— What exactly is a monochrome LCD screen? What are its characteristics and advantages?
Monochrome LCD screen, also commonly known as black and white screen. It gets its name because it can only display a single color. It can be made into white characters on a black background, white characters on a blue background, black characters on a yellow background, black characters on a yellow-green background and so on. After technological development and corrections, Hangzhou Jingxian has been able to make color segment code LCD screens. The biggest advantage of the monochrome LCD screen is that the user design is relatively simple, and the main control I/O port is less.
Second, how to classify monochrome LCD screens and what are their characteristics?
A. There are many classifications of monochrome LCD screens, as follows:
1. Classification based on the content displayed: segment code LCD screen, graphic dot matrix LCD screen (with and without Chinese character library respectively), character LCD screen 2. Classification from the process: segment code LCD screen, COB LCD screen, COG LCD screen, TAB LCD screen
3. Classification from the background of its display: yellow-green LCD screen, blue film LCD screen, gray film LCD screen
4. Classified from the materials used are: VA (BTN), TN, HTN, STN, FSTN. All materials for segment LCD screens are possible to use. Dot-matrix LCD screens use STN a bit more, while others are relatively less used.
5. In addition to the Chinese font library with and without Chinese font library, dot matrix screens can also be distinguished by dot matrix, such as: 12232, 12832, 12864, 19264, 160128, 160160, 24064, 240128, 320240, etc. , We most often use 12232, 12864, 24064, 320240.
6. It is also distinguished from the working temperature, which is divided into normal temperature (-20~70 degrees), wide temperature (below -20 or higher than 70 degrees), from the perspective of classification, 6-point viewing angle, 12-point viewing angle, That is to say, look at the display screen from the 6 o'clock or 12 o'clock direction of the clock.
