The LED display is connected by many modules, and the module is assembled by many lamp beads. The steps are one after another, and you must be careful, otherwise the effect of the full-color LED display will be blurred. will have an impact. The most important thing about the full-color LED display is the connection method. Once one connection is not good, the next link will not work properly. Even if it is completed, the flatness, smoothness and clarity of the screen will be greatly affected. The following LED display manufacturers mainly introduce four full-color LED display connection methods:
1. Full-color display box series connection form: in the general simple series connection method, led1-n is connected end to end, and the current flowing through the led display screen is equal when it is working. The other is an improved method with a series connection mode of 1.1 with a bypass.
2. Parallel connection of full-color LED screen cabinets: one is a simple parallel connection, and the other is an independently matched parallel connection. In the simple parallel connection mode, led1-n are connected end to end in parallel, and the voltage on each led is equal during operation. This kind of reliability is not high, but we also strive to take the parallel form of independent matching for this problem, which has the characteristics of good driving effect, complete protection of a single led display, no influence on other work when a fault occurs, and large differences in matching.
3. Mixed connection form of full-color LED display cabinets: the combination of the advantages proposed by the parallel connection and series connection mentioned above also includes two types. One is the hybrid connection method of serial first and then parallel, and the other is the hybrid connection method of parallel first and then serial connection.
4. The cross-array form of the LED full-color display box: the cross-array form is mainly proposed to improve the reliability of the LED display and reduce the failure rate.
