Abstract

This paper is centered on the phenomenological description of spark-less discharges to displays. It analyzes the conduction currents injected onto the glass and the displacement currents flowing through the glass for spark-less discharges to metal-backed glass such as an liquid crystal display (LCD). Further, it provides a full-wave simulation model to reproduce the displacement current flowing through the glass into the display's inner electronic structures. The currents can reach 10 A having pulse widths of tens of nanoseconds. Discharge voltage levels, polarities, approach speed, and humidity influences were investigated. Lichtenberg's dust figure method was used to help visualize the charge distribution and residual charges after surface discharging.
