LED display multi-clock connection form you know several
It is not easy to assemble the entire Led electronic display, just like configuring an assembled computer, and even the LED display is more complicated to assemble, and there are more steps to pay attention to.
It is connected by a lot of modules, and the modules are assembled by many lamp beads. The steps in this are ring by ring, and the ring must be careful, otherwise the effect of the led display screen will be affected. The important thing about the LED display is in connection. Once the connection is not good, the next step is not good. So today, let's discuss what are the ways to connect the led display? Only if you understand these aspects, the LED display will be safer and better, because it is also related to the high brightness power of the LED display. The cost of a single package of high-power high-brightness LEDs is high, and it is currently put into practical use. The power of a single high-brightness LED display is very small. Therefore, it is necessary to arrange and combine multiple LED display screens according to the requirements. On the one hand, it can meet the requirements of a larger range, higher brightness, dynamic display, color change, and other applications. On the other hand, it can meet the drive of the driver matched with the LED. Match requirements.
1. Overall series form: LED1-n in the simple series connection mode is connected end to end, and the current flowing through the LED display screen is equal. The other is the improved way of 1.1 with bypass connection.
Second, the overall parallel form: one is a simple parallel form, the other is an independently matched parallel form. In the simple parallel connection mode, LED1-n are connected in parallel from end to end, and the voltage on each LED is equal during operation. This reliability is not high, but it also strives to adopt an independent matching parallel form for this problem, which has the characteristics of good driving effect, complete protection of a single LED display, no other work is affected during failure, and it can be matched with large differences.
Third, the form of mixed connection: the advantages of parallel and series proposed by the appeal are comprehensive. It also includes 2 types. One is the serial-parallel-parallel hybrid method, and the other is the serial-parallel-parallel hybrid method.
Fourth, cross array form: The cross array form is mainly proposed to improve the reliability of LED display work and reduce the failure rate.
