How to identify the quality of led display quality
Masks, kit problems: the mask of the ink and consistency of the direct impact of the display led display, if the ink is good, led the quality of light, basically shows that there is not much problem.
Control card is basically 99% of the led display manufacturers are outsourced, the industry is better that is the celebration, superstar, de Puda, Nova, Carter these are used in full-color display more Some, relatively stable stability is better.
Led display driver IC: the current development of led display driver is a bit crystal, Mingwei, and some domestic drive IC;
ircuit board: circuit board manufacturers more, Shenzhen is the gathering of electronic products, procurement of raw materials this piece is very fast, the circuit board is divided into two layers and four layers of board, the thickness of two layers is 1.6. , The quality of the circuit board is the internal conductor of the circuit board, the thickness of the conductor to reach the standard thickness to 1ns or more, because the use of the display in the process of temperature rise and lower, if the conductor thin easy The use of the process of fusing, this will cause a large area of quality problems.
The thickness of the box of metal: the box is done with the manufacturers to do the structure of the drawings are related to the structure of the cabinet, the installation is easy, easy to install, the other heat will be better.
