No bends? Take you to read the surface TV consumption pain point

Perhaps the most prosperous period in the television industry in the past two years, LeTV and other new Internet companies flock into the arena, and 4K, surface, HDR and other display technologies have erupted in the short term. After the price war has established 4K television as the main force in the industry, what popular words have appeared in the TV industry in 2016? I believe that surfaces and HDR will be very hot. However, behind the hot, you need to know that the surface simply refers to the appearance of the TV panel, and it does not break through the display technology from a technical perspective.

A few days ago we talked about HDR briefly. We have the topic of the topic in this issue. I want to tell everyone that the curved TV looks really fresh, but some selling points are not as beautiful as you think, or say, playing surfaces. The best effect of TV requires you to know more about its features.


The sensation of being on the spot is not as beautiful as a beautiful woman.

In almost all curved TV introductory pages, the advantage of telepresence is the commonality they talk about. On the spot, the term roughly refers to the screen size and the width of the field of view. The most suitable one is the huge screen in the theater. Some high-end theaters or private theaters use the ring screen to enhance the presence of the movie.

Indeed, I affirmed the sensation of the surfacing of the curved screen, but there is a premise that the curved television can exert its superiority in the presence of the situation when the viewing distance is very suitable. How much should this distance be? Let's think about the cinema scene. When we buy tickets, we always hope to buy the most center or a little bit of the first two rows, because too far away the screen is "small", too close and incomplete. This optimal distance is well understood. It is the distance your eyes can just look at the entire screen. With such a distance, you will get the best presence of a screen.
Curvilinear TV and Flat TV's Presence

In fact, this telepresence is irrelevant to the surface or the plane. Both are just enough to see the full screen distance to maximize the field of vision. Unlike flat-panel TVs, our original intention in buying curved surfaces is to get the best presence. However, some people can get his needs. Some people can't, why?


Look at the "curved surface television" from a distance, because the effect of the distance is almost flat (the image was taken from the Luo Thinking Video column)


Looking at the curved TV at a close distance, the "on-the-spot feeling" has come (images are intercepted from the Luoji Thinking Video column)

The specific principle I may not be able to tell you thoroughly, but we can practice the results. Now, you pick up an A4 paper and bend it a little bit. Then, you should fix the curvature as much as possible and let your arms move forward and backward with A4 paper. You should have the answer. When the paper is close to the eye, both the corners of the curved surface are stronger for the expansion of the field of view or "stereoscopic"; however, when you straighten your arms and keep it away from the field of view, the surface feels less noticeable, or even It is mistakenly thought that it is a flat sheet, which is why the curved surface loses its telepresence characteristics when it is out of the optimal viewing distance.

Before I was evaluating the millet 65-inch curved TV made a practical experience, 1.8 meters viewing distance I can see the whole block screen, I believe that most of the living room can free up this space, right? Even many people's living rooms are higher than this standard. For this reason, I have a little advice on the purchase of curved TVs. In order to get a sense of presence, either the surface TV you buy is large enough, or you move the sofa forward to shorten the viewing distance of the TV, so as not to waste your surface. An extra budget or quality loss on TV.

The surface is beautiful?
The price and quality need you to accommodate

I just spit out the next two points, price and quality. Let's look at the latter first. It is more sensitive.


(Advanced) Side-entry backlight schematic, which spreads the upper and lower LED backlight evenly across the entire TV panel through the light guide

Most flat-panel TVs also use light leakage control as the main topic to improve image quality. Curved TVs need a higher process to control light leakage.

We all know that the LCD panel itself is not an element that can emit light itself, it needs the backlight module to display the image. At this stage, because the price war continues to be hot, LCD TVs use side-entry backlights to save costs. The so-called side-entry backlight is to design the backlight strip on one side of the camera body, and then through a series of components such as a light guide plate and a diffusion film, one side of the backlight is evenly filled into each area of ​​the liquid crystal panel. This requires a very high backlight module manufacturing process, so we see that many low-end TVs cause significant light leakage due to poor backlight design, in essence because the backlight is not spread evenly.

Is it easy to draw a curved TV in this way? Our flat-panel TVs are very difficult to evenly diffuse one or more sets of side backlights to each pixel. It is even more difficult to control the backlight for TVs that need to bend the backlight module. It needs to solve a curved surface. surface". Based on this, it is even more difficult for flat-panel TVs to achieve flat-panel TVs at the same cost (with the exception of self-illuminating OLEDs). This is why current curved-panel TVs of the same size are priced higher than flat-panel TVs, and higher processes can ensure Try to reach the same level of flat-panel TVs.

As for how much the price can be higher? Let's take a look at the surface TV's main brand Samsung's 65-inch TV. According to Jingdong search, the price of its 65-inch entry-level flat-panel LCD TV is 9,100 yuan, and the same entry-level 65 surface it? 11099 yuan, the difference has been as high as 2000, this figure means 20% of the price for the million-dollar TV, accounting for a large proportion.

Of course, not all curved TVs are expensive, such as Cool open T55 OLED curved TV, the official price is 9999 yuan, even lower than most 55-inch OLED flat-panel TVs. Also such as Hisense ULED, TCL's QUHD TV and other products, as the flagship, they have more than 100% color space coverage and hundreds of backlight partitions, and these high-end technologies can only be configured on their flagship TV These flagship TVs have only curved versions, so no choice determines their value.

After the bend, the picture distortion needs to be adapted

Last but not least, you should pay attention to the problem of distortion of the picture on the curved surface television. Especially when you view scenes with lines as the main display content, such as city buildings, you will feel slightly raised on both sides of the middle depression on the curved TV. Deformation of the picture. You may not be able to clearly perceive it from a static screen image, but in my personal experience, the actual brain always wants to convert the surface and screen into a flat-screen TV. This may be my personal reason, but it does allow When I was watching curved TVs, I took a "brain filling" treatment.

Side view curved TV

The viewing position is also closely related to the distortion of the picture. For the curved surface, its recommended viewing angle only appears in front of the TV so that you can feel a very even and symmetrical display from the visual center to both sides. However, when your family is sitting on the side of the TV to watch, the distortion of the picture and the visual difference of the space need to “brain” to the normal viewing effect of the flat-panel TV, which requires a long time of viewing to get used to.

Summary: The above topics related to telepresence, picture quality, price, and viewing angle are general conclusions of people and my personal experience with curved television. I believe that you will revisit the new thing of curved television. For any new form, its birth is more or less different from traditional things, which requires consumers to adapt to the changes that come with it.

When most brands in the TV industry are promoting curved TV, you may mistake it for the mainstream of the future, but before the mainstream becomes mainstream, we really need to polish our eyes and learn more about new things. It does not follow the propaganda materials to perfect it. In the end, when you are ready to accept its strengths and weaknesses, curved television is the right choice for you. â–
