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.
