Problems solved by technology

[0005] Therefore, the existing technology requires the staff to have a deep understanding of the splicing and structure of the display screen, and also requires the staff to be very sensitive to the position and can quickly locate the information at these special positions; if the resolution of the display screen is large, then The number of light panels and the number of bright and dark lines will also increase accordingly, and the positioning will be more laborious. There may be situations where the correct position can only be located after multiple positionings, that is, there are problems in terms of operation convenience and high efficiency.

[0029] See figure 1 and figure 2 , a position positioning method applied to LED display devices provided by the first embodiment of the present invention can be realized by the following technical solutions:

[0030] First, after the LED display device such as the LED display screen is built, position information and resolution information of multiple physical splicing units of the LED display device are obtained. Specifically, take the LED box as an example of a physical splicing unit; usually, the LED box is connected to the display control card at the front end (such as the sending card in the synchronous control system) and is equipped with one or more LED light boards and receiving cards. Reading the parameters on the front-end display control card and / or receiving card can obtain the position information and resolution information of the corresponding LED cabinet (physical splicing unit). The position information here is, for example, each LED on the cabinet wiring Th...

[0036] See image 3 and Figure 4 , a position positioning method applied to LED display devices provided by the second embodiment of the present invention can be realized by the following technical solutions:

[0037] First, after the LED display device such as the LED display screen is built, position information and resolution information of multiple physical splicing units of the LED display device are obtained. Specifically, taking an LED light board as an example of a physical splicing unit, the position information and resolution information of each physical splicing unit can be obtained by manually entering or loading a configuration file. The position information here is, for example, the upper left corner of the physical splicing unit The position coordinates of the starting LED pixel on the entire LED display device, and the resolution information is, for example, the number of LED pixels in the row direction and the column direction.

[0045] See Figure 5 , a position positioning method applied to LED display devices provided by the third embodiment of the present invention can be realized by the following technical solutions:

[0046]First, after the LED display device such as the LED display screen is built, position information and resolution information of multiple physical splicing units of the LED display device are acquired. Here, the position information and resolution information of each physical splicing unit can be obtained by reading parameters in the hardware system, or by loading a configuration file or by manual input.

[0047] Next, according to the obtained position information and resolution information of the plurality of physical splicing units, a distribution map of multiple virtual splicing units is generated, wherein the multiple virtual splicing units are assigned different numbers, for example Figure 5 As shown, position numbers 1-4 are respectively marked on the 4 virtual splicin...

Abstract

The invention provides a location positioning method applied to an LED display apparatus, which comprises: (a) acquire location information and resolution ratio information of a plurality of physics splicing units of the LED display apparatus; (b) generate distribution diagrams of a plurality of virtual splicing units, give different numbers respectively to the plurality of virtual splicing units and the numbers are corresponding to the plurality of the physical splicing unit groups one by one; (c) provide image for positioning consistent with the resolution ratio of the LED display apparatus and send the image for positioning to the LED display apparatus in order to enable the plurality of physics splicing unit groups to respectively display the numbers that are the same with the virtual splicing units, for observing display effects by users; and (d) respond to user input operation to select a virtual splicing unit that has the same number with the target physics splicing unit group from the plurality of virtual splicing units, so as to positioning a target physics splicing unit group. Thus, unique location on the LED display apparatus is positioned rapidly; and the positioning to an LED lamp point, lamp plate or box body is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a position positioning method applied to an LED display device. Background technique [0002] LED display is a flat panel display device composed of LED dot matrix. With the rapid development of this industry, LED display is widely used in various occasions of daily life, with adjustable brightness range, safety and environmental protection, energy saving, color It has a series of advantages such as bright colors, large viewing range, and clear content. Compared with other traditional information media, its content is easy to update, low in cost, and good in timeliness. In the display and dissemination of media, it has advantages that other media cannot match. [0003] During the use of the LED display, there will be many situations that require positioning of special positions: a) For example, when adjusting the bright and dark lines caused by splicing, it is necessary to loca...
