Abstract

The embodiment of the invention provides a transmission method based on HDMI and a related device, and belongs to the technical field of display screen control. The transmission method based on the HDMI comprises the following steps: acquiring the model of a high-definition multimedia interface HDMI, wherein the HDMI is used for signal transmission between the upper computer and the display module; determining a first pin and a second pin of the HDMI according to the model of the HDMI; carrying out the video signal transmission by adopting the first pin, and carrying out the control signal transmission by adopting the second pin, wherein the control signal is used for controlling the display module to display an image corresponding to the video signal. According to the method and the device provided by the embodiment of the invention, the control signal and the video signal can be transmitted at the same time through one HDMI data line, so that the circuit is greatly simplified, the structural complexity of a PCB is reduced, and resources are saved.

Description

technical field [0001] The present application relates to the technical field of display screen control, and in particular to a high definition multimedia interface (highdefinition multimedia interface, HDMI)-based transmission method and related devices. Background technique [0002] With the rapid development of modern industrial technology, LED display has gradually been widely used in people's life and industrial production process. The LED display is not only easy to manufacture, but can maintain normal work in various environments, and the LED display has the characteristics of high resolution, wide viewing range, long viewing distance, and large area. LED displays are usually used in outdoor advertising, commercial display, stage rental, data visualization and other fields. In the LED display control system, the LED display is a flat-panel display spliced ​​by small LED modules or LED cabinets, which is used to display various information such as text, images, and vi...
