The Threat of Static Electricity to LCD Monitors
We have received inquiries from some customers regarding the above issues, and have summarized them below:
The answer to the above questions is affirmative: it absolutely has an impact!
Here's an explanation of the hazards and protections against static electricity to electronic components:
Hazards:
① Static electricity attracts dust, altering the impedance between circuits, affecting product function and lifespan.
② Electric fields or currents can damage the insulation or conductors of components, rendering them inoperable (completely destroyed).
③ Heat generated by instantaneous electric fields or currents can damage components, allowing them to continue functioning, but shortening their lifespan.
Protection:
1. Static electricity protection at the work site. Static-sensitive devices should be handled in anti-static work areas.
2. Static electricity protection for personnel. Operators should wear anti-static work clothes, gloves, anti-static work shoes, anti-static caps, wrist straps, and heel straps.
3. Static electricity protection during storage and transportation. Static-sensitive devices must not be stored or transported while under a charged state.
To achieve the above functions, the basic approach is to reduce the voltage of charged objects to within the design-required safe value. This requires that the charge (Q) and resistance (R) in the following formula be small, and the electrostatic capacitance (C) be large.
