Surface capacitive touchscreen technology When a finger comes into contact with the screen, the ratios of the electrical currents change and the computer is able to detect the touch points. A projected capacitive is composed of a sheet of glass with embedded transparent electrode films and an IC chip, which creates a three dimensional electrostatic field. Is similar to Surface Capacitive, but it offers two primary advantages: in addition to a bare finger, it can also be activated with surgical gloves or thin cotton gloves and it enables multi-touch activation (simultaneous input from two fingers). ! Projected Capacitive Touchscreen – large touchscreens SAW monitors offer easy use and high visibility. SAW monitors can be activated by a finger, gloved hand, or soft-tip stylus. This allows the receiving transducer to locate the touch point and send this data to the computer. When the panel is touched, a portion of the wave is absorbed.

SAW (Surface Acoustic Wave) touchscreenġ9 inch touchscreens - touch screen monitors utilize a series of piezoelectric transducers and receivers along the sides of the monitor’s glass plate to create an invisible grid of ultrasonic waves on the surface. The point of contact is detected by this change in voltage. When a user touches the screen, the two metallic layers make contact, resulting in electrical flow. A resistive touch screen monitor is composed of a glass panel and a film screen, each covered with a thin metallic layer, separated by a narrow gap. Indestructible and works under maximum conditions. Has been the most widely used touch technology. Interactive Touch Screen Kiosk Technology 5-Wire Resistive Touchscreen

TDS TOUCH– touchscreens of all technologies and design.Touch Screen Monitor – Interactive Touch Tablet 55″ to 98″.Insight Touch – touchscreens products from 10″ to 98″ customized and supported in US.Mimo Monitors – smaller form factor touchscreen monitors, displays, and tablets.AUO – All types of touchscreens and displays.In 2019 we added contactless touchscreens. However, SAW, projected capacitive and analog resistive make up 90% of the total market. The top touch technologies are projected capacitance, analog resistive, surface capacitive, infrared (IR), and surface acoustic wave (SAW). At one time it was considered fully optional, now it is pretty much a given (though some keyboard apps still exist). The interactive screen or touchscreen display is the primary interface for self-service kiosks.
