And selecting a fixed point in the spliced display unit as an origin point, establishing a space coordinate system, and specifically expressing the position of each display screen through the coordinates of the space coordinate system. The target area refers to an area input by an external device and used for displaying information input by the external device, and the position information of the target area can be specifically represented by coordinates of a space coordinate system. The target area may be an area corresponding to any one display screen in the tiled display unit, an area corresponding to any plurality of display screens, or any position of the tiled display unit.

For example, in a tiled display unit in a 3 × 3 tiled format, the coordinate intervals of the LCD1 are: abscissa (0, x1), and ordinate (0, y 1). If the abscissa x is in the range of (0, x1) and the ordinate y is in the range of (0, y1) at any point (x, y) in the target area, the target display screen is the LCD 1. The coordinate intervals of the LCD2 are: abscissa (x1, x2) and ordinate (y1, y2), when the abscissa x of some points is in the range of (0, x1), the ordinate y is in the range of (0, y1), the abscissa x of some points is in the range of (x1, x2), and the ordinate y is in the range of (y1, y2) at any point (x, y) in the target area, the target display screens are the LCD1 and the LCD 2.

And associating the target area with the target display screen, searching a decoding node corresponding to the target display screen, acquiring the coding information of the coding node of the target area, and decoding and displaying the coding information of the target area through the decoding node corresponding to the target display screen. For example, if the target area is an area corresponding to the LCD1 and the target display screen is the LCD1, the target area is associated with the LCD1, and the decoding node corresponding to the LCD1 decodes and displays the encoded information of the target area.
According to the data processing method of the tiled display system, the target display screen is obtained by obtaining the position information of each display screen and the position information of the target area according to the position information of the target area and the position information of each display screen, and the decoding node corresponding to the target display screen is controlled to decode and display the coding node information corresponding to the target area, so that for the display of the input information of the target area, decoding node resources of all display screens in the tiled display system are not occupied for decoding and displaying, the decoding node corresponding to the target display screen is used for decoding and displaying directly, the decoding resources are utilized in a targeted manner, and the utilization rate of the decoding resources can be effectively improved.

In one embodiment, as shown in fig. 5, the data processing method of the tiled display system further includes: step 503, when the target area is an area corresponding to any one display screen, dividing the target area into a plurality of single-screen sub-areas; and 504, associating the single-screen subarea with the target area, and controlling a decoding node corresponding to the target display screen to decode and display the coding node information corresponding to the single-screen subarea. Dividing an M multiplied by N splicing area in a splicing display unit, wherein M and N are positive integers, using the area as a logic LCD, and binding the LCDs in the M multiplied by N splicing area. And when M and N are both positive integers of 1, namely the target area is a 1 × 1 area in the tiled display unit. Dividing the target area into a plurality of single-screen subregions, respectively associating each single-screen subregion with the target area, enabling the target area to correspond to the target display screen, decoding the coded information of the single-screen subregions by the decoding node corresponding to the target display screen, and displaying the decoded information on each single-screen subregion.

Dividing an M multiplied by N splicing area in a splicing display unit, wherein M and N are positive integers, using the area as a logic LCD, and binding the LCDs in the M multiplied by N splicing area. When M and N are both greater than 1, i.e. the target area includes a plurality of 1 × 1 areas, such as 2 × 2 areas, 3 × 2 areas, etc., in the tiled display unit. The target area is taken as a whole and is arbitrarily divided into a plurality of multi-screen subregions, the sub-display screens corresponding to the multi-screen subregions are obtained according to the position information of the multi-screen subregions, and the decoding nodes corresponding to the sub-display screens respectively decode the coding information of the corresponding multi-screen subregions and respectively display the coding information in the multi-screen subregions. The spliced display unit in the spliced display system takes an LCD as a basic unit, the target area takes the LCD as the basic unit, the multi-screen subareas do not take the LCD as the basic unit, and the layers of the multi-screen subareas are arranged on the layer of the target area, so that the spliced display unit only displays the contents of the multi-screen subareas. Windowing and decoding capabilities between regions are completely independent and are not affected by windowing of other regions; and the multi-screen subarea windowing is independent, but the decoding capability is shared and is influenced by the target area and other multi-screen subareas.
As shown in fig. 8, in the tiled display unit in 3 × 3 tiled form, the target area is a 3 × 3 area, and the 3 × 3 area is arbitrarily divided into four sub-areas, for example, sub-area (1), sub-area (2), sub-area (3), and sub-area (4).
