FHD means full HD, which is FULL HD, which is called Full High DefiniTIon. Generally reach the resolution of 1920*1080. FHD means full HD. When your source reaches 1080P resolution, LCD TVs that support FHD resolution output can perform completely.
Generally used in home appliances (flat-panel TV), digital products, notebooks, computers, digital cameras, camcorders, MP5, MP4 and so on. FHD display screens are also commonly used in mobile phones.
In the internationally recognized standards, "HD" is defined as three standard forms of 720p, 1080i and 1080p. Full HD is 1920*1080p. For this standard, there are generally two conditions: the video vertical resolution is more than 720p or 1080i; the video aspect ratio is 16:9. Among them, "P" refers to progressive scanning, and "I" is interlaced scanning. Generally speaking, 480*320 and 640*480 are “standard definitionâ€, 1024*720p and 1920*1080i are “HDâ€, 1920*1080p is “Full HDâ€, and 3840*2160 and 7680*4320 are “Ultra HDâ€.
Another type of video with insufficient resolution to achieve HD (resolution "=1280*720" is SD (Standard DefiniTIon), the standard 4:3 is 640*480 (VGA), and 16:9 is 848*480 (WVGA). , PAL is 720*576, NTSC is 720*480. Of course, there are also "variants", such as 15:9 is 800 * 480 (WVGA).
Many cameras already have the ability to shoot FHD videos. The general movie is made after being processed by FHD. FHD has the following frame rates: 1920*1080 60p(i)(NTSC) 1920*1080 30p(NTSC) 1920*1080 50p(i)(PAL) 1920*1080 25p(PAL) 1920*1080 24p (movie). 60p(i) and 50p(i) are also known as Full HD Progressive.
There is also a 4:3 aspect ratio with resolutions of 1440*1080 and 960*720. The former can also be called Full HD FHD in 4:3, and the latter is HD HD, which is often found in cameras. The news we saw after 2010 is generally not taken at 640*480, but on the two.
Limited to this, the largest FHD format currently available is 1920*1080 60/50p(i). Since the three resolutions of 1920*1080 and 1280*720 and 640*480 are multiplied, that is, (the size of the shot) is 4:2:1, some cameras with high-speed photography can only be 1280*. 720 100fps (PAL) 640*480 200fps (PAL) 1280*720 120fps (NTSC) 640*480 240fps (NTSC).
HD is a video with a resolution or pixel of 1280*720 or higher, and the 2010 cap is 1920*1080. In other words, 16:9 standard HD video has only two resolutions: 1280*720 (HD) and 1920*1080 (FHD). HDTV is a high-definition TV with a resolution of 1280*720 or higher. To view high-definition pictures and videos (resolution = 1280*720) on a high-definition TV (resolution > 1280*720), connect the TV to a computer or camera DVD with an HDMI cable.
IPS screenThe IPS screen is a TFT-based technology, and its essence is still a TFT screen. IPS screen (In-Plane Switching) technology is a liquid crystal panel technology introduced by Hitachi in 2001, commonly known as "Super TFT".
The biggest feature of the IPS panel is that its two poles are on the same surface, unlike the other liquid crystal mode electrodes are arranged on the upper and lower sides. This technology optimizes the arrangement of liquid crystal molecules and adopts a horizontal arrangement. When the external pressure is encountered, the molecular structure is slightly depressed downward, but the overall molecules are also horizontal. When encountering external forces, the hard-wired liquid crystal molecular structure is much more robust and stable than the soft screen! Therefore, the image distortion and the color of the screen are not generated, and the screen effect can be protected to the utmost extent without being damaged. There is also an S-IPS panel that is an improved version of IPS.
The main common hard screen is the IPS screen. The soft screen mainly refers to the VA and CPA screens. The main reason is that the VA screen is the most common. Here I want to make a special point: the ordinary consumer's understanding of the hard screen has a misunderstanding, that the hard screen is to add a layer of hard protective film on the LCD panel, in order to avoid the LCD screen from the external hard object puncture. This is wrong.
Due to the excellent performance of IPS technology, many manufacturers have begun to use hard screens extensively, and vigorously promote IPS hard screen technology to provide consumers with higher definition and performance of LCD TVs. Hard-screen LCD TVs have become mainstream products in the color TV industry. In fact, in the fields of high-tech fields such as aerospace, medical, design, and communication, many experts also use hard-screen LCDs.
Professionals use IPS hard screens, mainly in the advantages of IPS hard screen in terms of dynamic resolution, accurate color reproduction, and viewing angle. First of all, compared with the traditional liquid crystal, the IPS hard screen has a stable liquid crystal molecular arrangement structure, and the response speed is faster, so that it has superior expressiveness in dynamic definition. The hard screen also completely eliminates the blurring and water-grain diffusion phenomenon of the traditional liquid crystal display when it is subjected to external pressure and shaking, and the image sticking and smearing are eliminated when playing the extreme speed picture. Therefore, the moment is in the state of motion. The aerospace, automotive, and subway industries have adopted IPS hard screens to achieve image quality without loss. It is reported that the newly opened Beijing Metro Line 5 and bus car TVs have adopted IPS hard-screen LCD.
The difference between ips screen and fhd screenFHD is an abbreviation for resolution, for example:
FHD=1920*1080 resolution
HD=1280*720 resolution
XGA=1024&TImes;768 resolution
WXGA=1280&TImes;768 resolution
However, most notebooks currently have a resolution of 1366*768. The resolution of FHD is very high. You can click the right mouse button on the desktop to select the screen resolution. See how much support your computer supports.
IPS is a display mode of the screen, which is the hard screen mentioned in the market, and one of the data wide viewing angle technologies (IPS/E-IPS/AFFS/FFS are all hard screen wide viewing angle technology, VA/SVA/HVA/ MVA/PVA are all soft screen wide viewing angle technology), and the mainstream notebook screens on the market are all TN.
A hard screen is a film with a layer of resin attached to it, just like a person wearing glasses. The reason why the IPS hard screen has clear and ultra-stable dynamic display effect depends on its innovative horizontal conversion molecular arrangement, which changes the vertical molecular arrangement of the VA soft screen, thus having a more stable and stable liquid crystal structure. Not in the surface sense, the hard screen is to add a layer of hard protective film on the LCD panel, in order to avoid the LCD screen being damaged by external hard objects.
