1. Display effect:
Because LED is basically a current-sensitive device, its forward voltage drop dispersion is very large, and it is also related to temperature. In order to ensure that the digital tube has good brightness uniformity, it needs to have a constant working current, and cannot be affected by temperature and other factors. In addition, when the temperature changes, the driver chip can automatically adjust the output current to achieve color balance temperature compensation.
2. Safety:
Even a short time of current overload may cause permanent damage to the LED. Using constant current drive circuit can prevent large area damage caused by current fault.

What is the composition of LED dot matrix Chinese characters? Let's get to know
The indoor full-color LED display screen has the information release function, which can select a variety of styles, flexibly control the font size, and rich playback methods.
How to disinfect without damaging the display screen? Let's understand together.
Nowadays, people often see full-color large-screen advertisements or videos in public places such as hospitals, subways, schools, and even some wedding scenes.
Dot matrix LED display is suitable for indoor text and simple picture playing. What are the advantages?
The principle of LED dot-matrix screen is to take a simple 8X8 dot-matrix as an example. It is composed of 64 light-emitting diodes, and each light-emitting diode is placed at the intersection of row line and column line. When a corresponding row is set a
LED dot matrix screen is composed of LED (light emitting diode). It displays text, pictures, animations, videos, etc. by turning on and off the light beads. It is a modular display device composed of all components, usually composed of display module, con
The high-definition LED display screen is becoming more and more popular. Let me introduce the problem of improving the definition of electronic display screen.
The quality of a full-color LED display can be identified from the following aspects:
In recent years, the use frequency of indoor LED display screen is also increasing gradually, and the use is also more extensive. But there is a problem that users are very concerned about, that is, how to extend the service life of indoor LED display scr
According to the different LED nixie drive mode, can be divided into static and dynamic two categories.
Most conference rooms now use large-screen displays, and most customers will have a high degree of integration of large-screen definition or display effect, so they will definitely not use projectors and LCD splicing screen equipment, and the application
In the city streets, shopping malls often can see its figure, so, when buying full color LED display should pay attention to what?
As with traditional electronics, the large screen of LED display requires not only attention to the method, but also maintenance of the display to make the LED display's screen last longer.
