Four types of LED display connection forms:

1. The assembly method of the entire LED display screen in series: In the general simple series connection method, LED1-n is connected end-to-end, and the current flowing through the LED display screen during operation is equal. Another improvement is the 1.1 series connection method with a bypass.

2. LED display screen parallel assembly method: one is a simple parallel form, and the other is an independently matched parallel form. In the simple parallel connection method, LED1-n is connected in parallel at the beginning and end, and the voltage borne by each LED is equal during operation.

This type of reliability is not high, but it has also adopted an independent matching parallel form for this problem, which has the characteristics of good driving effect, complete protection of a single LED display screen, no impact on other work in case of failure, and can match with significant differences.

3. The cross array assembly method of LED display screen: The cross array shape is mainly proposed to improve the reliability of LED display screen operation and reduce the failure rate.

4. The hybrid assembly method of LED display screen: a comprehensive analysis of the advantages proposed by the parallel and series connections mentioned in the appeal Also includes two types. One is the mixed connection method of serial first and then parallel, and the other is the mixed connection method of parallel first and then serial.
