CES 2018 Summary: 5 Trends Predict the Future of Television

日期:2018-02-05   类型:Industry information

The 2018 electronic consumption event CES has ended. Greg Tarr wrote an article on HD Guru website summarizing the five TV development trends shown by CES this year.


At this year's International Consumer Electronics Show (CES 2018), people were impressed by the changes in TV contrast performance, image processing and color accuracy.


Each well-known manufacturer has upgraded and expanded its 4K OLED or LED LCD TV product line, added more powerful image processing functions, brought the full array LED backlight back to the LCD TV, and made the TV bigger, brighter, and darker.


At the same time, Samsung released its first home micro LED screen, and some 8K TVs entered the home market faster than expected. We have seen more clearly the future development direction of TV technology.


This year, artificial intelligence (AI) technology has played a core role in the smart home platform of each TV factory. The function of voice commands has reached a new level, from controlling home theaters to ordering pizza on TV screens.


We summarized the five highlights of this year's exhibition and the trends that can be expected in the coming months (years):


1、 TV gets bigger, brighter, darker


Many top TV brands expand the algorithm of brightness, blackness and color limits by adding more powerful processing chips, focusing on video processing, image up conversion and contrast expansion.


Sony


Sony demonstrated the new 4K OLED TV equipped with X1 Extreme processor and the full array backlight LED LCD TV, which can display deeper black field and brighter highlight area on the same screen.


In addition, Sony also showed the next generation X1 Ultimate processor, which has twice the performance of X1 Extreme and can provide peak brightness up to 10000 nits, which is the limit of HDR technology.


Sony's A1E 4K OLED TV provided one of the best image performances of the year in 2017, while the A8F series launched in 2018 will bring more powerful image processing and different equipment installation methods, changing the design of the A1E back bracket to a more traditional vertical installation, and greatly reducing the gap between the TV and the wall in the bracket design last year.

LG


Coincidentally, LG also released the alpha 9 processor built into most 2018 4K OLED TVs (except the entry-level B8 series), and the alpha 7 processor for B1 OLED models and Super UHD LCD TVs.


Alpha 9 improves image processing performance, further reduces noise, and improves the performance of up conversion from lower resolution content to 4K ultra-high definition.


LG Curlable OLED TV


At the same time, LG Display Company demonstrated 65 inch and 88 inch OLED TV prototypes. The 65 inch flexible OLED TV adopts 4K ultra-high definition resolution, which can be rolled into a small box when not in use. The 88 inch screen is an 8K model, which is still far from entering the consumer market. These two TVs are unlikely to go on sale in the past year or two.


Samsung


Samsung also surprised the audience with a 146 inch MicroLED TV called "The Wall" (wall). This is the first time that this kind of display screen has been introduced into the household field. This TV uses the same professional home theater technology as the flat screen TV Samsung is selling. The screen uses OLED like self luminous RGB LEDs as pixels, without backlighting.


But unlike OLED TVs, MicroLEDs can provide extremely bright images without creating image residue. At the same time, MicroLED can achieve the same black field performance as OLED, presenting fine shadow details.


Through the splicing of MicroLED screen modules, the technology can achieve unlimited screen size. Multiple screen modules can be assembled into a large screen, and the joints between modules are almost invisible.


Samsung "The Wall" TV Wall


At present, the size and pixel spacing of MicroLED require a 146 inch screen to achieve full 4K ultra-high definition resolution. However, Samsung said that it is still difficult to develop modules with smaller pixel spacing, so it is unable to reduce the screen size and price to a level more suitable for the consumer market.


Samsung intends to let such products enter the market before the end of the year, but did not disclose the price and delivery date of the 146 inch TV wall. No matter when this product comes into the market, we can imagine that it will be an extremely expensive product, but the improvement of production efficiency will make the price of MicroLED TV drop faster than OLED TV.


In addition, Samsung will continue to push the 4K ultra-high definition LED LCD TV based on QLED technology, and show some models that are full of threats to OLED. These models use full array LED area dimming, which can bring black field, bright highlights and pure bright colors. The flagship product of QLED product line is the 85 inch Q9S with 8K resolution and super peak brightness.


It is reported that the display has thousands of LED dimming zones and uses artificial intelligence technology to generate black fields and peak brightness. The price of this TV has not been announced, and it is estimated to be expensive when it is launched at the end of the year.


In addition, 2018 QLED TVs will not have the same thickness as OLED TVs, but Samsung has still built a full array LED backlight model as thin as 2017 edge lighting QLED TVs.


The full array backlight and area dimming technology also reduce halo artifacts, and expand viewing angle by directly controlling the lighting of LED blocks behind LCD pixels.


2、 Smart TV is becoming more and more intelligent


The biggest trend of CES 2018 may be the arrival of voice controlled artificial intelligence (AI). This technology allows TV viewers to control TV directly in language without using a remote control or smartphone application.


These systems have different trademarks such as LG ThinQ and Samsung's SmartThings platform with integrated Bixby voice control, but each has similar functions, such as adjusting TV volume, finding favorite programs, controlling intelligent thermostats, and so on. Users only need to tell the system what functions they want.


LG ThinQ


Samsung's Bixby voice system was first introduced on Galaxy smartphones and smart refrigerators in 2017, and is currently installed in televisions to control the voice of televisions.


When the SmartThings platform is connected to the home network, the microphone in the TV remote control can be used to receive voice commands and control smart home automation devices compatible with SmartThings.


Similar voice AI technologies are also integrated into TV sets of other brands, usually using Amazon Alexa and Google Home platforms. These platforms require the use of smart speakers with compatible systems to receive voice commands through the always on far-field microphone.


3、 8K TV is getting closer


As mentioned above, a series of TV prototypes displayed by CES 2018 have reached 8K resolution, which also indicates that this market is rapidly growing.


Sharp has released 8K TV, showing the 70 inch TV being produced and sold in Japan for NHK's 8K Super Hi Vision satellite TV transmission.


Sharp also produced an 8K camera worth 90000 dollars, which integrates built-in video recording, real-time playback and image capture functions. The camera and TV are the core of Sharp's 4K/5G strategy.


This spring, Sharp plans to build a 10.5 generation LCD panel and TV assembly plant in the TV Industrial Park in Wisconsin.


LG Display showed an 88 inch 8K OLED TV. Samsung also showed an 85 inch 8K QLED TV that is scheduled to be launched at the end of the year. In addition to using AI for voice control, the TV also uses AI technology to improve the image display quality.


LG 88 "8K OLED TV


At present, native 8K content is still relatively lacking, and all TVs adopt the up conversion technology of super sharp presentation of 4K UHD and full HD content. In addition, these products will also use new image enhancement technologies such as HDR and wide color gamut to make pixels more vivid.


4、 Wireless Broadcasting Enters a New Era


On the occasion of CES 2018, the American Advanced Television System Committee (ATSC) released the core standard of ATSC 3.0, the next generation digital television broadcasting system in the United States. This standard will be gradually extended to the United States in the next few years.


Different from the first ATSC system, ATSC 3.0 is adopted voluntarily. It does not stipulate the timetable for companies to adopt and deploy new standards, nor will it immediately abandon the previous broadcasting platform. In fact, ATSC1.0 and ATSC3.0 platforms will coexist for many years. Therefore, while the new signal is broadcast, the current TV can still receive free wireless TV programs.


The new platform will support the transmission of 4K resolution (8K resolution will also be supported in the future) content, provide advanced emergency early warning system functions, and eventually achieve conditional access, allowing broadcasters to provide high-end pay per view on-demand service or subscription TV content in addition to free wireless TV.


5、 HDR standard selection is becoming clearer


ATSC 3.0 platform will support both mixed logarithmic gamma (HLG) and perceptual quantization (PQ) to transmit HDR content to TV. This means that broadcasters can choose HDR camp freely.


In the live broadcast scenario, HLG HDR will be used more often, because this method does not require the use of special metadata, and is backward compatible with standard dynamic range (SDR) broadcasting, so one signal can be used for both HDR and SDR broadcasting.


The bad news is that HLG does not use post digital dimming, so the quality of HDR images is not as compelling as the PQ based HDR format.


PQ based HDR formats include HDR10, Dolby Vision, HDR10 and Technicolor HDR.


HDR10 is an open benchmark HDR system, and the dimming intensity of the whole movie is consistent from beginning to end. Although this looks good, it may not be as real as those formats that apply dynamic metadata. The dynamic metadata HDR will adjust the picture field by field or even frame by frame to enhance the details and realism.


HDR10 is a format jointly developed by Samsung, 20th Century Fox and Panasonic. It was announced at CES 2018 that it has become an optional HDR format for the ultra-high definition Blu ray standard.


Major companies supporting HDR10


HDR10 is an open and free standard, while Dolby Vision and Technicolor HDR need to pay licensing fees. Technicolor HDR claims that the fees charged to broadcasters and producers are very low, while Dolby Vision is a standard that is neither open nor free.


At CES, Panasonic announced the addition of HDR10, HDR10 and Dolby Vision to TV (for European and Asian markets) and UHD Blu ray players. Other formats may be supported in the future.


Samsung 2017 4K UHD TV will increase support for HDR10 through firmware upgrade, and all 2018 4K models are expected to add HDR10.


P&F USA said it would support Technicolor HDR in 2019 Philips 4K TVs in the United States. Previously, LG also added Technicolor HDR, HLG, HDR10 and Dolby Vision to 2017 4K OLED and Super UHD TVs.


Sony has added support for HDR10, HLG and Dolby Vision in the designated 2017 4K Bravia TV and OLED TV, which will continue in 2018 models. On February 17, Dolby Vision will add a designated 2017 Sony 4K TV through firmware upgrade.
