The latest main feature of bar screens is remote control encryption control terminals. One mobile phone, tablet, or computer can control all terminals through the corresponding information dissemination system. No matter where you are, compared to traditional LCD screens, LCD bars can be customized according to the size of the shelves. It can be perfectly integrated with the shelves without occupying the display space of the original product. It has the characteristics of high clarity, high luminous efficiency, and high color saturation, and can provide different brightness products according to the usage environment.

2、 The main research purposes of strip screen characteristics are:

1. Relatively high temperature T: It is necessary to ensure that the development of the entire social system is in a nematic phase within the required temperature change range, and there should be no crystallization phenomenon or other phase states, such as near crystal equality;

2. Dielectric coefficient Δ ε: Adjust the size of Δ ε to meet the requirements of enterprise user management for a threshold voltage;

3. Optical anisotropy δ n: Adjust the size of δ n to meet the user's requirements for different box thicknesses;

4. Pitch p: an important parameter that determines the thickness of the box and the amount of chiral agent added.

3、 Precautions for using bar screens

1. The influence of ultraviolet light

Disrupting the c-c bond, causing the polymer's c-chain to break, affecting the aforementioned properties;

2. The impact of containers

We are using hard glass, a type of glass with high silicon and boron content. Ordinary glass bottles are made of sodium glass, and the electrical resistivity of liquid crystals stored in glass containers will decrease.

The conditions for storing the LCD of a strip screen are: sealing, avoiding light, drying, and room temperature.

3. Environmental impact

A small amount of conductive material is sufficient to reduce the resistivity, as the liquid crystal resistivity is between 1011-1012 Ω/cm2,

4. The influence of temperature

Liquid crystals are less sensitive to temperature than to ultraviolet radiation. When using LCD, the heating time should be minimized as much as possible.
