There are five types of LCD liquid crystal display: TN, HTN, VA, STN&FSTN (DFSTN);
The difference between them is: the viewing angle is an increasing relationship, that is, the viewing angle of HTN is wider than that of TN, STN is wider than HTN, the viewing angle of TN is 60 to 90 degrees, and the viewing angle of HTN is 90 to 120 degrees. , The viewing angle of STN&FSTN (DFSTN) is 120~180 degrees;
The cost is also increasing, so choose the type of LCD screen product according to the needs of the customer's product;
TN and HTN are generally used for products with low value and low requirements. The common display modes include positive display reflection, positive display full transparency, positive display semi-transmission, negative display full transparency, and white characters on a blue background;
The common modes of STN are positive display yellow-green mode (yellow-green background, display font is darker blue), gray mode (gray background, display font is darker blue), negative display blue mode (blue background, display white characters);
FSTN belongs to the black and white series of STN products, that is, the FSTN display mode only has black characters on white background and white characters on black background. The substrate part also belongs to the STN type. Common display modes include black characters on reflective white background, and black on white background. Black text on a translucent white background and white text on a fully transparent black background. The white text on a fully transparent black background can only be guaranteed by a dual-compensation polarizer to ensure its darker background. It is called DFSTN in the industry, such as ordinary FSTN negative. Significant (that is, do not use dual-compensation polarizer, the background color will be more transparent, bluish, usually not achieve the desired effect of the customer);
Finally, I will introduce VA products. The predecessor of VA products is TN black film products. The earliest TN black film products use TN substrates. All the parts of the product that do not need to be displayed are screen-printed with black ink to achieve the background color opaque. As a result, this product is mostly used in automotive products. In recent years, this technology has been eliminated. By citing advanced technology, and using imported substrates, PI liquid & liquid crystals, we have developed a kind of color that can be done without screen printing ink. Products that are opaque, such products are VA products, and VA products have only one display mode, that is, white text on a black background;
The VA LCD screen is most commonly used to compare with the third smallest TN product. In fact, it is not comparable. The third smallest TN product is just a darker background color on the basis of the TN negative display product. Still transparent
