The full-color LED display is composed of multiple modules, and the components are composed of multiple lamp beads. When assembling, a little carelessness, even a small problem, will seriously affect the normal use of the full-color LED display And performance play.

What is the connection method for the full-color LED display? Let's take a look together. Only when you understand these aspects, the full-color LED display can work more safely and efficiently.

The cost of monolithic packaging of high-power high-brightness LEDs is relatively high, and the power of single-piece high-brightness full-color LED displays that are currently put into practical use is very small.

Therefore, the led screen must be combined according to the required arrangement. On the one hand, it can meet the requirements of a wider range of applications, higher brightness, dynamic display, color change, etc., on the other hand, it can meet the matching of the driving device supporting the led screen. Require.

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

1. Overall series connection: LED1-n are generally used for simple series connection, which are connected end to end. The full-color LED display screen passes current and balances current when it is working. Another improved 1.1-type series connection with bypass connection.

2. Overall parallel connection: one is a simple parallel connection, and the other is an independent parallel connection. LED1-n are connected in parallel end-to-end in a simple parallel mode, and the voltage that each led is subjected to is the same when working on it. This reliability is not high, but it is also argued that an independent matching parallel connection mode is used for this problem. It has the characteristics of good driving effect, complete protection of a single full-color LED display, and does not affect other work in the event of a failure, and has a large difference in compatibility. .

3. Hybrid form: The advantages of the parallel and serial forms mentioned above are combined. There are also two types. One is string first and then parallel, the other is parallel first and then string, both concepts have.

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

In summary, it shows that there are many ways to connect full-color LED displays, and no connection errors are allowed at each step. Therefore, it is necessary for engineers to understand that the above four connection methods have their own advantages and disadvantages. Specific analysis of the problem, and finally found a suitable form for connecting the full-color LED display. Many engineers ignored this point, leading to various problems with full-color LED displays, and ultimately making customers lose confidence in the company. From this, it is found that a small detail often determines success or failure, so the full-color LED display technology must be refined and detailed.
