Under the condition of rapid development, LED screens are more and more widely used. In LED display, the most important thing is LED lamp. The quality of the LED lamp affects the quality of the LED display. And it’s the most used key component in the whole screen. It’s also the main thing that determines the optical display performance of the entire screen, which directly affects the audience’s evaluation of the screen.
What effect does LED lamp have on LED display?
1. Viewing angle
The viewing angle of the LED display is determined by the viewing angle of the led lamps. At present, the viewing angle of the display is mostly 120° horizontal and 60° vertical. Some high-rise displays have higher requirements for vertical viewing angle. Viewing angle and brightness contradict each other, and a large viewing angle will inevitably reduce brightness. The choice of perspective needs to be determined according to the specific purpose.
2. Brightness
The brightness of the LED lamp is an important determinant of the brightness of the screen. The higher the brightness of the LED lamp, the greater the margin for the use of current of the screen, which is good for saving power consumption and maintaining the stability of the LED lamp. LED lamps have different angle values. When the chip brightness is fixed, the smaller the angle, the higher the brightness, but the viewing angle of the screen is smaller. For LED displays with different dot pitches and different viewing distances, a balance should be found in brightness, angle, and price.
3. Antistatic ability
LED is a semiconductor device, which is sensitive to static electricity and can easily cause static failure. Therefore, the anti-static ability is very important to the lifespan of the LED display. Generally speaking, the failure voltage of the human body electrostatic mode test of the LED lamp should not be lower than 2000V.
4. Lifespan
The theoretical lifespan of the LED lamp is 100,000 hours, which is much longer than the working lifespan of other parts of the LED display. Therefore, as long as the quality of the LED lamp is guaranteed, the working current is appropriate, the PCB heat dissipation design is reasonable, and the LED screen production process is rigorous, the LED lamp will be one of the most durable parts in the LED display.
5. Consistency
The full-color display is composed of countless red, green and blue LEDs. The brightness and wavelength consistency of each color LED determines the brightness consistency, white balance consistency and chromaticity of the entire display. Normally, LED display manufacturers require suppliers to provide LEDs with a wavelength range of 5nm and a brightness range of 1:1.3. These indicators can be achieved by the supplier through the classification of the color separation machine. Voltage consistency is generally not required.
LED display lamp beads can be separated from DIP and SMD; the main difference is the brightness, pixel density, and durability.
What is the difference between DIP and SMD?
The lamp beads can account for 60% of LED screen prices, so it has a big price gap from the different LED display manufacturers by the same size and pixel pitch.
The same brand of the lamp is also divided into gold wire, copper wire, large chip, and channel version chip; you need to confirm the specific model when choosing the brand.
Next, we will introduce in detail LED lamp beads suppliers and include their Website.

Conclusion
Choose good lamp beads, can make the LED display longer life and good effect. When we don’t know how to choose a lamp bead brand, we can recommend as below.
Outdoor fixed LED screen, high brightness lamp beads, Nationstar, if the price is acceptable, we recommend using DIP LED.
Indoor advertising LED screen, you can choose Kinglight or Nationstar; you need to use an indoor black LED, ensuring good contrast.
LED display lamp beads are the most important materials that make up the LED display; Not only to identify the good and bad lamp bead brands, more need to choose a good LED display manufacturers to help you produce the LED display.
