How to identify the performance of LED display

LED display screens have become an important tool for information display in modern society with their excellent display effects and wide range of application scenarios. However, the quality of LED displays on the market is uneven, and how to identify its performance has become a concern for consumers and businesses. The following are some key indicators to help us evaluate the performance of LED displays:

Pixel out of control point

Out-of-control pixel points include blind points and bright points, which are an important indicator of display quality. For small-pitch LED screens, the industry standards are more stringent, and the out-of-control rate should be controlled below 1X10-5. During the warranty period, professional equipment can be used to detect the out-of-control pixel points of the display to ensure the integrity and clarity of the image.

Protection level and safety

The protection level mainly refers to the waterproof and dustproof capabilities. The higher the IP level value, the better the protection performance. In terms of safety, the leakage current should be kept below 3.5mA at 1.1 times the rated voltage, and the electrical strength should be able to prevent insulation breakdown at 1500V for 1 minute. Take you 5 minutes to understand LED IP levels.

Energy consumption and energy efficiency

A high-quality LED display should have low energy consumption and high energy efficiency. Power consumption can be effectively reduced by using LEDs with low Vf values, constant current driver ICs with low Vds values, low impedance PCB design, and module operating voltages of 4.2V or 3.8V. In addition, the PFC (power factor correction) of the switching power supply should be above 0.95, and the conversion efficiency should be no less than 0.85 to ensure effective use of energy. Here are the LED display specifications.

reliability

The reliability of a display is a key factor in determining its quality. High-quality materials, reasonable thermal design, redundant design (such as switching power supplies, controllers, PCB lines) and material tolerances (at least 20% margin) are all important measures to improve reliability. In addition, through reliability simulation verification tests, such as life testing and related certifications, the stability and durability of the display can be further ensured. What should you consider when customizing LED digital screens?

Through the comprehensive evaluation of the above aspects, we can more accurately judge the performance of the LED display and select products with high cost performance and high quality. Whether it is used for advertising display, public information release or interior decoration, a high-performance LED display can provide more stable and longer-lasting services.
