FHD screen
FHD means Full High Definition, or FULLHD, full name FullHighDefiniTIon. generally can reach the resolution of 1920 * 1080. fHD means Full HD, when your source reaches 1080P definition, LCD TV sets that support FHD resolution output can complete the performance.
It is generally used in home appliances (flat panel TV), digital products, notebooks, computers, digital cameras, camcorders, MP5, MP4, etc. Cell phones also commonly use FHD display screens.
In the internationally accepted standards, “HD” is defined as 720p, 1080i and 1080p. For this standard, there are two conditions: the vertical resolution of the video exceeds 720p or 1080i; the aspect ratio of the video is 16:9, where “P” refers to progressive scan and “I” is interlaced. . Generally speaking, 480320, 640480 is “SD”, 1024720p, 19201080i is “HD”, 19201080p is “Full HD “, 38402160, 7680*4320 is “Ultra HD”.
Another kind of video that is not clear enough to reach HD (resolution “= 1280720) is SD (StandardDefiniTIon), generally standard 4:3 is 640480 (VGA), 16:9 is 848480 (WVGA), PAL is 720576, NTSC is 720480. of course there are also “variants”, such as 15:9 is 800480 (WVGA).
Many cameras already have the ability to shoot FHD video. Generally movies are shot in FHD and then processed to make them. FHD has the following frame rates: 1920108060p(i) (NTSC) 1920108030p (NTSC) 1920108050p(i) (PAL) 1920108025p (PAL) 1920*108024p (movies). 60p(i) and 50p (i) also known as FullHDProgressive.
There is also a 4:3 screen ratio, the resolution of 1440 * 1080 and 960 * 720, the former can also be called 4:3 in Full HD FHD, the latter for HD HD, this often appear in the camera. after 2010 we see the news, generally not 640 * 480 shot, but the last two shot.
Limited to this, the current size of the largest FHD format is 1920 * 108060/50p (i). As 1920 * 1080 and 1280 * 720 and 640 * 480 these three resolutions are multiplied relationship, that is (shot out of the capacity size) 4:2: 1, so some cameras with high-speed photography function can only be up to 1280 * 720100fps (PAL) 640 * 480200fps (PAL) 1280 * 72020fps ( NTSC) 640*480240fps (NTSC).
HD is the resolution or pixels is 1280 * 720 or more video, 2010 capped at 1920 * 1080. that is, 16:9 standard HD video only two resolutions: 1280 * 720 (HD), 1920 * 1080 (FHD). hdtv is 1280 * 720 or more resolution of high-definition television. To view high definition pictures and videos (resolution = 1280720) on an HDTV (resolution = 1280720), connect the TV to a computer or camera DVD and other devices with an HDMI connection cable.
IPS screen
IPS screen is a technology based on TFT, in essence, or TFT screen. IPS screen (In-PlaneSwitching, plane conversion) technology is a liquid crystal panel technology launched by Hitachi in 2001, commonly known as “SuperTFT”.
IPS panel’s biggest feature is that its two poles are on the same surface, unlike other liquid crystal mode electrodes are in the upper and lower two sides, three-dimensional arrangement. This technology optimizes the arrangement of the liquid crystal molecules, taking a horizontal arrangement, when encountering external pressure, the molecular structure sinks slightly downward, but the overall molecules are still horizontal. When encountering external forces, the solidity and stability of the molecular structure of the hard screen LCD is far superior to that of the soft screen! So will not produce screen distortion and affect the screen color, can maximize the protection of the screen effect is not damaged. In addition there is a S-IPS panel belongs to the improved type of IPS.
Hard screen is mainly common is IPS screen, soft screen is mainly refers to VA, CPA screen, mainly VA screen is the most common. Here I want to make a special note: the average consumer has a misunderstanding of the hard screen, that hard screen is a hard protective film on the LCD panel, in order to avoid poking the LCD screen by external hard objects. This is wrong.
Due to the excellent performance of IPS technology, many manufacturers began to use a large number of hard screens and vigorously promote IPS hard screen technology to provide consumers with higher definition and performance LCD TVs. Hard-screen LCD TVs have become the mainstream products in the color TV industry. In fact, in professional fields with high technology content such as aerospace, medical, design and communication industries, many experts also use hard-screen LCDs.
Professionals use IPS hard screen, mainly in the IPS hard screen in dynamic clarity, accurate color reproduction, viewing angle and other advantages. First of all, compared to the traditional LCD, IPS hard screen has a solid liquid crystal molecular arrangement structure, faster response time, and thus has superb performance in dynamic clarity. Hard screen also completely eliminates the traditional LCD screen in the external pressure and shaking, blurring and water diffusion phenomenon, play the very fast screen to eliminate the residual image and trailing, therefore, for always in motion in the aerospace, automotive, subway and other industries are used IPS hard screen to obtain no loss of picture quality. It is reported that the newly opened Beijing subway line 5 and bus TV on board the use of IPS hard screen LCD.
The difference between ips screen and fhd screen
FHD is short for resolution, e.g.
FHD=1920*1080 resolution
HD=1280*720 resolution
XGA=1024&TImes;768 resolution
WXGA=1280&TImes;768 resolution
But the current resolution of most notebooks are 1366 * 768, FHD resolution is very high-end, you can click the right mouse button on the computer desktop to select the screen resolution, see how high your computer maximum support.
IPS is a display mode of the screen, which is also known as the hard screen, a kind of data wide viewing angle technology (IPS/E-IPS/AFFS/FFS are hard screen wide viewing angle technology, VA/SVA/HVA/MVA/PVA are soft screen wide viewing angle technology), the current market mainstream notebook screen are TN.
Hard screen is the surface attached to a layer of resin film, as people with glasses. IPS hard screen has a clear and super stable dynamic display effect, depending on its innovative horizontal conversion molecular arrangement, changing the VA soft screen vertical molecular arrangement, and thus has a more solid and stable liquid crystal structure. Not in the superficial sense, hard screen is to add a hard protective film on the LCD panel, in order to avoid poking the LCD screen by external hard objects.
