Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 3, the LED display screen system 10 of the present embodiment includes a transmitting card 11, a plurality of cascaded data distributors 13, and a plurality of strings of LED display unit boards 15. Each data distributor 13 is connected with a plurality of strings of LED display unit panels 15, and each string of LED display unit panels 15 has one LED display unit panel 150 or a plurality of cascaded LED display unit panels 150 as shown in fig. 3. The single LED display unit board 150 (or referred to as an LED display unit) includes an LED lamp panel 151 and a scan card module 153 fixedly disposed on the LED lamp panel 151, wherein the scan card module 153 is generally designed with a programmable logic device, such as an FPGA chip, responsible for data conversion and gray scale control to provide data and control signals required for display to the LED lamp panel 151. More specifically, as shown in fig. 4a and 4b, the LED lamp panel 151 includes a circuit board 1511, a plurality of RGB three-color LEDs 1513 disposed on the front surface of the circuit board 1511, and a plurality of net ports 1515 disposed on the back surface of the circuit board 1511; of course, an LED driving circuit is also disposed on the back side of the circuit board 1511, which is a well-known technology and will not be described herein. Moreover, in fig. 4a, the scan card module 153 is directly integrated on the back of the circuit board 1511 (i.e. the scan card module 153, the LED1513 and the network port 1515 are disposed on the same circuit board 1511) and electrically connected to the plurality of network ports 1515; in fig. 4b, the scan card module 153 is separately disposed from the LED lamp panel 151 and fixed on the back of the circuit board 1511 to form an electrical connection with a plurality of ports 1515, for example, the scan card module 153 is disposed on a single circuit board and fixedly connected on the back of the circuit board 1511 by pin/socket arrangement. In other embodiments, the plurality of ports 1515 and the scan card module 153 may be disposed on the same circuit board separated from the circuit board 1511 of the LED lamp panel 151, and then the circuit board is fixedly connected to the circuit board 1511 of the LED lamp panel 151, for example, the circuit board is fixedly connected by pin arrangement/female arrangement, that is, the scan card module 153 and the LED lamp panel 151 are designed as a two-layer circuit board.
As described above, in this embodiment, since each LED lamp panel 151 is provided with a plurality of net ports 1515, each LED display unit board 150 in the same string of LED display unit boards 15 may be cascaded together through a net wire, for example, a hundred mega net wire, and connected to the corresponding data distributor 13. Thus, the first-stage LED display unit board 150 can utilize one of the network ports 1515 of the LED lamp panel 151 to receive the display signal from the data distributor 13 and send the display signal to the scanning card module 153 thereof to capture the display signal thereof and perform data conversion and gray scale control processing to drive the LED1513 thereof for display, while the display signal which does not belong to the first-stage LED display unit board 150 can be sent to the next-stage LED display unit board 150 through the other network port 1515; the signal processing process of the rear-stage LED display unit board 150 is similar to that of the first-stage LED display unit board 150, and therefore, the description thereof is omitted.
Referring again to fig. 3, each data distributor 13 is cascaded to the transmitting card 11, for example, via a network cable, such as a gigabit network cable. Of course, for some LED display screen systems without a transmitting card, the cascaded data distributor 13 may also be directly connected to an upper computer such as a PC through a network cable to obtain a video display signal. In addition, it should be noted that the number of the data distributors 13 is not limited to a plurality, and the specific number may be determined according to actual needs, for example, for a case that the size of the LED display screen is relatively small, only one data distributor 13 may be provided.
The specific structure of the data distributor 13 according to the embodiment of the present invention will be described in detail with reference to fig. 5a and 5 b.
As shown in fig. 5a, the data distributor 13 includes two master transceiving network ports (MRX1, MTX1), (MRX2, MTX2), a plurality of slave transceiving network ports (SRX1, STX1), (SRX2, STX2), (SRX3, STX3), and (SRX4, STX4), a configuration module 131, and a data distribution module 133.
Among them, the main transceiving network ports (MRX1, MTX1), (MRX2, MTX2) are used for receiving the display data provided by the transmitting card 11 and transmitting the display data not belonging to itself to the next-stage data distributor 13 under the processing of the data distribution module 133. The slave network ports (SRX1, STX1), (SRX2, STX2), (SRX3, STX3) and (SRX4, STX4) are used to forward display data to each string of LED display cell boards 15 connected to the data distributor 13. The configuration module 131 is configured to record and provide configuration information such as sub-tape information of each slave network interface (SRX1, STX1), (SRX2, STX2), (SRX3, STX3), and (SRX4, STX4), and total tape information of the data distributor 13 to which the sub-tape information belongs. The data distribution module 133 is configured to retrieve display data belonging to its own from the display data of the front end, for example, the transmitting card 11, according to the configuration information of the configuration module 131, and distribute the retrieved display data belonging to its own to each slave network port, for example, (SRX1, STX1), (SRX2, STX2), (SRX3, STX3), (SRX4, STX 4). In addition, the slave transceiving ports (SRX1, STX1), (SRX2, STX2), (SRX3, STX3), (SRX4, STX4) can also transmit the information transmitted back by each string of LED display unit boards 15 to the upper computer through the master transceiving port and the transmission card 11, and accordingly, as shown in fig. 5b, the data distributor 13 is designed with a data collection module 135 for collecting the transmitted back information from each string of LED display unit boards 15 of each slave transceiving port (SRX1, STX1), (SRX2, STX2), (SRX3, STX3), and (SRX4, STX4) and the transmitted back information of each string of LED display unit boards 15 transmitted by the next-stage data distributor 13 through the master transceiving ports such as (MRX2, MTX2), and transmit the collected back information to the upper computer through the master transceiving ports such as (MRX1, MTX1), and the transmission card 11. Here, the feedback information of each string of LED display unit panels 15 includes, for example, the result of point inspection, temperature and humidity, smoke, power status, fan status, and whether the door is closed.
Referring to fig. 3 and 5, after the system architecture of fig. 3 is built, the sending card 11 may distribute addresses of a plurality of cascaded (or called concatenated) data distributors 13, and the distributed information issues, through the master transceiving network port, partial load information including a start position of a load of each data distributor 13, a size of a load area, and the like, and a start position of a load of each slave transceiving network port, a size of a load area, and the like; the issued information may be configured by software and stored in the configuration module 131 of each data distributor 13, or issued in real time in the form of data packets and analyzed in real time by the configuration module 131 of each data distributor 13.
The data distributor 13 calculates the information such as the loading start position and the loading area size of the scan card module 153 in each LED display unit board 150 according to the loading start position and the loading area size of each slave transceiver network port and the scan card module information corresponding to the slave transceiver network port, and sends the calculated information to the corresponding scan card module 13. The information of the scanning card module corresponding to the slave transceiving network port can be obtained by the interaction between the data distributor 13 and the scanning card module 153, or can be stored in the configuration module 131 of the data distributor 13 by being issued by software. In the case where the slave transmission/reception ports are not loaded, the corresponding slave transmission/reception port may output no relevant information or output arbitrary information.
It should be noted that the master transceiving network port and the slave transceiving network port may also be replaced by other transceiving interfaces, such as an optical interface (or called an optical fiber interface) or other high-speed interfaces.
In addition, from the description related to the data distributor 13 of the above embodiment, a display control method may be summarized, which includes, for example: receiving externally input display data, for example, receiving externally input display data through an electrical port such as a network port or other interfaces such as an optical port; acquiring first display data belonging to the display data according to the total load information; and segmenting the first display data according to the sub-tape loading information to obtain at least one second display data. Further, it may further comprise the steps of: and outputting the display data which does not belong to the display data to the outside without dividing the display data. Furthermore, the display control method may further include the steps of: and receiving an externally input data packet of the load information in real time and analyzing the data packet of the load information to obtain the total load information and the sub-load information.
In summary, the above embodiment of the present invention can complete transparent transmission of front-end data, such as data of a sending card, and division and forwarding of the sending card data to data of a scanning card by adding a data distributor, so as to effectively solve the problem of loading after the scanning card and the LED lamp panel are combined into one in the prior art.
