Explanation:

A liquid crystal screen works by the polarization of the molecules that make up the screen by a local electric field, to abalone there must be a light source in the traces pattern in such a way that when a part of the screen is polarized the light manages to come out and we see the image. The polarization of the liquid crystal is a very fast process, therefore Technician A's comment is incorrect.

Liquid crystal displays (LCDs) are generally small and excessive pressure can break the glass and damage the display.

From the previous clarifications, technician B is right
