lot of the touch screen monitors that are out there, you will see that they mention a touch panel technology called Bezel Control. It should not surprise you to learn that this Bezel Control is the main reason that there is such high dropout rates from some companies. When you are looking at a Bezel Control monitor, be sure to pay very close attention to the bezel that runs around the monitor. While this may seem to make sense, the manufacturers who use this bezel in their monitors are actually losing money in this process. The bezel is actually slowing down the image quality because the slower the bezel is, the lower the refresh rate of the monitor is, and therefore the more time it takes to update the image.
There is one last type of technology which is used in some very expensive touch screen monitors, and that is something called Indium Tin Oxide (ITO). This is a special type of metal which has very sensitive ionic properties. What this means is that the more of this material there is to the touch-screen monitor, the better the image quality will be. Of course, when you are talking about the image quality of a touchscreen monitor, this means the difference between using a touch screen monitor with or without ITO will be quite noticeable, so make sure that you are clear on your needs before you buy a monitor.
