At the CES 2020 exhibition, which just ended last week, Samsung unveiled a number of new TV products, including the flagship Q950TS QLED 8K rimless TV, the new size micro LED TV "The Wall" and wall-painting TV, etc., demonstrating its strong strength in the field of display technology. In addition, Samsung originally wanted to show a completely wireless TV, but failed to display it because of the venue and other reasons.

Han Jong-hee, president of Samsung Optical display Division, revealed that the wireless TV developed by Samsung does not have a regular video input line, not even a power cord. If it is displayed on the spot, it is difficult to rebuild the walls of the pavilion, and it is too late.

At the same time, Han also pointed out that at present, the farthest wireless power transmission is only about 2 meters, based on the actual situation of the exhibition site, the TV may not be able to light up. For all these reasons, Samsung finally abandoned the display of the wireless TV.

According to the previous patent document, Samsung wireless TV is built in accordance with the principle of electromagnetic induction, and there can be no occlusion within the induction range, and it has not been completely overcome in some technical difficulties. It seems that Samsung will achieve the degree of mass production of wireless TV, there is indeed some distance, at present, their relevant technical personnel are continuing to tackle key problems, we can look forward to next year's CES2021 may be able to see its figure.

 
Haier "tailless TV"

It is worth mentioning that "wireless television" appeared at CES2010 as early as 10 years ago. At that time, the famous domestic appliance brand Haier exhibited the world's first "tailless TV", which realized the wireless transmission of 1080p signal through WHDI wireless video transmission technology, and the principle of "non-radiation magnetic coupling resonance" also realized long-distance efficient wireless power transmission. Although the product realized wireless, but because the technology was not mature enough and the cost was relatively high at that time, it could only be regarded as a conceptual product to show muscle.

Wireless has always been one of the important directions in the development of all kinds of devices, whether it is a TV computer or a mobile phone headset. For example, real wireless headphones, which were very popular last year, have been highly concerned and recognized by consumers, as well as wireless charging, which has been making continuous progress in the past two years, there is a great market demand, so we have reason to believe that the future is the era of wireless.
