At the CES 2020 show just concluded last week, Samsung released a number of new TV products, including the flagship Q950TS QLED 8K borderless TV, the new size micro LED TV “The Wall” and picture wall TV, etc. Powerful display technology. In addition, in fact, Samsung originally wanted to show a completely wireless TV, but failed to show it due to venue and other reasons.
Han Jong-hee, President of Samsung Optical Display Division, revealed that this wireless TV developed by Samsung not only does not have a conventional video input cable, not even a power cable. It will be difficult to reconstruct and remodel the wall of the exhibition hall if it is displayed on site And time is too late.
At the same time, Han also pointed out that the farthest current wireless power transmission is only about 2 meters. Based on the actual situation at the exhibition site, the TV is likely to fail to light up. For all these reasons, Samsung finally gave up the display of this wireless TV.
According to previous patent documents, Samsung wireless TVs are built in accordance with the principle of electromagnetic induction. There must be no obstruction in the sensing range. Some technical difficulties have not been completely overcome. It seems that Samsung has achieved a level of production of wireless TVs. Distance, currently their related technical staff is continuing to tackle the problem, we can look forward to next year’s CES2021 may see it.
It is worth mentioning that, as early as 10 years ago at the CES2010 show, “Wireless TV” has appeared. The well-known domestic appliance brand Haier exhibited the world’s first “tailless TV” at that time, and realized the wireless transmission of 1080p signals through WHDI wireless video transmission technology. The principle of “non-radiative magnetic coupling resonance” also realized long-range high-efficiency wireless power. transmission. Although the product was wireless, because the technology was not mature enough and the cost was relatively high at that time, it could only be considered a concept product for muscle show.
Whether it is a TV computer or a mobile phone headset, wireless has always been one of the important directions for the development of various devices. For example, the true wireless headset that was very popular last year has received high attention and recognition from consumers, and the wireless charging that has been continuously improving in the past two years has a great market demand, so we have reasons to believe that the future is wireless era.
