Summary of LED module driving methods

"Summary of LED Module Driving Mode" LED module is one of the core components of the large screen. The display effect, consistency, bright color and color difference of the LED module play a decisive factor. When we design the LED module , Usually the way of series connection and parallel connection is used, which way has the least impact on the LED module and the best effect, let's briefly explain it below. What are the main connection modes of LED modules? The following mainly introduces the four connection methods of overall series connection, overall parallel connection, mixed connection and cross array. Overall parallel form: one is a simple parallel form, and the other is an independently matched parallel form.

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 module, does not affect other work when a fault occurs, and can be matched with a large difference. Cross-array form: The cross-array form is mainly proposed to improve the reliability of LED module work and reduce the failure rate.

There are many ways to connect LED modules, and each step does not allow connection errors, so this is something that engineers and technicians must understand. The above four connection methods have their own advantages and disadvantages. After specific analysis of specific problems, finally find It is suitable for connecting LED modules. Many engineers and technicians often ignore this point, which leads to various problems in LED modules, and ultimately makes customers lose confidence in the company. The overall series connection mode: in the general simple series connection mode, LED1-n is connected end to end, and the current flowing through the LED module is equal when it is working.

The other is an improved method with a series connection mode of 1.1 with a bypass. Mixed connection form: The combination of the advantages proposed by the above-mentioned parallel connection and series connection 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.

It is impossible to "become fat with one bite" to build an LED brand. It requires perseverance and a protracted battle. The first thing LED module manufacturers have to do is to determine the brand positioning, and the second is to deeply cultivate the market and do a good job in brand promotion. The prerequisite for the implementation of a strategic brand promotion plan is that the product quality and service can be well received by consumers.

Brand promotion expands the popularity of products and even manufacturers, but it must be the core values ​​such as product quality and service quality that finally lead to the transaction. Product quality is the foundation for the survival of LED module manufacturers, and they must firmly grasp the bottom line of product quality at any time. my country's LED module industry has the characteristics of low threshold, a large number of manufacturers, and fierce market competition. The market is changing, and LED brands are on stage.

Brand building has brought new opportunities to LED module manufacturers, as well as new risks and challenges. Brand is the product of market competition, the survival of the fittest, "the one that remains is king", to a large extent determines the market share of products and even LED module manufacturers, and determines the survival and development of LED module manufacturers. .
