Descriptions:
A Segment LCD display (or Segmented LCD) is a type of LCD (Liquid Crystal Display) that uses a series of segments to form numbers, letters, or other characters.
How it Works:
The display consists of several segments (typically 7 or 14), arranged in a pattern to form individual digits or characters.
Each segment is an individual part of the display that can either be turned on or off to create different patterns, such as numbers, letters, or symbols.
Key Features:
1. Low Power Consumption
2. Simple Characters
3. Backlighting (optional)
4. High Visibility

Notices: The differences between TN, HTN, STN, FSTN, and VA LCD types?
TN (Twisted Nematic) LCD screens, the twisted orientation of the liquid crystal molecules is deflected by 90°. The display content is relatively simple, and the main features are relatively black fonts, high contrast, low power consumption, and driving voltage, but a small viewing angle. Common applications are clock products, calculators, etc.
HTN (High Twisted Nematic) LCD screens, nematic liquid crystal molecules are sandwiched between two transparent glasses, and the orientation of the liquid crystal molecules is deflected 100~140 degrees between the two layers of glass. The main features are similar to TN, but the viewing angle is wider than TN. Common applications are indoor furniture, medical equipment, etc.
STN (Super Twisted Nematic) LCD screens, the liquid crystal rotates 180~270 degrees in the LCD screen, the viewing angle is better, and there are generally gray films, yellow-green films, and blue films. Widely used in high-channel COB/COG, such as communication devices, etc.
FSTN (Film+STN) LCD screen, to improve the background color problem of ordinary STN, a compensation film is added to the polarizer to eliminate dispersion and achieve black and white display. Common applications are industrial instruments, etc.
VA (Vertical Alignment) LCD screens, black background, and color patterns, high contrast, can achieve a multi-color silk screen display effect, and have certain requirements for driving voltage. It is mostly used for segment COB and low-channel drive products.
Segment LCD Applications:
1. Medical Equipment
2. Industrial and Commercial Use
3. Clocks and Watches
4. Smart Home Devices
5. Appliances
