LCD Touch screen For iPhone XR

                                                How to solve the electromagnetic interference problem of the touch screen Developing mobile handheld devices with touchscreen HMIs is a complex design challenge, especially for projected capacitive touchscreen designs, which represent the current mainstream technology for multi-touch interfaces. The projected capacitive touch screen can accurately locate the position where the finger touches the screen, and it can judge the position of the finger by measuring the small change of capacitance. A key design consideration in such touchscreen applications is the effect of electromagnetic interference (EMI) on system performance. Performance degradation caused by interference can have a detrimental effect on touch screen designs, and these sources of interference will be explored and analyzed in this article. Proje…
