                                                                                                     Definition of capacitive touch screen


The structure of the capacitive touch screen is mainly to coat a transparent film body layer on the glass screen, and then add a protective glass outside the conductor layer. The double glass design can completely protect the conductor layer and the sensor.
The capacitive touch screen is coated with long and narrow electrodes on the four sides of the touch screen, forming a low-voltage AC electric field in the conductor. When touching the screen, due to the electric field of the human body, a coupling capacitance will be formed between the finger and the conductor layer, and the current from the electrodes on the four sides will flow to the contacts, and the current strength is proportional to the distance from the finger to the electrode. The controller behind the touch screen is then It will calculate the proportion and strength of the current, and accurately calculate the position of the touch point. The double glass of the capacitive touch screen can not only protect the conductors and sensors, but also effectively prevent external environmental factors from affecting the touch screen. Even if the screen is stained with dirt, dust or oil stains, the capacitive touch screen can still accurately calculate the touch position.

The capacitive touch screen is to paste a layer of transparent special metal conductive substance on the glass surface. When a finger touches the metal layer, the capacitance of the contact will change, causing the frequency of the oscillator connected to it to change. By measuring the frequency change, the touch position can be determined to obtain information. Since the capacitance changes with temperature, humidity or grounding conditions, its stability is poor and it tends to drift. This kind of touch screen is suitable for the debugging stage of system development.

The difference between capacitive touch screen and ordinary resistive touch screen
Generally speaking, a capacitive touch screen is a human-computer interaction method that supports multi-touch. Ordinary resistive touch screens can only perform single-point touch.
For example: Apple iphone is a capacitive touch screen, you can use both hands to touch the screen at the same time to operate, browse and zoom in webpage pictures, etc.
Nokia 5800, n97; HTC d600 s900, etc. are resistive touch screens, which can only be operated with a single point.
