Open Frame Touchscreen Monitors – An Overview
In the world of touch screen monitor technology, open frame touchscreen monitors are one of the latest products. There are several differences between the two, as it relates to how they operate. Although they may seem similar to other types of screen monitors, there are actually several important differences that really make them different. The first difference is that these models use an open frame design, which makes them unique. While they do share some similarities with resistive and capacitive touchscreen monitors, there are clear differences in the way that they operate and what they offer you.
One of the primary differences between the open frame touchscreen monitors that are available is that they use a touch screen instead of a physical keypad or buttons. This can make them much easier to use than resistive and capacitive touch screen monitors. Capacitive touch screen monitors force you to constantly press and hold the button on the screen while you are using it, which can be frustrating for people who have short attention spans. The lack of a physical keypad means that you have to make sure that you always have your finger on the button, making it difficult to fidget and tapping the screen in awkward situations.
Resistive touch display technology has historically been the preferred type of touch display, but the advances in the battery life of modern tablets and smartphones have made it possible for them to run on open frame monitors. Because of the increased battery life of these devices, you will find that they are much more durable and reliable than resistive touch screens. In addition, resistive touch display monitors are no longer prone to overheating, which can reduce their overall efficiency and make them less effective than modern touch screen devices. If you need a touch display monitor with the longest life and the best reliability, then an open frame touchscreen monitor is the best option for you.
Capacitive touch screen monitors operate on a different principle. They operate based on electrical signals, rather than light or sound. The main advantage to using capacitive touch screen monitors is that they are extremely responsive. You can scroll up and down menus and watch video clips in full operation, because their response time to movement is so fast. However, they require constant pressure from the user in order to register a point of contact with the screen and so are not very practical for high touch interface situations.
On the other hand, a touchscreen that operates on a traditional liquid crystal display (LCD) technology can provide better accuracy and greater functionality. Capacitive touchscreen monitors work based on a “class” of technology which includes resistive, capacitive and infrared. A resistive touchscreen monitor operates based on physical signals, and responds to pressure and other physical movements. Capacitive touchscreens, by contrast, respond to electrical signals. Some use digital signal outputs to communicate with external devices, and some use infrared light to communicate with the internal liquid crystal screen.
Modern resistive touchscreen technologies include technology called capacitance. It is this component that provides the information needed to interface with a capacitive touchscreen. Capacitive monitors respond to pressure and other physical movements, using the power of charged particles to change the state of the screen’s surface. That is why they tend to be sensitive to finger motion. So if you use a finger to gesture, say to zoom in and out of an image, the result is a point of light detection within the pixel.
Capacitive open frame touch screens used to be among the least expensive available, but they were also among the most troublesome to maintain. When a cap of the device wore off or the power outlet was unplugged, the screen would reset itself, requiring the user to reboot in order to see it working properly again. Users also complained about the fact that the life of the cap and the life of the battery decreased significantly over time. Some users even began to notice decreased response times and screen glare as the battery became older. Manufacturers responded to customer concerns by developing stronger cap materials and harder-duty, long-lasting batteries.
Recently, manufacturers have begun designing open frame touchscreen monitors that utilize a microprocessor to automatically detect the orientation and extent of the viewing angle, and to control the display accordingly. These newer generation open frame monitor devices use a microchip or microelectronic circuit to sense the orientation and extent of the viewing angle, and to control the display so that it appears at its most effective level when the user is actually looking at it. They are generally smaller than their capacitive cousins, but some are as small as one-third of an inch. The new microprocessor based monitors eliminate all the problems associated with the resistive and capacitive types of touch screen. These newer generation technologies are also more affordable, efficient, and reliable than ever before.
