All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
First embodiment
Please refer to fig. 1, which is a flowchart illustrating a screen matching method according to a first embodiment of the present invention. The screen configuration method of the embodiment comprises the following steps:
s11: automatically detecting which connecting ports of a plurality of connecting ports are connected with a target display screen to obtain a plurality of target connecting ports with the target display screen in the plurality of connecting ports; and
s13: and configuring a loading area of each target connection port on the target display screen according to the positions and the number of the target connection ports.
To facilitate understanding of the screen matching method of the present embodiment, step S11 and step S13 of the present embodiment are described in detail below with reference to fig. 2.
Fig. 2 shows a display system 20 suitable for performing steps S11 and S13. As shown in fig. 2, the display system 20 includes: a display screen controller 21 and a display screen 23 connected to the display screen controller 21. The display panel controller 21 includes a main control circuit 211 and a plurality of connection ports 213 connected to the main control circuit 211, and the main control circuit 211 further includes, for example, a processing circuit 2111 and a physical layer transceiver 2113 connected to the processing circuit 2111, and each connection port 213 of the display panel controller 21 is connected to the processing circuit 2111 through the physical layer transceiver 2113. The processing circuit 2111 includes, for example, a programmable logic device (e.g., an FPGA device) and a microcontroller (e.g., an MCU) connected to the programmable logic device. The physical layer transceiver 2113 includes, for example, a plurality of PHY chips to be connected to the respective connection ports 213 in a one-to-one correspondence. In addition, taking each connection port 213 as a network port as an example, a network transformer may be additionally disposed between the physical layer transceiver 2113 and each connection port 213 in order to increase the signal transmission distance. The display screen 23 includes a plurality of splicing units 231 arranged in rows and columns; in an application where the display screen 23 is an LED display screen, each splicing unit 231 is, for example, an LED box body, and is configured with a display control card, such as a receiving card, and an LED lamp panel connected to the display control card. In addition, the individual tile cells 231 in the same row are cascaded together, for example, the display control cards in the individual tile cells 231 are cascaded together through a network cable.
In view of the above, when configuring the screen, the user performs the following operation according to the connection constraint condition between the display screen 23 and the display screen controller 21: one connection port 213 is connected to only one row of the splicing units 231 and preferably, the sequence of the rows of the splicing units connected to each connection port 213 in the column direction is the same as the arrangement sequence of each connection port 213 on the display screen controller 21.
Then, the processing circuit 2111 in the main control circuit 211 on the display screen controller 21 automatically detects the status registers of the PHY chips in the physical layer transceiver 2113 to obtain the LINK status of the connection ports 213 connected to the PHY chips, and can determine which connection ports 213 have been connected to the display screen 23 as the target connection ports 213 by obtaining the LINK status, so as to know the positions and the number of the target connection ports 213 connected to the display screen 23. In addition, the resolution of each tile connected to the target port 213 can be obtained by reading a specific register on each tile connected (loaded) to the target port 213.
Then, the loading area of the target connection port 213 on the display screen 23 can be configured according to the position and number of each target connection port 213 connected to the display screen 23. Taking fig. 2 as an example, assuming that four connection ports 213 are automatically detected to be connected to the display 23, the following ways can be adopted to configure the loaded areas of the four target connection ports 213 on the display 23:
mode (1): equally dividing the resolution of the display screen 23 into four parts in the column direction to obtain four resolution partitions, and then respectively using the four resolution partitions as loading areas of the four target connection ports 213 on the display screen 23 according to the positions of the four target connection ports 213 on the display screen controller 21; the method is mainly applied to the situation that the widths of all the splicing units of the display screen 23 in the row direction are equal, and the width of all the splicing units in the row direction is not limited;
mode (2): the main control circuit 211 on the display screen controller 21 reads the width of the corresponding splicing unit row on the display screen 23 in the column direction through the four target connection ports 213 connected to the display screen 23, and since the widths of the splicing units in the same row in the column direction are equal, it is only necessary to read the width of the first splicing unit in each row of splicing units in the column direction (expressed by the number of pixels), and then cut the resolution of the display screen 23 into four parts by combining the positions of the four target connection ports 213 and the width of the actually loaded splicing unit row in the column direction, so as to obtain four resolution partitions, and then take the four resolution partitions as the loaded areas of the four target connection ports 213 on the display screen 23, respectively.
Generally, the loaded area of the connection port 213 is expressed using information such as the start coordinate, width, and height of the area on the display screen 23.
As can be seen from the above, the first embodiment of the present invention pre-restricts the user from loading each row of the splicing units 231 of the display screen 23 through only one connection port 213 during connection, obtains the target connection port (i.e., the connection port connected to the display screen 23) by automatically detecting the connection status (LINK status) of each connection port 213 of the display screen controller 21, and then configures the loading area according to the position and number of the target connection ports 213, so as to implement automatic screen configuration. It should be noted that the number of the connection ports 213 of the display screen controller 21 shown in fig. 2 is four for example only and is not intended to limit the present invention.
Second embodiment
Referring to fig. 3, a display system 30 capable of performing the screen matching method shown in fig. 1 according to a second embodiment of the present invention is shown. As shown in fig. 3, the display system 30 includes: a display screen controller 31 and a display screen 33 connected to the display screen controller 31. The display panel controller 31 includes a main control circuit 311 and a plurality of connection ports 313 connected to the main control circuit 311, and the main control circuit 311 further includes, for example, a processing circuit 3111, a plurality of phy transceivers 3112 connected to the processing circuit 3111, a plurality of data interfaces 3113 respectively connected to the phy transceivers 3112, and a port expansion circuit 3114 connected to each data interface. Each connection port 313 is connected to the output side of the port expansion circuit 3114. The processing circuit 3111 includes, for example, a programmable logic device (e.g., an FPGA device) and a microcontroller, such as an MCU, connected to the programmable logic device. Each physical layer transceiver 3112 is, for example, a PHY chip, such as an ethernet PHY chip. Each data interface 3113 is an interface based on an ethernet protocol, for example. More specifically, taking fig. 3 as an example, four data interfaces 3113 are connected to the input side of the port expansion circuit 3114, and accordingly, the input side of the port expansion circuit 3114 includes, for example, four port expansion circuit units (not shown in fig. 3), and each port expansion circuit unit is, for example, a 1-in-8 expander or a 1-in-4 expander, so that the four data interfaces 3113 can be expanded into 32 or 16 connection ports 313. In addition, each port expansion circuit unit typically includes a programmable logic device such as an FPGA device and a plurality of PHY chips such as ethernet PHY chips connected to the programmable logic device.
As mentioned above, the display screen 33 includes a plurality of splicing units 331 arranged in rows and columns; in an application where the display screen 33 is an LED display screen, each of the splicing units 331 is, for example, an LED box body configured with a display control card, such as a receiving card, and an LED lamp panel connected to the display control card. In addition, the splicing units 331 located in the same column are cascaded together, for example, the display control cards in the splicing units 331 are cascaded together through a network cable.
In summary, when screen configuration is performed, according to the connection constraint condition between the display screen 33 and the display screen controller 31: one connection port 313 is connected to only one column of the mosaic units 331 carried on the tape, and preferably, the sequence of the columns of the mosaic units connected to each connection port 313 in the row direction is consistent with the arrangement sequence of each connection port 313 on the display screen controller 31.
Thereafter, the port expansion circuit 3114 in the main control circuit 311 on the display screen controller 31 automatically detects the LINK status of each connection port 313 (e.g., by reading a status register of a PHY chip thereon) to obtain which connection ports 313 are the target connection ports 313 connected to the display screen 33. In addition, the processing circuit 3111 may also automatically detect the status register of each phy transceiver 3112 to obtain the LINK status of the data interface 3113 connected to each phy transceiver 3112, and determine which connection port 313 and data interface 3113 are connected to the display 33 by obtaining the LINK status of each connection port 313 and the LINK status of the data interface 3113, so as to know the location and number of the connection port 313 and data interface 3113 connected to the display 33. In addition, a specific register on each tile connected (loaded) by the target connection port 313 can be read to obtain the resolution of each tile connected by the target connection port 313.
Then, the loading area of the target connection port 313 on the display screen 33 can be configured according to the position and number of the target connection port 313 and the data interface 3113 which are connected to the display screen 33. Taking fig. 3 as an example, assuming that four data interfaces 3113 are connected to the display 33 and eight connection ports 313 extended from each data interface 3113 by the port extension circuit 3114 are also connected to the display 33, configuring the loading areas of thirty-two target connection ports 313 on the display 33 may be performed in the following manners:
mode (1): the processing circuit 3111 in the main control circuit 311 equally divides the resolution of the display screen 33 into four resolution partitions in the row direction, then uses the four resolution partitions as the loaded areas of the four data interfaces 3113 on the display screen 33 according to the positions of the four data interfaces 3113, and then performs a second division on the loaded areas of each data interface 3113 by the port expansion circuit 3114, for example, when a certain data interface 3113 expands eight connection ports 313 through the port expansion circuit 3114, the loaded areas of the data interface 3113 are equally divided into eight by the port expansion circuit 3114 to obtain eight resolution partitions, which are used as the loaded areas of the eight connection ports 313 expanded by the data interface 3113; the method is mainly applied to the situation that the widths of all the splicing units of the display screen 33 in the row direction are equal, and the width of all the splicing units in the column direction is not limited;
mode (2): the port expansion circuit 3114 in the main control circuit 311 in the display screen controller 31 reads the width of the corresponding splicing unit column on the display screen 33 in the row direction through each connection port 313 connected to the display screen 33, and since the widths of the splicing units in the same column in the row direction are equal, it is only necessary to read the width (expressed by the number of pixels) of the first splicing unit in each column of splicing units in the row direction and transmit the width to the processing circuit 3111, and then the resolution of the display screen 33 is cut into four parts by combining the positions of the four data interfaces 3113 connected to the display screen 33 and the width of the actually loaded splicing unit column in the row direction, so as to obtain four resolution partitions, and then the four resolution partitions are respectively used as the loaded areas of the four data interfaces 3113 on the display screen 33; then, the port expansion circuit 3114 performs a second division on the loaded area of each data interface 3113, for example, when the display screen 33 is connected to all the eight connection ports 313 of a certain data interface 3113 expanded by the port expansion circuit 3114, the port expansion circuit 3114 divides the loaded area of the data interface 3113 into eight parts to obtain eight resolution sub-partitions, which are respectively used as the loaded areas of the eight connection ports 313 expanded by the data interface 3113.
Generally, the loaded area of the connection port 313 is characterized by information such as the start coordinate, width and height of the area on the display screen 33.
As can be seen from the above, the second embodiment of the present invention pre-restricts the user from loading each row of the splicing units 331 of the display screen 33 through only one connection port 313 during the connection, obtains the target connection port 313 (i.e., the connection port 313 connected to the display screen 33) by automatically detecting the connection status (LINK status) of each connection port 313 of the display screen controller 31, and then configures the loading area according to the position and number of the target connection ports 313, so as to implement the automatic screen configuration. In addition, it should be noted that, in the image display control process after the screen is configured, the still image data or the video image data input to the display screen controller 31 is first cut in the processing circuit 3111, and is second cut in the port expansion circuit 3113 after the first cut, and then is output to the display screen 33 through the target connection port 313 for image display.
It should be noted that in the second embodiment of the present invention, if the number of the data interfaces 3113 of the display screen controller 31 is enough to connect each of the tiled cell columns of the on-board display screen 33, the port expansion circuit 3114 may also be omitted.

More specifically, the physical layer transceiver 41113 includes, for example, multiple PHY chips such as ethernet PHY chips to connect to the respective data interfaces 4113, and the respective data interfaces 4113 are, for example, ports; in addition, a network transformer may be further disposed between each data interface 4113 and the physical layer transceiver 41113 to increase the signal transmission distance.

In view of the above, when screen configuration is performed, according to the connection constraint condition between the display screen 43 and the display screen control system 41: one connection port 4131 is connected to only one column of the tile units 431 and preferably, the sequence of the columns of the tile units connected to each connection port 4131 in the row direction is the same as the arrangement sequence of the connection ports 4131 in the display control system 41.
Thereafter, the port expander 413 automatically detects the LINK status of each connection port 4131 to acquire which connection ports 4131 are the target connection ports 4131 connected to the display screen 43. In addition, the processing circuit 41111 in the main control circuit 4111 of the display panel controller 411 may also automatically detect the status register of the physical layer transceiver 41113 to obtain the LINK status of each data interface 4113 connected to the physical layer transceiver 41113, and determine which connection ports 4131 and which data interfaces 4113 are already connected to the display panel 43 by obtaining the LINK status of each connection port 4131 and data interface 4113, so as to know the locations and the numbers of the target connection ports 4131 and data interfaces 4113 connected to the display panel 43. In addition, a specific register on each tile connected (loaded) by the target connection port 4131 can be read to obtain the resolution of each tile connected by the target connection port 4131.
Then, the loading area of the target connection port 4131 on the display screen 43 can be configured according to the position and the number of the target connection port 4131 and the data interface 4113 which are already connected to the display screen 43. Taking fig. 4 as an example, assuming that four data interfaces 4113 are automatically detected to be connected to the display 43 and eight connection ports 4131 expanded by each data interface 4113 via the port expander 413 are also connected to the display 43, configuring the loaded area of thirty-two target connection ports 4131 on the display 43 may be implemented in the following ways:
mode (1): the processing circuit 41111 in the main control circuit 4111 of the display controller 411 equally divides the resolution of the display screen 43 into four partitions in the row direction to obtain four resolution partitions, then according to the positions of the four data interfaces 4113, the four resolution partitions are respectively used as the loaded areas of the four data interfaces 4113 on the display screen 43, and then the port expander 413 performs a second division on the loaded area of each data interface 4113, for example, when a certain data interface 4113 expands eight connection ports 4131 via the port expander 413, the port expander 413 equally divides the loaded area of the data interface 4113 into eight partitions to obtain eight resolution sub-partitions, which are respectively used as the loaded areas of the eight connection ports 4131 corresponding to the data interface 4113; the method is mainly applied to the situation that the widths of all the splicing units of the display screen 43 in the row direction are equal, and the width of all the splicing units in the column direction is not limited;
mode (2): the port expander 413 reads the width of the corresponding splicing unit column on the display screen 43 in the row direction through each connection port 4131 connected to the display screen 43, and since the widths of the splicing units in the same column in the row direction are equal, it may only need to read the width (expressed by the number of pixels) of the first splicing unit in each column of splicing units in the row direction and transmit the width to the processing circuit 41111 in the main control circuit 4111 on the display screen controller 411, and then cut the resolution of the display screen 43 into four parts by combining the positions of the four data interfaces 4113 connected to the display screen 43 and the width of the actually loaded splicing unit column in the row direction, so as to obtain four resolution partitions, and then use the four resolution partitions as the loaded areas of the four data interfaces 4113 on the display screen 43, respectively; then, the port expander 413 performs a second cutting on the loaded area of each data interface 4113, for example, when all the eight connection ports 4131 expanded by a certain data interface 4113 through the port expander 413 are connected to the display screen 43, the port expander 413 cuts the loaded area of the data interface 4113 into eight parts to obtain eight resolution sub-partitions, which are respectively used as the loaded areas of the eight connection ports 4131 corresponding to the data interface 4113.
Generally, the loaded area of the connection port 4131 is characterized using information such as the starting coordinates, width and height of the area on the display screen 43.
As can be seen from the above, the third embodiment of the present invention pre-restricts the user from limiting each row of the splicing units 431 of the display screen 43 to be loaded by only one connection port 4131 during the connection, obtains the target connection port 4131 (i.e., the connection port 4131 connected to the display screen 43) by automatically detecting the connection status (LINK status) of each connection port 4131 of the display screen control system 41, and then configures the loading area according to the position and number of the target connection port 4131, so as to implement the automatic screen configuration. In addition, in the process of image display control after screen configuration, for the still image data or video image data input to the display screen controller 41, a first cutting is performed in the processing circuit 41111 in the main control circuit 4111 of the display screen controller 411, and after the first cutting, the still image data or video image data is output to the port expander 413 for a second cutting, and then the still image data or video image data is output to the display screen 43 through the target connection port 4131 for image display.
It should be noted that, in the third embodiment of the present invention, if the number of the data interfaces 4113 of the display screen controller 411 is enough to connect the columns of the tiled display screens 43, the port extender 4113 may not be externally connected. Still alternatively, only a part of the data interfaces 4113 may be port-extended by using a port extender according to actual needs, in which case, the remaining non-extended data interfaces 4113 may be directly used as the target connection port connected to the display screen 43.
