Analysis of the difference between OPP tape and BOPP tape

PP is a raw material for a polypropylene transparent tape substrate, and O is a directionally stretched polypropylene. O mainly refers to the transparent tape with high tear strength in the production process of transparent tape. In fact, the transparent sealing adhesive is basically OPP tape . Let's take a look at the difference between OPP tape and BOPP tape, as follows:


Analysis of the difference between OPP tape and BOPP tape
1. OPP is a uniaxially stretched polypropylene, and the English full name is Oriented Polypropylene. OPP tape: Scotch tape based on polypropylene film, with high tensile strength, light weight, non-toxic and tasteless, environmentally friendly, its performance is good, and its use range is also very wide.

2, BOPP is biaxially oriented polypropylene, the English full name is Biaxial Oriented Polypropylene, that is, the double-line stretching in the longitudinal and transverse directions, so that its performance is greatly improved. Its characteristics: thin thickness, transparent appearance, non-toxic, odorless, good safety, easy to use, high efficiency, high anti-buffering strength, good retraction rate.

There are many kinds of LCD classification standards, which can be divided into passive matrix and active matrix according to the driving mode

Passive matrix: Passive matrix LCD can be divided into TN-LCD(TwistedNematic LCD), STN-LCD(SuperTN-LCD) and DSTN-LCD(Doublelayer STN-LCD).


Active matrix: Active matrix LCD, also known as TFT-LCD, is widely used at present. Tft-lcd is short for thin-filmliquid-Crystal Display

The TFT-thin Film Transistor

Liquid Crystal Display

Short for TFT-LCD Liquid-CrystalDisplay

Tft-lcd has been widely used in various display equipment due to its advantages of small size, light weight, low radiation, low power consumption and full color.


Functions of TFT-LCD structure

(1) Backlight plate module: provide the source of light;

(2) Upper and lower polarizing plates, TFT Glass Substrate, liquid crystal: forming polarized light, controlling the passage of light;

(3) Color filters: Provide Tft Lcd red, green and blue (three primary colors of light) sources;

(4) ITO transparent conductive layer: provide transparent conductive path;

(5) Photo Spacer: Provide a fixed height for color filters and TFT Glass Substrate. As a space for liquid crystal infusion, and as a support for the upper and lower Glass layers.
