As a TV enthusiast, I always wanted to write an instructional guide on TV, but I had no time. I would like to use this time to buy some topics and write about some personal experiences and understanding of TV. Let you value your friends when choosing a TV.
Proposal 1: Pay more attention to the picture quality of the TV and pay less attention to the functionIt seems that from 11 years onwards, network functions have entered televisions, and 12-year-old smart TVs have become popular. Under the propaganda of manufacturers, many people think that smart TVs will be the future trend, and TVs will not be eliminated sooner or later without intelligent functions. It's true that this is true, but what exactly is it that we promote the elimination of vendors or manufacturers? In other words, what is the core value of the television?
I thought it was picture quality and it was 2D picture quality. This is the core function of the TV and it is also the key to the cost of the TV. The essential function of the TV is to watch the player of the audio-visual program. In the case that the playback effect is kept at a level, other functions have to be discussed. Usb playback supports a full range of formats (though this is a bit of use), network features are perfect, and there are many smart features, which are not worth mentioning. What's more, the so-called smart function nowadays is nothing more than loading an Android chip that is less than 200 yuan. It supports multiple playback formats with only a few decoding functions (the cost does not exceed 100 yuan). I go to TB to buy A 299 HD player, the effect is much better than these do not know the so-called TV comes with features.
However, the improvement of the picture quality is at the cost of the cost. Consumers may not necessarily feel it, and the change of the smart function is real to consumers. For example, a friend comes to visit a guest at home and plays an angry bird on the TV, or to enjoy some pictures on 1024. Well, it's very powerful! ! It is much easier than watching a Blu-ray movie to introduce its own picture quality. The smart function is equipped to show off the sharp weapon:) Don’t you see even the stubborn sony, sharp, Panasonic put down their gestures to do smart TV, and domestic TV is even less Give Yu Li’s recommendation intelligence so that he can completely avoid the disadvantages of his picture quality.
Take the millet TV as an example:
Instead of using millet TV as a TV, it would be more appropriate to consider him as a full-dimming ipad of a larger size. The price of this size is quite good. The premise is that quality can be bought, and what is the quality of the TV should not be expected. According to the standard of traditional TVs, except for screen brands, Xiaomi TV has no relationship with the parameters of the TV. What Qualcomm Snapdragon 600 quad-core 1.7GHz, 2GB memory / 8GB flash memory. 11 key minimalist remote control, subversive interactive mode. WiFi dual-band, Bluetooth 4.0. Depth-custom MIUI TV version, typical tablet parameters, and TV parameters have no half-dollar relationship
Therefore, for those friends who are pursuing a little bit of quality, don't care about what network, smart features, buy a TV with good picture quality and high-definition player, which is definitely more useful than any smart function. You need to know that 2D picture quality reflects TV The cost of the machine, not the additional intelligence.
There may be students to ask, why not say 3D picture quality. First of all, 3D image quality is actually 2D image quality, and 3D image quality is 2D.
The composition of the picture; Second, I insist that the current 3D viewing mode is "anti-human", and the degree of tasteless is far greater than the intelligent function. 60-inch 3D to look within 2m before it feels, and the time is longer, the eyes are uncomfortable, I do not even mention that the landlord is a sad reminder of the spectacles party. Only waiting for the future holographic naked eye 3D, when we come to talk about 3D picture quality
Recommendation II: flat-panel TVs speak better than the brandPeople often ask me if the XX brand television is better, and there are many "masters" who come up and say that the XX brand is good. The XX brand is no longer acceptable. In fact, the development of flat-panel TVs, in addition to Pioneer this cargo is always high-end goods (not the domestic pioneer of that ah), other joint venture brands have high-end and low-end, so when it comes to television is good and bad, according to It depends on the specific model, but it cannot be said that certain brands are better than certain brands. Of course, on the whole, the quality of the joint venture brand is definitely better than the domestic brand.
Speak more (actually Xiaobian request otherwise he will not allow me to pass ) It is really embarrassing to mention Pioneer. In 2008, I went to the Shanghai Baiyidian home appliance counter to watch the TV and saw that the Sony X300a series was shocked by heaven. I saw Panasonic plasma pz880a think that sony was so, to the vanguard of the counter, only to know that other are clouds, etc. To the price suddenly scared urine
In the foreign evaluation of the finest quality LCD sharp elite series, in fact, is the sharp screen plus Pioneer's chip (in fact, the light of the sharp borrower), cnet rating score for the PRO-70X5FD quality is full marks, and cost is a sad reminder 4 points, interested can see this link: Sharp Elite PRO-70X5FD. Unfortunately, TVs are now fast-moving consumer goods. Pioneers have long disappeared in China. Don't mention domestic pioneers. This is a technology that does not have a pioneer half a cent! ! ! ! Pioneer sold the brand to Suning and did not know Gome. Similarly, Philips, Sanyo (looks like this product has never been flat before in the country), the vast majority of Toshiba (tcl brand) are selling themselves.
Once each brand has its own characteristics, for example, sony has always been dominant in the history of chip optimization and dynamic performance, Panasonic high-end plasma and small size LCD ever invincible in the world (Pioneer removed!), Samsung LCD highlight high contrast to please the eyes before Plasma cost-effective, sharp high-end machine is delicate but the black position is deep but the chip is dragging its hind legs. lg has a large viewing angle and fast response time, but the light leakage control is not forceful. The Toshiba chip optimizes the world second. As the television continues to shrink and homogenize, the quality of the TV is more dependent on the shrinkage of each model and the manufacturer's conscience.
Similarly, unlike the display's pursuit of the ips panel (I don't know why, hopefully someone is wondering), the TV panel brand is far less important than everyone thinks, and the cost is the key to the decision panel. For example, Sony 12 years 65hx950 LED LCD TV with a Taiwan screen, compared with the Sony 55HX950 LED LCD TV with Samsung screen picture quality is no less, is far better than 13 years also uses the Samsung panel Sony 55w950 LED LCD TV. The ips panel lg, 12 years ago did not see its outstanding performance in the television market. Similarly, the so-called sharp Kameyama screen, in addition to the panel provided to Sony's professional monitor down to 65rx1 and 65xs1a, other panels are not particularly superior place (by the way, tell everyone that sharp high-end ASV three-color panel The cost and quality are much better than the current four-color panel). The only thing that needs attention is the panel brand. When the same model is used to replace the panel brand, don't worry if he uses Sharp to switch to Samsung, or if LG turns to Taiwan, it's definitely not as good as the original panel! ! !
PS: The monitor did not like to use the IPS panel to find the industry doubters. The original words were answered as follows: “The notebooks and mobile phones have poor backlight and need high-purity panels. TV is not particularly needed.â€
Recommendation 3: LCD panels are important, but others are also important From the above panel topic, most valued friends are very fancy with the panel, but they are less valued for other aspects. This has an important relationship with the company's publicity, especially sharp, Samsung, lg these manufacturers do their own panels, but also is vigorously promote the importance of the panel. In fact, a good picture quality television, a good panel, backlight, chip circuit is essential. Just like the three major elements of television quality: clarity, dynamics, color, and tri-fold are all very important, we can't just focus on one of them. Of course, for gamers and sports fans, dynamics are the most crucial; for movies and art films, color cannot be forgiven; for love movies, clarity and mosaicing are the most important (Just Well, TV has this feature on that day it is estimated that it can sell madness. ).
1, the panel:
Resolution, this is not much talk about the impact of clarity, has evolved to 4k.
Response time, decided to be dynamic, but unfortunately now are not marked. Good machine is generally grayscale 4ms, color response speed 8ms. It is worth noting that the resolution of the 4k panel is double because of the resolution, even if it is 4ms gray response speed, color response speed is only 16ms.
Screen refresh rate, which is also the decision dynamic, now the good panel is 200hz (true 4x speed), x9000a turned out to be 120hz, unable to Tucao! So x9000a is a great big digital photo frame. . . . . Here I say one more thing, now what the manufacturer's double speed to 800, it seems 16 times faster, similar to the Sony xr800, lg mic800, in fact, are nonsense. The true double speed is now the highest 4x speed, because the panel refresh rate is 200hz, the manufacturer only scans the backlight into it, so there will be 800 such exaggerated data, the so-called xr800 is 4x speed + progressive scan, Xr400 is 4x speed + half screen scanning.
The number of color bits, which influences the transition and level of color, is actually a very important parameter. Before Panasonic plasma machine pz880 to 16bit, xs1a is the highest 12bit LCD TV, the previous high-end LCD are 10bit, are now shrinking to 8bit or even 6bit. I heard that Sony's new x950b is a 10bit panel, hoping to have good color performance (when this article was written, it was reported that x950b is not a full 10bit, 4k only supports 8bit/yuv420. Sony, do not die will not die! ).
Contrast, this needs to work with the backlight. But remember two points, first, do not control what the dynamic contrast, this is false data, the brightness can be increased a little high dynamic contrast, more reference is the ansi full-screen contrast, can be a good machine for 2000 ! Second, if there is a regional light control machine, the ansi contrast of this data will not be cooked number, the reason see the following part of the backlight.
The color filter effect and color gamut (influence of color expression), the former of these two data witnessed the shrinking history of the LCD panel, and the latter witnessed what is called shrinking and opportunism, as I detailed in the second article.
2, backlight:
Under normal circumstances, RGB LED backlight> CCFl backlight> Direct-down wled backlight + zone control light> Side-in wled backlight + zone control light> Common direct-down and side-in wled backlight.
RGBLED is basically a luxury-class machine will have, historically used RGBlED Japanese machine I remember there are several: 1,46qulia005, need to book, the price seems to be more than 100,000, the best color of sony civilian tablet history, The best workmanship; 2, sony70x300a, the price of more than 400,000 monsters, sony's civil synthesis of the strongest machine; 3, sharp65/52xs1a, priced at 12999/99999, the best machine in the history of sharp, I was lucky to engage in a Taiwan, drying single posted here; 4, sony55x4500, the cheapest RGBLED TV, about 50,000 or so. RGBLED is now completely extinct because of its high cost.
Ccfl backlight because the relationship between energy conservation has also been eliminated, in fact, from the spectrum perspective, ccfl backlight color and uniformity better than wled backlight, but energy-saving emission reduction is the current trend. This is why the last few machines in the lcd era are the kings of the end of the picture quality. Even when the lcd has fallen to low-end machines, there are still several LCDs that are still proud of most LCDs, such as the sony little cx520. , sharp ge220, etc., these machines because of the relatively low prices of lcd backlight, but the picture quality is better than the same grade or even a few high-level led chip.
WLED compared with the traditional lcd backlight, one is life, from the original can see 10 years to become able to watch 30 years; the second is high brightness, in fact lcd brightness is fully enough, plasma brightness home is enough, we do not need Xiao Sun; The third is energy saving, in line with current energy conservation and environmental protection requirements. Unfortunately, in the current era of cost savings, the wale backlight quality defects are obvious. The first is that the color gamut is relatively low. Ccfl lamp is generally 72% ~ 92%, led 68% ~ 88%. In 13 years, the quantum wide color gamut of Sony is a bright spot, but the color cast is obvious, and the color transition is not as good as the old and wide color gamut. The second is obvious light leakage and poor performance in dark scenes. Led is actually a small light bulb, in order to save costs and reduce the thickness, most of the led flat panel is equipped with led bulbs on both sides, the so-called side-entry led, with respect to the lamp with the LCD, side-in type led because The brightness is more inhomogeneous, it is very easy to cause the light leakage phenomenon, the scene of the dark part is performed more badly (this is originally one of the big soft ribs of the liquid crystal with respect to the plasma). But to solve this problem is not too difficult, direct led + local control light can alleviate this problem (remember, both are indispensable, even the latter is more important, so cheap direct type is actually not significant) Only spend more money and increase the thickness. At the same time, the number of area backlights is also critical. The same size television 512 partition and 16 partition are two concepts. . . . . . Sony's final 55hx950 seems to be 256 partitions, w900 seems to be only 16 partitions. Side-entry wled backlight area backlight is because the partition can not do more (in fact, do more and useless) so the effect is not good. However, from the evaluation point of view, the regional control light is a large killer for contrast and black level, as long as there is area control light, the black level can be very low, so it can have a high ansi contrast, but it is only measured cattle cross, shadow The details are gone.
3, chips and circuits, etc.:
In fact, these two have been ignored, the chip and circuit can affect almost all the parameters of the TV, the common point is the low-rate chip source optimization (sony, Toshiba's strengths), monosodium glutamate DRC circuit, multiplier insertion technology (to be See clearly whether the analog frame or the black frame is inserted, and the analog frame effect is better than the black frame); the high-end has 10bit or even 12bit color input/output, full-screen anti-aliasing (this is very important to the game player, sony's high-end LCD 10 years ago, Panasonic The high-end plasma before the 10 series has this optimization), the cell processor is used for precise color control (local Toshiba model x1000c); the luxury level has a texture correction circuit (only for the 46qulia005 generation machine, the wega chip is really powerful!) . Sadly, these high-end optimization features have now disappeared.
Speaking of this, everyone knows that TV is not a pure electronics industry like mobile phones and computers. To list these, in fact, let everyone know when to buy a TV, which parameters to know, but some parameters manufacturers do not publish (you do not publish the reason you know), but the key is still announced.
In the end, Xiao Bian asked me to recommend some machines. To say something offensive, the machines on the market this year are basically not as good as the 12-year-old machines. Take the more familiar sony examples and they mainly show:
The direct-type backlight disappeared, and the area controlled light shrink. Sony 55hx950 is 256 partitions (cannot remember, it may be 128), and Sony w900, Sony w950 two series of edge-type backlight, only 32 do not know 16 partitions, Even the x9000 series has no direct backlight.
Sharpness and sharpness are further degraded, especially if you look at cable and 720p, obviously not as sharp and clear as the old model.
The high-end series is rich in color, but it is very difficult to tune, and the so-called wide color gamut is obviously the product of the examination. The actual effect cannot be compared with the old and wide color gamut machines.
The most critical is that the X9000a series did not have the expected excellent (Sony Sony KD-65X9000A LCD TV), side-entry backlight, 120hz panel destined x9000a can only be a high-priced digital photo frame.
So I'm hard to recommend.
Really want to recommend in detail, we can look at this post, this person evaluation I still basically agree.
Tired, first write here, if the response is good, write the second article - what those manufacturers do not tell you
There will be specific: 4k meaning, what exactly is the plasma, a generation is not as true or false, so stay tuned.
