Problems solved by technology
In the above technology, since each display unit needs to be equipped with an infrared receiver, with the increase of the display unit, the number of installed infrared receiving devices will also increase greatly, which will inevitably cause a significant increase in cost. At the same time, multiple transmissions to different display units The infrared commands will also cause mutual interference and affect the reception of infrared commands.

The invention provides an infrared remote control unit, which contains a remote controller, a master control module and subordinate control modules arranged on display units. The remote controller is used for sending an infrared instruction to the master control module. The master control module is used for receiving the infrared instruction sent from the remote controller and forwarding the infrared instruction to the subordinate control module on the corresponding display unit. The subordinate control modules are used for receiving and processing the infrared instruction from the master control module. The invention also provides a splicing wall system. By the adoption of a technology provided by the invention, the installation quantity of infrared receivers in the splicing wall system is minimized, the system cost is saved, mutual interference between infrared instructions of different display units is eliminated, and board routing of hardware is reduced.
Description
technical field [0001] The invention relates to an infrared remote control device and a mosaic wall system, belonging to the technical field of screen mosaic display. Background technique [0002] The screen splicing display wall (splicing wall system) is a brand-new large-screen splicing method. Its biggest feature is that it can be spliced indefinitely. A spliced display unit can be realized through control operations. It can be used as a display alone or with it. Other display units are spliced into a super-large screen for use. The display unit fulfills different use requirements according to different control operations, for example, realizes splicing screen display functions of various lengths and widths, single-screen split display, single-screen independent display, arbitrary combination display, and full-screen display. Splicing display, vertical screen splicing display, optional compensation or cover display of image frame, scaling and stretching display, and...
