In today's era of rapid development of digital information, LED display screen with its high brightness, high definition, colorful and rich as well as large and small flexible display size and other advantages, widely used in various fields, from commercial advertising, stage performances to traffic instructions, monitoring centers, etc., ubiquitously for us to convey important information, bring shocking visual experience. Behind this, the LED display controller plays a vital role, it is like a behind-the-scenes conductor, precise scheduling of each pixel, so that the colorful picture can be presented perfectly.LCF will introduce the classification and characteristics of the LED display controller in this article.

 (A) according to the control mode classification

1. Synchronized controller

Features: synchronized controller and computer graphics card synchronization, real-time reception of computer output image data. It has the advantages of good display effect, high refresh rate, image without delay, etc., applicable to the display effect of the higher requirements of the occasion, such as stage performances, video surveillance centers and so on. In the stage performance, the synchronization controller can ensure that the display screen and the performance on the stage are perfectly coordinated, presenting wonderful background images and special effects in real time, and bringing an immersive visual experience to the audience.

Working Principle: The computer sends the image data to the synchronization controller through the graphics card, and the controller processes the data and immediately transmits it to the LED display for display. As the data transmission and display are synchronized in real time, the smoothness and accuracy of the image can be guaranteed.

2. Asynchronous controller

Characteristics: asynchronous controller does not need to be connected with the computer in real time, it itself has a storage function, you can pre-store the content that needs to be displayed in the internal memory. Then according to the set time and way to play, with strong independence, easy to use, not subject to computer limitations and other characteristics, suitable for some information release is relatively fixed, do not need to frequently update the content of the place, such as bank business halls, station waiting rooms and other information display. For example, the bank can store interest rate information, business introduction and other contents in the asynchronous controller, and play them automatically and cyclically according to the specified time without manual real-time operation.

Working Principle: The user uploads the content to be displayed to the memory of the asynchronous controller through the network or other means. The program inside the controller reads and processes the data from the memory according to the preset playback order and time interval, and then transmits them to the display for showing. The asynchronous controller can be remotely managed and controlled through the network, which is convenient for users to update and adjust the display content.

 (B) Categorized according to application scenarios

1.Indoor display controller

Characteristics: Indoor LED display usually requires high pixel density to realize clear and detailed image display effect. Therefore, the indoor display controller needs to have higher image processing capability and precision, and can support high resolution image input and output. At the same time, due to the relatively stable indoor environment, the heat dissipation requirements of the controller are relatively low, but the stability and reliability requirements are still very high to ensure uninterrupted operation for a long time. For example, in the shopping mall indoor advertising display, the controller should be able to accurately present a variety of beautiful product advertising images to attract the attention of consumers, and can not fail to affect the normal operation of the mall.

2. Outdoor display controller

Characteristics: outdoor LED display faces more complex environmental conditions, such as direct sunlight, temperature changes, high humidity, dust, etc.. Therefore, the outdoor display controller needs to have stronger environmental adaptability and stability. It usually has a higher brightness adjustment range to adapt to different outdoor lighting conditions; at the same time, it should have good heat dissipation performance and waterproof and dustproof function, to ensure that it can work properly in poor weather conditions. In addition, outdoor display controllers also need to consider factors such as lightning protection to protect the safe operation of the equipment. For example, in the outdoor plaza on the large LED display, the controller should be able to make the picture clearly visible in the daytime glare, and automatically adjust the brightness at night, without affecting the surrounding environment, and can withstand the impact of a variety of natural factors, long-term stable operation.

The above is the LCF editorial to organize the classification and characteristics of the LED display controller, I hope to help you, and welcome you to add or correct.LCF is a collection of R & D, intelligence, sales, operation, service in one of the national specialties and new small giant enterprises, national high-tech enterprises.
