8Inch Projected Capacitive Touch Screen
Capacitive touch screens have better transmittance and clarity than four-wire resistive screens.
Certainly not compared to a surface acoustic screen or a five-wire resistive screen.Besides, the light transmittance of the four-layer composite touch screen with capacitor technology is not uniform to each wavelength light, which has the problem of color distortion. The reflection of light in each layer also causes the blurring of image characters.In principle, the capacitor screen USES the human body as an electrode of a capacitor element. When a conductor is close to the capacitor coupling with the ITO working face of the sandwich, sufficient capacitance value will be generated, and the flowing current will be enough to cause the wrong operation of the capacitor screen.

We know that the capacitance value, although inversely proportional to the distance between the poles, is directly proportional to the relative area and is also related to the insulation coefficient of the medium.Therefore, when a large palm or carrying conductor came near the capacitance screen not touch can cause the misoperation of capacitance screen, in the humid weather, this situation is particularly serious, walking live display, palms to display within 7 cm or body to display within 15 cm can cause misoperation of capacitive screen.
Another drawback of capacitive screens is that they do not respond to touch with a gloved hand or a hand-held non-conductive object because of the added insulation.The main disadvantage of capacitor screen is drift: when the ambient temperature and humidity change, and the ambient electric field changes, the capacitor screen will drift, resulting in inaccurate.For example, when the display temperature rises after starting up, it will drift. When the user touches the screen, the other hand or one side of the body will drift close to the display.The large objects near the capacitive touch screen will drift back after being moved, and the drift will also be caused if people come around to watch.The reason for the drift of capacitive screen is due to the inherent shortage of technology. Although the environmental potential surface (including the user's body) is far away from the capacitive touch screen, it has a much larger area than the finger, which directly affects the determination of the touch position.
