[0024] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] See also Figure 2 , Figure 2 The first embodiment of the method for independently updating multi-area display of an LED display screen of the present invention is shown, which comprises:

[0026] S101, obtaining a partition update data packet;

[0027] When the entire screen is in the initial state, the user can divide the entire screen into areas through the control software to generate partition update data packets, and send the partition update data packets to the LED display screen multi-area display independent update system; in addition, when the entire screen has been divided into areas, the user can also redivide the areas through the control software to generate partition update data packets, and send the partition update data packets to the LED display screen multi-area display independent update system.

[0028] S102, extracting partition update information according to the partition update data packet;

[0029] It should be noted that, after performing protocol conversion on the partition update data packet, the partition update information can be extracted; wherein the partition update information is used to record the target partition status of the entire screen.

[0030] Furthermore, the partition update information includes the region name, region index, reference point coordinates and partition size. For example, the partition update information is: A, 1, x 0 ,y 0 , D 0 , L 0 , it means the area name is A, the area index is 1, and the reference point coordinates are "x 0 ,y 0 " and the partition size is D 0 ×L 0 , that is, with the coordinate "x 0 ,y 0 " is the reference point, the reference point is the starting point of the area, and the width is D 0 , the region length is L 0 as region A and add index 1 to it.

[0031] Therefore, the division position of each area can be accurately determined through the partition update information, thereby achieving effective positioning of each partition.

[0032] S103, parsing the area update content according to the partition update information;

[0033] Specifically, the step of parsing the area update content according to the partition update information includes:

[0034] (1) Traverse the area that needs to be updated according to the partition update information;

[0035] (2) Set the status of the area to be updated to the modified status;

[0036] (3) Analyze the regional update content according to the partition update information;

[0037] (4) Setting the regional display action according to the regional update content;

[0038] Preferably, the area display action includes a jump-in action, a left move action, a right move action, an upward move action, a downward move action, a flashing action, and a frame change action, but is not limited thereto.

[0039] (5) Draw the area display content according to the area update content;

[0040] (6) The state of the area where the area display action setting and area display content drawing are completed is set to the update state.

[0041] S104, performing regional update according to the regional update content;

[0042] Specifically, the steps of performing regional update according to the regional update content include:

[0043] (1) Traverse all areas;

[0044] (2) Determine whether the state of the area is an update state or whether the area display action is a jump action,

[0045] (3) when it is determined that the state of the region is an update state or the region display action is not a jump-in action, the region is updated according to the region display action and the region display content, and the state of the region being updated is set to a drawing state;

[0046] (4) Output the entire screen content for display.

[0047] Therefore, through steps S101-S104, the partition update information can be extracted, the area update content can be parsed, and the area can be updated according to the partition update data packet, thereby achieving effective division of the area.

[0048] S105, obtaining a zone update data packet;

[0049] When the LED display screen has been divided into zones, the user can update one or more zones through the control software to generate a zone update data packet, and send the generated zone update data packet to the LED display screen multi-zone display independent update system.

[0050] S106, extracting area update information according to the area update data packet;

[0051] It should be noted that, after performing protocol conversion on the area update data packet, the area update information can be extracted; wherein the area update information is used to record the target display status of each partition.

[0052] Furthermore, the area update information includes the area name, area index and update content. Since the location and size of the area have been limited when performing the area division in steps S101-S104, the reference point coordinates and the partition size can be omitted in the area update information. For example, the area update information is: A, 1, change the background image to "3.jip", which means that the background image of the area with area name A and index 1 is updated to "3.jip".

[0053] Therefore, each area can be accurately located through the area name and area index, thereby achieving targeted updates.

[0054] S107, parsing the area update content according to the area update information;

[0055] Specifically, the step of parsing the regional update content according to the regional update information includes:

[0057] (2) Set the status of the area to be updated to the modified status;

[0058] (3) parsing the regional update content according to the regional update information;

[0059] (4) Setting the regional display action according to the regional update content;

[0060] Preferably, the area display action includes a jump-in action, a left move action, a right move action, an upward move action, a downward move action, a flashing action, and a frame change action, but is not limited thereto.

[0061] (5) Draw the area display content according to the area update content;

[0062] (6) The state of the area where the area display action setting and area display content drawing are completed is set to the update state.

[0063] S108: Perform regional update according to the regional update content.

[0064] The steps for performing regional updates according to the regional update content include:

[0065] (1) Traverse all areas;

[0066] (2) Determine whether the state of the area is an update state or whether the area display action is a jump action,

[0067] (3) when it is determined that the state of the region is an update state or the region display action is not a jump-in action, the region is updated according to the region display action and the region display content, and the state of the region being updated is set to a drawing state;

[0068] (4) Output the entire screen content for display.

[0069] Therefore, through steps S105-S108, the processes of extracting the regional update information, parsing the regional update content, and updating the regional data packet can be performed, thereby realizing the independent update of one or more regional contents.

[0070] It should be noted that there is no necessary sequence between steps S101-S104 and steps S105-S108. When steps S101-S104 are being performed, steps S105-S108 are also being performed simultaneously.

[0071] In summary, the present invention can realize updating a certain area of ​​the entire screen without affecting the display of other areas of the entire screen, and can frequently update a certain area of ​​the entire screen without the entire screen flashing, with good visual effects; moreover, the time from triggering the update to the entire screen display is short.

[0075] The partition extraction module 3 is used to extract the partition update information according to the partition update data packet; it should be noted that the partition update information can be extracted after the partition update data packet is converted into a protocol; wherein the partition update information is used to record the target partition state of the entire screen. Further, the partition update information includes the area name, area index, reference point coordinates and partition size. For example, the partition update information is: A, 1, x 0 ,y 0 , D 0 , L 0, it means the area name is A, the area index is 1, and the reference point coordinates are "x 0 ,y 0 " and the partition size is D 0 ×L 0 , that is, with the coordinate "x 0 ,y 0 " is the reference point, the reference point is the starting point of the area, and the width is D 0 , the region length is L 0 as region A and add index 1 to it.
