Abstract

An operation method is provided for a display system displaying a physical image comprising several physical sub-images. The display system comprises a display wall having several display modules for displaying physical sub-images and a control interface having a first display region and a second display region. The operation method comprises following steps. Displaying several virtual block images on the first display region. Displaying several display module connection images on the second display region. Dragging the virtual block images from the first display region to the second display region corresponding to the display module connection images. Wherein the physical connection configuration for the display modules is arranged according to the corresponding relationship between the virtual block images and the display module connection images.

First claim

What is claimed is:

1. A display system for displaying a physical image, the physical image comprises a plurality of physical segmentation images, the display system comprising:
a display wall, comprising a plurality of display modules, the display modules are used to correspondingly display the physical segmentation images, the display modules have a physical connection configuration in the display wall, and the physical connection configuration is related to a physical address of each of the display modules;
a host controller, coupled to the display wall, and used to allocate the physical connection configuration of the display modules; and
a processing device, coupled to the host controller, the processing device comprising:
a control interface, comprising a first display region and a second display region, the first display region is used to display a plurality of virtual block images, the second display region is used to display a plurality of display module connection images, wherein the virtual block images have formats and contents consistent with the physical segmentation images and the display module connection images, and the virtual block images have same resolutions with the physical segmentation images, and the display module connection images respectively correspond to the display modules,

wherein, the processing device is used to drag the virtual block images from the first display region to the second display region so as to correspond to the display module connection images, and the host controller is used to allocate the physical connection configuration of the display modules according to a relationship between the virtual block images and the display module connection images.

2. The display system according to claim 1 , wherein, when the virtual block images are dragged from the first display region to the second display region to correspond to the display module connection images, the virtual block images are correspondingly located at positions of the display module connection images in the second display region.

3. The display system according to claim 1 , wherein:
each of the virtual block images has a division address, and the each division address is encoded into a division address code word, the physical addresses of the display modules have a mapping relationship with the division address code words of the virtual block images;
the processing device establishes the mapping relationship according to the relationship between the virtual block images and the display module connection images; and
the host controller allocates the physical connection configurations of the display modules according to the mapping relationship.

4. The display system according to claim 3 , wherein, each of the virtual block images is located in a vertical column and a horizontal row of the first display region, the vertical column has a column code, and the horizontal row has a row code, the division address of each the virtual block image is related to the row code and the column code.

5. The display system according to claim 3 , wherein, the processing device further comprises:
a first storage circuit, used to store the division address code words, and update the division address code words when the mapping relationship is established.

6. The display system according to claim 1 , wherein, the physical connection configuration of the display modules forms a daisy chain configuration, and the physical connection configuration comprises a plurality of chain channels, and each the chain channel comprises a plurality of chain nodes, and each the display module corresponds to one of the chain channels and one of the chain nodes.

7. The display system according to claim 6 , wherein, each of the chain channels has a chain channel code, each of the chain nodes has a chain node code, and the physical address of each of the display modules is related to the chain channel code and the chain node code.

8. The display system according to claim 6 , wherein, each of the display module connection images corresponds to one of the chain channels and one of the chain nodes in the second display region.

9. The display system according to claim 6 , wherein, when each of the chain channels comprises different amounts of the chain nodes, the physical connection configuration forms an asymmetric connection configuration.

10. The display system according to claim 1 , wherein:
the amount of the physical segmentation images, the amount of the virtual block images, the amount of the display module connection images and the amount of the display modules are all equal to a first amount; and
the display wall and the physical image both have a first resolution, and each of the display modules, each of the physical segmentation images and each of the virtual block images all have a second resolution, and the first amount is equal to the first resolution divided by the second resolution.

11. The display system according to claim 10 , wherein, the host controller detects a pitch between light-emitting elements of each of the display modules, and calculates the second resolution of each of the display modules according to the pitch between light-emitting elements.

12. The display system according to claim 11 , wherein:
the host controller detects whether each of the display modules is normally installed on the display wall, and generates a detection result; and
when the virtual block images are dragged from the first display region to the second display region so as to correspond to the display module connection images and the detection result is “No”, the virtual block images are not located at the positions of the display module connection images corresponding to the display modules which are abnormally installed.

13. The display system according to claim 12 , wherein, when one of the display modules has the second resolution which is different, the display module is detected as abnormally installed.

14. An operation method of a display system, the display system is used to display a physical image, the physical image comprises a plurality of physical segmentation images, the display system comprises a display wall and a control interface, wherein the display wall comprises a plurality of display modules, the display modules are used to correspondingly display the physical segmentation images, the display modules have a physical connection configuration in the display wall, and the physical connection configuration is related to a physical address of each of the display modules, and the control interface comprises a first display region and a second display region, the operation method comprises the following steps:
displaying a plurality of virtual block images in the first display region, wherein the virtual block images have formats and contents consistent with the physical segmentation images and the display module connection images, and the virtual block images have same resolutions with the physical segmentation images;
displaying a plurality of display module connection images in the second display region, the display module connection images respectively correspond to the display modules;
