At present, with the increasing popularity of electronic products, the number of electronic devices owned by users, such as notebook computers, desktop computers, etc., is also increasing. In some cases, a user may need to transfer data from one electronic device to another electronic device, for example, the user uses a notebook computer in a company, and also needs to use data in the notebook computer after returning home, and then needs to transfer the data in the notebook computer to a desktop computer at home. Generally, data interaction between two devices can be realized by connecting the two devices through a special data transmission line. However, in practical applications, the current conventional transmission process needs a dedicated data transmission line, which results in that the data interaction function between devices cannot be realized when the user does not carry the data transmission line.
In view of this, embodiments of the present invention provide a display, which is respectively connected to an external first device and an external second device, and can implement a data interaction function between the devices. Specifically, the display according to the embodiment of the present invention may be as shown in fig. 1, where the display includes:
a first device interface 11, a second device interface 12, a display control module 13 and a data transmission module 14;
wherein, the display control module 13 is connected to the first device through the first device interface 11 so as to receive the display information of the first device;
the display control module 13 is further connected to the second device through the second device interface 12 so as to receive display information of the second device;
the first device interface 11 is further connected to the second device interface 12 through the data transmission module 14, so as to enable the interaction of the control signal and the interaction of the file data between the first device and the second device.
In this embodiment, the first device may be connected to the display control module through the first device interface, so as to transmit the display information of the first device, and the second device may be connected to the display control module through the second device interface, so as to transmit the display information of the second device, so that the display control module can perform a synchronous output effect of the picture contents of the two devices based on the display information of the two devices. Moreover, the first device and the second device can realize the interaction of the control signal and the interaction of the file data through the first device interface, the second device interface and the data transmission module, so that the data transmission and the transmission of the control signal can be realized between the two devices, that is, the two devices can be controlled according to the requirements no matter whether the control signal comes from the first device or the second device, and then the picture contents of the two devices can be synchronously displayed and simultaneously the control function and the data transmission function of the two devices can be realized based on the control signal.
It should be noted that, in this embodiment, the first device interface and the second device interface may be a composite multi-purpose interface having functions of display information transmission, control signal transmission, and file data transmission, or may be formed by interfaces with several different functions, which are not limited herein, as long as the functions of display information transmission, control signal transmission, and file data transmission are ensured. For example, in practical applications, the first device interface may be a USB Type-C interface, and since the protocol of the interface adapts to a bi-pass channel function, that is, one of the two channels may perform transmission of display information, and the other channel may perform transmission of a control signal and transmission of file data, the USB Type-C interface may be used to replace two different interfaces, thereby saving interface locations of the display and simplifying design layout.

In this embodiment, the first device simultaneously implements transmission of display information, interaction of file data, and interaction of control instructions through one interface (i.e., the first interface), which ensures that the above functions are implemented, and at the same time, reduces the number of additional interfaces, and saves the interface layout of the display. In addition, since the second device performs the interaction of the file data and the interaction of the control command through the second interface, and performs the transmission of the display information of the second device through the third interface, it is ensured that different transmission functions are respectively performed through different interfaces, for example, the second interface may be a USB Type-B interface, and the third interface may be an HDMI interface. Since different picture transmission interfaces (such as HDMI interface) and USB interface (USB Type-B interface) are provided in a general display, it is ensured that when the second device is transmitted in the above manner, the existing interface can be used for directly transmitting, and there is no need to provide an additional dedicated interface for transmitting control signals, file data, and display information, so that the effect of implementing the above transmission function by using a conventional interface is achieved, and the design cost of the display in this embodiment is saved.

In this embodiment, the transmission control chip is a chip having a data transmission function for control, and the transmission sub-module can be understood as a module having a plurality of transmission channels, so that control based on the transmission control chip can implement interaction of control signals between the first device and the second device, which are respectively connected to the first interface and the second interface, and implement an interaction function of file data.
In an alternative embodiment, as shown in fig. 5, the transmission sub-module 142 includes: a USB selector 1421, a first USB expander 1422, and a second USB expander 1423;

the USB selector 1421 may also be used to connect with the control signal access module 15.
In this embodiment, the USB selector is connected to the control signal access module, and after the control signal access module receives a control signal from an external controller, the control signal access module may select and determine the control signal based on the USB selector, so that the control signal is transmitted to the first device through the first USB expander and then the first interface to control the first device, or the control signal is transmitted to the second device through the second USB expander and then the second interface to control the second device, and after the display receives the control signal based on the control signal access module, the function of the device to be controlled may be selected based on the user's requirement. In addition, the first USB expander and the second USB expander realize the expansion function of the transmission channel, so that the realization of two channels of control signal transmission and file data transmission is ensured.
