[0037] Such as figure 1 As shown, a spliced ​​display screen matching method provided in the first embodiment of the present invention includes:

[0038] Step S11: receiving a screen distribution information display command;

[0039] Step S13: generating a screen distribution information image;

[0040] Step S15: storing the screen distribution information image;

[0041] Step S17: Embedding the screen distribution information image into the background image corresponding to the loading display area to obtain the target image;

[0042] Step S19: Display the target image in the loading display area.

[0043] To facilitate a clearer understanding of this embodiment, specific examples are given below to describe the foregoing steps S11-S19 in detail.

[0044] In step S11, the screen distribution information display command may be generated by the host computer and transmitted to the splicing unit of the spliced ​​display screen such as the display control card on the LED cabine...

Abstract

The application provides a configuring method for a splicing-type display device, the configuring method includes: receiving a configuration information display command; in response to the configuration information display command, extracting fonts from a font library according to configuration information and stitching the extracted fonts to thereby generate a configuration information image, wherein the configuration information includes driving port information and a cascading serial number, and the configuration information image at least includes the cascading serial number; storing the configuration information image; embedding the stored configuration information image into a background image corresponding to a driven display area to thereby obtain a target image; and displaying the target image in the driven display area. The application further provides a configuring apparatus and a display device control card adapted for performing the configuring method.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a spliced ​​display screen distribution method, a display screen control card and a spliced ​​display screen distribution device. Background technique [0002] At present, LED display has gained more and more market attention due to its high dynamics and high color. More and more advertisers and merchants are more inclined to choose LED display as Factors such as the cost and maintenance of outdoor screens deter some customers, but the emergence of screen rental manufacturers has solved this problem, and the area of ​​outdoor publicity screens has also been further expanded. The prosperity of the display rental market has also given display screens The control system brings new opportunities and challenges. At the same time, the rental screen is generally large, so many cabinets are required to be cascaded, and the connection and configuration of the cabinets has become a compli...
