The 2016 Fourth Meeting Of The Twelfth National conference was held respectively on March 3 and 5 in Beijing, a number of television stations made a live TV broadcast and the big size display screens were used for the events, the small pitch led screens provided numerous options because these screens are divided into SMD led screens and COB led screens. Both of the solutions are acceptable for the live broadcast, but what’s the difference? 
　　　　   
       The technical advantages of high-density integration three in one COB small pitch led screen used in radio and TV industry:

1. Wide view angle: because of no constraint from module mask, the view angle can be as large as 175°/175°(H/V) to fulfill the video camera shooting demand from various angles, which the help of studio shooting robot arm it can give the clearest high definition images from any angle. 
2. Matt coating technology and refresh frequency multiplication technology: matt coating technology can make light diffuse reflection on the led screen instead of piercing eyes. It can more efficiently weaken the moire film when eliminating the light reflective on led screen, the staffs won’t get dizziness when you work for long time in front of the screen and the 3000Hz refresh rate can remove the scanning lines on camera shooting.
3. Quiet design: low noise operation state with less than 30DB noisy, it equivalents to the sound of tissues fall to the ground. 
4. Core technology: integrated triple density package technology, build-in eliminate moire film technology, bright color degree point to point identically calibrate technology and refresh frequency multiplication technology are getting better and approaching perfect day by day.

The technical advantages of three in one SMD small pitch led screen used in radio and TV industry:

1. The single lamp bead monomer dispensing technology has accumulated many years of practical experience;
2. It needs pre-film structure to eliminate moire;
3. Small size cabinets can build rounded excessive radian to ensure smooth picture lines;
4. Larger viewing angle and better guarantee for the  recording results; good consistency and higher color gamut coverage;
5. Better weak refective properties to present a more professional studio background  environment;
6. 3840Hz ultra-high refresh rate can make high-quality imaging for the convenient and accurate camera capture;
7. Low reflectivity led panel design can present high quality images under studio lighting.
