Resistive touch screen technology works

The main part of the resistive touch screen with a display surface is very thin with a resistance screen, which is a multilayer composite film, it is a layer of glass or hard plastic plate as the grass surface with a transparent metal oxide diagram (ITO indium , a transparent conductive resistance) conductive layer, above the outer surface of the cover with a layer of hardened, smooth anti-friction plastic layer, its inner surface is also coated with a layer of ITO coated, among them many of the small (less than 1 / 1000 inches) transparent separation point two conductive layers separated by insulation. When a finger touches the screen, two conductive layers in the touch point there will be a touch controller to detect and calculate the exposure (X, Y) position, according to simulate a mouse operation. This is the resistive touch screen technology of the basic principles. Graphic LCD Module
Resistance screen since entering the market, it is to stabilize the quality, availability and environmental quality * highly adaptable occupy the majority of the market. Especially in the industrial areas, due to its high demand environment and conditions, but also shows the uniqueness of the resistive screen, touch its products in similar products occupy 90% of the market volume, has become the market mainstream products. Its biggest feature is not afraid of oil, dust, water.
G-Touch latest fourth-generation resistive touch screen technology and other resistive screen product differs in that: It glass substrate board, making a higher transmittance, reflectance index is more suitable for the user. Meanwhile, the uniform coating of the glass bottom of the conductive layer adsorbed on the touch screen particles by electrostatic uninstall ground to ensure a touch more accurate positioning, more sensitive, completely remove the charged particles caused by excessive drift, positioning allowed, the reaction is slow, making it longer life (physical measurement single point of continuous use up to 15 years), and have the ability to maintenance-free, anti-scratch degree has also been greatly improved. Indeed is a superior quality products at reasonable prices.
Four-wire resistive screen features: COG LCD Display
■ High-resolution, high-speed response.
■ Surface hardness treatment, reduce abrasion, scratch and anti-chemical treatment.
■ with glossy and matte.
■ a correction, high stability, and never drift.
Four-wire resistive analog technology work two transparent metal layers each layer increases 5V constant voltage: a vertical direction and a horizontal direction. Total need four cables.
Five-wire resistive screen features:
■ high-resolution, high-speed transmission response.
■ surface hardness, reduce abrasion, scratches and chemical treatment visit.
■ 30 million times the same point contact can still be used.
■ conductive glass substrate for the media.
■ a correction, high stability, and never drift.
Five-wire resistive analog technology to the two directions of the voltage applied to the resistor network by * in that the layer of the metal layer, * and the detected current detection voltage as measured by a method of the touch point, as only the outer layer ITO conductor layer, totaling five cables.
