Description

Technical Field

[0001] The present invention relates to the technical field of LED display testing, and particularly to a method and device for sending image test data and a display testing system. Background Art

[0002] An LED display is composed of a number of LED display modules, and each LED display module is arranged with a number of LED lamp beads. At the same time, for an LED display with a number of LED lamp beads arranged, due to the diversity and large quantity of its components, it often gets damaged due to the inconsistency in the quality of one or more components, resulting in some light points in the LED display not working properly. To solve this problem, it is necessary to perform aging tests on the LED cabinets. The tests are carried out by sending instructions through software in a PC to detect the brightness and darkness of all lamp beads and whether they can operate for a long time, etc.

[0003] Among them, the current problem is that when aging tests are performed on an LED display, the PC needs to transmit test instructions and image test data through a sending card. When the LED display is large, one sending card cannot send all the image test data. Therefore, multiple sending cards need to be borrowed to achieve the sending of all image test data. Moreover, each time aging tests are performed on different LED displays, a certain number of sending cards need to be connected to the LED display (such as making the connection relationships between multiple sending cards and receiving cards), which significantly reduces the efficiency of the aging tests. Therefore, those skilled in the art urgently need to find a technical solution to solve the above problems. Summary of the Invention

[0004] In view of the above problems, the present invention provides a method for sending image test data. For each sending network port of the sending card, the method includes:

[0005] Obtaining n sets of basic image test data, each set of basic image test data corresponding to a double-screen basic cabinet, where n is the double-screen cabinet base number of the preselected sending network port;

[0006] Determining the data sending times of the sending network port and the basic image test data sent each time according to the total number of cabinets corresponding to the sending network port and the double-screen cabinet base number;

[0008] According to the base image test data sent each time and the corresponding cabinets for each set of base image test data, the base image test data is sent to the corresponding cabinets one by one, so as to send the corresponding base image test data to all the cabinets corresponding to the sending network port.

[0009] Furthermore, according to the total number of cabinets corresponding to the sending network port and the base number of double-screen cabinets, determine the number of data sending times of the sending network port and the base image test data sent each time, including:

[0011] If so, take the quotient of dividing the total number of cabinets by the base number of double-screen cabinets as the number of data sending times m of the sending network port, and determine that the base image test data sent each time is all the base image test data;

[0012] Otherwise, after adding 1 to the quotient of dividing the total number of cabinets by the base number of double-screen cabinets, take it as the number of data sending times m of the sending network port, and determine that the base image test data sent each time in the first m - 1 times is all the base image test data, and the base image test data sent in the mth time is the base image test data corresponding to the first p double-screen base cabinets, where p is the remainder of dividing the total number of cabinets by the base number of double-screen cabinets.

[0013] Furthermore, the base image test data is any one of grayscale test data, grid test data, color bar test data or dot test data.

[0014] Furthermore, the method further includes:

[0015] Determine the total number of cabinets corresponding to the sending network port according to the preset probe card strategy;

[0016] Among them, each sending network port is connected to a receiving card, and a receiving card includes multiple receiving cards connected in series. The preset probe card strategy is: obtain the total number of receiving cards in a receiving card connected to the sending network port, and determine the total number of receiving cards as the total number of cabinets corresponding to the sending network port.

[0017] Furthermore, the sum of the pixel numbers of the cabinets corresponding to the base number of double-screen cabinets is less than or equal to the maximum loadable pixel number of the sending network port.

[0018] The present invention also provides a device for sending image test data. The device includes an acquisition module, a double-screen processing module and a sending module. Among them, for each sending network port of the sending card:

[0019] The acquisition module, connected to the double-screen processing module, is used to acquire n sets of base image test data, and each set of base image test data corresponds to a double-screen base cabinet, and n is the base number of double-screen cabinets of the preselected sending network port;

[0020] The double-screen processing module is connected to the sending module and is used to determine the data sending times of the sending network port and the basic image test data sent each time according to the total number of boxes corresponding to the sending network port and the double-screen box base number; according to the box connection relationship of each box corresponding to the sending network port, the double-screen basic box connection relationship of each double-screen basic box, and the basic image test data sent each time, obtain the boxes corresponding to each set of basic image test data sent each time.

[0021] The sending module is used to sequentially send the basic image test data to the corresponding boxes according to the basic image test data sent each time and the boxes corresponding to each set of basic image test data, so as to send the corresponding basic image test data to all the boxes corresponding to the sending network port.

[0022] Furthermore, the double-screen processing module determines the data sending times of the sending network port and the basic image test data sent each time according to the total number of boxes corresponding to the sending network port and the double-screen box base number, including:

[0023] Judge whether the total number of boxes can be divided evenly by the double-screen box base number;

[0024] If so, use the quotient of dividing the total number of boxes by the double-screen box base number as the data sending times m of the sending network port, and determine that the basic image test data sent each time is all the basic image test data;

[0025] Otherwise, after adding 1 to the quotient of dividing the total number of boxes by the double-screen box base number, use it as the data sending times m of the sending network port, and determine that the basic image test data sent each time in the first m - 1 times is all the basic image test data, and the basic image test data sent in the mth time is the basic image test data corresponding to the first p double-screen basic boxes, where p is the remainder of dividing the total number of boxes by the double-screen box base number.

[0026] Furthermore, the device further includes a probe card module. The probe card module is connected to the double-screen processing module and is used to determine the total number of boxes corresponding to the sending network port according to a preset probe card strategy; wherein, each sending network port is connected to a receiving card, and a receiving card includes multiple serially connected receiving cards. The preset probe card strategy is: obtain the total number of receiving cards in a receiving card connected to the sending network port, and determine the total number of receiving cards as the total number of boxes corresponding to the sending card network port.

[0027] Furthermore, the sum of the pixel numbers of the boxes corresponding to the double-screen box base number is less than or equal to the maximum loadable pixel number of the sending network port.

[0028] The present invention also provides a display screen testing system. The system includes a sending card and an LED display screen. The sending card includes at least one sending network port, and each sending network port is connected to one receiving card in the LED display screen.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0043] In an embodiment of the present invention, a method for sending image test data is disclosed, which is applied in a display screen test system. The display screen test system includes a sending card and an LED display screen. The sending card is provided with a plurality of network ports for connecting to the LED display screen. Specifically, the LED display screen includes at least one receiving card, and each receiving card is connected to a network port in the sending card. In the present invention, the network port connecting the sending card and the receiving card is called the sending network port.

[0044] For each sending network port of the sending card, as Figure 1 shown, the method includes the following steps:

[0045] Step S101: Acquire n sets of basic image test data.

[0046] Where n is the double - screen box base number of the sending network port pre - selected by the technician; the double - screen box base number refers to the number of double - screen basic boxes. That is, if the double - screen box base number is n, there are a total of n double - screen basic boxes. Further, when selecting the double - screen box base number n, it should be ensured that the sum of the pixel numbers of the boxes corresponding to the double - screen box base number is less than or equal to the maximum loadable pixel number of the sending network port. That is, the sum of the pixel numbers of n double - screen basic boxes should satisfy being less than or equal to the maximum loadable pixel number of the sending network port.

[0047] In addition, each set of basic image test data corresponds to a double-screen basic cabinet.

[0048] After the technician pre-selects the double-screen cabinet base number of the sending network port, then according to the double-screen cabinet base number n, n double-screen basic cabinets and the connection relationship between the double-screen basic cabinets are determined.

[0049] For example, if the double-screen cabinet base number is 3, then 3 double-screen basic cabinets are determined, denoted as double-screen basic cabinet 1, double-screen basic cabinet 2, and double-screen basic cabinet 3 respectively. The connection relationship between the double-screen basic cabinets can be double-screen basic cabinet 1 - double-screen basic cabinet 2 - double-screen basic cabinet 3.

[0050] Specifically, in this step, the basic image test data is any one of grayscale test data, grid test data, dot test data, and color bar test data, and the present invention does not limit this.

[0051] The grayscale test data is used to test the grayscale of the LED display screen, that is, to test whether there are grayscale problems with the corresponding light points. Usually, it is tested by making the LED display screen display a pure color picture, such as displaying pure color pictures of red, green, blue, white, cyan, purple, etc.

[0052] The grid test data is used to test whether each row of light points in the LED display screen lights up and dims orderly.

[0053] The color bar test data is used to test whether the color of the light points in the LED display screen transitions evenly when the brightness changes from dark to bright.

[0054] The dot test data, similar to the grid test data, is also used to detect whether the light points light up and dim orderly, including the light and dark of the upper and lower light points, and the frequency of light and dark can be adjusted.

[0055] The aging test combines the functions of grayscale test, grid test, color bar test, and dot test to perform a long-term test on the LED display screen.

[0056] Furthermore, in this step, each set of basic image test data can be different or the same data. The basic image test data can be determined according to different test functions. Among them, when performing grayscale test and dot test, each set of basic image test data is the same data. When performing grid test and color bar test, each set of basic image test data is different data.

[0057] Step S102: Determine the data sending times of the sending network port and the basic image test data sent each time according to the total number of cabinets corresponding to the sending network port and the double-screen cabinet base number.

[0058] Specifically, in one implementation, such asFigure 2 As shown, according to the total number of boxes corresponding to the sending network port and the base number of double-screen boxes, determine the number of data transmissions of the sending network port and the basic image test data transmitted each time, including:

[0059] Step S1021: Determine whether the total number of boxes can be evenly divided by the base number of double-screen boxes. If so, execute Step S1022; otherwise, execute Step S1023.

[0060] Step S1022: Use the quotient obtained by dividing the total number of boxes by the base number of double-screen boxes as the number of data transmissions m of the sending network port, and determine that the basic image test data transmitted each time is all the basic image test data.

[0061] Step S1023: After adding 1 to the quotient obtained by dividing the total number of boxes by the base number of double-screen boxes, use it as the number of data transmissions m of the sending network port. Determine that the basic image test data transmitted each time in the first m - 1 times is all the basic image test data, and the basic image test data transmitted in the mth time is the basic image test data corresponding to the first p double-screen base boxes, where p is the remainder obtained by dividing the total number of boxes by the base number of double-screen boxes.

[0062] Specifically, taking the total number of boxes corresponding to the sending network port as 12 as an example, if the base number of double-screen boxes is 3, that is, there are 3 double-screen base boxes in total, and 3 sets of basic image test data are obtained. Each set of basic image test data corresponds to 1 double-screen base box.

[0063] The total number of boxes 12 can be evenly divided by the base number of double-screen boxes 3. According to the method in Step S1022, the number of transmissions of the sending network port is 4 times, and the basic image test data transmitted each time is all the basic image test data, that is, the basic image test data corresponding to all double-screen base boxes (3 double-screen base boxes) respectively.

[0064] Taking the total number of boxes corresponding to the sending network port as 8 as an example, if the base number of double-screen boxes is 3, that is, there are 3 double-screen base boxes in total, then the number of transmissions of the sending network port is 3 times. The basic image test data transmitted in the first 2 times is all the basic image test data, that is, the basic image test data corresponding to all double-screen base boxes (3 double-screen base boxes) respectively. The basic image test data transmitted in the last 1 time is the basic image test data corresponding to the first p double-screen base boxes. Since p is the remainder obtained by dividing the total number of boxes by the base number of double-screen boxes, at this time p is equal to 2, that is, the basic image test data transmitted in the last 1 time is the basic image test data corresponding to the first 2 double-screen base boxes.

[0065] Specifically, taking the connection relationship of 3 double-screen base boxes as: double-screen base box 1 - double-screen base box 2 - double-screen base box 3 as an example, the first two double-screen base boxes are double-screen base box 1 and double-screen base box 2.

[0066] Step S103: Obtain the cabinets corresponding to each set of basic image test data sent each time according to the cabinet connection relationships of the cabinets corresponding to the sending network ports, the double-screen basic cabinet connection relationships of each double-screen basic cabinet, and the basic image test data sent each time.

[0067] In this step, the cabinet connection relationship is consistent with the connection relationship of the connection cards corresponding to each cabinet. As Figure 3 shown, it is a schematic diagram of the connection between a sending port of sending card one and a receiving card in an LED display screen. Figure 3 There are a total of 8 receiving cards in the receiving cards connected to one sending port of the sending card in [ ], and each receiving card corresponds to a cabinet, that is Figure 3 the total number of cabinets corresponding to one sending port of the sending card in [ ] is 8.

[0068] The connection relationship of the connection cards is receiving card 1 - receiving card 2 - receiving card 3 - receiving card 4 - receiving card 5 - receiving card 6 - receiving card 7 - receiving card 8. If the cabinet corresponding to receiving card 1 is cabinet B1, the cabinet corresponding to receiving card 2 is cabinet B2, the cabinet corresponding to receiving card 3 is cabinet B3, the cabinet corresponding to receiving card 4 is cabinet B4, the cabinet corresponding to receiving card 5 is cabinet B5, the cabinet corresponding to receiving card 6 is cabinet B6, the cabinet corresponding to receiving card 7 is cabinet B7, and the cabinet corresponding to receiving card 8 is cabinet B8, then the cabinet connection relationship is cabinet B1 - cabinet B2 - cabinet B3 - cabinet B4 - cabinet B5 - cabinet B6 - cabinet B7 - cabinet B8.

[0069] Specifically, given the cabinet connection relationships of the cabinets corresponding to the sending network ports, the double-screen basic cabinet connection relationships of each double-screen basic cabinet, and the basic image test data sent each time, for the i-th sending (i is any value in [1, m]):

[0070] If the basic image test data sent in the i-th time is all the basic image test data, that is, n sets of basic image test data are sent in this time, then the n cabinets corresponding to the n sets of basic image test data sent this time should be: in the cabinet connection relationship, the cabinets in the range of the [(i - 1)n + 1, (i - 1)n + 1 + (n - 1)] arrangement positions. According to the double-screen basic cabinet connection relationship of the n double-screen basic cabinets and the cabinet connection relationship of the n cabinets corresponding to the n sets of basic image test data sent this time, one-to-one correspondence is made between the n cabinets corresponding to the n sets of basic image test data sent this time and the n double-screen basic cabinets, and then according to the corresponding relationship between the double-screen basic cabinets and the basic image test data, the cabinets corresponding to each set of basic image test data sent this time are determined.

[0071] If the basic image test data sent for the $i$-th time is the basic image test data corresponding to the first $p$ double-screen basic cabinets, then the $p$ cabinets corresponding to the basic image test data sent this time shall be: in the cabinet connection relationship, the $p$ cabinets with the arrangement positions within the range of $[(i - 1)n + 1, (i - 1)n + 1+(p - 1)]$. According to the double-screen basic cabinet connection relationship of the $n$ double-screen basic cabinets and the cabinet connection relationship of the $p$ cabinets corresponding to the $p$ sets of basic image test data sent this time, the $p$ cabinets corresponding to the $p$ sets of basic image test data sent this time are put into one-to-one correspondence with the first $p$ double-screen basic cabinets, and then based on the correspondence relationship between the double-screen basic cabinets and the basic image test data, the cabinets corresponding to each set of basic image test data sent this time are determined respectively.

[0072] Specifically, for the convenience of understanding, an example is given below. The total number of cabinets corresponding to the sending network port is 8, and the double-screen cabinet base number is 3 (that is, the number of double-screen basic cabinets is 3, and there are 3 sets of basic image test data). The double-screen basic cabinet connection relationship of the 3 double-screen basic cabinets is double-screen basic cabinet 1 - double-screen basic cabinet 2 - double-screen basic cabinet 3. Then the number of sending times of the sending network port is 3 times. The basic image test data sent each time in the first two times is the basic image test data corresponding to all double-screen basic cabinets (that is, 3 sets of basic image test data), and the basic image test data sent for the 3rd time is the basic image test data corresponding to the first 2 double-screen basic cabinets (that is, the basic image test data corresponding to double-screen basic cabinet 1 and double-screen basic cabinet 2).

[0073] Then the cabinets corresponding to the basic image test data sent for the first time are the cabinets with the arrangement positions within the range of $[(i - 1)n + 1, (i - 1)n + 1+(n - 1)]$ in the cabinet connection relationship, where $i = 1$ and $n = 3$, that is, the 3 cabinets with the arrangement positions within the range of $[1, 3]$, that is, Figure 3 the cabinets B1, B2, and B3 in. Since the cabinet connection relationship of cabinets B1, B2, and B3 is cabinet B1 - cabinet B2 - cabinet B3, and the double-screen basic cabinet connection relationship of the 3 double-screen basic cabinets is double-screen basic cabinet 1 - double-screen basic cabinet 2 - double-screen basic cabinet 3, then according to the double-screen basic cabinet connection relationship of the 3 double-screen basic cabinets and the cabinet connection relationship of the 3 cabinets corresponding to the 3 sets of basic image test data sent this time, it is determined that cabinet B1 corresponds to double-screen basic cabinet 1, cabinet B2 corresponds to double-screen basic cabinet 2, and cabinet B3 corresponds to double-screen basic cabinet 3. That is, for the 3 sets of basic image test data sent for the first time, the basic image test data of double-screen basic cabinet 1 corresponds to cabinet B1, the basic image test data of double-screen basic cabinet 2 corresponds to cabinet B2, and the basic image test data of double-screen basic cabinet 3 corresponds to cabinet B3. The same applies to other sending times.

[0074] Step S104: According to the basic image test data sent each time and the corresponding cabinets for each set of basic image test data, sequentially send the basic image test data to the corresponding cabinets, so as to send the corresponding basic image test data to all the cabinets corresponding to the sending network ports.

[0075] For the image test data sending method provided in this embodiment, for each sending network port of the sending card, by adopting the above-mentioned double-screen method, obtain the basic image test data sent each time and the corresponding cabinets for each set of basic image test data, and sequentially send the basic image test data to the corresponding cabinets, so as to send the corresponding basic image test data to all the cabinets corresponding to the sending network port, thereby enabling the image test data to be sent to LED display screens of various resolutions through all the sending network ports on one sending card, reducing the number of sending cards used, only requiring one sending card to be connected to the LED display screen, improving the sending efficiency of the image test data, and further improving the aging test work efficiency of the LED display screen.

[0076] In another embodiment of the present invention, as Figure 4 shown, the method further includes:

[0077] Step S105: Determine the total number of cabinets corresponding to the sending network port according to the preset card detection strategy.

[0078] Specifically, as Figure 3 shown, each sending network port is connected to one receiving card, and one receiving card includes multiple receiving cards connected in series.

[0079] The preset card detection strategy is: obtain the total number of receiving cards in one receiving card connected to the sending network port, and determine the total number of receiving cards as the total number of cabinets corresponding to the sending card network port.

[0080] In another embodiment of the present invention, when there are multiple sending network ports in the sending card, multiple sending network ports can simultaneously perform double-screen processing according to the steps in Figure 1 or Figure 4 to send the basic image test data to all the cabinets in the LED display screen. The selection of the specific number of network ports is determined according to the number of pixel points in the screen.

[0081] The present invention also provides an image test data sending device, as Figure 5 shown, the device includes an acquisition module 501, a double-screen processing module 502, and a sending module 503. Among them, for each sending network port of the sending card:

[0082] An acquisition module 501, connected to a double-screen processing module 502, is configured to acquire n sets of basic image test data, where each set of basic image test data corresponds to a double-screen basic cabinet, and n is the double-screen cabinet base number of the preselected transmission network port;

[0083] The double-screen processing module 502, connected to the sending module 503, is configured to determine the data sending times of the sending network port and the basic image test data sent each time according to the total number of cabinets corresponding to the sending network port and the double-screen cabinet base number; obtain the cabinets corresponding to each set of basic image test data sent each time according to the cabinet connection relationship of each cabinet corresponding to the sending network port, the double-screen basic cabinet connection relationship of each double-screen basic cabinet, and the basic image test data sent each time;

[0084] The sending module 503 is configured to sequentially send the basic image test data to the corresponding cabinet according to the basic image test data sent each time and the cabinets corresponding to each set of basic image test data, so as to send the corresponding basic image test data to all the cabinets corresponding to the sending network port.

[0085] In the image test data sending device provided in this embodiment, for each sending network port of the sending card, by adopting the double-screen method, the basic image test data sent each time and the cabinets corresponding to each set of basic image test data are obtained, and the basic image test data is sequentially sent to the corresponding cabinets, so as to send the corresponding basic image test data to all the cabinets corresponding to the sending network port; by using the image test data sending device provided by the present invention, the image test data is sent to the cabinets corresponding to each sending network port on the invention card, so that it is possible to send the image test data to LED display screens of various resolutions through all the sending network ports on one sending card, reduce the number of sending cards used, improve the sending efficiency of the image test data, and further improve the aging test work efficiency of the LED display screen.

[0086] In another embodiment of the present invention, the double-screen processing module 502 determines the data sending times of the sending network port and the basic image test data sent each time according to the total number of cabinets corresponding to the sending network port and the double-screen cabinet base number, including:

[0087] Judge whether the total number of cabinets can be divided evenly by the double-screen cabinet base number;

[0088] If so, use the quotient of dividing the total number of cabinets by the double-screen cabinet base number as the data sending times m of the sending network port, and determine that the basic image test data sent each time is all the basic image test data;

[0089] Otherwise, after adding 1 to the quotient of dividing the total number of boxes by the base number of double-screen boxes, use it as the number of data transmission times m for the sending network port, and determine that the basic image test data sent each time in the previous m - 1 times is all the basic image test data, and the basic image test data sent in the mth time is the basic image test data corresponding to the first p double-screen basic boxes, where p is the remainder of dividing the total number of boxes by the base number of double-screen boxes.

[0090] In another embodiment of the present invention, as Figure 6 shown, the device further includes a probing card module 504, and the probing card module 504 is connected to the double-screen processing module 502, and is used to determine the total number of boxes corresponding to the sending network port according to a preset probing card strategy; wherein, each sending network port is connected to a receiving card, and a receiving card includes a plurality of receiving cards connected in series, and the preset probing card strategy is: obtain the total number of receiving cards in a receiving card connected to the sending network port, and determine the total number of receiving cards as the total number of boxes corresponding to the sending network port.

[0091] In another embodiment of the present invention, the sum of the pixel numbers of the boxes corresponding to the base number of double-screen boxes is less than or equal to the maximum loadable pixel number of the sending network port.

[0092] As Figure 7 shown, the present invention also provides a display screen test system, and the system includes a sending card 701 and an LED display screen 702. The sending card 701 includes at least one sending network port, and each sending network port is connected to a receiving card in the LED display screen. Each receiving card includes a plurality of receiving cards connected in series, and each receiving card corresponds to a box, wherein:

[0093] The sending card 701 realizes sending the corresponding basic image test data to all the boxes in the LED display screen through the above method for sending image test data;

[0094] All the boxes in the LED display screen 702 display the received corresponding basic image test data to complete the test of the display screen.
