HDMI2.0的4K标准数字4:4:4

date:On June 27, 2017 Source:  

   4K言论之说有很多种,一提到HDMI2.0线就知道是4K的标准的连接线了,但如何认清真正的4K,是很多人都不是很了解的,作为一个不是电子发烧友来说,给出的那么一个数字,你就认为它是4K的了,虽然有人却说HDMI2.0的接口不能完美的输出4K/HDR的,后来商家还是否定了这一切的推论,坚信HDMI2.0接口是是完美的支持4K的。

4K speech that there are many, a reference to the HDMI2.0 line to know the standard 4K cable, but how to recognize the real 4K, is a lot of people are not very understanding, as a not an electronic enthusiast , Given a number, you think it is 4K, although some people say that HDMI2.0 interface can not be perfect output 4K / HDR, and later business or denied all this inference, convinced that HDMI2.0 interface is Is the perfect support for 4K.


   其实"4:4:4"、"4:2:2"、"4:2:0"都是一种信号格式/模式,我们经常会看到4:4:4、4:2:2、4:2:0这样的字眼,比如你的5D拍摄的视频是4:2:0取样压缩的,又比如QuickTime的ProRes422格式,或者专业摄影机拍摄时是以4:4:4取样的。

In fact, "4: 4: 4", "4: 2: 2", "4: 2: 0" is a signal format / mode, we often see 4: 4: 4: 2: 2, 4: 2: 0 such words, such as your 5D shooting video is 4: 2: 0 sampling compression, such as QuickTime ProRes422 format, or professional camera shooting is 4: 4: 4 sampling.


   作为一个普通消费者,你是不是看到4色vs3色,就觉得肯定是4色好啊,多一色呢。其实不然,让高清范给你彻底扒一扒3色4k和4色4k的由来,以及厂商们的障眼法。

As an ordinary consumer, you are not to see 4 color vs3 color, it is sure that the 4 color is good, more color it. In fact, let the high-definition range to give you a thorough grasp of a 3-color 4k and 4-color 4k origin, and manufacturers of the eye method.


   过去传统的液晶电视屏幕是通过RGB(红绿蓝)三原色来调和色彩及亮度显示的。每个像素点实际上有3个RGB子像素,3个子像素分别按照信号源的信号控制亮度,就能够调制出一个像素的颜色。4k分辨率(3840x2160)下,一幅画面一共有8.3M(M为百万单位)个像素点,每个像素有三个子像素,总共有24.9M个子像素。

In the past, the traditional LCD TV screen is through RGB (red, green and blue) three primary colors to reconcile the color and brightness display. Each pixel actually has three RGB sub-pixels, three sub-pixels in accordance with the signal signal to control the brightness, it can be modulated out of a pixel color. 4k resolution (3840x2160), a total of 8.3M (M million units) pixels, each pixel has three sub-pixels, a total of 24.9M sub-pixels.


   而4色4k,主要由韩系厂商三星和LG提出的,在RGB基础上加入一个W子像素,就是白色像素,单独控制亮度,这样液晶面板的亮度控制能力更强,透光率更高,细节及对比度表现会更好,而且更节能。

And 4-color 4k, mainly by the Korean manufacturers Samsung and LG proposed in the RGB based on the addition of a W sub-pixel, is the white pixels, a separate control of brightness, so that the brightness of LCD panel control stronger, higher transmittance, Details and contrast performance will be better, and more energy efficient.
