Problems solved by technology
[0003] In the prior art, due to the long distance between the sending card and the LED display (it can also be said that the distance between the sending card and the photoelectric conversion device is relatively long), when the user controls the sending card at the sending card end to When controlling the display of the LED display, it is impossible to see the final display effect of the LED display at the same time. In this way, the user needs to run back and forth between the sending card end and the photoelectric conversion device to adjust the output of the sending card according to the effect of the LED display. The terminal controls the sending card, which causes inconvenience to the user

The embodiment of the invention discloses a control method, photoelectric conversion equipment, a display control system and an LED display system. The control method is suitable for a photoelectric conversion device of a display control system, the display controller system further comprises a display controller electrically connected with the photoelectric conversion device, and the control method comprises the steps: receiving a control instruction containing an instruction identifier; determining target control equipment corresponding to the control instruction according to the instruction identifier; and in response to the fact that the target control equipment is the display controller, sending the control instruction to the display controller so as to control the display controller. According to the control method provided by the embodiment of the invention, the photoelectric conversion equipment can perform reverse control on the display controller.
Description
technical field [0001] The present invention relates to the technical field of display control, in particular to a control method, a photoelectric conversion device, a display control system and an LED display system. Background technique [0002] With the development of display screens such as LED display screens, LED display screens have been applied to various scenarios. The current LED display system generally includes a display controller (eg, a sending card), a module controller (eg, a receiving card) and an LED display. The sending card and the receiving card are usually connected by a network cable, and when the LED display is far away from the sending card, due to the limited transmission distance of the network cable, a photoelectric conversion device (which is usually installed near the receiving card end) is usually used as the sending card. The connection bridge between the card and the receiving card to ensure the data transmission from the sending card to the...
