Cautions for Purchasing LED Displays

11 Jun,2020

When choosing LED displays, you should pay attention to the following aspects:


1. Cabinet Design

Cabinet design is very important for LED display. It contains the functions of circuit protection, safety, dustproof and waterproof. But what is more important is whether the design of thermal circuit system for ventilation and heat dissipation is good. With the extension of the boot time and the rise of external temperature, the thermal drift of components will increase, resulting in poor image quality. Good ventilation and heat dissipation design is the necessary index of cabinet design.


Therefore, when purchasing LED display products, you should choose regular manufacturers, which will be more secure in terms of quality, price and after-sales service.


2. Service Life

Under proper use environment, the service life of LED display can reach 100,000 hours, which can effectively save the maintenance and replacement cost of users. However, many consumers report that the service life of LED display products they choose is much shorter than expectations. This is because LED display brands on the market are very mixed. Although some LED screen display prices are low, their components are of poor quality. If the user purchases LED products with poor quality, it is easy to flicker or fail to shine. The service life and energy saving effect will be greatly reduced.


3. Grey Scale

Gray scale is an important index of dual primary colors and full color display screens. At present, the market is full of 16-level and 64-level grayscale displays posing as 256-level grayscale. The cost of LED screen is only 1/5 of the 256-level grayscale displays. The simple method to distinguish is to play a VCD of an intense sports scene to see if it can be seen clearly on the LED display screen.


4. Power Supply

Power supply is also an important component that affects quality in an LED display system. Under different temperature conditions, the working stability, output voltage and load capacity of the power supply are different. Because it plays the role of logistics support, its support ability directly affects the quality of the screen. Due to the difference in performance and stability, the prices of power equipment of different brands and specifications are quite different. You should not only focus on the low price without considering its performance and quality.
