Common types of LCD screens include the following:
TN LCD screen: Twisted nematic panel is the most widely used entry-level LCD panel with low production cost and is widely used in mid- to low-end LCD products on the market. Its viewing angle is relatively poor and its light transmittance is low, resulting in a relatively dark picture effect, but it is small in size, light in weight and cheap in price.
HTN LCD screen: Highly twisted nematic, nematic liquid crystal molecules are sandwiched between two transparent glasses, and the orientation of the liquid crystal molecules is deflected by 110 to 130 degrees between the two layers of glass.
STN-LCD: super twisted nematic liquid crystal display, which displays by changing the electric field through an external electric field. The liquid crystal of the STN LCD screen rotates 180~270 degrees in the LCD screen, and due to dispersion, the background color of the LCD screen will display a certain color, such as yellow-green or blue.
FSTN LCD screen: In order to improve the background color problem of ordinary STN, FSTN adds a compensation film to the polarizer to eliminate dispersion and achieve black and white display.
TFT LCD screen: Thin film transistor type LCD screen, also known as "true color" display screen. TFT is the prototype of all current LCD screen improvements, focusing on pixels and color balance, and different color qualities have different display effects. It belongs to the dot matrix type and is widely used in mobile phones, computers and other mobile devices.
Segment code LCD screen: The initial product was developed in Japan. It is mainly used to replace LED digital display tubes, such as calculators, clocks, etc. The displayed content is all numbers.
Dot matrix screen: It is divided into LCD dot matrix screen and LED dot matrix screen. It is composed of many fixed-size dots and arranged in an array. These dots form pixels to display images.
LED screen: A display screen composed of many LED lights, commonly seen on streets and billboards.
OLED LCD screen: displays images based on the self-illumination of pixels, providing more possibilities for modern display technology.
Each of these LCD display types has its own characteristics and application areas, and the selection needs to be considered based on specific needs.
