Abstract

Abstract

The display is an important part of human-computer interaction. When the human body electrostatic discharge occurs on the surface of the display, it may lead to hardware and software faults. In order to study the experimental characteristics of air electrostatic discharge on display, the air electrostatic discharge current and the displacement current through the display screen were measured by a self-made device. It is found that the peak value of discharge current increases with the increase of approaching velocity, and the rising time decreases with the increase of approaching velocity. In the voltage range of ±10-±12 kV, the rise time increases and the peak current decreases under the influence of arc length. With the increase of the distance between the measurement point and the discharge point, the peak value of the displacement current waveform decreases and the rising time increases. The peak value of the positive polarity discharge is larger and the diffusion range is wider, while the rising time of the negative polarity discharge is more obvious. The charge density can be calculated from the displacement current waveform and its distribution. The charge density decreases with the distance of discharge position increasing. Although the peak value of negative polarity discharge current is lower than that of positive polarity, the charge density is higher.This indicates that the negative polarity discharge has a higher damage risk.
