How to choose the control system of LED display?
If the LED module, LED power supply, wire is the hardware base of the LED display, then the control system is its corresponding software part, similar to the computer “driver”. This article will provide readers with a detailed explanation of the LED display control system which, as well as in the selection of LED display control system should pay attention to matters.
First of all, we know that the LED display is divided into single (double) color and full color two categories, then the corresponding LED display control system is also distinguished into two categories, single (double) color control system and full color control system. In addition, we also need to play according to the LED display is synchronous or asynchronous playback content to distinguish the control system for synchronous and asynchronous systems.
First, single (double) color control system
Single and two-color LED display most of the playback content for the word file, such as many store front display word, there are meetings will be displayed word, and so on, this kind of playback content of the file is relatively small, most of them are a few K, up to 1-2M, the required memory is relatively small, so the single and two-color LED display control system for most of the asynchronous card. The control system sends serial port, network port, USB port, as well as the increasingly popular cell phone WIFI send.
Single and two-color control system is more popular in the following categories: ZH, Huidu, Listen, Feikong, Kuozhi, Kale, NewWing, Qinyuan and other manufacturers of control systems.
Single (dual) color LED display control system generally have readback function, that is, as long as the corresponding software is opened, read back the control card parameters, you can enter different text content in the corresponding editorial interface, edit the finished click on the send, you can replace the original playback of the text content.
Second, full-color control system
Full-color LED display playback content is mostly pictures, videos, PPT and other data larger files, according to the playback requirements, we can use both synchronous playback system, you can also use asynchronous playback system.
Synchronous playback system is used to play video, PPT, its main function is to synchronize with the computer monitor display playback content, i.e., what is played on the computer, LED display play what, mainly used in meetings, offices, stages, large-scale exhibition halls and so on.
Generally in the computer display settings set to “copy mode” (or a small number of multi-screen synchronized playback requirements “extended mode”). Synchronous playback system more popular brands are the following: Novastar, Linsn, Colorlight, Kystar, Huidu, ZH, etc., which in the stage of the large screen application of the market share is higher Novastar and Kystar.
Asynchronous playback system is mostly used to circulate playback of notices, advertisements, promotional pictures, promotional videos, and its main function is to send the content to be played such as text, pictures or videos to the asynchronous memory card for circulating playback, which is mostly used in small exhibition halls, street advertising screens, door screens, traffic guidance screens and other scenarios.
In recent years, as 4G technology matures, the combination of asynchronous playback system loaded with 4G module is also popular in traffic guidance screen, street column screen and other application scenarios that require remote sending control. The more popular models of asynchronous playback systems include Novastar's TB series, Huidu's A series, Colorlight's C series and so on.
Of course, there are some niche application scenarios, such as shaped screen, bar large composite modeling screen, etc., in this regard, domestic manufacturers are more popular brand is Mooncell, its R & D shaped screen display effect is still good.
There are some customers have other needs, such as adding the demand for sound, plus the light sensor to adjust the brightness of the display needs, the demand for remote power control, etc., these are loaded with the corresponding module can be realized.
