The CES, which leads the world once in a year, officially kicked off in Las Vegas, USA. As a global technology grand event, the progress and development of television technology has always been the focus of attention.
As the beginning of this CES, major domestic and foreign consumer electronics giants have launched their home audio and video entertainment products. What changes will this bring us?
Thin, one of the trends
LCD screen getting closer and closer
Compared to last year, Sony introduced its own screen sound field technology, can achieve the A1 sound and picture, this year's Sony released two television can only be said to be a small upgrade.
The new OLED TV A8F was based on A1 last year, which sacrificed a part of the appearance of the industrial design and compromised the space. Another X9000F series is also a small upgrade of high-end products in Sony LCD TVs. The addition of X-Mo fast motion video motion Clarity technology only enhances the smoothness and sharpness of images of fast moving objects. Sony LCD's flagship Z9 series has so far been absent for two years in the annual update cycle.
Integrated projection with TV cabinet
This can be seen as a microcosm of the development of the entire LCD TV, after experiencing the concept of surface, 4K, quantum dots, HDR, dynamic partition backlight, etc., manufacturers rarely bet on the flagship product on the LCD TV. Or it can be said that, in addition to the immature 8K, the LCD screen has not taken decent products to support the flagship device.
This year, OLEDs are relatively more mature on the large-scale end. The 88-inch 8K OLED screen developed by LG Display broke through the short board of the OLED screen on the high-resolution, large-size panel.
In addition to the steady advancement of OLEDs, MicroLED has also officially emerged on this year's civilian television.
As we all know, the OLED screen cancels the backlight of the LCD screen and a layer of “color screen†structure, so it can make great progress on the screen thickness, light and dark details. The main structure is that a layer of organic material is sandwiched between two glass substrates, and dots on the film can self-regulate light illumination and color.
And MicroLED is to replace this layer of organic material film with a neat array of LED light bulbs, can overcome the current OLED overall brightness problems, short life points of pain, but also can further reduce power consumption, color saturation and enhance the ultra-high Resolution display yield.
The Wall MicroLED TV launched by Samsung is 146 inches. The official said that the product will support a modular design and can be used for multiple screens. Although not revealing more details of the product, Samsung's standing on the opposite side of the OLED, QD TV backlighting, and the strategy of developing the Micro LED have become very clear.
TV format is expected to change
The original home TV was a square box. However, with the maturity of plasma and liquid crystal technology, traditional "big ass" CRT TVs have been eliminated and TV products have been filmed flat in front of people. A new round of television changes is taking place.
Last year, Sony introduced the A1 to make people realize that TV does not need an extra speaker. It can also be used as a vibration source through the screen. In addition, it can give people a sound and picture experience; the release of LG wallpaper TV makes people understand The original TV could be as thick as 2 mm thick like a wallpaper. The Samsung Frame TV made people realize that when the TV is on standby, it can also be used as a decorative frame for oil painting frames.
Similar changes have also been continued this year.
LG introduced a curlable 4K OLED TV this year. The thickness of the TV is only 0.18mm. Once the consumer installs in the living room at home, it can be extended from the base below. When not in use, it can be directly stored in the pedestal so that it does not occupy space.
Flexible TV that can be put away
Hisense introduced a 150-inch laser television to further meet the needs of users for large-size screens. Sony also introduced a short-focus laser projection product for ordinary consumers this year. Unlike Hisense, this product integrates a television and a TV cabinet. In addition to the metal body and wooden rack, the product The exterior design is more concerned with the integration of the interior decoration. In the future, your TV cabinet can be directly used for images. It is no longer necessary to install a bulky screen on the network wall.
Samsung MicroLED TVs support a modular design, which means that you will be able to purchase modules for your own TVs in the future. You no longer have to worry about only a few size restrictions on the appearance.
Artificial intelligence, smart home slowly advance
On the eve of CES this year, both South Korean home appliance giants added AI elements to their home appliances.
LG introduces the ThinQ AI platform so that all home appliances can interact and work together via voice. Samsung puts Bixby on the Galaxy into a full range of home appliances. Through voice control and voiceprint recognition, it can realize personalized service for different users. It can also achieve commonality of all home appliances through voice and multiple large screens. Integrate and work together.
Taking Samsung as an example, whether it is on the TV or the large screen on the refrigerator, the status of the doorway can be observed in real time. It looks like a brand new experience, but in fact, this and a year or two ago, the mobile phone was used as a smart device. The way of home entrance is not much different. It is just a new bottle of old wine.
The so-called home appliances can autonomously learn user habits. According to the failure of the LG live demonstration, this technology is not stable at present and it is far from the market.

Excluding these two Korean companies, far-field speech recognition will become the standard for this year's smart TVs from the perspective of TV products released by TCL and Hisense. Prior to the television's voice recognition, you need to input voice commands to the remote controller.
In general, we have seen the future development goals. However, due to the speed of development of technology and cost considerations, these new products are still some distance away from us.
The road to a big country in the manufacturing of a big country is still far away
Referring to the launch of the previous day's press conference, we were all swept by the new technologies of Korean and Japanese companies, and the news of China Group’s TCL and Hisense’s launch of new products in the North American market appeared to be a bit heavy.
Compared to overseas companies' selection of screen materials and breakthroughs in television formats, the innovations of the two black giants in China can be summed up with formality.
Hisense TV and TCL's new TV releases continue the selection of LCD screens. They all focus on the control of quantum dot backlighting and the adjustment of light and shade levels. However, this is actually the technology that Sony has released about two years ago.
Since last year, we can see a lot of third-party data. The market share of China's TV brands has already reached the top three in certain regions. Domestic panel companies have laid out new production lines such as OLEDs and put them into production.
In fact, in the high-end areas, the Chinese group has little sound. In the high-end sector, overseas groups still have the right to speak. The road for China to upgrade from a big manufacturing country to a great power is still far away.
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
SCSI-3
In 1995, the more high-speed SCSI-3, called ultrasci, was born, and the data transmission rate reached 20MB / s. It increases the synchronous transmission clock frequency to 20MB / s and improves the data transmission rate. If 16 bit wide mode is used, the data transmission rate can be increased to 40MB / s. This version of SCSI uses a 68 pin interface, which is mainly used on hard disks. The typical characteristic of SCSI-3 is that the bus frequency is greatly increased and the signal interference is reduced to enhance its stability.
There are many models of SCSI-3. Ultra (FAST-20) has a transmission frequency of 20MHz, a data bandwidth of 8 bits and a transmission rate of 20MBps
Ultra wide has a transmission frequency of 20MHz, a data bandwidth of 16 bits and a transmission rate of 40mbps
The transmission frequency of ultra 2 is 80 MHz, the data bandwidth is 16 bits, and the transmission rate is 80 Mbps
The transmission frequency of ultra 160 is 80 MHz, the data bandwidth is 16 bits, and the transmission rate is 160 Mbps
The transmission frequency of ultra 320 is 80MHz, the data bandwidth is 16 bits, and the transmission rate is 320mbps
The transmission frequency of ultra 640 is 160MHz, the data bandwidth is 16 bits, and the transmission rate is 640mbps
