At present, many touch display screens on the market use capacitive touch screens. Why are 7 pcap capacitive touch screen so popular?
The capacitive touch screen is a transparent special metal conductive material pasted on the glass surface. When a finger touches the metal layer, the capacitance of the contact changes. Causes the frequency of the oscillator connected to it to change. Information can be obtained by measuring the change in frequency to determine the location of the touch. It uses the electric field of the human body to conduct electricity, thereby forming an electric current. This current flows from the electrodes on the four corners of the touch screen to form four currents. The controller obtains the position of the touch point through the precise calculation of the ratio of these four currents.
capacitive touch screen to achieve multi-touch, rely on the electrode to increase the mutual capacitance. Simply put, it is to divide the screen into blocks. Setting up a group of mutual capacitance modules in each area works independently. Therefore, the capacitive screen can independently detect the touch situation in each area and process it. Simple implementation of multi-touch. It can reach 99% accuracy and has a response speed of less than 3ms.
Therefore, it charaterize the capacitive screen touch technology by its novelty, high reliability, durability and flexibility. It is becoming more and more popular among consumers and manufacturers. The capacitive touch screen we have launched covers 3.5-64 inch capacitive screen. Covering various application scenarios from basic to high-end. We increasingly use this technology in consumer electronics, medical, industrial automation, and computer peripherals.
