The purpose of writing this article is that in view of the immediate double 11, a big wave of television began to be promoted. I want you to understand some of the introductory TV, don't be filled with advertising pits! (The younger brother said a few TVs on hand and said to everyone, "It's not good to say hello.")
Start talking about business (please take a closer look at this table, this table is very important oh)
The following is the point that Messi thinks an excellent low-end TV should achieve.
Principle I will not say more, we can buy 5,000 yuan below the four-color RGBW panel is the industry collectively known as the "fake 4K" panel, the display effect is naturally no better than the traditional three-color RGB, mainly in the color RGB obviously Advantage. (The Korean manufacturers, especially LG, use a lot of 4-color RGBW panels on the low-end 4K. Skyworth has some low-cost TVs that everyone needs to pay attention to)
RGB (True 4K): Generally if the RGB pixel arrangement is used, it will usually be indicated on the promotion page.
RGBW: False 4K, some panels will promote the use of LG RGBW (red, green, blue and white) panels, some may be promoted when South Korea imported LG panels, which is actually what we commonly known as fake 4K panel, the most prominent feature of these products is The same size and price are particularly low, so pay attention when buying. (If you are sure you want to buy a product, please check the official website or related professional evaluation, because some TVs with RGBW panel are not marked on the leaflet.)
Many entry-level TVs have no backlight partitions; the following is a comparison of my real shots (a front-facing non-backlit partition and a backlit partition), and the actual effect is that the backlight partition is significantly better than the non-backlit partition, and the light leakage control is better.
The following is the TCL X1 (2W quantum dot surface, 288 partitions); the front panel is the light leakage contrast of a mid-curved surface with backlight partitions (100 or less). (Obviously, the more partitions, the better the light leakage control, the number of high-end partitions is at least 100+, and the low-end TVs are basically in single digits.)
If you are buying a low-end TV, you have the best feature of backlight partitioning, and you don’t have to worry about it because the light leakage control of the general low-end TV is generally normal.
3, priority color selection color domain (NTSC> 85%)The general color gamut NTSC value is 75%, the mid-range TV can reach 85% or more, and the high-end top OLED or quantum dot can reach 100%-110%. The higher the gamut value, the more common understanding is that the more realistic the color, this value is very important for the color display, I hope everyone pays attention to it.
The following is a comparison of the NTSC 75% of the color gamut of my model, and the comparison of NTSC 85% of the color gamut of my model.
It can be clearly seen that the wide color gamut (NTSC 85% of millet), the color display is obviously better than the TV with cool color gamut (NTSC 75%), and if the color gamut is low, if you only have one TV, it may not be obvious. A contrast gap naturally appears. (The general color gamut value of the TV will appear color cast phenomenon, such as the above pure red, the display will be orange)
4. Importance: MEMC (motion compensation)> HDR (high dynamic range)In the current TV, the 4K concept is over. The MEMC and HDR functions are very hot. Basically every TV will show that the camera supports HDR decoding and then XXX, but not all TVs support MEMC (motion compensation). The principle is not mentioned. The role is to shake the moving object, making the picture smooth.
Use the two pictures I actually made to illustrate the differences between MEMC and none.Cool open a 4K (with MEMC), compared to the smoothness of the screen when switching.
Millet a 4K (does not support MEMC), real state of motion shot.
I do not think I need to say more. Everyone can understand the difference between this MEMC function. The MEMC function is very important. It is best to buy this TV with this function.
Does not support MEMC mainly look at the processing chip problem, the current mainstream MStar 6A928 and 6A938 hardware support MEMC function, rather than the mainstream of a certain section of millet Amlogic processor does not support MEMC, so we must see!
HDR function: the best, but do not look too heavyFirst of all, please yourself Baidu under the "real HDR" TV's price, and then you will find that are basically priced at tens of thousands of goods, support HDR decoding that is the basic quality of the TV chip, you want to get the full effect of HDR, also Need to have a good screen + HDR format video source, (real HDR TV) price is tens of thousands. (Current basic TV supports HDR 10)
HDR can improve the contrast, but the low-end TV brightness and other conditions are limited, and there is no HDR supporting resources, so the effect is not great.
On the other hand, some HDR-enabled TVs may suffer from color distortion or over-optimization when they are optimised. Please look at the real shots below. What do you think Huang Lei's face looks more natural? (You have to say hard that you like the yellow face below, I can't)
Almost every TV will advertise its own products. How rich are the video resources? Actually, there is a built-in APP for iQiyi, or Mango TV and so on. It is not much different from downloading and installing third parties. In terms of current resources, or third-party live broadcast and on-demand software is powerful, the biggest advantage is that there is no advertising! ! (However, third-party on-demand software resources have begun to shrink, TV cats and HDPs are standing still, and they still owe them a VIP)
For the smart TVs that I have used, the real resource highlights come from the free VIP, because ordinary dramas can be found on third-party APPs, and some VIP home-made plays cannot be viewed by third parties. "The descendants of the sun", a VIP hard to find, if the TV gift VIP, or can be purchased at a discount of 5-6, it does have some appeal to our average consumer.
Current TVs are basically ultra-thin side-entry TVs. Compared to the previous direct type, the space is compressed, and the natural sound unit becomes smaller. Some manufacturers use JBL and Harman and other audio giants, such as cool open 50A2 JBL A-class audio; TCL Harman S-class audio and so on. Generally speaking, the sound quality of the TVs with the above two brands will not be too bad. If you do not bring the two brands or other big-name audio, you need to pay attention to slightly. (If the built-in does not meet your needs, external audio)
You can clearly see that millet 3S 55 inch TV, the screen is orthodox RGB, color gamut is also good, but also supports backlight partition, but does not support MEMC, this needs attention, that millet this screen is good, but the dynamic effect Relatively poor, watching football games, racing and other screen fluency will be relatively low. (If you don't watch the game often, Xiaomi is a good screen to meet your usual episode, but if you want better picture quality and sound quality, Xiaomi TV 3 or better for you)
Fan Lie, Kukai 50A2
From the above analysis, we can see that although the cool open uses RGB screens, but the color gamut value is low, and there is no backlight partition technology, so the color and light leakage control is poor, the actual perception is that this screen picture quality in general, but this One of the benefits of TV is support for MEMC, so the dynamic effect is smooth, and watching high-speed sports games or TV fluency is better. (If you often watch the game and watch the homemade drama of iQIYI, the fluency and resources of this TV can satisfy you.)
Getting started without perfect TV depends on which points you are looking for. If you plan to purchase entry-level TV, domestic millet, LeTV, Skyworth, etc. are all available. Sharp and Sony don't recommend buying at low-end, not to mention many reasons.
I think that the most important points for buying TV have already been singled out with you. Other aspects, and so on, will have a new TV experience to share with everyone. Granting people to fish is not as good as giving someone to fish. We can refer to these points that messi gave you to pick a pair of 11 suitable TVs. The level is limited, but also hope to forgive me.
(If you find it useful, please bookmark and like it, love you, how is the effect of the first three televisions?)
