Lets talk about our Capacitives touch screen :
What is a capacitive touchscreen?
A capacitive touchscreen is a control display that uses the conductive touch of a human finger or a specialized input device for input and control .
How does a capacitive touchscreen work?
Capacitive touchscreen panels must be touched with a finger, a special capacitive pen or a glove. That's because the panel is coated with a material that can store electrical charges. The change in capacitance signals the location of the touch. This differs from resistive and surface wave panels, which can sense input from a finger or stylus.
When a capacitive panel is touched, it draws a small charge to the point of contact, becoming a functional capacitor. The change in the electrostatic field is measured to find the location. In some designs, circuits located at each corner of the panel calculate the charge and send the information to the controller for processing. In multitouchscreens, sensors are arranged in a grid to enable more complex input.
Techopedia Explains Capacitive Touch Screen
The capacitive touch screen is built with an insulator-like glass coating, which is covered with a see-through conductor, such as indium tin oxide (ITO). The ITO is
attached to glass plates that compress liquid crystals in the touch screen. User screen
Activation generates an electronic charge, which triggers liquid crystal rotation. Capacitive touch screen types are as follows:
Surface Capacitance: Coated on one side with small voltage conductive layers. It has limited resolution and is often used in kiosks.
Capacitive vs. resistive touchscreens
Resistive touchscreen devices sense the application of pressure, which causes two conductive layers to come into proximity. Capacitive touchscreens don't react to external factors such as temperature, humidity or light, enabling them to function without interference from these variables. They also provide higher levels of clarity, precision and accuracy, even with minimal pressure or touch.
Projected Capacitive Touch (PCT): Uses etched conductive layers with
electrode grid patterns. It has robust architecture and is commonly used in point-of-sale transactions.
PCT Mutual Capacitance: A capacitor is at each grid intersection via applied voltage. It facilitates multitouch.
PCT Self Capacitance: Columns and rows operate individually via currentmeters. It has stronger signal than PCT mutual capacitance and functions optimally with one finger.Other touch screen technologies include resistive, surface acoustic wave (SAW) and infrared (IR).
