With the widespread use of LED displays in both civilian and commercial applications, LED display control cards have rapidly developed in recent years.
The market prospects for LED display control cards are also bright. Door screens of various stores, indoor and outdoor LED advertising screens. Meteorological screens and warning screens on provincial and county-level highways, as well as on major highways. Major enterprises are vigorously researching and developing LED control cards to meet the market demand for LED display screens.
The performance, quality, functionality, and other aspects of LED display control cards are developing rapidly. From the previous wired serial port card and USB card, to the current wireless GSM SMS card and GPRS wireless control card. From monochrome to two-color to full-color. From synchronous control in the past to asynchronous control now.
The LED controller is equipped with a high-performance single-chip microcontroller chip. The controller sends control signals and data to the LED driver chip through an internal control program. The LED driver chip generates corresponding actions based on the requirements of the control signals and data, thereby achieving individual control of each red, green, and blue LED.
If the microcontroller continuously sends control signals and data to a series of LED driver chips, it can enable each LED to receive continuous coordinated control. The expected change effect can be converted into a data format that can be processed by the LED controller and appropriate control instructions, which can be continuously sent to each LED driver chip to make the overall lighting display the desired effect. A software system that is closely integrated with the controller, easy to operate, and powerful in functionality has become necessary here.
