The best led screens you can buy are not necessarily the best for you

LED is a kind of semiconductor which can convert electric energy into light energy. Its characteristics are very obvious, with long life, high luminous efficiency, low radiation and low power consumption.Because of these characteristics, it is widely used in the LED display industry.Here‘s what to look for when choosing an LED display.

LED life: first of all, there is a big mistake here. Most people believe that LED and IC, the main materials of LED display, have a life of 100,000 hours, running on 365 days/year and 24 hours/day, with a service life of more than 11 years. Therefore, most customers only care about using well-known LED and IC.In fact, these two conditions are only necessary, rather than sufficient, because the reasonable use of red, green and blue lamps is more important for LED display screens. For lamps with different colors, it is more important for a good display screen to make them work in the best condition.The reasonable adjustment of IC also helps to overcome the problem of unreasonable wiring of PCB.Just as a car with good engine and circuit control does not necessarily make a good car.At the same time, the power supply is also very important. The operating stability, output voltage value and load capacity of the power supply are different under different temperature conditions. As it is responsible for logistics support, its guarantee capacity directly affects the quality of the screen.

Abide by the national standard: the general specification of LED display is the ministerial standard in 1995.More than two decades later, there are many companies that still follow the same standards.Technology continues to improve, LED display technology is no exception, from today‘s display technology, the standard is no longer the standard.Take the outdoor LED display screen with the distance of 10mm as an example. Generally, the screen with the standard resolution of 800x600 is 48 square meters, with 10,000 points per square meter. According to the national standard, there can be 144 points out of control.More out of control means that LED displays are less effective, so presumably fewer people will pay for them, or no one will.

3. Cost performance: provide or require the manufacturer to analyze the data of the project installation and application environment, predict the feasible events, put forward preventive and solution measures, and then make a comprehensive evaluation of the whole project plan.

4. Grayscale: the grayscale of two-tone and full-color LED display is an important indicator.The market is currently flooded with 16 - and 64-bit grayscale displays masquerading as 256 shades.The control cost is only 1/5 of the gray level of 256.The easiest way to tell the difference is to play a high-definition video and see if the LED display can see it.

5. The best is not necessarily the most appropriate: all purchase behaviors are derived from demands. When selecting LED display screen, the premise is to meet the project needs.The right one is the best one, and don‘t blindly go for the highest configuration, because there are so many features you may not need.

6. Practicality: application is fundamental. As an application software upgrade, hardware maintenance, maintenance and maintenance, LED display manufacturer‘s support is indispensable.When buying the display screen, pay more attention to these aspects. If there is no maintenance guarantee for the product, once the LED display fails, the consequences will be unpredictable.
