Embodiment Construction

[0030] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0031] Such as figure 1 and figure 2 As shown, the present invention provides a kind of LED display screen automatic screen connection method, and it comprises the following steps:

[0032] Step S01: Power on and initialize to display the one-dimensional coordinate digital information of the LED display;

[0033] After the LED display is spliced ​​and connected to the cabinet, it is powered on. Power on and display the initial screen of the LED display screen. In the initial screen of the display screen, each box unit of the display screen displays its own unique identification information. These identification information can be numbers, letters, one-dimensional barcodes, two-dimensional c...

Abstract

The invention discloses an automatic continuous screen method of an LED display. The method comprises the steps that digital information of one-dimensional coordinates of an LED display screen is displayed at the initialization of a power-on operation; digital image information of the initialized one-dimensional coordinates is obtained; the total number N of LED display screen cases is determined; the number of rows or columns of the LED display screen is determined; the digital image of the initialized one-dimensional coordinates of the display screen is cut into N parts according to the row and column arrangement situation of the cases through a specific image processing technology; the content information of the cut-out N parts of images is identified; physical location information of the corresponding display screen cases is determined through the display content of each part of cut image; the physical location information of each display screen case is sent to an LED display screen control system. The automatic continuous screen method of the LED display solves the problem of high cost caused by extra increase in number of hardware such as transmitters, receivers and the like as required by existing LED display automatic continuous screens.

Description

technical field [0001] The invention relates to the field of small-pitch LED display screens, and more specifically relates to an automatic screen-connecting method for LED display screens. Background technique [0002] The LED display screen is spliced ​​by several unit boxes, and each box is connected in series through signal cables and power cables to form a whole. In the process of assembling and splicing the LED display screen, it is necessary to determine the position of each cabinet on the screen in the control system, so that the control system can send the content of a certain area in the display screen to the cabinet at the corresponding position, so that the whole The display screen can be normal. [0003] Therefore, to determine the screen connection parameters is to determine the coordinate position of the cabinet in the screen, which is the setting work that must be completed when assembling the splicing screen. The traditional method is to manually set the n...
