Synchronous signal processing method and synchronous signal processing device for spliced-screen body stereoscopic display, and spliced-screen body

Abstract

The invention provides a synchronous signal processing method and a synchronous signal processing device for spliced-screen body stereoscopic display, and a spliced-screen body, wherein the spliced-screen body comprises a plurality of module screens spliced with one another. The method comprises the following steps of: selecting a first module screen from the plurality of module screens according to a preset rule; obtaining a synchronous signal for stereoscopic display via the first module screen, wherein the synchronous signal is used for indicating the plurality of module screens to perform synchronous display on video images; and transmitting the synchronous signal to the other module screens via the first module screen according to a preset rule. With the adoption of the technical scheme provided by the invention, the technical problems of high cost, complex realization and the like existing in synchronous signal transmitting schemes in the related technologies are solved, thus reducing the complexity of a synchronization mode while reducing the cost.

Description

technical field [0001] The present invention relates to the field of splicing screen display, in particular to a synchronous signal processing method and device for three-dimensional display of a splicing screen, and a splicing screen. Background technique [0002] The application of large-size frame color screens (such as full-color LEDs) has become more and more widespread. This kind of display screen with ultra-high physical resolution is generally made of split screen modules for multi-screen splicing. With the development of display technology , Stereoscopic display is more and more widely used in splicing screens, but since the stereoscopic image involves the synchronous display of the left and right eye images, and the display of the stereoscopic image on the screen needs to be synchronized with the 3D glasses, therefore, this requires any splicing The screens need to be synchronized with the 3D glasses, but the actual situation is that for the display of the spliced ...

Problems solved by technology

[0004] However, the above processing schemes are all sent by the synchronous processor to each module screen. In the case of a large-sized screen, a long connecting wire is required, and a synchronization signal suitable for long-distance transmission needs to be generated, especially for more splicing. The module screen cascades the synchronous device to send synchronously. The complexity of this synchronous mode is high and the cost is increased.

[0005] For the above-mentioned problems in related technologies, no effective solution has been proposed yet
