In modern display technology, LED lamp beads play an important role in many areas with their unique advantages. From light lighting to traffic instructions, from computer display to billboards, the application of LED lamp beads is everywhere. This article will explore the importance of LED lamp beads on the large LED electronic screen, as well as how to identify its advantages and disadvantages.
Wide application of LED lamp beads
LED lamp beads, that is, light -emitting diode, is a semiconductor luminous device, is widely used in various production areas with its efficient, energy saving and environmental protection characteristics. In the field of LED electronic screens, LED lamp beads are not only the basic units that constitute the display, but also a key factor that determines the performance of the display. Take you to understand the working principle of LED lamp beads.
The key role of LED lamp beads in LED electronic large screens
Number of: In the full color screen of LED, thousands of LED lamp beads may be used per square meter, which is the key device used in the entire machine.
Decisive factor of optical properties: LED lamp beads directly affect the optical display performance of the display screen, thereby affecting the audience's evaluation of the display.
The proportion of cost: LED lamp beads accounted for a large proportion of the overall cost of the LED electronic display, ranging from 30%to 70%. There are 3 LED lamp beads.
How to identify the advantages and disadvantages of LED lamp beads
Methods to identify the advantages and disadvantages of LED electronic display lamp beads include:
Watering joint inspection: The LED lamp beads produced by regular manufacturers use SMT patch process, and the solder joints should be flat and flawless.
FPC quality: FPC (flexible circuit board) is divided into two types: copper -applying and pressing copper. The copper foil with copper plates is raised and can be observed at the connection with the FPC by pad pad.
Surface cleanliness: LED lamp beads produced by SMT process are well cleaned on the surface, without obvious impurities and stains.
Chip and production process: The LED is tested through aging equipment and testing equipment. Compared with the brightness attenuation of different manufacturers LED, the minimum attenuation is the best quality. Take you to understand LED chips: technology, application and development.
The importance of LED lamp beads to LED electronic screen
Perspective: The perspective of LED electronic screen depends on the perspective of LED lamp beads. Different application scenarios have different requirements for perspective.
Brightness: LED brightness is the decisive factor of the brightness of the electronic display screen. The higher the brightness, the larger the current margin, which will help save power consumption and maintain LED stability. This is about Nit's brightness.
Lise efficiency: The full -color electronic display consists of a large amount of red, green, and blue LEDs. Any color LED failure will affect the overall visual effect.
Anti -electrostatic capacity: LED semiconductor devices are sensitive to static electricity, and anti -static capabilities are essential to the service life of the display.
Life: The theoretical life of LED lamp beads is 100,000 hours, which is one of the most durable components in the display.
in conclusion
LED lamp beads occupy a pivotal position in the LED electronic display, and the quality directly determines the performance and life of the display. With the continuous improvement of LED electronic display technology, the requirements for LED lamp beads are getting higher and higher.
