Solution to electromagnetic interference problem of projection capacitor touch screenDeveloping mobile handheld devices with touch screen human-machine interfaces is a complex design challenge, especially for projection capacitive touch screen design, which represents the mainstream technology of current multi touch interfaces. The projection capacitive touch screen can accurately locate the position of fingers lightly touching the screen, and it distinguishes finger position by measuring small changes in capacitance. A key design issue to consider in such touch screen applications is the impact of electromagnetic interference (EMI) on system performance. The performance degradation caused by interference may have adverse effects on touch screen design. This article will explore and analyze these sources of interference. Projection type electricity
