Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] Aiming at the problems existing in the prior art, the embodiment of the present invention proposes a decoding board with shunt function. The decoding board uses a video processor chip model NT68380 in conjunction with a DP input interface circuit and a DP output interface circuit to realize signal shunting.

[0043] figure 2 The circuit structure of the decoder board provided by the embodiment of the present invention is shown.

[0044] The decoding board that the embodiment of the present invention provides at least includes: DP input interface circuit 12; DP output interface circuit 13; ...

Abstract

The invention relates to the technical field of display, and provides a decoding board and display equipment provided with a splicing screen. The decoding board adopts NT68380 type video processor chip; as the NT68380 type video processor chip has a video signal splitting processing capacity, combination of the NT68380 type video processor chip with a DP (Data Processing) input interface circuit and a DP output interface circuit can realize the decoding board with the splitting capacity. When such a decoding board is applied to the display equipment provided with the splicing screen, a host side can adopt a general display card, without needing a specific display card, so that equipment cost is lowered; moreover, either star topology or daisy chain topology can be adopted between a host and respective split screens; wiring is simple and convenient, and inherent defects of the star topology per se can be avoided.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a decoding board and a display device with a splicing screen. Background technique [0002] At present, there is an increasing demand for large-size and ultra-large-size display devices in the market: such as billboards in shopping malls / squares, monitoring / security, competitions / performances, etc. Because the cost of a single-screen large-size display is very high, and it is inconvenient to transport and install, some manufacturers have introduced a display device composed of multiple screens, which can not only meet the requirements of large-area display, but also control it well. The cost of the product. [0003] However, in the display devices with splicing screens provided by the prior art, the decoder boards equipped with each single screen are general-purpose boards, and the boards themselves do not have the function of signal shunting, and the shunting of signals can on...
