It should be noted that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present disclosure, belong to the scope of protection of the present disclosure.

In related art, an existing conference machine on the market cannot be used for implementing other operations during a screen projection conference due to structural limitation, so that participants still need to carry notebooks to record key points. Further, during summarizing discussion after ending of the screen projection, the key points cannot be extracted for discussion in the first time, and need to be written on a blackboard one by one, the process is troublesome, and the efficiency is affected.

That is, the conference device in the related art cannot perform other operations such as writing and recording while performing a video conference, and the effective utilization rate is low.

An embodiment of the present disclosure provides a display device, referring to FIG. 1 and FIG. 2. FIG. 1 is a schematic cross-sectional view of FIG. 2, and the display device includes:

• • a transparent cover plate 1;
  • a display module; the display module is positioned on a side of the transparent cover plate 1, and includes a first display module 21 and a second display module 22; the first display module 21 and the second display module 22 specifically may be independently controlled for displaying; for example, the first display module 21 may be enabled to display only, the second display module 22 may be enabled to display only, and the first display module 21 and the second display module 22 may also be enabled to display simultaneously;
  • a first display control circuit 31; the first display control circuit 31 is positioned on a side, facing away from the transparent cover plate 1, of the display module, and is configured to independently control the first display module 21; and for example, the first display control circuit 31 independently controls the first display module 21 to display conference frames; and
  • a second display control circuit 32; the second display control circuit 32 is positioned on the side, facing away from the transparent cover plate 1, of the display module, and is configured to independently control the second display module 22; and for example, the second display control circuit 32 independently controls the second display module 22 to display recorded information of the conference input by a user.

Optionally, in the display device provided by an embodiment of the present disclosure, the first display control circuit 31 may be electrically connected with the second display control circuit 32.

The first display control circuit 31 is further configured to transmit a control signal to the second display control circuit 32.

The second display control circuit 32 is further configured to control the second display module 22 to cooperate with the first display module 21 for corresponding displaying in response to the control signal.

For example, during conference display, the first display module 21 and the second display module 22 are required to cooperate with each other to form an integrated display area so as to display a video or picture in a conference process. At the moment, the first display control circuit 31 may transmit a corresponding control signal to the second display control circuit 32 so that the second display control circuit 32 controls the second display module 22 to cooperate with the first display module 21 for synchronous displaying, namely. That is, the first display module 21 displays part of the picture or displays part of a picture in the video, the second display module 22 displays the other part of the picture or displays the other part of a picture in the video, and a complete picture or video is formed.

Specifically, in the display device provided by some embodiments of the present disclosure, the first display control circuit 31 may independently control the first display module 21, the second display control circuit 32 may independently control the second display module 22, displaying may be implemented through the first display module, recording may be implemented on the second display module, double screens may display contents synchronously, and may also display contents independently, and thus, the display device has high utilization efficiency when used as a conference device.

During specific implementation, in the display device provided by some embodiments of the present disclosure, referring to FIG. 3, the first display control circuit 31 may include a first display mainboard 311 and a master component 312. An Android system may be installed in the first display mainboard 311. A Windows system may be installed in the master component 312. The master component 312 includes a signal output interface A. The master component 312 may be an open pluggable specification (OPS) component. The signal output interface A may be a high definition multimedia interface (HDMI).

The second display control circuit 32 may include a second display mainboard 321. An Android system may be installed in the second display mainboard 321 which includes a signal input interface B. the signal input interface B of the second display mainboard 321 is electrically connected with the signal output interface A of the master component 312. The signal input interface B may be an HDMI input interface B.

The second display mainboard 321 is configured to control the second display module 22 to cooperate with the first display module 21 for corresponding displaying in response to the control signal transmitted by the master component 312.

Specifically, after the first display control circuit 31 receives a synchronous display command indicated by the user, a mode of driving the first display module 21 by the first display mainboard 311 is switched into a mode of driving the first display module 21 by the master component 312, and the master component 312 is controlled to transmit the control signal to the second display mainboard 321; and after the second display mainboard 321 receives the control signal of the master component 312, the displayed contents of the second display module 22 are controlled according to the control signal. For example, the contents of the first display module 21 may be extended to the second display module 22, namely, the first display module 21 and the second display module 22 serve as an integrated display screen for displaying, or the second display module 22 may be controlled to display the displayed contents which are the same as the displayed contents of the first display module 21, namely, the second display module 22 copies the displayed contents of the first display module 21.

It needs to be explained that the full name of OPS is Open Pluggable Specification, and the OPS is a standardized digital signage interface specification made by Intel and display manufacturers together. An X86 architecture mini PC is formed in the OPS, and an Intel Core processor is adopted, and cooperates with a memory, a hard disk, various input and output interfaces and a Windows operation interface. In some embodiments of the present disclosure, implementation of function expansion is the main purpose. On the one hand, although some embodiments of the present disclosure can meet a daily conference display requirement under the condition of no OPS, bottlenecks may be encountered during manuscript writing and large software running (such as CAD and 3D modeling), and under the condition, an OPS computer needs to be used to enrich and expand the functions of the display device. On the other hand, according to some embodiments of the present disclosure, an interactive display function of a main screen and an auxiliary screen may also be realized through the OPS, and the HDMI output of an OPS module is connected with the HDMI input of an auxiliary screen mainboard (the second display control circuit 32) through an HDMI wire. OPS contents may be transmitted to the auxiliary screen (the second display module 22); when the main screen (the first display module 21) is switched to the OPS mode (Windows system), and the auxiliary screen is switched to the HDMI channel, the main screen and the auxiliary screen may be simultaneously used for displaying, the contents displayed by the main screen may be extended to the auxiliary screen, and the contents of the main screen may also be copied to the auxiliary screen to realize double-screen interaction. In addition, during specific implementation, due to the fact that the main operation system implemented by some embodiments of the present disclosure is the Android system, the first display mainboard 311 and the second display mainboard 321 adopt the Android system, and the cost can be saved. However, lots of application software in the market, especially some large software, cannot well run on the Android system, so that the Windows system of an OPS component is needed to supplement and enhance the functions of the device.

Specifically, in the display device provided by some embodiments of the present disclosure, a main control component 312 provided with the Windows system is adopted to control both display of the first display module 21 and display of the second display module 22, so that the problems that when the first display mainboard 311 is adopted to directly control the second display mainboard 321, the second display module 22 cannot distinguish difference of signals transmitted by the two mainboards due to the fact that the first display mainboard 311 and the second display mainboard 321 are both provided with the same operation system, and the second display module 22 is out of control and cannot work are avoided. The second display mainboard 321 is controlled through the OPS, when the first display module 21 is switched to OPS driving, the second display module 22 only needs to be switched to the HDMI channel, and then the second display module 22 and the first display module 21 may display contents synchronously. If the second display module 22 does not switch the channel, the second display module 22 may also display the contents independently due to the fact that the second display mainboard 321 is provided with the Android system. In addition, an implementing mode of controlling the second display mainboard 321 through the OPS is convenient, the OPS may be connected with the second display mainboard 321 through one HDMI channel only, and the software of the first display mainboard 311 and the software of the second display mainboard 321 do not need to be modified complicatedly.

During specific implementation, in the display device provided by some embodiments of the present disclosure, the second display mainboard 321 is configured to, in response to the switching command of the user, when it is switched that the second display mainboard 321 drives the second display module 22, disconnect a communication with the master component 312, and independently control the second display module 22, and thus, the first display control circuit 31 and the second display control circuit 32 work independently.

In some embodiments of the present disclosure, when the second display control circuit 32 is switched to the Android system driven by the second display mainboard 321, the first display control circuit 31 may be disconnected from the second display control circuit 32, specifically, disconnection may be implemented through software, switching of corresponding functions is realized through the software by switching different signal channels, and if an Android channel is used by switching, the auxiliary screen works independently; and if the HDMI channel is used by switching, the auxiliary screen and the main screen may be used simultaneously, and then the first display module 21 and the second display module 22 may work independently.
