Dot matrix LCD screen It is a screen composed of many dots. This is a distance array screen arranged horizontally and vertically. It consists of many points. For example, the 12864 dot matrix LCD screen is a typical representative dot matrix LCD screen in our daily work and life.
Dot matrix LCD screens are mainly used in places with obvious screen brightness, such as bus stop signs, billboards at offline gates, welcome signs at the entrance of companies, signs for events, etc. These occasions need to be applied to dot matrix in these places. LCD screen.
For a 12864 screen, there are 128 points in the horizontal column and 64 points under the vertical column. There is an LED light behind each point. Behind these lights is a main control board. We can input the program into the main control board, and through this single-chip chip, you can display the text content you want to display at will.
Dot matrix LCD screen Main display functions:
Because the dot matrix LCD screen is composed of many LED light-emitting diodes, such as the light emitted by this LED, its brightness is very high. When these LED lights are powered up, they will emit a lot of light and show a certain density on these screens. This kind of LED has a relatively long service life and can also change various colors according to individual needs, which has great advantages in display brightness.
Two: Continue to the LCD screen
After introducing the dot matrix screen above, we next introduce its LCD screen to display some functions.
LCD liquid crystal screen It cannot perform self-illumination, so it needs a backlight module to emit light. The backlight module is a board composed of some LED light boards. As long as we power up these light-emitting panels, it will emit light to the backlight.
Now? LCD liquid crystal display technology is also very mature. There are many industrial equipment and some electronic products. It needs to use this LCD screen, because the purchase cost of high-end LCD screen is relatively high, so the a-gauge high-end LCD screen on the market needs to be purchased as needed.
The LCD liquid crystal screen display mainly has the following characteristics:
1. Better eye protection
Like some ebooks, they are also used LCD screen instead of OLED screen because it is more eye friendly because readers who use ebooks need to watch the screen for a long time. To better protect our eyes, they will use it LCD screen better.
2. High pixel density
Compared to some other screens, this LCD screen has a higher density.
3. Longer service life
Because the LCD screen is not made of organic materials, it is made of inorganic materials, so it will not age too fast and can be used for a longer time.
