Resolution is one of the hard attributes to measure the quality of display devices and has always been of concern to users. Most of the current display devices are still 1080P, and in recent years the 4K word has frequently appeared in our field of vision. 4K is rapidly gaining momentum with rapid momentum. Japan and the United States will successively open 4K television channels. Does it mean that 4K is about to replace 1080P to dominate the market?
First of all, I believe that many people know or have heard FHD, 4K words, but the concept is a bit vague, the author of the knowledge of the general knowledge of the people, first of all to introduce the "resolution" definition .
Resolution (resolution, RTHK calls it resolution) is the precision of the screen image and refers to the number of pixels that the display screen can display. Since the dots, lines, and surfaces on the screen are all composed of pixels, the more pixels that can be displayed, the finer the picture, and the more information that can be displayed within the same screen area, so the resolution is a very important performance indicator. one. The entire image can be thought of as a large chessboard, and the representation of the resolution is the number of intersections of all warp and weft.
With the increasing market demand of consumers, the high-end display market needs more sophisticated display devices. From the initial 480P CRT TVs to later 720P, 1080P, 2K, 4K, and 8K resolution display devices, the display resolution and the size of the display devices are gradually increasing. 480P, 720P are outdated, the author introduces FHD, 4K in detail for everybody.
FHD: Mainstream resolution
Speaking of FHD Full HD First, we need to understand what are the main HD formats in the market today. This is very helpful for us to understand FHD Full HD next. At present, there are mainly three HD formats on the market: 720P, 1080i, 1080P, etc. Among them, 720P means that the video has a vertical resolution of 720 lines for progressive scanning; 1080i means that the vertical resolution is 1080 lines for interlace scanning; 1080P means that the vertical resolution is 1080 line progressive scan, 1080P format in the three formats the most clear, able to show the most abundant picture details. FHD is an abbreviation of FULL HD (Full High Definition), and some people also call it 1080P, and the actual resolution is 1920x1080 (including 1080i and 1080P).

For Full HD, there is currently no unified logo on the global scale. Generally, all companies design their own symbols in full HD. Currently on the market are commonly used "FHD", "Full HD", "1080p", "Full HD 1080p" and other logos.
FHD is currently the more popular video resolution, like many display devices have already popularized 1920x1080 resolution, there are 15-inch FHD notebook computer monitors, and even 4.6-inch mobile phone display resolution has reached FHD, and flat-panel TVs Not to mention the projector, it has already reached 1920x1080 resolution.
4K: China's FULL HD popularity, Japan and the United States successively opened 4K TV channels
FHD resolution HD format, more exaggerated 4096×2160 is already coming. The 4K concept was originally promoted by the Digital Cinema Initiative (DCI) organization and includes members such as Disney, Twentieth Century Fox, MGM, Sony Entertainment, Universal, Warner Bros. and many other major movie studios. The 4K resolution provides more than 8.8 million pixels for movie-quality images, which is more than four times the current top 1080p. Of course, the price of ultra high-definition is also expensive, the data volume of each frame has reached 50MB, so whether the decoding and playback or editing requires the top configuration of the machine.
The 4K name derives from its lateral resolution of approximately 4,000 pixels (pixels), and the 4K resolutions common in the movie industry include Full Aperture 4K (4096 x 3112), and Academy 4K (3656 x 2664). 4K ultra-high-definition digital movies refer to digital movies with a resolution of 4096×2160, ie 4,000 pixels in the horizontal direction. This is the highest-resolution digital movie at present. 4K is the resolution standard for a new generation of Hollywood blockbusters. It is different from the so-called high-definition television (1080P, 1920×1080 resolution) that we see at home, but also different from the traditional digital cinema 2K resolution large screen (2048×1080 resolution), but with 4096×2160 resolution Ultra-fine picture.
At present, most domestic digital movies are 2K, with a resolution of 2048×1080, and some digital movies are 1.3K (1280×1024), while the so-called rural movies show 0.8K (1024×768). The real 4K movie was shot by a 4K camera and was shown on a 4K projector. Some 4K movies were shot on 35mm film and converted to 4K digital format. Since the resolution of the film film is roughly equal to or slightly better than 4K, the clarity of the movie can be guaranteed after transcription. For mainstream home appliance manufacturers, they are more inclined to make Quad Full HD (3840×2160) devices that are close to 4K, because this resolution standard has a display ratio of 16:9, which is close to the proportion of consumers currently viewing. .
Following the opening of 4K channels by operators such as NTT Plala and JSAT in Japan, SPI International, a well-known pay-TV operator in the world, will also open 4K television channels. TV viewers in the United States have opened 4K ultra-high-definition television channels, and follow-up will also open 4K video channels in Portugal, Spain, the Netherlands, and Mexico.
4K Projection: 4K The most promising area for development is the large-screen display area, and projection is the main force for large-screen displays. Japanese manufacturers with technical advantages have shot their hands. Sony, JVC, and NEC have all turned their sights to the high-end market, while others are directed at major theaters.
Summary of the full text: I believe we have a new understanding of the resolution through the article, the current FHD still dominate the display market. Although 4K products have already entered the market one after another, it has to be said that no content is flawed.
