Led display assembly is a complicated and cumbersome process. Each link requires engineers and technicians to have excellent professional skills to be able to fine-tune the LED display products. The insiders know that the LED display is made up of many modules, and the module is assembled by many lamp beads. In the assembly process of the led display, the assembly step should be followed by a ring, and the ring should be careful, otherwise the effect of the led display will be affected. In order to meet the requirements of large-area, high-brightness, dynamic display and other applications of LED display, and the drive matching requirements of the driver matched with LED. The following mainly introduces four types of led display connections:
1, led display screen series assembly method: generally simple series connection mode of LED1-n, end to end connected, led display working when the current is equal. The other is an improved way of connecting the mode with a bypass of 1.1.
2, led display screen parallel assembly method: one is a simple parallel form, and the other is an independent matching parallel form. The LED1-n in the simple parallel mode is connected in parallel at the beginning and the end, and the voltages on each LED are equal when operating. This kind of reliability is not high, but it also strives to adopt an independent matching parallel form for this problem. It has a good driving effect, a single led display protection is complete, the fault does not affect other work, and the matching can be greatly different.
3, led display cross array assembly method: cross array shape is mainly to improve the reliability of the led display work, reduce the failure rate proposed.
4, led display hybrid assembly method: by the appeal of the parallel and series respectively proposed advantages of the comprehensive. Also includes two. One is a hybrid mode in which the strings are first combined, and the other is a hybrid mode in which the strings are first and then followed by a string.
The above four types of LED display assembly and connection methods have their own advantages and disadvantages, according to different applications, choose the most suitable led display connection. Many engineering and technical people often ignore this point, leading to a variety of connection failures in the LED display, which ultimately affects product quality and reduces user trust. It can be seen that the assembly of the LED display screen determines the success or failure of the details.
