Problems solved by technology
[0006] Whether it is a synchronous LED display system, an asynchronous LED display system or a synchronous asynchronous LED display system, there are still some problems. For example, the synchronous LED display system only supports local media signals, does not support digital media signals such as U disk files, and does not support remote Terminal echo; asynchronous LED display system only supports digital media signals such as U disk files, does not support local media signals, and does not support remote echo; although synchronous and asynchronous LED display systems support local media signals and digital media signals, However, since the local media signal passes through the processor, it will bring additional delay of the local media signal, and remote echo cannot be performed

The embodiment of the invention provides an LED controller, a control method and an LED display screen system, and relates to the technical field of displays. The LED controller comprises a processor, the first input end of the processor is connected with a digital media signal source, and the first output end of the processor is connected with the first input end of a gate; the second input end of the gating device is connected with a local media signal source, and the output end of the gating device is connected with the LED display screen; wherein the gating device is used for selecting one path of media signal from signals output by the digital media signal source and the local media signal source as a target media signal, so that the target media signal is output to the LED display screen to be displayed. According to the embodiment of the invention, extra delay of the local media signal is avoided, and the display of the local media signal and the digital media signal is supported.
Description
technical field [0001] The present application relates to the technical field of displays, and in particular, the present application relates to an LED controller, a control method and an LED display screen system. Background technique [0002] LED (Light Emitting Diode) display system is a system that can be used to display various information such as text, images, videos, and video signals. LED display systems are widely used, such as daily advertising screens, TV screens, etc. etc. are LED display systems. LED display systems can be divided into: [0003] The synchronous LED display system is generally controlled by a computer, which is used to synchronously display the images displayed by the computer, and accesses the local media signal; [0004] The asynchronous LED display system is generally offline, has the ability to store and play automatically, and accesses digital media signals; [0005] Synchronous and asynchronous LED display systems refer to LED displays t...
