In today's era of rapid development of digital information, LED display 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 you to the relevant knowledge of the LED display controller in this article.

 First, the basic functions and principles of the LED display controller

 (A) function analysis

1. Image data processing

LED display controller can receive image data from a variety of sources, such as computers, video cameras, video players and so on. It has a strong image processing ability, the input image decoding, scaling, rotation and other operations to adapt to different specifications and resolution of the LED display. For example, when the input image resolution is not consistent with the display, the controller can scale the image through the algorithm to ensure that the image can be complete and clear on the display, without distortion or blurring.

2. Signal conversion and transmission

Different signal sources output different types of signals, and LED displays need specific digital signals to work properly. Controller bears the burden of signal conversion, the input analog signals or other formats of digital signals into the LED display can identify the signal format. At the same time, it is also responsible for the accurate and error-free transmission of the processed signals to the various pixel points of the display to ensure real-time image and stability. In the transmission process, the controller should ensure the strength and quality of the signal to avoid signal attenuation or interference, thus affecting the display effect.

3. Display control and adjustment

Control of LED display brightness, contrast, color saturation and other parameters is an important function of the controller. By precisely adjusting these parameters, it can make the display show the best visual effect under different ambient light conditions. For example, in the outdoor environment with strong sunlight during the day, the controller can increase the brightness of the display to ensure that the picture is clearly visible; while at night or in the indoor environment with low light, the brightness is appropriately lowered, which not only ensures the viewing comfort, but also saves energy. In addition, the controller can also realize the screen switching, scrolling, flashing and other special effects, adding rich dynamic display effects for the display to attract the attention of the audience.

 (ii) working principle

LED display controller is mainly composed of two parts: hardware and software. Hardware part includes processor, memory, interface circuit, etc., the software part is running on the processor control program.

When the signal source input image data, first through the interface circuit into the controller. The processor reads and analyzes the data, and carries out image processing and signal conversion in accordance with predetermined algorithms and procedures. The processed signal is stored in the memory and transmitted to the LED display through the output interface at the appropriate time. The software program is responsible for coordinating and controlling the whole process, processing and adjusting the image data accordingly to the user's settings and needs, and working with the hardware to ensure the normal display of the display and the realization of various functions.
