LED display price leading factors

In today's society, the prices of products from all walks of life are uneven, and the quality of products also varies with prices, and the more parallel imports there are. This is especially true in the LED display industry. Displays are high-tech electronic products, and their production costs are relatively high. The reason for this situation is nothing more than fierce market competition, overcapacity, and oversupply. However, many customers are tempted by the low price of the product in order to covet the cheap price, which leads to the defective quality of the purchased product. So today, Lianhuiye Technology will teach you how to avoid the temptation of low-priced LED displays. First of all, we need to understand why the price gap of the same type of LED display screen is so large? In fact, the most important factor affecting the cost of LED display screens is components, and the highest cost of components is the lamp tube. Lamp tubes are the most used components of the display screen, thousands of pieces per square meter, and its cost accounts for about 60%-70%, so the quality of the lamp tubes will directly affect the price of the display screen . In order to earn a certain profit in the market, those manufacturers who sell low-priced display screens in the market will minimize the production cost and use inferior raw materials for production, so the price will be lower than other regular high-quality products. There are many reasons. Secondly, how can we tell if the display screen is made of high-quality light tubes, and what are its advantages? We can do it in two ways. The first trick: Look at the bracket of the lamp tube. At present, the mainstream bracket metals of lamp tubes on the market are silver-plated copper and silver-plated iron. Although there is only one letter difference between the two metals, there is a big difference in terms of electrical conductivity, thermal conductivity, corrosion resistance, and price. Because outdoor LED display screens often face harsh weather conditions such as rainy days, humid days, and sunny days during use, this requires components to have good performance, so as to resist the loss of the outside world. Strong corrosion resistance, good electrical conductivity and thermal conductivity can make components have longer life, better heat dissipation and less light decay. However, through the comparison test of Seejue Guangxu products, it is concluded that the performance of copper brackets is far better than that of iron brackets. But the price of copper brackets is more than 10 times that of iron brackets. For this reason, many manufacturers ignore the quality of devices, only pursue low cost and high returns, and choose iron brackets as raw materials, so there are so many "low-priced devices" on the market. The second trick: identify the bonding wire. The LED lamp needs to connect the chip and the pin through the connecting wire as the channel of the current, and the bonding wire acts as the connecting wire. Like the bracket alloy, the bonding wire is also an important part of the component, and its quality directly affects the quality of the lamp tube. The most common bonding wires used by manufacturers are copper wire, alloy wire and pure gold wire. Let's compare the differences between the bonding wires of the three metals. Compared with copper wire and alloy wire, pure gold wire is more inert, and has more advantages in oxidation resistance, back pressure resistance and manufacturing process, and is the best choice for LED device materials. However, due to the scarcity and high price of high-purity gold resources, the price of gold wire is more than 10 times that of copper wire, and the price of alloy wire is between gold wire and copper wire. Therefore, if you want to get LED devices with better quality, the price must not be so cheap. Therefore, if you want to buy high-quality LED displays, you must not blindly pursue low prices and ignore the cost-effectiveness of the products. You must avoid the temptation of low-priced LED displays, and always remember that the production cost price cannot be changed. .
