The working principle of LED matrix display
First, we need to understand the three important parts that make up the matrix LED display, they are the matrix board, anode and cathode.
The role of the matrix board is responsible for the complex circuit signals into a content that people can read, while the anode and cathode is responsible for controlling the matrix board rows and columns of the output.
Since the signal transmission of the matrix board is from the anode to the cathode, the anode needs to go through the cathode first to parse the signal after receiving the signal from the LEDs, and finally display which LEDs should be turned on or off on the matrix board.
It is worth mentioning that LED dot matrix can display single color, double color or full color depending on the LED beads.
Advantages of LED matrix display
Thanks to the powerful content updating function of dot-matrix LED display, we can choose the appropriate text content for display according to the actual scene. We also support the setting of color, font and other parameters for the text content.
As LED matrix display is composed of LEDs. As we all know, LED can emit light on its own without the help of backlight, so its energy saving effect is very excellent. The energy-saving advantage of matrix LED display is not only more environmentally friendly, but also saves us more money.
Like other LED displays, matrix LED display also supports customization according to size, shape or other parameters. No matter, you have any idea, you can put forward. We will reproduce it perfectly for you.
LED matrix displays are made up of one single LED with high brightness. In this way, even if it is used outdoors in strong sunlight, it will not affect the reading of the text. Moreover, the high brightness is more likely to attract people’s attention, so LED dot matrix is usually used for traffic instructions or store promotional information display.
When to use LED matrix display?
Compared with other conventional types of LED displays, LED matrix displays contain more pixels, so they can display more detailed images. This means that we can see a clearer and more perfect image when we are viewing from a close distance. On the flip side, if one is too far away, then the image may not be seen in as much detail.
General LED matrix display is usually used to display text on the top of the store or display video at home, the display area is not more than 10 square meters. It is mainly used to replace video walls, TVs or static LED display panels.
Since the area of matrix LED display is not very large, then its cost is naturally lower than other large area LED display price. In addition, the smaller area of matrix LED display, the cost of maintenance is also much smaller.
As the use of matrix LED display for photography and video requirements are not high, so the default use of the conventional refresh rate. If there is no special requirement for refresh rate, then LED matrix display has the best cost performance.
