This kind of conductive glass is used as the base layer of the second-generation five-wire resistive technology touch screen. Not only that, the five-wire resistance technology adds 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 the two directions are applied to the same working surface in a time-sharing manner. The outer nickel-gold conductive layer is only used as a pure conductor. After touch, the position of the touch point is measured by the method of detecting the voltage of the inner ITO contact point and detecting the conduction current. The five-wire resistive touch screen requires four leads on the inner layer of ITO, and only one lead on the outer layer as a conductor. A total of 5 cables are needed to reach the controller. Because the outer nickel-gold conductive layer of the five-wire resistive screen is not only ductile, but also only used as a conductor. As long as it continues to be in two halves, it can still continue to complete its mission as a conductor; and the heavy-duty inner layer ITO is directly connected to the base layer The glass is combined into a whole to become conductive glass, and conductive glass naturally does not have all the disadvantages of plexiglass as the base layer. Therefore, the service life and light transmittance of the five-wire resistive screen has a leap compared with the four-wire resistive screen: the touch life of the five-wire resistive screen is 35 million times, and the four-wire resistive screen is 21 million times smaller. There is no risk of installation for the five-wire resistive touch screen. At the same time, the ITO layer of the five-wire resistive screen can be made thinner, so the light transmittance reaches 75% and the clarity is higher.
Whether it is a four-wire resistive touch screen or a five-wire resistive touch screen, they are a working environment that is completely isolated from the outside world, not afraid of dust, water vapor and oil. It can be touched with any object and can be used for writing and drawing. It is more suitable The use of limited people in the field of industrial control and in the office. The common disadvantage of resistive touch screens is that because the outer layer of the composite film is made of plastic materials, people who do not know too hard or use sharp objects to touch may scratch the entire touch screen and cause it to be scrapped. However, within the limit, the scratches will only damage the outer conductive layer. The scratches on the outer conductive layer have nothing to do with the five-wire resistive touch screen, but are fatal for the four-wire resistive touch screen. In addition, organic solvents cannot be used to clean the screen.
Due to the inherently stable design, the five-wire resistance is the most accurate and reliable technology, and it can be touched without any malfunction. The number of operations at a certain point can reach 35 million. This type of touch screen has the longest service life than other resistive screens, but the plastic surface material is easy to scratch and is only suitable for professional use. When environmental conditions change, there is no need to re-calibrate the product.
