In this era of internet information, LCD screens are ubiquitous and widely used. Everyone will have some understanding of LCD screens to a greater or lesser extent. Today, the manufacturer of high brightness displays will introduce the classification of LCD screens, which can be roughly divided into the following types: TN-LCD and STN-LCD, HTN-LCD, FSTN-LCD, TFT-LCD. And each type also has different characteristics, mainly depending on what type of terminal product it is applied to.
TN-LCD is a twisted nematic LCD display screen. The electronic watches, calculators, game consoles, and other LCDs we usually see are mostly TN-LCD.
STN-LCD is the abbreviation for Super Twist Liquid Crystal Display. Namely, super twisted nematic LCD It has a similar structure to TN-LCD, but its twist angle is not 90 degrees, but between 180 and 270. Although only the twist angle is different, its working principle is completely different from TN-LCD. STN-LCD is currently a mid-range product in LCD production. It has the characteristics of displaying more information than TN-LCD, and is mainly used for various instruments, notebooks, laptops, etc.
HTN-LCD is the abbreviation for High Twist Neural Liquid Crystal Display. The high distortion nematic LCD display screen, HTN-LCD, has a distortion angle between 100 and 120 degrees, which is between TN-LCD and STN-LCD. At present, there are not many HTN-LCDs, and their performance is also between TN-LCD and STN-LCD.
FSTN-LCD is the abbreviation for Film Super Twist Neural Liquid Crystal Display. Here, Film refers to compensation film or delay film, so FSTN-LCD is called compensation film ultra twisted nematic LCD display screen. By using a specially treated compensation film, the shortcomings of STN-LCD can be overcome. TFT-LCD, also known as active matrix LCD with thin film transistors, is currently the highest grade product in the LCD screen market. It is mainly used for laptops, LCD color TVs, etc. The manufacturing process of TFT-LCD is relatively complex and the price is relatively high.
