The LCD array displays the codes line by line in the order in which they are displayed. The display time of each line is about four milliseconds. Due to the transient phenomenon of human vision, 8 LCD lines will be displayed at the same time. If the display time is too short, the brightness is not enough. If the display time is too long, there will be a flickering feeling. The low-power scanning method it adopts can output high-level display signals, that is, it outputs low-level line signals in sequence. Only one line can be lit at any time, and other lines are closed.
In fact, in the past, LCD screens could only be used for simple display of fixed characters, patterns, and numbers. However, they could also be programmed to display various patterns to make the screen design vivid and lifelike, but they were not necessarily able to meet the needs of displaying a variety of Chinese characters requirements and the dot matrix LCD display can not only display all letters in English, but also display any numbers, graphics or curves, and Chinese characters. These are very special. It can also realize dynamic display functions such as font scrolling and flashing. It is more interesting, but sometimes the display content is more rigid, so each has its own merits.
Before innovation, the dot matrix LCD screen was relatively simple, which meant that its usable range was not as large as other competitors. This also contributed to its market value, which was not as high as other widely used LCD screens. . However, after improvement and development, its scope of use has changed greatly. Because of the convenience brought by its manufacturing cost, more and more businesses are willing to choose it, so the commercial value brought by innovation and progress is endless.
