How to choose the control system of LED display screen?

If LED modules, LED power supply and wires are the hardware basis of LED display playback, then the control system is the corresponding software part, similar to the "driver" of a computer. This article will explain to readers in detail what control systems are available for LED display screens, as well as what should be paid attention to when choosing an LED display screen control system.

First of all, we know that LED display screens are divided into two categories: single (double) color and full color. The corresponding LED display screen control system is also divided into two categories, single (double) color control system and full color control system. In addition, we also need to determine whether the LED display screen is synchronous or asynchronous.

1.Single (dual) color control system
Most of the content played by single and dual color LED display screens is scrolling text files, such as many store frontsdisplay scrolling text, conference logos display scrolling text, etc. The files of this type of content are relatively small.

Most of them are a few K, up to 1-2M, and the required memory is relatively small, so the control system of single and double color LED display screens is mostly asynchronous card. The transmission methods of this control system include serial port, network port, USB port, and the increasingly popular mobile phone WIFI transmission.The most popular single and double color control systems are: AVIC, Huidu, Lingxin, Feikong, Yikuo, Kale, Guangzhou Xinyi, Qingyuan and other manufacturers’ control systems.

Single (double) color LED display control systems generally have a readback function, that is, as long as you open the corresponding software and read back the control card parameters, you can enter different text content in the corresponding editing interface. After editing, click Send to replace the original text content.

2. Full-color control system
The content played by full-color LED display screens is mostly pictures, videos, PPT and other files with relatively large data. According to the playback requirements, we can use either synchronous playback system or asynchronous playback system.

The synchronous playback system is mostly used to play videos and PPTs. Its main function is to display the playback content synchronously with the computer monitor, that is, what is played on the computer is played on the LED display. It is mainly used in conferences, offices, stages, large exhibition halls, etc.

Generally, the computer display settings are set to "copy mode" (or a few multi-screen synchronous playback requires "extended mode"). The more popular brands of synchronous playback systems are as follows: Nova, Linstar, Colorlight, Kaishida, Huidu, AVIC, etc. Among them, Nova and Kaishida have a relatively high market share in stage large-screen applications.

The asynchronous playback system is mostly used to loop notifications, advertisements, promotional pictures, and promotional videos. Its main function is to send the text, pictures, or videos to be played to the asynchronous storage card for loop playback. It is mostly used in small exhibition halls, street advertising screens, door screens, traffic guidance screens, and other scenes.

In recent years, with the advancement of 4G technology, the combination of asynchronous playback system loaded with 4G modules has also been very popular in application scenarios that require remote control, such as traffic guidance screens and street pillar screens. The more popular models of asynchronous playback systems include Nova's TB series, Grayscale's C series, Colorite's C series, etc.

Of course, there are some niche application scenarios, such as special-shaped screens, large composite screens for bars, etc.
In this regard, the more popular brand among domestic manufacturers is Mosier, and the display effect of its research and development of special-shaped screens
is still good.

Some customers have other usage requirements, such as adding speakers, adding light sensors to adjust the brightness of the display, remote power control, etc. These can all be achieved by loading the corresponding modules.
