What Are The Effects Of Infrared LED Beads On LED Display Screens?

Five Effects of Infrared LED Beads on LED Display Screen
1. Perspective
The viewing angle of an LED display screen is determined by the viewing angle of the infrared LED beads. Currently, most outdoor display screens use a horizontal viewing angle of 100 ° Vertical viewing angle of 50 °; The elliptical LED is used, and the indoor display screen adopts a horizontal and vertical angle of 120 °; Surface mounted LED. The display screen on the highway is generally selected at a 30 ° angle due to its particularity; A circular LED with a viewing angle is sufficient. Some display screens on high-rise buildings require a high vertical viewing angle. Perspective and brightness are contradictory to each other, and a large perspective will inevitably reduce brightness. The choice of perspective needs to be determined based on the specific purpose.
2. Brightness
LED brightness is an important determinant of display screen brightness. The higher the brightness of the LED, the greater the margin of current usage, which is beneficial for saving power consumption and maintaining LED stability. LEDs have different angle values. With a fixed chip brightness, the smaller the angle, the brighter the LED, but the smaller the viewing angle of the display screen. Generally, a 100 degree LED should be selected to ensure sufficient viewing angle for the display screen. A balance should be found between brightness, angle, and price for display screens with different point spacing and line of sight.
3. Inefficiency
Due to the fact that full-color display screens are composed of tens of thousands or even hundreds of thousands of pixel points composed of red, green, and blue LEDs, the failure of any color LED will affect the overall visual effect of the display screen. Generally speaking, according to industry experience, the failure rate of LED display screens from assembly to aging for 72 hours before shipment should not exceed 0.03% (referring to failures caused by the infrared LED beads themselves).
4. Anti static ability
LED is a semiconductor device that is sensitive to static electricity and easily leads to electrostatic failure. Therefore, the anti-static ability is crucial for the lifespan of the display screen. Generally speaking, the failure voltage of the human body electrostatic mode test for LED should not be lower than 2000V.
5. Lifespan
The theoretical lifespan of LED devices is 100000 hours, which is much longer than the working lifespan of other components in LED displays. Therefore, as long as the quality of LED devices is guaranteed, the working current is appropriate, the PCB heat dissipation design is reasonable, and the production process of the display screen is rigorous, LED devices will be one of the most durable components in the entire display screen.
LED devices account for 70% of the price of LED displays, so LED devices can determine the quality of LED displays. China is both a major producer of LED devices and a gathering place for the production of LED display screens. The high-tech requirements of LED display screens are the future development trend, and the high-quality requirements of LED display screens are not only related to the direction of LED display screen manufacturers, but also to the development of LED display device manufacturers. From the control of LED devices, promote China's transformation from a major LED display manufacturing country to a strong LED display manufacturing country.
