What is LCD module?
Date:2019-04-26
LCD module is: screen + backlight module.
The display unit of LCD TV is LCD module, and its low temperature is equivalent to CRT picture tube.
Other parts include power supply circuit, signal processing circuit, and of course, the shell.
The module is mainly divided into screen and backlight module. The two parts are assembled together, but they work independently of each other (i.e. the circuits are not related).
The principle of liquid crystal display is that the backlight module emits uniform surface light, and the light is transmitted to our eyes through the liquid crystal screen. The function of the screen is to process the light by pixel to display the image. Both parts contain a large number of components, which will not be discussed in detail here. At present, sharp has the best technology, followed by Samsung and Sony.
LCD panel expertise
Usually, when we sell LCD, there are always people who ask about the level of your screen. You may casually say that it is A-level or a + level. In fact, this kind of answer is unprofessional. If the consumer is a professional consumer, he would disdain to talk with sales like this. He would just walk away. If he can make a deal, nine times out of ten, the customer already knows about the market outside, Just let you out of the lowest price, and do LCD sales, we must do valuable salesman, blindly low price shipping, is not an excellent salesman, only let customers believe, let customers believe your professional, your service, you can be successful!

If you want to be a professional LCD salesman, you must have a deep understanding of the professional terms of LCD. You need to know more than the customers. At least you can't understand the terms that the customers say. Here are some proper terms of LCD I collected. You can understand them according to the models you sell
LCD panel
LCD panel is the main component of LCD, accounting for nearly 80% of the cost of LCD. At present, there are not many manufacturers with panel manufacturing technology in the world. Only sharp, Sanyo, Samsung, LG Philips, Taiwan's Youda and other manufacturers have core technology. Most LCD displays are assembled and produced with their panels.
Experience: we can prove some of the problems we encountered in the sales. After the LCD panel was artificially damaged, the after-sales service of major manufacturers answered that the charging standard of (LCD + manual screen replacement) is close to or more than the cost of a new LCD, so that customers can understand the importance of good or bad LCD, and the importance of three-year free service! Not long ago, we met a couple in Danjiangkou who had a fight and broke the screen and wanted to replace it. The customer service of the manufacturer replied that it was artificially damaged and the charge was 1000 yuan. It was suggested that the customer should not repair it and sell the circuit board before buying a new one. There was also the "BenQ" LCD that we had sold for four years before. Many customers found that the screen did not light up, turned black and the light tube turned yellow after using it for one year, Last week, we met a customer's va721 screen in Ezhou with gray shadow. Because it was free for three years, it was replaced with a new screen for free
At present, the quality and value of the panel can be divided into three grades: Sanyo and sharp of piggy belong to the first grade, which are mostly used in high-end products, such as Eizo, Sony, youpai (VP, VG Series), and the price is relatively high; South Korea's Samsung, LG and Philips belong to the second level, most of which are used in the displays sold with brand computers; Taiwan manufacturers such as Youda are in the third category. Qimei, Hanyu Caijing get a lot of OEM orders with cost performance; As far as I know, there is another kind of five generation line panel produced by nec-sva (Shanghai radio and television) joint venture. The price is particularly good. Most of the models with super low price can be seen in our market are this kind of panel
