As shown in fig. 1, an embodiment of the present application provides a display system, including:
a display device 1 provided with a first communication port 3 for receiving a first signal and a second communication port 4 for receiving a second signal; and
a data transmission line 2 having a first connector 5 matching the first communication port 3 and a second connector 6 matching the second communication port 4, the data transmission line 2 for connecting the display data generation device 7 and the display device 1 through the first connector 5 and the second connector 6, the data transmission line 2 processing data output from the display data generation device 7 into a first signal if the first connector 5 is connected to the first communication port 3 so that the display device 1 can display the data based on the first signal; if the second connector 6 is connected to the second communication port 4, the data transmission line 2 processes the data output from the display data generation device 7 into a second signal so that the display device 1 can display the data based on the second signal.
The display system in the embodiment of the present application, by providing two different communication ports on the display device 1, and simultaneously, a data transmission line 2 with two connectors respectively matched with the two communication ports is arranged in a matching way, so that the display device 1 can be connected with two display data generating devices 7 respectively having different types of communication ports through only one data transmission line 2, without using two different data transmission lines 2 for connection, that is, it is not necessary to provide a matching data transmission line 2 between the display device 1 and each display data generating device 7 for connection, thereby simplifying the complexity of system components, the installation cost and the connection operation steps, improving the generalization of the display device 1 in the use of users, namely, the adaptation range of the display device 1 in application is improved, so that the use of the user is facilitated, and the use experience of the user is improved.
Specifically, the display data generation device 7 in this embodiment has a third communication port 8 that is the same as the first communication port 3 or the second communication port 4, the first connector 5 and the second connector 6 are respectively provided at two opposite ends of the data transmission line 2, and the data transmission line 2 is connected to the display data generation device 7 by the connection of the first connector 5 or the second connector 6 to the third communication port 8. For example, in the present embodiment, the first communication port 3 is a DP interface, the second communication port 4 is an HDMI interface, and the third communication port 8 on the display data generation apparatus 7 is a DP interface or an HDMI interface. Of course, the first communication port 3 and the second communication port 4 can also be other types of interfaces, such as USB2.0 interface, USB3.0 interface, etc., as well as the third communication port 8. The first connector 5 is a connector matched with a DP interface, and the second connector 6 is a connector matched with an HDMI interface. The reason why the two communication ports are respectively set as the HDMI interface and the DP interface in this embodiment is that, at present, the display device 1 and the display data generation device 7 both set one of them as the communication port, so that it is more universal to adopt the HDMI interface and the DP interface as the communication ports. Of course, if other types of interfaces are more commonly used between the display device 1 and the display data generation device 7 in the future, the settings of the communication ports may be changed accordingly. In addition, the data transmission line 2 in this embodiment may be a single data line, and the two connectors are respectively disposed at two ends of the data transmission line 2, but of course, the data transmission line 2 may also be Y-shaped, that is, a data line with branches, when the data line is a data line with branches such as Y-shaped, the connectors may be disposed in three pairs, one of the connectors is a connector that is matched with the DP interface, and the other two connectors are connectors that are both matched with the HDMI interface. In this embodiment, the data transmission line 2 is taken as an independent and non-branched data line for illustration, when a user wants to connect the display device 1 and the display data generation device 7 through the data transmission line 2, the determination may be performed according to the type of the third communication port 8 of the display data generation device 7, then the connector on the data transmission line 2 matching the third communication port 8 is connected to the port, and then the other connector on the data transmission line 2 is connected to the corresponding port on the display device 1, at this time, the communication connection between the devices is completed, and the display data generation device 7 can transmit the display data to the display device 1 through the data transmission line 2. It should be noted that, when the display device 1 and the display data generating device 7 are connected by the data transmission line 2, the data transmission direction of the data transmission line 2 is fixed, and the data is transmitted from the display data generating device 7 side to the display device 1 side, but not in the reverse direction. That is, although the data transmission line 2 can be connected arbitrarily according to the kind of the communication port of the two devices, once connected, the data transmission direction thereof is only from the display data generation device 7 side to the display device 1 side.
Further, the number of first pins of the first connector 5 on the data transmission line 2 in the present embodiment needs to be greater than or equal to the number of second pins of the second connector 6, wherein the first connector 5 is used for connecting with the first communication port 3 or the second communication port 4. That is, the number of pins of the two connectors needs to be at least equal, because the data transmission line 2 and the corresponding communication port are provided with cores for transmitting data corresponding to the matched connector pins, that is, each pin of the two connectors is used for transmitting data, if the number of pins of the two connectors is not matched and the number of pins of the connector connected to the display device 1 is less than the number of pins of the connector connected to the display data generation device 7, some pins of the display data generation device 7 and the data transmitted by the cores thereof cannot be received by the display device 1, resulting in data loss. Only when the number of pins of the two connectors is equal or the number of pins of the connector connected with the display device 1 is more, it can be ensured that the data output by the display data generation device 7 can be completely received by the display device 1, and the phenomenon of data loss cannot be caused.
Further, in the embodiment of the present application, the plurality of first pins have a first arrangement manner according to the data type transmitted by each first pin, the plurality of second pins have a second arrangement manner according to the data type transmitted by each second pin, and the first arrangement manner matches with the second arrangement manner.
For example, the plurality of first pins are respectively connected with the cores for transmitting different types of data, so that the first arrangement mode of the plurality of first pins is consistent with the arrangement mode of the data types transmitted by the cores connected with the first pins. The second pins are also respectively connected with fiber cores used for transmitting different types of data, so that the second arrangement mode of the second pins is also consistent with the arrangement mode of the data types transmitted by the fiber cores connected with the second pins. The first arrangement mode and the second arrangement mode are set to be matched, so that matching transmission between various types of data and pins of corresponding ports is guaranteed, data can be transmitted successfully, and the phenomenon that messy codes occur in subsequent display due to confusion of the data in the transmission process is avoided.
Specifically, in this embodiment, in the first pins arranged in the first arrangement manner and the second pins arranged in the second arrangement manner, the data types transmitted by the first pins and the second pins corresponding to the positions satisfy the matching condition. And the first pin meeting the matching condition is connected with the second pin.
For example, assume simply that there are four first pins from left to right, the first three pins being used to transfer Data1, Data2, and Data3, respectively, and the fourth pin being connected to ground.
Similarly, based on the above direction, there are four second pins from left to right, the first three of which are used to transmit Data1+, Data2+, Data3+, and the fourth one is connected to ground.
The Data types of Data1, Data2 and Data3 are respectively matched with the Data types of Data1+, Data2+ and Data3+, and the grounding end is matched with the grounding end, so that the four first pins respectively correspond to the four second pins one by one in the sequence from left to right and are connected in a matched manner through fiber cores. When Data1+ sequentially passes through the second pin and the corresponding fiber core to be transmitted to the corresponding first pin, Data1+ can be successfully converted into Data1, and the Data is received by the first communication port 3 and input into the display device 1, and the Data1 is identified and displayed by the display device 1.
As another example, still taking two connectors as HDMI connector and DP connector as examples, the pins of the two connectors can be arranged in the following arrangement manner:
the pins of the HDMI port and the pins of the DP port in the same row have the same data transmission type, and the corresponding pins have the same number, namely the same position, and are connected through the fiber core. For example, the data transmission types of the pin of the HDMI port with the pin number 18 and the pin of the DP port are HPD, that is, Hot Plug Detect, and the like, while for the other pins, for example, the pin of the HDMI port with the pin number 15 and the pin of the DP port, although the data names are different, they are SCL and AUX _ CH _ P, respectively, but the data types are consistent.
Further, as shown in fig. 2, an embodiment of the present application provides a data transmission line at the same time, including:
a first connector to mate with the first communication port;
a second connector matching the second communication port;
wherein if the data transmission line is connected to the display data generation device and the display device through the first connector and the second connector, if the first connector is connected to the first communication port of the display device, the data transmission line processes data output from the display data generation device into a first signal so that the display can display the data based on the first signal; if the second connector is connected with the second communication port of the display device, the data transmission line processes the data output by the display data generation device into a second signal so that the display can display the data based on the second signal.
The data transmission line in the embodiment of the present application is the transmission line in the display system described above, which has all the features described above for the data transmission line, and similarly, the data transmission line described above also has the features of the data transmission line in the embodiment of the present application. That is, by using the data transmission line in the embodiment of the present application, it is also possible to freely connect the display device and the display data generation device having different communication ports, and to implement data conversion and data transmission between the two devices.
Further, the first connector and the second connector of the data transmission line in the embodiment of the present application are both connectors that support at least one same data transmission protocol.
For example, taking the HDMI connector and the DP connector as the first connector and the second connector in this embodiment, respectively, both connectors support the DP + + protocol, so that both connectors can implement data conversion and transmission based on the DP protocol. The reason why the two connectors need to support at least the same data transmission protocol is to ensure that no large difference occurs between the pins of the two connectors and the data transmission types between the pins are at least approximately the same.
Further, the first joint and the second joint in the embodiment of the present application are the same in structure type.
For example, the first connector and the second connector are both male connectors and have protruding electrical connectors to increase the adaptability of the connectors to the communication interface, and simultaneously increase the safety of the connectors and avoid dust accumulation and liquid accumulation to damage the performance of the connectors. Of course, each may be a female connector having an electrical plug-in slot, depending on the configuration of the communication port. Moreover, in this embodiment, preferably set up two joints as male connectors, can also effectively guarantee that two joints all can directly be connected with two equipment respectively, avoid appearing only can a certain joint can directly link to each other with equipment, and another joint can only link to each other with the lead-out wire of another equipment to be connected with another equipment through the lead-out wire, that is, avoid data transmission line 2 in this embodiment to only play the effect of a port extension line.
As shown in fig. 2, an embodiment of the present application also provides a data processing method, including:
the data transmission line obtains display data from the display data generating device;
the data transmission line processes the display data to form a first signal or a second signal which can be recognized and displayed by the display device;

The data processing method in the embodiment of the application is applied to the display system, and the display device and the data transmission line of the display system are the display device and the data transmission line mentioned above. And, similarly, through setting up two different communication ports on the display device, cooperate and set up the data transmission line with two joints that match with two communication ports respectively at the same time, make the display device just can be connected with two kinds of display data generating equipment that have different types of communication ports respectively through a data transmission line, and need not to adopt two kinds of different data transmission lines to connect, namely, need not to be equipped with a data transmission line of matching between display device and every display data generating equipment and realize connecting, the complexity of the system part has been simplified, set up cost and connection operating procedure, the generalization of display device in the use of user has been improved, namely, the adaptation scope of this display device in the application has been improved, so made things convenient for user's use, user's experience of use has been improved.
