Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display data transmission structure and a display device. Background Art

[0002] The display screens in conventional display devices mostly use similar Figure 1 The topology shown is that the sending card and several receiving cards are in a series relationship, and at the same time, one receiving card establishes a connection relationship with multiple display modules. After the receiving card processes the received display data, it obtains the display data required by the display module with which it has a direct connection, and then sends the display data to the corresponding display module for display driving.

[0003] As shown in the topology structure above, because the number of display modules that can be directly connected to a receiving card is limited, when there are more display modules in the display screen, the number of receiving cards will increase accordingly, which will result in device costs. At the same time, the number of display modules directly connected to the receiving card reflects the number of IO interfaces required. Therefore, the more display modules directly connected to the receiving card, the more IO interfaces need to be set, and the system processing cost of the receiving card will also increase accordingly. That is, the topology structure of the conventional display screen has a high cost phenomenon.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0046] The present application proposes a display data transmission structure.

[0047] See Figure 2 In this application, the display data transmission structure includes several display data transmission units. The connection structure between the same component and other components in each display data transmission unit is the same. The components include:

[0048] The receiving card is used to transmit the total display data received through the transceiver port. Multiple display modules connected in series to the same transceiver port of the receiving card are used to extract the target display data from the total display data transmitted by the previous component and then transparently transmit the total display data to the next display module in the series.

[0049] exist Figure 1 Based on the above, the conventional display data transmission topology is described. Figure 1 It can be seen that the conventional display data transmission path is: after the sending card sends the display data to a receiving card connected to it, the receiving card transmits the received display data to the next receiving card connected to it. At the same time, each receiving card is directly connected to 4 display modules. Each receiving card parses and processes the received display data according to the 4 display modules with which it has a direct connection, obtains the driving display data required by the corresponding 4 display modules, and then sends the parsed driving display data to the corresponding display module. That is, based on Figure 1 In the topology shown, the display module and the receiving card need to be directly connected. Therefore, multiple transceiver ports need to be set on a receiving card for direct connection with the display module. At the same time, when the number of display modules is large, the number of receiving cards needs to be increased accordingly so that each display module can be connected to the corresponding receiving card. It can be seen that the conventional display data transmission topology has the problem of high topology cost.

[0050] Based on the problems existing in the conventional display data transmission topology as mentioned above, a method is proposed as follows Figure 2 The novel display data transmission structure shown is specifically: the novel display data transmission structure is composed of several display data transmission units, each of which includes a receiving card and multiple display modules. The connection structure between the receiving card and the multiple display modules is that each display module is sequentially connected in series to the same transceiver port of the receiving card. The receiving card is used to directly transmit the received total display data to a display module directly connected to it. After the display data is extracted from the received total display data, the required target display data is obtained, and the display is driven based on the target display data. At the same time, according to the series relationship, the received total display data is transparently transmitted to the next display module in the series. That is, according to the series relationship between the display modules and the connection relationship between a display module and the receiving card, cascade transmission of the total display data is achieved.

[0051] According to Figure 2 As can be seen from the topological structure shown, this embodiment avoids the high system processing cost caused by establishing a connection relationship between a receiving card and the corresponding display module and the situation where the number of receiving cards increases proportionally with the number of display modules, that is, it can effectively reduce the cost of the display data transmission topology.

[0052] It should be noted that Figure 2 It shows that the display modules included in a display data transmission unit are divided into two groups, which are respectively connected in series to two transceiver ports of a receiving card. In another embodiment, the display modules included in a display data transmission unit can also be directly connected in series to a group and connected to a transceiver port of a receiving card, thereby further reducing the port resources of the receiving card.

[0053] Furthermore, a first data transceiver port and a second data transceiver port are provided on the display module, and the multiple display modules connected in series include a first display module and several second display modules. The display module arranged on the transceiver port side of the receiving card is the first display module, and the display module arranged in series on the second data transceiver port side of the first display module is the second display module.

[0054] To facilitate the explanation of the following embodiments, the display modules on a single display data transmission unit are distinguished herein, wherein the display module arranged on the transceiver port side of the receiving card and directly connected to the receiving card is determined to be the first display module, and the display module arranged in series on the second data transceiver port side of the first display module and indirectly connected to the receiving card is determined to be the second display module.

[0055] Furthermore, the display data transmission structure also includes a sending card, and several display data transmission units are connected in series; the sending card establishes a connection relationship with a receiving card set in a display data transmission unit set on the transceiver port side of the sending card. Figure 2 It can be seen that the total display data received by the receiving card is output by the sending card. The sending card is connected to the program that generates the display data. After receiving the total display data output by the program that generates the display data, the sending card directly transmits the total display data to a receiving card that has a direct connection with it. The total display data is cascaded and transmitted through the series connection between the receiving card and other receiving cards.

[0056] Furthermore, each display data transmission unit further includes a transfer board Hub, the receiving card is arranged on the transfer board Hub, and other related components or devices can also be arranged on the transfer board Hub.

[0057] It should be noted that according to Figure 2 It can be seen that the sending card and the receiving card, the receiving card and the first display module, the first display module and the second display module, and the second display module and the next second display module are connected in a bidirectional manner. In addition to cascading the total display data received by the receiving card from the sending card based on the series connection between the display modules, the display module can also transmit the relevant display information obtained in the process of driving the display through the receiving card to the sending card through the series connection, and then transmit the relevant display information to the module that processes the display information through the sending card.

[0058] In one possible implementation, see Figure 3 When the display data transmission structure is a wired connection, the transceiver port is the first data transceiver interface In1, the first data transceiver port is the second data transceiver interface In2, and the second data transceiver port is the third data transceiver interface In3, wherein the first data transceiver interface In1, the second data transceiver interface In2, and the third data transceiver interface In3 can be an LVDS (Low Voltage Differential Signaling) interface, a SerDes (Serializer / Deserializer) interface, or other interface forms.

[0059] The first data transceiver interface In1 of the receiving card establishes a wired connection with the second data transceiver interface In2 of the first display module via a connecting cable. The second data transceiver interface In2 of the second display module establishes a wired connection with the third data transceiver interface In3 of the first display module or the third data transceiver interface In3 of any other second display module via a connecting cable.

[0060] like Figure 3As shown, when the receiving card and the display module are wiredly connected, the transceiver port on the receiving card is in the form of a first data transceiver interface In1, the first data transceiver port on the display module is in the form of a second data transceiver interface In2, and the second data transceiver port on the display module is in the form of a third data transceiver interface In3.

[0061] Specifically, the second data transceiver interface In2 on the first display module is connected to the first data transceiver interface In1 of the receiving card via a connecting cable, so that the total display data received by the receiving card can be transmitted to the first display module via the second data transceiver interface In2 based on the connecting cable. The second data transceiver interface In2 on the second display module is connected to the second data transceiver port of the first display module via a connecting cable, so that the total display data received by the first display module can be transmitted to the second display module that has a direct connection with the first display module based on the connecting cable.

[0062] Similarly, the third data transceiver interface In3 on the second display module that has a direct connection with the first display module can be connected to the second data transceiver interface In2 on the next second display module through a connecting cable, ensuring the effective transmission of the total display data when the setting distance between the receiving card and the display module, and between the display modules, is far.

[0063] For details, see Figure 4 As shown, the display module is equipped with a data extraction and transmission chip and multiple display light panels LEDs;

[0064] The first data transmission pin of the data extraction and transparent transmission chip is connected to the second data transceiver interface In2 of the display module, and the second data transmission pin of the data extraction and transparent transmission chip is connected to the third data transceiver interface In3 of the display module. The data output pins of the data extraction and transparent transmission chip are respectively connected to the LEDs of each display light board.

[0065] based on Figure 4 As can be seen, when the connection is wired, both the first and second display modules are equipped with a data extraction and transmission chip and multiple display light panels. The data extraction and transmission chip is used to parse and process the total display data received, obtain the target display data required by each display light panel LED in the corresponding display module, and then transmit each target display data to the corresponding display light panel LED. Simultaneously, the total display data is transmitted to the second display module with which it has a direct connection. The display light panel LED is used to drive the display according to the received target display data.

[0066] In another possible embodiment, see Figure 5, in the case where the display data transmission structure is a wireless connection, the transceiver port is the first wireless data transceiver chip IC1, the first data transceiver port is the second wireless data transceiver chip IC2, and the second data transceiver port is the third wireless data transceiver chip IC3;

[0067] The first wireless data transceiver chip IC1 of the receiving card establishes a wireless connection with the second wireless data transceiver chip IC2 of the first display module. The second wireless data transceiver chip IC2 of the second display module establishes a wireless connection with the third wireless data transceiver chip IC3 of the first display module or the third wireless data transceiver chip IC3 of any other second display module.

[0068] like Figure 5 As shown, when the receiving card and the display module are wirelessly connected, the transceiver port on the receiving card is in the form of a first wireless data transceiver chip IC1, the first data transceiver port on the display module is in the form of a second wireless data transceiver chip IC2, and the second data transceiver port on the display module is in the form of a third wireless data transceiver chip IC3.

[0069] Specifically, the second wireless data transceiver chip IC2 on the first display module directly establishes a wireless connection with the first wireless data transceiver chip IC1 on the receiving card. After the receiving card converts the received total display data into the total display data in the form of a bit stream, it sends it to the second wireless data transceiver chip IC2 of the first display module through the first wireless data transceiver chip IC1 on the receiving card; at the same time, the first display module forwards the received total display data in the form of a bit stream to the second display module with which it has established a direct wireless connection through its third wireless data transceiver chip IC3.

[0070] By analogy, the third wireless data transceiver chip IC3 on the second display module that has a direct connection relationship with the first display module sends the total display data in the form of the received bit stream to the first wireless data receiving chip of the next second display module that has a direct wireless connection relationship with it. When the distance between the receiving card and the display module, and between the display modules, is close, in order to avoid the high laying cost and subsequent maintenance cost of the connecting cables, the transmission of the total display data is completed by setting the port to the form of the first wireless data transceiver chip IC1, thereby avoiding the defects of the connecting cables.

[0071] For details, see Figure 6 As shown, the display module is provided with a data extraction and transparent transmission chip, a first internal transmission interface In4 and a plurality of display light panels LED;

[0072] The first data transmission pin of the data extraction and transparent transmission chip establishes a wired connection with the second wireless data transceiver chip IC2, and the second data transmission pin of the data extraction and transparent transmission chip establishes a wired connection with the first internal transmission interface In4. The data output pins of the data extraction and transparent transmission chip are respectively connected to each display light board LED.

[0073] Furthermore, the display module is also provided with a second internal transmission interface In5 and a data transparent transmission chip;

[0074] The second internal transmission interface In5 establishes a connection relationship with the first internal transmission interface In4, and the second internal transmission interface In5 also establishes a wired connection with the first data transmission pin of the data transparent transmission chip, and the second data transmission pin of the data transparent transmission chip establishes a wired connection with the third wireless data transceiver chip IC3.

[0075] based on Figure 6 It can be seen that when the connection method is wireless, the first display module and the second display module are both equipped with a data extraction and transmission chip, a first internal transmission interface In4, multiple display light board LEDs, a second internal transmission interface In5, and a data transmission chip. Among them, the data extraction and transmission chip extracts the target display data required by the multiple display light board LEDs set in the display module from the total display data received from the second wireless data transceiver chip IC2, and simultaneously transmits the total display data to the first internal transmission interface In4. The parallel total display data is transmitted to the data transmission chip via the first internal transmission interface In4 and the second internal transmission interface In5. The data transmission chip then transmits the total display data to the next display module.

[0076] In the case of a wired connection, both the first and second display modules are equipped with a data extraction and transmission chip and multiple display light panels. The data extraction and transmission chip parses the incoming total display data, obtains the target display data required by each display light panel LED in the corresponding display module, and then transmits each target display data to the corresponding display light panel LED. Simultaneously, the total display data is transmitted to the second display module, which is directly connected to it. The display light panel LEDs are used to drive the display according to the incoming target display data.

[0077] The present application further provides a display device, which includes the display data transmission structure described above. The display data transmission structure includes a plurality of display data transmission units. The connection structure between the same component and other components in each display data transmission unit is the same. The components include:

[0078] The receiving card is used to transmit the total display data received through the transceiver port;

[0079] Multiple display modules connected in series on the same transceiver port of the receiving card are used to extract target display data from the total display data transmitted by the previous component and then transparently transmit the total display data to the next display module in the series.
