All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the invention provides an L ED display screen system architecture supporting multifunctional display, which includes a first main control card, a second main control card, a sending card, and display modules, where the display modules are spliced into a L ED display screen.
The first main control card provides a first video signal and outputs the first video signal to the second main control card. An operating system is written in the first main control card, and the operating system generates a system video signal; the first main control card receives a two-dimensional video signal. The embodiment also comprises an OPS computer, and the OPS computer generates an OPS video signal and outputs the OPS video signal to the first main control card. The first main control card outputs any one of a system video signal, a two-dimensional video signal and an OPS computer video signal as a first video signal.
The user can switch the system video signal, the two-dimensional video signal or the OPS computer video signal in the first main control card according to the use requirement to be used as the first video signal to be output.
The embodiment further comprises a human-computer interaction device, wherein the human-computer interaction device generates a driving signal and outputs the driving signal to the first main control card, an operating system of the first main control card receives the driving signal or the first main control card outputs the driving signal to the OPS computer, the human-computer interaction device is composed of one or more of a mouse, a remote controller, an infrared frame, a keyboard, a touch screen and a handwriting board, in the first embodiment, the human-computer interaction device is preferably the infrared frame, and the infrared frame is arranged on the edge of the L ED display screen and serves as a touch source.
The man-machine interaction device obtains an operation instruction of a user and converts the operation instruction into a driving signal, and an operating system in the first main control card receives the driving signal and operates according to the driving signal. When the OPS computer is connected with the first main control card, a user can select the first main control card to output the driving signal to the OPS computer, and the OPS computer operates according to the driving signal.
The second main control card receives any one or more of the two-dimensional video signal, the three-dimensional video signal and the first video signal, randomly switches, splices, moves, scales, superposes and crosses the screen to roam and generate a second video signal, and outputs the second video signal to one or more sending cards.
And the second video signal produced by the second main control card is in a three-dimensional video format which can be identified by the sending card. In the shutter type 3D display method, an image is divided into two according to frames by improving the refresh rate of a display module, two groups of pictures which are continuously staggered with the left eye and the right eye are formed, and a viewer wears shutter type three-dimensional glasses to enable the two groups of pictures to respectively enter the left eye and the right eye, so that a three-dimensional image is synthesized through the human brain.
The second main control card is provided with a plurality of video signal output ports, and each video signal output port can be independently provided with output resolution, so that video splicing of the following equipment is realized.
And the sending card is used for receiving the second video signal, cutting the second video signal, packaging and distributing the second video signal to one or more receiving cards of the display modules.
Since each sending card is required to have a display resolution halved to realize the 3D function, that is, the total number of the sending card loads in the prior art is L × Q dots, the sending card in this embodiment can only have L × Q/2 dots, for example, the original sending board after 3D is supported by 1920 × 1080 dots can only support 1920 × 1080/2 dots, and the horizontal reduction, the vertical reduction or the simultaneous horizontal and vertical reduction can be performed as long as the tape load requirement is satisfied.
In addition, the net port load output to the display module by the sending board is also reduced by half correspondingly, namely the original net port maximum load of 65 ten thousand points supports 32 ten thousand points, so that the number of modules which can be connected in series by each net port is reduced by half correspondingly, the number of the modules in the system architecture diagram is changed from the previous sending board into K, and K is more than or equal to 1 according to the size of the screen volume points, for example, the resolution of an all-in-one machine is 1920 x 1080 points, a sending board with 1920 x 1080 load is used previously, 2 sending boards with 1920 x 1080 load are needed currently, but if the sending board with 3840 x 2160 load is selected, only one sending board is needed, if the resolution of L ED display screen is 960 x 1080, a sending board with 1920 x 1080 previously is used previously, and under the new real system architecture, a sending board with 1920 x 1080 points is still used.
It should be noted that, with the development of the integration technology, the functions of the first main control card and the second main control card in the present invention may be integrated into a whole and integrated on one main control card, and the principle of the present invention is considered to be the same.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
