Abstract

A spliced display device and a configuration method thereof, and a display server and a control method thereof are provided. The configuration method may be applied to a spliced display device, and the spliced display device includes a plurality of displays spliced together in an array. The configuration method includes: receiving display control information sent by a display server in a preset protocol format, wherein the display control information at least includes position setting information; and configuring the plurality of displays according to the display control information.

First claim

What is claimed is:

1. A configuration method for a spliced display device, wherein the spliced display device comprises a plurality of displays spliced together in an array, and the configuration method comprises:
receiving display control information sent by a display server in a preset protocol format, wherein the display control information at least comprises position setting information; and configuring the plurality of displays according to the display control information,
wherein the configuring the plurality of displays according to the display control information comprises: setting s display position of a start display of the plurality of displays according to the position setting information; modifying the position setting information to obtain a next position setting information, and transmitting the next position setting information obtained by the modifying to a next display; and setting a display position of the next display according to the next position setting information, and
wherein the configuring the plurality of displays according to the display control information further comprises:
determining whether the next display is a last display; and
in a case where it is determined that the next display is not the last display, performing the modifying the position setting information to obtain a next position setting information, and the transmitting the next position setting information obtained by modifying to a next display; and the setting a display position of the next display according to the next posit km setting information.

2. The configuration method according claim 1 , wherein the display control information further comprises display debugging information,
the configuring the plurality of displays according to the display control information further comprises:
performing display parameter debugging on a specified display of the plurality of displays according to the display debugging information and preset display position information of the displays.

3. The configuration method according to claim 2 , wherein the display debugging information at least comprises a second function identification parameter, a first debugging position parameter, a debugging display parameter and a first debugging connection position parameter; the preset display position information at least comprises a display position parameter;
the performing display parameter debugging on a specified display of the plurality of displays according to the display debugging information and preset display position information of the displays comprises:
transmitting the display debugging information to the start display of the plurality of displays according to the first debugging connection position parameter;
determining a display mode of the start display to be collaborative display or separate display and starting to execute a display parameter debugging function, according to the second function identification parameter;
comparing the first debugging position parameter with a preset display position parameter of the start display; in a case where the first debugging position parameter is the same as the preset display position parameter of the start display, determining the start display as the specified display;
in a case where the first debugging position parameter is different from the preset display position parameter of the start display, modifying the first debugging connection position parameter to obtain a next first debugging connection position parameter;
transmitting the display debugging information to a next display next to the start display according to the next first debugging connection position parameter; comparing the first debugging position parameter with a preset display position parameter of the next display, repeating this process until a display of which a preset display position parameter is the same as the first debugging position parameter is found out, and determining the display of which a preset display position parameter is the same as the first debugging position parameter as the specified display; and
debugging the specified display of the plurality of displays according to the debugging display parameter.

4. The configuration method according to claim 3 , wherein the debugging display parameter comprise a display brightness parameter, a display contrast parameter, a display color saturation parameter, and a gain parameter and an offset parameter of pixels comprised in the specified display;
the debugging the specified display of the plurality of displays according to the debugging display parameter comprises:
adjusting a display brightness of the specified display according to the display brightness parameter;
adjusting a display contrast of the specified display according to the display contrast parameter;
adjusting a display color saturation of the specified display according to the display color saturation parameter;
adjusting a gain of the pixels comprised in the specified display according to the gain parameter of the pixels comprised in the specified display; and
adjusting an offset of the pixels comprised in the specified display according to the offset parameter of the pixels comprised in the specified display.

5. The configuration method according to claim 2 , further comprising determining a display position serial number corresponding to each of the displays according to the preset display position information of the displays;
the display debugging information at least comprises a second function identification parameter, a second debugging position parameter, a debugging display parameter and a second debugging connection position parameter;
the performing display parameter debugging on a specified display of the plurality of displays according to the display debugging information and preset display position information of the displays comprises:
transmitting the display debugging information to the start display of the plurality of displays according to the second debugging connection position parameter;
determining a display mode of the start display to be collaborative display or separate display and starting to execute a display parameter debugging function, according to the second function identification parameter;
comparing the second debugging position parameter with the display position serial number corresponding to the start display; in a case where the second debugging position parameter is the same as the display position serial number corresponding to the start display, determining the start display as the specified display;
in a case where the second debugging position parameter is different from the display position serial number corresponding to the start display, modifying the second debugging connection position parameter to obtain a next second debugging connection position parameter;
transmitting the display debugging information to a next display next to the start display according to the next second debugging connection position parameter; comparing the second debugging position parameter with the display position serial number corresponding to the next display, repeating this process until a display of which the display position serial number is the same as the second debugging position parameter is found out, and determining the display of which the display position serial number is the same as the second debugging position parameter as the specified display; and
debugging the specified display of the plurality of displays according to the debugging display parameter.

6. The configuration method according to claim 5 , wherein the debugging display parameter comprise a display brightness parameter, a display contrast parameter, a display color saturation parameter, and a gain parameter and an offset parameter o
