Recently, LED display screen storms caused by small-pitch technology continue to strike. From outdoor to indoor, from indoor to high-definition, LED display technology is impacting people's daily life with lightning speed.
Two years ago, when it comes to small-pitch LED displays, people are still stuck in the simple indoor display concept. Today, the constantly updated pitch data is being announced to people: the era of LED high-definition display has arrived! The birth of many new products such as LED super TVs, small-pitch HD screens, and LED advertising machines has also pushed indoor displays to a new level.
LED super TV to grab the indoor market Nowadays, the use of LED display in the outdoor market is very mature. In the face of a more promising indoor market, the LED display is naturally unbiased, and the small-pitch technology has been used to launch the indoor display market. Comprehensive offensive.
With the development of LED display technology, the emergence of LED super TV has broken people's traditional views on LED TV. Televisions that use LEDs as luminescent materials on backlights have long been called LED TVs. The LED Super TV is a TV product that directly uses LED panels. Compared with traditional LCD panels, the LED panel has a wider color gamut, faster response speed, higher contrast ratio and better viewing angle. It represents the future development trend of display technology.
LED super TV is actually an extension concept of high-density small-pitch LED display, which is the result of the gradual improvement of indoor display requirements. Nowadays, high-precision series of LED displays have begun to be applied in more and more professional and commercial indoor display fields, such as indoor high-end monitoring rooms, conference rooms, etc., especially in the high-precision indoor applications of 72 inches or more.
Compared with traditional indoor display products, LCD liquid crystal splicing and DLP splicing, LED display screens have always had the problem of large particles and unclear viewing at close range, and with the breakthrough of technology, 1.2mm or even 1.0mm LED displays are gradually breaking the pattern of traditional indoor product applications.
As we all know, the biggest advantage of indoor high-density small-pitch LED display is that the display is completely seamless and the natural color of the display color. The traditional DLP, LCD and other display technology to improve the limits, can only make the seams shrink, but can not make it disappear, there is a phenomenon that the seam can completely engulf a pixel. The LED display has a large plasticity in splicing by virtue of the seamless splicing. At the same time, in terms of post-maintenance, the LED display has a mature point-by-point correction technology. The display can be used for one-time correction of the whole screen using the display for more than one or two years. The operation process is simple and convenient for later maintenance.
Throughout today's indoor display technology, each has its own limitations and limitations, and it is impossible to simply define which technology has an absolute advantage. As for the small-pitch LED high-definition display, although it has an absolute advantage in display performance and splicing plasticity, its high price may still discourage many buyers. In the future, with the improvement of technology and the reduction of cost, whether small-pitch LED display products can go to a broader civilian market is also a major direction for manufacturers to work hard.
A samarium–cobalt (SmCo) magnet, a type of rare earth magnet, is a strong permanent magnet made of an alloy of samarium and cobalt. Smco is also named with Smco magnetic steel, Smco permanent magnet, Smco permanent magnetic iron and rare-earth cobalt permanent magnet.
It's a kind of material made from raw earth metal samarium and cobalt and produced by after a serial of process burdening, melting, milling, pressing and sintering.It's also a high performance, low temperature coefficient permanent magnet with its high working temperature-350 degree centigrade. When working above 180 degree centigrade, its maximum energy product BH and steady temperature are superior than NdFdB magnetic material. It needn't to be coated because it is difficult to be eroded and oxidized.
Sintered Smco permanent magnetic materials have the character of brittleness, lacking of the ductility. So it isn't suitable for using as structural part when being designed. The physical specifications of Smco(1:5) is better than Smco(2:17)'s because Smco(1:5) is easy to machine while Smco(2:17) is more brittle. Smco permanent magnet magnetized must be picked up carefully during the process of assembling.
Smco magnet is widely used in space probe, national defense and military, microwave appliance, communication, medical equipments, motors,instruments, various magnetism spreading devices, sensors, magnetic processor, magnetic lifter and so on.
