TOPIC: -Touch screen monitors area device by which we give inputs and take outputs as informationwithout using any other external device. Instead of using a keyboardor mouse.A touch screen is adisplay which can detect the presence and location of a touch withinthe display area. The term generally refers to touch or contact tothe display of the device by a finger or hand. Touch screens can alsosense other passive objects, such as a stylus.The touch screen has twomain qualities. First, it allows you to interact with what isdisplayed directly on the screen, where it is displayed, rather thanindirectly with a mouse (computing) or touchpad. Secondly, it letsone do so without requiring any intermediate device, again, such as astylus that needs to be held in the hand.Touch screen monitors areused in a variety of different applications including POS (point ofsale) cash registers, PDA's (personal digital assistants), ATM's, carnavigation screens, cell phones, gaming consoles and any other typeof appliance that requires you to input and receive information.Types of technologyavailable in Touch Screen. The commonly used are underneath: -Resistive Touch monitorsA resistive touch screenmonitor usually has a coat of very thin electrically conductive andresistive layer of metal. When pressed, the change in electricalcurrent can be measured and the input processed by a computer. Whilevery affordable they only offer about 75% clarity, they can also beeasily damaged by objects that are sharp. Resistive touch screenmonitors are the most popular types of touch screen monitors usedtoday. They are usually not effected by dust or liquids which makethem very reliable.Surface Wave Touch ScreenMonitorsSurface wave touch screenmonitors use ultrasonic waves to process inputs from the screen.Ultrasonic waves flow over the touch screen, when a person touchesthe pad at a specific location, the wave is absorbed and immediatelyprocessed by the computer. While not as common as resistive touchpanels, they are used in certain applications. Dust and water cancontaminate a surface wave touch screen so it is important to keepthe screens properly maintained.Capacitive Touch ScreenMonitorsCapacitive touch screensare coated with indium tin oxide. This material provides a continuouscurrent across the screen. The current is precisely controlledthroughout the touch pad and can be measured by the computerprocessor, when touched; the screen is able to send the processorspecific coordinates to input information correctly. It is importantto note that specific objects can only be used on capacitive touchscreens. You can not use a stylus or a pencil for instance; usuallyyou will need a bare finger. Capacitive touch screens have highclarity and are not affected by dust or liquids.Infrared Touch ScreenMonitorsThere are two types ofInfrared touch screen monitor screens, the first reacts to infraredor thermal waves (heat), unfortunately this technology is slow anddoes not work well with cold hands or objects. The second type ofInfrared touch screen monitors use vertical and horizontal infraredsensors around the perimeter of the touch screen. Creating a grid,the touch screen is able to pinpoint the exact location of where thescreen has been touched and send that information to the computer forprocessing. Infrared touch screen monitors are very durable and areused for industrial and military applications.There are many differenttypes of touch screen technology available. The most common typesinclude: Resistive, Surface Wave, Capacitive and Infrared.Beganto ElectronicComponents Article Tags: Touch Screen Monitors, Surface Wave Touch, Wave Touch Screen, Capacitive Touch Screens, Infrared Touch Screen, Touch Screen, Screen Monitors, Touch Screens, Resistive Touch, Surface Wave, Wave Touch, Capacitive Touch, Infrared Touch
