21 inch touch screen all in one pc.At present , the competition pattern of various touch screen technologies is: resistance and capacitance dominate in the small and medium size field, and various technologies coexist in the large size field. However, from the long-term development trend, due to the inherent shortcomings in the service life and light transmittance of the resistive touch screen, it is inevitable that it will be replaced by other technologies in the future. The performance and quality of the projected capacitor are significantly better than that of the resistive type. At present, the technology is relatively mature. More importantly, there is still room for technical improvement, and the cost reduction space is also large. It may even be lower than the resistive type. Therefore, capacitive touch screens will dominate the development of touch screens in the future.
