Extended Information:
Classification:
1. Synchronous LED Control Card: Primarily used for real-time display of video, graphics, notifications, etc., mainly for indoor and outdoor full-color large-screen displays. A synchronous LED control card system controls the LED display screen in the same way as a computer monitor. It maps images to the computer monitor in real time, with an update speed of at least 60 frames per second. It typically has multi-grayscale color display capabilities, achieving multimedia advertising effects.
Its main characteristics are: strong real-time performance, rich expression, more complex operation, and high price. A typical synchronous LED display control card system consists of a sending card, a receiving card, and a DVI card.
2. Asynchronous LED Display Control Card, also known as an offline LED control card or offline...
Primarily used to display various text, symbols, graphics, or animations. The information displayed on the screen is edited by a computer and pre-loaded into the LED display's memory via an RS232/485 serial port. It is then displayed and played back screen by screen in a loop, offering a variety of display modes. Its main features are: simple operation, low price, and wide applicability.
Simple asynchronous LED control cards can only display digital clocks, text, and special characters. Besides basic system control functions, the most important feature of asynchronous LED control cards is their ability to control the content of different areas of the display screen.
