Hi

An LCD screen, which is not a touchscreen and does not have a driver circuit, does it still require ESD protection ? This was picked up in an audit and the auditor feels ESD protection , including packaging, is required.

However, reaching out to the supplier of the LCD screen , they have stated the following - The display pattern of the segmented display is solidified on the glass substrate through a film mold. It can only control the on/off segment and cannot dynamically change the content. The design itself does not rely on sensitive sensors but it needs to be driven by AC voltage through COM/SEG pin. If DC voltage is mistakenly applied mistakenly, it will cause permenant damage.

Any thoughts or feedback would be appreciated

 

Sounds like an AI response.

Yes, LCD screens need electrostatic protection.
