Affordable price and high-end configuration have aroused widespread concern of users. However, such a low price can't help but make us have many questions, such as its 4K image quality? Can the shortage of 4K film sources that have been criticized the most before be solved? Also, this time, there are two versions, the art version and the ordinary version, with a price difference of 500 yuan. What was the difference between them before?

With many questions, the author went to the LeTV super tv Experience Hall in the East Fourth Ring Road last week to learn about the new products. As the first LeTV super tv Experience Hall in China, the layout here basically simulates the real living room environment, including sofas, lights and stereos, giving the experiencers the most intuitive home experience. The author once went to the experience hall to test after the release of X60 and S50, but this experience obviously felt that consumers were more concerned and enthusiastic about the products. Although it is not a holiday, consumers who come to personally consult and try TV in just one morning can be said to be in an endless stream, and the small experience hall simply cannot accommodate such an experience. (Friends who want to experience LeTV can go by themselves. Address of Beijing Experience Hall: LeTV TV Experience Hall, floor 1 1 Hongcheng Xintai Building, Yaojiayuan Road, Chaoyang District, Beijing; Experience time: every Monday to Saturday, from 10: 00 am to 12: 00 pm, from 2: 00 pm to 5: 00 pm).

Experience summary: X50 Air, as the first 4K resolution TV launched by LeTV, retains many advantages of the previous products, but at the same time, it has made many improvements in design, especially the ultra-thin body and the unique transparent backplane of the art version, which is impressive and looks more classy at home. In terms of workmanship, although there are still some gaps in technology and details compared with the high-end products of Japan and South Korea, they are already excellent in the same price products.

▲ LeTV X50 Air

Functionally, LeTV X50 Air has brought the latest, largest and most comprehensive 4K resource library with its powerful resource integration capability, making 4K content truly available to users. At the same time, we will continue to develop the carousel platform, which has increased to more than 80 channels. It still has the advantages of no advertisement, quick response and 24-hour uninterrupted broadcast, and has the trend of seizing the users of traditional TV stations. Compared with LeTV UI 3.0, the self-made LeTV UI 3.0 has been enhanced in aesthetics and ease of use. In addition, it has LeTV TV version, China Digital TV, and can install many third-party video applications. It can be said that online video programs are rich in quantity and quality. In addition, functions such as unbuffered playback, multi-screen interaction, game experience, voice control and USB playback are very practical, which are better than most smart TVs on the market.

In terms of selling price, at present, the lowest selling price of Letv X50 Air regular edition is 2,999+980 yuan (the annual fee of Letv TV edition is 2 years), which is equivalent to RMB 3,979. On top of this, 500 yuan is added to the artistic version of Return, which is equivalent to 4,479 yuan. The price is basically equivalent to the lowest price of the same specification 4K TV in China, but considering that LeTV has richer online video resources, stronger configuration and better user experience, it is still worth buying.

What's the difference between different versions? Appearance analysis

The letv super tv X50 Air released this time includes two versions: the art version and the ordinary version. The difference between the two is the price (art version is more than 500 yuan), and then the hardware configuration (appearance: metal transparent plastic back shell; Storage: one is 16G and the other is 8g; Bring your own stereo: Bluetooth and bass). In the Experience Hall, two different versions of X50 Air and S50released before were exhibited, and we can also distinguish their differences more intuitively.

In terms of appearance, X50 Air has not changed much compared with the previous S500, and there is not much difference between the two TVs. It can be seen that both TVs adopt ultra-narrow bezel and silver super-large arc base design, which not only ensures the stability of the fuselage, but also looks more classy. (The curved base is standard on TV, so users don't need to buy it separately. )

▲ Letv S50 (left) vs X50 Air Normal Edition (right)

Letv X50 Air adopts the currently popular ultra-narrow bezel design, and the bezel part has more screws than S50. The advantage of this is to eliminate the redundancy of the traditional secondary wrapping design, save the cost, and be more concise at the same time, but the exposed screws still slightly touched the overall aesthetic feeling.

Due to the LED backlight, the thickness of the whole machine body is well controlled. As can be seen from the following figure, the body thickness of the LeTV X50 Air is only 16.5mm, which is thinner than the Macbook Pro, and it is by far the thinnest 50-inch 4K smart TV in the world.

The back of LeTV X50 Air is a highlight, especially the artistic version of Return, which uses the industry's top-grade polycarbonate transparent backplane (the real machine of the experience hall is the tan backplane). This groundbreaking design allows users to take a glance at the internal power board, backlight driver board, smart board and wiring of the product, which shows LeTV's confidence in the product. At the same time, this TV also has a wall hanging hole to support wall hanging.

Summary: LeTV X50 Air still continues the overall design of the previous S500, but it has been strengthened in the aspects of body thickness, back shell design, detail treatment, etc., adding intelligent remote control and shutter 3D glasses, and the operation experience is better.

Theoretically, pixels per inch have reached the standard of desktop display. As an ordinary TV, there is basically no graininess when playing 4K pictures at a distance of 1 meter.

In order to better show the improvement brought by 4K resolution, we specially put LeTV S50 and X50 Air together for comparison. We play the same picture on two TVs.

Next, when we watch it closely, we can clearly feel the gap between the two TV screens. The resolution of X50 Air is four times that of full HD, and even if we watch it at close range, it can bring shock and vividness beyond imagination.
