Touch screen principle technical screen principle:

The main part of the resistive touch screen is a resistive film screen that fits perfectly with the surface of the display. This is a multilayer composite film with a layer of glass or hard plastic flat as a base layer with a transparent metal oxide (ITO indium oxide , Transparent conductive resistance) conductive layer, covered with a layer of the outer surface hardening treatment, smooth anti-rubbing plastic layer, its inner surface is also coated with a layer of ITO coating between them there are many small (less than 1 / 1000 ") transparent isolation points separate the two conductive layers. When the finger touches the screen, the two conductive layers have contact at the touch point position, the controller detects the contact and calculates (X, Y ), And then according to the way the mouse to simulate the operation. This is the touch screen technology, the most basic principle. Resistance screen since entering the market, on a stable quality, reliable quality and high environmental adaptability occupy the majority of the market Especially in the field of industrial control, due to its high environmental and high demand, it shows the unique characteristics of the resistive screen, so that its products in the same kind of touch products account for 90% of the market, has become the mainstream products on the market. G-Touch the latest fourth-generation resistance technology Touch screen and other resistive screen products is different: it is the glass substrate, making the higher transmittance, the refractive index refraction is more The same time, the uniform coating of the conductive layer of the glass substrate to adsorption on the touch screen on the electrostatic particles unloaded through the ground to ensure a more accurate positioning touch, more sensitive to completely remove the charged particles caused by excessive drift phenomenon , The positioning is not allowed, the reaction rate is slow, making it longer life (physical determination of a single point of continuous use up to 15 years), and have the maintenance-free capacity, anti-scratch degree has also been greatly improved. Excellent quality and reasonable prices of products.
