Problems that must be paid attention to when purchasing full-color LED display
Full-color LED displays are not unfamiliar to many people, and they often appear in our lives. However, when it comes to the purchase of full-color LED displays, most people are still in the fog, and they don’t really understand that they should How to compare the inquiry and analyze the quality of the LED display. Today Winbond Yingguang will take you to understand the issues that should be paid attention to when purchasing a full-color LED display.
1. Don't just look at the price when buying a large screen
Price may be an important factor affecting the sales of large LED screens. Although everyone understands the principle that you get what you pay for, when you choose LED display manufacturers, you will still unconsciously move towards lower prices. The huge price difference causes customers to ignore quality. But in the actual use process, you may only remember that the price difference is actually the quality gap.
2. the display "same model" is not necessarily "same product"
In the process of selling large LED screens, I often met customers and asked why your price is so much higher than others for the same model of Huarong Optoelectronics display. In fact, I was shocked, because I quoted customers based on company channel prices. I discovered by chance that the so-called products of the same model are actually different. Let’s take the P4LED display as an example. Generally speaking, the P4LED large screen we are talking about refers to a pixel pitch of 4.0mm, but there are displays with a pitch of 4.81mm, or p4.81, on the market. Customers who don’t understand the outside world, Some sales people use blindfold method, claiming to be P4 full-color LED display. In this way, the quotation gap will be more obvious, and many uninformed customers think that they have bought good products at low prices.
3、Technical specification parameter value is not as high as possible
Generally, customers who purchase LED displays will select several manufacturers for evaluation, and then decide on Huarong Optoelectronics LED large-screen suppliers. The two important items in the evaluation are price and technical parameters. In the case of similar prices, technical parameters become winners and losers. Many customers think that the higher the parameter value, the better the quality of the display. Isn't that the case? Let's take a simple example, the same is the Huarong Optoelectronics indoor P4 full-color display, in the brightness value of the display. Some manufacturers will write 2000cd/square meter, and some manufacturers will write 1200cd/square meter. Is 2000 better than 1200? Answer 1 is not necessarily because indoor LED screen brightness requirements are not high, generally between 800-1500. If the brightness is too high, it will dazzle the eyes and affect the viewing. In terms of service life, too high brightness can easily overdraw the display life in advance. Therefore, the reasonable use of brightness is the correct answer, not that the higher the brightness, the better. For the same model, some parameters are required, such as LED light brand/package, scanning method, power refresh rate, power consumption, gray scale, etc. The price will not be the same for different parameters.
4、Display production and testing are not as short as possible
Many customers who buy LED full-color screens just place an order and want to get the goods right away. We understand this mood well, but the large LED screen is a customized product, and it needs at least 48 hours of inspection and testing after the production is completed. The LED display has been added 24 hours to the national standard to achieve 72 hours of non-stop testing. Too short delivery time generally has two problems: one is that it has not passed sufficient inspection and testing, and the failure rate in later use will definitely be relatively high; but some manufacturers do not have enough of the same batch of goods, which may be in order to receive Place an order to use products from a different batch. In this case, the display screen will have obvious color difference, which greatly affects the display effect of Winbond Yingguang LED large screen.
The above is the full-color LED display related precautions that Winbond Ying Optoelectronics brings to you today. I hope to have some help for those who want to know more about LED display knowledge. If you have more requirements or technology for large LED display screens If you have any questions, please feel free to consult Winbond Ying Optoelectronics, we will try our best to serve you.
