[PConline News] "Yuan 1999 seems to be very cheap, is it worth buying?" "It looks like the panel is what the 10th generation is, is it very advanced and very good?" ... from last night, There are many friends who are asking me this question. It seems that no matter what the product "price" is, it is a big lethal weapon. Although it is only a relatively low-end TV product, it is not right. The accurate wording should be the main family. Such a product in the second TV market is only released on the Internet in a low-key manner. It will also attract the attention of many people. It seems that we have to believe the power of the brand.
Well, the main purpose of this article is not to Tucao, but to take this new product's slogan as an opportunity to introduce to everyone, in the end whether the LCD panel production line is higher the higher the representative of the more advanced. In fact, not only this brand, but many other TV manufacturers are introducing the panel of their own products, they will have similar keywords “the second generation LCD production lineâ€, and this does not give a good explanation, so , Many netizens consumers will think that the greater the algebraic number of LCD panel production lines, the more advanced they are.
First of all, to answer this question, we must clearly know the following aspects:
First, what is the LCD panel?
Perhaps in the impression of many netizens, the liquid crystal panel is such a large part of the entire display image of the LCD TV. It is not. The display system of the TV can roughly be divided into two parts: the liquid crystal panel and the backlight panel. The panel is composed of two layers of thin Glass substrates surrounded by a layer of liquid crystal molecules. In production, the glass substrate used has a fixed size, and various sizes of liquid crystal panels are formed by cutting. The liquid crystal panel can largely determine the brightness, contrast, color, and viewing angle of the liquid crystal display. The development speed of the liquid crystal panel is very fast. The liquid crystal panel has a close connection with the liquid crystal display, and its output, advantages and disadvantages, and market Many factors such as the environment are related to the quality, price, and market trend of the LCD monitor, because about 80% of the cost of a LCD monitor is concentrated on the panel.
When LCD TVs were just launched, LCD panel technology was concentrated in the hands of a few foreign companies. Therefore, at the time, the price of LCD TVs was in the hands of foreign manufacturers, and Chinese manufacturers suffered a lot from this. However, after the introduction of technology, there are now a large number of LCD panel manufacturers in China. Therefore, the current decline in the price of LCD TVs and the rapid expansion of Chinese TV manufacturers are becoming bigger and bigger.
Second, how to distinguish between algebraic LCD panel?
After that, because most of the cost of a TV is concentrated on the LCD panel, the LCD panel manufacturer naturally cuts more. The larger the scale, the lower the cost of production, and the more the profit will be. high. However, since the glass substrate used in the production has a fixed size, various sizes of liquid crystal panels are formed by cutting. This involves a problem: how to cut the glass substrate will make the raw material utilization rate higher, resulting in less scrap, the final product of the economic benefits are better, so the manufacturers according to the economic cutting size, the liquid crystal production line is also divided into different Algebra.
As we can see in the above figure, the economic cutting dimensions of different algebraic LCD panel production lines are different. Therefore, we can understand this way. If a manufacturer wants to build a high-algebra LCD panel production line, it means that this manufacturer believes that sales of large-size LCD panels will be higher in the future. This kind of production method will enable them to earn the most with the least cost. Profit.
However, different manufacturers of production lines, the size of the same generation of glass substrate is also not the same, how to call algebra is mainly determined by the manufacturers themselves, the industry does not have a unified standard. In general, the higher the panel algebra, the larger the size of the panel being cut, the greater the number of screens being cut, the higher the utilization and efficiency, and the price can be made cheaper.
Third, is the larger the algebra represents the production line of this LCD panel, the more advanced?
According to the foregoing, although algebra does not have a uniform standard in the industry, under normal circumstances, the production line of LCD panels with smaller algebra is certainly put into operation earlier. This earlier does not necessarily mean that the technology is lagging behind, because many times because of the market supply and demand reasons, or because of the reasons for the good product rate, may be in the process of production, during the production process will upgrade the technology of LCD panel production line In order to maintain the competitiveness of the product. After all, the time and cost of improving a production line is much lower than re-establishing a new LCD panel production line.
To give two examples: At the end of 2010, the Samsung Suzhou joint venture high-generation line project was approved, but at the time it was approved to build Samsung's 7.5-generation line, which was one generation lower than LG, Huaxing Optoelectronics and BOE Beijing 8.5-generation projects, but in the factory In the process of construction, Samsung responded to market demand and completed technical upgrading of equipment. In 2013, the factory was officially completed and put into production. It is already the 8.5-generation line; another example is Sharp and Foxconn, which often appear on TV commercials. The joint-venture factory, the world’s only tenth-generation LCD panel factory, is based on Sharp UV2A (X-Gen Super Crystal) and Quattron four-color technology, and the newly-launched Nanjing Zhongdian Panda Tablet Display The 8.5-generation line built by Science & Technology Co., Ltd. uses the LCD panel production line introduced from Sharp's top IGZO technology.
Finally, the author's advice to consumers who have television buying needs: Now that the writing of advertisement words and words is quite outstanding and level, everyone should keep a clear head when purchasing large appliances and meet Those "high-end" and "professional-based" advertisements must be careful to pay attention to the use of dunmu and ask acquaintances to know about their friends so as not to buy products that are different from those expected in their own minds.
Summary: For LCD panel production lines, the first few generations are just a “name†and “code number†of manufacturers for their own LCD production lines. The higher the algebraic number is, the more the number of large-size panels they cut and the less environmental-friendly scraps are, However, it does not mean that "the higher the algebra, the more advanced the LCD panel production line is." Don't be fooled by advertisements that are full of "high-end technical terms".
