购买液晶显示器必须谨防的七大陷阱（The seven traps that must be taken care of when buying LCDs）The seven traps that must be taken care of when buying LCDsAny product price depends largely on the cost, reduce the cost is the most effective way to improve profits, so all kinds of products are easy to cut corners on the cost of links, the liquid crystal display is no exception. Seemingly similar products, different manufacturers, different models, there are hundreds or even more than 1000 yuan gap, the reason is that there is a difference in cost.The panel level is the easiest to cut cornersA liquid crystal display seventy percent of the cost from the liquid crystal panel, a liquid crystal panel is a core component of liquid crystal display well, of course it is most likely to cut corners of parts.First of all, there are differences in performance of LCD panels, the performance of a more general LCD panel, but also a high angle of view, high contrast panel. Performance effect of liquid crystal display or not, basically by the choice of what the panel decided, bad JS is likely to be some shoddy, low performance products for superior performance products and Huyou expensive for such products only need to carefully check the information, the real performance can clear the product easy to distinguish.In addition, the liquid crystal panel the same performance when the sale of the factory was set at different levels, and different levels of panel prices are different, in order to reduce the cost only need to order a low level panel on the line. From the panel appearance is difficult to distinguish between the grade of the panel, so after all the panel assembled into a product from the sale is difficult to see the difference.To distinguish the grade of the panel, mainly to see the number of pixels of the panel, the less the number of pixels, and promised no highlights panel level is higher. The high level panel itself is light small, no other problems such as spots, color. The lower level of the panel have more or less problems, such as bad or more, there are stains, light is hard. That is to say, this is when the actual business classification panel factory by choosing to distinguish, good product quality, high grade, higher prices, or low goods or defective products, the price is certainly low. This classification standard is widely used in IT product parts.In fact, there are many LCD display giants are not specially customized proprietary LCD panels, but also with other two or three wire manufacturers in the same panel manufacturers procurement. But this kind of companies often pay much attention to the selection panel, is often selected a small part in a batch of LCD panel manufacturers in this part of the boutique course quality is higher than other products, high cost, the price of more expensive and very easy to understand.In fact, for their own use panel manufacturers quality often have a mental picture, agent told dealers to sell under the condition that a batch of products, because the panel quality is poor, prone to bad dark spots and other issues. Of course, the faster you sell, the better. If the panel quality is good, manufacturers may also temporarily implement insurance policy on a batch of products, because manufacturers understand that these products are good, and the rate of rework will not be high.Hidden tricky in LCD product packagingDo not think that the product packaging is a box so simple, the product packaging involves many issues such as safety, environmental protection, in the mass production of industrial products, packaging is also very important, the cost is not low. If you dont see the discarded boxes, you can sell a few cents a kilo. A lot of people are scrambling for it, arent they?Liquid crystal display good packaging is usually thick, in order to ensure the handling time will not be damaged, the raw materials are usually recyclable, environmentally friendly material, can find the logo on the packaging material circulation in general. In the packaging printing, pay more attention to the manufacturers usually printed on the built-in display appearance, but also as far as possible to provide information such as display, such as the type, size, weight, the approximate performance, the printed text is also a cost of printing less cost lower. More attention will also be paid to the beauty of the outer packing,The printed content can even include pictures and other information, very delicate. And in the outer packaging, Jerry manufacturers generally try to simplify these things, an outer package can be used for more than the specifications of similar products.In addition to the packaging itself, the internal filling material can not be ignored. The most common materials are recycled paper and foam plastics. Recycled paper is more expensive, and is usually seen on high-end displays. The foam is very popular. Because it is a by-product of petroleum, the
