I heard that the LED display has been reduced in price recently. Mr. Zhang is going to buy a piece to enhance the overall image of his own fruit shop. However, as soon as the various products in the LED electronic market are dazzling, he does not know how to do it. Doing a preliminary understanding, I really feel that there is no choice. Finally, he came to a counter where he was doing activities. Because the price was much lower than other counters, he made up his mind to buy one. It didn't take long for the screen to have many problems such as dead lights, and he had to pay for it, which undoubtedly made him feel very annoyed.
After reading this little story, do you feel empathy, blindly pursuing low prices, but neglecting the price/performance ratio of the products, it really shouldn't, so you face the market's malicious low-price trap, you need to be vigilant!

So why is the price difference between LED displays so great? We know that the most important factor affecting the cost of LED displays is components, and the most cost-effective component is the lamp. Let's do the analysis with the powerful giant color S goddess product. The lamp is the most used component of the S Goddess, reaching more than tens of thousands per square meter; the cost of the lamp in the S Goddess product is as high as 50%-60%. Therefore, the quality of the lamp will directly affect the price of the goddess S.
Then the question is coming, why does the goddess of S must use high-quality lamps? Where is the so-called high-quality lamps? How to identify them? Let’s take a look at the professional analysis of domestic high-end lamp supplier Guoxing Optoelectronics. .
The first trick: look at the bracket
At present, the mainstream bracket metal of the market lamp has copper-plated silver and iron-plated silver. Although the two metals have only one word difference, there are great differences in electrical conductivity, thermal conductivity, corrosion resistance and price.

In the process of using the outdoor LED display, it is often faced with harsh environments such as rainy days and sunny weather. This requires the device to have good performance in order to withstand the loss of the outside world. Strong corrosion resistance, good electrical conductivity and thermal conductivity can make the device have the advantages of longer life, better heat dissipation and less light attenuation. Through comparison experiments, we can conclude that the performance of copper brackets is much better than that of iron brackets. However, the price of copper brackets is 10 times or more than that of iron brackets. To this end, many manufacturers ignore the quality of the device, only pursue low cost, high return, and choose iron brackets as raw materials, so there will be so many "low-cost devices" on the market.
The second measure: identify the bonding wire
The LED lamp needs to conduct the chip and the pin as a current path through the connecting wire, and the bonding wire acts as the connecting wire. Like the stent alloy, the bond wire is also an important part of the device, and its advantages and disadvantages directly affect the quality of the lamp. The most commonly used bond wires for manufacturers are copper wire, alloy wire and pure gold wire. Let's compare the differences between the bonding wires of the three metals.

Pure gold wire is better than copper wire and alloy wire. It is more inert, and it is superior in oxidation resistance, back pressure resistance and manufacturing process. It is the best choice for LED device materials. However, due to the high purity of gold resources, the price is high, the price of gold wire is 10 times that of copper wire, and the price of alloy wire is between gold wire and copper wire. Therefore, in order to get better quality LED devices, the price is certainly not so cheap.
Therefore, if you want to pursue a good quality LED display, don't blindly pursue low prices, because the cost price is there, no one can escape! S Goddess series surface mount product configuration is the national star photoelectric copper bracket + pure Gold line lamp, this kind of tube quality can be described as top, has played for 93 military parade, patented three-proof design, can pass MSL1, 500cycles severe thermal shock and other high-strength environmental tests, anti-back pressure and salt and alkali resistance , put into the market for 5 years, but after a rigorous market test.
Dry goods are shared, wit like you, I believe that you will make the most sensible judgment when you encounter the low price trap of LED display again in the future. (This article is a powerful macro submission)
The Hydrogel Screen Protector is made of imported material with TPU as the base material and is combined with hydrogel. It has super ductility and retractability, and can perfectly adapt to curved screens and screens with excessively curved edges, so as to fit perfectly without leaving white edges, and basically does not affect the touch experience. It has a strong and effective self-healing function, is impact-resistant, durable, and has better toughness, and has a certain buffering effect on the collision of sharp objects.
The Hydrogel Screen Protector uses glue and hydrogel to activate the stickiness to ensure a perfect fit without warping and leaving blanks, which is more beautiful. The Hydrogel Film is very thin. The responsive, ultra-thin design gives you a bare-bones experience. It's not as thick as a Tempered Glass Screen Protector, so the hydrogel screen protector won't affect the weight and feel of the phone.
In terms of hand feel, the Hydrogel Screen Protective Film has a hydrophobic and oleophobic treatment, so it slides relatively smoothly, and there is no problem in using APP or playing games. In addition, the liquid spilled on it can be slipped off by just tilting it, which is very easy to clean and maintain.
