Technology | The overall value of the control system in the LED display

The development of LED display in China can be said to be changing with each passing day. The progress made in both technology and the market is amazing. Speaking of promoting the advancement of LED display technology, the control system has to say that its role in the overall value of the LED display is irreplaceable and very important.

From the continuous updating of materials, the progress of gray scale, the reality of color performance and the diversification of correction technology, it is evident that the improvement of control system technology has made extraordinary contributions to the development of LED display screens.

The LED display control system is divided into two types: synchronous and asynchronous. The synchronous control system is almost developed with the development of the LED display. The technology is mature and the market acceptance is high. The asynchronous control system is developed late, flexible in operation, and has its own Application world.

As the "brain" of the LED display, the control system does not account for much of the overall value of the display, but its role is irreplaceable. For example, in the field of door head screens, from banners to single and double colors to full color, this is a continuous evolution of door head advertising. The excellent asynchronous full-color control system can make the door-head full-color display more dazzling and more eye-catching, thereby bringing better advertising effects. Another example is the highway information board, which used to simply display static content such as no drunk driving and no speeding, but the current asynchronous control system allows the display to reflect the road conditions in real time, and eliminates the original "industrial computer + synchronous control system" The solution is more integrated and more convenient for network management and control. The following are two ways to control the system:

1. The LED display with single-chip microcomputer as the controller is limited by the operating speed and communication rate of the single-chip microcomputer, the refresh rate of dynamic display cannot be too high, and the processing of display effects and mobile algorithms is also difficult, and the actual display effect is obvious The flashing sense.

2. The LED display with ARM as the controller, because ARM has high instruction efficiency and clock frequency, so its computing power is very powerful, and the internal resources are also very rich. In the application of strip screen, ARM can be used to achieve a variety of tricks Display mode. The LED display screen with FPGA as the controller, because FPGA is a high-speed, parallel programmable logic device, using it as a controller can process PWM signals at high speed, complete dynamic scanning logic and complete character movement algorithms.

A good control system can make the LED display show more real, more beautiful, and more stable pictures, making the viewer pleasing to the eye.
