interactive touch screen projector.The base layer of the five-wire resistive touch screen applies the voltage fields in both directions to the conductive working surface of the glass through a precision resistance network. We can simply understand that the voltage fields in both directions work on the same working surface in a time-sharing manner. The outer layer of nickel-gold conductive layer is only used as a pure conductor. The position of the touch point is measured by the method of detecting the X-axis and Y-axis voltage values ??of the inner ITO contact point in time after touching. A five-wire resistive touch screen requires four leads on the inner layer of ITO, only one outer conductor, and five leads on the entire touch screen. Its service life is no less than 30 million times with a single touch. Its disadvantages are high prices and high environmental requirements.
