New observation of home appliances: right and wrong

When Sony introduced the first curved TV in 2013, the main advantages of the curved TV were: 1. It can provide a visual experience with a surround. 2. The cambered body makes the TV larger, so there is space for higher-performance speakers that can improve the sound quality of the TV.

In fact, all the brands that launched the curved TV will introduce the "enveloping" feature of curved TV when introducing their own product features.


If the surrounding feeling is determined by the surface of the curved screen from the physical level, then from the visual effect, this feature also created the surface TV can create an "immersive" experience that is difficult for the flat-panel TV to achieve. Do you remember the first time you were watching a movie in an arcade-screen IMAX theater? One of the advantages of curved TV is that it can provide a similar feeling.

In addition, because the curvature of the curved screen is basically consistent with the curvature of the human eyeball, the image is more in line with human retinal focus after the image is projected onto the eyeball, and the visual effect is also more comfortable. At the same time, for the viewer sitting at the center of the screen, the distances from both eyes to the left and right sides of the curved screen are the same. This means that the sharpness of the edge of the curved TV screen is basically the same as the central area of ​​the screen. This view has recently been recognized by some medical workers. Their experimental data show that the fatigue of human eyes after long-term viewing of curved television is smaller than that of flat-screen televisions.

It was also mentioned that curved television is a major innovation in the field of industrial design for traditional TVs: on the basis of the increasingly thinner and narrower borders of traditional flat-panel TVs, the appearance gap between high, medium and low-end products is rapidly disappearing. . The surface TV allows consumers to intuitively produce a differentiated experience from the appearance, more sense of grade, quality.

The disadvantages of curved TV

Just as coins have positive and negative sides, although the advantages of curved television are objective, but some of its shortcomings have also become some people's "nail, flesh thorn."


First of all, the thickness of a curved TV is much larger than that of a normal flat TV. The main reason is that the space occupied by the curved screen becomes larger and the overall feeling is heavier than that of a flat TV. Although the curved surface TV looks more distinctive, but the matching of the home is also more critical, if the mix is ​​not only difficult to reflect the unique appearance, or even affect the overall style of the home. Second, curved TV has a "dimension". This is the point at the center of the screen. When people are numerous, the screen effects seen by people sitting on both sides of the sofa are obviously inferior to those in the central position. In the end, the curved TV needs a certain size to create a “surrounding feeling”. If the size is too small, the visual effect seen by the audience may not be as good as a flat TV. Finally, curved TVs have higher technical requirements for manufacturers. Otherwise, they are more prone to light leakage, screen reflection, and uneven color than flat-panel TVs. They are also susceptible to physical damage during transportation and installation.

Pushers behind corporate attitudes

In fact, for companies, the advantages and disadvantages of curved TVs have long dawned on them. However, due to the company's own business considerations, various companies have different attitudes toward curved television.

In terms of Japanese brands, although Sony was the first company to launch curved TVs, after the 4K version of curved TV was introduced in 2014, Sony did not launch new surface TVs in 2015. Another Japanese TV brand Sharp, which is still active, exhibited a curved TV prototype this year and is expected to start selling it in the middle of this year.


As for Korean companies, Samsung is currently one of the firmest promoters of curved TV. Samsung's curved TV not only has many series and sizes, but also has a balance between high and mid-range. Another South Korean company LG's curved TV line is relatively more focused on OLEDs, and the number of curved LED TVs is relatively small.

For domestic companies, TCL, Hisense, and Changhong have all introduced surface products for the mainstream market, and Konka and Skyworth have not shown signs of surface LED TVs (Skyworth had previously launched a small number of curved OLED TVs). The color TV brands such as Xiaomi, Leshi, Kukai, and KKTV have not launched curved TVs recently.

In fact, behind the emergence of curved TV sets, panel makers may be the thrust that cannot be ignored. In fact, color TV companies such as Hisense and Changhong do not have their own LCD panel production lines. To promote curved TVs, they must obtain support from upstream panel companies.

For panel companies, the revenue from the sales of curved screens at this stage is much greater than that of the industry's highly mature flat LCD products. If you can persuade consumers to buy more curved TVs, it is naturally an excellent business.

For color TV companies, LeTV and Xiaomi’s penetration have led to a significant drop in the average price of products and corporate profits. The curved TV with better profit performance and differentiated features has naturally become the focus of promotion.

But even in the curved TV camp, there are different sounds. For example, LGD, a large panel manufacturer in South Korea, believes that curved LED TVs are prone to light leakage and are not easily designed for thinness. "Compared to the realization of a variety of curvatures, and the realization of the same slim design and the same picture quality of OLED technology as flat-panel TVs is the future direction of curved TVs." South Korea's LG Display OLED Division Minister Lu Xiangde on several occasions When asked about the idea of ​​curved TV, this view was thrown.

Another panel industry veteran who asked not to be named told us that in addition to some inherent disadvantages (in fact, it can also be reduced or even eliminated through various technical means), the biggest problem is that it needs a larger size to reflect Immersive visual experience. According to the current 3 meter viewing distance of Chinese families, only 100-inch products are considered to be excellent, 70-80 products can only be said to have passed, and 50 products are of little value. If these objective conditions are separated from each other, simply revealing each other and even personal attacks are meaningless behaviors. Since the birth of televisions, there has not been a single technology that can achieve only advantages and no defects. The unrestricted debate will ultimately not only make consumers lost, it will even cause consumers to feel distrustful of the entire industry, and it will ultimately damage the company itself.
