Tips: I only went to one store, and the LCD panel I went to was limited to the prototype (so different batches of screens could not be confirmed), and the models collected were not complete. Welcome netizens to supplement their testimony!

Trend of LCD TV panels and manufacturers in 20 1 1 year
LCD TV panel manufacturers constantly announce their high-end products such as 3D, 480Hz, ultra-thin design and direct LED backlight to the world. But on the other hand, it is also developing to low-end and low-priced products, aiming at emerging markets. These specifications with low brightness and low color saturation further depress the panel price and are gradually affecting the development of panel industry technology and business model.
According to the report of DisplaySearchSquarter Large-AreaF LCDProduct Roadmap, panel factories are tailoring low-end panel products for emerging markets such as India, Brazil, Chinese mainland and Russia. Compared with the general specifications of 450-500 nits, the panel brightness in emerging markets can be reduced to 350-400 nits, and the color saturation can be reduced from 72-75% to 65-68% (according to NTSC standards).
With the annual shipment of LCD TVs approaching 200 million units, the markets in some developed countries are saturated, so the products of panel factories are also developing towards M-type. One end develops to high specifications, stimulating the demand for replacement in developed markets; At the other end, we also expand low-standard exhibits to meet the new needs of emerging markets at low prices.
Li Xinlin, senior analyst of DisplaySearch, said that at 20 1 1, it is more important to provide the right specifications and prices in the right market because of the different consumption preferences of developed countries and emerging markets.

Source: DisplaySearchQuarterlyLarge-areatftlcdproductreport.
Panel manufacturers LGDisplay, AUO, CMI and BOE have all invested in the TV panel battlefield in emerging markets. The design direction of low-order panel includes: using diffuser instead of brightness enhancement film, using larger LED package to improve brightness, reducing the number of LED chips, reducing the thickness of glass, or modifying the structure of color filter.
The quarterly roadmap report of large-area LCD products also puts forward the latest development trends of various panel factories:
Sharp: The only panel factory with 10 generation line plans to produce six 70 "W panels on this line. At present, the production line mainly produces 40 "W, 60" W and 65 "W. ..
AUO: Actively develop a 58 "panel with the aspect ratio of 2 1:9 and 120Hz, which is called" CinemaScopeHD "and its target market direction is 3D, home theater and Internet TV market. LG Display and Samsung also have ink on it.
Samsung: It produces a 43-inch public display panel on its seventh-generation production line with an aspect ratio of 4: 1. Samsung has also developed a new liquid crystal structure called PLS, which combines horizontal and vertical electric fields to create amazing visual effects.
BOE: With the opening of the production capacity of the Sixth Generation Line, BOE also ranks among the suppliers of 32-inch LCD TV panels, and adopts FFS technology for wide viewing angle.
120Hz frequency doubling has become the mainstream specification for panels over 40 ". 240Hz for shutterglass)3D TV panel. The high-end product will be a direct LED backlight design with 480Hz and area dimming.
Sharp strengthens UV2A technology, the aperture ratio can be increased by 20%, the contrast can be increased to 5000: 1, and the response time can reach 4 ms ..
LG Display actively promotes its PatentRetarder3D LCD panel, and plans to launch a series of high-resolution panels ranging from 32 "to 55". AUO is developing to both ends of 32-inch HD and 65-inch FHD. Other panel factories mainly focus on shutter 3D technology, and the new and unique beauty is developing to 120Hz 3D TV.
20 1 1 misunderstanding of new concept TV purchase
The biggest highlight of 20 10 TV products is the rapid popularization of LED and the listing of 3D TV. In this paper, the author will discuss six controversial issues, including plasma and LCD TV, double-speed drive, all-in-one machine and panel effect, as well as new issues such as LED, CCFL and 3D TV. For many netizens who buy flat-screen TVs for the first time, these problems are not all, but necessary.
Will 3D TV be popularized rapidly?
Since the major brands were officially launched at the CES show in America at the beginning of the year, 3D TV has become the hottest topic in the flat-panel TV market. At present, in the terminal market, brands include Samsung, Sony, Sharp, Panasonic, LG and Hisense. Have launched their own 3D TV products. From the actual price point of view, the price of a 46-inch 3D Blu-ray player, two pairs of glasses and 1 3D Blu-ray disc has dropped from 19999 yuan at the initial stage of listing to about 16999 yuan at present.
Technically, 3D technology didn't appear in the last two years. In fact, there have been technologies such as color difference 3D, polarized 3D and active shutter 3D for a long time. Just now, Avatar gave us a good 3D lesson. I believe that many netizens who have seen the 3D version or iMax version of Avatar will still remember it. To see a good 3D effect, active shutter 3D is undoubtedly the first of the above three 3D technologies, which has neither the color cast effect of chromatic aberration 3D nor the resolution problem of polarized 3D. At present, active shutter 3D technology is mostly used for 3D TV in terminal stores.
3D TV has been widely questioned since its launch, and the main reasons are undoubtedly reflected in the following three aspects: first, the source of 3D movies; Second, watch TV with glasses; The third issue is the price. The source problem of 3D film is undoubtedly the biggest obstacle to the popularization of 3D. At present, there are only a handful of 3D film sources on the market, and even fewer 3D Blu-ray discs. Even online downloading, which is highly praised by Chinese people, is far from meeting the demand. Buying a 3D TV at a high price is not the original intention of consumers, but the inability to see 3D content.

After the appearance of 3D TV at CES, a columnist in the American household appliance industry said: "It is not easy to convince the whole family to wear 3D glasses to watch TV!" Not to mention whether home users are willing to wear glasses to watch TV, the "sequela" brought by wearing glasses alone is enough to alert users: the flashing frequency of 3D glasses and fluorescent lamps is meticulous, and it is easy to be used when turning on the lights; Watching with 3D glasses may cause eye discomfort for some users.

The author has heard some consumers complain: "My it is running at home, so I will send 2 pairs of 3D glasses. How can it be enough?"? It is unreasonable to buy 1 pair of glasses for nearly a thousand yuan! " In fact, not only 3D glasses, but also the price of 3D TV itself. Take a 46-inch TV for example. Excluding all accessories, the stand-alone price is1.20,000-1.30,000 yuan, which is indeed much higher for ordinary high-end 2D TVs whose 46-inch TVs have already fallen below 10,000 yuan.

From the point of view that CCFL LCD TV replaces CRT TV and CCFL TV replaces LED TV, technology upgrading has always been the result of manufacturers' pursuit of higher profits. 3D TV represents higher profits and will inevitably become the "next-generation product" that manufacturers focus on. Judging from the current development of 3D TV, there is still a long way to go to gain the final recognition of consumers and eventually occupy most of the market.
Is LED necessarily better than CCFL?
When LED backlight LCD TV was first introduced in 2009, many manufacturers used to call it "LED TV" directly. Even if it is biased, it is finally recognized by consumers. In fact, the difference between the so-called "led TV" and the traditional "CCFL TV" is that the backlight of CCFL cold cathode fluorescent lamp is changed to LED backlight, and LED is not necessarily a precise technology. What should really be called "led TV" is the mode of LED backlight and LED panel, that is, outdoor billboards (such as the scoreboard of the stadium), but unfortunately, due to the relationship between cost and technology, it is difficult to become a household name product.
Position indication of direct LED/ side LED TV light source
According to the manufacturer, the biggest advantages of LED TV are good color, high contrast, low power consumption and thin body. In fact, LED TVs are also divided into side LED TVs and direct LED TVs. The only difference between the two is that the LED backlight of the former is located around the LCD panel, and the LED backlight of the latter is located behind the LCD panel. The four advantages mentioned above are actually the advantages of good color and high contrast. The advantages of side-mounted LED TV are low power consumption and thin body.
Direct LED TV is often ignored by consumers because of its high cost and no appearance advantage. Since the advent of LED TV, there are only a handful of TVs with LED direct backlight. At present, only Toshiba SV650 and Sharp LX7 10/LE700 are left. Direct LED TV has no ultra-thin body, so it won't be "love at first sight" for many consumers.
Samsung C9000 series side-mounted LED TV is extremely slim.
Side-mounted LED TV is undoubtedly the mainstream of LED TV at present, and almost every LCD TV manufacturer promotes it as the main product. In my opinion, the side-mounted LED adopts light guide plate technology, which easily leads to uneven screen brightness and light leakage, which greatly affects its image quality and actual life. Judging from the actual picture quality, the author thinks that side-mounted LED has no overwhelming advantage compared with CCFL TV, and it is not commensurate with its high price.
Many netizens may say that modern home improvement style emphasizes simplicity and refreshment, and thin TV is naturally more popular than thick TV. This view is correct, but it is based on higher price, without improving image quality and higher service life risk. As for whether it is worth it, it is up to consumers to measure it themselves.
Plasma TV will be eliminated?
The author once heard the funniest true story that can best represent the embarrassing situation of plasma TV: a newly married couple is going to buy a TV, and then my colleague recommended a TV with good picture quality, and then my colleague recommended a plasma TV, and then the couple exclaimed, "Aren't all TVs LCD?" What the hell is plasma? Do you have an LCD TV? "A series of questions made colleagues suddenly speechless. The most important reason why the title of this article does not use "misunderstanding of LCD TV purchase" is that TV can't avoid plasma.
The most important difference between LCD TV and plasma TV is the difference in display principle. LCD TV uses passive light, so it is necessary to arrange a light source system behind the LCD panel. The light emitted by the backlight passes through the light guide plate, liquid crystal molecules arranged at different angles and other original components, and finally displays a color picture on the screen. Plasma TV adopts active light emission, and the plasma panel is designed as two-layer glass plate filled with mixed gas. Voltage is applied to the gas to generate ionic gas, which reacts with the fluorescent powder in the substrate and finally produces a color image.
Introduction of new technology of Panasonic VIERA plasma TV
LCD TV and plasma TV are not perfect in implementation technology, and both have their own advantages and disadvantages. The principle of plasma TV forces it to use high-voltage circuit to activate mixed gas, which inevitably leads to the problems of high power consumption and short life. The principle of LCD TV determines that its liquid crystal molecular response will be delayed, and inevitably there will be problems of picture tailing and insufficient color. Compared with LCD TV, plasma TV has the advantages of wider color gamut, more accurate picture color, faster response speed, and no rapid picture tailing, but it has the disadvantages of higher power consumption and shorter life.
Introduction of new products and technologies of Panasonic VIERA plasma TV 20 10 in autumn and winter.
For many sharp-eyed netizens and game enthusiasts, inaccurate colors and trailing dynamic pictures are unbearable. Therefore, there is a widespread saying that professionals buy plasma and laymen buy LCD. But for the whole market, after all, high-end and picky users are a minority, and mass and civilian users are the majority, which leads to the closure of plasma manufacturers (such as Pioneer), and the share of plasma TVs is getting less and less, but this does not mean that plasma TVs will be eliminated.
New product configuration of Panasonic VIERA TV 20 10 in autumn and winter
In Chinese mainland, plasma TV currently accounts for about 65,438+00% of the total sales of flat-panel TVs. Perhaps this figure is so insignificant, but we often ignore the fact that the number of manufacturers pushing LCD TVs is much higher than that of plasma TVs. At present, only three manufacturers in China sell plasma TVs, namely Panasonic, Samsung and Changhong. Among them, Samsung and Changhong are mainly LCD TVs. Only Panasonic is the main promoter of plasma, which is good for cakes. Are you willing to grab 90% of the big cake with a dozen people, or are you willing to enjoy about 10% of the small cake?
When 3D TV gradually came to the front desk and began to be accepted by consumers, plasma TV has been expected for its dynamic and image quality advantages, and some even commented that 3D is an important way to make plasma TV turn over. Therefore, to sum up, "plasma will be eliminated" is undoubtedly a false proposition, at least in the foreseeable three to five years, plasma TV can not completely withdraw from the market.
120Hz is more advanced than 100Hz?
Now we often talk about the double-speed driving technology, which refers to a technology to optimize the dynamic effect of LCD TV through motion evaluation and frame interpolation compensation. Double speed drive technology is to double the refresh frequency of LCD drive. In China, the TV signal is in PAL format, that is, 50Hz, and the double-speed drive is increased to 100Hz, that is, 100 frames are displayed every second. If the TV signal in the United States or Japan is NTSC, the image signal is 60Hz, and the double-speed drive is 120Hz.
Detailed explanation of 100Hz double-speed frame insertion technology
This is due to the different TV signal formats adopted by different countries and regions. The principle of double speed technology between 120Hz and 100Hz is similar, which does not mean that 120Hz is more advanced than 100Hz. Similarly, the principle of 240Hz and 200Hz quadruple speed drive technology is similar, which does not mean that 240Hz is more advanced than 200Hz.
For a film source with an original signal of 50Hz, if the TV only supports 120Hz/240Hz, then the double speed effect can't be formed, which is what we usually call "invalid double speed". Only one TV can support 100/ 120Hz and 200/240Hz at the same time can it support different signal sources. For example, a consumer often watches cable TV at home and plays games with Sony PlayStation. Because the former output signal source is 50Hz and the latter is 60Hz, the double speed effect of supporting one signal source will be discounted.
The signal output of Sony PS3 and other game devices is 60Hz.
I would like to remind netizens that the double-speed effect of many domestic brand TVs is only effective for 60Hz signal sources, so you must not completely believe the salesman's nonsense when purchasing. For example, the official interpretation of "true +240Hz" by a domestic brand is: true +240Hz= vertical 120Hz+ horizontal 120Hz. First of all, it can be concluded that this statement not only shows that it is invalid for 50Hz signal source, but also steals the concept. The realization method of double speed technology is frame insertion, that is, adding an operation frame or a black frame to two pictures.
The task of salespeople is to improve sales performance. As for after-sales, it is not their responsibility. Therefore, many salespeople may blow up their products when buying TV sets. Therefore, netizens need to be vigilant and alert when buying TV. If they think more about salesmen, they can find their shortcomings.
Taiwan Province province panel effect is not good?
Speaking of panels, it is a problem that many netizens will struggle with, especially when they hear that their favorite machine is actually the Taiwan Province screen. It is estimated that many netizens will retreat. If LCD panel manufacturers are classified, they can be divided into LG S-IPS, Samsung S-PVA, Sharp, Panasonic IPS, Chi Mei and AUO. It can be divided into Sharp and Panasonic in Japan, Samsung and LG in South Korea, Chimei and AUO in Taiwan Province Province.

Sharp is known as the "father of LCD", and its LCD panel output is small, so it is generally considered as the best quality LCD panel by netizens. At present, the panels of Sharp Kameyama Eighth Generation Line and Sakai Tenth Generation Line are mainly used for Sharp's high-end LCD TVs and Sony's high-end LCD TVs. Many netizens asked whether a certain model used Sharp's original Japanese screen. In fact, the simplest standard is how high the price of this TV is.

The output of Chimei AUO LCD panel in Taiwan Province Province is relatively large, coupled with the advantages of labor and export tariffs, the cost and price have been low for a long time, which is often ignored by netizens. At present, Taiwan Province screens are mainly used in low-end models of domestic brands and low-end models of foreign brands.

In fact, the panels produced by the same panel factory and the same production line are also divided into 369 grades, which is why we often hear sales say that their screens are A+. This leads to a question: If Sharp's worst screen is better than Chi Mei's best screen, which one is better? This problem is a bit like Tian Ji horse racing, but from another aspect, it shows that consumers don't need to care too much about the origin of the panel, but should pay more attention to the actual effect of TV.

Regarding the use of panels, I think it is necessary to remind netizens that some manufacturers may use different screens for the same model, such as replacing Samsung screens with Taiwan Province screens. This practice has been very common in the past two years, but it is not without resistance from consumers. When buying, netizens should also pay attention to whether this model has been "changed".
All-in-one machine without set-top box?
There are three kinds of broadcast TV signals in China: one is wireless analog TV signals, the other is cable digital TV signals, and the third is terrestrial high-definition digital TV signals. Wireless analog TV signals are the earliest, and can be received by fishbone antenna. However, because the effect can not meet the demand of high-definition TV pictures, analog signals are being eliminated, which is more common in rural areas and remote mountainous areas.
Cable digital TV signals are signals of local operators, such as Guangzhou Cable and Guangdong Cable. A major feature of this signal is that it requires a set-top box and a decryption card (commonly known as a small card), and users need to pay with the card. Cable digital TV signals are divided into high-definition cable TV signals and standard-definition cable TV signals, which need to be used together with high-definition set-top boxes and standard-definition set-top boxes respectively. The former has the resolution of 1080i, while the latter has the standard of 480p.
Guowei vision card (that is, CAM card, commonly known as calories)
Terrestrial high-definition digital TV signals transmit high-definition signals through wireless live broadcast, and the signal clarity standard reaches 1080i. But the biggest disadvantage of this signal at present is that there are few broadcast cities, only a few sets of high-definition programs. Before the Beijing Olympic Games in 2008, eight cities in China broadcasted terrestrial HDTV signals, but in the last two years, they didn't hear more broadcast information. Moreover, in the original eight cities, such as Guangzhou, not all the cities could receive them, and they were also affected by factors such as floor and orientation.
There are two kinds of digital TV all-in-one machines. One is the all-in-one terrestrial digital TV represented by Toshiba, which can receive terrestrial high-definition digital TV signals through external antennas. The advantage is that it is easy to use and free of charge. Disadvantages are that there are few cities, unstable signals and few high-definition programs (generally only two or three sets of programs such as CCTV HD, CCTV 1 HD).

Second, the cable digital TV integrated machine represented by LG/ Skyworth (also known as the machine-card separation integrated machine) integrates the set-top box function into the TV, and directly inputs cable TV signals (including high-definition standard definition) into the TV through the CAM card (commonly known as the big card) and the decryption card (namely the small card), which can directly bypass the function of the set-top box, so that users do not have to worry about how to place the set-top box.
Set-top boxes affect a huge interest game: it is too early to withdraw from the market.
For the machine card separator, there are two points to pay attention to. First, the decryption cards in each city are different, so different CAM cards are needed. For example, there are Guangdong Cable and Guangzhou Cable in Guangzhou, and the CAM card is different. Second, cable operators (such as Guangzhou Cable or Guangdong Cable) generally sell decryption cards and set-top boxes together and will not sell them separately. Therefore, although the cable digital TV integrated machine saves the area of the set-top box, it does not save the money to buy the set-top box.
Summary: The above six questions are only part of many misunderstandings in TV purchase. If I want to buy a satisfactory TV, I think I should do more homework and know some necessary basic knowledge, otherwise I will only be fooled by the salesman when I get to the store, and I may not be able to buy the TV I need in the end.
