Due to the fact that LCD is made up of two thin liquid crystal glasses that are sealed together with sealant. Because of this, it is strictly forbidden to fall on the LCD surface while using it, or to hit or squeeze it with hard objects, or to apply uneven assembly force, in order to avoid damaging the display.

When using liquid crystal products with metal pins, it is essential to avoid pulling or twisting of the metal pins during use. When soldering pins with a soldering iron, the soldering time should be kept to a minimum (less than 34S) to avoid damaging the reliable connection between the metal pins and the LCD and rendering the TFT display inoperative.

As a plastic polarizer, the LCD surface should be protected during use from being scratched or contaminated by hard objects. After completing the assembly, peel away the protective film from the polarizer's viewing surface on the LCD.

In addition, because LCD is a lower voltage, lower power product, if the glass surface is damp and conductive, it will produce a crosstalk display, which will cause the TFT display  to be unusable.

The driving voltage must have as small a DC component (50mV) as possible in order to prevent the electrochemical reaction of liquid crystal from affecting the life of the LCD. (5)

In light of the fact that both liquid crystal and polarizer are organic substances, it is important to avoid exposing them to ultraviolet rays for an extended period of time while in use, as this can cause a photochemical reaction and deterioration of LCD performance.

A specific angle is created by the liquid crystal molecules in MVA, which results in an extremely fast response time for the device. A number of different display technologies are currently in widespread use in the mainstream market, including TN, IPS, and MVA.
