  • What is LCD Capacitive Touch Screen

    • The choice of capacitor or resistor depends largely on the object touching the screen. If it is a finger touch, the capacitive touch screen is a better choice. If a stylus is needed, whether plastic or metal, a resistive touch screen will do. A capacitive touch screen can also use a stylus but requires a special stylus to work with it.

  • Resistive Touch vs. Capacitive Touch - Crystalfontz LCD Blog

    Capacitive touchscreens are a little more complied. Capacitive touchscreens work by registering a change in an electrostatic field on the screen when touched with an adequately capacitive object, like a finger. Gloved fingers or a stylus may be used, but they must have conductive materials to …

  • How to Choose Between Capacitive & Resistive Touch Displays

    Unlike the resistive touch displays that relies on mechanical pressure applied to the surface, capacitive touchscreen makes use of human body’s natural conductivity to operate. These screens are made of transparent, conductive material—usually ITO—coated onto a glass material.

  • Avoiding EMI in capacitive touch screens

    “The capacitive touch screen also sends small capacitance variations created by the finger touch to the analogue signal conditioning circuit,” says Noviello. “Like the MEMS case, these variations are very small, typically in the range of femto-Farads (10-15F) but the panel capacitance …
