Durable Usb Powered Touch Screen / 27 Inch Waterproof Touchscreen Display
Usb Powered Touch Screen Structure & Operating Principle:
►There is electrode pattern printed along the edges distributes a low voltage filed over the conductive layer.
►The human body is also an electrical device which has stored electrons and therefore also exhibits capacitance.
►When a finger touches the screen and draws a minute amount of current to the point of contact ,creating a voltage drop.
►The current flow from each corner is proportional to the distance to the touch point. During a touch ,capacitance forms between the finger and the sensor grid. The touch location is calculated from the changing electrical characteristics of the sensor grid.

Usb Powered Touch Screen :
Capacitive touch screen are built with two parallel layers of ITO but, but unlike the old and cheap resistive touch panels, the ITO layers in a projected capacitive touch panel are sealed between two sheets of glass by an optically clear adhesive.
♦any point can withstand more than 50 million times touch
