Introduction to Four Connection Forms of Full Color LED Display Screen

A full-color LED display screen is composed of many modules assembled together, and the modules are made up of many light beads. During the assembly process, a slight carelessness, even a small problem, can seriously affect the normal use and performance of the full-color LED display screen.

What are the ways to connect full-color LED display screens? Let’s learn together. Only by understanding these aspects of knowledge can LED full-color displays operate more safely and efficiently.

The cost of a single high-power and high brightness LED package is high, while the power of a single high brightness LED display screen that has entered practical use is very low.

Therefore, it is necessary to arrange and combine multiple LED screens according to requirements, which can meet the requirements of large range, high brightness, dynamic display, color change and other applications, and also meet the matching requirements of the driver that matches the LED.

The following mainly introduces four connection forms of full-color LED display screens:

1、 Overall series connection form: In the general simple series connection method, LED1-n is connected end-to-end, and the current flowing through the LED full-color display screen during operation is equal. Another improvement is the 1.1 series connection method with a bypass.

2、 Overall parallel form: 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 full-color LED display screen, no impact on other work in case of failure, and can match with significant differences.

3、 Hybrid form: a combination of the advantages proposed by parallel and series 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.

4、 Cross array form: The cross array form is mainly proposed to improve the reliability of full-color LED display screens and reduce the failure rate.

In summary, there are various connection methods for full-color LED display screens, and each step does not allow any connection errors. Therefore, it is necessary for engineering and technical personnel to understand that each of the four connection methods has its own advantages and disadvantages.
