超级大乐透走势图彩票2元网:Confusing LED display Video Resolution
体彩超级大乐透走势图查询 www.fqfacr.com.cn In the high-definition small-pitch LED display Video Resolution to become the mainstream of the market today, we often hear these terms: 1080P, 4K, 8K, etc.,But what does 4K mean? If 4K is four times greater than 1080p, does that mean 4K is 4320p? The above questions we come to answer you one by one.
720P, 1080P, etc., that is, "video pixels of the total number of rows", for example, 720P said video 720 pixels, and 1080P means that a total of 1080 video pixels, 1080P resolution camera usually the number of pixels is 1920 * 1080. "P" itself represents "progressive scan", which is an abbreviation for Progressive, relative to interlaced (Interlaced).
2K, 4K, etc., that is, "the total number of video pixels," such as 4K, said the video has 4000 pixels, specifically 3840 or 4096 columns. 4K resolution of the camera is usually the number of pixels is 3840 * 2160 or 4096 * 2160.
MP is the total number of pixels, that is, the number of pixels (P) and the number of columns (K) multiplied by the results (megapixels). For example, the 1080P camera is 1920 pixels multiplied by 1080 pixels, resulting in 2MP (megapixels) of the total number of pixels.
1080p(or full HD)
Well, TVs, on the other hand, have historically used the vertical to describe resolution (going back to the glass tube days). So 1080p is the vertical resolution. Nearly all HDTVs have an aspect ratio of 1.78:1 (16x9, aka "widescreen"), so that means a horizontal resolution of 1,920 pixels (1,920x1,080).
This is another source of confusion, since decades of TV discussions have talked about vertical resolutions, and then all of a sudden we're talking about "4K TVs," which refers to the horizontal resolution.
That means 1080p is not "1K." It's 2K, as much as UHD TVs are 4K. Which is to say, at 1,920x1,080 they're close to the DCI's 2K specification of 2,048. That said, most people don't call 1080p 2K; they call it 1080p or Full HD.
Roughly half the number of pixels of 1080p.
We begin with a discussion of the top resolution 4K of the current market, so that we can talk about the basic principles to be answered when we answer the overwhelming majority of the resolutions.
Technically, "4K" means a horizontal resolution of 4096 pixels. this is the resolution proposed by the digital cinema advocacy Alliance (Digital Cinema Initiatives). due to the different aspect ratio of the film, the exact shape of the rectangular screen determines the aspect ratio of the film, so its vertical resolution is not specified.
Therefore, strictly technically, 4K is not ultra HD, ultra HD resolution of 3840 x 2160. the difference between the two pixels is only 13%, basically do not see much difference. the vast majority of people prefer the "4K" this name means ultra HD.
8K truth like 4K. If you are talking about the display, then the horizontal and vertical pixels are two times the 4K display: 7680 x 4320. but the number of 8K video source is not much, we are still very far from the 8K into the mainstream, not alone said a brief talk about the Super Hi-Vision standard resolution of 7680 x 4320 pixels, a total of up to 33 million; in order to better support naked-eye 3D display technology, Super Hi-Vision a picture frame rate up to 120fps standard to watch; distance and perspective mode also has increased dramatically.
The picture shows the number of pixels per major resolution format. Of course, this is not the actual size, just a visual representation.
From the biggest to the smallest: 4 k technology, screen height to width ratio of 1.78:1 (black); UHD (white part); 2 k technology, the screen height to width ratio of 1.78:1 (green); Full hd 1080 p (red); 720 p (blue).
Of course, before "4k" becoming very popular, we almost never seen the word "2 k". It often refers to the "standard format". Digital movie projector resolution are used in most theaters for 2 k (some lower the resolution of the projector). Also, according to the DCI, it specifies the horizontal resolution of 2048, only vertical resolution is not specified.
The display resolution
The display resolution:WUXGA、WXGA、WXXXGA、WXCBGBSA and WXLADYGAGA
In the computer world, people use these convoluted, shocking the user friendly letters to describe the resolution of chaos. Oh, that is wrong, not shocked "people", after all they are computers.
Basically, we are most likely to see is FHD (1920 x 1080) and the WUXGA (1920 x 1200). The rest of the few, You can prepare yourself a copy of the memorandum copy down memory. Fortunately, we are only looking for a cheaper projector or computer monitor will meet these letter combinations.
