Embodiment Construction

[0037] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0038] The splicing screen can include multiple image display screens with the same resolution, and video synchronization can be performed on the image display screens in the same group of splicing screens through conventional video synchronization methods. However, conventional video synchronization methods are not suitable for video synchronization of multiple groups of splicing screens with different resolutions. Based on this, the present invention provides a video synchronization device for multiple groups of spliced ​​screens, which can realize the synchronization of any multiple groups of spliced ​​screens with different resolutions.

Abstract

The invention relates to the technical field of display, particularly provides a video synchronization device for multiple splice displays and display equipment, and aims at solving the technical problem of how to synchronize random multiple splice displays with different resolutions. For achieving the purpose, the video synchronization device comprises a control module, a synchronization signal generation module and multiple output modules, one end of each output module is connected with the synchronization signal generation module, and the other ends of the output modules are connected with image display screens of the splice displays; the synchronization signal generation module is used for generating synchronization signals of the splice displays and selects a synchronization output signal according to a synchronization instruction sent by the control module; and the output modules are used for generating video time sequences of the image display screens and receiving the synchronization signals output by the synchronization signal generation module according to the synchronization instruction sent by the control module to achieve synchronization. Furthermore, the display equipment comprises the video synchronization device. According to the technical scheme, video synchronization can be conducted on random multiple splice displays with different resolutions.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a video synchronization device and a display device for multiple splicing screens. Background technique [0002] The splicing screen is a complete display splicing unit, which can not only be used as a display alone, but also can be used as a super large screen by splicing the display screens. According to different usage requirements, the splicing screen can realize screen split single-screen display or multi-screen display with a variety of large-screen functions: single-screen split display, single-screen separate display, arbitrary combination display, full-screen splicing, vertical screen display, and image borders are optional compensate or cover up. [0003] When there are multiple groups of splicing screens, each group of splicing screens has a video synchronization requirement, that is, video synchronization for each splicing screen is required. However, the current s...
