hp 24 inch touch screen all in one.Dr. Samuel C. Hurst proposed the concept of electronic touch interface in 1971, and the earliest touch screen began to appear in 1974. Early related patents almost always focused on resistive technology for detecting pressure. Gradually, other technologies such as capacitive, surface acoustic wave technology, and infrared beam blocking have found their place in their respective applications. For cost-sensitive consumer applications, especially portable devices using small touch screens, resistive touch screens still dominate. Acoustic surfaces and infrared-type touch screens are obviously too expensive for these occasions, while traditional capacitive technology is subject to poor long-term stability, susceptibility to moisture erosion, resistance to abrasion, and EMC (electromagnetic compatibility) or other external factors Caused by a series of shortcomings such as malfunction. However, resistive touch screens also have their limitations, and capacitive technology is also progressing, especially those based on charge transfer sensing methods, which will bring great changes to the way that electronic and electrical product designers implement touch screens. .
