Hereinafter, embodiments of the present utility model will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present utility model provides a display system, including:
A processor 1 having at least a first display interface 2;
The first transfer switch 3 is connected with the first display interface 2;
A first transmission line 4 connected to the first transfer switch 3 and the first data interface 6 of the electronic device for transmitting the first data;
A second transmission line 5 connected to the first transfer switch 3 and a second data interface 7 of the electronic device, for transmitting second data, the second data being different from the data protocol corresponding to the first data;
When the first data interface 6 or the second data interface 7 is connected to the external display device, the first transmission line 4 or the second transmission line 5 transmits the target signal to the first switch 3, and the target signal is transmitted to the processor 1 by the first switch 3, and the processor 1 determines the target data interface connected to the external display device based on the target signal, and controls the first switch 3 to conduct the transmission line connected to the target data interface and the data channel between the processor 1.
For example, if the first data interface 6 is connected to the display device, the HDP signal is generated at the interface, but other signals for prompting that the display device is connected to the interface, that is, the target signal, may be generated, which is not unique, and the present embodiment will be described taking the target signal as an HDP signal as an example. The generated HDP signal is transmitted to the first transfer switch 3 through the first transmission line 4, and is transmitted to the processor 1 by the first transfer switch 3, and after the processor 1 receives the HDP signal, the processor 1 can directly determine the source of the HDP signal, that is, determine the HDP signal to be the signal generated by the first data interface 6, which indicates that the first data interface 6 is connected to the display device, at this time, the processor 1 controls the first transfer switch 3 to conduct a channel between the processor 1 and the first transmission line 4, so as to interact with the external display device based on the channel and the first transmission line 4. Similarly, when the second data interface 7 is connected to the display device, the processor 1 controls the first switch 3 to switch on the channel between the processor 1 and the second transmission line 5, so as to interact with the external display device based on the channel and the second transmission line 5. Since the formats of the data transmitted by the two transmission lines, that is, the data protocols are different, the display system according to the present embodiment can enable the processor 1 to realize a matched connection with at least two data interfaces for transmitting the display data with different formats when only one display interface is provided.
In this embodiment, the number of data interfaces and the number of transmission lines are not fixed, and this embodiment only shows that the first display interface 2 can be connected with at least two different data interfaces, and implement interaction of corresponding data, without adding a physical interface related to display, so that, based on the same principle, when one display interface is matched and connected with more data interfaces, such as three, four, etc., the method is still adopted, and only the number of transmission lines is required to be increased, and meanwhile, a change-over switch with a multiple switching function is used. That is, in this embodiment, there is at least one first transmission line 4 and at least one second transmission line 5, and there may be at least one change-over switch, i.e. there may be a plurality of change-over switches, for example, the structures of this embodiment may be duplicated and all connected to the first display interface 2, which is not a limitation on the structure of the display system of this embodiment.
Based on the foregoing embodiment, the beneficial effects of this embodiment include that by setting the first change-over switch 3 and the transmission lines respectively connected with different data interfaces of the electronic device, the processor 1 can control and conduct the data channels between the different data interfaces through the first change-over switch 3, so as to realize the matching connection with multiple interfaces of the electronic device without increasing the physical interfaces of the processor 1, thereby meeting the requirements of the electronic device or the user on different display resources.
With continued reference to fig. 1, the processor 1 in this embodiment further includes a second display interface 12 for connecting to a display. Of course, more display interfaces may be included, as is specific.
Further, the data protocols of the first data and the second data are different, but the first data and the second data may be the same kind of data, or may be different kinds of data, for example, both display type data and display type data, and the other is non-display type data, which is specific and variable. For example, as shown in fig. 2, the data protocol of the first data may be, but is not limited to, a DP protocol, the data protocol of the second data may be, but is not limited to, a HDM I protocol, or both, a DP protocol, a type c data protocol, and the like.
In this embodiment, the interface protocol of the first display interface 2 is different from that of the first data interface 6, that is, the data interfaces are different, for example, the first display interface 2 is a DP interface and the first data interface 6 is an HDM I interface. In order to realize the transmission of the display data, the processor 1 can receive and process the display data or output the display data, and the external display device can display the data output by the processor 1, as shown in fig. 1, the first transmission line 4 is provided with a protocol converter 13 for performing protocol conversion on the data received by the first data interface 6 to match the data transmission requirements of the first display interface 2 and the first data interface 6.
In another embodiment, the display system further comprises:
a second transfer switch 10 provided on the second transmission line 5;
A third transmission line 8 connected to the second transfer switch 10 and the second data interface 7, respectively, for transmitting third data;
A fourth transmission line 9 connected to the second change-over switch 10 and the second data interface 7, respectively, for transmitting fourth data, the third data being different from the fourth data in data type;
When the second data interface 7 is connected to the external display device, the third transmission line 8 or the fourth transmission line 9 transmits the target signal to the second transfer switch 10, and the second transfer switch 10 switches on a data channel between the transmission line for transmitting the target signal and the first transfer switch 3 based on the target signal.
In this embodiment, the third data is display data, and the fourth data is non-display data. As shown in fig. 2, the first data interface 6 in the present embodiment is an HDMI interface, that is, a display data interface, and the second data interface 7 is a typec interface, which is capable of transmitting DP data as well as USB data.
As shown in fig. 1 and 2, the second transfer switch 10 in the present embodiment is connected to the target controller 11 in the electronic device at the same time, and when the second data interface 7 is connected to the non-display device, the second transfer switch 10 turns on the data channel between the third transmission line 8 and the target controller 11. When the second data interface 7 is connected to the display device, the second transfer switch 10 turns on the data channel between the fourth transmission line 9 and the first transfer switch 3.
For example, with the target controller 11 as a PD controller, when the TYPE C interface is plugged into the display device, the second transfer switch 10 will conduct the data channel between the fourth transmission line 9 and the first transfer switch 3 according to the HDP signal transmitted by the fourth transmission line 9. Or the second transfer switch 10 may be controlled by the target controller 11, as shown in fig. 2, when the PD controller determines that the type interface is connected to the display type device through the CC signal generated by the second data interface 7 and transmitted through the third transmission line 8, the typec MUX (second transfer switch 10) is controlled to switch the signal path to the DP path, the HPD signal of the DP path is pulled high, and the control DP SWITCH IC switches the DP signal of the CPU to output to the TYPEC paths DP, so as to provide a display function through the TYPEC interface. If the non-display type device is accessed, the second transfer switch 10 is controlled to conduct the data channel between the target controller 11 and the second data interface 7.
Alternatively, when both the first data interface 6 and the second data interface 7 access the display device, for example, after the HDM I interface and TYPEC interface are simultaneously inserted into the display device, the display may be output only from the HDM I interface by default or based on the input selection information, or only from the TYPEC interface.
Another embodiment of the utility model also provides an electronic device comprising a display system as claimed in any one of the preceding claims. The electronic device in this embodiment may be, but not limited to, a notebook computer.
The above embodiments are only exemplary embodiments of the present utility model and are not intended to limit the present utility model, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this utility model will occur to those skilled in the art, and are intended to be within the spirit and scope of the utility model.
