If it's just a standalone LCD display, the public has a certain level of understanding of it, but if a limitation is added in front of it, it's like a dot matrix LCD display. At this point, people may wonder what a dot matrix LCD is? In fact, this thing should be very common for drivers of vehicles, because the screen in front of the steering wheel that displays the fuel level and speed is a dot matrix LCD or similar display screen when we are driving a car.
The LCD array is displayed line by line in the order of the display code. The display time for each line is about four milliseconds, and due to the human visual transient phenomenon, eight LCD lines are displayed simultaneously. If the display time is too short and the brightness is not enough. If the display time is too long, there will be a flickering sensation. The low voltage scanning method used can output display signals at high levels, that is, sequentially outputting low levels to the line signals. At any time, only one line will be in a lit state while the other lines are in a closed state.
In fact, in the past, LCD screens could only be used for simple display of fixed characters, patterns, and numbers. However, various patterns can also be displayed through programming to make the picture vivid and realistic, but it may not meet the requirements for displaying multiple Chinese characters; However, dot matrix LCD can not only display all letters in English, but also any numbers, graphics, curves, and Chinese characters, which are very special. At the same time, it can also achieve dynamic display functions such as font scrolling and flashing, adding more fun. However, sometimes the displayed content may be more rigid, and each has its own advantages.
Before innovation, dot matrix LCD displays were relatively single, which also meant that their range of applications was not as wide as other competitors, and this also created their market value, which was not as high as other widely used LCD screens. But after improvement and development, its scope of use has undergone tremendous changes, and due to the convenience brought by its manufacturing cost, more and more businesses are willing to choose it. Therefore, the commercial value brought by innovation and progress is unlimited.
