Although the major home appliance sales promotion in the 11 is very strong, but many plan to buy the consumer will still have some concerns when buying TV, such as whether it is suitable for their own, whether to buy expensive, whether it has been fooled by sales. After all, flat-panel TVs are high-priced, long-life products. We should be careful when purchasing. It's not too late. Now we'll go into doubt-free time. >>
How to choose size
Why do we like to go to the cinema to watch movies? In short, it is because the cinema can give us a good “presenceâ€, and the more popular one is a feeling close to reality. Among these, the viewing distance plays a large role. For television, the space conditions are different and the viewing distance is different. So, the bigger the TV size, the better. The important thing is that it matches the viewing distance.
Appropriate size selection for better viewing
The viewing distance mentioned here refers to the distance between the human eye and the TV screen. What size should we choose at home is reasonable? The specific calculation methods are not described here. The viewing distance and TV set under normal circumstances are given below. The size of the relationship between the table, we can see at a glance.
We usually watch TV for a long time, and the proper size can get better viewing effect. If the size deviation is too far, it will cause visual fatigue when we look at it for a long time. Therefore, I suggest that you measure it before you purchase TV. How far away is it to better determine the required size. >>
Select liquid crystal or plasma
At present, flat-panel televisions are mainly classified into LCD TVs (related links: LCD TVs) and plasma TVs (related links: plasma TVs). It is necessary to mention here that LED TVs are actually LED-backlit LCD TVs. Not a new technology. As far as the current situation is concerned, LCD TVs account for most of the market share. Plasma TVs only account for a small part, but can we conclude that LCD is superior to plasma? The answer is no, they have their own advantages and disadvantages.
-------------------------------------------------- ---------------------------
What does LED TV mean?
Although many TV manufacturers have directly advertised their products in the name of “LED TVsâ€, it sounds like a brand new type of TV, but in fact LED TVs are short for "LED backlight LCD TVs," as the name suggests. Still belong to a branch of LCD TV, it is just the CCFL backlight technology used in ordinary LCD TVs, replaced by LED backlight technology. Different from OLED TVs, LED TVs are exactly LED-backlit LCD TVs. Although the abbreviation only differs by one letter, the latter is a technology that is completely different from LCD TVs. It adopts the principle of active light emission and is currently applied in home applications. Not extensive.
-------------------------------------------------- ---------------------------
First of all, to introduce the LCD TV imaging principle, simply speaking, LCD TV is through the current to change the structure of the crystal structure of the thin film transistor on the LCD panel, making it appear.
The basic working principle of LCD TV
Plasma TV uses a display technology using gas discharge. Its working principle is very similar to that of fluorescent lamps. It depends on high voltage to activate the special gas in the imaging unit so that it generates ultraviolet light to excite the phosphorescent substance.
Plasma light display principle
Since LCD TVs currently sell far more than plasma TVs, salespeople on certain stores will give consumers a wrong guide. Irresponsible, they say that plasma is not good for LCDs, and technology is old and is quickly eliminated. , They have their own advantages and disadvantages, below we use the table to understand.
2, dark field dynamic range, rich image hierarchy;
1, the screen size is small, there is no small size model;
2, large size, large weight, high power consumption;
3, due to high-temperature discharge, prone to burning phenomenon.
4, the screen brightness is low, the grainy feeling is more obvious;
5, a larger amount of heat, noise is also more obvious.
Compared with plasma TVs, LCD TVs have the advantages of higher brightness, lower power consumption, longer life, and no burn-in phenomenon. The disadvantage is that the color performance is not strong, and dynamic images have trailing ghost phenomenon. LCD TVs are more suitable for users who do not require high quality TV screens and have a long boot time each day. For example, they are mostly used for watching cable TV and accessing computers. Plasma TVs are more suitable for relatively high demands on TV screens and short boot times per day. Netizens, for example, are mostly users who play PS3/Xbox360/Wii games and watch HD movies. >>
3D TV worth buying
Anyone who knows about the flat panel TV industry knows that in the past 2010, 3D TVs were shining brightly. In 2011, major manufacturers will continue to introduce more 3D TVs. At present, active shutter 3D has been formed. Polarization-type 3D camps, of which the former is priced high, the latter can be less than 5,000. Faced with such a temptation of 3D TV, should not buy it? I believe that many consumers will have this question. To solve this problem, the following describes the type and actual application of 3D TV.
3D TV has a considerable appeal
Realizing 3D stereoscopic images requires two images of the left and right eyes. The images must be completely separated. The left image enters the left eye and the right eye image enters the right eye. The two images must have the correct parallax. There are many specific ways to achieve, currently divided into naked-eye and glasses, and glasses are mainly active shutter, polarized light.
Active Shutter 3D technology is achieved by alternating the images seen by the left and right eyes so that your brain fuses the two images together, resulting in a 3D sense of a single image. The screen will show the picture to the left eye first. At this time, the glasses will cover your right eye at the same time, which is a bit like a pirate's blindfold. Then, the screen will quickly switch to the right eye. At this time, the glasses will turn to cover your left eye and make sure that the picture you see is correct.
Active shutter 3D technology alternates between left and right eye images
The principle of polarization 3D TV is to add a layer of polarization coating on the screen, and the LCD screen outputs two different images in an interlaced manner. Through polarization glasses, the two images are simultaneously entered into the left and right eyes to form a 3D image.
Polarized 3D glasses are lightweight and inexpensive
The advantage of active shutter 3D TV is that the 3D effect is prominent, but the glasses are high in price and the brightness of the screen is low; the polarized 3D TV is excellent in comfort and the glasses are cheap, but the screen resolution is reduced by half, the effect is not active shutter type, and the 3D screen reaches Less than full HD resolution height.
One of the main reasons for the current development of 3D TVs is the 3D source, but in order to allow users to get more 3D experience, many 3D TVs are equipped with 2D to 3D functions, which can convert ordinary 2D pictures to 3D pictures, but are relatively primitive. For 3D, its effect is relatively poor.
2D to 3D screen effect (naked eye view)
As for the price, as more and more manufacturers enter the 3D TV field, the price has been greatly reduced, and unlike the past, only flagship models have 3D capabilities, and many midrange and even lower-end models are now Equipped with 3D features, a 42-inch 3D TV quoted only 3999 yuan, very attractive. If you want to first experience 3D users can consider buying 3D TV, if you do not feel bad about 3D, it is recommended to choose ordinary 2D TV. >>

Is the speed function necessary?
In view of the inherent defects of LCD TVs that are prone to smearing and ghosting, double-speed drive technology has emerged. This is a technology that optimizes the dynamic effects of LCD TVs. It can be divided into frame interpolation technology and backlight scanning technology. 100 Hz is the original technology. Inserting a frame of operation (or a black frame) in two frames, 200 Hz is the insertion of three frames of computation (or one frame of operation + two frames of black) in the original two frames.
Double speed drive 200 technology
Here, we need to make it clear that the domestic cable TV signal is PAL system, ie 50Hz, so 100Hz/200Hz speed is effective, 120Hz/240Hz is ineffective; PS3, XBox and other gaming machines are 60Hz, then 120Hz/240Hz is effective, 100Hz /200Hz is invalid. However, current speed functions such as Sharp and Sony can achieve 50/60 Hz auto-adapting. In the face of these TVs, it only needs to pay attention to several times speed.
As for whether or not it requires double-speed drive, it depends on everyone's needs. Because everyone sees different effects in their eyes, we do not need to deliberately pursue excessive parameters. It is better that consumers use their own eyes to actually experience .
Additional features such as smart TVs
I wonder if you have noticed that many new flat-panel TVs have recently been branded under the banner of “smart TVs.†For example, their smart TV brands can use the Internet to send micro-blogs, video chats, browse web pages with IE browsers, and play somatosensory games. And so on, there are all kinds of extensions.
-------------------------------------------------- ---------------------------
What is a smart TV?
So far, the country has not yet defined a "smart TV" with corresponding specifications. Under normal circumstances, we can understand that "smart TV" is a fully open platform equipped with an operating system that allows users to install and uninstall programs provided by third-party service providers such as software and games. The function is expanded, and a generic term for such a type of television that can be used for surfing the Internet through a network cable and a wireless network is provided.
-------------------------------------------------- ---------------------------
Different consumer groups have different needs for different additional functions. For example, some friends like to watch movies on the Internet. With a smart TV, they can connect to the Internet and enjoy the video directly online. Some friends like to play somatosensory games. Functional smart TV can meet the needs of this part of the user.
Smart TV expansion performance
We can't blindly pursue too many additional functions. After all, some functions are not practical for us, and we don't even use them at all. If we only pursue too much, we only spend more money. The author believes that, according to the current situation, we are still more worthy of attention is still the quality of the effect shown by television, but it is undeniable that intelligence is the development direction of future flat-panel TVs. >>
Bargaining technique big exposure
In order to get higher profits, the merchants often quote very high initial quotes. Therefore, “bargaining†becomes an indispensable part of the purchase process. Only when the two parties achieve a balanced point can they be traded. This is also true for the flat-panel TV market. The price is 8,000 yuan. , it may be purchased for 7,000 yuan.
Appliance stores
First, showing a strong desire to buy
When you meet the bargaining, do not say: "just ask, make a comparison." The correct approach should be to show a strong desire to buy, because sales also want to sell the machine, if he thinks you do not really buy, he will not tell you the true and true price.
Second, ingenious test floor price
To test the reserve price, LCD TVs have higher profits. During the trial price process, if the salesperson can not do the master, then you should ask him to consult the manager or the manager. In general, the manager or manager gives more discounts. In this process, it is necessary to pay attention to insist on don't give gifts and the like, so that the manager gives you a price discount. In this room, after talking about the price, what you have to do is not to pay for it, but to run to another store next door to try again until the price is cut to a minimum. Especially in Gome and Suning, it is imperative to arbitrarily make a counter-offer because the salespersons on both sides actively lower prices in order to retain the guests.
Third, strong insistence on the reserve price
When the sales say "When you add × × yuan to sell to you" do not shake, this shows that the merchant can already accept your price, just trying to let you spend more money. You just go and turn away, or tell him in a determined tone that you won't add it again, which will probably be traded at your original price.
Fourth, bold statement disadvantages
Cantaloupe bittersweet, the world is not the United States, to buy LCD TVs need to consider the factors are nothing more than brand, panel, resolution, speed drive, additional features, interfaces, after-sales service and so on. To buy LCD TVs with too many shortcomings, of course, immediately retreat. If the price is right, and the shortcomings are within the tolerable range, various shortcomings can be used as favorable backing for negotiations. Of course, you have a certain understanding of LCD TVs.
Fifth, price negotiated, grinding gifts
When talking about the price process, we must insist on the situation where the seller will not withdraw. At this time, you must adopt a circuitous tactic. Instead of positively requesting price concessions, you must ask for free TV stands, speakers, and other additional equipment to indirectly win concessions. Once a master "grinding gifts" process is this: say people send headphones ... ... You just said this LCD TV can connect the computer, that line? How to connect the line? ...Yes, LCD TVs can be hung on the wall in addition to the table. Don't you send the stand? Do not lie to me, I heard that you can send ... ... Su Ning over there can be more to disassemble a service, you do not have it? ... I saw this dear friend took the headset, computer cable, bracket, and a free service card.
Edit summary:
In the eleventh festival, many netizens plan to buy flat-screen TVs. However, in the actual purchase process, the phenomenon of being cheated often occurs. It is not difficult to avoid this situation. First, consumers should understand the basics of flat-panel televisions. Buying skills, followed by more than a few shopping malls, to boldly bargain, to clarify the link, I believe we buy to be satisfied is not a difficult task. [Back to Channel Home]
