What is the current TV market? From CES we can find some clues. According to the Wired Magazine article, ultra-low-cost TVs in China are becoming more and more popular. Samsung, Sony, and LG are fighting back with OLED high-end TVs. Chinese low-cost TVs and high-end TVs are confronting each other.
The full text is as follows:
Play HDR video on 4K OLED TVs, which represent the highest technology of today's TVs. The black grade is very deep, with perfect contrast and beautiful colors. Every frame is charming, like an artwork. 
Compared with LG, Samsung, and Sony TV, China's cheap TV is aimed at different markets and they can gain some share. High-end TVs are getting better and better. Likewise, cheap TVs are getting better and better. Brian Blau, Gartner’s vice president of research, said: “The less-known TV brands may have an impact on the United States. This is entirely possible. Existing brands have the brand advantage and can spend money to advertise in the media. They will not give up easily."
Lowering thresholds Hisense and TCL are rising. Analysts predict that more than half of TVs sold this year will be equipped with 4K panels, and the Consumer Technology Association believes that in the first few years of the HD revolution, 4K TVs have spread faster than HDTV. In recent years, the price of 4K TV has rapidly declined, and the streaming media platform has continuously increased 4K content.
Four years ago, if you wanted to buy a 4K TV, the choice was very narrow and the price was as high as $20,000. Now, buying a TV that can play HDR video is less than 500 US dollars. HDR can make the image more realistic and more colorful. 
When it comes to high-end television, the situation is different. Stephen Baker, industrial analyst and vice president of the NPD Group, said: “TV is generally the largest screen in the home, and it is placed in the most prominent place. Users have always liked to choose a brand that everyone recognizes. Consumers show themselves to others. TV, they hope TV looks great, and they hope that investment is worth buying. Excellent design, excellent technology, excellent picture, this is what they are pursuing... It is still very difficult for Chinese brands to enter this market. ."
Baker also said that compared to cheaper TVs, even with the same functionality and the same picture quality, users are willing to spend more money on selecting well-known brands. Last year, nearly half of the TVs of big brands 60 and 60 feet were priced at less than $1,000. These TVs are not yet high-end models. As for the small 32-inch TVs, consumers are willing to pay 50 US dollars more for Samsung, Vizio and other famous brands of television.
Buying a powerful and cheap TV is wise and there is nothing wrong with it. If you increase some budget, you may get more returns. High-end TVs and cheap TVs are starting to show a confrontation. LG, Samsung and Sony are facing challenges because 4K has begun to accelerate its popularity. Now that cheap TVs can provide good picture quality at very low prices, how can high-end brands make high-priced TVs stand out?
What can I get for buying top TVs?
If you buy a high-quality TV, it's worth the extra money. The first is the screen. Is it only OLED panels that provide great picture quality? No, but OLED does have its advantages. OLED's black color is deeper, each pixel has its own independent lighting element, and the bright pixels can be closely tied to the pure black pixels and the light will not leak. As a result, the television has a high contrast ratio. To make the image beautiful, contrast is crucial. The OLED panel is very thin, with a wide viewing angle and ultra-fast response time. 
Resolution, color gamut, and contrast are the “holy grails†of high-end TVs. Samsung, Sony, and LG have added more advantages to their flagship TVs. Samsung has added “quantum dot†technology to OLED TVs. Quantum dots can use nanocrystals to adjust the color of TVs to make the picture more perfect. It can also expand the angle of view and color range, that is, using a high brightness display, the color will not appear pale. .
Sony introduced Crystal Sound technology developed by LG in the Bravia A1E OLED TV, which completely abandoned the speaker. Four converters are fixed behind the screen and they can vibrate to transmit audio, creating an illusion: it seems that the sound is coming from the screen. Although Sony uses the LG panel, Sony owns the X1 Extreme processor, which allows the image to be sharper, giving more detail and making the colors more beautiful. In the history of television, the picture quality of LG TV has always been the best. In 2017, LG went upstairs and the newly introduced TV brightness increased by 25%. It can display more than 99% of the DCI-P3 color gamut. 
Can high-end TVs become mainstream products?
Regardless of how much money you plan to spend on TV, you are faced with a buyer's market. If you want to buy a superb OLED or LCD TV, you will find that they are better than the past and the price is much lower. If your request is not high, just want to buy a TV to see feature films, you can buy a good product at a very low price. Ultimately, the quality enhancement technology that all high-end TVs have will sink into low-cost TVs. Gartner analyst Bu Luo said: "Every year high-end TV prices will fall, and now high-end TV is undergoing a new round of technological change, it is precisely because of this price will decline."
Each year at the CES show there will be some amazing technology. The 55,000 U.S. headset, no one will bring it to the subway; a cool 3 screen laptop, weighing less than 11 pounds, is indeed eye-catching but will not flow into the homes of ordinary people. Unlike TVs, Dream TV is at your fingertips. A few years ago, Dream TV was very expensive and did not support 4K and HDR. Now TV is better and it costs less than $2,000. The price of OLEDs is very reasonable. It came in time because the next round of television revolution has begun.
Although the sales of cheap TVs exceed OLED TVs, LG still claims that its TVs are very popular in certain areas. In 2016, LG OLED TVs accounted for 21% of the market for TVs that cost more than US$2,000. In the market of more than 3000 US dollars and 3,000 US dollars, OLED TVs accounted for 25% of sales. Now that OLED TVs are becoming more and more competitive, high-end LCD TVs are getting better and better, and low-end LCD TVs are extremely low-priced, and LG wants to march downstream.
Tim Alessi, LG Marketing Director, said: "The purpose of OLED is not just to win prizes, but sales are also the purpose."
