Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Fig. 1 is a flow chart of a debugging method of a display device according to an embodiment of the present invention, where the display device includes at least two cascaded display module units, and the cascaded sequence between the different display module units is random. The display device may have a regular shape or a special shape. The method may be performed by a commissioning device of a display device, which may be integrated within a receiving card. The method specifically comprises the following steps:
s110, sequentially grouping and marking test data according to initial configuration parameters of the display module units to form at least two test picture data group units, wherein the number of the test picture data group units is greater than or equal to that of the display module units;
the display device can be formed by cascading at least two display module units through a flat cable, and each display module unit comprises at least one display module. The cascading order among different display module units is random. The initial configuration parameters of the display module unit may be provided by the host computer and the transmitting card. Fig. 2 is a schematic diagram of a debugging system of a display device according to an embodiment of the present invention. As shown in fig. 2, the upper computer 100 is connected to the transmitting card 200 through a high-definition multimedia interface (High Definition Multimedia Interface, HDMI) and a universal serial bus (Universal Serial Bus, USB), wherein HDMI can be used for transmitting display screen data and USB can be used for transmitting configuration parameters of the display module unit. In the debugging process, the host computer 100 transmits the initial configuration parameters of the display module unit through the USB. The transmitting card 200 converts the configuration parameters of the display screen data and the display module unit into network data and transmits the network data to the receiving card 300, the receiving card 300 sequentially groups the test data according to the received initial configuration parameters of the display module unit, and sequentially marks each group of test data to form corresponding marks, so that each test screen data group unit comprises the test data and the mark data, and simultaneously buffers the test screen data group unit. The test picture data included in each test picture data set unit can be matched with the corresponding display module unit, so that the display module unit can normally display the test picture data included in the corresponding test picture data set unit. For example, the initial configuration parameters of the display module unit may include a resolution of the display module unit, and the number of pixels in different directions of the display module unit may be determined according to the resolution of the display module unit. Therefore, the test data amount of the corresponding test picture data group unit can be determined according to the resolution of the display module unit, and the grouping of the test data can be realized. And the test picture data set unit also comprises label data, and when the test picture data set unit is output to the corresponding display module unit, the display module unit can display labels according to the label data. In addition, the number of the test picture data group units formed by the test data can be the maximum number of the data group units which can be supported by the debugging device of the display device, so that the number of the test picture data group units can be ensured to meet the requirement of the display module unit when the debugging device of the display device is connected with any display module unit in the number range which can be supported. For example, when the debugging device of the display device is integrated in the receiving card 300, the receiving card 300 may be connected to at most 32 display module units, that is, the maximum number of data group units that the receiving card 300 can support is 32.

As shown in fig. 3, the display device is exemplarily shown to include four display module units corresponding to the right four test picture data set units. The labels of the different display module units are G1-1, G2-1, G3-1 and G4-1 respectively.

Therefore, the cascading sequence of the four display module units can be determined to be an upper right display module unit, an upper left display module unit and a lower left display module unit in sequence.
It should be noted that, when at least two test picture data units are output to the display module unit for display, the at least two test picture data units are buffered by the original frame buffer module and then output to the data reorganizing module, the data reorganizing module reorganizes the test picture data units to form display frame data, and buffers the display frame data by the display frame buffer module, and then outputs the display frame data to the display module unit by the port transponder, so that the display module unit displays the display frame data. The port repeater may be a multiport repeater, for example.
S130, updating initial configuration parameters according to the labels of the display module units, and completing debugging of the display device.
After the display module units display the labels according to the label data in the test picture data group units, the cascading sequence of different display module units can be determined according to the labels of different display module units, and initial configuration parameters are updated according to the cascading sequence of different display module units, so that when different display module units acquire data subsequently, the data corresponding to the cascading sequence can be directly acquired according to the updated configuration parameters, normal display of the display device is realized, and debugging of the display device is completed. Therefore, the method can avoid the step of manually determining the cascading sequence of different display module units or performing multiple debugging attempts by a debugging person in the debugging process, reduce the professional technical requirements of the debugging person, reduce the time required by debugging and improve the debugging efficiency of the display device.
According to the technical scheme, the test data are sequentially grouped and marked according to the initial configuration parameters of the display module units to form at least two test picture data set units, then the at least two test picture data set units are output to the display module units for display, so that the display module can display the marks, the cascading sequence of different display module units is determined according to the marks, then the initial configuration parameters are updated according to the marks of the display module units, and when the different display module units acquire the data later, the data corresponding to the cascading sequence can be directly acquired according to the updated configuration parameters, normal display of the display device is realized, and debugging of the display device is completed. Therefore, the method can avoid the step of manually determining the cascading sequence of different display module units or performing multiple debugging attempts by a debugging person in the debugging process, reduce the professional technical requirements of the debugging person, reduce the time required by debugging and improve the debugging efficiency of the display device.
Fig. 4 is a flow chart of another method for debugging a display device according to an embodiment of the present invention, as shown in fig. 4, the method includes:
s210, determining the data range of each test picture data group unit according to the resolution ratio of the display module unit, and caching;
the data range of the test picture data set unit is the test picture data amount contained in the test picture data set unit. When the display module unit comprises a display module, the resolution of the display module unit is the resolution of the display module. When the display module unit includes at least two display modules, the resolution of the display module unit is the sum of the resolutions of the at least two display modules. The number of pixels respectively provided in the row direction and the column direction of the display module unit can be determined by the resolution of the display module unit, so that the number of pixel data required for each display module unit can be determined. Then cutting the test data according to the pixel data quantity required by each display module unit, so that the test data quantity of each block can be matched with the pixel data quantity required by the corresponding display module unit, and the display module units can be normally displayed according to the test picture data group units in the subsequent display process. And then caching the data in the test picture data group unit so as to facilitate the subsequent call of the data in the test picture data group unit according to the cache address.
S220, sequentially determining the cache address of each test picture data set unit according to the data set count value;
the data set counting value may be a value obtained by counting the test picture data set units by the data set counting module. The data set count values may be counted sequentially starting from 0, for example, the data set count values may be 0, 1, 2, 3 … … sequentially. When the data group counting module counts, different data group counting values can correspond to cache addresses of different test picture data group units. After the data set count value is determined, the buffer address of each test picture data set unit may be sequentially determined according to the data set count value.
Optionally, determining the buffer address of each test picture data group unit in turn according to the data group count value includes:
and determining the buffer address of the test picture data group unit corresponding to the data group count value according to the data group configuration table.
The initial configuration parameters of the display module may include a data set configuration table. The data set configuration table is used for representing the mapping relation between the data set count value and the cache address of the test picture data set unit. After the data set count value is determined, the buffer address of the test picture data set unit mapped by the value in the data set configuration table can be determined according to the data set count value so as to determine the buffer address of the test picture data unit. For example, the data group count value may be cached in the data group configuration table as a cache address of the test picture data group unit. When the group count value is counted from 0 in sequence, the buffer addresses of the test picture group units may be determined according to the order.
In addition, the data set configuration table may be used to characterize the mapping relationship between the physical interface of the debugging device of the display device and the address of the test picture data set unit, and when the test picture data set unit is output, the data set configuration table may be output according to the mapping relationship between the data set configuration table and the physical interface. For example, the debugging device of the display device may include 32 physical interfaces, each physical interface may output one test picture data set unit, and the mapping relationship between the physical interfaces and the test picture data set units is stored in the data set configuration table, and when different test picture data set units are output, the corresponding physical interfaces may be used for outputting.
S230, ordering at least two test picture data set units according to the cache addresses of the test picture data set units;
after determining the buffer address of the test picture data unit, the test picture data unit may be ordered according to the buffer address sequence of the test picture data unit. For example, when the buffer addresses of the test picture data group units are sequentially 1, 2, 3, and 4 … …, it may be determined that the sequence of the test picture data group units is sequentially a test picture data group unit corresponding to the buffer address of 1, a test picture data group unit corresponding to the buffer address of 2, a test picture data group unit corresponding to the buffer address of 3, and a test picture data group unit … … corresponding to the buffer address of 4.
S240, labeling according to the sequence of the test picture data group units.
Wherein, after determining the sequence of the test picture data set units, the sequence of the test picture data set units can be directly used as the sequence of the labels to realize the labels of the test picture data set units. For example, the order of the test screen data set units may be sequentially 1, 2, 3, and 4 … …, and it may be determined that the test screen data set units are sequentially numbered G1-1, G2-1, G3-1, and G4-1.
S250, outputting at least two test picture data set units to a display module unit for display;
and S260, updating initial configuration parameters according to the labels of the display module units, and completing the debugging of the display device.
On the basis of the technical schemes, when at least one display module unit comprises at least two display modules, the at least two display modules are connected in cascade. The test picture data set unit corresponding to the display module unit comprises at least two test picture data sets. Each test picture data group corresponds to one display module and is used for providing test picture data for the corresponding display module, so that the display module can normally display according to the test picture data and display labels according to label data in the test picture data. When at least one display module unit comprises at least two display modules, at least two display modules in the display module units can be ordered when different display module units are ordered, so that each display module unit can normally display. Fig. 5 is a schematic structural diagram of a display device according to an embodiment of the present invention through receiving card debugging. As shown in fig. 5, the receiving card has a display device integrated therein. The receiving card is provided with N data interfaces, namely a data interface 1, a data interface 2, a data interface 3 and a … … data interface N-1 and a data interface N, and the display device comprises 5 display module units, namely a display module unit 1, a display module unit 2, a display module unit 3, a display module unit 4 and a display module unit 5. Wherein the display module unit 1 and the display module unit 3 are respectively provided with two display modules, and the other display module units comprise a display module. When the display module unit 1 receives the test picture data set unit provided by the data interface 1, the test picture data set unit provided by the data interface 1 comprises two groups of test picture data sets, and the test picture data are provided for two display modules in the display module unit 1 respectively. Similarly, when the display module unit 2 receives the test frame data set unit provided by the data interface 2, the test frame data set unit provided by the data interface 2 includes a set of test frame data sets … …, and so on.
Fig. 6 is a flowchart of another method for debugging a display device according to an embodiment of the present invention, as shown in fig. 6, where the method includes:
s310, determining the data range of each test picture data group unit according to the resolution ratio of the display module unit, and caching;
s320, sequentially determining the cache address of each test picture data set according to the cascade count value of the display module;
the display module cascading counting value can be a value obtained by counting the cascading number of the display module units by the display module cascading counting module. The display module cascade count value may be counted sequentially from 1, for example, the display module cascade count value may be sequentially 1, 2, 3 and … …. The display module cascade count value may be used to characterize the number of display modules cascade in one display module unit. When the display module cascade counting module counts, different display module cascade counting values can correspond to cache addresses of different test picture data sets. After determining the cascade count value of the display module, the buffer address of each test picture data set in the same test picture data set unit can be determined in sequence according to the cascade count value of the display module.
It should be noted that, the buffer address of each test picture data set in the same test picture data set unit is a sub-address in the buffer address of the test picture data set unit.
S330, ordering and marking at least two test picture data sets according to the cache addresses of the test picture data sets.
After determining the buffer addresses of different test picture data sets in the same test picture data set unit, the test picture data sets may be ordered according to the buffer addresses of the test picture data sets. Illustratively, when the buffer address of the first test picture data set unit is 1, the test picture data set unit includes two test picture data sets, the buffer addresses of the two test picture data sets may be 1.1 and 1.2. At this time, it may be determined that the order of the two test picture data sets is sequentially a test picture data set corresponding to an address of 1.1 and a test picture data set corresponding to a buffer address of 1.2. After determining the order of the test screen data sets, the order of the test screen data sets may be referred to as the order of the labels to achieve the labels of the test screen data sets. For example, the order of the test screen data set units may be sequentially 1, 2, 3, and 4 … …, and it may be determined that the test screen data set units are sequentially numbered G1-1, G2-1, G3-1, and G4-1. When the first test picture data set unit comprises two test picture data sets and the order of the at least two test picture data sets is 1.1 and 1.2, it may be determined that the labels of the at least two test picture data set units are G1-1.1 and G1-1.2 in order.
S340, ordering at least two test picture data set units according to the cache addresses of the test picture data set units;
s350, labeling according to the sequence of the test picture data group units.
S360, outputting at least two test picture data set units to a display module unit for display;
and S370, updating initial configuration parameters according to the labels of the display module units, and completing debugging of the display device.
On the basis of the above technical solutions, before sequentially determining the buffer address of each test picture data set according to the cascade count value of the display module, the method further includes:
and determining the maximum value of the cascade count value of the display module according to the initial cascade count value of the display module.
The initial configuration reference of the display module may further include an initial cascading count value of the display module. The initial cascading count value of the display module is used as a circulation condition of the display module counting module so as to ensure that when the at least two display module units comprise a plurality of display modules, the cascading display modules in the at least two display module units can be respectively counted to realize the ordering of the test picture data sets corresponding to the at least two display module units. When the count value of the display module cascade counting module is increased to the initial cascade count value of the real module, the display module cascade counting module starts to circularly count again from 0. The initial cascading count value of the display modules can be set according to the number of the display modules which can be matched by the debugging device of the display device, namely, the initial cascading count value of the display modules can be set according to the number of the display modules which can be matched by the receiving card, and the display module is not limited herein.
In addition, the debugging device of the display device further comprises a configuration parameter analysis module and a basic parameter module. After the debugging device of the display device receives the configuration parameters sent by the sending card, the configuration parameter analysis module analyzes the configuration parameters and outputs the configuration parameters to the basic parameter module, and the basic parameter module can determine the initial cascading count value of the display module and output the initial cascading count value of the display module to the display module counting module, so that the display module counting module can take the initial cascading count value of the display module as a circulation condition.
On the basis of the above technical solutions, after forming at least two test picture data set units, the method further includes:
and configuring the output sequence of at least two test picture data set units according to the cascade sequence configuration table.
The initial configuration parameters of the display module may include a cascade sequence configuration table. The cascade sequence configuration table is used for representing the mapping relation between the sequence of the test picture data set units and the cascade sequence of different display module units. After determining the sequence of the test picture data set units, the display module units corresponding to the test picture data set units can be determined according to the cascade sequence configuration table, and the display module units are cascade-connected, so that the output sequence of the test picture data set units can be determined according to the cascade sequence configuration table. For example, when the display device includes a plurality of display module units, in the cascade sequence configuration table, when the test screen data set units with the sequences of 1, 2, and 3 … … are mapped to the display module units with the cascade sequences of 3, 1, and 2, it may be determined according to the cascade sequence configuration table that the output sequence of the test screen data set units is the test screen data set unit with the sequence of 2 corresponding to the display module unit with the cascade sequence of 1, the test screen data set unit with the sequence of 3 corresponding to the display module unit with the cascade sequence of 2, and the test screen data set unit with the sequence of 1 corresponding to the display module unit with the cascade sequence of 3.
Based on the above technical solutions, outputting at least two test frame data sets to the display module unit for display, including:
and sequentially outputting at least two test picture data set units to the display module unit according to the output sequence for display.
After determining the output sequence of the at least two test picture data set units, the test picture data set units can be sequentially output according to the output sequence of the at least two test picture data set units, so that the test picture data set units can be matched with the display module unit, and the display module unit can display normally. Meanwhile, the test picture data group unit is provided with label data, and when the display module unit displays the label data, the label data can be displayed.
Based on the above technical solutions, updating initial configuration parameters according to the labels of the display module units to complete the debugging of the display device, including:
and updating the cascade sequence configuration table according to the label of the display module unit.
After the display module units display the labels, the cascade sequence of different display module units can be determined according to the labels. At this time, a mapping relation between the label and the sequence of the test picture data set unit can be established in the upper computer, a mapping relation between the cascading sequence of the display module unit and the sequence of the test picture data set unit is determined, and the cascading sequence configuration table is updated. And the test picture data set unit is output by the debugging device of the display device according to the updated cascade sequence configuration table, so that the test picture data set unit can be matched with the display module unit, and the display device is debugged.
It should be noted that, when the initial configuration parameter includes the display module cascading count value, the display module initial cascading count value can be updated according to the display number of the display module units, so as to avoid abnormal display caused by overlarge display module initial cascading count value.
