4K超高清电视命名HDMI光纤解说

date:On October 25, 2017 Source:  

   HDMI光纤与4K有这么间接的光纤,HDMI光纤拥有4K的分辨率,但是如何知道4K是怎么发展起来的呢。由于4K分辨率电视才出现不久,业界对其命名并没有明文统一,只是在国际电信联盟(简称ITU)2012年5月的一个电视规格推荐草案中,将新的4K(3840×2160)和8K(7680×4320)规格归纳为超高清晰电视(简称UHDTV),因此业内一般将4K电视称为超高清电视,区别于全高清和高清。

HDMI fiber and 4K have such an indirect fiber, HDMI fiber has 4K resolution, but how to know how to develop 4K it? As the 4K resolution TV appeared soon, the industry named its name is not clear, but only in the International Telecommunication Union (ITU) in May 2012 a TV specification recommended draft, the new 4K (3840 × 2160) and 8K (7680 × 4320) specifications summarized as ultra-high-definition television (referred to as UHDTV), so the industry generally 4K TV called ultra-high-definition TV, different from full HD and HD.


HDMI光纤解4K之谜

   虽然4K分辨率相当火热,五大面板制造商也有针对4k分辨率进行开发产品的计划,但是分辨率的改变会影响到很多东西,甚至整个产业链都会随着变化,而按照目前(2012年)情况,4K分辨率无疑还面临着很多阻碍。首先,从技术上看,4K面板面临着技术难题超高清对应的是大屏幕,因此面板厂商计划推出的4K面板将会在55寸以上,而当前(2012年)4K面板所面对的挑战是随着解析度提高,液晶像素点更小,穿透率会下降,这在面板电子或光学上都有所挑战。

Although the 4K resolution is quite hot, the five panel makers also have plans to develop products for 4k resolution, but the change in resolution will affect a lot of things, and even the entire industry chain will change with the current (2012) situation , 4K resolution is undoubtedly facing a lot of obstacles. First of all, from a technical point of view, 4K panel is facing technical problems Super HD corresponds to the big screen, so panel makers plan to launch the 4K panel will be 55 inches above, and the current (2012) 4K panel challenges As the resolution increases, the liquid crystal pixel is smaller and the transmittance drops, which challenges the panel electronically or optically.


   现在面板厂商主要采用金属氧化物制程和非晶硅制程来制造超高清分辨率面板,面板厂商提供的大尺寸液晶面板除极少数采用传统非晶硅技术外,多数采用金属氧化物技术的TFT驱动结构,其更为先进,也更具有技术难度。

Now panel manufacturers are mainly using metal oxide process and amorphous silicon process to manufacture ultra-high resolution resolution panel, panel manufacturers to provide large-size LCD panel with a small number of traditional amorphous silicon technology, the majority of metal oxide technology TFT drive Structure, its more advanced, but also more technical difficulties.
