One year ago, an editor of a computer professional media intended to be a topic about the LCD monitor. He ran many vendors, and found that the number of manufacturers of computer standard liquid crystal displays was found to be very small.
After half a year, it seems to be a minor, the liquid crystal display on the market also issued a dazzling brilliance, and the Zhongguancun Electronics market even passed the news.
Why is the LCD computer suddenly be swear?
Prior to this, Haier has launched a computer specially designed for the SOHO family. It adopts a 15-inch LCD monitor, advocating a health concept; ZHAI also designs "Yun Tian" series of business computers, but these Didn't have any impact on the market. It is some brands abroad, and some models are configured with liquid crystal displays, such as IBM, Coop, and Dell, etc.
In May of this year, with the summer approach, the market explodes news: LCD monitors appear in home computer configurations in mainstream prices. First, Lenovo announced the launch of two LCD display computers, and the Great Wall also announced the full line of household computer standard liquid crystal displays. The movement of the two major manufacturers, let other manufacturers in the wait and see have awakened, as if it is a order, the liquid crystal display on the market also issued a dazzling brilliance, and the Zhongguancun Electronics market even passed out of the goods, the LCD computer market It is activated.
On July 7, Lenovo has burst a big cold door, and the publication of 1.8 billion yuan to buy more than 600,000 sets of liquid crystal displays, completed China IT's first big purchase order, TCL is not asked, July 21, in Huizhou Samsung, LG-Philips and Genesis LCD manufacturer concluded strategic alliances.
A series of movements make people feel that the LCD monitor "hot", "LCD era" with computer in China seems to arrive overnight.
Commercial interest should be an important reason that leads to the rapid flour of the LCD monitor. In order to maintain people who purchase the computer "Psychological Line" (in this "psycho-line", the manufacturers have a rich profit), the LCD monitors become this summer The computer is a shining selling point, which also provokes some display manufacturers to get rid of the price of the flat display, follow the boom.
LCD monitor, can not be injured
The principle of the liquid crystal display is to utilize the physical properties of the liquid crystal. When energizing, the alignment becomes order, making the light easy to pass; it is arranged in the time of electrification, preventing the light from passing. Image can be displayed on the screen by combining the pass and the unrivaled combination.
In the publicity of the manufacturers, the LCD monitors are depicted into energy-saving, environmentally friendly, and unfrigerated leading stylish tender girls, but for her defects, it is a mouthful.
Secret injury
The first is the price, the price of the liquid crystal display can be described as "noble price" in the monitor family, just 15 inches of 3,000 yuan, while the same size flat display is just about a thousand yuan. Experts analyze the main reason for the high reality of the liquid crystal display is that there is low in the manufacturing process, causing costs that cannot be lowered. At present, only Japan and Taiwan's manufacturers, and the technology is not fully spread, and there is no competitive situation in large-scale production, and there is also a big difference in quality. In the international market, the difference between different grades can reach several tens to hundreds of US dollars. Some liquid crystal display "vicious" in the domestic market have fallen, in fact, is a low-quality product.
Secret injury
The digital interface of the liquid crystal display is not cold. In theory, the liquid crystal display is a pure digital device, and the connection to the computer host should also be a digital interface, and the advantages of using the digital interface are self-evident. First, the signal loss and interference during analog-to-digital conversion process can be reduced; reduce the corresponding conversion circuits and components; seconds without clock frequencies, the adjustment of the vector.
However, the interface of most of the liquid crystal display on the market is an analog interface. There is a transmission signal is susceptible to interference, and the analog-to-digital conversion circuit needs to be added inside the display, which cannot be upgraded to a digital interface. Moreover, in order to avoid the occurrence of pixels, the clock frequency must be done, the vector is completely consistent with the analog signal. In addition, the digital interface of the liquid crystal display has not yet formed a unified standard, and the display card with digital output is not more common on the market. In this way, the key to the liquid crystal display is difficult to give full. In terms of current, the result of spending in advance is to spend high prices.
Mandatory
The visual deflection angle is too small. Early liquid crystal displays can only be 90 degrees, only from the front view, and there will be large brightness and color distortion from the side. Nowadays, the liquid crystal displays on the market can generally be around 140 degrees. It is enough for personal use, but if several people watch, the problem of distortion is displayed.

It is easy to generate image tailings.
The response time is a special indicator of the LCD monitor. The response time of the liquid crystal display refers to the speed of each pixel point of the display to the input signal, and the response time is short, and the image tail is not generated when the moving picture is displayed. This is important to play the game and see the image of the fast action. A fast enough response time can guarantee the coherence of the screen. At present, the general liquid crystal display on the market has a big breakthrough than before, generally 40ms.

Do you want to call a flash? This joke is the brightness and contrast of the liquid crystal display. Since the liquid crystal molecules do not illuminate themselves, the liquid crystal display needs to assist in the external light source. Generally speaking 140 lumen is enough to be in place. Some manufacturers have a gap between parameters and actual standards. Here to explain that some small-sized liquid crystal displays are mainly used in laptop, using two lamps to adjust, so their brightness and contrast are not very good.

LCD "bad point" problem. The material of the liquid crystal display is generally glass, which is easy to break, plus every pixel is very small, often causes individual pixels that are broken, commonly known as "bad point", this is unmissive, only replacing the entire display Screen, and replacement is often very expensive.
LCD is flat, radish cabbage has good
The liquid crystal display has been a mysterious veil for a long time, and it is only the advantages of its mystery and radiation, no flash, but the user is still "do not know the true face of Lushan." Recently, as the liquid crystal display went down the altights, it gradually unveiled the veil, and the looks of their appearances in front of the majority of users, the liquid crystal display is compared with the CRT display, which is Chunlan Qiuju, each has a winner. Traditional CRT monitor technology has developed to be very mature today, although there is a natural beauty like a LCD monitor, but in some aspects, there is still its own absolute advantage. Especially the quality and price of the flat display, it has been able to accept the public, even if it is very unplanned radiation problem, it is controlled below the safety standard. There is data indicated that the radiation of the cosmic rays per day will be far more. The radiation of the CRT display.
An unquestionable fact is that if the LCD monitor has an absolute advantage, then in the competitive household TV market, I am afraid that I have already been the world of LCD monitor.
From now on, the advantages of traditional CRT monitors in color and fast image display are unmatched by LCD displays, so the CRT display is still their first choice for compared professional users of these aspects. The liquid crystal display will not completely replace the status of the CRT display, and can only be unable to lead the CRT display "melon" market.
