types of capacitive touch screen

touchscreen is made up of materials such as alloys or indium Siena oxides (ITO), which are stored in a miniature static grid with a thinner root than the hair. When the finger hits the screen, it absorbs a small amount of current from the point of contact, causing the pressure drop of the corner electrode, using the method of sensing the weak current of the human body to achieve the purpose of touch. (This

First, the resistance screen:The screen part of the resistive touch screen is a multilayer composite film. A layer of glass or plexiglass serves as the base layer, and the surface is coated with a transparent conductive layer (itofilm ), the top is covered with a plastic layer with a surface hardened and smooth scratch resistance. Its inner surface is also coated

Difference between capacitive screen and Resistive Screen 1. resistive touch screen　　① They are a completely isolated work environment, not afraid of dust, water vapor and oil pollution② It can be touched by any object and used for writing and painting. This is their great

an electric charge, including human skin. (The charge of the body) a capacitive touchscreen is made up of materials such as alloys or indium Siena oxides (ITO), which are stored in a miniature static grid with a thinner root than the hair. When the finger hits the screen, it absorbs a small amount of current from the point of contact, causing the pressure drop of the corner electrode, using the method of s

Recently, I often hear from Members that the Android mobile phones, such as Motorola milestones, do not respond to touch and screen failures. In this case, do not panic. In fact, this phenomenon is normal on the touch screen mobile phones. This requires us to pay more attention to maintenance and maintenance when using

Touch screen type: according to different sensing methods, touch screen can be divided into four categories: resistance type, Capacitive Type, infrared type, and ultrasonic type. Among them, the current market prospect of Resistance Type and

for the design needs, you can also design MCU-based A/D port to realize the touch IC. Five, SJT5104 touch IC Introduction 1. Basic Introduction The SJT5104 is a low-cost, high-reliability capacitive touch sensing IC with 4 touch-sensitive keys and 4 direct output ports, bui

Working principle Resistance touch screen: composed of multilayer transparent conductive plate, two layers of transparent metal conductive layer used to identify the touch signal can identify the pressure signals from the stylus, nails, and any hard objects, and normally the two layers of transparent metal conductive layer are in mutual insulation state, when th
