Capacitive Touch Panel Display Introduction

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.

Capacitive Touch Panel Display Structure & Operating Principle:

►Capacitive touch screen is a piece of 2 layer of compound glass with double side transparent conductive coating that conducts a continuous electrical current across the sensor.

►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.

Capacitive Touch Panel Display Application:

►Touch Monitor.

►Information Kiosks.

►Gaming, Lottery ect.

►Multimedia marketing.

►Banking / Fanancial System.

►Touch Table.
