With the micro-spacing LED display was born, micro-spacing LED display by virtue of the real seamless stitching, high cost, superior color reproduction capabilities, near-perfect display, etc., has been more and more applications in Command center hall, control room, conference center and other key occasions. With the micro-pitch LED display pixels continue to narrow the distance, making people watch the distance is further narrowed, in order to achieve a better display, not only requires micro-pitch LED display itself in the image processing and processing technology excellence, Micro-pitch LED display front-end signal image splicing processor also put forward higher requirements.

LED lamp beads as the highest cost of LED display, the largest amount of components, the quality of the LED display plays a leading role in the quality.
Full color LED display is the most critical component of LED lamp beads. There are three reasons:
First, LED is the full color screen machine used in the largest number of key devices, each square meter will use thousands to tens of thousands of LED;
Second, LED is the main decision to determine the performance of the main screen, a direct impact on the audience's evaluation of the display;
Third, LED in the overall cost of the display in the proportion of the largest, ranging from 30% to 70%.
How to identify LED display lamp beads?
One, see solder joints. Formal LED lights with manufacturers of LED lights with the use of SMT chip technology, with solder paste and reflow process production
Second, look at the quality of FPC. FPC is divided into copper and rolled copper two, copper-clad copper foil is protruding, look at the line from the pad and FPC to see the connection
Third, look at the LED light with the surface cleanliness. If the use of SMT production process LED lights, the surface cleanliness is very good, do not see any impurities and stains
