A | 多年来，电视一直是CES最值得关注的领域之一，今年也是如此。 The same technology that may power the next generation of mobile networks has been shown to increase the growth of brain cells in mice, according to a new study from Xian Jiaotong University in Beijing.,Radio waves in the terahertz frequency can transmit data at speeds up to 1 terabit (or 125 gigabytes) per second, it is a prime candidate for the next generation of mobile cell phone networks if it can be proven safe. By contrast, current 5G networks use millimeter waves that top out at 20 gigabits (2.5 gigabytes) per second.,But there may be another use for terahertz radio waves: treatment of neurological disorders like Alzheimer’s disease, autism, and Parkinson’s disease.,Science & Tech'Vicious Cycle' Between Alzheimer's Dementia and Daytime Napping Found by Scientists17 March, 19:05 GMT,The researchers exposed mice neurons in a petri dish to 100-microwatt pulse radiation, ranging from 0.3 terahertz to 3 terahertz. The result was that the exposed neurons grew at a rate of 150% compared to the control group. The length of connections also doubled in three days. Despite the accelerated growth, the brain cells appeared healthy.,The accelerated brain growth was not permanent; it slowed two days after exposure.,However, a 2009 study by the Russian Academy of Sciences showed that prolonged exposure to strong terahertz radiation had an adverse effect, increasing the temperature of brain cells, disturbing their development and causing dehydration of the cells which reduces their size and causes other damage.,But Li Xiaoli, the lead scientist of the new Beijing study, thinks that the negative effects of terahertz radiation could be avoided by limiting the strength and duration of exposure.,“The safety of terahertz radiation protocol is a top concern,” Li said. And while the health concerns of terahertz radiation remain, it could, Li believes, be used to treat neurological disorders.,“Abnormal neuron development and the resulting abnormal neural network structure can lead to the occurrence of various psychiatric and neurological diseases, such as Alzheimer’s disease, autism and Parkinson’s disease,” the study’s authors said.,The authors believe that a lower dose of terahertz radiation could increase the production and the activity of certain proteins responsible for brain cell growth, namely GluA1, GluN1, and SY-38. The researchers theorize that is because they contain hydrogen bonds that constantly vibrate at a frequency that falls in the terahertz range. The radio waves combine with the proteins and cause them to resonate in a “non-linear manner,” according to Li, which could “affect the shape of the proteins, and therefore the structure and function of neurons.”However, because proteins vary significantly from each other, only certain proteins are affected by the terahertz radiation at low frequencies. Li says more investigation is needed to learn how proteins react to different exposure intensities.,The study backs up another done at the Institute of Brain Science at Xian Jiaotong University that was published in June. That study found that terahertz exposure could make young mice more intelligent. There, scientists exposed mice to 90-milliwatt terahertz radiation for 20 minutes a day for three weeks. They observed that the exposed mice had more brain cells and were quicker at escaping mazes. However, for reasons that remain unclear, the same effect was not observed in older mice.。在经历了4K、HDR、OLED、量子点等诸多技术后，电视行业对CES的关注度今年已转变为8K。几乎所有主流电视制造商都在CES 2019上展示他们的8K分辨率电视（尽管8K视频内容现在基本上为零）。就尺寸而言，75英寸显然不足以让电视制造商展示他们的才华。LG带来了88Z9型号的8K OLED电视。三星和索尼在2019年的CES上展示了他们自己的88英寸和98英寸液晶电视。三星的8K量子点电视并不是今年CES上最具吸引力的，但LG的“唯一”4K分辨率和65英寸大小的电视：LG签名OLED电视R（65R9型）。Rollable“LG签名OLED电视R型号R是指Rollable，翻译为”Curly“。

B | 没什么废话。让我们先看两张电影。现在让我们回顾一下整个过程。

C | 当LG签名OLEDTV R关闭时，用户只能看到一个矩形底座和下面的支架，这与传统的方形电视完全无关。开机后，底座顶盖打开，基于柔性OLED面板的屏幕从底座内部缓慢上升。在后支架的帮助下，一台65英寸的4K OLED电视看起来像是一个魔术。整个提升过程大约需要10秒钟。选择关机后，屏幕会“顺服”进入底座，底座顶部的盖板会自动关闭，防止灰尘等异物进入。在过去的几年里，不占用额外空间的电视机屏幕尺寸一直在增加。在提供更令人震惊的视觉体验的同时，巨大的电视机也越来越多地出现在房间里。

D | 为了更好地将电视机集成到家庭环境中，电视制造商也做了许多尝试，例如缩小边界，使电视脚手架更加复杂，使用定制电缆或无线传输来减少插入电视的电线数量。

E | 三星还推出了“图片墙”电视，它像一个物理相框一样挂在墙上。三星的“绘画墙”电视LG签名OLED电视R更进一步。采用压接设计，LG签名OLED电视R屏幕仅在需要时出现，不需要时可完全容纳在底座中，大大减少了电视占用的空间。在不看电视的情况下，LG签名OLEDTV R的底座也可以用作立体声音箱。基地内置扬声器支持杜比全景音响，最大功率100W，进一步提高了利用率。此外，LG签名OLEDTV R只能扩展四分之一的屏幕区域。用户可以使用这个“小屏幕”来控制家用电器和查看音乐列表。LG Signature OLED TV R等消费电子产品的不折不扣的设计经验可以看作是先进的设计创新，必然会带来一些小问题。然而，至少从LG官员提供的信息和国外一些媒体的初步经验来看，LG签名OLEDTV R的可滚动屏幕并没有给这种体验带来太大的危害。

F | 第一个是屏幕卷曲的寿命。

G | 国外媒体TechRadar称，LG的工程师透露，标志性的OLED电视R屏幕可能会被提升并降落5万次。换句话说，如果你一天开关五次（即一天10次），你可以使用它将近14年。LG签名的OLED电视R和其他旗舰电视系列在质量和功能上没有区别。处理器是LG最新的第二代AlphaA9。

H | 接口还使用HDMI 2.1，支持4K 120P视频输入。LG签名OLEDTV R还搭载最新的WebOS 4.5操作系统，支持谷歌助手、亚马逊Alexa和LG的Thinq智能家电平台。有趣的是，在随后的系统升级中，LG签名OLEDTV R也将支持苹果的AirPlay2。LG已经明确表示，65英寸版本的ignature OLED TV R有望在今年下半年正式推出。这部充满“黑色技术”的电视并不是一个令人惊异但遥远的未来计划，而是一个可以立即在市场上看到的大规模生产产品。然而，签名OLED电视R的价格势必很低。LG还没有正式宣布签名OLED电视R的价格。
