First, the main screen, the main screen is the screen at the center of the stage. Most of the time, the main screen is shaped like an approximate square or rectangle. Because of the importance of the content it displays, the pixel density of the main screen is relatively high. The main display screen specifications for the main screen are P4, P5, and P6.
Second, secondary screen, secondary screen is used for the main screen on both sides of the display. Its main purpose is to set off the main screen, so the content it displays is relatively abstract. Therefore, the models it uses are relatively large. Now commonly used specifications are mainly: P7.62, P8, P10, P12 and P16 and other models, and in the process of use, are often used grid-type full-color LED display.
Third, video development screen, it is mainly used in relatively large occasions, such as: large-scale concerts, song and dance concerts and so on. In these occasions, because the venue is relatively large, there are many places where it is impossible to see the characters and effects on the stage. Therefore, one or two large screens are provided on the sides of these venues. Its content is generally live on the stage of the scene, now common specifications and the main screen is similar, P4, P5 and P6 these three specifications of the LED display with more use.
In some KTVs, discos and other entertainment venues will also use some special-shaped stage LED display, the so-called LED special-shaped display is based on the LED display is transformed into a special shape of the LED display, so that the new product is characterized Can better adapt to the overall structure and environment of the building, its size and size can be customized according to requirements, the shape is more fashionable and changeable.
Due to the special use environment of LED stage display, in addition to product quality and specifications, there are also several points to note:
1, the control system processing: It is best to be compatible with a variety of signal source input, such as AV, S-Video, DVI, VGA, YPBPr, HDMI, SDI, DP, etc., can play video, graphics, images and other programs, and Broadcast all kinds of information in real time, synchronized, and clear information;
2. The adjustment of the screen color and brightness should be convenient and quick, and the screen body can be quickly rendered with exquisite and realistic color performance according to need;
3, convenient and quick demolition, loading operations;
4, perfect after-sales service system, including installation, commissioning, warranty, 24-hour technical consulting.
Superabrasives are tools used in precision grinding,precision cutting,precision polishing and precision drilling,like Flexible Diamond Abrasive.Superabrasive materials attach to a wheel,blade and drill to make Superabrasive Grinding Wheels,cutting balde and drilling bit.The reason some abrasives are Superabrasives is due to their extraordinary hardness,unparalleled performance,and longevity.
What are Superabrasives?
Abrasives that belong to the Superabrasive family includes,Industrial diamonds: an industrial diamond is a non-gem quality small diamond that is for abrasives,cutting,and drilling tools.
Cubic boron nitride (CBN): Usually called CBN it is the second hardest cutting tool material after a diamond.
Polycrystalline: Is an abrasive material that has a multiple collection of crystal grain structures with individual orientations
CVD Diamond: These are synthetic diamonds made by a process known as chemical vapor deposition.CVD diamonds grow from a hydrocarbon gas mixture. They are extremely hard,have a high thermal conductivity that is five times that of copper. They also have broadband optical transparency,are chemically inert,and only reach graphitization at very high temperatures.
Nanodiamonds: These tiny diamonds are the product of a controlled explosion. Sometimes called a detonation nanodiamond (DND) or an ultradispersed diamond,as this is how they form.

Advantages of Superabrasives
The advantages of Superabrasive grinding wheels are more than extraordinary hardness,unparalleled performance,and longevity. These three features of Superabrasives are the core of many advantages manufacturers gain by an aggregation of services that normal abrasives simply cannot deliver.
These include:
Less expensive tooling and fixturing costs
More wheels on the spindle,smaller wheels,multiple operations
Less floor space needed for manufacturing
Virtual elimination of wheel wear
Automated CNC machines,less labor intensive operations requiring less training
Consistent surface speed from part to part
Better overall throughput with fewer machines needed
Improved Material Removal Rates,Lower Per Part Abrasive Costs and higher speeds
With Superabrasives,production increased by automated CNC equipment,industries have found one way to compensate for the lack of availability of skilled labor. With fewer machines needed,so is fewer workers. With Superabrasives CNC,automation is more concerned with defining a manufacturing process using machine capabilities and mechanization. There is less concern on operator technique. A properly defined process,combined with automatic loaders make for equipment that is almost running itself.
Industry Outlook
Future growth of the abrasives industries will primarily be in Superabrasives. Currently,research and development of Superabrasives are taking place in the following areas.
Custom designed [hard to grind" materials in an increasing number of industries
Creep or deep feed grinding
High-speed,high-performance grinding of hardened steel
Form grinding,sometimes with electroplating,in high precision,high-removal,and high-surface quality applications
CNC-control of line grinding machines
Other abrasive technology developments with Superabrasives are likely to occur in using CVD for the best bonding of coatings to diamond wheels
