7 inch touch screen music system

7 inch touch screen music system.Capacitive touch screens have high resolution and are suitable for various types of displays. The capacitive touch screen design uses the principle that the ac signal coupling between the two conductors is better than the dc signal coupling. The core of this special technology is an all-glass touch screen that is conductively coated with a transparent thin film that is welded to its surface. The protective glass coating on the conductive coating protects and seals the sensitive parts. The precision printed electrode pattern on the edge of the glass screen evenly distributes the low voltage ac field on the conductive layer. When the finger is in contact with the screen surface, it capacitively couples with the voltage field and flows a trace of current into the contact point. The key components in a capacitive system are radio frequency (RF) sources that operate at low megahertz and provide output circuits for each screen angle. Each output circuit includes a current measurement circuit. The current from each corner is proportional to the distance of the contact point of the finger, and the touch screen controller measures the current rate to set the contact point.
