New design - transformed into paintings Television has always been nothing more than a "screen and a box" in people's impressions. In recent years, with the advancement of screen technology and craftsmanship, television manufacturers have begun to sculpt their appearance. Want to be able to catch the eye of consumers in the first impression, the author summed up, the more conventional gameplay is "thin" and "no border", and then forced to a bit, is the art line that Samsung took this year .
Thin: not thinnest, only thinner Since the advent of flat-panel TVs, "thin" has always been the constant pursuit of the television industry in appearance, but different degrees of radicalization in different eras. This year's CES, almost every brand of television can not do without this. One of the most amazing still is LG.

No border: it's really suffocating 
In fact, careful observation will find that the borderless TV is only covered with a glass panel on the front of the fuselage, but not the full screen without borders in the true sense, black edges still exist, a bit similar to the ID on the phone without borders, but still have to admit This effect is indeed more amazing than the metal frame.
In addition to the thickness of the fuselage and the use of knives on the frame, it is estimated that the only thing that can continue to be carved is the pedestal. The most eye-catching or Samsung QLED TV, in addition to the conventional metal base, the Samsung QLED TV also provides users with a more art style base style. 
Some people may want to say that the most important thing for television is the screen. What is the use of so many tricks in appearance? In a word: the television with similar quality, will you pick the one that is more ugly? Any manufacturer wants its products to be perfect, and appearance is the first impression that determines the acceptance of products by consumers. Of course, it is important. The ultra-thin, non-rimmed, and artistic pedestal can at least attract us to pay attention and the purpose is achieved.
New picture quality - closer to the real world picture performance Samsung QLED TV: 100% color reproduction Samsung has been brewing for many years in the display of quantum dots, from investing in German Nanosys to acquiring QD Vision in the United States, each step in the quantum dot study The most leading company. The QLED TV launched at CES uses a new quantum dot material, which effectively improves the luminous efficiency. One of the biggest features of quantum dots is that when they are subjected to light and electrical stimuli, colored light can be produced, and the size of quantum dots can also be controlled. By changing the size of the quantum dot, the wavelength of the light emission can be easily changed, resulting in a rich color. 
Sony 4K HDR OLED: Top Panel + Top Image Processing Sony's action on TV in six months was breathtaking. In August last year, the company launched the Z9D “Messless Full†flagship TV that has not met for many years. CES Sony introduced the second OLED TV after a lapse of ten years. The top panel + the top image processing can not help but sigh that the TV kings who have been and are returning. Since the second half of last year, the trend of quality and high-end consumption in China has become increasingly apparent. Sony’s high-end TVs have also achieved initial success in China. Presumably, the strategy of high-end products will continue to be maintained in the future.

TCL Quantum Dots / Skyworth OLED: Domestically Can Also "Black Technology" 
The new trend - QLED and OLED compete for the highlands, minimalist style has been popular for more than a decade, the television industry has experienced the CRT and LCD disputes, LCD and PDP disputes, and now the situation of QLED and OLED rivaling the Central Plains is even more significant. It is undeniable that OLED has a lot of inherent advantages, but it is also a hot potato, the problem of organic light-emitting life expectancy and yield has been plagued with this new technology. With the improvement of key technologies and compromises, OLEDs have also shown a trend of overwhelming, but at this time another rival QLED (quantum dot) display technology has been staring at it. 
In fact, for most ordinary consumers, the appearance of choosing a TV has far exceeded the evaluation factors of picture quality performance. Have interviewed several sales staff in Guangzhou appliance stores, most consumers choose to watch TV is not enough thin enough, not easy to wall, how material work. Obviously, television has become a kind of home decoration art. To be tacky, relatives and friends come to the house, and a TV with a sense of design can make the owner even more. 
Main effect:
Maximum power point tracking: MPPT Solar Controller can accurately calculate the maximum power output point of the solar panel by monitoring the voltage and current of the solar panel in real-time and according to the characteristics of the solar panel. It then adjusts the panel's output voltage and current to keep it operating at its maximum power output point, maximizing the solar panel's energy conversion efficiency.
High energy utilization rate: MPPT Solar Controller's maximum power point tracking function can ensure that the solar panel is always operating in the best working condition, making full use of solar energy, thereby improving the energy utilization rate of the photovoltaic power generation system.

Overall, the main role of the MPPT Solar Controller is to achieve maximum power point tracking, improve the energy conversion efficiency of the solar panel, and protect the battery from overcharge and over-discharge damage. Compared with other charge controllers, it has unique advantages in energy utilization efficiency and maximum power point tracking and is suitable for applications in solar power generation systems.
The main force of CES2017 has undoubtedly become home appliances, and each core product of the exhibition focused on home appliances has become television. QLED TV in the largest exhibition area of ​​Samsung Pavilion, Sony, LG, Panasonic's most dazzling OLED TV. Why is the halo of television so dazzling? From the author's point of view, display technology has become the most important competitive element in the era of "size and screen" of the Internet. The screen that displays both the content and the TV as the window is maximized. It naturally becomes the best display technology for manufacturers. Carrier. For example, Samsung has applied curved surface QLED technology to its own monitor. LG has also targeted OLED displays for notebooks. The use of OLED technology on small screens is even more numerous. In addition, with the continuous improvement of the quality of family consumption entertainment, more comprehensive functions are no longer the criteria for good product value judgment. They are integrated with homes, and they are better viewed, better used, and more fun. This has made great changes in television design and consumer experience in television and home appliances. Let's briefly summarize the exciting TV products at CES2017. Interestingly, although domestic TV makers such as Skyworth and TCL have all participated in CES this year, the limelight seems to have been robbed by several Internet TV brands such as Microwhales, LeTV, and Xiaomi. Both the Microwhale and LeSco use the Corning Iris glass light guide plate instead of the traditional plastic light guide plate. The TV body thickness is 4.9mm and 6.9mm. It is worth mentioning that the new micro whale television is the third ultra-thin, the thinnest at the body is only 4.9mm, the body is only 25mm at the thickest point, only 28mm away from the wall, the whole visual effect is very eye-catching. However, the most artistic atmosphere is the Samsung “Fresco†TV Lifestyle TV, which directly designs the TV as a picture frame. Nobody can easily identify that this is a TV, which is quite high. So Samsung QLED TV's technological innovation in quantum dot luminous efficiency brought two most intuitive picture quality upgrades. The first brightness surge, the peak brightness can reach 1500 to 2000 nits. The second color gamut is higher and can accurately represent the DCI-P3 color space. Of course, these two changes in image quality are complementary, and more light is transmitted from the quantum dots, effectively increasing the amount of color (officially speaking, the 100% color quantity is restored), so that the picture is maintained at a level of color stability. Richer, it also gives HDR technology a better foundation. What kind of perception experience does this kind of technology bring? The objects in our real life all have their own specific textures, and the colors and textures are different under different lighting conditions. For example, a leaf can present different colors from yellow-green to blue-green in the early morning to dusk. The Samsung QLED TV can clearly and accurately describe the changes of all the colors, showing the texture of the object and its high brightness. The next will not be reduced. The launch of Sony A1E series televisions, in addition to the high gamut and high contrast of the OLED panel we know, there are two killer technologies. Acoustic Surface, the screen also sounds. Many years ago, Sony had such an idea to realize the unity of TV audio and video until it met the mature OLED technology. The secret to achieving the sound of the screen lies in the components on the back of the TV that are similar to the exciter, complete the electro-magnetic-force conversion, and generate the driving force to drive the OLED panel to sound. Because OLED's flexible features can withstand very subtle high-speed vibrations, it is easier to shape the role of a vibrating plate. However, how to solve the problems of timbre, sound intensity, and frequency response uniformity is what Sony engineers are most proud of. Place. Of course, Sony engineers are not willing to disclose too much on this point. It may not be conservative to say that the screen speaker technology has brought a revolutionary solution to the sound. First of all, in terms of appearance, it fits well with the minimalist design concept of the Sony TV slice of Living. The design of the plate is better integrated with the furniture. In terms of sound quality, on the one hand, it solves the problem of ultra-thin TVs that "pronounce sound." On the other hand, the silver screen speaker technology has a wider and flatter frequency response than conventional sound. However, this technology is not perfect, because the screen speaker technology uses wave-like vibration, so the amount of air it can push is limited, so the low-frequency energy will be slightly insufficient. Fortunately, Sony A1E TV back bracket built-in bass unit, and similar to the design of the cloth to make better sound penetration. The second killer, the advanced version of the 4K HDR image processing chip X1, can bring clearer details to the TV, and the latitude of the movie screen has been greatly improved. This is the image that Sony has been focusing on R&D since 15 years ago. Processing technology. Sony's image processing engine is so powerful. The most important point is that it has mastered the entire field of technology from content shooting, production, screening, and distribution. What kind of screen has what kind of performance, well known. Therefore, compared to other manufacturers also claim 4K HDR technology, Sony clearly has a huge advantage. Both 4K UHD Blu-ray and PlayStation 4 games have greatly extended the application extension of HDR TV. In the field of film production and game development, precision image processing plays an increasingly crucial role in improving the quality of the picture. Undoubtedly the oldest brother of OLED TV, W7 OLED series "wallpaper TV" concept once again refreshed our eyes. In addition to the LG OLED's revolutionary pixel dimming control technology, this TV is the world’s first Dolby Atmos-enabled TV and offers unlimited contrast and over one billion color displays. You can use the rich and multi-level complex audio to give the audience a stronger sense of immersion. Domestically produced TV brands have also demonstrated their skills at this CES show. The most representative ones are TCL and Skyworth. The XESS flagship new X2, X3 brought by TCL, and the world's first LED package QD technology concept products, X2, X3 have achieved an amazing 110% NTSC color gamut coverage. In addition, Skyworth and BOE and Hass introduced the pure Chinese-made OLED TV M1 at the CES show, and exhibited a number of "black technologies" such as AR TV, Android TV, Cast TV, and smart home showroom. . Although the two technologies theoretically have a revolutionary display effect, at this stage, they are still only products with cost and technology checks and balances. Like the Sony XEL-1 this lonesome product probably will not appear in the consumer class. However, after the CES, we found that the situation between the two camps of QLED and OLED seems to be tilting, Sony and Panasonic's color TV also joined the OLED camp, mobile wearable devices, small-size panels rely more and more on OLED, It seems that the entire industry chain is advancing towards OLED. QLEDs are much more mature than OLEDs, so they bring cost advantages and market advantages. However, once the OLED technology further improves the cost is low enough, it does not rule out the existing QLED manufacturers to re-team. A small phenomenon is enough to illustrate this point. Samsung has stepped up its efforts to switch LCD panel production lines to overweight OLED panels. So instead of competing between QLEDs and OLEDs, it is better to say that it is competition between market shares among vendors. The market share is not necessarily the best technology, but the most balanced product and deepest routine. Therefore, more and more brand manufacturers pursue the minimalist design of products, pursue the perfect integration of products and space, and emphasize the unity of vision. There is also a "picture frame" television that is designed simply as a piece of art. The TV of the future may be TV when you think about it. Usually it is just a window or a painting. It is not just appearance art and quality technology. TV is still a service-oriented product. In the coming era of artificial intelligence, it will certainly be given more intelligent and interconnected attributes as a "big window" of big data.
In 2016, LG launched the Signature G6 OLED TV with an incredible panel thickness of 2.57mm, which is only estimated to be achieved with OLED screens. But this time, what attracts the most attention is not the upgraded version of the G6, but the W series "Wallpaper TV" W7. Its split design, body thickness is only 2.57mm, it should be noted that no longer as the previous TV manufacturers to promote the thinnest at 2.57mm, but the entire body thickness is only 2.57mm. W7 does not have a pedestal and supports wall hanging. The actual effect is very shocking, such as mural hanging on the wall.
Sony OLED TV A1E
Sony finally returned to the OLED camp in 2017 and launched the new OLED TV BRAVIA A1E series. The design style is also different from last year's Z9D and 9300D. The A1E uses a double-glazed glass design. The back of the camera is also made of glass and has a visual sense of depth. In the bracket used a similar photo frame bracket shape, but also integrated circuit boards, cables and other parts, so that the thickness of the screen body can be maintained even more extreme, although not as shocking as LG W7, but Sony's slice of Living minimalist The design concept is also more attractive. Samsung QLED TV
In addition to ultra-thin, the concept of borderless is more and more common on smart TVs. Samsung's latest QLED TV continued last year's flagship style, 360 no dead ends, no border surface is still one of the biggest highlights of the fuselage. For curved TV, Samsung has always paid attention to the user's visual experience, and the design without borders has greatly reduced the interference on the screen and made the immersion of the curved TV more powerful. Le TV without borders
Faraday’s car has made LeTV one of the focuses of CES, and LeTV has also brought a stunning TV product with the world’s first frameless split TV U65. All-glass body design style, but also make the U65 look unique, non-rimed screen visual effects are very shocking, while the use of split design, body thickness is only 6.9mm. Millet's world premiere of the 4th TV has also embarked on a borderless road. It seems that this year, no border will become a popular design language. Samsung QLED TV Studio Stand and Gravity Stand Bracket
In the past, TVs were slightly rigid at the base designers, and Samsung’s idea was to make TV an artwork for the living room. So with the easel Studio Stand stent, so that Samsung QLED TV become a large electronic album in general, is definitely the most beautiful landscape of the living room. At the same time, there is also a Gravity Stand that resembles a sculptural art piece that supports a certain angle of turn. Sony OLED TV A1E
Sony's photo frame bracket is also one of the highlights. Among the many new television products on display at CES, only the OLED TV A1E adopts this design style, and the LCD TVs adopt the same base as previous generations. Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
