How to connect the LED display? LED display assembly is a complex and tedious process, each link requires engineering and technical personnel to have excellent professional technology, in order to be able to upgrade LED display products to do fine, do fine. Industry insiders all know that led display is made up of many modules, and the module is assembled by many lamp beads. In the process of LED display assembly, the assembly steps are ring by ring, and the rings should be careful, otherwise the effect of LED display will be affected. In order to meet the requirements of large area, high brightness, dynamic display and other applications of LED display, as well as the matching requirements of driver matching with LED. The following LED display manufacturers mainly introduce four kinds of LED display connection forms:
1. LED display screen series assembly mode: led1-n in the general simple series connection mode, end-to-end connection, LED display screen work through the same current. The other is the improved method of 1.1 series connection with bypass.
2. Parallel assembly mode of LED display: one is simple parallel, the other is independent matching parallel. In the simple parallel mode, led1-n is parallel head to tail, and the voltage on each LED is equal. This kind of reliability is not high, but also for this problem to take the form of independent matching parallel, with good driving effect, single LED display protection is complete, when the fault does not affect other work, can match with large differences and so on.
3. LED display cross array assembly: cross array is mainly to improve the reliability of LED display and reduce the failure rate.
4. LED screen hybrid assembly mode: the advantages of parallel connection and series connection proposed by the appeal theory are combined. It also includes two kinds. One is the mixed connection mode of series first and then parallel, and the other is the mixed connection mode of series first and then parallel.
The above four LED display assembly connection methods have their own advantages and disadvantages. The most suitable LED display connection method can be selected according to different applications. Many engineering technicians often ignore this point, resulting in a variety of LED display connection failures, which ultimately affect the product quality and reduce user trust. It can be seen that the assembly of Tuosheng LED display depends on the details!
The advantage of small space LED large screen display system lies in the high degree of system integration. The whole system is controlled and managed by a set of control management software. In addition to image processing system, display unit equipment management and control of various signal display modes, it can also control RGB matrix, video matrix and other related peripherals to achieve high degree of integration and centralized control of multiple systems. The key components of the large screen system — Micro spacing LED display unit, pure hardware multi screen processor and large screen control management software need to adopt the same brand, and all adopt the targeted compatible connection design, so as to ensure the system compatibility and provide reliable security at the same time. Display unit, image controller and control software are the core parts of the whole large screen system. If the products of different manufacturers are integrated, it is likely to cause technical compatibility problems, affect the realization of many important functions, and reduce the reliability and efficiency of the system, It is likely to affect the fault diagnosis and timely supply of spare parts during after-sales maintenance. At the same time, it may not be consistent with the upgrade of the system and reduce the scalability of the system.
