In recent years, [LED displays](https://sostron.com/product?category=2) have been widely used in fields such as indication, display, decoration, backlight, general lighting and urban night scenes. There are many types of LED displays, including LED indoor engineering screens, LED outdoor engineering screens, LED commercial advertising screens, LED creative screens, LED stadium screens, [LED floor tile screens](https://sostron.com/product/series/52599/index?category=2), LED color screens, etc.  

In the complicated LED display industry, different companies adopt different sales strategies. Some companies focus on price competition, but often do not perform well in terms of materials, performance and quality. Therefore, consumers need to pay attention when choosing LED displays and not be greedy for cheap, so as not to buy low-quality defective products.

Key performance of LED devices: The most critical component of LED display screen is LED device. When selecting LED devices, pay attention to performance indicators such as high brightness, low operating voltage, low power consumption, large size, long life, impact resistance and stable performance.

Failure rate: When examining the failure rate of an LED display from assembly to shipment, it is required to be no higher than 3/10,000. This is a failure caused by the LED device itself.

Anti-static ability: Since LED is a semiconductor device and is sensitive to static electricity, anti-static ability is crucial to the life of the display screen. The human body electrostatic mode test failure voltage of LEDs should not be lower than 2000V.

Flatness: The flatness of the LED display surface should be within 0≤a≤1mm to ensure that the displayed image is not distorted. Local bulges or recesses can cause blind spots in the viewing angle of the display.

Brightness and viewing angle: The brightness of the indoor full-color LED display should be above 800cd/m2, and the brightness of the outdoor full-color LED display should be above 1500cd/m2. The size of the viewing angle directly determines the viewing area of the LED display, and the LED chip has an important impact on brightness and viewing angle.

White balance effect: The white balance effect is one of the most important indicators of the LED display. The LED chip is required to display pure white when the ratio of the three primary colors of red, green and blue is 1:4.6:0.16.

Color reproducibility: Color reproducibility refers to the degree of color restoration of the LED display screen, which requires the displayed color to be highly consistent with the color of the playback source.

Whether there is mosaic and dead spot phenomenon: Mosaic refers to the small square squares that are always bright or always black on the LED display. It is a phenomenon of module necrosis. The number of dead spots is mainly determined by the quality of the LED chip.

Whether there are color blocks: Color blocks refer to the lack of color in a small area. The main reason is the quality of control IC, power supply and control circuit wiring.

Appearance of LED display: Appearance quality is the most intuitive and original evaluation of product quality, which can reflect the manufacturer's production process and material quality.

When choosing an LED display screen, taking these factors into consideration can help you find high-quality products more quickly and accurately.
